Title: Improvements in Recoil Brake Apparatus for Guns that Recoil on the Carriage.
Inventor: YINGLING FRANK BEAM
Filed: 1905-11-15
Granted: 1906-04-12
Abstract: 23,513. Yingling, F. B. Dec. 1, 1904, [date applied for under Patents Act, 1901]. Field carriages.-Relates to recoil apparatus of the kind described in Specifications No. 27,093, A.D. 1903, and No. 21,929, A.D. 1905, in which the recoil stroke is adjusted according to the elevation of the gun. Fig. 1 is a side elevation, and Figs. 2 and 3 a sectional front elevation and plan, respectively, of one construction. The brake cylinder 6 recoils with the gun, and the liquid passes from the front to the rear of the piston 7 through ports V. A cylindrical valve 9, rotatable upon the piston-rod 8, is arranged gradually to throttle the ports V during the recoil stroke. A crank 14, mounted upon the forward end of the valve stem, is actuated by a crank 16 on rocking shaft 17. A roller 20 on the crank 18, which is caused to slide longitudinally on the shaft 17 by an aim 19 projecting from the cylinder 6, works against a fixed cam surface 21 and rocks the shaft and thus regulates the valve 9. A rack-bar 25, pivoted to the carriage at P, as the gun is elevated rotates the gear 24, which, through a helical gear 22, rotates the cam plate 21, so that the correct contour for any given elevation is presented to the roller 20. In modifications, (1) the cylin. drical valve is mounted in the cylinder 6, and the latter is rotated during the recoil stroke by a roller guided between two rotatable longitudinal cam bars, and (2) the wall of the cylinder is formed with a series of grooves of varying lengths, or the grooves may be formed in a throttling-rod, working within the hollow piston-rod, so that any one, or more, of the grooves may be used for the passage of the liquid from one side of the piston to the other. The cam surfaces, where such are used, or the grooves, are so arranged that the initial opening of the valve is constant for all elevations, and may be increased, during the recoil stroke, before the commencement of the throttling action. Modifications are also described in the means for rotating the cam surfaces, or the piston-rod in the third modification, as the gun is elevated.

Patent GB-190601116-A (GB)
Title: Improvements in and relating to Vapour Electric Apparatus.
Filed: 1906-01-15
Granted: 1906-12-13
Abstract: 1116. British Thomson-Houston Co., [General Electric Co.]. Jan. 15. Cut-outs; distributing; lighting, systems of.- When a number of vapour electric devices, such as mercury - vapour lamps, are worked in series, to avoid the initial high resistance and to prevent mutual disturbance in case some of the devices fail to start, an automatically-controlled shunt path is provided in connexion with each. The shunt initially forms a short-circuit, and gradually increases in resistance until the vapour device is properly started. Fig. 1 shows one form of apparatus. Current flows' from the supply main 32 through a double solenoid 18 to the anode 2 of the vapour lamp 1, along a starting-filament 6 to the mercury cathode 3, and through a coil 7 an d a electro-magnet 12 to a wire 33 leading to the next lamp 34. The shunt path is formed of a pair of carbons 16, 17 initially in contact. When the current traverses the solenoid 18, it raises a core 19, provided with a dash-pot, and attached to a clutch 30 arranged to grip the carbon 16 during the upward movement: A stop 31 sustains the clutch in its lowest position. An arc is formed by the separation of the carbons, and gradually increases in length as the core 19 is raised, thus gradually increasing the voltage supplied to the lamp, and giving the coil 7 time to disconnect the starting-filament 6 by drawing down the floating mercury vessel 5. If the lamp fails to start, contacts 15, 25 make a short-circuit round it. If the lamp starts, the electro-magnet 12 attracts its core 14 and prevents the formation of the short-circuit. Two spring clips 9, 10 and a layer of insulating- material 11 form a short-circuiting cut-out in case of great excess voltage. Similar controlling-apparatus is associated with the other lamps of the series. They are preferably caused to start successively by giving the dash-pots different timeconstants. Fig. 2 shows a modified apparatus having a carbon disk 41 lifted by the solenoid core from its original position in contact with two carbon blocks 42, 43. The rise is checked by a dasb-pot 39. A self-reducing resistance 44 may be placed across the mains to short-circuit the lamp in case of failure to start. The stop 40 is preferably made of lead or other easily-melted metal, to prevent the arcs from continuing beyond a certain time. Fig. 3 shows a further modification, in which the movable core 48 first lifts both the upper and lower carbons, the lower carbon 47 then falling back under the restraint of a dash-pot 46. Specification No. 27,638, A.D. 1904, is referred to.

