MACHINE FOR TRAPPING BOXES.

Application filed October 17, 1921.

To all whom it may concern:

Be it known that we, MARTIN FEYBUSOH, a citizen of the United States, and resident of the borough of Manhattan, city, county, and State of New York, and PAUL W. Fnnrsonnn, a citizen of the United States, and resident of \Veehawken, in the county of Hudson and State of New Jersey, have jointly invented certain new and useful Improvements in Machines for WVrapping Boxes, of which the followingis a specification.

In the manufacture of boxes, and particularly of boxes made of pasteboard and similar materials, it is customary, in a certain type of box to wrap a single or a compound strip of paper or like flexible material around the body of the box, or the cover thereof, said strip being provided with a coating of paste or other adhesive substance on the side engaging the box part, and projecting therefrom for the purpose of formin edge portions to be bent or folded against the box part. Our present inven' tion relates to a machine of the general type just set forth, and has for its object to provide an increased certainty of operation, so that the machine will perform its work accurately, and that the loss through breakage of jammed box parts will be reduced or eliminated.

A satisfactory embodiment of our invention, as we prefer to use it in practice, is illustrated by the accompanying drawings, in which Figs. 1 and 2 are side elevations of a part of the machine, with parts in section, said two views showing difierent positions; Fig. 3 is a partial end elevation, showing principally the bottom folders and a box retainer; Fig. 4 is an end view of the box and its carrier or holder; Fig. 5 is a detail elevation, with parts in section, of the cam mechanism for operating the box retainer; Fig. 6 is an elevation, with parts in section, showing chiefly the top folders, the paper pressers, and the box-receiving die: Fig. 7 is a top view showing the parts of Fig. 6 in a diiferent position, partly in secion on the line 77 of Fig. 6; Fig. 8 is a horizontal section substantially on line SS of Fig. 6, but showing the parts in the same position as in Fig. 7 Fig. 9 is a de Serial No. 508,356.

tail horizontal section of the box, die, and two of the top folders, in a position intermediate between Figs. 6 and 7; Fi 10 is a section on line 10-10 of Fig. 4; Fig. 11 shows the box in the wrapping position; Fig. 12 is a partial section similar to Figs. 8 and 9, but showing the parts in the same position as Fig. 6; Figs. 18 and 14: are sections on lines 1313 of Fig. 2 and 14. 14: of Fig. 13 respectively; Figs. 15 and 16 are elevations of two strips forming part of the machine; Fig. 17 is a detail elevation of one of the top folders and its carrier; Fig. 18 is a section on a line 1S-18 of Fig. 17 and Fig. 19 is a diagrammatic elevation.

For the sake of simplicity, we shall use the term box in this description to designate either the body of a box or the cover thereof, since both of these parts are similar and are wrapped with a strip of paper or the like, in the same manner. A brief explanation of the sequence of operations performed by the particular machine illustrated herein is as follows: The box is first contained in a carrier or holder, from which it is expelled by the action of a plunger or core entering the box; while the box is on the plunger, the latter is rotated to apply to the box, the end of which is held between said plunger and a yielding box-retainer, a strip of paper or other flexible material the edges of which project beyond the side walls of the box both at the closed end or so-called bottom, and at the open end or socalled top. The strip having thus been wrapped around the box, the plunger, with the box thereon, is brought from the position in which it registers with the wrapping device, to another position in which it brings the box into operative relation to folders which bring one projecting edge of the wrapped strip against the bottom of the box. The retainer, which until that time has remained in engagement with the box bottom, is then moved out of the way, clearing the path of the box which is brought forward by a further advance of the plunger, against and into a die which at that time is in line with the path of the plunger. The latter is then retracted from the box, which remains held by the die, and this die, with the box, is then moved transversely, to a different position, and during this transverse motion the projecting edge of the strip at the open end of the box is folded ii wardly into a plane perpendicular to the sides of the box. Thereupon another plunger, operating in line with the second posi tion of the die, advances into the box to fold the top edges of the paper strip against the inner surfaces of the box sides, that is to say, into the box. After this operation, outside pressers press the paper strip firmly against the outside of the box, and also cause the inwardly-folded top edges of such strip to be pressed tightly between the second plunger (the pressure-plunger) and the side walls of the box. Then ejector engaging the box bottom on the outside, moves the box out of the die which has been holding it, and the pressure-plunger is retracted, the box coming into engagement with stationary stops which cause it to be stripped off the pressure-plunger as the latter is retracted.

