Claims. (01. 173-340) This invention relates to a connector for connecting up a local electric light circuit to a welders cable. In conducting welding operais frequently located in situalt would be very ighting.

One of the objects of this vide a connector of to the welders cable, and which will supply current to a lamp which can be supported in a position to throw light on the work.

A further object of a device of this kind, to the exterior of the special tools.

In practicing the invention, an insulated tapered spur or contact device is preferably emthe invention is to provide which can be readily applied welders cable without using of the return wire from the lamp circuit.

Further objects of the invention will appear hereinafter.

contribute to produce an efficient connector for temporary lamp circuit.

A preferred embodiment of the inventionis described in the following specification, while the broad scope of the invention is pointed out in the appended claims. I I

In the drawing:

Fig. i is a perspective illustrating a welders welders cable by means of a connector embodying this'invention. Fig. 1 indicates the work and a support for the same, and certain parts broken away.

in the formof a long screw, the shank In practicing the invention I provide a connector I that preferably has a body, the axis or which is intended to extend substantially parallel with the welders cable 2 to which it is to be attached. This body is provided with means for securing it to the exterior of the cable, which is a sheath 3 of insulation or insulating material. The body I is preferably constructed so that it can be readily applied to the cable by moving the same laterally toward the cable, and at the same time manipulating the cable so as to engage it between two hooks 4 which extend out at the side of the connector. These hooks are spaced nector will attach itself to the cable. In this connection attention is called to Fig. 2, indicating that at the ends of the bills 5 of the hooks, a throat such as the throat G is formed, through which the cable must pass, and this throat is of slightly smaller width than the diameter of the ca le.

In order to eflect the electrical contact with the conductor 9 within the welders cable, I prefer to provide a tapered conical spur in which may be in his hand and applies the electrode l9 to the placewhere the weld is to bemade :The electric light cord I4 is held in a cylindrical socket or bore 20 that preferably extends into the body I from oneend in which an insulating bushing 2| may be provided. In the present instance the return wire 22 passes across the bore 23 of the insulating block or bushing ll, Q

, and is carried through a notch or socket 24 near the forward end of the body I, from which point the bare wire 25 extends under a terminal or binding screw 26 which is threaded into the end of the body I to groundthis wire at the connectiOn. -1

It should be understood that the body I .is preferably constructed of metal so as to makeiit easy to ground the lamp circuit at the connector if it is desired to ground the circuit at that point.

It is merely necessary, however, that when the connector is lying on its support, a ground will be established for the return wire 25. It is most convenient to have the body I made of metal because merely by lying upon a grounded sup port such as the work, or a grounded table ll, a proper ground will be established.

In many cases where the welder is working on large work such as the welding of tubing or boilers, or other large'industrial parts, the body can merely be permitted to lie on the work itself to establish the ground. 30

Many other embodiments of the invention may be resorted to without departing from the spirit of the invention.

What I claim is:

1. A connector for establishing an electric light circuit fed by an insulatingly sheathed welders cable, comprising an elongated body having means for attaching the same to the exterior of the insulating sheath of the cable with the longitudinal axis of the body substantially parallel with the axis of the cable, said body having an insulated spur of conducting material to penetrate the insulating sheath to contact with the conductor within the cable,'said spur having an insulated terminal for attaching a wire for the electric light circuit; and a second terminal grounded on the said body for connecting the other wire of the light circui 2. A connector for establishing an electric light circuit fed by an insulatingly sheathed welders cable, comprising an elongated body having means formed with a gap on its side for enabling the body to be attached to the exterior of the insulating sheath of the cable by moving the body laterally toward the cable with the longitudinal axis of the body substantially parallel with the axis of the cable, said body having an insulated spur of conducting material to penetrate the inavamst co i,

sul ting she th 'to contact with the conductor wi the able, said spur having an insulated terminal for attaching a wire for the electric light circuit; and a second te al grounded on the body for connecting th other wire of the light circuit.

3. A connector for establishing an electric light circuit "fed by an insulatingly sheathed welders cable, comprising a body having spaced hooks projecting from the body enabling the body to be attached to the exterior of the insulating sheath of the cable by a lateral movement of the body toward the cable, said body having an insulated spur of conducting material to penetrate the insulating sheath to contact with the conductor within the cable, said spur having an insulated terminal for attaching a wire for the electric light circuit; and a second terminal grounded on the said body for connecting the other wire of the light circuit.

4. A connector for establishing an electric light circuit fed by an insulatingly sheathed welders cable, comprising a body having a pair of spaced hooks, said hooks projecting from said body and extending in opposite directions at the side of the body, and each hook having a gap beyond its bill capable of passing a cable, said hooks enabling the body to be attached to the exterior of the insulating sheath of the cable by a lateral movement of the body toward the cable, and bycompressing the cable, said body having an insulated spur of conducting material to penetrate the insulating sheath to contact with the conductor within the cable, said spur having an insulated terminal for attaching a wire for the electric light circuit; and a second terminal grounded on the said body for connecting the other wire of the light circuit, said body having an insulating bushing carrying the insulating terminal, and having a bore through which the electric light wires may be passed in securing the same to the body.

5. A connector for establishing an electric light circuit fed by an insulatingly sheathed welders cable, comprising an elongated body having means extending laterally therefrom to partially encircle, and attach, the same to the exterior of the insulating sheath of the cable with the longitudinal axis of the body substantially parallel with the axis of the cable, said body having an insulated spur of conducting material to penetrate the insulating sheath to contact with the conductor within the cable, said spur having an insulated terminal for attaching a wire for the electric light circuit, and means associated with the electric light circuit for grounding the same beyond the lamp.
