摘要： 295,454. Winter, H. J., and Westing- house Brake & Saxby Signal Co., Ltd. May 21, 1927. Fluid-pressure.-Fluid-pressure braking apparatus of the combined compressed air and vacuum type comprises a valve for automatically comtrolling the release of fluid under pressure from the compressed air brake pipe under the combined influence of the automatic compressed air brake pipe pressure, the vacuum brake pipe pressure and a constant pressure, in order that an application of the vacuum brake causes a corresponding reduction of the compressed air pipe pressure. An energizing valve may also be provided to release pressure from the compressed air pipe in an emergency application of the vacuum brakes. A diaphragm 2 separates the valve casing into two compartments, a compartment 3 open to the atmosphere through an aperture 5 and a compartment 4 connected to the vacuum brake pipe. A spring 6 presses on the under side of the diaphragm. The diaphragm is provided with a stem 8 the upper part of which is secured to a diaphragm 11 separating chambers 12, 13. The chamber 12 communicates with the atmosphere through an opening 14 and the chamber 13 communicates through a restricted port 17 with the upper side at the piston 18 of the equalizing discharge valve and also through a non-return valve 15 with the compressed air brake pipe 16 which permits recharging thereof. The upper end of the stem 8 is tubular, opening into the chamber 12 by an aperture 21 and carrying in its upper end a valve 22 connected to a spring closed valve 24 controlling communication of the chamber 13 with a passage 26 leading to a feed valve. The pressure of the spring 6 and the atmospheric pressure in chamber 3 in equilibrium with the pressure fluid supplied from the feed valve through the passage 26 maintains the valve closed and the valve 24 open. On admission of air to the vacuum pipe 7 the diaphragms move downwards closing the valve 24, thus cutting off communication between the feed valve and the compressed air pipe 16 and the stem 8 then moves away from the valve 22 opening communication between the atmospheric chamber 12 and the upper side of the piston 18 which moves to vent the compressed air brake pipe 16 through a port 29 and apply the compressed air brakes. When the compressed air brake pipe pressure has been reduced to a predetermined extent the .diaphragms rise again to reclose the valve 22 owing to the reduction of pressure in the chamber 13 and the release of fluid by the piston 18 is interrupted, as pressure acting on the under side of the piston 18 through an aperture 28 is also reduced. During release of the brakes the converse action of the ports takes place. The spring 6 can be adjusted so that the closing movement of the piston 18 takes place at any desired degree of reduction of the compressed air pipe. The emergency valve comprises a reservoir 30 closed by a diaphragm 31 and maintained at the pressure obtaining in the vacuum pipe 7 by a small aperture 33 in the stem 32 of the diaphragm. On complete destruction of the vacuum in the pipe 7 the diaphragm rises and opens the compressed air brake pipe 16 to atmosphere by raising a valve 40 by means of a lever 37 connected to the stem 32. The connection to the pipe 7 is made adjacent the driver's brake valve to render the action of the valve sensitive.

摘要： 205,356. Winter, H. J., and Westing- house Brake & Saxby Signal Co., Ltd. Oct. 31, 1922. Fluid-pressure.-In a straight air brake wherein a valve automatically connects the operative driver's valve to the brake cylinder when the brakes are to be applied, a conductor's brake valve by which an independent application may be effected is provided, and is so constructed that the brakes so applied may be released by the driver from the opposite end of the vehicle by suitable manipulation of his valve, whether the conductor's valve be closed or open. In the form shown, a driver's valve 1 is provided at each end of the vehicle, and communication with the brake cylinder 3 is controlled by a double-check valve 5, which comprises a piston chamber 8 in which a piston 9 works, and valve chambers 10, 11, each containing a slide valve 12 operated by a stem 13 on the piston to control exhaust ports 14. When the right-hand driver's valve is operative and is moved to application position, the piston 9 is moved to the left, the brake cylinder is charged from the chamber 11 and the chamber 10 exhausts through its port 14. Similarly, when the lefthand valve is operative, the chamber 10 charges the brake cylinder, and the chamber 11 is vented. The conductor's brake valve 7, which comprises a cock 16 and a pressure-limiting valve 19 controlled by a spring 20, by-passes the driver's valve. When the cock 16 is opened, fluid passes from the reservoir 4 to the pipe 6 and the piston 9 is moved to the right, but the pressure with which the brakes are applied is lower than main reservoir pressure, because of the reducing action of the valve 7. To release the brakes at the opposite end of the vehicle the driver first moves his valve to application position, when fluid at main reservoir pressure entering the chamber 11 overcomes the lower pressure in the chamber 10 and moves the piston 9 to the left, thus venting the chamber 10. By moving his valve to release position the driver may now release the brakes, as the piston 9 will remain in its left position.