The particular container or holder shown in Figs. 1, 2, 41-, and 10 comprises two spaced members or carriers 20 located at the same level an d carrying the box-guiding and boxholding parts. The box (which may be either a box body or a cover), when received within said container or holder, has one of its four side walls 21, which at that time is lowermost, resting on two projections 22 extending toward each other from the lower ends of two vertical bars 23, secured to a pair of substantially vertical side walls 2% adapted to act as guides for the two side walls 21 which at that time are vertical. The bars 23 are secured to the guides 2a in any suitable manner, as by screws 25, preferably in such a way as to allow the bars 23 with their box-supporting projections 22 to be adjusted up and down, for which pun pose said bars may be slotted vertically, as indicated at 26, for the passage of said screws, the latter being drawn up tight after the desired adjustment has been made. The guides 2-1, which preferably diverge at their upper ends as shown, to facilitate the entrance of the box, are secured rigidly to rackets 27, which are fastened to the carriers 20, preferably in such manner as to allow these brackets to be adjusted horizontally toward and from each other, for which purpose these brackets may be slotted horizontally in a manner corresponding to that explained with reference to the bars 23. To the guides 24; are secured bearings 28 for vertical shafts 29. and on these shafts are mounted horizontally-rocking arms 30, 31, the portions 30 being formed, with eyes as shown best in Fig. 10, and the portions 31 being connected at their free ends by vertical abutment bars To the guides 24: are also secured rigidly horizontal pins extending loosely through c; ings of the arm porand "irryic collars or washers 3i 85, the inner ends of which press the arms 30, 31 toward each other and. into engagement with the guides 24, the bars 32 having seats or engaging surfaces 32 normally in the path of the closed end or bottom 36 of the box A.

We have also indicated the following mechanism for delivering to the container or holder, partly-finished boxes, that is to say, boxes each comprising a flat end wall or bottom and four side walls perpendicular to said bottom, said side walls preferably having overlapping ends pasted together: A chute 37 of open-work character, and preferably adjustable to different sizes of boxes, is arranged to feed or guide the said boxes from a magazine (not shown) or otherwise to the box-holder when the latter is in registry with the lower or delivery end of said chute, as in Fig. 1; the open side or end of each box will face toward the left in Fig. 1, and the closed end or bottom toward the right. The guides 24: are adjusted to such a distance from each other that at the time a box is allowed to slide down from the chute 37 to the holder, such lowermost boX will by its own weight drop into contact with the supporting projections 22, as in Figs. 1 and 4;, the weight of the other boxes assisting in pressing su'ch box down. The holder is open not only at the top, for the introduction of a box from the chute 37, but also on the two ends which correspond to the open end and to the closed end of the box respectively; that is to say, the holder is also open at the left and at the right in Figs. 1 and 2.

While we have shown a wrapping machine having a holder to which partly-finished boxes (produced elsewhere) are supplied from a chute, we desire it to be understood that this is immaterial so far as certain broad features of our present invention are concerned, and instead of being fed through a chute as set forth, in a partly-finished condition, the boxes might be produced on the wrapping machine itself, for instance in the manner disclosed in the pending application for Letters Patent of the United States, Serial Number 417,014 filed on October 14. 1920 by one of 115 (Martin Feybusch) and Sigurd Severson, in which case the former 42 of said co-pending application would take the place of the box-holder or containelr of the present application (indeed, said former might be termed a box-holder or container), while the core ll of said earlier application would correspond to the.

core or plunger 88 of the present case.

This core or plunger 38 is of proper rectangular shape to enter the box A fitted within the holder or container, and. prefer ably the front edges of the core are rounded as shown so that it may enter the box readily and cause such box. to become properly centend the core In order to fit boxes of:

this longitudinal movement taking place in stage as exp mined below. We have not illustrated herein any particular mechanism for effecting th s longitudinal motion and the rotation of the core 88, since thismechanism may be of the same character as shown in the earlier application mentioned above, or any other mechai. sm that will accomplish the desired result may be employed.

