Title: Improvements in Safety Devices for Strong Current Overhead Conductors.
Inventor: VALK CHRISTIAAN CORNELIS VAN D
Filed: 1903-08-10
Granted: 1903-11-26
Abstract: 17,367. Valck, C. C. van der. Aug. 10. Electric railways and tramways.-In a safety coupling for use on overhead electric conductors to cut off current from a broken wire, two adjacent wires 6, 7, Figs. 3, 5, and 6, are secured to two insulating-pulleys 4, 5 mounted loosely on a spindle 3 within a metal casing 1. The inner faces of the pulleys are recessed to receive brass contactstrips 10 which are each pressed against the end of one of the wires 6, 7 by bolts 11 and washers. When the wires 6, 7 are in tension, as shown with regard to the wire 6 in Figs. 5 and 6, the strips 10 are pressed by springs 14 against each other or against a central strip 23 in connection with the feeder 24 which supplies the current. In this position, shoulders 16 on the pulleys bear against square stop-pins 15 on the casing. When a wire breaks, a strong spring 17 placed in central recesses in the pulleys rotates the loose pulley, and afterwards forces it away from the other when two projections 19 upon it have moved off corresponding projections 20 on the casing. Figs. 5 and 6 show the pulley 5 in this position, the wire 7 being assumed broken. Connection of the broken wire with the feeder, or the other wire is thus broken at the strip 10. In case the above device should fail and the broken and unbroken wires remain connected, provision is made for earthing the unbroken wire. For this purpose, springs 25, depending from an insulating-block 22 and connected either to the feeder 24 or to the opposite strips 10 or wires 6, 7, are arranged to contact with the earthed pins 15 when the pulleys rotate. The springs 25 normally tend to contact with the pins 15, but are held back by the shoulders 16 bearing against insulating-pins 27 projecting from the springs 25 through holes in the pins 15. Contact at the proper times is ensured by the action of other shoulders 31 on the springs 25 and by means of insulating-catches 29. The casing 1 and the pins 15 are earthed through the suspending-eyes 2 and the poles &c. The pins 27 may be dispensed with and the springs 25 arranged to contact with the pins 15 only when pressed up by the shoulders 31, or the springs may be replaced by contacts which touch the casing only when the pulleys rotate.

Title: Improvements in Locks or Fastenings for Doors
Inventor: PECHY GASPAR VON
Filed: 1903-09-04
Granted: 1904-08-11
Abstract: 19,102. PÚchy, G. von. Sept. 4. Sliding bolts; latches.-A bolt 2, enclosed in a casing 1 fixed to a door, is guided on a roller 3 projecting through a slot in the bolt. A bellcrank lever 6 pivoted to the casing is connected to the bolt by a stud 7 which projects from the vertical arm of the lever and engages a slot 8 in the bolt. The arm 6<1> of the lever is counterweighted and coupled to a cord 10 passing over guide-pulleys to the point from which the latch is operated. Normally, the counterweight 9 keeps the bolt in engagement with the staple; by pulling the cord 10, the lever is operated to retract the bolt. A catch device is employed to retain the bolt in the retracted position. In a casing 14 secured to the wall of the casing 1 is pivoted a bucket 16 containing a loose ball 17. An arm 21 forming a knee joint is coupled to the lever arm 6<1>, and is provided with a projection to engage behind the bucket 16. When the arm 6<1> is raised to withdraw the bolt, the bucket 16 is tilted, and the ball 17 is thrown through a hole in the casing 14 against the front wall of the casing 1. If the cord 10 is now released, the arm 6<1> is prevented from falling by the ball. If the cord is pulled before it is released, the projection on the arm 21 is drawn away from the bucket, and the bucket and ball fall to their original position, allowing the arm 6<1> to fall on the release of the cord. A spring 23, provided with a stop abutting against the casing 14, presses on the lever arm 6<1> in the raised position.

Title: Improvements relating to Targets.
Inventor: WEBB WILLIAM WALTER GERALD
Filed: 1904-06-20
Granted: 1905-05-11
Abstract: 13,896. Webb, W. W. G., and Hall, J. June 20. Targets.-A target consists of a number of segments a mounted concentrically around a bull's-eye b. Each segment, including the bull's-eye, is carried at a suitable distance in front of a pair of supporting-plates c, by means of a plunger e and a pair of guide-pieces f which pass through the supportmg-plate c. The segments a are preferably arranged in different planes to prevent binding of adjacent segments by bullets striking the division lines between them. Each segment is returned to its initial position, after recession under the impact of a bullet, by means of a spring g fitted to the plunger e. In conjunction with the extremity of each plunger, is arranged an electric switch comprising a fixed contact-piece i and a spring contactpiecej, normally held out of contact by a nut or collar k fixed to the plunger e. After a segment has been struck, and during its consequent recession, the contact-pieces i, j are permitted to engage and complete a circuit through electric signalling and recording apparatus. The signals and records are made automatically by electrically-actuated mechanism connected with the segments. An electromagnet m, Figs. 5 and 7, arranged in each of the circuits passing through the target switches, releases the catch n of a counterpoised disc o when a circuit is made. The disc, on being released, drops into position behind an aperture in the front of the casing q enclosing the mechanism. The discs are restored to their original positions by pushing in the sliding bar, fitted with a handle v and bearing a number of trip-pieces t which engage with lever-like projections w from the discs. The discs, when raised, are held by the catches n. For recording the number of hits, a dial x, having its face suitably divided, is employed. The finger of the dial is connected to a ratchet-wheel y actuated by a pawl z, which is in turn operated by an electromagnet 1. All the segments of the target are arranged to actuate this electromagnet when struck by a bullet, thus causing the finger of the dial to be advanced one division for each hit. The current for actuating the electromagnets is supplied by batteries s. Connection is made between the target and recording-apparatus by a cable provided with the requisite number of wires. A cardboard screen 5 can be mounted in front of the segments a to show the exact position of each hit.

Fig. 3 is a rear elevation, and Figs. 2 and 4 side elevations. The projectile 1 is carried by a tray a, running on rollers w and rails r in the transverse recess 4 of the trolley s. An endless chain b passes over chainwheels c, v carried by the tray a. On the shaft u of the wheel v is mounted a ratchet-wheel g normally held by a pawl o connected with the spring rod n by a crank 7, so that the tray a may be moved forwards by rotating a chain-wheel e on a shaft y carried by the trolley s, until the rod n strikes the breech of the gun and raises the pawl, 1, permitting the chain b to move independently of the tray. A bolt m springs into the latch 6 and locks the tray a to the breech of the gun. As the tray moves forward, a bell crank j, actuated by the camgroove h and roller i, draws back the rod k and crank l, and lowers the plate f, pivoted at 5, into the breech of the gun. A " pusher " d, carried forwards by the chain, slides the projectile forwards into the barrel ; the first component 2 of the explosive charge is then laid on the tray, and moved forwards, driving the projectile before it, by a second "pusher" x which has been carried to the rear as the " pusher " d moved forwards ; the second component 3 is similarly treated, and the whole rammed home by a rammer p. The motion of the wheel e is then reversed, and one of the pushers, by engaging a spring bolt q (bevelled on its underside to give to the upward motion of the pushers), locks the chain so that the tray may be withdrawn to its initial position.
