Title: Improvements relating to valves for the control of fluids
IPC: F16K13/02
Filed: 1958-08-20
Abstract: 870,804. Valves. GWYNNES PUMPS Ltd., and WAUCHOPE, G. A. July 30, 1959 [Aug. 20, 1958], No. 26743/58. Class 135. A non-return valve for use in a pump delivery pipe to prevent return flow when the pump is closed down, comprises a housing 1, connected by flanges 2 in a pipe-line and an arcuateshaped valve member 3 of e.g. rectangular plan form, co-operable with a complementary seat 6 on an extension 7 of the upstream pipe section. The valve member 3 is convex on its upstream face and formed on its downstream face with a pair of lateral arms 4 mounted on trunnions 5 which extend outwardly from the housing to mount quadrants 12. The quadrants 12 carry counterbalance weights 13 or alternatively may be influenced by an hydraulic dashpot or motor. The axis a of the trunnions 5 is located at a level other than the axis of the conduit which is also the axis of curvature b of the valve member 3 and its seat 6. As shown, the axis a is below the axis b. If the valve is closed, there will, normally, be water under a static head downstream of the valve and no water or water at reduced pressure upstream thereof. Under these conditions, the moment of the pressure acting on the concave valve face about the axis a overcomes the moment of the weights 13 about this axis to keep the valve tightly closed. On starting the pump, the moment of the pressure acting on the convex face overcomes the moment of the oppositely directed pressure acting on the concave face to open the valve and retain it open until the pump again stops. Adjustable stops 9 and 10 limit the movement of the valve in its open and closed positions respectively. In a modified construction the concave face and the brackets are on the upstream side of the valve with the axis a located above the axis b.

Filed: 1931-09-30
Abstract: 380,951. Preventing rattling of doors. PRESSED STEEL CO. OF GREAT BRITAIN, Ltd., Cowley, Oxfordshire, and FERNBERG, E. B., Grey House, Barton, Headington, Oxford. Sept. 30, 1931, No. 27266. [Class 20 (iii).] Relates to antirattle devices for doors, of the kind comprising interengaging male and female members fitted one to the edge of the door and the other to the corresponding edge of the door frame. According to the invention, the interengaging parts are formed of a resilient material such as pressed sheet metal and in such manner that both parts yield by bending without bodily displacement. In one construction, the male member comprises two plates 1, 5, Fig. 1, provided respectively with lateral extensions 2, 6, and inturned resilient lips 3, 7. The plates are connected together and to the door or door frame 9 by screws 10, the hole in the plate 1 for receiving the screw being elongated vertically to permit vertical adjustment of the plate. The female member, Fig. 4, is formed of two similar plates so disposed that a gap is provided between the lips 3, 7, for receiving the male member. In a modification, a compressible rubber block 32 is inserted between the two plates 30, 31, Fig. 11, constituting the male member. The compression is effected by two end-plates 33 which are interconnected by a screw 34. According to a further modification, the male member is bent from a metal plate 36, Fig. 13, to form two grooves 37, 38 having a common boundary wall 39 which engages between the limbs 44, 45 of a female member. The latter is soldered or welded to a plate 43 which is screwed to the door or door frame. In a slightly modified form, the female member is connected by screws to a plate arranged on the opposite face of the plate 36, the holes in the plate through which the screws pass being elongated vertically. Adjustment of the female member to take up wear is thus made possible.
