l u ELECTRICAL CONNECTOR. No. 278,346. e, Patented Mey 29,1883. Y




SPECIFICATION forming part of Letters Patent No. 278,346, dated May 29, .1883. Application tiled November 6, 18852. (No model.)

To all whom it'may concern:

Beit known that I, HARRYE. LONG, of London, in the county ot' Middlesex and Province of Ontario, Canada, have invented a new and useful Improvement in Electrical Gonnectors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which frm part of this specification.

My invention relates to an improvement in electrical connectors, more especially designed to-be` used for connecting in a closed circuit the cars'of a railway-train `and the locomotive drawing them, having a battery and an electric bell iu circuit, so that if the circuit be broken at any point in the train, either by design or by accident, the locomotive-driver will be signaled throughthe bell to stop.

My invention consists in the peculiar construction of a plug and a spring-socket, of each of which one is to be attached to the flexible wires or cables running through each car, so that they can be quickly engaged with correspondin g devices in adjoining cars to complete the circuit through the train.

Figure l is a perspective view ot' my connectors detached or uncoupled. Fig. 2 is a horizontal section ofthe same at x m iirFig. 1. Fig. 3 is a similar section ot' the same coupled, to show why they will not uncouple in the sagging of the cable.v Fig. 4 is a vertical longitudinal section at y y.

In the drawings, A represents the male plug ot' myconnector, having at one-end a socket, a, to receive the terminal of'a wire or cable intersected by a tapped hole, in which is inserted a binding-screw, a', to secure them together. The other end ot' the part A terminates in anoval or elongated head, A', having a contracted neck, as shown at c'.

B is the socket part, having ahole, b, in the l base to receive the terminal, which is secured thereto by a binding-screw, b". The part B is composed'of two parallel plates, with 1an interposed block, B', `at one end, which forms the base, to which the terminal is coupled. A

C C are two leatsprings,`one end of each ot whichis secured to the block B in such a manner that their free ends may play between the stationary plates. The -free end of each is 'formed with a curved or convex boss, c, on the when sagging, as isshown in Fig. 3. They can bequickly coupled by pushing the head A between the springs (l C in aright liuc. Preferably they should be made of steel, and may be protected by covering with a non-conductor, it' desired.

What l claim as my invention is- An electric connector for train-telegraphs, consisting ofa plug having'an elongated head and contracted neck, and a socket part having its top and bottom formed ot' stationary plates and its sides of leaf-springs, the plates and springs being secured to an iuterposing end block,-as shown, and the springs being protected by the stationary plates, and provided at their free ends with a convex boss adapted to enter and engage the contracted neck of the plug when the latter is forced into the-socket part, as and for the purposes set forth.
