MACHINE FOR TURNING BUTTONS.

SPECIFICATION forming part of Letters Patent No. 497,349, dated May 16, 189,3. Application tiled July 25, 1892. Serial No. 441,132. (No model),

.To all whom t may concern,.-

Be it known that I, DILMAN BRUBACHER SHANTZ, manufacturer', of the town of Berlin, in the county of Waterloo,in the Province of ticles and the object of the invention is, first,

to provide mechanism whereby the tools may be made to operate upon the blank so as to quickly turn both the back and front ofthebutton into shape and then much more gradually operate upon the partially finished button so as to turn it out perfectly finished; secondly, to provide a means whereby each jaw on the intermittently revolving disk which holds the blanks may be forced open so as to drop the remnant of the blank after the turn-` Y ing of the button and held open so as to give time for the placing' and grippingof the blank between the jaws during the period that the cutters are operating upon the preceding blank; thirdly, to provide mechanism whereby the jaws will not only hold `the blank se'- curely during the period that it is moving into position but further will retain the jaws upon blanks so'as to withstand the action of the cutter and prevent it from throwing the blank out of position in the jaws during the period that the button is being turned; fourthly,to provide an adj ustableshield whereby the button when completed may be prevented from being thrown against the opposite cutter and having the front surface of the button defaced; iifthly, to provide a simple meansforrotatingthediskcontaining thejaws as stated at regular intervals so as to bring the jaws opposite the cutters, and sixthly, to provide a means whereby the disk may be held perfectly rigid during the period that the cutters are operating to turn the button, and it consists essentially, first, of connecting the ends of the cutter spindles to levers which are pivoted at the top of the frame of the machine and are reciprocally adjustable during the revolution of the spindles by cams of peculiar construction which operate within a cage connected to the lower end of the levers; secondly, of providing a pin on the inner end of the spring jaws, which pin extends through the disk upon which' the jaws are pivoted and comes against and is designed to travel upwardly against the inner face of a spring arm so as to hold the jaws open until released by the operator; thirdly, of forming the adjustable pivoted half of the jaw in two parts and providing a spring to normally hold the two parts of the one half against the other half and further in providing a split plunger each half of which is conneeted to a pivoted lever which is held by springs at its bottom end so that each half of the split plunger will maintain an equal pressure against its-corresponding part of the adjustable half of the jaw and thereby insurea blank of unequal thickness being held securely between the jaws and also in providing a plunger which is supported in bearings and is operated by a cam secured on one end of the main arbors so as to come against the lower arms of the levers and'tilt them on their pivot so as to remove the split plungers from their contact with the two parts of the adjustable half of the jawy when the button is finished and thereby allow of the disk rotating; fourthly, of a shield pivoted on the end of van arm which is connected by'a rod to the top of the cage within which one set of the main cams work; ifthly, of providing a ratchet pinion on the end of the main disk spindle which ratchet has a corresponding number of teeth to the open jaws within which the blank is held and is o erated by a pawl from a grooved cam on one t' the main arbors; and,` sixthly, of cutting notches in the main disk corresponding in number to the number of jaws and providing a dog which is brought at certain intervals by a cam into the notch and held there by a spring behind the dogthe whole being arranged and constructed in detail -as hereinafter more particularly eX- plained. l

Figure 1, is a perspective view of my maychine portion of the disk being broken away.

Fig. 2, is 'a perspective View from the opposite side of the machine. Fig. 3, is a skeleton view showing the means of driving the disk wheel, operating the split plunger, and the dog for holding the disk wheel stationary. Figs. 4 and 5, are details of blanks. y

In the drawings like letters and numerals of reference indicate corresponding parts in l the cage is held perfectly steady. When the each igure.

A, is the main driving shaft which is supported in bearings in the frame of the machine and has worms, B, B', secured to it, which mesh with wornrgears, C, C', secured on the ends of the arbors D, D', which extend across the machine at right angles to the shaft A, and are supported in bearingsin the frame, E.

F, is one cutter spindle and, G, the other. The cutter spindles, F, and, G, are provided with pulleys, F', and, G', and cutters, f, and, g, at the ends of the spindles, F, and, G, respectively. The spindles, F, and, G, derive a rotary motion from belts which pass around the pulleys, F', and, G', respectively and are journaled in the frame of the machine as shown.

l-I, and, H', are levers pivoted on the heads of the screws, h, and 7L', which are ad j ustably secured in the standards, c, and, e' by jamnuts, h".

