Title: Valve
IPC: F16K31/524
Filed: 1941-03-11
Abstract: 548,799. Valves. MARTIN, O. C. March 11, 1941, No. 3323. Convention date, March 11, 1940. [Class 135] A valve device, particularly adapted for controlling hydraulic or pneumatic apparatus used on aircraft has the pressure fluid inlet and the connections leading to the apparatus attached to one face of the valve casing and is arranged so that the valves and actuating shaft may be removed without breaking any pipe joints. Figs. 2 and 7 show the invention arranged to control a double-acting power piston. The device comprises four spring-loaded lift valves arranged in parallel bores closed at both ends by removable screwed plugs and selectively actuated by a manually-actuated cam shaft rotatably mounted in a bore at right-angles to the valve bores. Bores 3, 5, 6 connected respectively to the pressure fluid supply conduit and to the power cylinder are formed in the valve casing parallel to the valve bores and have enlargements 43, 44, 45 to establish communication with enlargements 17, 17a, 19, 19a of the valve bores. The exhaust connection 4 leads to the bore housing the actuating shaft. Each valve bore houses a pressure inlet valve 25 normally held to its seat by a strong spring 29 located by a boss on the valve member and a recess 42 in the cap 16 and an exhaust valve 33 slidably mounted on the spindle 26 of the inlet valve and normally held to its seat by a light spring 32 located by a recess 31 in the inlet valve and bearing in a flanged washer 41 adapted to retain a packing ring 36 in a recess 35 in the exhaust valve. The actuating camshaft is held in place by a detachable cover plate engaging a shoulder on the shaft which cover also serves to retain a packing ring 69 in a recess about the shaft. The shaft has two sets of three cams, of these the central one 48 is adapted to operate the inlet valve while the duplicated cams 49 actuate the exhaust valve. The cams are designed to operate the valves with a movement of 60 degrees from a central position so that a single shaft may be arranged to operate successively three power devices by the continued movement of the single shaft. When the handle 52 is turned from its neutral position one of the inlet valves is opened to connect one or other of the conduits 5 or 6 to the pressure inlet 3 and at the same time one of the exhaust valves is opened to connect the other conduit 6 or 5 to the exhaust connection 4. This connection is established by way of a series of small ports 22a around the exhaust valves, flats 53 on the cam shaft between the two sets of cams and radial ports 47 and an axial bore in the end of the cam shaft.

Filed: 1959-01-30
Abstract: 884,708. Forging axle casings. RUBERY, OWEN & CO. Ltd. April 28, 1960 [Jan. 30, 1959], No. 3327/59. Classes 83 (2) and 83 (4). In a hot-pressing process, particularly for producing vehicle axles, the steps of heating a blank in a furnace, extracting the blank therefrom, conveying it to a press, feeding it into the press, starting the press and ejecting the pressing are performed in sequence under the supervision of temperatureresponsive means at different stages which stop the process if the temperature of the blank is insufficient for satisfactory pressing. Preformed blanks 10, Fig. 3 (not shown), stacked in a magazine are transferred successively by a pneumatic pusher from the upper end thereof into a continuous furnace A having a walking-beam conveyer. At the furnace exit the blank temperature is gauged by an electric eye controlling a pneumatic motor 17, Fig. 4 (not shown), which moves the blank on to a power driven conveyer C leading to a non-driven roller conveyer D. When the blank engages a stop E a pneumatic motor F pushes it transversely off the conveyer where it drops on to loading rails H on a trolley J. The blank turns over as it falls and any loose scale is dislodged. An infrared sensitive electric eye detects the blank temperature and if this is sufficiently high the trolley J transfers the blank into the bottom die L of the press G. As it enters this die the blank engages a member which acts through a cable to start the press. The pressed blank is ejected from the die and transferred by grippers N out of the press or preferably to a second die M where it is coined and after ejection is removed by a conveyer Q to a cooling tunnel R.
