DEVICE FOR SETTING INVISIBLE EYELETS.

Refiled for abandoned application Serial No. 394,090. filed July 6, 1920, and in Canada June 10, 1924. This application filed June 2, 1925. Serial No. 34,361.

My invention relates to devices for setting blind or invisible eyelets and more particularly to that class of such devices having a restricted setting shoulder adapted to pass 6 through a punched hole in the outer layer of a plurality of layers and clench an eyelet upon the inner layer or layers.

The devices generally in use now'tor setting invisible eyelets belong to the foregoing 10 class. This is particularly true of the shoe manu'lactm'ing industry in which these, dc vices have been largely developed; forinvis ible evelctting has been used to a very large extent in shoes of all kinds. In the setting of invisible eyelets in shoe uppers, for instance, a holeis first punched through all the layers of the upper by a suitable tool, after which an eyelet is presented by a lower set to the inner side ofthe upper and forced into the punched hole and against an upper set having a restricted setting shoulder. As the eyelet pushed upwardly on the upper set by the lower set, the layers of the shoe upper are forced upwardly by the end of the barrel of the eyelet, and the outer layer is forced over the restricted settin shoulder and into engagement with a permanent or secondary shoulder above. Meanwhile the scored end of the barrel of the eyelet is split into a plurality of tongues by the restricted setting shoulder and these are turned over by the shoulder upon the layers of the upper which remain below the shoulder and there clenched, so that the eyelet is clenched upon the inner layer orlaycrs of the upper in register with the hole in the outer part of the upper.

la the development of these devices in the shoe manufacturing art, it was early discovered that the distance between the setting shoulder and the secondary shoulder above it must be just sufficient to accon'in'lodate the outer layer of the upper and no more norno less. It the space was insufficient the prongs of the eyelet were pushed through the outer portion (generally the leather) which made a defective setting; if the space was too great, other layers of the upper, in addition to the outer layer, were forced over the setting. shoulder and the eyelet was clenched upon the wrong layer.

This necessitated the making of sets varying in dimens on between the setting shoulder and the secondary or permanent shoulder in order to suit various thicknesses of leather, and required the setting tool in the cyeletting machine to be changed from time to time to conform to Variations inthe thickness of the leather; all of which consumed time and labor and hindered the progress of the uppers through the factory.

To obviate the foregoing difficulties the secondary shoulder above the setting shoulder was made adjustable so that the distance between the two might be regulated to suit different thicknesses of outer or leather parts. That part of the setting device between the two shoulders may be either straight or recessed; but the latter is preferable because it seems to facilitate the flipping of the outer part over the setting shoulder during the setting of the eyelet. A. setting device of the recessed type is shown in United States Letters Patent No. 1,112,643 issued to L. Muther, October 6, 1911-, and in Letters Patent No. 1,110,258, issued to .me September 8, 1914, is shown the Muthcr setting device with an adjustable nut or secondary shoulder above the setting shoulder. By turning the nut the distance between the setting shoulder and the lower face of the nut may be varied to suit the thickness of the leather or outer layer of the upper. The use of the setting device shown and described in the latter patent referred to, requires adjustments from time to time, depending upon the variation in thickness of the leather in the shoe uppers in which the eyelets are being set, but where the leather runs of uniform thickness, one adjustment is sufiicient.

In some cases, however, it has been found that the leather used for shoe uppers is not uniform in thickness and varies in the same upper showing a gradual increase or decrcase in thickness from the lower edgeof the upper to the top edge along the eyelet row. To secure the best results on such upljiers the distance between the setting shoulder and the secondary or adjustable shoulder should be changed to correspond to the gradual variation in the thickness of the leather which, of course, is impracticable where the nut or other adjustable member is fixed in adjusted position.

The object of my invent on is the pro eyelet setting the thickness of the leather or outer portion ogt theshoe upper in which the eyelet is being set.

A further object oi. the invention is the provision of means which is etlicient, positire and accurate in operation at all times.

Other objects of the invention will be more specifically pointed out and described lnueiiia'ttcr.

