Title: Improvements in or relating to operating mechanism for vehicle brakes
IPC: B61H13/00
Filed: 1920-01-28
Abstract: 138,360. Boirault, L. June 15, 1914, [Convention date]. Actuated or applied by running axle; forcetransmitting mechanism.-Relates to vehicle brakes of the type in which application is effected by the engagement of an eccentric mounted on an axle with a lever which is moved into the path of the eccentric by means of a hand or mechanically operated cam. The invention comprises (1) means for preventing the return of the cam to its inoperative position, (2) means for locking the brakes in the " on " position, and (3) enclosing the mechanism in a casing containing lubricant to maintain a constant coefficient of friction between the parts. The lever 3, which is pivoted on an arm 16 loosely mounted on a shaft 17, is moved into contact with the eccentric 2 by means of a cam 4 loosely mounted on a hub through which an operating shaft 9 passes. The cam 4 is turned in the direction of the arrow, Fig. 2, to apply the brakes by means of a plate 10 keyed on the shaft 9 and connected to the cam 4 by a lost-motion device 11, 12, the cam being prevented from returning by a pair of spring-controlied pawls 20, 21 which are pivoted on the cam and engage a fixed toothed ring 25. The lever 3 is connected by a link 5 to a two-armed lever 6, 7 which is pivoted to the brake rod 8. The brakes are locked in the " on " position by a second loosely mounted cam 26, which may be similar to the cam 4, and also provided with a pair of pawls engaging with the ring 25 in a similar manner to the pawls 20, 21. The cam 26 is connected to the tail of the lever 7 so that it is held in contact with the lever during application and release of the brakes, thereby resisting any tendency of the cam 26 to return suddenly to the " off position. The parts are arranged so that this resistance is at a maximum when the brakes are " off." The connexion consists of a chain 34 passing around the hub of the cam 26 and secured at one end 35 to the cam, the other end of the chain being attached to a spring-controlled red 30 which passes through the eye 29 of a swivelling bolt carried by the tail of the lever 7. To release the brakes, the shaft 9 and plate 10 are turned in the reverse direction, the pawls 20, 21 and the pawls carried by the cam 26 being simultaneously released by the engagement of the edge of the plate 10 with the tails 20<a>, 21<a> of the pawls.