摘要： 218,706. Peter, B. H., Winter, H. J., and Westinghouse Brake & Saxby Signal Co., Ltd. March 10, 1923. Fluid-pressure brakes controlled either electrically or by variations in train pipe pressure. The complete release of the brakes by electric means is prevented by interposing a loaded check valve in the passage leading from the brake cylinder to atmosphere. The braking system shown in Fig. 1 comprises a driver's valve 3, triple valve 1, auxiliary reservoir, and brake cylinder 2, and an electrically-controlled release valve 7 controlling the exhaust from the brake cylinder through the pipe 29 to an exhaust port 25. When the valve winding 9, Fig. 2, is energized, the rod 20 is raised to open the exhaust valve 20 against its spring 22, but when the brake cylinder pressure has fallen to a predetermined value, the check valve 26 closes under the aotion of the spring 27 to prevent further release, complete release being effected pneumatically. The winding 9 is energized by tilting the handle 19 of the driver's valve to close the contacts 18 by means of the pivoted arm 30, this action being permitted only when the handle is in the " lap " position.

摘要： 344,058. Fluid-pressure brakes. WINTER, H. J. and WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London. Dec. 2, 1929, No. 36933. [Class 103 (i).] Fluid-pressure brakes for vehicles such as trolley buses in which the brake pedal adapted to be depressed by the driver in order to apply the brakes when required, has associated therewith arrangements whereby the brakes are applied automatically in event of the driver failing to maintain his foot upon the brake pedal or a member associated therewith. The vehicle power unit is cut out when the brakes are being applied. The brake cylinders 1 are supplied in normal brake application from a reservoir 4 by means of a control valve 2 operated by a pedal 3 through a double-check valve 20. The reservoir 4 supplies fluid to a chamber 14 in an emergency valve 12 and through a restricted passage 22 to a chamber 16 above a piston valve 13 so that a spring 23 maintains the valve on its seat. A pilot valve 8 in the brake pedal is maintained on its seat by a spring 10 and a stem 9 by the presure of the driver's foot. If this is released, fluid in the chamber 16 is released through a flexible connection 17, the valve 8 and an atmospheric port 11 and the piston 13 is raised by the fluid pressure in the reservoir 4 and fluid is admitted to a chamber 18. When the pressure in this chamber has attained a certain value a spring-pressed valve 24 is raised to admit fluid to the check valve 20 a valve element 21 in which is moved to the right to admit fluid to the brake cylinders 1. The valve 24 is provided to ensure that the degree of application by the pilot valve is less than that which can be obtained by the valve 2, so that the check valve 20 can be reversed by fluid from the valve 2, and the brakes released through the valve 2 when the foot-pedal is first depressed, then released. When the pedal is depressed the valve 8 is reseated and pressure allowed to build up in the chamber 16 and the piston valve 13 reseated and the reservoir 4 cut off from the check valve 20. The electric control circuit of the vehicle motor may be cut off by a pneumatically-operated device 25 associated with the check valve 20 and comprising a spring-pressed piston 26 operating a contact member 27 in the control circuit 29. A cut-out cock 30 is provided between the reservoir 4 and the emergency valve 12 to prevent loss of fluid through the parts 22, 11 and this cock also breaks the circuit 29 in order that the vehicle may not proceed with the reservoir and emergency valve 12 disconnected.

摘要： 314,828. Winter, H. J., and Westing- house Brake & Saxby Signal Co., Ltd. March 30, 1928. Fluid-pressure.-In a control device for fluidpressure or vacuum brakes applied to aircraft, port or starboard brakes may be applied simultaneously or independently by a single controlling lever. As shown, a lever 16 is articulated to a rotary valve 4 which is capable of putting one or both brake chambers 10 and 11 into circuit with a chamber 2. The lever is also capable of operating one or other of two valves 23, 22 so as respectively to put the chamber 2 into circuit with the pressure cylinder 28 or to vent it to the atmosphere. The valve 4 has a conduit 12 with side branches as shown in Fig. 2, so that by a slight rotation of the lever 16 in one direction the valve will cut off connection to one of the brake chambers while maintaining the other connection. A similar movement in the other direction reverses the process. In the mean position circuit is established to both chambers. The valves 23, 22 are spring pressed and are released from their seats by an oscillatory movement of the control lever and the consequent engagement of a projection 17 in the control lever with one or other of corresponding plungers 19, 18.

