Abstract

189,536. Price, J. Sept. 1, 1921. T-sockets with key wedges.-The T-socket for the blades B and shaft E of a miner's pick is formed open at the upper end A, so that the shaft may be introduced and passed down into the lower taper part F. The blades B have grooves to engage the parts H, and are locked by the key-wedge C, the lower side of which engages a plate D fixed by nails &c. on the end of the shaft E. The end of the shaft with the plate D projects upwardly for about three-eighths of an inch into the key slot G, so that the key C locks the. shaft firmly down in the socket F at the same time that it locks the blade B. Fig. I shows a section and Fig. II an elevation with the parts locked in position by the key C.
