Abstract

24,990. Smith, H. E. Oct. 31. Pulley-blocks.-A pulley-block, more particularly for weight-driven petrol-gas apparatus, comprises several pulleys 5 each supported upon a common spindle 4 on several rings of balls 7, the rings being kept apart by thin plates 8 inserted between them. The side cheeks 1 are spaced apart by shouldered bolts 2, the upper one passing through the legs of a suspending hook 3. Between each pulley is a thin plate 6, which has one or both bolts 2 passed through it. The interior surfaces of the pulley bosses are hardened, or the pulleys are provided with steel bushes. The spindle 4 is also of hardened metal.
