Abstract

729,796. Mineral-cutting picks. ANDERSON, BOYES & CO., Ltd. Dec. 31, 1953 [Feb. 28, 1953], No. 5695/53. Class 68(1). To facilitate the freeing of the tapered, preferably conical, shank 11 of a mineral-cutting pick from a complementary recess 11a in a pick carrier 16, the head 10 of the pick has a pair of diametrically opposed lugs 14 having convexly-profiled abutment faces 15 on which act the limbs 18 of an extractor 17 inserted between the lugs 14 and the carrier 16. The faces 15 are so curved that a horizontal tangent plane thereto is coincident or parallel with the plane of an annular shoulder 12 at the junction between the head 10 and the shank 11.
