Granted: 1903-12-31
Abstract: 23,150. Gordejeff, G. Oct. 26. Liquid-fuel fittings.-Relates to apparatus for burning liquid fuel such as naphtha, naphtha residues, petroleum, and the like, for heating steam boilers or other apparatus, by injecting the liquid through several apertures in front of the boiler, the apertures being so constructed that air is supplied to the issuing liquid in such a way that combustion takes place at some distance beyond the spraying-device ; also each spraying-device is self contained and may be put out of operation without affecting the action of the other sprayers. The spraying-devices 3 are inserted in apertures 2, within a cast-iron plate 1, which may be closed by doors 4. Castings 5, Fig. 2, are situated behind the apertures, and form the air ducts to the spraying-devices. A flange 7 is attached to the casting, and to it is screwed a ring 9 on which is mounted, by means of supports 10, a disc 11, having a circular aperture 12, which allows the end of the spraying- device to pass through it loosely. By this arrange. ment, the air entering the duct is not allowed to mix with the liquid until it is sprayed, and the liquid ignites at some distance from the disc 11 so that the latter is not excessively heated. The spraying-devices are pivoted upon supply pipes which may be turned so as to withdraw them. The door 4 may then be closed to prevent an excess of air from entering the furnace. An aperture 17 may be fitted to the plate 1, for allowing air to enter to the flame from below ; or a number of apertures may be made and closed by a single door, common to all the apertures, for regulating the air supply. The liquid may be sprayed by steam, gas, or air under pressure, but preferably by mechanical means.

Abstract: 27,924. Gibbs, G. Dec. 19. Electric railways on the third-rail or other systems. Switches. - Relates to a safety. device which automatically opens the feeding circuits in case of disturbance of the third-rail or conductor on electric railway systems. Fig. 1 shows the plan of the third rail and feeder circuits of an electric railway with the safety device fitted. In the Figure, 8 denotes the third-rail sections, 4 the generator, 5, 6 the bus bars or feeders connected to the different third-rail sections through the usual circuit breakers 7, 25 as shown, and 41 the return wire which is connected to the track rails. The device consists, in one form, of an auxiliary trip coil 11 for each circuit-breaker as shown applied at the left hand side of Fig. 1, or in another form, of an auxiliary trip coil circuitbreaker 40 in series with the main circuit-breaker 7 as shown applied at the right-hand side. These trip coils 11 are placed in an auxiliary circuit 9, 10, the conductor 9 being connected at intervals to contacts 12 arranged close to the third-rail. Figs. 3 and 4 show two forms of these contacts, 13, 20 being the contact pieces. In case of any accident, such as derailment, which brings the third-rail 8 into contact with the contact pieces 13 or 20, the trip coils 11 become energized and raise the armatures 22, thus breaking the feeder circuits. It is stated, that whereas the usual main circuit-breakers can only act when the current grows excessive, the auxiliary trip coils act with a small current and thus prevent destructive " arcs " from forming.

Filed: 1904-05-05
Granted: 1904-06-09
Abstract: 10,376. Jacobsen, N. May 7, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Signals, electric-bell; signals, indicator; alarms, burglar.-In electric alarm systems where the operation of one of a set of switches causes a signal to be given in an exchange and at the same time in separate buildings, the nearly simultaneous depression of different switches may lead to confusion in the signals at the latter places. To avoid this, while one switch is depressed, any other switch depressed just after it is prevented from operating the alarm, and can only move the corresponding indicator in the exchange. The depression of a switch A<1> causes the excitation of the electromagnet B<1> in the exchange, and the consequent motion of the rod T' and indicator V<1>. The rod T' presses the switch C<1> and closes the circuit containing the alarm apparatus in the separate buildings, and also a circuit containing an electromagnet M, the armature of which then displaces a bar S longitudinally. The rods T<1>, T<2>, T<3> pass through holes in this bar, and, when the bar is displaced, projections U on the rods prevent them from moving so far as to touch the switches C<2>, C<3>. If the apparatus is so arranged that, by the closing of the circuit, the electromagnet M only receives a momentary current, the bar S is held in its displaced position by a locking-device.

Title: Improvements relating to Vacuum Brakes for Railway and like Vehicles.
Inventor: CLOUD JOHN WILLS
Filed: 1904-12-05
Granted: 1905-04-27
Abstract: 26,472. Cloud, J. W. Dec. 5. Brakes.-Relates to improvements in the valve mechanism for accelerating the action of vacuum brakes, such as is described in Specification No. 14,318, A.D. 1904. In the arrangement shown in Fig. 1, a poppet valve 5 controls the communication between the train - pipe 1 and the "vestibule reservoir" 8. It is operated by a diaphragm 11 subjected on its lower face to atmospheric pressure from the reservoir 8 and on its upper face to the pressure of a spring in the operating-chamber 12, which is open to the brake cylinder by a pipe 13. When a sudden rise of pressure takes place in the train-pipe to apply the brakes, and the piston in the brake cylinder begins to move rapidly, there is momentarily a less pressure in the brake cylinder than in the train-pipe, and the valve 5 will consequently rise and open the reservoir 8 to the train-pipe. When the brake-cylinder pressure and the train-pipe pressure become equalized, the valve will close again. The Specification also describes the application of the improvements to the arrangement in which a slide valve is used to control the communication between the vestibule reservoir and the train-pipe. In this case also, the operating-chamber behind the diaphragm which moves the valve is connected by a pipe to the brake cylinder. Fig. 3 shows an arrangement in which the movement of the brake piston 2 operates mechanically a cock 31 so as to open the vestibule reservoir, connected at 7, to the train-pipe, connected opposite, through the port 32, and, after release of the brakes, to open the reservoir to the atmosphere through the passage 33 and port 36.
