GONNECTER FOR ELECTRICAL CONDUCTORS. 4

Application filed March 14, 1925. Serial No. 15,478.

This invention relates generally 'to connecters for electrical conductors and more particularly to a device of this general nature which can be readily placed in gripping contact with any portion of a conductor.

The invention consists of a connecter formed from a sheet metal blank cut with a minimum degree of waste and a correspondingly economical use of metal. A tongue member is formed along the longitudinal center of thel blank and the laterally separated sections thus provided in flanking relation to the tongue member are looped backwardly in position to grip a conductor Iggainst the lower face of the tongue mem- A'feature of the invention resides in' an angular extension at the free end of the tongue member which forms withthe looped 0r rearwa'rdly turned sections a recess orindentation in which to receive a conductor and by the pressure exerted against the conductor lift the ton ue member and permit the conductor to s 1p into gripped relation between the tongue member and the curved sections.

Other features of the invention will be hereinafter referred to.

In the drawings, in which a preferred embodiment of the invention has been selected for illustration,

Figure 1 is a perspective view on an enlarged scale showing a conductor connecter embodying the invention.

Figure2 is a plan view of a blank from which the connecter shown in Figure 1 is formed.

Figure 3 is a view in side elevation of the device shown in Figure 1.

Figure 4 is an end view of the device shown in Figure 3. I

Figure 5 is a view in longitudinal section of the device shown in Figure ,3.

Referring to the drawings for a more detailed description of the invention, a blank is shown in Figure 2 taking the form of a section 10 of a strip of sheet-metal having a tongue 11 formed along the median line thereof and terminating at a point 12 spaced from a bridging member'13- that is retained to form a connecting member between the lateral sections 14 and 15 of the strip. The lateral sections 14 and 15 by this arrangement extend to a considerable extent beyond the end 12 of thetongue 11 thereby providing for the loopingor turning of the lateral sections 14 and 15 rearwardly into substantially parallel relation with the intervening tongue member as is clearly shown in F ig ures l and.3 of the drawing.

In order to suitably stiffen or reinforce the tongue member 11 as well as the lateral elongated sections 14 and 15, indented grooves 16and 17 are formed in the respective parts.

In the formation of the completed device shown in Figures 1 and 3 of the drawing, the ffee end 12 of the tongue member 11 is bent outwardly or-upwardly at an angle such as Wlll form with the curved end portion 18 of the rearwardly turned sections 14 and 15 a recess or indentation in which a conductor section may be received in such manner that pressure exerted against the conductor section will tend to lift the tongue member from its normal position and thereby permit the engaged conductor to slip into position between the outer faces of the rearwardly turned sections 14 and 15 and the inner surface of the tongue member 11. The

relation of connecter or clip to the conductor 19 is clearly shown in Figure 1 ofthe drawing and it will be seen that the conductor is securely grlpped between the tongue member 11 and the outer faces of the lateral strip sections 14 and 15.

The bridging member 13 which has already been referred to is so located with reference to the terminal portions of the strip sections 14 and 15 that the bridging member 13 underlies the upwardly bowed portion of the tongue member 11 beneath which the conductor section extends. In other words the bare conductor section rests immediately upon the bridging member 13 thereby adding to the effectiveness of the contact desired to be made between the connecter and the conductor.

In order to provide a suitable terminal on the connecter for attachment of the device to a battery or the like, the rearward end portion of the section 10 is bent at an angle as is clearly shown at 20 in Figures 1, 3 and 5 of the drawing. The angular terminal section 20 is provided with a tapered or converging formation as is clearly shown and an opening 21 is formed therethrough through'which a screw or other attaching member may be passed to secure the connecter in position.'

It will be seen that the connecter or clip isconnected by a high degree of simplicity in ill construction and a correspondingly low degree of wastage in the process of production. A minimum quantity of material is employed so that the cost of producing connecters of the type described isrelatively low With the result that the conneoters can be efiiciently produced. In addition to the low cost of production they are extremely eflective in operation in that they provide for the ready placing of the conductor section in gripped position in the clips without the necessity of making use of a tool of any nature in the attachment of the clip to or detachment from a conductor.

I claim 1. A connecter for electrical conductors comprising a strip having a tongue member formed along the median line thereof, the marginal portions of the strip extending toward the endof the tongue member and looped rearwardly to lie substantially in the plane of and in flanking relation to the tongue member.

2. A connecter for electrical conductors comprising a strip having a tongue member formed along the median line thereof, the marginal portions of the strip extending toward the end of the tongue member and looped rearwardly to lie substantially in the plane of and in flanking relation to the tongue member, and a bridging member for the marginal portions arranged to lie beneath the tongue member. i

3. A connecter for electrical conductors comprising a strip having a tongue member form'ed along'the median line thereof, the marginal portions of the strip extending toward the end of the tongue member and loopedrearwardly to lie substantially in the plane of and in flanking relation to the tongue member, a bridging member for the marginal portions, and said tongue member having an outwardly bowed central portion and an angularly outward extending terminal portion.

4. A connecter for electrical conductors comprising a-strip of metal having a tongue formed along the median line thereof, the

flanking marginal portions of the strip being curved into a loop formation with the free ends thereof J extending rearwardly along the lateral edges of the tongue member, and the free end of the tongue member being turned outwardly at an angle such that pressure of a conductor thereagainst will lift the tongue member and permit the conductor to slip into gripped relation between the inner face of the tonguev member and the outer faces of the flanking portions.

5. A connecter for electrical conductors comp ising a strip having a tongue member formed along the median line thereof, the marginal portions of the strip extending toward the end of the tongue member and looped rearwardly to lie substantially in the plane of and in flanking relation to the tongue member, a bridging member for the marginal portions arranged to lie beneath the tongue member, said tongue member having an angularly outward extending terminal portion, said tongue and said marginal portions having reinforcing grooves, and the.

other end portion of the strip being bent at an angle to the strip and provided with a screw-receiving opening.

6. A connecter for electrical conductors comprising a strip having a tongue member formed along the median line thereof and having an -upturned terminal lip, the marginal portions .of the strip being formed into loops which cooperate with the lip to form a normally open receiving notch.

7. A comlecter forelectrical conductors comprising a base portion, a part extending forwardly fromthe base portion and having its extremity bent outwardly, a second part extending forwardly from the base portion and having its end looped back toward the base portion and lying alongside of the firstnamed forwardly-extending part.

In testimony whereof I affix my signature.