I, and, I', are spring arms secured to the top of the lever, H, and extending partially across the machine in the form shown. The free ends of the arms, I, and, l', are connected by the spiral springs, t', and, t', to the cross rod, J, which extends between the standards, e, and, e'.

j, and, j', are brackets secured at the center portion of the levers, II, and, Il', and having the forked bent end as shown. The bent end of the brackets, j, and, j', extend into annular grooves, f', and, g', made in the end of the cutter spindles, F, and, G, respectively.

K, is the cam secured on the front end of the arbor, D. The arbor, D, revolves in the direction indicated by arrow and carries with it the cam, K.

L, is a cage having a screw spindle, Z, extending from its outer end through the trunnien, M, pivoted in the lower end of the lever, 11.

N, and, O, are jam nuts situated one at each side of the trunnion, M, and designed to adjust the screw spindle in relation to the lever, H. The trunnion, M, permits of the free horizontal movement of the cage, L. The inner end of the cage, L, has a supporting link, P, which is connected at tlie top by the screw pin, 1), and at the bottom by the pivot pin, q, which permit of the forward and backward movement of the cage, L.

Q, is a supplemental cam arm pivoted at, r, on theframe of the machine and extending up into the cage, L. The cam,Q, is provided with a portion, R, concentric to the center revolution of the arbor, D. f

lo, is a series of rollers situated on the cani, K. The curved line passing through the center of these rollers is concentric to the center revolution of the arbor, D. The rollers, k, are designed to come in contact with the concentric portion, R, of the cam arm, Q. As the rollers pass the concentric portion, R, andthe roller 2, passes over the concentric portion, 3,

last roller, 7.5, has passed the concentric portion, R, it rises upon and follows the curved portion, R'. The portion, 4, of the cam, K, at the same time presses against the roller 2, and causes the cage to move in the opposite direction to that indicated by arrow and throws the cutter spindle, F, in the direction indicated by arrow. The curved portion, R', is so arranged in relation to the cam, 4, that the distance between the last roller, o,on the cam, K, and the outside edge of the portion of the cam, 4, pressing upon the roller, 2, exc-- actly fills up the space between the roller, 2, and the curved portion,R', during the period that the roller, t, is ascending the curved portion, R'. When the last roller, lt, has left the curved portion, R', the eccentric portion from, 4, to, 5, which is an eccentric of very slightly increasing radii operates upon the roller, 2, so as to very gradually force the cage and consequently the cutter spindle forward thereby very slowly turning off the face of the button so as to leave a perfect iinish on it. A concentric collar, 3, during this period is passing the minor concentric portion, R", so as to hold the case rigid in relation to the movement of the lever, H. When the point, 5, has been passed the spring, i, at the top of the arm, I, operates so as to bring the roller, 2, on the cage in the direction indicated by arrow along the portion from, 5, to, 6, thereby causing the cutter to recede from the face of the button after it has finished it. During the period that the roller, 2, is passing along the portion from, 5, to, G, the first roller is approaching the point beneath the concentric portion, R, and rises and passes along the concentric portion, R, thus holding the cage perfectly steady. As the roller, 2, passes along the portion from, 5, to, 6, it will of course be understood that the cutter spindle is caused to move in the opposite direction to that indicated by arrow and thereby withdraw the cutter from the face of the button.

K', is a cam secured on the outer end of the arbor, D'. rlhe arbor, D', and cam, K', move in the direction indicated by arrow. The cam, K', is made upon larger radii than the cam, K, so that the cutter, g, is brought up to the blank more quickly than the cutterf, and cuts more rapidly upon the back of the blank. Consequently the cutter, g, will start to operate upon the blank before the cutter, f.

Q', is a cam arm pivoted at, o", and extending up into the cage, L', as shown.

7e', are rollers made on the face of the cam, K'.

Z', is a screw spindle attached to or for1ning part ofthe cage, L', and extending through the trunnion, M', in the end of the lever, Il'. N', and, O', are jam nuts situated on the screw spindle one on each side of the trunnion, M'. The cage, L', is supported at its inner end by the link, P', which is pivoted IIS at the top on the screw pin, p and connected at the bottom to the cage, L', bythe pivot pin,

q. The portion, '7, of the cam, K', starts to operate or press upon the roller, 8, at the same time that the portion, 4, of the cam, K, starts to operate or press upon the roller, 2, but as the cam, K', is of larger radii than the cam, K, it moves the cutter, g, forward more quickly than the cutter, f. As the cam continues to revolve the eccentric portion, 7, of very rapidly increasing radii, causes the cutter, g, to move forward much more quickly than the cutter, f. During the first portion of the period that the portion, 7, of the cam, K', is acting upon the roller so as to throw the cage, L', in the direction indicated by arrow the last roller k', passes up the curved upper portion, R' of the cam arm, Q', thus holding the cage rigid in its relation to the movement of the lever, I-I'. When the last roller, la', has passed the top point of the cam arm, Q', the portion, R4,.

