RIVETING- SPECIFICATION forming part of' Letters Patent No. 436,447, dated September 16, 1890.

Application filed December 3l, 1888. Serial No. 295,026. (No model.)

.To all whom it may concern,.-

Be it known that I, J ACOB J. UNBEHEND, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Riveting-Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invent-ion Arelates to improvements in rivetingmachines of the particular class which are designed to insert one or more rivets in to articles for the purpose of facilitating their manufacture or firmly securing buttons, buckles, or clasps, dac., to coats, straps, arctics, clothing, and other like articles; and it has for its object the production of a simple, effective, and efficient device into which the rivets are inserted promiscuously and by which they are fed one by one to the plunger or other inserting' mechanism.

To this end it consists, essentially, in a hopper of novel and peculiar construction, into which the rivets are emptied and from which Athey are discharged continuously and automatically by means of the peculiar construction of the hopper, a conveyer for conducting the rivets from the discharge of the hop per to the plunger, and a suitable cut-off interposed in the conveyer between the hopper and the plunger, and also worked automatically and continuously.

It also consists in the detail construction and arrangement of the parts, all as hereinafter more fully described, and pointed out in the claims.

In specifying my invention reference is had to the accompanying drawings, forming a part of this speciication, in which like letters and figures indicate corresponding parts in all the views.

Figure l is a front elevation of the upper part of my rivet machine, illustrating the relative construction and arrangement of the hopper, the eonveyer, the cut-oft', the plunger, and the actuating mechanism, only such parts of the latter mechanism being shown as are necessary to a description of my improvements. Fig. 2 is a side elevation of Fig. l, more fully illustrating the actuating mechanism. Fig. 3 is an elevation of theopposite side of Fig. l to that illustrated in Fig. 2.

Fig. 4 is a longitudinal vertical section of the hopper with the cover removed, illustrating the detail construction and arrangement of said hopper and showing the rivets in natural detached detail ot' the rivet-conveyer and the cut-off. Fig. 9 is an elevation of the detached cut-off. Fig. lO is a transverse section of the conveyer, taken on line 06,1; and Fig. 11 is a longitudinal section of a friction-ratchet conveying motion from the actuating mechanism to the hopper.

A represents the main frame of my machine, supported on which are the actuating mechanism, the hopper J, the conveyor N, the plunger P, and the cut-oif R. I have only illustrated the upper part of the main frame or bracket A, in which slides the rod or connection B, pivoted to one arm C of the bellcrank C, the other arm C2 of which is pivoted at C4 in the head A of the main frame. c the bell-crank C is pivoted by the connec tion D to the sliding block or plunger P,which is guided in the head A and carries the plunger-rod P.

Motion is conveyed to the rod or connection B in any suitable manner by any desirable means, and it will be seen that when the same is forced downward the bell-crank C, by means ofthe connection D, forces the plunger-rod P down upon the rivet, which has been inserted into the feeding tube or pocket T in a manner presently described.

Provided upon the arm C of the bell-crank is a stud C3, riding in a slot E', provided in the lever E, pivoted to the frame A at E3, which lever actuates the hopper by a connection e, pivoted. at its upper extremity., and actuates the cut-oft R by a connection e', secured to its opposite extremity. As seen in Fig. 1, the connection e, pivoted to the upper extremity of the lever E, is hinged to the pivoted lever f, carrying a dog f', engaging a ratchet g, mounted on the bolt or spindle h,

IOO

to which is secured an arm t', engaging t-he agitator or feeder M of the hopper. Thus it will be seen that the plunger-rod I" is forced downward through the feeding tube or pocket T, inserting the rivet into the article interposed between the extremity of the feedingtube and a suitable block or die T', supported beneath said feeding-tube in an arm A2 of the main frame. lVhen, as described, the lever E is rocked to operate the plunger-rod P', at the same time, by means of the connection e, this lever E rocks the lever f, causing the dog f', secured on said lever f, to partly rotate the ratchet g, and also, by means of the connection e', as presently described, it feeds a new rivet into the feeding-tube T after the plunger-rod has been retracted to its normal position.

