Abstract

22,764. Maurice, A. H., and Barrow, H. G. J. Oct. 22. Picks.-A removable pick blade A for use in combination with the type of pick head described in Specification No. 2421, A.D. 1903, aud to which it is fixed by a wedge W, hai two grooves B, B' cut across the back of the blade at right-angles to its principal axis into which the top lugs C of the pick head S enter. These grooves are placed one on either side of, and at equal distances from, the centre of the blade. The lugs C thus countersink into the back of the pick and obviate undue projection of the head of the socket beyond the blade and prevent any movement of the blade in the line of its principal axis.
