MAGAZIN E-WRAPPIN G MACHINE.

Application filed August 12, 1912, Serial No.

' To all whom it may concern:

known that I, DANIEL S. BAInn,of

of Toronto, in the Province of Canada, have invented certain new Improvements in Magazineof which the following Be it the city Ontario, and useful rapping Ma chines, is a specification.

This invention relates to mechanism for wrapping printed matter and the like for distribution, and my object is to devise apparatus which will roll up with a magazine a sheet of paper drawn from a web and seal the same.

I attain my object by means of apparatus which will grasp the magazine, and in some cases the wrapping paper, near the forward sides, and by a rotary movement roll up the same together until the magazine is completely wrapped, the wrapper sheet torn from the web and edge pasted down. firmly, and its accompanying drawings, in which F lgure l is a vertical section of a portion device and its operating mechanism.

In the drawings like numerals of reference indicate corresponding parts in the different figures.

In this machine I employ certain feeding, cutting and pasting devices which are well known in the art and need not be particularly described. Sufli of wrapping paper roller 2 and is fed forward by the feeding rollers'3 operated in 'anywell known manner.

I Specification of Letters Patent.

a previously gummed 8.

of magazines, to engage the ce it to say that a web are held in place at their lower ends by the Patented Jan. 4, 191

714,687. Renewed September 1, 1915. Serial No. 48.579.

From the lower feed rollers 3 the paper passes between the guiding and feeding rollers 4, as shown in Fig. The lower feed rollers 4 are geared together, as shown at the left hand side of Fig. 2, by means of the spur gearing 5, so that they may be simultaneously operated in any well-known. manner.

Intermediate the feed rollers 3 is placed construction. Paper cutting devices for partially severing the paper will be employed, intermediate the, roller 1 and the pasting mechanism, but no claim is made for such features, as the present invention lies the pasting mechanism 6 of any well known particularly in the means for actually performing the wrapping operations.

The magazines themselves are placed in a pile on th A slide 9 is adapted play backward and forward beneath the bottom of the pile magazines one its edge 10. The result of its that the magaat a time to the by one with reciprocatingmovement is zines are fed forward one front of the table 7. This plate is actuated by means of the rock'arm 11 which is fulcrumed intermediate its ends. end of this rock arm is actuated by means of the pitman' 12 connected with a wrist pin on the gearwheel 14 suitably journaled on the frame and actuated by the gear wheel 39 on the shaft 15.

he wrapping mechanism proper has as its basis the forks 16 formed on the spindles the bearings 18.

he forks are rotated through themedium of the pinions19 engaging the spindles 17 through the medium of suitable keys and keyways'. The pinions mesh with the gear wheels 20 fast on the spindle 21 journaled in. the brackets 22. Th carry racks 24! These racks are dr ven by meansof the cams 25 fast on theshaft 15, the lower ends of the racks being preferably provided with the anti-friction rollers 26. The racks links 27 said links being pivotally connected at their forward ends with the racks and at I ese splndles also the pinions 23 which mesh with the their rearward ends with the frame of the normal.

A "curs some little distance back machine. The upper ends of the racks slide in) the brackets 22.

By the constructions just described the forks 16 are given a rotary movement in one direction, the movement being then reversed and the forks returned to their original position. The forks'are also, as already described, capable of endwise movement. This movement is imparted to'them at the proper time by the following mechanism: At each side of the machine the rock arm 28 is fulcrumed intermediate its ends (see Figs. 4 and 2). The upper end of this rock arm is shaped like an ordinary engage a. grooved hub 29 on the end of one. ofthe spindles 17 The lower end of each rock arm engages one of'the cams 30 fast on the shaft 15 being provided with the antifriction roller 31 for this purpose.

