STAMPING-PRESS.

SPECIFICATION forming part of Letters PatentNo. 518,080, dated April 10, 1894. ppl i n filed October 5, 1893. Serial No. 487,244. (No model.) Patented in Germany April 7, 1889, No. 49,580-

To aZZ whom, it may concern:

Be it known that I, LOUIS SOHULER, asubject of the Emperor of Germany, residing at Goppingen, in the Kingdom of Wiirtemberg, Germany, have invented certain new and useful Improvements in- Stamping- Presses, (for which I have obtained Letters Patent in Germany, No. 49,580, dated April 7, 1889,) of which the following is a specification.

In stamping presses in use heretofore and provided with a movable support for the article to be stamped, the said support israised by means of cams and descends under the action of its own weight. In stamping presses of this kind the article produced is always lifted off toward the top, and thus the table when descending must also accomplish this lifting off of the article. In such cases where the metal being stamped is thicker than the space between the male and female dies the vessel produced, with the female die and the support remains suspended from the-male die and remains in the raised position until the male die during its upward movement is forcibly removed from the article. By this time the main axis has turned about ninety degrees and the support drops back upon the cams, and in doing so injures and frequently destroys the entire machine.

The object of my invention is to provide a new and improved stamping press in which the support for the lower die is compelled to descend in the same manner as the cams descend that is used for raising it.

In the accompanying drawings, Figure 1 is a front view of my improvement as applied to a stamping-press parts being shown in section on the line l,1, Fig. 2, and others omitted, and Fig. 2 is a side-view of the con struction shown in Fig. 1, parts being broken out.

Similar letters of reference indicate corresponding parts.

The support a for the lower die is guided in its vertical movements by the slotted standards b b, in which the tubular pivots c of said support travel vertically. An anti-friction roller (1 is mounted on the outer end of each pivot beyond the outer plane of the standards, as shown in Figs. 1 and 2. The mainshaft 4. carries the driving-wheels eat the ends and the cams h acting on the rollers mof the support a. To the spokes of each wheel e a curved flanged track f is fastened, the curvature of which coincides with the curvature of .the edge g of the cams or cam h, on which edge 9 the rollers m travel during the time v that the supportadescends. The tracksfare provided along the upper edges withv flanges which extend toward the anti-friction rollers d.

Fig. 2 shows the support in the highest position and the shaft 7;, Wheels e and cam h being rotated in the direction of the arrow. As the wheels continue to move in that direction the flanges of the tracksfbear down on the rollers d and compel the same, with the support a, to descend, the rollers m constantly remaining on the cams it. As shown,the tracks f are only of such length as to run ofi the rollers 51 by the time the support a has reached its lowest position.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is 1. A stampingpress, constructed with a cam-shaft, a support for the bottom-die, cams for raising the said support, wheels on the cam shaft, curved tracks fastened to said wheels, and projections on the die support, on which projection said curved tracks can act, substantially as set forth.

2. A stampingpress, constructed with a cam-shaft, a vertically movable support for the lower die, vertically-slotted standards between which said support is guided to move vertically, cams'on the cam-shaft for raising the support, rollers pivoted on said support, wheels on the ends of the cam-shaft, and flanged curved tracks attached to said wheels, which curved tracks, when the support has reached its highest position, bear on the rollers of the support andpress the same and said support downward, substantially as set forth.

In testimony that Iclaim theforegoing as my invention I have signed my name in presence of two subscribing witnesses.

LOUIS SOHULER.
