Abstract

1294113 Mineral-mining pick boxes GREENSIDE MACHINE CO Ltd 3 July 1970 [4 July 1969] 33892/69 Heading E1F A pick box for a rockable pick comprises a block 1 in one side face of which is formed a part cylindrical cavity 11 opening to the top surface 15 of the block, a cylindrical swivel block 3 dimensioned to have a sliding fit within the cavity and a socket for receiving a pick 4 that, when in the socket, will extend through the top surface opening, and a cover plate 2 securable to the said side face to cover the cavity and retain the swivel block therein. In the cavity wall opposite the opening thereof into the top wall is a recess 16 for receiving an end portion of the pick when it is entered into the socket to limit the angle of rock of the block. A grease nipple leading into the recess 16 allows packing of the interior of the block with grease to prevent entry of dirt or water into the cavity 11 during use of the block.