In order to insert ythe rivets into the desired article,it is necessary that they shall be fed shank foremost into the feeding-tube T, beneath or in the path of the plunger-rod P', and in order that the machine shall be continuous and effective in operation it is also necessary that but one rivet shall be fed ata time, and that there shall be a continuous feeding of the rivets to the feed-tube with every operation of the plunger-rod.

In riveting-machines as previously devise the feeding mechanism has been more or less defective, especially where rivets are used having their shanks bifurcated, and as the rivets are emptied promiscuously into the feeding device there is always a liability of such device becoming clogged and a consequent breaking or undue straining of the actuating mechanism.

My hopper J preferably consists of a circular frame J', having a removable cover K, sufficient to allow of the ready insertion of the rivets into the hopper or of the ready withdrawal of any of the parts thereof for the purpose of cleaning or replacing with new ones. This frame J is preferably mounted upon the head A' of the bracket A, or a support A2, secured thereto, is held atan angle to the head A', and is preferably provided with the guideways j, engaging like ways on the head A', as shown in Figs. l and et. The guideways allow the frame J to be readily placed at the desired position upon the head A', or the support As secured thereto, and when in position the hopper is firmly secured by a screwor bolt j. The frame J'is provided at its base with a bearing for the feedingrivets, and, as best seen in Figs. 4, 5, and 6, a portion of this bearing is cut out, thus forming an arc of an annular ring L, on either side of which is the space or cut-out L', and when desired the bottom L4 of this open space L' is removable from the rest of the frame J '1.

Mounted in the frame J', I provide the agitator or feeder M, actuated by the arm t', secured to the rod or bolt h, rotated by means of the ratchet g. The lower face of the agitator M is provided with notches or cut-outs m of a size sufficient to allow the ready endischarge-way J2 and discharged, shank uppermost, into the conveyer N, which is connected to said discharge J 2.

The conveyer N, as shown in Fig. l0, is provided with a slot n, of suflicient width to receive the shank of the rivet, and a slot n' at the base of the slot n, of sufcient size to receive the head of the rivet, which head is retained in position by the overlapping edges n2 of the slot 'n'. The rivets, as described, are discharged into the conveyer shank uppermost, and, as shown in Fig. l, this conveyerN is turned so as to feed the rivets into the feed-tubes T, shank downward, in the desired position.

From the fact that the rivets are inserted promiscuously into the hopper it is obvious that only a small proportion will be in the desired position to enter the slots m m in the agitator, and that some will be caught by the edges of these slots and will be borne around the hopper without being discharged therefrom, and that in a short time the said slots would become filled with rivets, or the rotation of the agitator would be checked and serious injury would result; but as the frame J and agitator M are placed at an angle all rivets caught by the agitator, but not forced directly into the slots m m' in posi-y tion for discharge therefrom, will drop backward out of said slot by the force of gravity. The rivets will be again engaged by the agitator M, or should any of the rivets be borne upward beyond the way J 2 without being discharged thereinto they will, when they are rotated around the annular arc L, kbe forced on either side thereof into the cut-out L' and will fall to the lowest point of the hopper, where they will be again engaged.

To insure the forcing out of the notches m m' of the agitator M of rivets which are secured therein, but not in the desired manner to be fed into the discharge J2 when they are rotated over t-he arc L, I continue the cut-out L' upward back of the arc L, forming aspace L2. Just before the end of this cut-out L2, I provide a stop L2, Fig.` 6, which engages such rivets as may be carried around thereto and forces them out of the notches into said space, whereupon they fall by gravity to the lower part of the hopper, as shown by rivets 1, 2, and 3 in Fig. et. It will thus be seen that the agitator M is constantly revolved with every movement of the bell-crank C, and that there is a constant feed of the rivets to the conveyer N, provision made for any catching of the same, and the agitator kept free for the IOO IIO

by means of the peculiar construction of the ratchet g. This ratchet g, as shown in Fig.

11, consists of a ring g', the center of which is provided with an annular opening g2 and provided with annular' shoulders g3, formed on the top and bottom face of the ring g' by annular cutouts of larger diameter than the central eut-out or opening g2.

