ELECTRICAL CONN ECTER.

Application filed October 23, 1920. Serial No. 419,023.

' vision of a connecting member of simple and inexpensive construction and one which may be quickly and effectively attached to a binding post or other terminal member.

Heretofore, in order to make temporary connections, as to a storage battery terminal when charging, a clamping device has been employed which is made of two pivoted members having a spring interposed to give the required clasping tension. I provide an effective device of this character which is made in a single piece.

Some of the forms in which my connecter may be made are shown in the accompanying drawing, wherein Figure 1 is a View, in side elevation, of the preferred form of pay device in position on a binding post.

Fig. 2 is a: view looking from the left of Fig. 1; and

Fig. 3 is a bottom plan view;

My device is intended, primarily, for use with battery-charging outfits, and I have illustrated it as connecting a battery terminal or binding post 13 to a conductor cable 14 leading from a source of supply. The connecter consists of a strip of spring material 15, stamped out of a sheet of phosphor bronze or other conducting material, and is preferably bent to the form shown in Figs. 1, 2 and 3. It will be observed that it is of a substantially inverted U-shape, with an extension 16 which serves both as a handle and as a support for the cable 14. Inturned ends 17 and 18 are provided to grip the terminal 13. The inturned ends have sharpened portions to enable them to more eflectively grip the terminal member 13.

The cable 14 may either be soldered in the extension 16 or it may be inserted in a brass tube 19 and the tube pressed tigh ly there- 'about and then soldered in the extension 16.

To remove the connecter 15from the binding post 13. the extension 16 is drawn outwardly to disengage the inturned end 18 and the extended portion 16 is then'raised until the inturned end 18 is carried across the top of the binding post. To place the connecter 15 on the binding post, the inturned end 17 is hooked upon the binding post, and a pull exerted on the extension 16 to permit the swinging of the inturned end 18 down into position opposite the end 17.

The use of the tubular member 19, and also of solder, may be dispensed with and the end of the cable 14- be inserted in the cable-supporting loop which is provided in the connecter 15, and the lodp squeezed or flattened to hold the cable tightly in place.

From the foregoing, it will be seen that I provide a one-piece connecter member of simple and compact form which may be readily applied or removed by the use of one hand only.

It is obvious that various modifications of structure might be made without depart: ing from the spirit of the invention as set forth in the appended claim.

I claim as my invention A connecter comprising a unitary flexible metallic strip of substantially inverted U- shape having two legs provided with inwardlycut end portions in substantially the same plane to constitute oppositely disposed cooperating contact jaws for yieldingly gripping a terminal, one of'the said jawsbeing of greater length than the other and constituting one portion of a flat loop extending at right angles to one leg of the strip which constitutes a combined handle and socket for receiving a permanently attached conductor.

' In testimony whereof, I have hereunto subscribed my name this 13th day of October 1920.

EDGAR w. BREISCH,
