Title: Improvements in or relating to valves for hydraulic shock absorbers
Inventor: MOORE HERBERT WILLIAM
IPC: F16F9/32
Filed: 1950-05-25
Abstract: 688,286. Hydraulic shock absorbers. NEWTON & BENNETT, Ltd. May 24, 1951 [May 25, 1950], No. 13119/50. Class 108 (iii). A valve for a hydraulic shock absorber of the kind comprising a flexible disc valve having a facial seat-engaging surface complementary to a seating, is characterized by means permitting controlled movement of the seating under hydraulic pressure in one direction while in seated relation with the valve disc whereby, upon cessation of such controlled movement the valve disc by further flexing can separate from the seating to permit hydraulic flow in one direction and by resilient means permitting separation of the seating from the valve disc under hydraulic pressure in the opposite direction to permit the opposite direction of flow of the hydraulic fluid. In the arrangement shown, as applied to a valve controlling fluid flow between a shock absorber cylinder a and a reservoir cylinder arranged concentrically thereof, the cylinder a is provided with an upwardly domed end pressing c having apertures c3 and radially spaced projections c4 which engage the lower end of the reservoir cylinder. A spring-loaded tube f projecting through the dome of the pressing c carries a seating disc g which engages an annular valve disc e. Upward movement of the tube f is limited by a spring abutment j. Leakage through the tube f is determined by a wire k. In operation, increasing fluid pressure above the valve, flexes the disc e downwardly, the seating g moving with it, until the latter engages a shim h and the seating and disc separating to a valve-open position. Fluid flow in the opposite direction lifts the seating g which then functions as a plate valve relative to the valve disc e. The valve opening in the downward direction of fluid may be modified by causing the seating g to flex over a curved backing member on the shim h. The number and thickness of the shims may be varied. In a modification, Fig. 3 (not shown), the pressing c is flat-bottomed and is threaded to receive an adjustable plug carrying the spring-loaded seating.

Patent GB-171958-A (GB)
Title: Improvements in and relating to display apparatus
IPC: G09F11/295
Filed: 1921-05-09
Abstract: 171,958. James, C. C., and James, G. C. May 8, 1920, [Convention date]. Reel and web apparatus.-Relates to advertising-apparatus in which a display sheet is wound off one roller on to another and comprises improvements in means for automatically stopping the sheet when it reaches certain positions. The apparatus is started by a hand-switch after each stop. A motor 14 drives directly either an upper roller 9 or a lower roller 10 according to its direction of rotation, the 'selecting-means consisting of two ratchet tooth clutches 18, 19, either of which pushes the other into gear when itself thrown out of gear by riding up over its mating teeth when it is turned in the non-engaging direction. The motor drives the rollers 9, 10 through the spring-pressed friction discs 28, 35, so that sudden stoppage of the rollers at a definite position bf the sheet 13 does not prevent the motor and its gearing from coming to rest slowly. Means for stopping the rollers 9, 10 comprise a rocker 40 actuating through links 41, 44 fingers 42, 45 which engage toothed wheels 38, 39 on the rollers 9, 10 respectively. A magnet 48 in oircuit with the motor 14 attracts an armature 47 on the rocker 40 to release the fingers 42, 45 from the wheels 38, 39 when the motor is running, but when the current is broken allows a spring 51 to turn the rocker 40 and lock the wheels 38, 39. In a modified form of this locking-means the magnet 48 is dispensed with and the rocker 40 is oscillated by a sliding sleeve on the motor shaft controlled by a spring-governor type of device. Slots at intervals in the sheet 13 determine its stoppage positions by operating a switch which breaks the motor circuit. The switch consists of a spring arm 56 making or breaking contact at 57 according to the distance it is pressed by a cam 55 on the back of a pivoted finger 52, which when free to move by the advent of a slot assumes the position shown in full lines in Fig. 3 under the action of a spring 54. The re-starting of the apparatus by a supplementary hand-operated switch tilts the finger 52 in one direction or the other by the pressure of the moving sheet 13 and again makes contact at 57. A thin slotted plate 59 is arranged opposite the finger 52 and in front of the sheet 13. A handoperated switch is also provided for reversing the current through the motor field, thus changing the direction of rotation of the motor and of the rollers 9, 10.

