Title: Improvements in Valves.
Inventor: LINDEMANN ERNST
Filed: 1903-08-22
Granted: 1904-06-02
Abstract: 18,176. Lindemann, E. Aug. 22. Pump valves.-A check valve which can be used either as a delivery or suction valve for waterpumping engines &c. consists of a thin flexible metal plate a covering openings d in a valve seat f and provided with openings b. The valve is guided by studs e, which pass through elongated slots c in the ends of the plate a, the deflection required for operating the valve taking place only at that part of the plate a which is rendered more flexible by the openings b, while the part of the plate, which directly closes the openings d, rises and falls parallel to the valve seat. The force required to operate the valve without undue shock is increased or diminished by varying the thickness of washers e<1> or by spiral springs used instead of the washers. If the plate a is clamped, it is preferable to fix it at its centre, the portion only of the plate which closes the openings d being capable of moving from and on to its seat. In another form, the outer edge of a circular plate closes the openings d, while the openings b are arranged within the inner periphery of the plate, and, in addition, a stop is arranged to limit the amount of rise of the valve. In another form, the more flexible parts of the plate are reduced in thickness from the inner periphery to the centre of the plate. In a modification, there is only one opening b, which is of spiral shape.

Title: Improvements in and connected with Telegraphic and other Transmitting Apparatus
Inventor: ARMSTRONG JAMES TARBOTTON
Filed: 1904-11-05
Granted: 1905-11-02
Abstract: 23,952. Armstrong, J. T., and Orling, A. Nov. 5. Telephone systems; telegraphs. -Relates to the arrangement of telegraphic an telephonic transmitting-apparatus for use with submarine and other cables. The transmitting-circuit includes one or more induction coils and an "interrupter" or a microphone, which causes a fluctuating current to pass through the induction coils so that "extra" currents are induced and impressed on the current in the line-wire. Fig. 1 shows the telegraph transmitting-arrangements, including the induction coil c, "interrupter" d, and transmitting-key e, provided with an insulated plate o, which, when the key is depressed, connects the line-wire f through the contact j with the coil c, key e, battery b, and line-wire g. The line-wires f, g are thus in series with the transmitting- circuit, but this is the case only when the "interrupter" d is in the 'break' position. When the "interrupter" is in the make' position, as shown in Fig. 1, the line-wires f, g are shortcircuited between the points h, i. Thus, at every ' break,' the direct " extra" current and the battery current pass through the whole circuit, while at every make' the line-wires receive a portion only of the inverse "extra" current and of the battery current. The receiver may be a telephone p. The contacts of the interrupter" d are short-circuited by a condenser l or may be enclosed in a vacuum to prevent sparking. Fig. 4 shows the telephone transmitting-arrangements, the microphone d<x> being in series with the coil c, hook switch ex, and battery b. The line-wires f, g are connected in multiple with the microphone. The fluctuations of current in the coil c caused by the microphone give rise to "extra" currents which divide between the line-wires f, g and the microphone.

Patent GB-190428878-A (GB)
Title: Improvements in Mechanism or Means for Controlling Air Brakes.
Inventor: EVANS-JACKSON JOHN EDWARD
Filed: 1904-12-30
Granted: 1905-02-23
Abstract: 28,878. Jackson, J. E. Evans-, [International Air Brake Co.]. Dec. 30. Brakes, pneumatic-pressure. Relates to a device attached to the triple valve for venting the brakecylinder exhaust to the atmosphere only when the train-pipe or auxiliary-reservoir pressure is greater than a predetermined minimum, and also to an attachment to the driver's valve which maintains train-pipe pressure while the valve is in lap position. The former consists of a diaphragm 13, Fig. 1, exposed on one side to auxiliary-reservoir or trainpipe pressure through the pipe 9, and having attached to it on the other side a block 14 with feet 46 adapted to rest on the casing 11, which has open vent holes 12. Under normal pressure, the block presses on the spindle 15 of the exhaust outlet valve 16 and keeps it open, but, on application of the brakes, the spring 17 overcomes the reduced pressure on the diaphragm and closes the exhaust until the predetermined pressure, which is regulated by the spring 17, is restored for releasing the brakes. A cock 7 cuts out the device. In conjunction with the above device, an addition is made to the driver's valve, as shown in Figs. 3 and 4, the plate 27 being inserted between the feed-valve 32 and the body of the valve, and having openings 25,26 for the train-pipe and mainreservoir channels respectively. A passage 30 leads from the train-pipe channel to the casing of the valve plug 29, which is adapted to connect it with a channel 31 leading to a port 37 in the rotary valve seat, which, in lap position, is open to the main reservoir. The plug 29 contains a valve 33 held on its seat by a spring 36 kept in position by a sleeve on the nut 34, which also guides the valve spindle. The joint is kept tight by a screwed cap with spring 35. The valve spring 36 is regulated to admit air to the train-pipe just under the release-controlling pressure. When the driver's valve is in lap position, all the ports but 37 are closed, and, by the opening of the plug 29, the train-pipe channel 25 is charged to a pressure slightly below the brake release-controlling pressure through the valve 33, channel 31, and port 37.
