Abstract
1,220,024. Pulley blocks. ICHINOSUKE NAITO. 24 April, 1969, No. 21126/69. Heading B8B. A pulley block comprises a link chain 6<SP>1</SP> extending around part of the periphery of a grooved rope pulley 6 and incorporating rollers 7 which press the rope 16 into the pulley groove to prevent relative slipping when the pulley 6 moves towards the chain 6<SP>1</SP> as the rope 16 is loaded. The pulley 6 is mounted between side plates 1 and the pulley shaft 4 is slidably mounted in slots 3 in the side plates, the slots extending in a direction towards the midlength point of the chain 6<SP>1</SP>. The rope 16 supports a load through a pulley block 17, one end of the rope being anchored between the side plates at 15 and the other end passing over the pulley 6, between the same and the rollers 7, after which the rope end depends freely from the block. The pulley 6 is directly wound by a handle, and incorporates a pawl-and-ratchet arrangement 8, 9, 12.