摘要： 310,912. Winter, H. J., and Westinghouse Brake & Saxby Signal Co., Ltd. Feb. 2, 1928. Fluid-pressure. - Fluid-pressure braking apparatus of the combined automatic and straight type comprising light and load brake cylinders is provided with a valve device adapted under load conditions, both in automatic and Straight application, to control the supply of fluid under pressure to the brake cylinders so that the stroke of the light cylinder is rapidly effected and substantially completed before fluid is supplied to the load cylinder, and when the brakes are released the venting of fluid from the load cylinder is completed first. In automatic application the fluid supplied from the triple valve 28 moves a check valve 26 in the valve device to close the straight air pipe 29 and passes through ports 31 to a chamber 15 and passages 16, recess 18 in a piston valve 4, passages 21, 22 to the light cylinder 20, also through a restricted passage 24 to this cylinder, and the slack in the brake rigging is taken up and a braking effort applied. When the pressure in the cylinder 20 and chamber 15 has obtained a predetermined value the piston 4 is raised against the pressure of a spring 8 closing the communication of the load cylinder 14 with the atmosphere through a port 6 and supplying it with fluid under pressure by a restricted port 23. Communication between the chamber 15 and the cylinder 20 through the recess 18 is out off by the upward movement of the piston 4, but the supply continues through the port 24. Fluid is released from the brake cylinders through ports 23, 24 and the triple valve until a predetermined reduction in the pressure in the cylinder 14, when the piston 4 returns to the lower position and the cylinder 4 is vented direct to the atmosphere through a port 6 and the cylinder 20 is vented through the recess 18, but not so rapidly as the cylinder 14, so that the venting of this latter is completed first. When straight air is supplied through pipe 30, 29 the check valve 26 is moved to close the pipe 27 from the triple valve and the supply and release of fluid to and from the brake cylinders takes place through the same passages as in the automatic application. The brake cylinder 14 may be rendered inoperative when the vehicle is empty by means of a cock 37 which connects it to the atmosphere.

摘要： 268,036. Winter, H. J., Leech, K. H., and Westinghouse Brake & Saxby Signal Co., Ltd. Dec. 24, 1925. Multiple-way valves. -In a valve for the flexible hose coupling between adjacent railway vehicles, the operating spindle 17 of the main valve 9 has a flat bleed valve disc 12 serving as a fluid tight joint for the spindle 17 and permitting escape of steam or other fluid from one side of the main valve 9 when the latter is closed. As shown, the bleed valve seat 15 has an opening 20 leading at 21 to one side of the main valve 9 and communicating when the latter is closed by a passage 22, or a groove in the valve disc 12, with a passage 23 in the spindle 17 leading to the atmosphere at 24. The disc 12 is pressed to its seat by a spring 14. When the spindle 17 is turned to open the main valve communication between the passage 20 and the atmosphere is interrupted. The spindle 17 may be separate from but rotatably secured to the disc 12, the valve seat 15 having two ports, one leading to one side of the main valve 9 and the other to the atmosphere, communication between the two ports, when the main valve 9 is closed, being established by a semicircular or other groove in the face of the disc 12.

摘要： 301,358. Winter, H. J., and Westing- house Brake & Saxby Signal Co., Ltd. Aug. 27, 1927. Fluid-pressure.-Application of the vacuum brakes on a locomotive is brought about by the application of the compressed air brakes on the train by means of a control valve comprising a valve 19 adapted to admit air to the vacuum train pipe 7 and controlled by the pressure in the compressed air train pipe acting in a chamber 14 on a piston 18, and the pressure in the vacuum train pipe acting in a chamber 3 on a diaphragm 2 and a substantially constant pressure acting in a chamber 10 on a piston 9. The pistons 9, 18 and the valve 19 are attached to the diaphragm by spindles 9 , 21. The constant pressure is supplied to the chamber 10 through a non-return valve 12 and the chamber 14, from a pipe 15 connected to the equalizing reservoir 16 of the compressed air drivers valve. Atmospheric pressure exists in chambers 4, 20. When the pressure in the compressed air train pipe is reduced the pressure in chamber 14 is reduced and the pistons and diaphragms move to the left to open the valve 19 and admit air to the vacuum pipe 7 through the chamber 3 and pipes 5, 24, until the pressure in the chamber 3 is sufficient to move the diaphragm to reclose the valve 19. For every pressure in the compressed air pipe there is thus a corresponding pressure in the vacuum pipe. A modified arrangement is shown in which the constant pressure in the chamber 10 is replaced by a spring acting on the diaphragm 2. The spring and the constant pressure may be used simultaneously. A cock 6 is provided so that the control valve can be cut off from the vacuum pipe 7 when the locomotive is coupled to vehicles having vacuum braking apparatus. When the control valve is connected to the train pipe 7 a small passage 26 in the cock leads to the ejector device 28.

