Abstract
1,042,877. Mining pick-securing means. AUSTIN HOY & CO. Ltd. Nov. 9, 1962 [Nov. 13, 1961], No. 40550/61. Heading E1F. The securing means consists of a latch housed in the side wall of a pick box and resiliently biased out into the pick shankreceiving bore of box. The latch is such that when a pick shank is inserted into the bore the shank pushes the latch into the wall clear of the bore until the latch can emerge from the wall to enter a notch in the pick shank to lock the shank in the box when the notch comes into alignment with the latch. To allow of release of the pick the latch is withdrawn from the notch by acting on means provided on the latch for such a purpose. Two preferred embodiments are described.