At the time the holder is in position to re ceive a box, as in 1, the L'OlQ 88 is retracted fully, being in the extreme position to the left, as shown in F 1, and also helps to guide the open end of the descending box. The box-holder, while. non-rotary, is movable lengthwise of the axis of the shaft 39; for this purpose, the carriers 20 are secured to two horizontal rods 410 parallel to the shaft 39 and arranged on opposite sides thereof. Alongitudinal sliding movement may be imparted to the said rods and to the box-holder in the proper direction and at the proper time in anv suitable manner, for instance by means of the character set forth in our aforesaid earlier application with reference to the movement of the formei 4:2. The shaft 89 and the rods a0 are shown supported in a stationary member il forming part of the frame of the machine.

While the parts are in the position inclicated in Fig. 1, the box A immediately above the one in the holder is lifted out of contact with said lowermost box. in any suit able manner. is an instance of mechanism for retaining temporarily in the chute 37, the boxes contained therein. and for, effecting the release of the box in the holder, from the weight of the other boxes. we have shown a rocking arm or finger 4L2, fulcrumed onastationarypart at -l3nvhich finger in one position, Fig. 1, clears the 'iath of the boxes A so that they may slide down freely in the chute 37. At the proper moment through suitable mechanism (not shown) controlled automatically from the main shaft or some other moving part of the machine. this (in ger is rocked to the position shown in Fig. 2, in which it enters the open end of the lowermost box A contained in said chute, through a suitable opening in the left-hand wall of the chute, and by hearing against that sidewall 21 of the said box which is at the top of the box. lifts said box as shown. thereby supporting this box and all those above it, and freeing the lowermost box A, which is in the holder. We may add that the finger 42 is, for the greater part of the time, in the position shown in Fig. 2, the position F ig. 1 being taken only at the time a. box is to be fed from the chute 37 to the holder.

The core 38, which at the time stands in a position corresponding to that of the holder and of the box therein, that is, with the side edges vertical and horizontal respectively, is then moved from the extreme position indicated in Fig. 1, toward the right, to an intermediate position such as indicated by dotted lines in Figs. 1 and 2, this movement of the core being purely longitudinal, without rotation. At the same time, the holder is retracted from the position shown in Fig. 1, to that shown in Fig. 2, so that the holder. which originally was in advance (to the right) of the core 88, will now be at the rear (to the left) thereof. This movement of the holder and of the core past each other in opposite directions, causes the core to enter the box carried by the holder, and said box to be stripped oil the holder and transferred to the core. In order to insure the cores entering the box fully, so as to come in contact with the closed end or bottom 36 of the box, we have provided on the holder, yielding stops, such as the bars 32, adapted'to engage the box bottom 36 on the outside (on the right in Figs. 1 and 10). These will oppose a sufficient resistance to a movement of the box relatively to the holder, to the right, to compel the box and holder to move in unison toward the left, notwithstandingany frictional engagement of the core 38 with the inner surfaces of the side walls 21, until the end of the core comes in contact with the inner surface of the closed end or bottom 36; from that moment on, the box will move in unison with the core, and not with the holder. the stops or bars 32 yielding to let the box pass between them.

While the core 38 is in the intermediate position referred to above, i is in operative relation to i'uechanism for wrapping a strip a l of paper or other flexible material around the box, the core being rotated for this purpose in any approved manner. the principle of this ope ation being well-known in the art; a suitable wrapping mechanism is set forth in our earlier application herein referred to, and in the present case we have deemed it sufficient to indicate the wrapping strip 14 and a roller 45 which forms part of the wrapping mechanism, said. roller press ing the gummed strip against the outside of the box walls 21 as the corerotates. (l' igs. 1, and 11.)

