Abstract

915,459. Pulley blocks. ANSELL, E. P. Nov. 14, 1960 [Nov. 13, 1959], No. 38558/59. Class 78 (5). A block 21 which forms a mounting for an eye 25 on side cheeks 10, 10, of a pulley block, is assembled by being disposed at rightangles to its final orientation and inserted within vertically disposed slots 18 in inner plates 17, 17. The block is then rotated through 90 degrees (this is permitted by slots 23, 23, Figs. 3, 4) and the side cheeks 10, 10 are then fitted in position. The latter have horizontally extending rectangular slots 11, 11 to fit over the ends of the block 21 and so prevent the latter from turning into a position in which it could escape from the slots 18, 18.
