Abstract
413,649. Hydraulic transmission of power. DRUMMOND, A., Ryde's Hill, Guildford, Surrey. Jan. 17, 1933, No. 1566. [Class 69 (ii).] In hydraulically-operated machine tools provided with two or more cylinders, the ends of supply and exhaust pipes for the cylinders, main supply and exhaust pipes K<2>, K<3>, and the ends of pipes leading to control valves are located in a common localized area K, so that any desired cycle of operations may be arranged for by plugging those pipes not required, and connecting the ends of appropriate pipes by readily replaceable pipes. Two cycles of operation and the requisite connections therefor are specified. The apparatus includes means for obtaining a fast initial movement of pistons such as B<3> and a slower final movement, the exhaust from the cylinder passing through a valve such as D, until a device on the piston rod closes the valve, so that the exhaust thereafter passes through a restricted path d. The completion of the stroke of a piston such as B<3> actuates a control value such as E through a trip device which may be constructed as in Specification 413,650.