IPC: B60T17/00
Abstract: 132,881. Cox, F. W., and Moore, R. W. Sept. 25, 1918. Fluid-pressure; transmitting-mechanism. -Means for locking fluid-pressure brakes in applied position are controlled by the pressure in the system so that these means are disengaged when the pressure is restored for releasing the brakes. Manual disengaging-means may be provided. A toothed locking-bar 11 connected to one of the levers 7 of the brake mechanism is adapted to engage a detent in the form of a bracket 13 fixed to the car. The bar 11 rests upon the piston 14 of a cylinder 15 communicating by pipe 18 with the usual auxiliary reservoir 4 of the brake system. The pressure in the cylinder 15 is thus normally sufficient to raise the bar 11 out of engagement with the detent 13 against the force of a spring 23, but when, in applying the brakes, this pressure is reduced, the bar falls to the position shown and locks the mechanism in the applied position. The bar 11 is guided by a loop 17 fixed to the cylinder 15. The locking-device may also be released manually by levers engaging beneath the bar 11 and adapted to be actuated by pull-rods extending to either side of the vehicle.

Patent GB-135383-A (GB)
IPC: F41A3/44
Abstract: 135,383. Craig, A. M. Feb. 5, 1919. Machine guns.-Consists (1) in adapting the breech-bolt to be locked in its forward position by the engagement of cushioned rotary members, slidable transversely in the breech-casing, with sockets in the bolt; (2) in adapting these members to be unlocked from the bolt by the recoil of the firing-pin; and (3) of means for controlling the relative movements of the breech-bolt and firing- pin. In the form shown in Fig. 1, the breech-bolt 13 is of square section at its rear end 14, in which are formed sockets 18 designed to receive spring- pressed balls 19, Fig. 5, housed in transverse guideways 19<a> in the breech-casing 15; these balls serve to lock the bolt in its forward position. The firing-pin 27, Fig. 3, has an enlarged portion formed with a conical surface, 34, which serves to force the balls 19 out of their sockets 18 and so unlock the bolt on the initial recoil of the firing- pin after discharge. The firing-pin extends rearwardly through am extension 22 of the bolt, and carries a collar 41 adapted to slide in a member 23, itself adapted to slide in the bolt-extension 22, and forming one abutment of springs 25, 26 which engage respectively at their other ends a shoulder 25<a> on the firing-pin, and the front wall of the extension 22. A pin 39 on the member 23, Fig. 10, is adapted to slide in a slot 36 formed in the bolt-extension 22; while a pin 40 on the firing-pin is adapted to slide in a slot 42 formed in the member 23. The firing-pin is adapted to be locked temporarily to the breech-bolt during part of its movement by the engagement of latches 29, Fig. 7, housed in a slot 28 in the firing-pin, with the sockets 18, the ends of the latches being pressed apart by a spring 31 weaker than the springs 21. When the bolt reaches its forward position under the action of spring 12a, the balls 19 enter the sockets 18, thereby forcing inwards the latches 29 and releasing the firing-pin which is then impelled forwards by the spring 25, and fires the cartridge. Simultaneously the pin 40 strikes a cam 43 in the slot 42, thereby rotating the member 23 and causing the pin 39 on the member 23 to be disengaged from the shoulder 38 in the slot 36; whereafter the springs 25, 26 throw back the firing-pin and the member 23. The firing-pin unlocks the bolt, and itself becomes locked to the bolt as already described, so that the two move rearwardly together. When the member 23 is arrested by the rear cap 12 of the breech-casing, the springs 25, 26 are stressed by the continued rearward movement of the bolt and firing-pin, and the pin 39, moving forward in the slot 36, strikes a cam 37, and is deflected behind the shoulder 38, thus locking the member 23 to the bolt extension 22. The bolt is then moved forwards by the spring 12<a> to the firing position.
