Similar letters of reference indicate like parts.

Our invention consists in the construction and arrangement ot' certainl mechanical devices for riveting buttons to cloth or other material, whereby the cloth is pierced to receive the body of the rivet, and the various movements and opera-tions necessary'to feed the rivet and the button and insert the rivet in the cloth and through the'center of the button and clinch them together are performed automatically. l

l The bed-plate A of our machine, which supports the various parts thereof, is to be xed to a bracket or in a frame, so as not to obstruct the movement of those parts. A supporting'- standard, B, rising from the plate A,1sustains the various devices which are located above it in the several positions seen in Figs. land 2. rllhe arm of the cli'nching-hammer G is 4fixed vby a collar and set-screw upon a short shaft, which rotates in bearings in the highest part ofthe standard l, a shorter arm, .02, onl the samel shaft extends in an opposite direction, its end being bent up slighty, -as seen in the detailed view given thereof in Fig. 12. A spring, D, bolted to the back of the standard, .presses continually downward upon the arm of the hammer. A shaft, F, which has its bearings on the standard in front of the hammer-shaft, carries a cam-plate, E, on one of its rvends, Whose cams, three in number in this instance, are set at equal distance .apart on'its periphery. A pin, e2, is set on' the outer surface ot each of the three cams, Which strikes against the short arm d of a jointed lever, which is jointed loosely to the projecting armof a cross-bar, a., which connects the sliding rods X and A. Therod X slides in *a bearing made t'orit in the projection A3 below the bed, and it should have a longitudinal movement sufiicient to' bring' it against the shorter end of a lever, H, Whose longer end strikes against a sliding` bar, A4, which slides-in Ways ymade for it in the upper part of the solid block U on a line which coincides with that in which the sliding-bar A moves, andwhich passes directly under the needle. The barr A4l is brought out and held against-the lever H after each inward movement by means of an elliptical spring, G', which is secured at its center to thel head ot' the bar by a set-screw, and at one of its 'ends to the face ot' the block U', so that its tension shall bein an outwarddireetion. The inner end of ihe'bar Atis flattened and carved out,

as seen in Fig. 4, to the shape of halfa circle, of a size to tit the body of the rivetto be used. The inner end of the sliding bar'A is formed in a similar manner, and both these bars vare-intended to slide toward eachother at the same time, meeting each other directly beneath the needle, at which time they will grasp the body ot' the rivet between their curved ends, as hereinafter explained.

A rectangular opening, A, is made in the bed-plate A, which receives and iscovered by a pla-tef'm, shown `bottom-'side 'uplin Fig. 9. The object of this openin g is to get access to the channel to setthe rivet in case it gets upset and to get at .the Working parts in that Vchine below the plate m.

portion of the machine, and to see that the rack, when a rack is used, starts right, the part of said plate which ts within said opening being deeper or of greater thickness than the outer ends, which are made thin, so as to lay upon the surface of the bed-plate, as seen in Fig. 4. The solid or thick part of the plate m is planed off, so as to be only about `one-half its original thickness between the shaded line 6 and its side 7 ,Fig 9. Two transverse slots,

q', cut across the thickest portion of the plate,

extend to the line 6, and a needle hole, p, iS drilled through the plate midway between the slots q'. A flat spring, n, Fig. 4, is' secured upon the top of the plate m, having at its end a blunt pin, O, which projects downward through a hole drilled through the plate. :This

`pin O must coincide with the holes h h of the rivet-feeding rack 'T'. which traverses the ma- The rack T' is made of the form shown in Figs.3, 4,. and 5, which show it in plan view from above and beneath, and also in Figs. 1 and 2, which .show it in section. It passes beneaththe bed-plate in its movement and` slides upon the, block U',-

which is planed oi' to make room for it. Its teeth.e11gage with the teeth of a pinion, B', fixed on a shaft, B3, Fig. 3, which hangs down .from the bed-plate. The lower side of the pin ion has a ratchetfwheel, C', cut upon it. The position of the pinion on the machine is such that` its teeth will engage with the raekwhich traverses in front of it, while its ratchet C' will be engaged by a spring-pawl, 8, Fig. 5, fixed upon the upper side of the sliding bar A', whose path is beneath and at right angles with the rack. This pawl is shown in dotted outline in Fig. 5.