My invention contemplates a blind eyelet set provided with an adjustable shoulder above the setting shoulder and movable longitudinally of the setting member, with means engaging the upper before the eyelet is clenched, for regulating the distance between the setting shoulder and the adjustable shoulder, and means "for locking the adjustable shoulder in its adjusted position just prior to the clenching ot' the eyelet so that iii the leather increases or decreases in thickness, the adjustable shoulder is moved away tremor toward the setting shoulder to correspond with said increase or decrease in thickness. In consequence, when the eyelet is being clenched, the space between the setting shoulder and the adjustable shoulder is just tqual to the thickness of the leather outer part, whatever that may be, and the leather or outer part only is permitted to go over the setting shoulder thereby insuring the clenchii'i'g of the eyelet at the desired point upon the lining or inner layers in register with the hole in the outer part.

in the drawings illustrating the pretcrred (IlllJOtlllllQIlb of my invention, Figure 1 is a side elevation of a combined punch and set of the term shown in the Muther patent hereinl'ietore referred to, with an adjustable shoulder constructed and operated in accm'dance with my invention; Fig. 2 is a similar elcvation on an enlarged scale of the same showing the punch at the completion of the operation of punching a hole through the various parts making up a shoe upper, the adjustable shoulder being in an unlocked position; Fig. 3 is a view similar to Fig. 2 except that the punch has fed the upper to the setting point in position to receive the eyelet on the lower set with the adjust-able shoulder in a locked position; Fig, 4 is a detailed view in perspective of the adjustable shoulder and the member carrying the same; Fig. 5 is a view in perspective of the lever for locking the adjustable shoulder in its adjusted position just prior to the clenching oi the eyelet; Fig. 6 is a view in perspective of the bracket; and Figs. 7 to 12 inclusive are views showing the various stages in the operation of setting eta blind eyelet in a shoe upper.

In the drawings I have shown my invention applied to a blind eyelet setting device of the Muther type and as adapted particularly for use in an eyeletting machine made in accordance with United States Lettcrs Patent No. 636,035, issued to Perley R. Glass, October 31 1899', but it is to hennderstood that my invention is not to be limited to the application herein shown and described but may be applied to blind eyelet setting devices of various other constructions adapted for use in other eyeletting machines, some of which, possibly, may require slight changes which would, however, be apparent to one skilled in the art.

Referring to the drawings, 15 designates a punch bar furnished with a threaded bore in; its lower end to receive a blind eyelet setting device of the Muther type, having a threaded shank 16 adapted to be inserted within the threaded bore of the punch bar and a flange shoulder 17 adapted to engage the end of the punch bar. The device has a central longitudinal bore 18 and end 19 is formed for punching a round hole. The surface of the device expand-s upwardly to form a restricted setting shoulder 2-0 above which a contracted portion or recess 21; and above that the device is straight to the flange 17. The device, because one of its functions is to punch the hole in which the eyelet is set, is commonly termed a punch. although it has two functions, one of punching the hole and the other of acting in conjunction with a lower set 22, for clenching the eyelet. Substantially all of the foregoing is old and constitutes no part of my invention.

The novel features of my invention reside in the adjustable shoulder on the punch for detern'iining the distance between the setting shoulder and the lower fa ot the adjustable shoulder, in the means .vhereby the position ofthe adjustable shoulder above the setting shoulder is determined by the thickness of the leather at or near the point where the eyelet is to be set and in the means for locking the shoulder in position atttr it has been adjusted and helore the eyelet is clenched.

in the embodiment of my invention shown in the drawings, I provide an adjustable shoulder in the term of 'a ring 30 having a central circular aperture 31 to receive the body of the punch and the ring 80 is secured to or made integral with a carrier block 33 in olliset relation thereto. The carrier block is provided with an upwardly extending spindle 36 which passes loosely through a block 37 which is partially inset at 38 in the punch bar and secured thereto by any suitable means. On the spin-- dle 36 between the carrier block 3 and ti e block 37 may be mounted a helical spring 40' for maintaining the carrier block, and therefore the adjustable shoulder 30, in a loo 1 its ill lowermost position at all times. The spindle 3b is locked within the block 37 by the following means. A spring 41 is secured to the outer face of the block 37 by a screw 42 and in the end of the spring mounted a long stud 43 which passes through the block 37 and enters a longitudinal. recess 44 cut in the spindle 36. The spindle is thereby locked against removal from the block 37 but has a free longitudinal movemeut equal to the length of the recess lrl. To remove the spindle 36 from the block 37 the spring 41 is pressed to the right (referring to the drawings. Figs. 1-3) there by withdrawing the end of the stud 43 from the recess 44.

