Title: Improvements in electrically-controlled fluid-pressure apparatus, particularly applicable for operating brakes
IPC: B60T13/66
Filed: 1927-12-15
Abstract: 307,964. Tomlinson, A.. V., (Westing- house Air Brake Co.). Dec. 15, 1927. Fluid-pressure. - Electrically controlled fluidpressure apparatus particularly for operating brakes is controlled by a single control wire supplying current to an electrically actuated valve with the energizing winding of which a unidirectional current carrying device is associated so that the valve is only actuated when current of a predetermined character is supplied to the control wire The apparatus shown for a train of vehicles comprises a brake cylinder 5 supplied with fluid under pressure from an auxiliary reservoir 38, controlled by magnet valves 1, 2 controlled by a double-throw switch on the locomotive which is adapted to connect either pole of an electric generator to the single control wire 7 and the other pole to earth. The current through the wire 7 and the magnet valves 1, 2 to earth 28 is thus adapted to be reversed and this current according to its direction will pass through one of the rectifiers 3, 4 and one of the valves 1, 2. The resistance of each shunt circuit containing a rectifier is so small that not sufficient current passes through the other valve to operate it. In release position the valve 2 is de-energized and held open by a spring 20, thus connecting the cylinder 5 to exhaust through passages 33, 31, and the upper seat of the valve 1, which is energized and held on its lower seat. When the valve 1 is also de-energized by de-energizing the wire 7 its valve is moved to the upper seat and the auxiliary reservoir 38 is connected to the brake cylinder. By energizing the valve 2 the brake is held in lap position and graduated braking may be obtained. Graduated release may also be obtained by alternately moving the control switch from release to lap position. The brakes will be automatically applied if the current fails or the wire 7 is broken. The circuits of the valve magnets may be connected in parallel, the circuit of each magnet including a rectifier and being connected in series in the train wire which is connected to earth at the rear end of the train. The two rectifiers are reversely connected. Alternating current may be supplied to the train wire to operate both valves. For this purpose, each valve magnet may also be connected across the output terminals of a full wave rectifier, the input terminals of which are connected to the secondary winding of a transformer having its primary winding connected between the train wire and ground in series with a condenser. In a further modification the valves are connected in parallel and only one is provided with a rectifier and is adapted to be energized by low voltage current insufficient to energize the other valve. In this arrangement, the valve magnets on each vehicle may be connected in parallel with one another, the two parallel circuits being connected in series in the train wire which is connected to ground at the rear of the train.

Title: Improvements in electrical switchgear
IPC: H01H33/32
Filed: 1936-12-14
Abstract: 490,518. Gas-blast switches ; pneumatic actuation of switches. BRITISH THOMSON-HOUSTON CO., Ltd., and TRENCHAM, H. Dec. 14, 1936, No. 34301. [Class 38 (v)] In a circuit-breaker or isolating switch in which the casing containing the switch is filled with pressure gas, and mechanism for its operation includes a piston and cylinder or like device enclosed in, or communicating with, the casing and having its pressure side in communication with the casing-interior, the exhaust side of the piston communicates through an operating valve with atmospheric pressure so that the casing-pressure is utilized to open and close the contacts. The movable contact 2 is guided at 7 for horizontal movement by means of a piston 10 in a cylinder 11 on one wall of the pressure-gas filled container 3. The front of the piston 10 communicates over a narrow annular orifice 22 around the piston-rod 12 with the casing-interior, and over a pipe 24 and valve 25 with the atmosphere. A narrow inlet 21 to the casing 3 is provided at the back of the piston 10, and a conduit 17 leads thence to a chamber 16 which can be opened by valve 17a to communicate over ports 19 and passage 20 to atmosphere. To open the switch, solenoid 18 is energized to open valve 17e, so putting chamber 16 and, over conduit 17, the back of piston 10 to atmosphere. The casing-pressure acts through orifice 22 to move piston 10 to the left, and also sends a blast of gas through passages 13 between baffles 14 and through pipe 15 to chamber 16, so blowing out the arc. The switch is reclosed by energizing solenoid 26 to open valve 25, whereupon gas-pressure acts through orifice 21 and pipe 17 to move the piston 10 to the right. The orifices 21, 22 are of such size that they do not affect the opening and closing operation, respectively. Piston rod 12 may be extended beyond the casing wall to operate limit-switches for de-energizing the solenoids 18, 26 at the end of the opening and closing movement, respectively. The lead-in bushings 4, 9 have enclosures 27 communicating with the casing over holes 28 to provide additional gas-reservoirs. The cylinder 11 and chamber 16 may be located outside the casing, in which case orifice 21 would lead to the latter over a conduit similar to 17 and the latter would be externally arranged. Switches of existing design may be connected over bushing-insulators to pressure-air filled switchgear, such as bus-bar chambers serving as reservoirs. Specification 123,812, [Class 38 (v)], is referred to.

Fig. 5 shows a modification in which the back 226 and seat 228 are separately pivoted to the support 220 and the connecting links comprise top links 232 and front links 284, 234 pivoted together at 239 the links 284 being in rigid connection with the guiding links 242. The controlling elements 250 in rigid connection with the guiding links 242 are pivoted to adjusting members 290 which may assume two positions either in prolongation of the controlling elements 250 or of the controlling links 252 so varying the inclination of the leg rests 246 independently of the movement of the link system. The guide links 242 and controlling elements may form a unit which may be pivoted in slots in the sides of the support 220 which in this case is a casing and serves to hide the mechanism in the upright position of the chair. As shown in Fig. 12 the controlling link 551 may be pivoted to a second link 553 pivoted on the same pivot 548 as the leg rest and seat and means such as a clampable rod 543 may be used to vary the inclination of the leg rest 546. Movement of the link system will not vary the relative inclination of the leg rest with the seat until a cam surface 508, which may be on the second link 553 or on the controlling link 551, comes into contact with the leg rest. Locking means may be provided for locking the chair in the desired adjusted position. The support may be mounted on wheels or it may be foldable.
