To all whom it Wear/y concern.-

Be it known that I, JULIUs Gr. BREITEN- 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 and Like Purposes, of which the following is a specification, reference being had to the accompanying 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 move ment toward and from each other in successive processes, such as are re uired in making buttons composed of a p urality of elements which are assembled and clenched together in the processes performed by the dies.

The purpose ofthe invention is to rovide improved means for causingv one of t e dies which has a yielding member to act as if said member were unyielding when 006 erating with one of two 0 posed dies with w ich it is alternately broug t into cooperation, while permitting it to act by the yielding of its yielding member when it cooperates with the other of the two opposed dies. It consists of the features of construction set out in the claims.

In the drawings, Figure 1 is a side elevation of this improved machine. Fig. 2 is a section at the line 2 2 on Fig. 1, showing the 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 the upper die in line with the other of the two lower dies. Fig. 4 is adetailsection at the line4 4 on Fig. 1.

The structure shown in the drawings comprises a press-standard A, having mounted in its upper part a vertically-reciprocating head B, normally upheld by a spring 0 and thrust downward for cooperation of the dies by a cam-lever D, whose action will be obvious from the form shown in Fig. 1. The upper die carried in the reciprocating head B comprises a fixed member E and a yielding member E.

F is an oscillating carrier fulcrumed at f on the bed A of the standard and carrying the two lower dies G and H, the range of oscillation of the carrier being such as to bring the two dies into line, respectively, with the upper die at the two limits of such oscillation. Any suitable stops, as the pins J, encountered by the carrier at the two limits, respectively, of the oscillation of such carrier determines the position of the respective dies G and H forcooperation with the upper die.

On the fixed 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 reciprocating head B, (this being, however, merely incidental,) such flange being in position overhanging the yielding member E of the die and constituting a stop limiting the upward yielding movement of said member. The interval between the flange and the said yielding member when the latter is at its lower position corresponds to the range of yielding movement.

K is a rock-shaft mounted vertically on the standard A back of the dies. Preferably this rock-shaft is tubular, constituting a sleeve, and is mounted for its rocking movement on a fixed vertical shaft L, whose lower and u per ends are engaged, respectively, with the bed and overhanging head portion of the standard. The rock-shaft K has an arm K of suitable length to be swung against the side of the upper di'e'and of suitable width vertically at its end to enter and occupy the interval between the flange E and the yielding member E of said die. The tubular rock-shaft K has a range of vertical movement on its supporting rod or shaft L to permit it to move with the upper die in the reciprocating action of the latter, so that when the arm K is engaged between the flange E and the yielding member E of the die at the upper position of said die the downward movement of the die carries the vertical rock-shaft with it, and the presence of the end of the arm K between the flange E and the yielding member E prevents the yielding of the latter and causes the die to operate as if it were a single rigid element.

A spring M is coiled around a fixed shaft L of the rock-shaft, the latter having its cavity enlarged to form a recess or chamber for the spring at the lower end, and the upper end of the spring is also engaged with said rockshaft, as seen in Fig. 4, the lower end of the spring being stepped on the bed and also en.

gaged with the latter. The spring thus operates to yieldingly uphold the rock-shaft and also to yieldingly resist its rocking or swinging action about the shaft L and tending to restore it to its elevated position and also to the position at which the arm K rests against the side of the upper die. The rock-shaft K has near the lower end another lever-arm K and the oscillating die-carrier F has an arm or finger l which encounters the lever-arm K of the rock-shaft when the carrier is swung away from the position at which the die G is in line with the upper die, and by such encounter and in the further swinging movement of the carrier swings the rock-shaft in direction to carry the arm K out from between the flange E and the yielding member E of the upper die, and at the opposite limit of the oscillation of the carrier, being the po-v sition at which the die H is in line with the upper die or lever-arm or finger F of the carrier, stands at right angles to the lever-arm K of the rock-shaft, and thus locks the shaft positively in the position to which it has thus been forced, the relation of the parts preventing any tendency of the spring M to react against the carrier to reverse its movement or displace it from its proper position for registering with the upper die. I In this position, therefore, it will be seen that the yielding member of the upper die will be free. to yield when that die is depressed for cooperation with the lower die H and that when the die-carrier is again swung back to its first position the arm K of the rock-shaft will be restored to position between the flange E and the yielding member E and insure the rigid action of the upper die, as already described.

In order to prevent the arm K from swing, ing past the position of the upper die when the die is removed, as in changing dies, and

' so being left through oversight on the wrong side of the die when the latter is replaced, there is preferably provided a little 111g K projecting from the back side of the rockshaft K, which will collide with the standard A to limit the swing of the arm K, as will be easily understood from Fig. 2.

I claim 1.