摘要： 237,102. Winter, H. J., and Westinghouse Brake & Saxby Signal Co., Ltd. July 31, 1924. Fluid-pressure. - A trip valve, adapted when actuated by means on the track, to vent the train pipe to apply the brakes, is reset by means of fluid pressure, either by means under the control of the driver, or automatically, when a predetermined pressure reduction has been effected or after a predetermined time. In the form shown, in Fig. 2, the trip valve 2, controlling communication between the train pipe 3 and the atmosphere at 4 through a second valve 5, is adapted to be reset by the stem 11 of a valve 7, subject to main reservoir pressure in a chamber 8, and to train pipe pressure through a port 3 and to the pressure of a control spring 9, when the train pipe pressure has been reduced by a predetermined amount. In order that the descent of the valve 7 may be rapid, a portion only of its upper face is subject to main reservoir pressure when it is closed. After the valve 2 has been reset, the valve 7 is raised to its normal position on restoring the pressure in the train pipe. In the form shown in Figs. 3 and 4, in which the valve 2 is reset after a predetermined time, the train pipe 3 is connected to a timing-reservoir 16 through a check valve 18, a casing 24 between the parts 16, 18 being provided with a pair of valves 25, 26, subject on their outer faces respectively to main reservoir pressure, and to the pressure in the reservoir 16, and having between them a spring 27. When the train pipe and reservoir are charged, the valve 25 is held in the raised position shown, in which it cuts off the main reservoir from the chamber 8 above the valve 7, Fig. 2, through the pipe 17 and connects the latter to atmosphere at 28. When, however, train pipe pressure is reduced by the operation of the valve 2, the pressure in the reservoir 16 falls by escape of air to the train pipe through an adjustable small port 20 in the valve 18, so that after a predetermined time the valve 25 is opened to supply pressure to the chamber 8 to actuate the resetting valve 7, the valve. 26 moving to its seat 29 to prevent leakage therethrough. In a further form shown in Fig. 5, a manually operable valve 30 may, in the position shown, connect the chamber 8 to atmosphere, either past the valve stem 32 or through a small port, and be adapted, when moved to the left, to open a valve 31 to supply air at main reservoir pressure to the chamber 8, a packing 33 then serving to prevent leakage past the stem 32. In further forms, an electromagnetically operated valve may be used, or an additional fluid-pressure line may be provided, the supply to which is controlled by the driver. Isolating cocks may be provided to cut the trip valves out of action, and be adapted, when closed, to open switch contacts included in a circuit leading to a controller for the current driving the vehicle, emergency switch contacts being, however, provided to permit the circuit to be re-established independently of the isolating cock contacts. In addition to the fluid-pressure resetting-means, mechanical resetting-means may be provided.

摘要： 267,224. Winter, H. J., Simmons, A. W., and Westinghouse Brake &. Saxby Signal Co., Ltd. Dec. 10" 1925. Fluid-pressure.-In order that a reduced braking pressure may be obtained on an empty or lightly loaded vehicle as compared with that on a loaded vehicle, a valve is provided adapted to cut off the supply of air to the brake cylinder when the pressure therein is a predetermined amount less than that in the auxiliary reservoir, the valve being by-passed under loaded conditions. The effective capacity of the brake cylinder may also be increased in unloaded conditions so that a relatively lower braking pressure is obtained with a given fall in train-pipe pressure. The triple valve 3 is provided with a valve 8 controlled by a piston 11 subject on its under side to the pressure in the auxiliary reservoir 1 by way of the passage 22 whereby normally the valve is held open against the pressure of a spring 13. A cock 6 is provided which in the position shown connects a passage 5 to the valve 8 by the passage 7 and also connects a chamber 23 to the brake cylinder 2 by a passage 24. Thus when the triple valve moves to application position air from the reservoir 1 is supplied to the brake cylinder and to the chamber 23 by the passages 5, 7 past the valve 8 and passage 9. When the brake cylinder pressure acting on the upper and larger area of the piston 11, together with the spring 13 is sufficient to overcome the auxiliary reservoir pressure acting below the piston, the valve 8 closes. In order to restrict the flow of air to the brake cylinder when a predetermined pressure has been reached therein, there may also be provided a valve 25 controlling an additional passage to the brake cylinder, and adapted to close when the brake cylinder pressure acting on a piston 28 overcomes a spring 22. For a loaded vehicle the cock 6 is turned to the position in which the passage 24 therein connects the passages 5, 9 thus cutting out the valve 8 and the chamber 23 which in this position of the cock is connected to atmosphere. The relative capacity of the passages 7. 24 in the cock 6 may be such that either the rate of filling of the brake cylinder or the time interval required to obtain the final pressure therein may be the same under light and load conditions.
