Filed: 1973-05-11
Abstract: 1460280 Brake systems; service cylinders CLAYTON DEWANDRE CO Ltd 6 May 1974 [11 May 1973] 22535/73 Heading F2F A brake actuating mechanism comprises a cylindrical housing 1 containing a piston structure 2 defining a spring chamber 27 and a compressed air chamber 10, and a separate hydraulic service cylinder unit 11 clamped or bolted to the housing 1, a plunger 20 providing a thrusttransmitting connection between a bolt 23 threaded to a nut 22 secured to the piston structure 1 and a piston 21 of the hydraulic cylinder unit 11 the bolt 23 being rotatable after a spring application of the brake for effecting release of the brake. In the embodiment of Figs. 1, 2 the unit 11 has a radial mounting flange 12 which is held fast against a ring structure 8 of the housing 1 by a two-part clamping ring 13. A hollow axial extension 14 projects into the housing 1 and into sliding engagement with a tubular axial extension 5 of the piston structure 2. The extension 5 extends within a hub portion 6 of a detachable end plate 3, and the nut 22 is secured to the enlarged free end of the extension 5. The plunger 20 is located within the extension 14 and one end of the plunger 20 is formed integral with or has operative connection with the piston 21. A breather drain 26 arranged at the lower side of the installed assembly communicates with the spring chamber 27 via slots 28 in the peripheral rim of the end plate 3. Normally compressed air in chamber 10 holds the piston structure 2 in the retracted position whilst a predetermined fall in the air pressure permits the piston structure 2 to move towards the unit 11, this movement being transmitted through the nut and bolt gear 22, 23 and the plunger 20 to the piston 21 to apply the brake. To release the brake while a supply of compressed air is not available, the head 24 of bolt 23 is rotated after removal of a dust cover 25 to permit the piston 21 to retract under the action of the brake pull-off springs. In the modification of Fig. 3 the hydraulic cylinder unit has an annular flange 30 bolted directly to an annular end wall 29 integral with housing 1. The end wall 29 is formed with an integral sleeve portion 32 upon which piston structure 2 slides.

Filed: 1963-06-07
Abstract: 970,802. Vehicle parking brakes. ATWOOD VACUUM MACHINE CO. June 7, 1963, No. 22729/63. Heading F2E. A vehicle parking brake operating mechanism comprises an operating pedal 10 pivoted on which is mounted an arcuate member 16 substantially concentric with the pivotal axis 11 of the pedal, the latter being adapted to apply the parking brake of a vehicle through a pair of cables 14, frictional locking means 21-25 inclusive are provided to hold the operating pedal in the " brake applied" position, manually controlled means 20 being provided to disengage the locking means to release the pedal. The mechanism is shown in its fully released position with the end of the arcuate member or quadrant 16 pivoted to the pedal 10 on a rivet 15 abutting a rubber bumper 17. When the pedal 10 is moved in a clockwise position about its pivot to apply the brake, the pedal also pivots the quadrant 16 such that the latter moves between a hollow roller 22 and a roller 23 with a combined rolling and sliding action, the roller 23 being held against the inner surface of the quadrant by the force of a spring 26. When the pedal has reached a position corresponding to the fullyengaged brake position, it is released and the reaction of the braking force acts through the cables 14 towards the pedal in an anti-clockwise direction. The frictional forces between the roller 23 and the quadrant 16 and between the roller and the insert 25 cause the roller 23 to become wedged firmly between these two members and the quadrant, in turn, is wedged between the roller 23 and the roller 22. The brake is thus held in its fully applied position. In order to disengage the locking means, the hand lever 20 is moved in a counter-clockwise direction about its pivot to withdraw the roller 23 from its wedging engagement between the insert and the quadrant and the quadrant is now freed so that the pedal will be returned to the position shown in Fig. 1 under the force acting in the cables 14.