The rack'is in practice laid upon a separate table, attached or brought up to the machine at the level of the rack, so as to confine the rivets in their receptacles h, while the rack moves atrossthe machine.

The rivets are supplied to the rack after each traverse through the machine by removing the rack from'the machine, laying it over upon its face, and insertinga rivet ,in each hole h, which holes are countersunk, as shown in the drawings, to receive the `heads-of the rivets, so that theyshall'lie flush fwith the lower face ofthe rack. Allight plate or strip of any suitable material is next laid and held upon the rack, so as to cover the heads ofthe rivets, and the rack is thenl turned over upon ihe table, from which it is to be fed into the machine. The ends of the rack may be dovetailed, so as to tit with the ends of other racks, in order that as one is nearly fed through the machine another may be joined to its end, and thusa continual supply of rivets be provided.

'An endless belt or chain can be substituted for the racks, which substitution can easily be made by any well-skilled :mechanic without further description. When the cross-head a ispushed inward, the pawl 8 of the bar A' engages with the ratchet-wheel C', thereby turning the pinion B', which causes the rack to adany'backward motion. advanced so that one of its holes It is brought vance across the machine a distance equal to the distance between its holes h, the ratchet, pinion, and'rack being made and adjusted so as to produce that result.

A spring-detent, D', secured to the adjacent side of the block U', holds the ratchet against When the rack-has over the channel q, which is cut in the block U', and extended through A2 to make a path ,forthe sliding` bar A', the rivet contained in that hole. h is free to fall into the channel, and it is assisted in so doing by the tpressure of the pin o, which'at the same instant presses upon the point of the rivet through the upper side of the hole in the rack, the object being to prevent the rivet from sticking fast and remaining in the rack at thetime it should fall into the channel g. The head, beingihe heaviest part of the rivet, will be found resting on the .bottom of the channel and its shank will project upward, so as to lie di.- rectly in the path of the curved bar A', which is so adjusted as to come in contact with and embrace one side of the rivet justabove its head as the rivet thenlies. The continuation of the advance of the bar A' will push the rivet along the channel until it' comes directly beneath the needle U, at which time the other side of the shank of the rivet will be met and embraced by the curved end of the sliding bar A4. Y

Thebutt'on-hopper Q is located infront of the punch M, being secured to that part of the standard which furnishes a socket for the needle and the punch. The hopper is open at top, and it has a slot (not shown) down its front to enable the operator to note the order in which the buttons lie.' The hopper opens at bottom into a horizontal channel, V, in which a slide, W, is moved backward and forward by a pin projecting upward from the end of a-bent arm, W27, attached `to a sliding rod,X. A spiral spring, W', is secured on this rod between a collar on its end andone of thc bosses which carry it, and the rod is thereby held so that the slide W will be drawn forwardin its channel, where it will remain in front of and on a level 'with the lowest button in the hopper until it is drawn inward by means of the rod X, as hereinafter described.

The bottom of the channel is slotted longitudinally to allow the holding-pin of the bent arm Wvz to travel with the slide. This slot is continued across the bottom of the hopper and along an. extension ofthe channel behind the hopper, and along the bottom to a `point beyond the center of a receiving-chamber, L', which is formed in the bottom ot the punch' stock K, and which in one position of the stock forms a continuation of the channel V. The position of the slide W in the channel V is adjustable by means of two jam-nuts, which secure its. arm in rod X, so as to enable the same -slideto operate difterent-sized buttons. The hopper Q is made to receive different-sized buttons by sliding a hopper case ot' smallerdiameter within the outer case of the hopper Q, thereby enabling us to use various-sized buttons with the same hopper arrangement.