On reference particularly to Fig. 1, It will be seen that when a magazine 32 is in the position shown indotted lines that the front edge'of the wrapping'paper lies on its upper surface adjacent the forwardside. The forks 16 have engaged between them the magazine at its forward side, also in some cases the edge of the At this moment the forks are rotated rolling up together the magazine and the wrapping paper until a complete cylindrical.roll is formed. j The web of wrapping paper is partly cut or perforated at such intervals that rather more than a complete turn of the wrappingpaper istaken around the rolled magazine, after the latter has been completely rolled up The pasted or gummed edge of the wrapplng paper thus contacts with the wrapper, and the-wrapper is thus secured about the roll. To insure a tight roll and the proper pressing of the contactwiththe roll I provi e the pressure bars 33 preferably formed as rolls journaled in the blocks 34 movable to and from the forks 16 in the guides 35. -These pressure bars are yieldingly pressed toward the forks by means of the springs 36 engaging the blocks 34 and the guides 35. The pressure bars thusmaintain a firm pressure on the roller as the wrapping proceeds while they readily yield to accommodate the increasing diameter of the roll as wrapping proceeds. One important result follows from this increasing diameter of the roll. Thewrapping paper is by the rotating roll at a greater speed than Consequently if it has been impressed with lines of weakness either before the web is placed inthe machine or as the paper is fed from the roll the part being about the roll is torn away from the rest "of the web. This tearing away ocfrom the to insure also asted edge in clutch shifter to' wrapping pathemselves to drawn forward forks, so that at the time the rolling is complete the now forward edge of the web is just approaching the wrapping position shown in Fig. 1. Of course, the rapid drawing away of the end of the web being wrapped round the magazine may be assisted or entirely caused by rotating the forks 16 with. a surface speed somewhat higher than that of the paper feed.

The completely wrapped magazine is ejected by means of the following mechanism: A kicker lever 37 is suitably fulcrumed at 54 on the frame of the machine with its upper end justbehind the position,

occupied by a completely rolled and wrapped magazine. At the proper instant this kicker lever is actuated to contact with the rear side of the wrapped magazine and throw the same forward out of the way of the succeeding magazine. This movement is accomplished by means of the pin 38 secured to the gear wheel 39 ,on' the shaft "15, which gear wheel forms part of the train actuating the magazine feed. A coil spring 40 is suitably arranged to retract the kicker as soon as its function has been performed. t should be mentioned that just before the kicker is actuated the forks 16 are being withdrawn from the wrapped magazine leaving the latter free to be ejected.

The forks 16 being very short, andtwo being employed operating from each end, the movement of engagement with and disengagement from the magazine is very much more rapidly performed than if a single fork were employed which would necessarily have to extend substantially from end to end of the forward side ofthe magazine necessitating a prolonged travel.

The use of two short forks, however, introduces a disadvantage which special mechanism is required to overcome. That is, the magazine has a tendency instead of rolling smoothly to buckleat the center between the forks, preventing the formation of a neat and well wrapped roll. To correct this tendency I provide an anti-buckling device, comprising a finger 41, adapted to engage the upper surface of the magazine just back of the surface of an imaginary cylinder containing the forks. This finger issecured to the spindle 42 journaled 0n the frame of the machine. The arm 43 is secured to the one end of the. end of the coil sprmg 44,-the other end of which is connected to a suitable stationary part and tends At the proper moment straighten out a arm 46 which by means with a pin 47 the arm 43. The rock arm is actuated momentarily by means of the cam 48 on the shaft of one of the rollers 3. Just back of this finger the magazines pass under of the slot 55 engages lowing restraining mechanism. One or more fingers 49 with bent ends 50 are secured to a shaft journaled on the plate 8. A rock arm 51 is secured to the shaft and has its upper end bent over the shaft of one of the rollers 3 so as to be engaged by the cam 52 thereon, which bent end is moved forward at the proper time by the cam to give a rearward kick to the lower end of the said rock arm.

The result is that as each bottom magazine is fed forward the one next above is given a backward kick which effectually prevents it following beneath the bent spring tinge-r53. This isintended to keep back all magazines except the bottom one but'as it must be more or less yielding to suit inequalities in the binding of the magazines it is not sufiicient in itself without the addition of the positively operated fingers 49, The next magazine above as it 49 forward sequently the rock arm 51 is position for its by the cam 52.

From the above description it will be seen that I have devised a machine which will descends pushes the fingers brought back in form a neat tight roll of'any magazine, or is particularly adapted 1 to magazines of some weight and thickness the like, and which which cannot be folded.