comes in contact with the concentric hub of the cam thereby also continuing to hold the cage rigid in relation to the lever, H', until the leading roller, la', reaches the position shown in the drawings when it mounts upon the then concentric portion, R5, which still continues to hold the cage rigid as to its relation to the lever, H'. This rigidity is maintained until the last roller passesthe concentric portion, R5, and curved upper portions, R4, and, R3, and in fact throughout the whole movement of the cam. l should mention that when the point, 9, of the cam, K, passes the roller, S, the cage is thrown in the opposite direction to that indicated by arrow by the spiral spring, z', a steady movement being maintained by the cam arm, Q', as hereinbefore described.

It will be seen from what has been before described that the cams, Q, and, Q', are designed to keep the cages, L, and, L', rigid in relation to the movement of their levers, H, and, H', which control the backward and forward movement of the cutters. They might, however, be dispensed with but I find in practice that it is preferable to provide these cam arms as the movement of the cutters both as they move forward to the blank and leave the finished button is very steady and consequently neither the face nor the back of the buttonV will be defaced.

It will be seen on reference to the length of the operative cam, K', in relation to the length of the operative part of the cam, K, that the cutter, g, will continue to move forward for a considerable longer period than the cutter, f, the cam, K, being so arranged that the cutter, f, will recede after having finished the face of the button while the cutter, g, is still moving forward to finish the back and sever the button from the blank. These forward and backward movements vof the cutters,f, and, g, are regulated to take place when the disk is brought around so as to present the open jaws opposite the cutters.

draw it from the notch, 15.

The mechanism by which the disk is caused to revolve intermittently so as to bring the open jaws opposite the cutters andhold the disk steady I shall now describe. S, is the disk which is secured on the en'd of the counterY shaft, s, journaled on the frame of the machine. In the disk shown in the drawings there are four notches, t. s', is a ratchetwheel secured on thev opposite side of the counter shaft, s, and, s,`is a pawl pivoted on the arm, T, which is loosely journaled on the end vof the count-er shafts. T', is a link connecting the arm, T, to the arm, U, secured on the rocking spindle,u. U', is an armsecured at the opposite end of the rocking spindle, u, and having a pin, u', which extends into a cam groove, u", in the collar, U", secured to the arbor,D. The rocking spindle, u, is journaled in suitable bearings in the interior of the frame of the machine. It will now be understood that every revolution of the worm to turn the disk, S, only duringk the period that thel cage, L, lever, H, andA consequently the cutter, f, is' held stationary and away from the face of the blank. When the cam is operating so as to move the cutter backward and forward the pin, u', at the .end of the arm, U', travels in the straight portion, u". It will consequently be seen that the disk, S, will always be held stationary during the period thatthe cutters are operating upon the blanks so asto turn and finish the button. In order 'to provide a means which will hold the disk, S, perfectly rigid I provide a stop arm, V, which has a tooth, o, formed on the upper end which is designed to fitin the notch, t, in the disk, S. W, is a spiral spring which is located behind'the stop arm, V, and is designed to hold the tooth, v, into the notch, t. In order to provide means whereby the tooth, o, may be removed from the stop arm when the button has been completed and IOO IIO

fallen out Iprovide the following mechanism. f

X, is an y arm secured on the other end of the rocking spindle, w, and having a pin, .90, which fits the cam groove, made in the collar, X' secured on the arbor, D'. When the cutters have completed the button and it has fallen out the pin, ce, reaches the off-set in the cam groove, on', and rocks the stop arm, V, so as to withu", is so arranged thatl it will operate on the pin, u', of the arm, U', so as to bringthe disk around to the next notch when the spring, W,

The cam groove l will force the tooth, n, into the succeeding notch, t. This operation will take place after each button is completed.

