ELECTRIC CONNECTION.

Speci-cation of Letters Patent.

Patented Apr. 1, 1919.

Application led December 13, 1917.- Serial No. 206,894.

To all whom it may concern.'

Be it known that I, WILLIAM H. BROWN, a citizen `of the United States, residing at Philadelphia, county of Philadelphia, and State of ennsylvania, have invented a new and useful Improvement in Electric Connections, of which the following is a full, clear, and exact description, reference 'being had to the acompanyin drawings, which form a part of this specl cation.

My invention relates to that form of electric connection whereby an electrical conductor, such as an insulated wire or cable, is detachably connected to a binding post or other terminal for the passage of an electrical current thereto.

In my improved connection a screw cap of insulating material is slipped on the end of the wire or cable to be connected; the cap is then screwed on to a binding post of conducting material and the connection positively and permanently made as will be hereinafter described.

My improved connection forms a perfect protection from water, heat, dirt, etc., and provides a positive connection for the conductors, being at the same time extremely simple in both construction and operation.

Referring to the accompanying drawings, in which I have illustrated a preferred embodiment of my invention- Figure 1 is alongitudnal view of my connection.

Fig. 2 is a longitudinal view, partly in section, of my connection showing the connection made.

Fig. 3 is a longitudinal view, partly insection, showing the method of'applying the cap` to the binding post.

ig. 4, is a cross sectional view of the binding` post.

he terminal cap 0;, composed of an4 insul lating material, for example, bakelite, is divided into two chambers b and c by the partition d, which is provided at the center with the hole e. The walls of the chamber b are made smooth, while the chamber c is internally threaded.

The binding post f, composed of a conducting materia for example, brass, is threaded. for a distance from one end as at g and is provided on one side with the groove h, extending lengthwise for a distance from the threaded end.

The chamber b in the cap is adapted `to receive the cable z'. The wire j carried in the cable is adapted to pass through the hole e into the chamber c and into the groove h, when the cap is screwed onto the binding pos In practice, the insulation is removed from the wire for a certain distance and the cap placed over the end until the clean wire extends through the hole e and into the chamber 0. The cap is then started on the binding post, care being taken to insert the end of the wire in the slot h in the post, as shown in Fig. 3. The cap is then screwed down tightly, completing the connection. As the cap is screwed down, the wire travels along the groove h which, being in the side of the binding post, is oil' center from the hole e. The wire entering the center of the chamber c is thus deflected to the side of the chamber, as shown in Fig. 3. When the cap is tightly screwed down on the post, the end of the post is forced into positive contact with an intermediate 4portion of wire, the V filling chamber c and the end of the wire filling the slot in the binding post. The connection requires a minimum of space, it may be readily made or broken, and when made a pos1t1ve -and permanent connection 1s assured.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is:

1. An electrical connector comprising a wire-containing cable, a terminal member exteriorly threaded and a cap open at both ends and provided with an apertured partition between its ends to form two chambers, one chamber being interiorly threaded to receive the terminal and the other adapted to receive the cable, the terminal member having a longitudinally extending groove intersecting its threads and adapted to receive the wlre extending beyond the cable through the apertured partitions and b'end it later- 'ally and also feed it along the groove as the hollow cap forming a ychamber adapted to receive the terminal, and a wire extending through an axial hole inthe end -wall of thev cap chamber and engage said'groove,'where by, as the cap is screwed upon the terminal, the end of the wire feeds forward in the groove and is bent laterally betweenthe hole cap being a apted -to receive an insulated wire cable the uncovered end wire of which is adapted to extend through the perforated 15 partition, the other hollow end of the cap being interiorly threaded, and a terminal eX- teriorly threaded to engage the threaded end of the cap and provided with a longitudinally extending groove adapted to receive 2o the projecting wire end and bend it laterally to confine it between the terminal and 'the cap as the cap is screwed to position on the terminal.

lln testimony of which invention, l have 25 hereunto set my hand, at Kennett Square, Penna., on this 11th day of December, 1917.

. WILLIAM H. BROWN.
