Description: |
| Abstract:
The object of my invention is to produce a machine-tool for upsetting the saw- teeth, which will operate rapidly and more regularly than the work can be done by hand-hammering. The machine consists, essentially, of a frame, a vertical reciprocating shaft, on the lower end of which the upset is formed, and clamping-dies held within the frame and adapted to clamp and hold the saw and support the tooth during the operation of the upset-tool. The clamping-dies may be adjusted by hand, so as to clamp the saw and support the tooth each time a tooth is operated upon, or the clamping-dies may be operated by means of the automatic attachment set forth, so as to automatically clamp the jaws each time the upset operates. The power required is given the upset by means of an eccentric cam at the end of a lever.
Claim:
In a saw-tooth-upsetting machine, the combination of a sawtooth upset having the operating-surfaces inclined to correspond with the front and back surfaces of the saw-tooth, an extension or holder sliding in guide-bearings in the frame and guided in a right line therein reciprocally toward the cutting-edge of the saw-tooth, the said guide-bearings, the said frame, and sawtooth dies having parallel and smooth or rough blade-clamping surfaces and inclined diverging surfaces adjacent the sides of the tooth-point, the said frame serving to support or hold all of the parts of the device. |
