' and securing the wrapper by crimping or bending the ends of the wrapper inward upon themselves whereby the end portions of the article or package, except at the extreme edges, are exposed to view.

The inventionis especially applicable to what are termed coin packages in which a pile of coin are secured in a package by suitably crimping the projecting ends of the wrapper; which facilitates the handling of the coin, the contents being visible at eachend of the package.

One of the objects of the invention is to provide in a machine of this charabter, an improved form of bending finger or crimper; and also to provide an improved form of means for controlling the operation of the crimper whereby it will automatically accommodate its operation to the different diameters of coins.

In the accompanying drawings Figure 1 is a plan view of a portion of a machine embodying my invention. Fig. 2 is a similar view showing a part only of the mechanism shown in Fig. 1. Fig. 3 shows in end elevation, parts shown in Fig. 1. Fig. 4 is a similar view with the parts in different positions. Fig. 5 is a view similar to Fig. 4 but enlarged, with the parts in still another position. Fig.6 shows in perspective the crimping finger in the operation of crimping a wrapper on a coin package, and Fig. 7 is a section taken on the line 77 of Fig. 6.

The coin package denoted generally by 10 is supported between three parallel rollers 11, 12 and 13;

and. the distance apart of these rollers is made variable to accdmmodate different sized coin, that is different diameters of the coin packages. The roller 11 has a journal 14 at each end by which it is rotatably supported in hubs 15 but eccentric'therewith. The hubs are arranged to oscillate in bearing portions of upright sup ports'lfi and 17, whereby such rotation ofthe hubs Wlll cause a movment bodily of the roller 11. The roller 12 is similarly mounted, having journals 18 at each end that are rotatable in hubs 19 in eccentric positions. The hubs 19 are supported to oscillate in the side members 16 and 17, whereby such movement of the hubs will cause a movement bodily of the roller 12.

The third roller 13 is movable to and from the rollers 11 and 12 by means of journals 20 at each end that are each rot-stably carried by a T-shaped irame 21. The T members are in duplicateat each end of the mechanism as shown in Fig. l, and a description of one will answer for both. This frame 21 has its portion 22 slidable in a guide box 23. The frame 21 is caused to oscillate by means of a lever 24 pivoted at 25 on the frame member, (16 and 17,) which lever is swung in one direction from a cam member 26, the lever being held against the cam by a spring 27 which serves to swing the lever in the other direction. The frame 21 is adjustably connected with this lever 24 by means of a nut 28 slidable.

in a slot 29 of the member 22; and adjusted therein by means of a screw 30 rotated by handle 31. A pin 32 on the nut 28 operates in a slot 33 in the lever By this means the oscillation of the lever by the cam will serve to reciprocate the frame member 21, (at each end) and thereby the roller 13, moving it forward and from I the rollers 11 and 12. The rollers 11 and 12 may also be given a movement toward and from each other, as the roller 13 is adjusted, to accommodate for various diameters of coin packages, as indicated in Figs 3 and 4.

Y The hub 19 has an arm'35projecting therefrom, between which and one end of the frame 21 is pivoted a link 36. The hub 15 has an arm 37 connected with the opposite portion of the frame 21 by a pivoted link 38. By this means the sliding of the frame 21 will rock the hubs 15,

and 19-, and thereby cause the movement bodily of the rollers 11 and 12 moving them'toward and irom the roller 13. This will produce a mutual approaching movement of the three rollers when the frame moves in one direction, and a mutual receding movement of the rollerawhen the frame moves in the opposite direction.

It will be observed that during one half the revolution ofthe cam 26 its concentric portion will engage the le; ver 24 and retain the rollers in the closed position permitting the operation of the crimping mechanism.-

-. The crimping operation is effected at each end of the V package by duplicate means; each comprising afinger or crimper 40 carried by a sleeve 41 that is rotatable on a bent rod 42 and given a slight yieldrble movement thereon, by means of a spring 43 connected between'a pin 44 fast on the rod 42, and an arm 45 secured to the I sleeve 41. The finger or crimper 40 extending from the sleeve 41 is first bent downward at 46, and then bent transversely or sidewise at 47. In the operation of the finger, it is first swung on the axis of the sleeve 80 that the extremity will entirely clear the projecting.

