Title: Improvements in and relating to variable length motion transmitting devices
IPC: F01L1/20
Filed: 1943-03-15
Abstract: 567,711. Linkwork. WESTLEY, C. (Boots Aircraft Nut Corporation). March 15, 1943, No. 4210. [Class 80 (iii)] [Also in Groups XXV and XXVII] Consists in means for effecting and maintaining an adjustment of the length of a link which comprises inter-engaging screwthreaded members. As applied to a tappet for an overhead valve of an internal-combustion engine, a rocker arm 1, Fig. 1, engages at one end the valve stem 3, the other end having a boss 5 threaded to receive a rod 6 a ball 6a on which enters a cup 7a on the valve rod 7. Adjustment, to obtain the correct clearance between rocker arm and valve stem, is effected by rotating the rod 6 which is preloaded to obtain a frictional grip between the threads of the rod and the boss 5. This is effected by a spring washer 8, Fig. 2, which is sinusoidal and includes two pairs of oppositely extending axially spaced projections 8a, 8b. The projections 8a are received in a slot 9 in the boss 6, the projections 8b co-operating with arcuate slots 10a in the face of a nut 10 threaded on the rod 6, the nut requiring a wrench of unusual shape to rotate it to adjust the preloading. Adjustment of clearance is effected by merely rotating the rod 6 with a screw-driver. As applied to the valve of an L-head engine, Fig. 6, the cam 16 acts upon a part 15 into which is forced a preloading device 18 comprising threaded portions 18b, 18d connected by a resilient portion 18c. Before the threaded rod 14 is inserted, the two threaded portions 18b, 18d are put out of phase, as regards the threads, by end pressure, so that when rod 14 is screwed in, the phase is restored with a consequent axial force on the rod. Reference has been directed by the Comptroller to Specifications 243,401, [Class 80 (iii)], and 549,434, [Group XXV].

Patent GB-247603-A (GB)
Title: Improvements in rebound checks for vehicles
IPC: F16F7/02
Filed: 1926-02-15
Abstract: 247,603. Hassler, R. H. Feb. 14, 1925, [Convention date]. Vibration-dampers.-In a one-way or rebound damper for vehicles one of two annular conical friction elements is fixed to the frame and the other is oscillated in one direction by a connection to the axle and in the other by a spring. One element 14 is of wood and is fixed to a base 10 secured to the vehicle frame 11. The co-operating metal element 20 is riveted to discs the outer parts of which are extended to form a drum 24, 25. The drum is rotated in one direction by a strap 28, one end of the strap being fixed to the drum and the other to the axle. Rotation of the drum in the other direction is effected by a spiral spring 32. The outer end of the spring engages a pin 35 on the drum and the inner end is bent to engage one of several grooves in an extension 10g of the base. When the spring is free, the inner convolutions project to one side, as shown in Fig. 10, so that when flattened by the ball 40, the spring presses the friction element 20 inwards into engagement with the element 14. This pressure is exerted through a disc 46 and conical. wooden block 44 which is clear of the base 11 so that the conical element is free to centre the drum. In a modification, the block 44 bears on the extension 10g of the base 10 so as to centre the drum independently of the conical friction elements.