The rod X is drawn backward bythe nieveinent ofthe lever H, Fig. 1, through the agency ot' the slidingdog1(l,which slides up and down in slot, 13, cut in the arm ofthat lever below its fulcrurn. When the lower limb of the lever His moved backward, its dog 10 comes against the shoulder 11 ot the rod X, thereby drawing the rod X and its slide W backward, the adjustments being so made as that the inner end of the slide shall carry the lowest button in the hopper into the extension of the channel V behind the hopper, and beyond it into a chamber, L, formed in the bottom ofthe punch-stock,the contour of which is to be such as that the perforated button, which is to re ceive the rivet, and is made concave on its face side, immediately` around the perforation, the corresponding lower side being convex, and the rim or edge of the button being flat, as shown in Figs. l0 and l1, will lie in position to releive the body of the rivetfrom below. So soon as the button is placed in the chamber L', the tube or casing J4, which incloses the punch M, is forced down by means of the curved end 2S ot' thc lever H, which bears down upon handle lli, projecting from the collar N ot' the casing J', until it rests lightly upon button, its face being convex in form, so as to tit with the concavity ofthe button around its rivet-hole, so as to center the button and insure its being and remaining in position to receive the rivet. The easing J' moves within the punch-stock X. When the button is in position in the chamber L', and the lower end, lil', of the casing J' has been brought down upon it, a continuation ot' the pressure upon the handle 16 will cause the punch stock K to descend until it meets the rivet-carriagei t below, or, rather, the cloth upon it, which at that time should be in position beneath the chamber L', with a rivet projecting through it, as will be hereinafter explained. The button in that case will pass over or receive the body (f the rivet within the rivet-hole, when the descent of the hammer C upon the punch M will clinch the rivet in the concavity of the button by a single blow. The cloth,being next moved toward the front, draws the button out ot the open side ot' the chamber L', when the punch-stock may be released, the spiral spring L about it serving to raise it again, so as the chamber L will coincide with the channel V. The tube J will also be raised by means ofthe spiral spring K' about it so soon as its handle 16 is released. The punch is also carried upward, being supported within the tube J' by means of its shouder, as seen in Fig. 8, so that it shall not `descend below a certain limit to be iixed by the maker. The punch is shown in Fig. 8 as projecting below the chamber L', being forced down by the weight of the hammer. When the hammer does not rest upon it, it, as well as the tube J', will be raised by the spring K' above the chamber L', so as to clear it for the entrance of a button from the hopper. The tube J and punclrstock are to be guided by key-seats, or by any equivalent devices, so as to prevent them from rotating.

The needle U, fr perforating the. cloth, 1s located behind the punch, and is secured in a needle steek or holder, R, which slides ver tically within a tube, l?, which latter slides vertically in a socket made for it in the standard. The lower part of the tube P has a smalllr tube, T, secured in its end, which tube T incloses the needle, and is slotted throughout its Whole length., as seen in Fig. 7. When the needle and the tube T are in their normal position, the lower end ol' the tube rests upon a Shoulder formed on the shank of the need'e, its shank being ot' smaller diameter above the shoulder than it is at the shoulder, so as that the slitted tube, which is to be made ot' steel or other material which has suitable strength and elasticity", will close around the shank of the needle above the shoulder. The diameter of the tube T externally, when it is in that condition, its slit being closed, will be or is to be the same as the diameter ot' the needle at its shoulder. A cross-head, 19, rigidly attached at the top ot' the needle bar E, extends to and embraces a standard, S, fixed inthe standard B. The cross-head 19 can slide upon the standard, a nut, 20, preventing it from becoming disconnected, and a spi-ral sprin g about the standard pressing up against .the cross-head 19, in order to maintainthe needle in the position shown in the drawings, ready to be forced down through the cloth by the rotation ot' the cam-plate. The cross-head 19 is of the shape shown in Fig.,13, its branch 21 embracing and sliding upon a guidingstandard, Q4, and a recess, 22, being cut in its front to receive a boss on the cross head 18 of the tube P, which'boss in the normal positien of the tube and needlebar rises flush with the cross-head 19. The boss may be dispens d with, and the cam be allowed' to fall from one crosshead upon the other. The cross-headlS is rigidly attached to the tube P, and its arms embrace and slide upon guiding-standards Q4, fixed oneither side of thetube. Spiralsprings about thesev standards, bearing up against the cross head 1S, tend to keep the tube l? in its normal position close up against the crosshead 19. In this example of our invention we have relied upon the force ot' the spiral springs to give limits to the descent ot the needle and of the tube T; but it will be better to limit their movements by stops, which may be located in any suitable position, either within the bearing on which they move or upon the outside, so as to be struck by the heads 18 and 19, which any competent mechanic can easily arrange without further explanation. The needle and the tube are driven downward by means of the cam-plate E, whose cams strike successively upon their cross-heads, irst striking upon the cross-head 19 and driving the,