novel feature of our present invention 13' is of: importance in conjunction with th oping step and subsequent stages of t e operation. conmsts in a box-retainer 4-6 adapted to engzjage the box bottom 36 on the outside, both during the wrapping and during certain steps subsequent thereto, as will be set forth below. T his retainer preferably is made as a roller mounted to turn about an upright axis at the lower end of arm a? which at its upper end has a pivotal connection #18 about a horizontal 's transverse to the direction in which the box-holder and the core 38 move; by this connection 48 the arm a7 is hung from a lever fulcrumed on the frame of the machine 50, about. a horizontal axis parallel to the pivot 18. The opposite, left-hand end of the lever 19 is connected with mechanism for rocli'ing' said lever and operating the r tainer 46 at the proper times; we have shown an upright rod 51 the upper end of which is pivoted to the lever 19 at 52 about an axis parallel to 18 and 50, while the lower end of the rod 51 is secured to a guide member having a portion 5a straddling a shaft (which may be the main shaft of the machine), and provided with a roller 56 we "King in a cam. groove 57 on a disk 58 carried by said shaft to rotate therewith. A spring 59 tends to pull the arm t? toward the lever 49, and to keep said arm, in its initial position illustrated by Fig. 1, in contact with a guide (preferably a roller) 60 mounted on a stationary portion of the machine. As the box and core approach the wrapping position indicated by dotted lines in 1 and 2, and slightly before this position is reached, the retainer 46 will come into engagement with the box bottom 36 on the outside thereof, and the pressure of the spring 59 will thus be exerted through the said retainer 4:6 to keep the box A in proper position against the core 38. If no retainer is employed, there is danger that the box, owing to the rapid motion of the parts and the momentum acquired by the box, or owing to other causes, will become loose on the core; or fly ahead of its proper position, as it were. lVith the use of our retainer. the box is held with certainty in proper position for wrapping and for certain subsequent operations.

In the wrapping position; therefore, the arm 47 is out of contact with the roller (3U, although not quite so far away tl'ierefroin as indicated in Fig. 2 (full lines) which illus- The strip l-l,

trates a subsequentposition. in the machine shown, is wrapped around the box A in. such a manner that the edges of the strip will project from the both at the closed end or bottom 31}, and at tile open end, see Figs. 2 and ill, which show the strip 44 as of greater width than the sides 21 of the box, and as projecting therefrom both at left and right.

The strip 44 having been wrapped around the box, its projecting edges are to be folded against the box. First the edges project inn: adjacent to the clos end or bottom 86 folded. that i".- the s .i-e: ed hottom edges. For this purpose, the core 38 with the box thereon, is advanced from the wrapping position (dotted lines in l and 2), to the bottom-edge folding position, indicated by full lines in Fig. 2. The spring 59 will yield to allow the arm 4:? to room slightly more to the right, and the retainer will therefore press with slightly in creased force against the box bottom 36,

holding the latter quite firmly against the core 38 in this position. This movement of the core brings the outer (righthand) sur face of the bottom 36 close to the path of bottomedge folders 62, mounted to slide horizontally and vertically respectively in a suitable stationary support having an opening wide enough to allow the box ll. and the core 88 to pass therethrough. It will be understood, particularly with reference to Fig. 3, that at the end of the wrapping operation the core and the box thereon are in a position with the. sides 21 vertical and horizontal respectively, so as to co-operate properly with the inner edges of the bottom- edge folders 62 and 63 respectively. The arrangement and the operation of these folders may be varied; a suitable mechanism for operating such folders is disclosed in the earlier application mentioned above, but we do not desire to restrict ourselves to sliding folders, or to any specific mechanism for operating the bottomedge folders. It will be understood that the function of these folders is to bend or fold the bottom edges of the strip 14 until they all lie in the same plane, flat against the outer surface of the closed end or bottom 86.

When this operation has been performed, the box-retainer a6 is moved out of contact with the bottom 36, and out of the path of the box A, to the, inactive position indicated by dotted lines in Fig. 2; this movement of the retainer 46 and of the arm 4:7 is effected by the action of the cam groove 57 on the roller 56, said arm coming in contact with the roller 60, and sliding over it.

