Abstract

418,313. Mine chocks. BATES, S., The Grange, Prudhoe-on-Tyne. April 27, 1933, No. 12328. [Class 20 (ii).] A chock-member for use in mines is formed of two hollow longitudinal parts held together at the ends by caps, the removal of which, allows the parts to slide laterally and the chock to collapse. The chock-member may be formed from a tube a split longitudinally and held together by endcaps c, the abutting edges d being disposed at an angle to the horizontal, so that removal of the end caps allows the chock to collapse. The abutting edges of the parts may be inturned to form flanges, and the tube may be of square or other section.