Mounted upon the annular shoulders g3, I provide the disks g4, which are clamped together by means of screws g5, tightly abutting lthe same against these shoulders g3 of the ratchet g. The rod h, upon which is mounted the arm t', actuating the agitator, is irmly secured to these disks g4, and the clampingscrews g5 only contact these disks g4 against the separate shoulders of the ratchet g sufficiently tight to insure constant rotating of these disks with the gear g and a consequent rotation of the agitator M. If a rivet should become caught therein, the gear g, although actuated as usual by the dog f, slips around the disks g4 without rotating these disks and operatinglthe agitator M, thus obviatingany liability of breakage or strain to the parts.

At a point on the conveyer N, interposed between the hopper J and the feed-tube T, I provide the cut-off R, having lugs R' projecting therefrom, and having a space R2, adapted to iit the head and shank of a rivet interposed between these lugs and normally registering with the slots n n of the upper part of the conveyer N.

In the conveyer N, I provide the slot N', through which the cut-off is operated, and I set off the slots n n' in the lower part of the conveyer N, so that when the slot R2 is registered with the slots of the upper part of `the conveyr N the slot in the lower part of said conveyer will be blocked by one of the projections R', and a rivet will feed down into the space R2 of the cut-off. When by the operation of the lever E and the connection e' the cut-off is forced to register its slot R2 with the feeding-slots n n', provided in the lower part of the eonveyer N, the rivets in the slots of the upper part of the conveyer N are blocked by the opposite stud or projection R', and the rivet between the projections R' is registered with the slots in the lower part of the eonveyer, and is thereby guided to the feed-tube T. Thus itwill be seen that when the agitator is continually feeding rivets to the cut-olf these rivets are fed to the feeding-tube T only by the operation of the cut-off, and then at the proper time, one by one, they are allowed to slide down the slots n 'n' in the lower part of the cut-o and drop into the feeding-tube T in the desired position, shank downward, with lthe head retained by suitable means until the plunger is forced downward and the rivet forced out of the feeding-tube T, which is of construction to separate and allow the rivet to be forced therethrough when actuated by the plunger. If from unusually ready entrance of the rivets into the agitator the conveyer should become filled with rivets above the cut-o, no

serious result will follow, as the peculiar clonstruction of the hopper will allow the rivets to be disengaged from the agitator, and by the operation of the cut-off the rivets will be discharged from said conveyer, thus gradually leaving room for others to feed out from the discharge J 2. The face R3 of the cut-off, from which extend the projections R', is preferably wider than said projections, which are only sufficiently wide to equal the diameter of the rivets, and I provide a simple guidewayfor said eut-off by continuing the upper and lower divisions of the conveyer, soas to abut against these projections R2 and overlap upon said face R3, thus securely retaining the cut-off from disengagement. provided upon the cut-off to limit its movement, and while any suitable connection would suffice to convey motion from the lever E to the cut-off R, I preferably use a spring, which,

Suitable stops R4 are if a rivet should become caught in the cut-off,

wouldgive sufficiently to allow the lever to work without operating the cut-off, thus preventing undue straining of the parts.

In the operation of the cut-olf I provide a screw r, against which the spring e abuts, and

which can be readily adjusted to the desired space to just operate theeut-off without unduly wearing the stops R4.

The operation of my machine will be readily perceived from the foregoing, and it will be seen that the rivets are emptied promiscuously into the hopper, continuouslyy fed therefrom to the cut-off, and thus fed one by one to the feeding-tube T, shank downward,

in the path of the plunger or inserting mech- 1 anism, which is operated immediately upon the insertion of the rivet.

Considerablerchange may be made in the detail construction and arrangement of my IIS machine without departing from the spirit of my invention, and it will be seen that as the hopper may be made of hard metal there will be but little wear, and that from the peculiar construction of the parts of the hopper and cut-off there is no liability of any straining of the Iparts from catching of the rivets, thus producing a simple and very efficient machine for the purpose desired without any liability of undue wear or strain.

IIaving thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is` Y l. In a rivet-setting machine, the combination of a hopper-frame, a bearing-face in said frame disposed at an angle to a perpendicu-` lar, a feeder rotating within said frame above the bearing-face, cut-outs m and m" in the lower face of said feeder for receiving the rivets, a discharge-opening in the hopperframe through which the rivets feed when said cut-outs are registered therewith, and a cut-out L in the upper part of said bearingfaceand extendingbelow the said bearing-face, whereby the rivets fall from said feeder when not registered with said discharge-opening, substantially as specified.
