Title: Improvements in brake mechanism for vehicles
IPC: B60T13/58
Filed: 1929-06-07
Abstract: 334,880. Bosch Akt.-Ges., R. Dec. 3, 1928, [Convention date]. Addition to 318,484. Fluid-pressure.-Manually actuated mechanical releasing means for vehicle brakes that are applied by a spring or other energy storing device and normally released by fluid-pressure or vacuum and in which the manual means is put out of action by the movement of the brake piston when the fluid pressure or vacuum is established as described in the parent Specification comprises in one construction, a hand-lever 10 connected by a cable 9 to the brake shaft 6 to which also the piston 3 is coupled. By turning the lever 10 until it abuts against the stop 12, the brake is released against the action of the application spring 4, and the lever having passed the dead-centre position is held in the release position by the tension in the cable due to the spring. When vacuum is established in the cylinder 2, the further inward movement of the piston 3 relaxes the tension in the cable 9 and permits the lever 10 to be returned to the inoperative position B by a spiral spring 13. In another construction, Fig. 2, the cable 9 is connected to a lever 21 pivoted upon a bearing 22 slidable upon but not in screw-threaded engagement with a screw 14. To release the brake the screw 14 is rotated by the crank 17 to traverse a nut 18 to the right to permit the engagement therewith of a projection 20 on the lever 21 as shown. The rotation of the screw is then reversed to move the nut 18, lever 21 and cable 9 to the left thus releasing the brakes. When by establishing the vacuum in the cylinder 2 the cable 9 is relaxed the lever 21 is disengaged from the nut 18 by a spring 23 thus rendering the manual release device inoperative. In a modification of this construction the bearing for the lever 21 is not arranged on the screw 14 and as soon as the lever is disengaged by a compression spring the bearing and lever are returned by a spring.

Arrangements of springs with mountings complete in themselves.-In spring suspension apparatus for motor and other vehicles, oppositely disposed springs are adapted to bear on a cam shaped member displaceable against the action of a suspension spring, the oppositely disposed springs being arranged to resist the return of the parts to the normal position. As shown, the suspension comprises a two-armed lever A pivoted at B to the chassis and carrying the axle at the end of its longer arm, while its shorter arm is acted upon at a variable distance from the pivot B by a spring D. The spring D, which is enclosed in a casing J pivoted at E to the chassis, acts through a rod F which carries a roller C bearing on the shorter arm of the axle-carrying lever A. The rod F also carries a cam G which works between spring-pressed rollers H, I and is so formed that normal movements of the wheel axle away from its position of equilibrium are accelerated, while the return movements are retarded. The ends of the cam are formed so that abnormal movements of the axle are resisted. The oppositely disposed springs and cam device may be arranged to act directly between the axle and chassis as shown in Fig. 2. The Specification, as open to inspection under Sect. 91 (3) (a), describes also the use of laminated springs for controlling the rollers H, I. This subject-matter does not appear in the Specification as accepted.
