Abstract

4869. Perkins, A. March 7. Forging.-Relates to a tool for expanding and contracting finger rings, chain links, short tubes, &c., and consists of a headed plunger, Fig. 3, the stem f of which fits into the bore d of the block a formed with an external cone b and an internal cone c. In expanding a ring it is placed on the cone c and pressed down by the head g. In contracting a ring the block is reversed and the ring, placed in the conical opening c, is pressed down as before. When the head g does not reach the ring, a washer, Fig. 4, is used between the head and ring.
