Abstract

581,182. Jointing by forging. MOSS, E. W. (Ingersoll-Rand Co.). March 17, 1944, No. 5037. [Class 83 (iv)] Dies.-A method of jointing an externallythreaded member to a body is described with reference to attaching a stem to a drill rod, detachable bits being mounted on the stem. A punch end 26 is formed on the stem that has an axial bore 24 to form a continuation of the bore in the rod. A two-part die 27, 28 has a recess at 29 to grip the rod with its end located in an enlargement 30. A punch 31 has a recessed end that loosely receives the part of the stem that is to receive the bit and supports it for driving into the heated end of the rod on which it forms a bearing surface. The rod is next advanced further between the dies and the enlarged end is closed firmly round the stem, metal being caused to flow into and fill the threads. Two blows are usually sufficient, the rod being given a part turn after the first.