edge of the wrapper, as indicated in Fig. 5. The crimper is given an endwise movement, as indicated in Figs. 1 and 2, whereby its bent portion 46 will turn crimper to engage the inner face of the wrapper and complete the operation of doubling the, wrapper upon ioo itself. The next operation is to cause a reverse swing of the crimper on the axis of .the sleeve, to withdraw the extremity of the crimper from engagement with the wrapper; and thereupon. the crimper is bodily'moved 5 to its former position, to permit the removal. of the package and another package'to be-placed in position for operation. One means for automatically effecting such operation is shown in the drawing, wherein each .rod 42 is secured to a nut member 48 that is supported .to reciprocate by means ofsleeve portions 49 and 50, slidable. on shafts 51 and .52 respectively. These shafts are rotatable in .the side members 16 and 17. Between the shafts 51 and 52 is lqcated 'a screw member 53 having journals 54at each end eccentrically supported in hubs 55, that are rotatable in the side members 16 and 17 respectively. The swinging of these hubs will shift the screw shaft 53 into and out of engagement with thread portions 56 on the nut members 48; whereby the rotation of the screw will cause the not members to travel from the positions shown in' full to the position indicatedin broken lines. v i The shaft 51 is rotated by any-suitable means, such as a pulley 57, and serves to drive the screw shaft 53 by means of friction wheels 58 fast on the shaft-51 that will engage friction wheels 59 fast on the screw 53, when the latter shaft is shifted on its eccentric supportto cause its screw portions83 and 84 to engage the nut portions 56. But upon movement'of-the shaft out of position of engagement with the nut member,'the friction wheels will disengage. This shifting of the screw shaft into and out of engaging position is effected at each end of the machine from'the operation of the lever I 24 by means of connecting-links 60.and 61, thelatter being pivotedto an arm 62 fast on the hub member 55.

The rod 42 carrying the crimper 40 is secured to the nut member 48, and when the lever 24 is in the position shown in Fig. 3, in whichthe three. rolls 11, 12 "and l3 have been caused to approach and engage the coin package,-the nut members beingbrought into engagement with the screw, will cause the crimpe'rs to be advanced as indicatedin Fig. 1 to the broken line position. But by the time the crimpers have traveled a l sufficient distance to crimp-the wrapper, the lever 24 is released by the cam and moved upwardby the spring, which will throw the screw 53 out of engagement with v I the nutmembers. At-this stage a coil spring 63- on the shaft 52 between the sleeve 50, that has been compressed ,7 during the travel of the sleeves, will react andreturn the nut members and crimpers to their former positions. This movement is limited by adjustable steps 80' whose threaded bore engages-threaded portions 81 and 82. of the shaft 52." a L Means are provided for swinging the crimper on the axis of the supporting sleeve, upon being advanced by .thenut member and causethewrapper to be doubled -inwagd', .and.,also; for. swinging the fingeriinward or 1 iysssr seithe pp at e-endst e i p s P- n st qmbeter t ei imr r rimped por- .e observed passes around. a huhtifi r hatis eccentrically pivoted. on a journal 67, projecting from the nut mem'- 65 her 48... The extending portion of the rod projects *lloope along the nut member and has its extremity secured to a coil spring 68 fast on the member 48. A link 69 is pivoted between the frame 21 and an arm 70. fast on the hub 66; whereby the swinging of the frame will rotate the collar on its eccentric bearing moving the 70 rod outward from the member 48. This lattermotion will swing the crimper on the axis of its sleeve and move its transverse arm toward or from the periphery ofthe projecting portion of the wrapper, as indicated in the positions of these members shown in Figs, 3 and 7 5 4. By this arrangement, the adjustment of'the nut connection between the lever 24 and the frame 21, vaying the path of movement of the frame 21, will, through the link 69, varythe position'of the transverse arms of the crimpe'rs. 8O 7 Additional means are provided for swinging each crimper on its axis upon the crimper being advanced to engage the paper, and which means will swing the crimper inward or away from the wrapper at the conclusion of its operation before returning it to its former position. A cam member 71 is pivoted on the member 48, at each end and has an arm 7 2 pivotally connected with a portion of the link member 61, that is made somewhat U-shape. The round portion 73 of the cam member normally engages the rod 65, swinging the rod on its loop axis on the hub 66, retains the crimper with its extremity offset from the wrapper, as shown in Fig.

. 5. But as the lever 24 moves downward, it first brings the rollers into engagement with the package and also causes the screw member to engage the nut member and rotate the latter 'through the friction driving wheels. During this operation, the flat portion 74 of, the eccentric 71 permits thespring 68 to swing the rod 65 to the positions shownin Figs. Sand .4 thereby swinging the crimper to bringitsiextremity intoengagement with the inner face of the crimping portion of the vwrapper, to complete the crimping operation But upon the return stroke-of the lever 24, the cam 71 will first swing and rock therod 65 to move the crimper arms away from" the paper, before the screw memberis disengaged from thenut members 48 permitting the I spring 63 to return. the nut members to their former position.

Adjustment for different lengths of packages is pros vided for by means of theshiftable stopsBOL: At'each release of the; nut members 48 from the screw. portions 83 and 84 of the member 53, the spring.63"will move the nut members in opposite directions,.until they engage the stops 80. At each engagement, of the nut members with the said screw portion they will advance l. 1 5 a certain distance that is constant,. that'is fora'lccrta in number of threads. This distance will be fronrthea' adjustedlposition of the stops toward each other, and therefore this adjustment of the stops will determine the range of operative positions of the crimpers. Mov- 7 ism organized and timed to move the finger bodily-toward i the end of the package and swing the end portion of the arm outward to crimp the wrapper, to next swing the arm in the reverse direction bringing its end away from the crimped portion, and to next cause a return movement of the finger to its former position. l