The box-retainer having thus been swung out of the way, the core 38 with the box A thereon, and with the wrapped. strip let folded against the outside of the bottom 36, at the right-hand edge of said strip, is moved still further toward the right, to the end of its right-hand throw or stroke, thereby carrying the box it. into a die which at that time is in position to r ceive the box. The resulting position is substantially as shown in 8, except that the latter illustrates a slightly later stage at which the core 38 is no longer within the box. The core 38 at the end of its stroke to the right (forward stroke) brings the bottom 36. or rather the folded edge of the strip 14 which lies against said bottom, into contact with a back-plate 66 which forms part of the said die. This back pate an op in -67 fer the passage of an ejector described hereinafter, and is preferably removable and ex changeable, dilterent back-plates being used for diii'erent-sized boxes. /Ve have indicated a. back-plate adapted to slide in dovetail fashion, in vertical guideways 68 of two vertical side strips 69 which are secured, as by crews 70, to a slide 71 movable horizontally, in a direction transverse to the shaft 39 and to the rods 10, in guideways 72 of a stationary frame portion 73 (Figs. 8 and Any suitable mechanism is provided for reciprocating this slide 71 along the guideways 72, for instance, as indicated at 7 1 in Fig. 8, said slide may be connected pivotally with a pitman or actuating rod 75 receiving its motion from the main shaft in any suitable manner. The strips 69 carry hubs 76 integral or rigid therewith, and through these hubs extend rods 77, perpendicular to the plane of the slide 71, and parallel to the shaft 30 and rods 40. The rods 77 may be adjusted in the hubs 76 lengthwise, and secured in position after adjustment, by means of set screws 7 S. The rods 77 carry vertical strips 79 (Figs. 8 and let) on which are mounted carriers 80, S1 respectively. The carriers 80, 81 are provided with horizontal slots 82, 83 respectively (Fig. 6), which are parallel to the direction in which the slide 71 moves, and through these slots extend screws 84, 85 respectively, screwing into the said strips 79. Normally, the screws are drawn tight so that the carriers 80, 81 are rigid with the slide 71, but upon loosening said screws, the carriers 80, 81 may be adjusted individually toward or from each other, to adjust relatively to each other, vertical strips 86, 87 respectively which are connected with said carriers and which engage the two vertical side walls 21 of the box A. The strip 86 is secured rigidly to its carrier 80, but the other strip, 87, is movable relatively to its carrier 81, in the same direction in which the carriers 80, 81 are adjustable relatively to the strips 79. For this purpose, the strip 87 is secured to a plate 88, from which extend. horizontal rods 89, parallel to the path of the slide 71, and forming guides for a sliding crosshead 90, the rods 89 being suitably guided for sliding movement in the carrier S1, in a direction parallel to the path of the slide 71. The cross-head 90 is adapted to be pressed against collars 91. secured to the outer ends of the rods 89, by springs 92 coiled around said rods and bearing with one end against the cross-head. and with the other against collars 93 rigid on said rods. The cross-head 90 is further urged outwardly relatively to the carrier 81, by springs 94 the respective ends of which engage the said carrier and said cross-head, see Fig. 6. In the central portion of the cross-head is secured an abutment 95. preferably adjustable lengthwise of the path of the slide 71, for which purpose said abutment may consist of a screw screwing into the cross-head 90, see Figs. 6 and S, and extending loosely through the carrier 81, said screw, after adjustment, being locked against turning, by means of a set screw 95. In a bracket 96. rigid with the rams portion 7 3, is journaled at 97 a rocking elbow lever 96, one arm oi? which is adapted to engage the abutment 95, while the other arm is adapted to be engaged by operating mechanism described below.

The vertical strips 86, 87 have their lower ends close. to av horizontal strip 99 (Figs. 6 and 8) of similar character, adapted to enthe lower horizontal side wall 21 of the box A, and this strip has preferably attached thereto an additional support 100 extending toward the back plate 66. The strip 99, with said support 100, is adjustable up and down along the vertical strips 79. A major vertical adjustment may be ellected by transferring up or down, the screws 101 which normally hold said strip 99 rigidly on the strips 79; for thispurpose, we have shown the strips 79 as having a series of vertically-superposed screw-threaded openings 102 to receive said screws 101 (Figs. 6, 15 and 16). A minor or more accurate up and down adjustment oi the strip 99 may be eflectcd by loosening the screws 101, and then sliding said strip up Or down to the desired extent. the ends of the strip being provided with vertical slots 103 through which said screws extend, the screws being tightened after the adjustment.

