Abstract

905,928. Builders' hoists. MARTIN HOIST & ENGINEERING CO. Ltd. March 10, 1959 [March 10, 1958], No. 7704/58. Class 78 (3). The platform 18 of a builder's hoist is moved along guide masts 11, 12 by a cable 23 passing from a winch drum 24 over pulley 25, under pulleys 26, 27, on the platform, and over a guide 28 to an anchorage 29. Wheels 14 are provided for transporting the hoist with the mast horizontal, and rods 17 are telescopically extendible from tubes 10a, 10b to form levers which facilitate erection of the hoist. Catch gear.-The weight of the platform normally retains the mounting levers 30 (Fig. 3) of pulleys 26, 27 in horizontal positions, but, in the event of rope 23 breaking, the levers pivot downwardly under the action of a spring (not shown) thereby causing noses 31 thereon to move away from levers 42, so allowing springs 44 to pivot levers 34 upwardly about pivots 35 to apply brake shoes 38 to the masts. Specification 905,929 is referred to.
