1662. Walker, F. W. Jan. 21. Forging.-Relates to the means and tools employed in producing washers, rings, tyres, hoops, and polygonal rings for heavy nuts, as described in Specification No. 29,333, A.D. 1896. The ingot or bloom d, placed in a die g in a hydraulic press, is first acted upon by a tool h, Fig. 2, to spread the edges of the ingot into the cavity g<1> of the die, as shown in Fig. 4. The ingot is then acted upon by a recessed flat face tool i, Fig. 4, forcing the metal more into the cavity g<1> and leaving the nose d<1> projecting from the end of the ingot. The metal of the nose d' is then pressed back by a tool k, Fig. 6, into the ingot, completely filling the cavity g<1>, and finally the ingot is forced back by a tool l detaching the ring &c. from the ingot. The first tool h may be replaced by a tool m producing an annular ridge of metal which is afterwards forced into the recess g'.