Adjacent to the upper ends oi the strips 86, 87, but normally out of contact therewith, as indicated by the space 10st (Fig. 6), is an upper horizontal strip 105, similar in shape and length to the lower strip 99. the latter, however, being in contact with the. lower ends or" the strips 86. 8. and normally rigid with the strips 79; on the other hand. the upper strip 105 is movable vertically toward the upper ends of the strips 86, 87. Fig. 6 showing the raised position of the strip 105. To effect a downward movement of the strip 105, we have shown vertical rods 106 connected with said strip rigidly. said rods being fitted to slide in suitable bosses forming part of a carrier 107 which is normally rigid with the strips 79, but may be adjusted relatively thereto by a construction similar to that set torth in connection with the lower strip 99. Thatis to say, the strips 79 have a second series of vertically superposed threaded openings 102'. adapted to receive the screws 108 extending through vertical slots 109 of said carrier 107. The rods 106 also extend through a cross-head 110 (similar to the cross-hcad 90), and springs 111 interposed between said cross-head and the bosses on till the carrier 107 tend to keep said cross-head in its outer position, against collars 112 at the outer ends of the rods 106, thereby tending to keep the upper strip 105 in the outer or upper position shown in Fig. 6, that is to say, against the carrier 107. The rods 106 extend through the cross-head 11 loosely, so that the latter may have a limited sliding movement on said rods, between the collars 112 and inner. collars 113, cushioning springs 11 1 being coiled around the rods 106 between the said collars 113 and the cross-head 110. Through the central portion of the cross-head extends an abutment, here shown as a screw 115 having threaded engagement with the cross-head, the outer or upper end of said abutment being adapted for engagement with operating mechanism as will be described below, and after being adjusted up or down relatively to the cross-head to the desired position, the abutment 115 may be locked by a set screw 116. It will be noted that the mechanism connected with the upper strip 105 is similar to that described in connection with the movable vertical strip 87. li e may add that the carrier 81 of said movable strip 87 is preferably also adapted for a major adjustment in addition to the minor adjustment set forth above, and for the purpose of this major adjustment the strip 79 on which said carrier is mounted has a plurality of openings 79 (Fig. 16) for each of the screws 85, the openings for the same screw being located at the same level. so that the screws 85 may be shifted to different positions, right or left, thereby providing a greater range of adjustment than is obtained by the slots 83 alone. A. similar arrangement maybe provided for the screws securing the carrier 80.

In a position adjacent to the strip 36 when the latter by the transverse movement of the slide 71, has been carried to the position shown in Fig. 6, is located a vertical shaft 117, mounted to rock in arms 118, 119. The lower arm 119 is carried adjustably by a rod 120 secured to a stationary part of the machine, for instance the support 61 of the bottom-edge folders 62, 63 (see Fig. 2) 5 this stationary rod 120 extends transversely to the path of the slide 71, and after adjustment along said rod, the arm 119 is locked by a set screw 121 or in any other suitable manner. The upper arm 118 is made integral or rigid with a bar 122 parallel to the rod 120 and slotted lengthwise for the passage of an adjusting and locking screw 123 by which said bar is secured adjustably to a bracket 124: secured to the frame portion 73. On the rock shaft 117 is secured rigidly an arm 126 carrying a roller 127 adapted to engage a cam 128 which is secured to the lower ends of the strips 79 (Figs. 6 and 7). A spring 129 tends to rock the shaft 117 in such a manner as to keep the roller 127 in contact with the cam 128. The shaft 117 carries rigidly a yielding folder blade or strip 125, extending vertically not quite to the level of the upper ant the lower ends of the strips 86, 87 (Figs. 6, S and 9).

The arms 118, 119 are connected by a bar 130 fastened thereto by screws 131, and along this vertical bar are adjustable two brackets or carriers 132 (Figs. 6, 17 and 18), locked in position by screws 133 extending through slots 132 of the brackets, this arrangement permitting a minor adjustmentof the brackets up and down. A major adjustment may be obtained by engaging the screws 133 with different openings 130 of the bar 130. To the carriers 132 are pivoted about vertical axes 13 1, folders 135 urged by springs 136 againstpositioning set screws 132 and adapted to engage and fold the horizontal portions of that part of the strip 41 which projects at the open end of the box (the soealled top) the folder blade 125 is adapted to engage one of the vertical portions of the projecting strip 44, at the open end of the box.

