Abstract

680,950. Pick mounting endless chains. MEUTSCH. A. July 19, 1950 [Jan. 20, 1950; Feb. 1, 1950], No. 18061/50. Class 68(i) To enable one or more picks to be mounted in a holder 1 on a link of an endless chain, the shank 12 of each bit has a conical taper and fits into a complementary shaped cavity 2 in the holder, the cavity widening in the form of a hollow cone in the direction of the holder's advance, the axis of the cavity being parallel to this direction. The bit head 13 is' set at an angle of between 90 degrees and 100 degrees to the axis of the shank. To prevent rotation of the bit a slot is formed in the holder running parallel to the axis so that the faces of the slot support the bit. The cutting tip 15 of the bit is held in position prior to being soldered therein by a retaining body of solderable unalloyed steel. formed of two legs 25, 26 bent at an angle to each other of less than 90 degrees, one leg being secured by riveting or being screwed into the shank, whilst the other leg bears against the cutting tip to hold it in position.
