(Cl. 93—-5) My invention relates to crimping the ends of paper wrappings or tubes for rolls of coins and other cylindrical objects. Primarily it provides a device capable of crimping rapidly, securely 5 and uniformly, It relates especially however to devices for crimping ?lled coin containers fed to it by hand, and from this aspect it comprises a crimper head, a carrier adapted to receive the ?lled container IO from the hand of the operator and present the same to the crimper head, and associated mecha nism to operate the carrier and the crimper head and to operate these parts in proper time rela tions. Preferably too the arrangement is such that the whole operates at whatever rate the operator is able to handle the containers. The carrier servesseveral purposes. First, it relieves the operator of the duty of holding each article of the work during the actual crimping‘operation, 20 thus saving possible injury to his hands and en abling him to devote his time to feeding and any other operations that he may be called on to per form simultaneously; second, in its preferred form, it enables crimping to be done simulta neously with feeding, neither of these operations therefore delaying performance of the other; third, it places each and every article in the proper position with respect to the crimper head and. permits the use of a device that holds each package securely against rotation during crimp~ ing, thus assuring proper crimping in all cases. Preferably the arrangement is such that the carrier holds the package at rest at the crimping station and the crimper' head is brought to the package to make the crimp. Further my inven tion comprehends also an improved crimper head adapted to make a crimp faster than crimper heads heretofore used; while this part of my in vention is adapted for use with machines wherein 40 the package is held by hand conceivably, it is especially adapted to machines wherein they crimping is entirely a machine operation since it enables the crimping to be done at the higher rates of which complete machine operation is ., . capable. Other features of my invention appear hereinafter. In these respects my invention is not limited to hand fed machines. Also my in-‘ vention is not limited to containers for coins as will be apparent; but can be employed to crimp other containers and wrappers also. The accompanying drawings illustrate the pre ferred form of my invention as applied to a ma» chine for crimping ?lled coin packages already crimped at one end. > ‘ tion of the machine. Fig. 1 is a sectional eleva Fig. 2 is a detail, drawn to a larger scale, to illustrate particularly my im proved crimper head. Fig. 3 is a sectional ele vation of the upper portion of Fig. 1 illustrating the crimping operation. Fig. 4 is a horizontal section about on the line IV—-IV of Fig‘. 1. Fig. 5 5 is a horizontal section about on the‘ line V-—V of Fig. 1. Fig. 6 is an elevation, partly in section, looking from the left of Fig. 1. Fig. 7 is an ele vation and Fig. 8 is: a plan View of my improved. crimper head. The crimper head i is arranged to be recipro cated toward and from the coin rolls as these are held by the carrier 3. The carrier is provided with a number of pockets 4 (in the present in stance, six pockets) to receive the coin rolls (one 15 roll per pocket), and is movable in such a manner as to carry the pockets substantially successively to the crimping station position of Z in Fig. 1, whereat the crimping is done. Preferably it is mounted for rotation about an axis 3'! for this 20 purpose. The carrier is so disposed that at least one pocket is exposed for hand feeding at what may be called the loading station (at the left hand side in Figs. 1 and 4). Preferably too the carrier is moved intermittently, step by step in carrying the pockets from the loading station to the crimp ing station; as a result the empty pockets are held at rest momentarily at the exposed position for ready loading and also the crimping mechanism is thereby permitted to be simpler than it would be if the crimping were done while the carrier is in motion. As appears at 2 in Fig. l, the work to be handled by the machine illustrated com prises coin-?lled paper tubes, the tubes being crimped previously at their bottom ends (on which they rest in the carrier) and projecting somewhat above the coin stack at their upper ends for crimping in the present machine (as indicated in broken lines in Fig. 1). The asso ciatcd mechanism hereafter described drives the carrier and also reciprocates the crimper head, so that the‘ two operate in proper time relation. Arrangements can be made for the automatic discharge of the crimped rolls from the carrier; e. g., by arranging for the fall of each crimped roll from its pocket as the pocket returns from the crimping station to the loading station as later described. Broadly speaking, the crimper head I may be of any type suitable for the purpose. For ex~ ample, it can be that rotary crimper head here tofore commonly used which comprises a simple cylinder 8 to closely encompass the end of the wrapping, one or two crimper members each hav ing a curved under surface to receive the edge 2,110,685 2 of the paper and roll it back on itself internally of the wrapper (e. g., a wire or wires 9), and a bridge or cross bar 5 at the same end of the cylinder by means of which the cylinder is car ried. A driven shaft iii connected to the bridge or cross bar 5 serves to support the crimper head and rotate it rapidly as the head is pressed against the roll or as the roll is pressed into the head. I have found however that these prior crimper heads are not capable of making as satisfactory 10 crimps as I desire when pressed down against the tube end sufficiently rapidly to take full ad ously and a crimp can be made by simply press ing the crimper head to a tube. The crimper frame 2i is supported vertically and reciprocated by mechanism including the connecting links 28 as later described in more