Abstract
877,869. Hydraulic jacks. TOUSSAINT & HESS HYDRAULISCHE HEBEZEUGFABRIK G.m.b.H. Aug. 21, 1959 [April 24, 1959], No. 28709/59. Class 78 (3). [Also in Group XXIX] Hydraulic apparatus comprises a cylinder 10, Fig. 1, at least two telescopic pistons 14, 20 movable in the cylinder, the outer piston 14 being shaped to form a pair of chambers 17, 18 with the cylinder, one of the chambers being in communication with the interior 21 of the outer piston, and a valve 27 which can be opened to establish communication between the pair of chambers. The cylinder may be supplied with fluid pressure from a pump 28 when a by-pass valve 32 is closed, the fluid entering a space 18 to move the piston 14 upwardly. During the upward movement of the piston, fluid in the chamber 17 passes through ports 22 to the interior 21 of the piston 14 to move the piston 20 relative to the piston 14. When the by-pass valve 32 is opened, the pistons are returned to their inner position and any fluid which has passed the seal 25 of the piston resulting in a higher pressure in the chamber 17 than in the space 18 can then be passed to the space 18 by opening the needle valve 27. In another embodiment having three telescopic cylinders 14, 33, 20, Fig. 3, the spaces 18, 21, 36 between the pistons are interconnected by valves 43, 44 which are positively opened when the pistons are in their inner positions by projections 50, 52. In a further embodiment, the spaces 18, 21 are interconnected by a manually adjustable valve and the spaces 21, 36 by a ball valve.
