Filed: 1928-02-13
Abstract: 303,054. Servo-Frein Dewandre Soc. Anon. Dec. 27, 1927, [Convention date]. Fluid-pressure.-In fluid-pressure brakes on a towed vehicle automatically controlled by the displacements relative to the towing vehicle of the towed vehicle, owing to its inertia, the rod of a coupling member provided upon the towing or the towed vehicle, taking part in the relative displacements of the vehicles controls a member connected to a distributor provided upon the towing vehicle in order to control the action of a fluid upon an auxiliary motor or motors on the towed vehicle to apply the brakes. For movement in reverse the operation of the member controlling the braking fluid may be reversed so that the towed vehicle is braked on moving away from the towing vehicle. The towing vehicle 23 is coupled to the towed vehicle by a member 6 having a sliding movement in a guide 7 limited by stops 20, 21. On the towed vehicle overtaking the vehicle 23 when the latter slows the member 6 is moved and by means of a lever 8, a rod 18, a lever 10 and a rod 13 operates the distributor 1 to connect the brakes cylinders of the towed vehicle to suction by means of pipes 3, 5. The rod 13 is connected to the lever 10 by means of a slider 12 adapted to be moved in a slot in the lever 10 by connections 15 to a hand lever operated by the driver so that the slider may be moved to the other end of the lever 10 to obtain a reversal of the operation of the mechanism when the vehicle is reversed. In a modification the part of the coupling connected to the towed vehicle is formed as a sleeve sliding over the member 6 and adapted to bear upon and to operate directly the lever 8 which is returned by a spring. A pin is arranged to be passed through holes in the sleeve and the member 6 to prevent operation on reverse movement of the vehicles. The pin may be operated by control from a distance by the driver.
