Abstract

379,979. Hydraulic transmission of power. FORTUNA-WERKE SPEZIAL. MASCHINENFABRIK AKT.-GES. and LOOSE, J., Cannstatt, Stuttgart, Germany. Feb. 10, 1932, No. 3966. [Class 69 (ii).] Hydraulic or other fluid pressure mechanism for reciprocating machine tables is provided with a main reversing valve, and an auxiliary pressure-operated piston moved at an adjustable speed to cause a dwell at each end of the table stroke ; means may also be provided to dispense with the dwell. In the form shown in Fig. 1, the main valve 10 operated by stops 11 is connected by conduits 8, 9 to a chest 7, connected by conduits 5, 6 to the table cylinder 1. At the end of a stroke, pressure fluid moves a piston 13 at a speed determined by an adjustable throttle 16, the cylinder 1 not being supplied until the piston 13 has uncovered the conduit 5 or 6. Spring-controlled valves 23, 24 are opened by the exhaust from the table cylinder 1 ; when it is desired to dispense with the dwell, these valves are held open by a cam member 28. In another form, the valves 23, 24 are dispensed with, a main valve 31<1>, Fig. 3, being connected with an auxiliary valve 31<11>, the two valves being integrally or otherwise connected.
