Abstract

1,081,573. Mineral-mining pick & box assemblies. TUNGSTEN CARBIDE DEVELOPMENTS Ltd. April 6, 1966 [March 18, 1965], No. 11442/65. Heading E1F. In a point attack pick and pick box assembly, a box has a solid body for welding to the box carrier of a mineral-mining machine and an integral socketed extension of the body tapering away from the body for receiving the shank of a pick having a head so shaped that, when the pick is fully seated in the socket, the head continues the taper of the extension of the box to the terminal tip of the head.