I shall now describe the pivoted jaws and the means for holding them open and closed. Y, are stationary portions of the jaws for holding the blank which jaws are secured in circular holes made in the disk, S. y, y', are the two portions of the jaws which are pivoted at the center or hub portion of the disk as shown and are held normally against the sta tionary portion, Y, of the jaws by the spring, z. z', are pins which are located behind the pivoted portions, y, y. Z,is a stationary cam guide provided at the top with a handle, Z. When the disk, S, is caused to revolve as hereinbefore described the pin, z', cornes in contact with the lower portion of the stationary cam guide, Z, and travels along it. When the pin, z', comes in contact with the cam guide it is forced inwardly so as to throw the jaws, fg, y', away from the stationary jaw, Y. The jaws now will travel around open until they reach the upper portion of the cam guide, Z, at which period the disk, S, is caused to stop and is secured in position by the stop arm, V. It will now be seen that the jaws, Y, and, 1 ly', willremain apart during the period that the cutters, f, and, g, are operating upon the preceding blank thus giving the operator plenty of time to place the blank between the jaws, Y, and, y, y. Vthen the operator inserts the blank between the jaws, Y, and, y, y', he pulls down the handle,Z, which as the cam guide is made of spring metal allows of it being withdrawn from behind the pin, z', andthe spring, z, connected to the jaws, thy', force the said jaws inwardly so as to securely grip the blank. Vhen the cutters have turned out their preceding button the stop arm is withdrawn from contact with the notch, t, in the disk, S, which is again caused to revolve bringing with it the next succeeding jaws, Y, andyy, y,with the blank held between them.

When it has been brought around opposite the cutters the tooth of the stop arm is caused as hereinbefore described to drop in the notch, t, and thus hold the disk stationary. Each succeeding blank is inserted, held and comes up into position in the same manner. I may here state that the one half of the jaws are made in two parts, y, y', so that they may with greater facility hold a blank of unequal thickness and in order to provide an abso lutely secure way of holding the jaws, y, y', against the blank of unequal thickness I provide the split plunger, 10, which is made in two parts, 11, and, 12. The split plunger is supported in the socket, 13, and is cut away on each side at, 14, as shown. 15, are two levers which are placed closetogether and are pivoted on the pin, 16, in the bracket, 13', forming part ofthe frame of the machine. The top end of each lever extends one at each side of the split plunger, 10, into the notch, let. The lower ends of the levers, 15, are connected by strong spiral springs, 17, to any suitable portion of the machine as indicated in Fig. 3. plunger supported in suitable bearings in the interior portion of the frame of the machine. 19, is the head of the plunger which isof a diameter greater than from outside to outside of the edges of the two levers, 15. 20, is an annular groove made at the other end of the plunger, 18, and, 2l, is a rocking arm pivoted on the arbor,D2, provided with afriction roller, 22, at its upper end and an extension, 23, which fits into the annular groove, 20. 24, is a cam projection formed on the collar, 25. The projection, 24, forces the rocking arm and consequently the plunger in the direction indicated by arrow upon every revolution of the arbor, D', so that the lower portion of the lever is pressed in the direction indicated by arrow and withdraws the split plunger from contact with the portions, y, y', of the pivoted jaw immediately upon the button being completed. As soon as the jaws are again brought up into position opposite the plungers in the manner hereinbefore described the split plunger, 10, is again thrown against the portions, y, y', so as to hold the blank securely in position during the period that the cutters are operating upon the blank.

In order to provide a means whereby the face of the button may be protected trombeing defaced after it has been finished and ejected through the hole, Y', I provide a shield, 26, made preferably of very thin metal which is secured on the ends ot' the pivot arms, 27. 28, is an extension arm forming part of the pivoted arms, 27, and connected by the rod, 29, to the arm, 30, secured to the 18,"isa` IOC lilik, P. It will now be seen that upon the lower end of the lever being thrown back by the cam and consequently the cutter with-` drawn the shield, 26, will assume the position shown in the drawings before the cutter so that the button will be thrown against it and fall out without any danger of its coming in contact with the cutter. Normally the shield is held up from between the cutter, f, and the disk, S, but upon the face of every button being completed it will be thrown down into the position shown so that when the cutter, g, is finishing the back it will force the button out so that it will strike the shield and fall down without it being defaced.

In order to provide a means whereby the disk may be prevented from vibrating iu the slightest degree while the cutters are operating upon the blank between the jaws I pro- Vide a shoulder, 31, which is secured so that its end will rest against the opposite side of the disk to that on which the split plungers are held against the adjustable jaws.

It will be understood from the description that each button is finished at the back and front practically simultaneously. It will also be understood that on account of. the graduated longitudinal movement of the cutters, f, regulated by the cams, K, the face and back of each button will be perfectly iinished.

It will also be understood that heretofore in machines in which the pressure has been maintained by a spring jaw aloneit has been found that the blank has frequently been partially misplaced and as av consequence the blank spoiled but by my providing the supplemental split plungers, 10, operated as dcscribed I find in practice thatI can maintain such a strong pressureupon the jaws that it is impossible for the blanks to get misplaced.
