Abstract
477,333. Fluid - pressure brakes. KERSHAW, A. G., and WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. June 24, 1936, No. 17546. [Class 103 (i)] In a driver's control device for fluid-pressure brakes which is adapted to provide a first stage in which the control is electric and self-lapping and a further stage in which the control is pneumatic, means are provided in which at the beginning of the further stage the electric control mechanism is automatically set to the lap or neutral position so as not to interfere with the pneumatic control. An emergency position of the control handle may be provided in which both the electric and pneumatic controls are effective. The device shown is similar to that described in Specification 467,215, and comprises a floating lever 9 connected by link 7 to an arm 5 on the shaft 2 of the driver's handle, by a link 11 to an arm 13 of a contact lever and to a link 21 slidable in the rod of a piston which is subject to the brake cylinder pressure. The contact lever, pivoted at 15, has an arm 16 carrying a contact 17 adapted to engage fixed contacts 18 connected to application and holding valves. The shaft 2 also carries a rotary slide valve by which the brakes may be applied and released during the further range of movement of the handle independently of the electro-pneumatic control which is effected during the first range of movement. When the handle is in the full electro-pneumatic application position, the contact lever 16 would assume the application position to the left of that shown which is the holding position and in order to return it to this latter position during the pneumatic control range, a cam 51 is mounted on the shaft 2 and engages a roller 52 on an arm 53 provided on the contact lever. When however the handle reaches the emergency position the cam permits return of the contact lever to the application position so that the electropneumatic and pneumatic controls are simultaneously effective to apply the brakes.
