Description: |
| Abstract:
Heretofore in wire-nail machines but one stroke of the heading-hammer could be made with one whole revolution of the main shaft of the machine, which placed a considerable limit upon the capacity of same, while by my improved construction and cooperation of devices I embody, literally speaking, two machines in a single one, as will now be described. Before proceeding further, however, there is one more point of advantage possessed by an improved machine constructed after my invention, and that is, all strain heretofore throw in upon the main shaft during the heading process is removed.
Claim:
A wire-nail machine consisting of a suitable frame or bed-plate, journals secured to the same, within which the triphammer mechanism is mounted, the main shaft geared to a vertical shaft, and which has a tripping-cam mounted upon the said vertical shaft, and a vibrating triphammer operated by said tripping-cam. |
