[Fig. 3073] represents a finishing machine for horseshoes. The bars of iron are rolled with the creases (for the nail heads of the finished shoe) in them. The blanks for the shoes are then cut to length and bent, and the nail holes punched. The shoes then pass to a machine, [Fig. 3073], which consists of a frame a b, carrying the roll c, above the table d, and a second roll, not shown in the cut, but being directly beneath c, there being between these two rolls sufficient space to let the dies (which press the shoes into shape) pass.
These dies rest upon the table d, and are carried around upon it in a direction from left to right of the chain h, to the links of which the dies are attached. This chain is operated by the vertical shaft j, having a pulley for belt power at k.
As each die approaches the rollers, a shoe (cut to length, creased, and punched as already described) is placed on it, and on reaching the rolls the shoe is pressed into form on the die by the rolls, the bottom roll serving as a rolling bed so as to reduce the friction that would be due to a sliding motion on the bottom of the die. The top roll c, which presses the shoe into the die is driven by power.
