Abstract
780,383. Hydraulic lifting jacks. SKYHI, Ltd., and STEAD, A. H. Dec. 6, 1955 [Dec. 6, 1954], No. 35241/54. Class 78 (3). As shown, Fig. 2, the pistons of rams 17, 18, pivoted at 19, 20 to side plates 12 of a base frame, are joined by a knuckle joint at 21 forming a lifting head. A pump 16, operated by a hand lever 15 in one of two sockets 23 and having a manually-operated release valve 27, supplies liquid to the ram cylinders through pipes 22 (Fig. 1, not shown), along the side member 12 and through rotary couplings at the pivots 19, 20. Specification 576,692 is referred to.
