Title: Improvements in and relating to electric traction control systems
Inventor: COLLINS GEORGE
IPC: F16H31/00
Filed: 1957-05-14
Abstract: 828,948. Controllers. BRITISH THOMSON-HOUSTON CO. Ltd. May 7, 1958 [May 14, 1957 (2)], Nos. 15291/57 and 15292/57. Class 38 (3). The cam-shaft CS of a controller is rotated in opposite directions by separate pneumatic engines 1, 2, which are alternately effective, the engine 1 having a sleeve 5 which reciprocates with piston P and carries a pawl 7. During the power-stroke, the pawl 7 engages a tooth in a notched wheel 3, the extension 9 of the pawl leaving a stop 10 so that spring  8 rotates the pawl about its pivot. The piston is returned by a spring SP, the pawl slipping out of the notch. A valve VD controls the flow of gas to space ES so that the gas is admitted when the piston is in its end position, is cut-off at an intermediate point, and is exhausted as the piston approaches the limit of its power-stroke. Pressure gas admitted at inlet IA raises sleeve RS until it engages shoulder SO, the opening CO1 in the sleeve then registering with port IP in the valve-body, whereby gas is supplied through tube CT to the space ES and the piston is moved downwardly. The tube CT is moved with the piston to close opening VO and interrupt the flow of gas to space VS. The shoulder SO of the tube CT engages the sleeve RS which is also moved downwardly, the opening CO1 being moved away from the port IP and the supply of gas to the space ES being interrupted. The gas in space ES now expands and the piston and sleeve are moved further until opening C02 registers with port OP for discharging gas from the space ES. Gas from the space VS escapes through opening BO and outlet OA, so that the valve is re-set while the piston is returned by the spring SP.

Title: Improvements in or relating to rotary engines, pumps, motors, meters, power transmission devices and the like
IPC: F04C2/36
Filed: 1937-06-04
Abstract: 498,226. Rotary engines. BOOTH, M. B. June 4, 1937, No. 15493. [Class 110 (ii)] An engine, pump, or the like, of the rotary abutment type, has axial-displacement means to vary the capacity of the working chamber. Figs. 1, 2, show a rotor Q<4> integral with a shaft Q<1> which is coupled by gears Q<2> to a shaft Q<3> which carries an abutment S<1>. The rotor Q<4> is provided with a flange Q<6> forming one end wall of an annular blade chamber R<2>. A second rotor R<1> carries blades R which pass through slots in the rotor flange Q<6>. A member S forms the outer wall of the working chamber, and carries bearings which support the rotor R<1>. The member S may slide but not rotate. The abutment S<1> has recesses S<2> to accommodate the blades, and engages curved portions R<3>, R<4> of the casing wall and the member S respectively. To balance end thrust on the walls of the working chamber, fluid from the latter is admitted to a chamber S<3> and acts against a piston Q<8> on the shaft Q<1>. When the member S, and the rotor R<1> carrying the blades, are moved to the right, the capacity of the working chamber is reduced. To prevent leakage from the right-hand end of the recess R4 in S, as a recess S<2> passes over it when the engine is operating on reduced capacity, the flange Q<5> is formed on its interior, on each side of the slots in the flange Q<6>, with short curved walls which make a fluid-tight seal with the circumference of the member S while the recess R<4> is brought into communication with either inlet or outlet port. In a modification, Fig. 6, an abutment X has one recess to allow passage of two blades U<2> on a rotor disc U<1>. The working chamber is formed by a casing wall T, and a slidable but non- rotating member W. The blades pass through slots in a disc V<2>. The shaft V<1> is mounted in bearings in the member W, which also carries the abutment member. A piston V4 is under pressure on its left, of fluid from the working chamber. To reduce the capacity of the latter, the shaft V<1> and member W are moved to the left.

Abstract: 542,566. Planing. DENNY & BROS., Ltd., W., and BARBACK, B. Nov. 8, 1940, No. 16272. [Class 83 (iii)] A planing or like machine has the feed actuated from a driving shaft 1 rotated alternately in opposite directions by the drive to the reciprocating work-table or tool through a clutch having a movable member 5 which is engaged by mechanism controlling the extent and timing of the feed and disengaged by a roller 41 or like stop which is moved by said mechanism into the path of a part 9 of the movable member. The driven shaft 2 carrying the movable clutch part is connected to the feed through reduction gear not shown, feed steps corresponding to one or more revolutions of the shaft 2 being obtainable. A toothed ring 13, driven through gearing 26, 27 through less than one revolution for the maximum table or tool travel, is adjustably secured by a latch 28 to a member 16 keyed to a sleeve 17 carrying an arm 18 and loose on a shaft 19. The latter carries an intermediate arm 23 counterweighted at 23a and a clutch-operating two-armed lever 24 counterweighted at 24a. The arms 23, 24 are connected by a spring ball 25 so that they move together until the arm 24 is arrested. The spindle 19 is connected by arm 29 and latch 30 to a quadrant 31 on the disc 15 and the ring 13 and quadrant preferably rotate through one tooth pitch for each rotation of the shaft 1. A lever 33 pivoted at 32 has one arm movable between stops 42, 43 and the other has teeth 37 operating a spindle 39 carrying an eccentric roller 41 operating the clutch. The arm 33 is operated against a spring 36 by the engagement of arm 24 with a trigger 34 which may be moved out of the path of the arm by a handle 44 if feed is not required. In operation, during the stroke in which feed is to be effected the ring 13 drives the disc 15 and thus the arm 18. Through the latch 30 the shaft 19 is also driven thus rotating the arms 23, 24, until the latter actuates the lever 33 and roller 41 to move the clutch part 5 into engaged position and start the feed. The arm 24 is arrested but the arms 18 and 23 continue their movement until the arm 18 lifts the trigger 34 clear of arm 24 which is then moved by weight 24a to its former position relative to arm 23 and re-engages the ball connection 25. The part 33 is then returned by spring 36 thus placing roller 41 in a position, Fig. 5, where it coacts with projection 9 to disengage the clutch and stop the feed. In the reverse direction the arm 18 lifts the trigger 34 and the member 33 is not actuated. The duration of the feed is determined by the angular relation of arms 24 and 18 and is adjusted by the latch 30 and quadrant 31. The timing of the feed is determined by relative adjustment of the discs 13, 15 by means of the latch 28.
