Mechanical power forging machine

Mechanical power forging machine

This is an early example of the type of forging machine patented by W. Ryder in 1841, and used for rapid forging of small pieces.

A number of dies or swages of any desired form are fixed in the machine in pairs, the lower dies being fixed in the framing, with screw adjustments, while the upper ones are moved very rapidly up and down by means of eccentrics on the upper shaft, which is driven at about 600 rpm. The pairs of dies are generally arranged in a series of varying diameters. One of the lower dies is moved up and down in concert with the upper die, by means of a cam on a short shaft below; these two tools form cutting dies or shears. Such machines forge suitable objects with great rapidity, and of almost standard dimensions; some examples of such forgings are shown.
