Abstract

735,113. Coal-cutter picks. JOY-SULLIVAN, Ltd. May 7, 1953 [May 7, 1952], No. 11559/52. Class 68(1). A duplex cutter pick is formed of two like parts 62, the parts being joined by riveting, brazing, welding, or the like, or being so assembled and secured in the box of a chain link as to form a duplex pick. Positioned on the parts, correctly to relate them, are interengaging pin and socket or like locating means 4, and the shank of each part is stepped at 8 and 9, or at least one of the parts has a projecting pin to position the pick in the link box. The parts may be shaped so that, when assembled, the resultant pick has the same shape as the duplex pick described in Specification 735,114.