For regulating the elevation of the ad justable shoulder 30 above the setting shoulder I provide means adapted to engage the material. in which the eyelet is being set, said means being adjustable to secure a proper position of the adjustable shoulder during the setting of the eyelet. Various means mounted in the carrier and adapted to engage the material being operated upon may be provided and one such means is shown in the drawings comprising a screw gauge 45 threaded vertically through the block 33 and having a round head 46 adapted to engage the material. By turning the screw gauge in one direction or the other the carrier is adjusted in vertical position with relation to the material and thereby the adjustable shoulder 30 is moved nearer to or further away from the setting shoulder. As will be apparent. this adjustment is accomplished when the punch descends to punch the hole for the eyelet in the material, and this operation will be explained in detail hereinafter.

After the adjustment has been made at the punching point, it is. of course, necessary that the adjustable shoulder should be locked in its adjusted position before the eyelet is set in order to prevent any but the outer layer being pushed over the setting shoulder by the advancing eyelet. Various forms of means for locking the carrier in its adjusted position ma be provided and one form comprises the ollowing means: The block 37 provided with a central transverse bore 49 which intersects the vertical bore in which is mounted the spindle 36 and in the bore 49 is inserted a cylindrical lock 50 having cut away portions 51 on opposite sides thereof and a hole 52 theretln'ough. When the lock 50 is in position within the bore 49 the spindle 36 passes through the hole 52 which is slightly larger than the outside diameter of the spindle. If the lock be turned, however, the portions 53 of the lock bind against and grip the spindle thereby locking it against longitudinal movement. For operating the lock a suitable lever 55 may be provided which may either be attached to the lock or made an integral part of it, and for operating the lever I utilize one of the movements of the eyeletting machine. y

In the machine of the Glass patent hercinbefore referred to, the punch is carried on a movable head which, after the material is punched, moves laterally to the setting point, the punch remaining in the material and carrying it with it. This movement I utilize in the following manner for o ')er:1ting the locking lever 55. The upper end of the lever 55 has a hole 56 adapted to receive the hooked end of a rod 58, the other end of which passes loosely through a bracket fastened to a fixed part 59 of the frame oi the machine by a screw 61. The bracket 60 has a longitudinal slot 62 through which passes the screw 61 and this slot permits the bracket 60 to be adjusted along said rod The rod at its free end is provided with a head 64 and on the rod between the head 64 and the bracket 60 is loosely mounted a helical spring (55 which is not under compression when the punch is at the punching point. As soon, however, as the punch bar moves from the punching point to the setting point; that is, from right to left referring to the drawings, the rod 58 is carried in the same direction, thereby compressing the spring 65 which compression results in throwing the locking lever 55 to the right and locking the spindle 36 within the blocic 37 and the adjustable shoulder 30 in its adjusted position. By varying the fixed position of the bracket 60 the point at which the locking takes place can be varied to some extent between the punching and the setting positions with this qualification, that the adjustable shoulder must be free to move at the punching point and must be locked at the setting point.

In order to disassemble the rod 58 from the bracket 60 when desired, the former may be flattened at 67 and the latter may be provided with an open slot 68 sutliciently wide to accon'imodate the flattened portion 67 but not the rounded portion oi. the rod To separate the rod from the bracket, the former is moved in the hole (59 in the bracket until the flattened portion 67 registers with the slot 68 when that portion may be moved out of the slot and the separation RCCOITIPliShGCl.

In operation, my device works as follows. In Figs. 7 to 12 inclusive of the drawings I have shown various stages in the operation of punching a hole and setting a blind eyelet therein from the initial position of the machine to the completion oil? the setting op eration. In these figures 22 designates the lower set, 70 a spindle centrally disposed therein and retractable, being held in an upward position by a light spring, not shown, 71 an eyelet on the lower set con tralized by the spindle and 72 a work-plate. lhe lower set and spindle, together with the \vorloplate, punch ha and general form of the llluther punch herein shown are a l old and well known, both in construction and operation. The parts operate in the same manner with the exception of the operation of my adjustable shoulder and itsattendant mecoanism.