Granted: 1906-12-13
Abstract: 18,009. Mouhlen, J. Aug. 10. Plug cocks; repairing, facilitating; tampering with valves, preventing; casings.-A cock for controlling the supply of water to a tap a and to a service pipe h which extends beyond the tap, is adapted to allow of easy repair of the tap. The cock e has a perforated centre and three ports i, k, l, Fig. 3, which may register with the main supply pipe c or with the inlet pipe d of the tap a, and three ports m, n, o, Fig. 4, which may register with the extension pipe h. Normally, the cask e connects the pipe c to both the tap a and pipe h, but on rotating the cock the supply to the tap a is turned off ; the supply to the pipe h is then turned off and the tap a is again supplied. A further rotation of the cock e cuts off the pipe e but allows the pipe h to be emptied through the tap a. In order to prevent the tap a from being unscrewed from the pipe d, and to prevent the nut t which connects the upper part to the body of the shell from being unscrewed, a ring f is freely mounted on the tap and is provided with a projection r, which normally engages a recess u in the nut t, and with an extension which engages a recess in the plug e and abuts against a clip e<2> on the plug. When the cock is in its shut position, this extension registers with a recess in the clip e<2>, so that the ring can be moved to the right thereby releasing the nut t from the arm r and also enabling the tap a to be unscrewed from the pipe d.

Title: Improvements in and relating to Signalling Systems for Railways and the like, and Apparatus therefor
Filed: 1906-09-04
Granted: 1907-12-04
Abstract: 19,737. British Thomson-Houston Co., [Kintner, C. J.]. Sept. 4. Electric railways and tramways. -Semaphore signals are operated and locked at the safety position by current derived from the power circuit on electric railways and the like, the circuits being controlled, as described in Specifications Nos. 18,278 and 18,279, A.D. 1906, by a relay on the track energized from a second source of energy, said relay serving, when energized, to connect the sectional third rails supplying power for the train motors to the feeder, and, when de-energized, to connect the signal-operating motor to the power feeder, this circuit being broken by the armature of a locking electro-magnet when the signal has reached the safety position, in which it is locked by the armature until the track relay is again energized and the locking-circuit thereby broken. Fig. 1 shows parts of two sections of track with a train on that to the right of the Figure. The main feeder F receives energy from the generator D, and the track rails serve as the return. The train motors e draw their energy from the sectional third rails 3, which are connected to the feeder F through the armature a of the magnet m on its front contact. The magnet m is energized by the battery h when a train is over the circuit-closing rail Z, such as is described in the Specifications referred to above. When no train is on a section, the armature a of the relay m is on its back contact r', and the circuit is closed from the feeder F by the lead 5 to the operating-mechanism of the home signal S and to the operating-mechanism of the distant signal s at the entrance to the rear section. The signaloperating mechanism consists of a motor M, geared to the spindle carrying the signal arm. The signal is normally held at 'safety' as shown by the arm g engaging the armature d of the magnet n, which is energized through the lead 5, contacts at left of armature d, and lead 7. When the switch armature a opens the contact r<1>, this circuit is opened and the signal is released and moved to 'danger' by the weight W hanging on a cord over a pulley. When the contact r<1> is again made, the motor circuit is completed through the lead 5 and contact p to the motor which drives the signal to 'safety.' The arm g carries a contact which closes the circuit to the magnet n at the contact o. This magnet draws its armature, locks the signal at 'clear,' closes a maintaining-circuit at the contacts at the left of the armature d, and breaks the motor circuit at the contact p. The motor is arranged to drive the arm g a short distance beyond its locked position to which it is drawn back by the weight W.
