[Class 103 (i)] In electrically-controlled vacuum-operated brake apparatus wherein the maximum available brake application is varied in consonance with the speed, an electromagnetic release valve 16, Fig. 2, is provided in the vacuum system and has two operative conditions in one of which it is responsive to normal vacuum and opens on such vacuum being exceeded and in the other condition the valve is held closed. As shown, the apparatus comprises a speed indicator 3 having a movable contact 12, a reservoir vacuum pipe 7 with vacuum governors 8, 9 operable above a 16 inch and 25 inch vacuum respectively to break contacts 10, 11 in the circuit of a supplementary exhauster 6 for producing the increased vacuum, and electromagnetic switches 4, 5 energized according to the speed of the train by the closing of contacts 12, 13 or 12, 15 respectively. During normal running contacts 12, 13 are closed and solenoid 4 closes contacts 24 in exhauster circuit. If the vacuum is below 16 inch, contacts 10 are also closed and the exhauster circuit completed to increase the vacuum to 16 inch. When the speed of the train increases, contacts 12 and 15 close and energize solenoid 5 to close contacts 25. Contacts 11 of the governor 9 are also closed so that the exhauster circuit is completed and the exhauster operated to produce a 25 inch vacuum. When the speed falls the contacts 12, 15 open to operate the relief valve 16, Fig. 2, to release the vacuum to 16 inch. The valve 16 is placed between the train pipe 17 and atmosphere 18 and is held on its seating by a spring 20 set for a 16 inch vacuum. When the contacts 12, 15 close to operate the exhauster to produce a 25 inch vacuum, the solenoid 22 is energized and the valve maintained close. When the speed of the train falls, the solenoid is de-energized and the valve opens until the vacuum falls to 16 inch when it is closed by the spring 20. A switch 26 may be opened when the train is accelerating or cuts out the high speed circuit when the train is running empty. The Provisional Specification states that the apparatus may be modified to suit it to compressed air brakes.
