MULTI-TERMINAL RAIL BONDS AND TRACK DRILLS Forestalling the now rapidly growing demand for largecapacity rail-bonds and bonds with greatly increased contactareas, the American Steel & Wire Company has produced anew line of which one style, the Triple Terminal bond, isshown in the accompanying cut. One-half-in. copper studs, two, three or four to a terminal,are compressed into corresponding bottomed holes drilledinto the outside of the head of the rail. The contact areasthus provided are several times the maximum areas possiblefor single-stud bonds. Under repeated hammer blows the. TRIPLE TERMINAL BOND copper at the orifice of each hole becomes so dense and thetwo metals are forced into such intimate contact that thebond holes are sealed completely and permanently. Justwithin the opening to each hole a groove in the steel, cutwith a milling tool, permits the copper under compression toform an anchoring ring which also effectively supplements theexternal sealing of, and positively excludes all moisture from,the holes. The number of terminal studs is proportionate to the capac-
