Abstract

183,375. Stoner, C. A., and Stoner, N. D. Aug. 27, 1921. Pulley-blocks. -- Comprises a construction of pulley-block of the type in which the sheave is enclosed in a casing formed of two side plates held together detachably by bolts. In the present construction the casing is formed of L-shaped and flat members 3, 2 respectively, held in spaced relation by bolts 5 and the hook-carrying sleeve 6. The side walls of the casing overlap the periphery of the pulley to prevent the hands of the operator from being caught between the ropes and the pulleys. The L.shaped member is formed with perforations 11 through which the ropes pass. and with a central perforation 10 through which the hook 9 passes to the pulley-shaft by which it is supported. When used fur sheaves with four or six pulleys, each member 2, 3 of the casing is L-shaped to give a double thickness of metal at the top of the casing.
