Specification of Letters Patent.

Patented Sept. 22, 1908.

Application filed April 8, 1907. Serial No. 367,003.

To all whom it may concern:

Be it known that I, JULms G. IIkl-n'rEX- sri-nx, an citizen of the United States, residing at Chicago, in the county of (look and State of Illinois, have invented new and useful Improvements in Presses for Button-Making and Like Purposes, of which the following is .a specilimition, reference being had to the drawings forming a part thereof.

This invention relates to the class of machines which are commonly in the form of a. press having dies which cooperate by movement toward and from each other in successive processes or steps of a process such as are required in making but-tons composed of a. plurality of elements which are assembled and clenched together in the processes performed by the (lies.

The purpose of the invention is to provide improved means for causing one of the dies which has a yielding member to act as if such member were unyielding when coi'i'ierating with one of two opposed (lies with which it is alternately brought into cooperation, while permitting it to act by the yielding of its yielding member while in cooperation with the other of the two opposed dies.

The invention consists of the features of umstruction illustrated and described, as

indicated in the claims.

In the drawings :Figure 1 is a side elevation of this im )rovcd machine. Fig. 2 is a section at the line 22 on Fi 1, showing i110 upper die which has the yielding member in position for cooperating with the lower die with which it is designed to cooperate without the yielding of said member. Fig. 3 is a view similar to Fig.'2 showing, in line for cceperation with the upper die, the die on the carrier which requires the yielding member of the upper die to yield in properly performing the process. Fig. 4 is a section at the. line 44 on Fig. 3. Fig. 5 is a view similar to Fig. 2 showing the lower carrier Fig. (i is a similar view showing the rotating die fiu'rier at a position at which no die is in line with the upper die. Fig. 7 is a View similar .0 Fi 2 showin the device which is interpose between he upper die members for locking it mounted on the standard instead of on the lower die carrier. F ig. 8 is a detail side elevation, partly sectional, showing the locking device of the form shown Fig. 2',

section being made axially through the lower portion of said device.

The structure shown in the drawings coins prises a standard, A, having mounted in ituppcr part a vertically reciprocating head, B, normally upheld by a spring, C, and thrust downward for cooperation of the dies by a cam lever, D, whose action will be obvious from its form as shown in Fig. The upper die carried in the reciprocating head, B, comprises a fixed member, I], and a lyielding member, E. Mounted upon the )ed is an oscillating carrier, F, having its fulcrum at f for swinging horizontally through an arc whose chord IS the distance between the centersol' the two dies, G and II, carried by said oscillating carrier and by its oscillation brought alternatcl into line with the u )p e'r die. Any suit-ablh stops, as the pins, on the bed encountered by the oscillating carrier, limit its oscillation with in the range above stated, stopping it at the opposite limits with the dies u mnit accurately alined, each in turn, wit 1 the upper die, as above described. On the lixcd member, E, of the upper die, there is a flange, E", which is conveniently formed by a nut which serves as a means of securing the die to the reciprocatinghead, B, (this double use of the nut being, however, merely incidental) such flange being in position overhanging thc yielding member, E, of the die and constituting a stop limiting the upward yielding movement 0 said member. The interval between the flange and said yielding member when the latter is at its lower position corresponds to the ran e of yielding movement required. On the oscillating carrier, F, there is mounted a vertically reciprocating element, 'K. This element is conveniently a hollow rock-shalt or sleeve mounted for reciprocation on the stud or bearing shaft, L, which projects up rigidly from the oscillating carrier, a sprin M, being coiled about the stud, L, rcacting lictwecn the latter and the sleeve, or rock-shaft, K, to

ieldingly uphold the latter which is stopped )y a nut, l, on the upper end of the rigid shaft, L. Preferably the sleeve, K, has freedom for a short range of oscillation about the shaft, L, and the spring, M, has its upper end, M, engaged with the sleeve in the engaged at slot, 7:, of the latter, and bein as well as its lower end in the standar struction shown in Figs. 1, 2, 3 and 4.