For folding the other vertical portion of the strip 4:41, at the open end of the box, we have provided the following mechanism On .he carrier 80 are mounted rigidly two horizontal guides 137, parallel to the path of the slide 71, and along said guides is movable a slide 138 carrying vertieal folder 139 the upper and lower end portions of which project far enough to over lap the folders 135, or at least the lo wer portions of said folders; the upper and lower ends of the folder 139 may, for instance, be at substantially the same levels as the opposing or operative surfaces of the strips 105 and 99 respectively. To operate the folder 139, we have. provided a bell crank lever 1410, fulcrumed on the left-hand strip 79 at 1 11, and; having a pin-and-slot connection 14-2 with the slide 138 (Figs. 6 and 8). The lever 140 carries a roller 1 13 traveling in a suitable groove of a cam 1 14: which extends parallel to the path of the slide 71. The cam 14-1 is normally stationary, lnrt may be adjusted toward or from the frame portion 73. For this purpose, the cam has bosses through which extend parallel rods 14:5 (Figs. 6 and 7 set screws 1416 serving to lock the cam to said rods after adjustment. The rods 145 have their inner ends fitted into bosses formed on a bracket or carrier 14-7 secured to the frame portion 73, and pins 1418 are shown as means for securing the rods 145 to said carrier.

Fig. 6 shows the following mechanism for operating the movable strips 87 and 105: (hi the frame of the machine is j ournalcd a shaft 1419 to which a rocking motion is imparted at the proper times by a cam or other suitable mechanism of any approved character (this mechanism is not shown). This rock shaft has an arm 150 connected pivotally at 151 with a rod or link 1552 extending upwardly and carrying a tappet 153, which may be adjustable vertically along said link. This tappet engages the elbow lever 98, and is adapted to rock the same to engage the abutment 95 and move the vertical strip 87. The upper end of the link 152 is connected pivotally at 152 with one end of a. lever 154, fulcrumed at 155 on a stationary part of the machine and provided, at its other end, with an operating lug or knob 156 adapted to register with the upper end of the abutment 115 when the latter is in the position shown in Fig. 6. The term die is herein applied to the box-receiving parts carried by the slide 73, that is to say, particularly, to the back-plate 66 and the strips 86, 87, 99 and 105. The back-plate is supported in any suitable manner, for instance by means of a lug 66' (Fig. 13) resting on the upper end of one of the strips 69, and at- 66 we have indicated holes through which the attendant may insert his fingers so as to better grasp the back-plate when inserting or removing it.

The box A having been brought into the die while the latter is in the position indicated in Fig. 8, the core 38, which at the time of the bringing the box into the die is in contact with the inner face of the box bottom 36, in the same relative position as indicated in Fig. 11, is withdrawn therefrom toward the left, to the original position of the core as indicated by full lines in Fig. 1. The core 38 therefore is now clear of the path of the die, and the latter is free to move with the slide 71, from the position shown in Fig. 8 and indicated at a. in Fig. 6 at the left, to the position shown in full lines, at tne right of Fig. 6, and Fig. 9 illustrates an intermediate position which occurs shortly after the beginning of this movement, it being understood, however, that the movement of the die from the position Fig. 8 to the position Fig. 6 at the right, is continuous. In the initial or normal position, the folders 125 and 139 are in their inactive or retracted position; Fig. S shows the inactive position of the folder 125, see also Fig. 7, and the folder 139 is in its inactive position when the slide 138 is at the left-hand end of its stroke in the guides 137, that is when the F roller 143 is at one of the depressed end portions of the earn 144; Fig. 6 shows the folder 139 in such inactive position, and it will be understood that with the die in the initial position, Fig. 8, the roller 1 13 will be at the left-hand end of the cam 1 1 1, but the lever 1 1-0 and the parts connected therewith (slide 138 and folder 139) will be in the same position relatively to the die as in Fig. 6. As the die with the parts carried thereby moves to the right, from the position shown in Fig.