needle-bar downward, which carries the tube P with it. lhis descent continues until the needle has pierced the cloth lying upon the rivet-carriage 1',when thefurthcr rotation of the cam-plate carries the toe of the cam past the head 19 upon the boss of the head 18, wherebythe slitted tube T is forced downward overthe shoulder of the needle U and through the perforations just made by the needle in the cloth and the hole j in the 4rivet-carriage t" d until it reaches the rivet held in the channel 9 between the rounded ends of the sliding-bars A A4, which it seizes between its elastic sides. So soon as the shank of the rivet has been seized by the tube T the bars A A4 are released and allowed to spring back ready for another advance. The edge of the boss next to the cam plate is inclined or rounded off, so as to aid the camto pass over it readily as it continues its rotary movement. So soon as it has passed the boss the springs on the standards Q4 will elevate the tube T, which returns through the rivetcarriage it and through the cloth until the head of the rivet strikes against the edge 4of the holej,

and is thereby detached from the mouth of the tube T, which continues its ascent until it again closes around the needle-shank above its shoulder. The needle in its descent goes through the hole j in therivct carriage@ z', the

plates i of which are gradually forced apart by the entrance of the needle, which is of tapering form from its shoulder to its point, until its shoulder has passed a little way below the hole, thereby also making a passage for the tube T, which at that instant will be forced by the cam down over the shoulder of the needle, its expanding sides separating the jaws of the rivet-carriage t" z' still farther apart. So soon as the cam slips od' the head 19 onto the boss the needle is free to be drawn up by the spiral' spring on the standard S. When the tube T rises, after the cam has passed ol' its head 18, and brings the rivet up between the jaws i vl, thesejaws spring shut, and hold the body of the rivet projecting through the hole j and through the cloth. So soon as the tube is withdrawn therefrom these jaws are moved from beneath the needle td a position beneath the punchstock, bringing with them the cloth, whichhas the body of the rivet projecting through it, and which is ready now for the descent of the button and the operation of the punch.

The jaws of the rivet-carriage are flat pieces of metal, a hole,j, being made in them (half in each jaw) at the line of their meeting and directly in the path of the needle when the jaws are in a state of rest. at its outer edge to vertical pieces of steel or steel springs F F, which pass down through slots q q in the block U, which slots reach from a line running across the path of the needle to a line running across the path ofthe punch. The springs F are secured beneath the block E toa solid piece of metal, F2, which is perforated to receive a guiding-pin, Uf, reachin g down from the block Ef, so that the rivet-carriage may have vertical play. Y

Euch is connected The springs as they pass down to their block F2 are let into mortises cut in the edges or sides of the sliding block Ef, so that the rivetcarriage will be carried along with it in its movement- This block slides in ways made for it in the bottom of the block U', which in this example are dovetailed, (not shown in the figures.) but which can be made in any proper manner. The block E is moved to and fro by means of a sliding rod, Z, which slides in bearin gs f f on the lower side of the bed-plate, its movements being adjusted as to their extent by collars screwed upon a thread cut on the rod, whichcome in contact with the bearingsff. These adjustments are required to bring the carriage in its movements beneath the center of the needle and button.

