Abstract: 371,603. Hydraulic motors. WERNER AKT.-GES., F., 58, Fritz Wernerstrasse, and JUNGE, C., 20, Kaiserallee, both in Marienfelde, Berlin. April 22, 1931, No. 11923. [Class 69 (ii).] The reversal of the movement of a hydraulically operated carriage of a machine is effected by means of a single rotary and axially movable valve. In one form, a valve 2, Fig. 1, when in the position shown allows liquid to pass from an inlet 3, through ducts 4, 5, 6 to move a piston 1 to the left, the exhaust passing through ducts 7, 8, 9; the valve is maintained in position by pressure acting on one end through 10, 11. When the piston 1 nears its end position, the valve is turned by action on a member 21, to bring a passage 15 into communication with a pressure inlet 18, and a passage 12 into communication with an outlet 17 ; the valve is then moved axially into its other end position, shown in Fig. 4,' so that the inlet 3 connects with the duct 7 to reverse the motion of the piston 1. In another form, a valve 102, Figs. 7 and 8, has a chamber 113 engaged by a fixed member 114 ; axial movement of the valve caused by the piston 101 at the ends of its stroke reverses connections to pressure and exhaust on opposite sides of the member 114, so that the valve is then turned to reverse the pressure and exhaust connections of the cylinder containing the piston 101.

Filed: 1945-05-18
Abstract: 594,428. Feedwater supply systems for steam boilers. STANLEY STEAM MOTORS CORPORATION. May 18, 1945, No. 12593. Convention date, May 22, 1944. [Class 123 (ii).] [Also in Groups XXVI and XXVIII] A steam power plant includes a pair of prime movers operable by steam generated in a boiler supplied with feedwater by at least two feedwater pumps, means for selectively driving one of the pumps from one or the other prime mover, and means for driving one other of the pumps solely from one of the prime movers. In the example, a tube or flash boiler 10 is supplied with feedwater by two pumps 21, 22, one (21) of which is driven directly by a steam engine 14, the other (22) being driven either by the engine 14 or through gearing 37, by an exhaust steam turbine 16, whichever has the greater driving speed, as permitted by an overrunning clutch 75. Each pump may be of the reciprocating type (see Group XXVIII) and has an electromagnet (45 or 46) which controls a suction valve, selectively to render the pump operative or inoperative to supply water to the boiler. The pump 22 supplies water continuously, unless the steam pressure exceeds a certain value, when a pressure responsive device 57 opens contacts 58 thus de-energizing electromagnets 45, 46 and rendering both pumps inoperative. Simultaneously the circuit to a burner &c. heating the boiler 10 is broken until the pressure falls again. If the supply of feedwater from pump 22 is insufficient, the boiler temperature rises and causes a temperature responsive device 47 to close the contacts 52, 53 (as shown) thus completing the circuit connecting a battery 59 to the electromagnet 45 and rendering pump 21 operative. A second overrunning clutch 92 connects the turbine to an electric motor 90, the faster of the two driving a blower 35 supplying air through a venturi 32 housing a carburation device 33 containing fuel, and a spark plug 34. The motor 90 serves as an auxiliary draught means preventing the blower speed falling below a predetermined minimum so that at very low speeds of the engine 14, the boiler temperature increases until contacts 55, 56 are opened to shut off the burner. The exhaust steam from the turbine is passed through a feedwater heater 18 and thence to a condenser (not shown) and so returns to a hot well 20. The invention is described as applied to a steam vehicle.