detail. Preferably the carrier 3 consists of a disc-like Si vantage of the high operating speed of which machines of my invention are capable; at least not unless the head is rotated at unnecessarily member, the pockets 4 (of suitable size and shape in cross section to receive the coin rolls stand ing on end) are pierced completely through it, and the carrier rests against a frame plate 34 which thus serves to close the pocket bottoms and pro vide a support for the rolls during crimping; this permits ready discharge of the rolls after crimp ing, the plate 34 being cut away at some point 35 traveled by the pockets in returning from the 15 high speeds; and at such high rotary speeds there is some tendency for the crimper head to destroy the integrity of the paper. Preferably therefore I provide the crimper head with a circumferen tially-long surface or a series. of surfaces I I curved upwardly and inwardly to engage the projecting end of the wrapper continuously or at many points around substantially the whole of its circumfer ence, so that the end of the tube is engaged and turned inwardly at a corresponding number of the parts of its circumference rather than only at one or two points as heretofore. This or these surfaces Ii need not be shaped to turn the end of the tube back toward the opposite end of the roll (as do the crimper members 9) ; it is su?icient if this or these surfaces iI will turn the tube end inwardly for, say, about 90° as shown in Figs. 2 and 7. If the crimp is to be a rolled crimp as illustrated in Fig. l, a few crimper members. 9 (say, two) having wrapper-engaging surfaces suitably curved for this purpose as heretofore will suffice to turn the tube end back to effect the roll of the crimp. In so far as these surfaces of the crimper members 9 are co-extensive with 40 the surface or surfaces I l the two may be at about the same level; usually however I set the crimper members 3 so that their working surfaces project a little from the surface or surfaces. II, i. e., are disposed to strike the end of the tube slightly in 45 advance of the surface or surfaces I i. Preferably however the end of the tube is supported extern ally as by the internal cylindrical surface of the member 3 as before. Conveniently therefore the crimper head can consist, as shown, of a mem 50 ber 8 bored to closely encompass the end of the coin tube or wrapper, this encompassing internal cylindrical surface blending into the curved sur face or surfaces I I (Figs. 2 and 7) and the mem ber being slotted at 52, say at two diametrically 55 opposite points, to receive the crimping members ii which may be like those heretofore employed. Preferably one or two holes. I3 are provided (Figs. '7 and 8) to permit the escape of any fibers that may be worn from the wrappings or tubes during 60 the crimping operations. In order that the crimper head I may recipro cate toward and from the carrier 3, its support and driving shaft is mounted in a crimper frame 2! which, in turn, is mounted for reciproca the machine frame ‘.23. Preferably it is 65 tion siidingly mounted on the rotating shaft 22 which serves to rotate the shaft ill; the upper and lower ends of the shaft 22 may be supported by upper and lower parts of the machine frame 23, and 70 have fastened to its upper end a sleeve 24 with which a gear 25 is slidingly keyed, the latter gear meshing with a gear 26 fastened to the crimper shaft it. The shaft 22 may be driven continu ously, say by a motor 2? carried by the machine 75 frame; thus the crimper head I is- rotated continu crimping station to the loading station, say at a point where the pockets come to rest momentarily due to the intermittent movement of the carrier; the rolls are thrust from the carrier through this cut; if the carrier and plate 34 are substantially 20 horizontal, gravity will serve to discharge the rolls. A chute 33 below the cut 35 will serve to direct the rolls to a receptacle. The periphery of the carrier disc 3 is pierced opposite each of the pockets, as illustrated at 32, in order that the 25 clamp 33 may engage the rolls to keep the same from turning during the crimping operation as later described. The carrier 3 is driven by its shaft 31. Preferably all the operations are controlled by 30 a single cam shaft or controlling shaft 38. Also, preferably, the operation of the machine is put under the control of the operator so that he may advance the carrier 3 as rapidly or as slowly as he may wish. To these ends the driving shaft 35 22 drives a single-turn clutch 39, mounted on shaft 38, through the worm 4i) and worm wheel 4|; the latter is rotatably mounted on the cam shaft 38 but is adapted to be engaged with the shaft by the clutch. This clutch is controlled by 40 a link 42, connected say to a foot pedal through the link 43; single-turn clutches are well known, and no description of that here employed is needed therefore; as the operator depresses the foot pedal and link 43, the clutch operates to-en gage the worm wheel 4! to the cam shaft 38 for one complete revolution of the cam shaft and then break the driving connection again so that the cam shaft 38 comes to rest unless the operator has held the pedal down or depressed it for a second time. During a part of each complete revolution of the cam shaft 38 the latter turns the carrier 3 the angular distance separating two adjacent pockets, 1. e. one-sixth of a rotation in the present instance; this is effected by pro viding an intermittent gearing between the cam shaft 38 and a short parallel shaft 44 driving the ‘ carrier spindle 31 through the gears 45; prefer ably this gearing comprises locked intermittent gears 46 and 41 which will be understood from Figs. 5 and 6; cooperating toothed portions on these gears serve to turn the carrier 3 during a portion of each revolution of shaft 38 while co operating curved blank portions thereon lock the carrier 3 during the remainder of each revolu tion with one pocket at the crimping