Abstract

536,315. Overwinding. WARSOP. W. Feb. 17, 1940, No. 3044. [Class 78 (v)] [Also in Group XXXII] In dash-pots in which a fluid is byepassed a piston 8 through a longitudinal slot 6 in the cylinder wall; the slot is made adjustable in area by providing a filler 12 which closely fits the sides of the slot. The filler is movable towards and away from the cylinder axis either bodily or swingably by two screws 15 threaded through the slot cover 13 and engaging the filler by rotary and rockable connections. Lock-nuts 18 hold the filler in adjusted position. A flange 19 depends from the cylinder cover 10 to limit the stroke of the piston. The dash-pot may be applied to overwind prevention for hauling plant, the cylinder alone moving for normal retardation, but both cylinder and piston moving when the cage is going too fast, the piston-rod 9 then operating a trip gear to stop the engine and apply brakes.
