Description: |
| Abstract:
The nature of the said Jerimiah H. Pierson's invention consists in gripping that part of the wire which is to be formed into a screw blank or a rivet by means of jaws, and then sliding-these jaws along or by and in contact with the surface of a rest-plate (through a hole in which plate the wire is fed) to cut off the length required, the one edge of the gripping jaws and the hole in the plate constituting shears for cutting the wire, and by this motion carrying the end of the piece of wire cut oil sufficiently far to rest against the rest plate, which is a permanent part of the machine/preparatory to striking up the head.
Claim:
Cutting off the wire to be formed into a screw-blank or rivet by the sliding of the gripping-jaws after the wire has been gripped by them, when this is combined with the permanent rest-plate or head-block through which the wire is fed to the jaws, which acts as the permanent shear for cutting of the wire, and as the permanent rest or bed for the blank-or rivet when under the operation of the header. |
