Abstract

173,855. Aitken, G. L., and Milligan, H. Oct. 6, 1920. Catch gear and like safety retaining-mechanism.-In safety devices for mine cages, lifts, hoists, &c. of the kind wherein the cage is connected to a second cage, or to a part of the wind ing-gear, by an auxiliary rope passed over a pulley, the auxiliary rope c is forced against fixed abutments o by blocks n<1> which move outwards when fluid is admitted to the cylinder m by the opening of the valve q caused by the descent of: the pulley d when the main rope breaks. Theplunger l of the valve q is mounted in the holder k for the brake blocks k' which act on the rim of the pulley when it descends. The bearing-block h of the pulley d is slidably mounted in a guide. h<1> and supported by a spring j.