A spiral spring, conned on the outer end of the rod by means of a collar, W", and one of the bearin gs f f, returns the block E to its position in Fig. 3 so soon as it is released from the force which drove it forward. I The collar Wftakes the shape ot' an elbow, (see Fig. 3,) which extends across the slot `2 in the bedplate, in order to be in the way of the lever Y, which is pivoted to the standard B above and reaches down through the slot 2. When the handle of this lever is moved outward, the rod Z and block E will be driven toward the front of themachine, carrying the rivet-carriage and cloth and rivet to the desired position beneath the punch. The top of the bedplate at this point'is made with a dat or concave bed of 'a size to fit the head of the rivet, and on each side of this dat or concave bed this part of the bed-plate is rounded off or inclined, as seen at s in Figs. 4 and 5 and in Fig. 14, so as to permit the projections 27 in the bottom of the punch-stock to drive the rivetcarriage downward, and thereby open its jaws wide enough to release the rivet and allow it to slip from between the jaws.

The jaws i i, on their under sides, are made of the shape seen in Fig. 14, rounded or inclined, so as that a gentle blow or pressure will force them to slide over the curved sides s, and the jaws to be thereby forced apart, `as above stated. A

To the opposite end of the shaft F from that on which the cam is secured, is keyed a ratchet, G, whose teeth, three in number in i this example of our invention, answer to the number of the cams on the cam-plate, and are situated in or-about the radial planes extending from the center of the shaft to the several cams. A lever, H, is hung loosely upon the same shaft outside of the ratchet. This lever extends above the line of the shaft, s'o as to be ,formed into a. handle above, or so as to meet a connecting-rod or other device for oprating it, and below the shaft it reaches nearly down to the bed-plate, having a short arm, 26,. which extends laterally outward. across the slot 3 in the bed plate in order "to receive a connecting-rod from below to cause it to vibrate, as hereinafter explained, and also inward toward the standard B, so as to strike the arm 14. The connecting-rodl (not shown) is secured thereon by a nut, 24. A frictionroller, 25, is set on the arm 26 inside of the lever, which, when the lever has got to the by driving the rod Z and rivet-carriage block E' forward, as before explained.

The lever H has a pin, 10, sliding in a slot, 13, in a position thereon that will in the beginning of its vibration to the left strike against the vertical side 11 of the sliding-rod X, carrying it along with it, and thereby feeding the button. Whenthe leverH has vibrated to such a distance to the left that the pin 10 has reached the top of the straight side 11, the pin will slide over the top of the side 11 and be free to move up and along the slot 13 and release the rod X, which will immediately be drawn to its original position by its spiral spring W'.` On the return movement of the lever H, its pin 10 rides upon the inclined -face 12 of the rod X and upward within its slot 13, to permit it to take the position again in front ofthe vertical slide 11 of the rod, ready to feed another button.

An elbow-lever, I, is pivoted to the standard B in such a position as that its stouter arm will reach and act upon the teeth 15 of the ratchet G. Its longer arm, 14,'extending downward, as seen in Fig. 1,lies'in the path of the friction-roller or pin (not seen) formed by the extension of the arm 26, which, on the backward or return movement of the lever H, strikes the arm 14, and thereby causing the short armor pawl of lever I to draw the ratchet and its shaft F around in the direction of its previous movement. The camplate, being keyed to the shaft F, is also thereby moved to an equal distance. This forward rotation of the cam is necessary, because, as we use the same shaft for working the cam and the lever, and the lever moves through only one-fourth, more or less, of a complete circle in its movement from right to left, the cam, which is driven by means of the spring-pawl I' of the lever acting against the ratchet-teeth 15, only makes one-fourth of a complete revolution. This is sufficient to enable it to perform its work on the needle and its tube T, but not sufficient to bring it in position to act on them when the pawl l' next acts on its shaft. The ofce of the pawl I therefore is to rotate the shaft with its ratchet and cam until they have completed their revolution, when the ratchet will be in position to receive the pawl I' on the next vibra-tion of the lever H, and the cam will be in position to strike the crosslheads 19 and 18, as before explained. The detent J, xed to thestandard B, rests continually upon the periphery of the ratchet-wheel G', its office being to catch under one of the teeth of the ratchet when the lever has completed its movement to the left and is ready to return, so as to hold the ratchet and the cam-shaft and prevent their backward rotation. At every partial rotation of the cam-plate one of its dogs, e2, strikes against the end d' of the lever d, which has its fulerum at e' on the standard B. This lever works through the slot 1 of the bedplate, and drives the rod X and the bar A' simultaneously, as before stated.

