Title: Improvements relating to driver's brake control devices for fluid pressure braking apparatus
Inventor: HIGGINS HORATIO LESLIE
IPC: B60T15/04
Filed: 1958-07-10
Abstract: 875,392. Fluid pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. July 10, 1959 [July 10, 1958], No. 22158/58. Class 103 (1). In a driver's brake control device for use with fluid-pressure operated braking apparatus controlled electrically, a manually operable switch means is provided as part of the device for isolating the latter electrically and is so interlocked with the handle of the device as to be operable only when the handle is in a shut-down position. In the driver's brake control device shown in Fig. 4 cam plates 11 and 12 are in fixed coaxial relationship with a spindle 13 of the handle 13a of the device so that they rotate with the handle 13a. Disposed on an axis parallel to the axis of the handle spindle 13 is a key spindle 14 rotatable between three 120-degree positions shown in Fig. 1 by means of a removable key 14a. When the key spindle 14 is in position A (Figs. 1, 2A, 3A) and the handle is in the shut-down position and it is required to make the brake control device operative, the key 14a is inserted and is first of all turned to position B. It cannot be turned further at this stage because in the shut-down position a cam plate 11 obstructs a rocker 25 and contacts 19, 20 of an isolating switch are therefore closed. The handle is then moved to the emergency position when it becomes possible to turn the key to position C and so enable the handle to be moved in the operative range of positions. When shutting down, the sequence of events is reversed and the brake controlling circuits are broken by the movement of the handle from the emergency to the shut-down positions before the key can be returned to position A to break the contacts 19 and 20. The contacts may be so connected as to complete the circuit of an indicator lamp (not shown) when closed. A cut-out portion 28 in the cam plate 11 permits movement of the handle from the shut-down to emergency positions with the key spindle remaining in position A so that the brake pipe may be vented in an emergency without the need of a key.
