Abstract

1,250,858. Mineral-mining pick mounts. CARMET CO. 31 July, 1970 [1 Aug., 1969], No. 37122/70. Heading E1F. A mount for locating a mineral-mining pick 4 on driven means of a mineral-mining machine comprises a pick-holding block 2 secured to the base 8 of an adapter 6 having a projection 10 extending substantially perpendicularly from the under face of the base to be non-rotatably secured in a recess 14 in holder 13 mounted on the driven means. The block 2, base 8, holder 13 and driven member may be united to the appropriate, associated part by welding. The projection 10 and recess 14 may be rectangular in cross section and secured together by a resilient pin 22 entered into aligned bores 20 therein when the projection is located in the recess.