8 to that illustrated by Fig. 6, the cam 128, moving with the die, will by its engagen'ient with the roller 127, swing the arm 126, the rock shaft 117, and the folder 125, from the inactive position Figs. 7 and 8, to the active position shown in Fig. 9. The folder 125 thus comes close to the path of the open end of the box A, and folds inwardly, the portion of the strip 44 which extends vertically along the right-hand side 21. At substantially the same time, the action of the stationary cam 1 11 on the roller 1 13, as said roller rides up the incline shown at the left in Fig. 6, shifts the folder 139 from the in active position shown in Fig. 8 (in which it does not project to the right of the side strip 86). to the active position, Fig. 9. in which such folder projects to the right of said strip 86, and thus the left-hand vertical portion of the strip 4 1 is folded inwardly. Immediately thereafter, the upper and lower folders 135 come into engagement with the upper and lower portions of the strip 14, lying along the horizontal sides 21 of the box, and likewise fold these strip portions inward. The result ofthis folding operation is to bring that portion of the wrapping strip 4-1 which projects at the open end of the box, from a position perpendicular to the plane of the bottom 36, to a position parallel with said plane. It will be noted that the folders 125 and 135 do not share the movement of the die, that is to say, the box A carried by said die moves past these folders; the folder 139, however, moves with the die. The yielding mounting of the folders 135 at 131- is simply for the purpose of adjusting them accurately by the aid of the set screws 132, and said folders 135 are set in such a manner that the folder 139 will not come in contact with them, see Fig. 12. Before the folder 139 reaches the folder 125, the latter is swung out of the way, to the inactive position. as the roller 127 reaches the right-hand incline of the cam 128, see Fig. 7. All interference between the action of the relatively stationary folders 125 and 135 and of the relatively movable folder 139 is thus avoided.

This operation having been completed, and the die remaining in the same position, a pressure-plunger 157 is advanced into the box to fold the edges of the wrapping strip 1 1 which have just been bent into the same plane by the action of the folders 125, 135, and 139, into the box and against the inner surfaces of the four box sides 21. This plunger 157 moves in a direction parallel to the path of the core 38, and may be constructed and operated in any suitable manner, for instance as set forth in our earlier application mentioned above. While this plunger is within the box, as indicated in Fig. 19, the rock shaft 149 is operated to bring the two strips 87 and 105 toward the strips 86 and 99 respectively, it being underst od that. at that time the a u onts 95 and 1T8 in registry with the 1 nective operating members 98 and 155, as shown in i 6. The strips 87, 105 being moved as forth, will press the box lirmly against the plunger 157 and against the relatively stationary opposing strips 86 and 99, the plunger being mounted with suilicient looseness so that the pressure of said strips 87, 105 will be transmitted by the plunger 15 to the box sides 21 which he adjacent to the strips 86 and 99, respectively. The movable strips 87, 105 therefore constitute or issers to insure the proper adherence of the wrapping strip let at the open end. oil the box, both on the inner and on the outer surface of said box.

Preferably, after this pressure has been exerted. and when the pressers S7, 105 have been moved again to the releasin position shown in Fig. 6, the plunger 15'? is given a slight additional movement toward the box bottom 36, for instance to the position indicated by the dotted. line in Fig. .9, so as to re lease the plunger from the n pping strip 4., in case any glue should come between the lunger and said strip.

The subsequent operations may consist in expelling the box A from the die, as by means of an ejector 158, the operating mechanism of which may be of the some type as disclosed in the aforesaid application. Plunger and ejector may thereupon be moved in unison by any suitable means, to carry the box against stationary steps 15%), whereupon the plunger 15? will continue to move alone, so that the box A, being arrested by the stops 159, will be stripped oil the plunger 157 and dropped, for instance into a chute 160 leading to a su table support, such as a table or a conveyor (not shown), the box thus discharged being taken away manually or mechanically.

Fig 12 and 19 show the depth of the plunger 15'? as slightly greater than the width of the strip portion folded inside the box; the edge folded against the bottom 36 is in its entire width, in contact with the back plate 66.