station. Also, a cam 53 on the cam shaft 38 serves to reciprocate the crimper to bring the crimper to the roll while the carrier is at rest; for this pur pose the crimper frame links 28 are connected to a cross head 54 sliding in the machine frame (Figs. 1 and 5) and provided with a follower roller 56 to engage the cam; since the shaft 38 and cam 53 are set to one side a lever 55 hinged at one end to the frame is interposed between the ‘cross head 2,110,685 54 and the follower roller 56 (Figs. 1, 5 and 6). Preferably the crimper. head I is pressed to the tube or wrapping yieldingly rather than posi tively; preferably therefore the roller 56 simply supports the cross head and associated mechanism against'the cam, so that as the high point of the cam passes from‘ beneath the roller the cross head and crimper can fall; gravity alone may serve to depress the crimper, but if necessary the weight 10 of the parts can be supplemented by a spring 57 fastened at one end to the frame and at its other end connected to the cross head, say through the agency of an interposed lever as illustrated. As will be observed from Fig. 6, the 15 intermittent gear 46 and the cam 53 are so asso ciated that a new roll is brought to the crimping station while the crimper I is held elevated, but during the period wherein the carrier is locked at rest with a coin roll at the crimping station, the 20 ‘crimper I is reciprocated down against the end of the roll to form‘ the crimp and then is lifted again away from the roll. The clamp 33 which serves to hold the roll against rotation during the action of the crimper I, may be a simple slid 25 ing member as illustrated, indented to somewhat 3 adapt the machine initially for handling a munber of sizes of coins by providing the crimper frame 2| with a corresponding number of crimper heads I, la, lb, etc., and by making the crimper frame rotatable at the will of the operator. The crimper heads can be mounted around the frame 2| as illustrated, each being supported and driven like the crimper head illustrated in section in Fig. l. The crimper frame 2! may be provided with indexing means whereby it can be locked 10 with any one of the crimpers in position above the crimping station; for example, it may have a plurality of notches 68, one above each crimper, into which the latch 69 can enter. Thus, by simply lifting the latch 69 the crimper frame can 15 be turned to bring another crimper Ia, lb or lo, etc. to operating position. » It will be understood of course that my inven tion is not limited to the details of construction and operation illustrated in the accompanying '20 drawings and described above, except as appears hereinafter in the claims. What is claimed is: 1. In crimping mechanism of the kind de scribed, the combination of a crimper head, a 25 carrier for the articles, said carrier having an span the roll and provided with teeth at its end to engage the outside of the roll; if necessary, upwardly and downwardly open pocket adapted teeth 59 may be provided at the wall of the pockets to receive the articles by movement thereof in 4 of the carrier 3 to engage the opposite sides of a path entirely above the bottom of the pocket the rolls from. the clamp 33 (Fig. 4). As shown and said carrier having a loading station whereat in Fig. 1, the clamp 33 can be positioned to engage said pocket is exposed for hand loading, a ?xed 30 the rolls through the peripheral holes 32 in the plate to close the bottom of the pocket and pro carrier and thus compress the rolls against oppos vide a support for an article in the pocket at ing walls of the carrier and against the teeth 53. Preferably the clamp 33 is actuated in a yielding said loading station and opposite said crimper head, the bottom of the pocket being open at manner; i. e. is moved to its clamping position by another point to permit the discharge of a means of a spring 60 so that the clamp without crimped article from the pocket, said carrier also change is adapted to operate the rolls of various diameters; one end of this spring being ?xed to being movable to carry the articles to be crimped along said plate from said loading station to po~ 40 the frame, the other end can engage for example, sition for crimping, and associated mechanism to 40 a pin on the'lever Bl by which the clamp 33 is reciprocated. A face cam 62 on the cam shaft 38 is arranged to engage with the follower roll 63 on the lever 6| to withdraw the clamp 33 from each roll, say just after the crimper l is raised from a roll, and to allow the clamp spring 6|] to press the clamp 33 against the next roll just before the crimper comes down into engagement with the roll and while the crimper is acting. 50 The operation of the machine illustrated will be understood from the foregoing. In brief, the operator stands each tube of coins on its already crimped end in a pocket 4 of the carrier 3, rest ing on the frame plate 34. He then depresses .55 his pedal, and consequently the carrier 3 is stepped around su?iciently to bring a new pocket, and presumably a coinroll, to the crimping sta 45 tion and then the carrier comes to rest. The clamp 33 then operates to press against the roll 60 now at the crimping station, and the crimper I descends, rotating, makes the crimp and returns to its position in Fig. 1. As the result of the same movement of the carrier a roll previously ?nished was brought above the opening 35 in 65 the frame plate 34 and fell therethrough into the chute 36. The operator may depress the foot pedal as rapidly as he can feed rolls to the carrier; the operating rate depends therefore only on the handiness of the operator. After rolls of one size of coin have been han 70 dled, rolls of another size can be handled by sub stituting another carrier plate 3 provided with pockets 4 suited to the .new size of coin, and by substituting a proper size of crimper l for the 75 crimper previously used. Preferably, however, I operate the crimper head and the carrier. 2.