in Fig. 7 is shown the initial position of the various parts before the machine is started. Upon the work-plate is laid the material which is shown as oeing made up of three layers, an outer layer 73, an intermediate layer 74- and a lower layer 75.. suming the material to be an ordinary shot upper, the outer layer 73 would be the leather or outer part of the shoe upper, he intermediate layer 74. would be the lining and the lower layer 75 would be the facing. Sometimes additional layers are used, but as a rule the shoe upper is made up of three layers. the leather generally being much thicker than either the lining or the facing. in this view (Fig. 7), the punch is shown in a raised position above the material. with the adjustable shmilder held in a downward position near the setting shoulder 20 by the spring 40. The lower set 22 and spindle 70 are in a lowermost position underneath the opening 80 in the work-plate and in position to receive an eyelet from the raceway.

llpon be starting of the machine, the punch bar 15 descends into the position shown in Fig. 8, the punch punching a round hole through all the layer of the upper. its the punch descends the round head if of the screw guage l comes in contact with the leather 73 stopping further downward movement of the carrier 33 and causing the adjustable shoulder to remain still while the punch continues its downward movement until it engages the work-plate 72. After punching the hole, the punch bar then releases slightly to disengage the end of the punch from the work-plate and the punch bar is fed from right to left toward the opening 80 in the work-plate; the end of the punch remaining in the hole and carrying the shoe upper with it into the posi ion shown in the next figure.

In Fig. 9, the punch has reached the setting position directly over the opening 80, the punch still remaining in the hole in the upper with the head of the screw gauge l5 in engagement with the upper surface of the leather or outer part. During the movement of the punch from the position shown in Fig. 8 to the position shown in llig. 9, the carrier and adjustable shoulder have been locked in position through the medium of the rod 58 and spring 65, and the point at which the locking occurs may, of course, be regulated by adjusting the bracket 60. During the movements of the punch, as illusevant? trated in Figs. 8 and 9, the lower set 22 has taken an eyelet 71 from the raceway (not shown) and has gradually moved upwardly into the position shown in Fig. 9.

After the punch has reached the setting point, the lower set continues to rise and as the spindle 70 engages the lower end of the punch and the lower set continues to rise, the yelet is forced upwardly and the end o't its barrel enters between the punch and the ma terial and then encountering the enlarged surface of the punch, the end of the barrel of the eyelet is broken along scored lines into a plurality of prongs. As the eyelet conti nues on its upward movement these prongs tend to push the material of the shoe upper upwardly over the setting shoulder until the upper face of the leat-hen or outer part engages the lower surface of the adjustable shoulder 30. The space between the ting shoulder and the lower face of theiuljustable shoulder being just su'liicicnt to accommodate the leather part 73, the lini-i'ig 7d and facing E5 of the upper remain below the setting shoulderand the prongs of the eyelet are then turned over by the setting shoulder upon the lining and there clenched.

in Fig. 10 the ariou parts are illustrated in the position attained whenv the clenching of the eyelet is halfcompleted. The setting shoulder is so formed that it turns the prongs of the eyelet over in a curve similar to the curve of a breaking wave so that the ends of the prongs curve downwardly, as shown in the figure, and this movement eontinues until the lower set has reached the end of its upward movement and the clenching of the eyelet has been completed.

in Fig. 11 the parts are shown in their various positions atthe completion of the setting operation, the eyelet having been clenched upon the lining part while the outer or leather part was out of the way, above the setting shoulder. From this point the lower set descends to its initial position and the punch bar rises, withdrawing the punch from the material and then returns to its initial position preparatory for a repetition of the operation. In its return to its initial position the tension of the locking lever 55, due to the spring 65, is released, and whenithe punch bar has reached its initial position, the carrier block 33 is unlocked.

Fig. 12 is a view of the completed work showing the blind eyelet clenched upon the lining in register with the hole in the leather part.

As a general rule, in shoe uppers the thickness of the lining and facing combined is uniform so that after the screw gauge has been adjusted no further adjustment is necessary and thereafter the adjustable shoulder is automatically adjusted by the material itself. It is immaterial, therefore,

all)

whether the thickness of the leather or outer part increases gradually or suddenly; the adjustable shoulder takes care of the variation in thickness in any event. After the machine has been adjusted in any one factory, any further adjustments are generally unnecessary for a very long time, and the time now consumed in making various adjustments in an attempt to suit various thicknesses of leather is eliminated. Be cause my device takes care of gradual variations in thickness in the same upper, which graduation it is impossible to take care of in the devices now in use, uniform and perfect setting of the eyelets can be secured at all times.
