Abstract
121,013. Denison & Son, S., Denison, G. H., and Brown, S. C. Jan. 2, 1918. Presses, cylinder-and-piston; ram-retracting devices.-In an hydraulic spring-testing machine, during the downward stroke of the piston A', Fig. 1, the pressure water passing along the pipe E from the pump K moves a sleeve J having a contracted liquid passage, so that it closes a port H<2>. When the pump is reversed or put into the neutral position, the spring C under test returns the piston A', the water in the cylinder moving the sleeve J to uncover the port H<2>. Part of the water passes to the pump if this has been reversed. The passage through the sleeve J may be provided with a spring-controlled valve. In a modification, the escaping fluid supplies the underside of the piston through a non-return valve N, Fig. 2, and the piston is held in its uppermost position by a spring-controlled sleeve O closing a port P until pressure is applied above the piston.
