PUNCHlNG-MACHINE.
Specification of Letters Patent.
Patented Nov. 27, 1906.
Application 1119a 0mm 13,1905 Serial No. 282,564.
To all whom it ntwy concern:
Be it known that I, FRANZ GEORG OLDEN- BURG, a subject of the German Emperor, and a resident of N o. 12 Eimsbuttelerstrasse, Altona, Germany, have invented certain new and useful 1m rovements in a Punching-Machine, of whic the following is a specification.
The invention relates to a punching-machine for punching angular or round holes in angular, round, or plate iron or the like,
which permits the execution of such work in two operations and to punch holes of less di- 'ameter.than the thickness of the material machines in: existence. 7 v
The annexed drawings represent a form of construction 'of the machine above mentioned.
more effectually and'neatly unlike any such Figure 1 shows the longitudinal section of the machine, and Fig.2 the top view.
The punches a and I) (seen to the right of the frame) are conicallypointed and face each other. The exchan eable punch b is attached to a sliding block worked by the eccentric lever c, whereon the points of both punches closely meet each other. ing, and keeping in middle the material to be punchedas, for instance, the two vise-like grippers n, which are acted 011 by the lever I will serve. For this purpose instead of a tightening-screw with right or left threads a stretching and closing arrangement may be advantageously used, which consists of two roof-shaped plates i, which catch the two blocks 72, having saddle-shaped grooves, and the formerofwhich when turned cause the latter two blocks to draw back, forced by springs. The punch .e (shown to the left of the machine) 'is the finishing-tool, under which is an opening to let punched material fall off, and all are as hereunder set forth.
When the machine is in operation, the round or angular bar which is to be punched is firmly held by the above mentioned' stretching or closing arrangement ml. The
lever c is drawn downward, causingtheicompression of the punches over a from the op- For holdholes than the thickness of the material comprising, in combination, a frame, an eccentric lever in said frame working a slidin block, tuo exchan cable punches on sai sliding block, attac ed withstuds, another punch rigidly fastened on the lower part of the frame and lying opposite to one on the said. sliding block, the lower part of the frame having a holev opposite to the other punch on the said sliding block, means for securing and keeping in middle the iron to be punched, substantially as shown and described.
2. Punching-machine for punching angular or round holes in angular, round or plate iron, which need punching with less sized holes than the thickness of the material comprising, in combination, a frame, an eccen tric lever in said frame working a slidin block, two exchangeable punches on said sliding block, attached with studs, another punch rigidly fastened on the-lower part of the frame and lying opposite to one on the said sliding block,'the lower part of the frame having a hole opposite the other punch on the sliding block, two vise-like grippers with suitable arrangement to hold the material in position, substantially as shown and. described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
