Abstract

530,526. Garage lifts. ENGELBRECHT, K., and AUTOMOBILE PARTS & ACCESSORY CO., Ltd. June 12, 1939, No. 17161. [Class 78 (iii)] A U-shaped leg 9, pivoted to the platform of a hydraulic garage hoist to engage a selected recess in the ring of recesses 9B in the base member and thus supporting the platform in its raised position in addition to holding it against undesired slueing, is supported on the arm 15A of a bell-crank when in the horizontal position but is released by the contact of the weighted or spring-mounted arm 15B with the ground, so that it falls automatically by gravity into the acting position whenever the platform is raised. A series of such legs may be used to support the platform at various levels.
