Abstract: 618,545. Valves controlled by pilot valves. TRICO PRODUCTS CORPORATION. Sept., 16, 1946, No. 27752. Convention date, Sept. 19, 1945. [Class 135] [Also in Group X] A control valve for pneumatic motors is provided with spaced ports 35, 36, Fig. 3, and valve closure elements constituted by members 55, surrounded by sealing rings 45, and carried on a lever 46, and when the latter is rocked by means of a knob 53, one closure is opened while the lever fulcrums about the other closure. The rings 45 are of rubber &c. The invention is shown applied to an automobile windowoperating apparatus comprising a jack and a pair of relay valves 22, Fig. 4, situated between the control valve and the jack. Suction from the manifold of the vehicle engine is applied to chambers 63 in both relay valves where.it can act on pistons 71, 75 constituting shuttle valves. When the control valve is actuated, air passes through one of the ports 35, 36 and a conduit 82 to the top of the appropriate piston 75 to force the shuttle valve down against the action of its loading spring 73 with the result that. piston 75 closes on its seat 60 and shuts off communication between the suction source and a chamber 65 leading to one side of the jack, and air from a chamber 72 open to the atmosphere passes the now-open piston 71 and flows into chamber 65 and to the jack to actuate the latter.

Title: Improvements in electric tumbler switches
IPC: H01H9/16
Filed: 1947-10-22
Abstract: 629,051. Tumbler switches. SIMPLEX ELECTRIC CO., Ltd., and HUNT, J. J. H. Oct. 22, 1947, No. 28199. [Class 38(v)] A switch comprises an operating lever 22 rotatable on a spindle 21 and,having face cams 25 formed on the side of its hub 24 such that as the lever 22 is moved, the cams 25 engage ribs 31 of a block 30 to move it axially along the spindle 21, the block 30 having a flat portion engaging the base 10 to prevent its rotation. Loosely mounted on a cylindrical portion 33 of the block is a bridging contact 34 which in the " on " position of the lever is pressed by a pair of springs 36 against a fixed contact pair 15. To ensure that one end 37 of the contact 34 leaves its fixed contact before the other, the springs 36 may have different strengths or, as shown, the block 30 may engage the contact 34 off-centre. In the opening movement, the end 37 of the contact 34 is arrested by an abutment 42 after moving through a small distance sufficient to prevent re-striking of the arc, after which the contact 34 pivots about the abutment 42 whereby its other end moves through a greater distance for isolation. In the embodiment described, the switch mechanism is duplicated on either side of the lever 22 and controls a pair of contacts 34. Should the springs 36 acting on one contact 34 be stronger than those acting on the other contact 34, the block 30 controlled by the weaker :springs will be :arrested by a washer 38 and then the other block will be moved, the lever 22 being slidable on the spindle 21 to permit this. The switch operation may be assisted by a nose 28 on the lever 22 engaging a spring- pressed member 29 in the base. The lever 22 passes through an indicator plate 40 slidable between the cover 13 and a platform 41 carried by the body 10 whereby " on " and " off " legends are brought opposite an aperture in the. cover.

Abstract: 860,761. Valves. DOWTY MINING EQUIPMENT Ltd. Sept. 5, 1958 [Sept. 6, 1957], No. 28247/57. Class 135. A valve arrangement for an hydraulic pit prop comprises an auxiliary valve and a main valve arranged to be opened in succession with lost motion between them by a unidirectional pull on a wire, the auxiliary valve, when opened, serving to reduce liquid pressure normally keeping the main valve closed and also capable of serving as a relief valve to open automatically at a predetermined pressure. The spring- closed main valve member 12 is slidable in a cylinder 8, of larger cross-sectional area than the seating 9, so that high pressure liquid trapped between the piston head and ram tube B acts via axial bore 17 on the top face of the valve member to maintain it closed. The spring-closed auxiliary valve 23 is actuated with lost motion through screw 33 and coupling 32 by a pull wire 27 to relieve pressure above the main valve member and enable it to open under the resultant liquid pressure differential to exhaust liquid through ports 11. The auxiliary valve may also act in the manner described in Specification 753,532 as a relief valve. If the ram is not under pressure the main valve will not operate as described above and to enable it to be moved the main valve may be opened directly, with lost motion, by the pull wire by virtue of a guiding stem 18 of the auxiliary valve being fitted with an enlarged end piece 21 which is adapted to engage a projection 22 on the main valve member.

A projectile firing device comprises a guide rod 21, a hollow body 22 fitting slidably on the rod, a piston 30 fitted to slide in fluid-tight manner in the body 22 so as to form an extensible explosion chamber in which is disposed the firing charge contained in the case 35b of an auxiliary projectile 35. A spring-loaded striker 25 which can be instantaneously released from the cocked position by withdrawal from the body 22 of a transverse pin is adapted to fire the auxiliary projectile 35 so that the ball 35a thereof moves backward into the aperture 33 of the piston 30 and the case 35b moves forwards carrying the hollow body 22 and projectile 23 therewith. The ball 35a presses grease contained in piston aperture 33 into an opposite piston aperture 32 which cushions the reactions of the ball with the piston and also the latter with the end of the guide rod 21 and also acts to seal the rear end of the explosion chamber. When the hollow body has moved forward sufficiently for apertures 36 therein to be connected with the explosion chamber the explosion gases may expand into a decompression chamber 37 from where they may pass into the atmosphere and so reduce noise. The rod may be held in the muzzle of a fire-arm or by a support fixed in the ground. In another embodiment the guide rod is connected to the projectile and the hollow body is fixed. In a further embodiment a fixed guide rod is hollow and contains the spring-loaded striker which moves forwards on release to fire an auxiliary projectile housed in the nose of the hollow body. The article may be operated by electrical, electromagnetic, or pneumatic means.

Abstract: 1,183,078. Disc brakes. ALFRED TEVES G.m.b.H. 20 June, 1967 [16 Sept., 1966], No. 28429/67. Heading F2E. A slack adjuster for an hydraulically operated disc brake includes a cam within the operating cylinder and rotationally spring-biased to take up the slack. When the piston shown is advanced by fluid pressure any gap which might open between the spring disc 8 and the surface of an eccentric cam 6 is taken up by rotation of the cam due to a helical spring (7, Fig. 2, not shown) mounted on a shaft 5. When the brake is released the return force is sufficient to collapse a spring disc 8 to provide brake clearance but insufficient to rotate the cam. Mechanical operation of the brake is effected by a lever which rotates a shaft having an eccentric portion 5. The eccentric disc can be restored to its initial position during friction pad replacement by reverse rotation of shaft 5 and thus the helical spring thereon.
