` HARRY E. LONG, OF LONDON, ONTARIOCANADA.

ELECTRICAL CONNECTOR.

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.

- HARRY LONG.