The outer end, C2, of the hammer-arm curves upward, as seen in Fig. 12, in order to permit the hook Q' of a reciprocating bar, N', to draw upon. the arm in a direction which shall be constantly vertical.

The hook (shown in part in Fig. 6) is connected to a bar, N', and the latter is connected below to a treadle, (not shown,) and is to be held upright in guides, so as to move in a vertical path in such a position as that its outer inclined face, 29, shall, when the bar is ascending, come against the side of the end C2 of the hammer-arm. The bar and hook are hinged at P', and the spring O' holds the hinge closed, allowing it to yield when the inclined face strikes against the arm O2, so as to catch it again under the hook ready for another movement. This reciprtcating hook after each descent is carried upward immediately by a counter-balance arrangement (not shown) of ordinary construction, so that its jointed hook shall again spring over the hammer-arm.

The operation is as follows: The movement of the lower part of the lever H from its extreme position on the right (which is not shown the drawings) causes the pawl l' to engage the ratchet-wheel G, and thereby rotate the cam, and by means of one of its pins, e2, striking the lever d' d, moving the sliding bar'A' and feed a rivet (when a rack or belt is uscd to feed the rivets) into the channel 9 in the path of the ends qof the sliding bars A' and At. The further vibration of the lever H causes the rod X to draw the slide IV inward and feed a button into the chamber L', about at which time one 'of the cams of cam-plate E has depressed the cross-head 19 and 18, and thereby brought the needle down through the cloth, which must previously be laid in position over the rivet-carriage. The continuation of `the pressure of the cam upon the cross-head 18 forces the slitted tube down into the channel 9, over the rivet, which has been by that time brought forward by the sliding bar A' and has been seized upon its opposite side by the sliding bar A4. When the cam has passed the cross-heads of the needle-bar and the tube, they rise successively to their original positions. The lever H, havin g released the buttonfeeding slide continues its movement until it strikes the lever Y, which moves the rivetcarriage, and this carriage, holding now the rivet brought up by the needle-tube between its jaws, is carried forward beneath the punch-` stock, when the continued rotation of the lever H brings its upper end, 28, down upon the arm 16 of the punch-stock, and thereby carries the stock down upon the rivet-carriage, openv ing its jaws by the pressure of its projections 27, so as to release the rivet, and causing the button to pass over the rivet when the hammer descends upon the punch, and thereby clinches the rivet in the concavity of the button. The cloth is then withdrawn with the button riveted to it. The lever I, on the return ofthe lever H, causes the cam-plate and ratchet to complete one-third of a revolution, the detent J having meanwhile prevented any baclrward motion ofthe shaft F. When the driving-lever I' and its spring bear lightly upon the smooth periphery of the ratchet-wheel, there is little or no tendency in the cam-shaft to be rotated backward, and in that case the detent J can be left oft' the machine.

The hopper-case Q receives cases like Q, which rest within it, beingv inserted from above. When itis necessary to feed buttons of smaller sizes than those that fit the capacity of the outer case, we place a spring, D, upon the hammer-arm, so as to give energy andforce to its blow, and thus avoid the necessity of using a heavier and unwieldy hammer.

The machine can be operated by hand through the handle of the lever H, the hammer being operated by the foot of the workvman through a treadle fast to the connectingrod N' 5 or' it may be driven by power in any ordinary manner by connecting-rods and gearing in the way machines are usually driven.