stopped thereagainst and coiled so as to have locking position in relation te. the upper die at one step of the rotating movementwill-box elastic reaction circularly about its axis, its engagement at the upper end with the sleeve as described causing it to yiel'dingly hold the sleeve at the position shown in Fig. 3. at which it is stopped by the encounter of the short stud, K, on the sleeve against the aln|-tnn.-nt,f, on the carrier. Near the up )erend ol' the sleeve, K, it has a horizon.-

tal v projecting 11". or finger, K, which isat proper position for passing between the flange, IC'", and the yielding member, E, of the up )Cl die when the carrier swings to position tor alining the tower die, G, with said upper die, as seen in Fig. 2. In moving to this position the arm, K, encounters laterally the interior element of the head, B, between the yielding member, E, and the flange, lC, and yields slightly as thedie comes into position to aecommodatev the. diameter of said interior clement, be. it. greater o less; and the purpose. of mounting the element, K,sothat 1t ca nthus vicld about its axis to adapt. the device to cooperating accu- .ratel v and properly with dies of different sizes. in whic the diameter of the center element may be greater or less. The width vertically of the arm, K, is such as to so far occupy the interval between the member, E, and the flange, ll", as to prevent or limit the sliding movement of the member, E, 0;. the interior,element of the d e to whatever extent. such movement is. required to be limited for the proper action of the die. If a slight movement is to be. permitted, the arm, K, will be slightly narrmver vertically than the interval between the member, E, and the flange, E", as shown. It will be seen that when the. die, H, is alined with the up per die, the arm, K, being entirely out of the way of the we cot) )erating dies, the member, E, of the upper die will yield upon its oncounter with the lower die, but when the die, G, is alined with the upper die, such yielding will be prevented to the extent determined by the vertical width of the arm, K, and thatas said upper die descends to cooperate with the lower die, G, the sleeve, K, will be carried down with it, sliding on the said shal't, L, and being restored by the spring, M, as the die rises.

It will be obvious that the expedient hown for locking the upper die may be employed with a lower die-carrier adapted to rotate as well as with one adapted to oscillate as in the figures above described. Such rotating die-carrier is shown in conjunction with the locking device in Figs. 5 and 6, the die-carrier, F, having two pairs of dies, G- and II, the carrier having adjacent to each of the dies, G, the locking device, K, with all its accessory parts of identically the con- It will be seen that as the carrier is rotated, the locking arm, K, having been carried into carried out of such position, yielding freely for rotation about its axial support, ll, 1.. order to pass away from the upper die and out. of locking relation thereto. A spring (atcn, engages a notcl|,j, on the rot: 1tmg carrier at each position at which the ciTfifi'T halted forregistration of one of its dies with the upper die, four ot such notelms-J", being therefore provided when the carrier has four dies as shown.

Instead of mounting the locking devicenpon the rotating or oscillating carrier, it mav be mounted on the standard, as shown in Figs. 7 and 8. Such construction in conncction with an oscillating die is shown in Patent. .\o. 836,916, granted to me November 27, 1906,. In Figs. 7 and S of this application, the salne device. is shown in commction with the rotating carrier. In this form the locking device comprises a hollow rock shaft or sleeve, K mounted for rotation and also [or reciprocation upon the. vertical shaft. or stud, I), which is mounted in the standard, as seen in Fig. 8, vided precisely as in the form shown inthe other tigurcs (Fig. 4) for engaging the slot, R, in the hollow rock shaftor sleeve, K and being stopped endwise against said device for yieldingly resisting its descent and re turning ittoelevated positioi-i. In this form, the lower dies on the rotating carrier with which the locking device is not designed to be engaged have a laterallyoflsetstop linger, I, in position to encounter the arm, K, of the locking device and swing said device. aside to iosition shown in dotted line in Fig. 7 when the dies having this otl'set stop finger come to alinemcnt- 'with the. upper die. To prevent the stop device from being retracted too far about its axis by the spring, .\I, when out of engagement with either die, there is provided a short heel )iece or tail, K corresponding substantia ly to the lower arm, K, of the device shown in Figs. 1, 3 and 4 which stops against the upright shank of th standard, A, as seen in Figs. 7 and 8.
