Filed: 1936-06-18
Abstract: 477,211. Rail bonds. TRIGGS, W. W. (Ohio Brass Co.) June 18, 1936, No. 16957. [Class 38 (i)] The terminal element of a rail bond consists of a hollow head 4 with tubular extensions 1, 3 for receiving respectively the end of the conductor 6 and a copper pin 9 having a head of the same diameter as the extension 3. The conductor end having been inserted, pressure is applied to force the pin against the strands and the shoulder 11 against the end of the extension 3, the pin being thus locked to the head and the extension and head of the pin receiving their final form. To assemble the bond the extension 3 is placed in a hole in the rail (see Fig. 12) and the head is forced towards the rail to expand the extension within the hole and to compress the strands still further within the head.
