Abstract
1,065,106. Hydraulic jacks. OFFICE CENTRAL DE GESTION ET DE CONTROLE O.G.E.C. Jan. 29, 1965 [Feb. 5, 1964], No. 4140/65. Heading B8J. An hydraulic jack comprises an outer cylinder 1 with a piston 2 attached to a rod 3 on a foot 3 1 . A base 4 mounted on the cylinder 1 carries a lug 5 which may be turned about the cylinder 1. A head assembly 6 with a cavity 7 closes thecylinder 1. A control spindle 10is actuated by an adjustable handle 50, Fig. 2 (not shown), to drive a rod 15 with a pump piston 16 in a horizontal cylinder bore 19. A valve system 21 to 28, Fig. 3 (not shown), is so arranged that when the jack is unloaded the pump is double acting, but under load the pump operates by differential single action. A control valve ball 30 may be released by a knob 33 to lower the load which may be supported on the lug 5 or a plate 8 on the head 6. The initial height of the lug 5 may be adjusted by tubular half-shells 47. The hydraulic fluid is contained in a pliable bladder 35 not containing air so that the jack may be used in any position.
