Abstract
749,797. Wire strainers. LAKE & ELLIOT, Ltd., and BROOKES, W. Dec. 15, 1954 [Dec. 31, 1953], No. 36335/53. Class 45. [Also in Groups XXIII and XXIX] An hydraulic tool for straining wires has a ram 3 extending a piston 2 in a cylinder 1 and has a tube 5 extending inside the ram and supplied with oil from a pump contained in the end cap of the cylinder and operated by a handle 32. To extend the ram under no load conditions, a manually-operated valve controlling a passage 45 is opened and the pump is manually operated to withdraw oil from a reservoir A, 18, 19, and deliver it via orifices 10 to the tube 5. Oil at B in the cylinder is exhausted via a pipe 43 and the passage 45 to the reservoir. To retract the ram, the passage 45 is closed by the valve and, on further pumping, oil in the pipe 5 loads the ram and opens a spring-loaded valve 60 to admit high-pressure oil to the part B of the cylinder in front of the piston 2, the ram being thereby withdrawn.
