Specification of Letters Patent.
Patented Sept. 1, 1914.
Application nled uarch 5, 1914 Serial No. 822,622.
'which is "adjustable within certain limits,
whereby upon a little yielding at the same time the inner and the outer cutter engage the material for punching the outer circumference as well as the central hole, so that any distortions produced by a non-simultaneous engagement of the cutters with the material are avoided.
The accompanying drawing shows the subject matter of the invention.
The punch comprises a handle a for the reception of the head I). In the latter an automatic ejector is located, which consists of an ejection disk ?1 with guiding-bolt e screwed therein, the bolt being engaged by a spring 7. In the ejection disk a conical boring is provided for keeping the cutter g in place.
- The device is held by a set-screw d in the head, a screw 0 connecting the handle with the head. The improved punch can work with the handle thereon only. The operation is such that, upon thecutting edge of the head having cut the outer circumference of the washer, the ejector presses the spring back, until the guiding-bolt bears with its rear end against the abutment min the boring of the handle a. By the resistance and further pressure, the punchin out of the central hole of the washer is e ected by the cutter 9. According to the thickness of the material, and particularly for india rubber, regulating rings must be inserted between the guiding-bolt e and abutment m. Paper and non-elastic material may be'folded several times, and a plurality of washers can thus be punchedat a time. The w astevmaterial cut out escapes through the boring in the guiding-bolt and "the opening 71,. in the handle. Upon the spring being untensioned, thefinished washer is automatically ejected. The cutter g may vary in size and crosssection, so as 'to punch washers with d ifi'erent central holes therein.
What I claim, is:
In a punch for makin centrally perforated washers, the comblnation of a resilientlymounted automatic ejector, means to limit the extent of movement of the latter, and two concentric cutters, the inner one being removably fixed to and movable with said ejector, substantially as and for the purpose set forth.
