Abstract
621,020. Lifting vehicles. VILLARS, J. Jan. 26, 1945, No. 2066. Convention date, March 30, 1944. [Class 78 (iii)] In apparatus for raising vehicles of the kind in which the wheels rest on two braced rails supported by four vertically movable members A ... D actuated by a single motor M through transmission members 11, 12, 13 located below ground level, the transmission members are arranged along three sides of a rectangle formed by the vertically movable members. Each member A ... D is a screw 1, Figs. 3 and 4, on which is mounted a nut 4 turning in bearings 6, 7 mounted in a fixed casing 5 and resting on a ball-bearing 8. The nut on each screw is driven by a bevel gear 10 on the end of a transmission member. In the case of the screw A the gear 10 is connected to the shaft of the motor M. The upper end of each screw is secured rigidly to a plate 16 which is welded to two girders 15 forming part of a rail. Sheets 17, 18 welded to the flanges of the,girders and a sleeve 19 welded to each sheet 18 form a fluid-tight casing. The sleeve 19 is the uppermost of a series of telescopic tubes. connecting the rail and casing 5. The screws &c. may be replaced by rack-and-pinion mechanism.