Title: Improvements in machines for hammering piston rings
IPC: B23P9/04
Filed: 1922-02-16
Abstract: 195,826. Wells, E. L., and Light Production Co., Ltd. Feb. 16, 1922. Planishing and beating.-A machine for distributing blows, at varying distances apart, on the inner face of a piston-ring has automatic means for varying the angle through which the ring carrier C is rotated between the blows and for stopping the blows and the rotation at desired angular positions of the carrier so that the ring is not hammered adjacent to the slit. The ring is placed against a shoulder in a ring of the required size arranged in the carrier and held there by radiallyadjustable spring plungers Z, Z on a door V. A spring-pin 5 is then pulled to withdraw it from the tail of a spring pawl 3. Fig. 3, mounted on a shaft K and allow it to engage teeth 1 ot a driven pulley 2, thereby rotating the shaft with its hammeroperating cam 17 and a crank-pin P for oscillating a friction ratchet Q, Fig. 1, which rotates the carrier. The eccentricity of the pin P and hence the feed of the carrier is varied by an incline M, Fig. 3, on a, spring-pressed rod J which is moved axially bv a lever H, rod F and a cam D on the carrier. When the pin 5 is pulled out it moves the cam 17 axially, into its operative position, by means of a notch 12, Fig. 4, spring pawl 13, fork 15 and groove 16 and it is locked by a detent 10. When sufficient of the ring has been hammered an adjustable projection 22 on the carrier strikes the pawl 13 which is released from the notch 12 and a spring 18 moves it and the cam 17 to bring a concentric surface 20, Fig. 3, below the hammer bowl 19, then, when the slit in the ring has passed below the now stationary hammer 23 a second projection 11 strikes the detent 10 and releases the pin 5 which is pulled in by a spring 7 and engages the pawls 13, 3, the latter stopping the drive. A brake T<1> prevents retrograde movement.

Title: Device for change-over of variable drives
IPC: F16H3/14
Filed: 1957-02-11
Abstract: 852,629. Change-speed control. VOITH G.m.b.H., J. M. Feb. 11, 1957 [Feb. 9, 1956], No. 4666/57. Class 80 (2). At least one shaft, e.g. the input shaft 10, of a change-speed and/or reverse gear on a rail vehicle, controlled by dog-clutches, e.g. 42, is provided with a rotation-detecting feeler 11, 12, which permits a change to occur only when the shaft 10 is stationary, additional means being provided for moving the feeler out of contact with the shaft when the latter is rotating, thereby preventing unnecessary wear on the feeler. In the reverse gear shown, freely mounted wheels 44, 45, which can be clutched to the input shaft 10 by the dog clutch 42, mesh wheels 70, 72 (the latter through an idler) fast on an output shaft, not shown. A selector lever 1. operates valves 2, 7 permitting compressed air to flow from a supply 4 to pipe lines 6 or 8. With the selector lever in the forward position V as shown, compressed air is directed via the pipe 6 to the cylinder space 9 of the feeler 11, and to the normally closed control valve 18. If the shaft 10 is rotating, the feeler 11 is deflected thereby, and a piston 14 allowed to travel to its upper posi. tion which uncovers a port 15 allowing the compressed air to flow through pipes 161, 47 to a chamber 35 at the left of a selector locking piston 32. The space at the right of the piston 32 has meantime become filled with compressed air via passages 16, 21, 30 and balances the force exerted on the piston which remains in the locked position by virtue of the spacing 33. If however the shaft 10 is stationary, the feeler 11 is not deflected and the piston 14 does not move sufficiently to uncover the port 15. The pressure build up on the right hand side of the piston 32 moves the piston and locking rod 34 to the left, disengaging notches 48 and opening valves 19, 25. The compressed air is allowed to flow through the duct 17 to a pipe 39 to operate a piston 37 which engages the forward gear train. Rotation of the shaft 10 will then deflect the feeler 11 to lock the selector piston in its newly engaged position. For reverse drive a second feeler device 28, 12 and valves 7, are provided for similar operation. Non return valves 22, 50 prevent the passage of compressed air from the forward to the reverse system and vice versa. A single feeler and piston common to all paths and controlled by non-return valves may be used. The additional means for moving the feeler out of contact with the shaft 10 when the latter is rotating is shown in Fig. 3, which is an enlarged detail view of one feeler 112 and its shaft 110. Such means comprises a pin 159 on the feeler 112, which pin, when the feeler 112 is deflected by contact with the rotating shaft 110, eventually rides over one or other end of a gap in a fixed sleeve 158 surrounding the shaft, to lift the feeler 112 clear of the shaft at the limit of its deflection.
