Specification of Letters Patent.

Patented Aug. 29, 1916.

Application filed November 20, 1914. Serial No. 873,158.

To all @Mom t may concern.'

Be it known that I, JULiUs G. BnnrrnN- STEIN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Presses for Button- Making, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose of this invention is to provide an improved press for making buttons of the class which comprises a plurality of disks of different material suitably assembled and clenched together.

It consists in the elements and features of constiuction shown and described as indicated in the claims.

In the drawings Figure l is a side ele vation of a button press embodying this invention. Fig. 2 is a section at the line 2 2 on Fig. 1. Fig. 3 is a similar View showing the oscillating and reciprocating head at the opposite limit of its range of oscillation from that shown in Figs. l and 2. Fig. t is a vertical section at the line 4 4 on Fig. 3. Fig. 5 is a section at the line,

5 5, on Fig. l.

The press shown in the drawings comprises a fixed base, A, adapted to be mounted rigidly upon a stand or table, said base having an upstanding post, A1, furnished with a vertical fixed shaft or bolt, C, screwed rigidly into the top of the post and affording bearing for the oscillating head, D, which is vertically stopped between the top of the post forming one horizontal shoulder, and the head of the bolt forming an opposed shoulder. In the head, I), there is mounted for reciprocation a plunger, E, which carries the upper die. The plunger is operated by a cam, F, pivoted in the head and having an operating handle lever, F1, extending upward and forward for convenient grasp of the operator, the cam being so formed and positioned that the plunger is depressed by swinging the handle lever down. A spring, Il, coiled around the plunger and reacting between the lower bearing thereof and a stop on the plunger for the upper end of the spring (the cross-pin, El, hereinafter mentioned), serves to retract the plunger when the lever handle is swung up.Y The upper die as is customary in machines for this purpose comprises two members, I and J, one of which encompasses the other, the

outer member, J, being adapted to yield upward with respect to the inner member in the operation of the upper die with respect to one of the two lower dies hereinafter mentioned, and to be held unyieldingly with respect to said inner member' for coperation with the other of said lower dies.

Upon the base, A, there are mounted two dies, M and N, which are designed to cooperate with the upper die, I J, at the respective limits ofthe oscillation of the upper die, and for the purpose of limiting said oscillation at proper points for such coperatlon, an auxiliary plunger, P, which is mounted in the head, D, for other purposes hereinafter explained, has its lower end projecting in position to be stopped by lugs, A3 and A4, on the post, A1, when the head 1s swung in the two opposite directions, respectively. For accurately determining the stop` positions of the oscillating head, adjusting screws, A5, are set through lugs, A3 and A, respectively, with whose ends the direct collision of the auxiliary plunger occurs.

For the purpose of. locking the two members of the upper die so that the outer member shall not move with respect to the inner one when working in conjunction with the lower die, M, but may so move when working in conjunction with the lower die, N, there is provided a plunger, L, mounted for vertical movement in aboss, A2, which projects from the post, A1, a spring, S, being provided coiled around the plunger, L, below a shoulder, l, and stopped at its lower end on the base to receive the down thrust of the plunger and re-acting to uplift it. auxiliary plunger, P, above mentioned, when stopped against the lug, A3, is directly in line above the plunger, L. Said auxiliary plunger is connected with the plunger, E, by a cross-head pin, E1, set through the plunger, E, and engaging the auxiliary plunger to carry the latter up and down with the movement of the plunger, E. Said cross-head pin, E1, serves, by running in a vertical slot in the side of the bearing of the auxiliary plunger, P, the additional purpose of preventing the plunger, E, from turning in its bearings. The plunger, L, has a finger, L1, projecting horizontally at proper position to overhang the outer member, J, of the upper die when the head, D, is -swung over to position for cooperation of the upper die The with the lower die, il; that is, when the auxiliary plunger, l), is stopped against the lug, 0,3, or the adjusting screw, A, therein. Preferably, the finger is of such vertical width at the part at which it overhangs said die member, J, as to reach from the said lower die engaged by its lower edge to a shoulder, z', formed on a part rigid with the inner die member, l, such shoulder being conveniently ailorded by the lower end of' 'the plunger, E, the inner member, l, of the die being secured to the plunger by being screwed up into the lower end of the latter for making it rigid therewith.

In order to allow some range of lateral swing to the finger, L1, to adapt it to come to proper position for its function above described with dies of different diameters, the spring, S, is connected at one end with the plunger, and at the other end in the seat of the spring in the base, so as to yieldingly resist the turning of the plunger in its bearing and hold the linger, L1, at a position for being encountered laterally by an inner die member of least diameter when the oscillating head swings over for cooperation of the upper die with the lower die, N.

Upon considering the above described construction, it will be seen that upon the depression of the plunger, E, when the oscillating head has been swung over into position for cooperation of the upper die with the lower die, N, said coperation will occur without the outer die member, J, being locked, and said member will be free to yield upwardly along the inner member; but that when the oscillating head is swung over for cooperation of the upper die with the lower die, M, the finger, L1, enters above the outer member, J, of the lower die, and upon the depression of the plunger, E, the auxiliary plunger, P, is thrust down directly upon the upper end of the lower plunger, L, depressing said plunger and causing its finger, L1, to carry the die member, J down with the die member, l, causing the two members to move absolutely together and as one part in their coperation with the lowei' die, M. rlhis direct and positive downthrust given to the die member, J, is assisted by the finger, L1, spanning the entire distance between the upwardly facing shoulder of the die member, J, and the downwardly facing shoulder, z', rigid with the die member, That is to say, the finger, L1, is carried down with the plunger, E, both by the engagement of said finger below the shoulder, i, and above the die member, J, and also by the thrust of the auxiliary plimger, E, upon the lower plunger, L. The two movements being synchronous and equal insure movement of the plunger, L, without any cramping in its vertical bearings which might result from the application of the :force solely upon the outer end of the finger,

Licentie L1, or which might result from the downthrust pressure applied only upon the upper end of the plunger, L, to meet the resistance of the work acting against the under side or" the extended finger, L1.

The boss, A2, is vertically rifted to accommodate the movement of the finger, L1, in its vertical movement with the plunger, L, and such vertical rift may extend through the entire height of the boss, the width of the rift, a2, being sullicient to accommodate the lateral swing of the finger for dies of maximum and minimum diameters.

In practice, it is convenient to make the post, A1, horizontally symmetrical by forining perfectly similar bosses, A2, at opposite sides of the vertical fore-and-aft axial plane. This makes it possible to mount the plunger, L, with its finger and spring in either boss, so as to loclr the upper die for cooperation with either of the lower dies, as preferred.
