UNITED STATES JOSEPH H. BBEAZNELL, OF BROOKLYN, NEW YORK.

TERMINAL-CLIP CON NECTER.

Application filed July 27, 1922. Serial No. 577,856

To all whom it may concern:

Be it known that I, JosnrH H. BnEAzNnLL. a citizen of the United States, residing in the city of New York, borough of Brooklyn, in the county and State of New York, have invented a certain new and useful Improvement in Terminal-Clip Connecters, of which the following is a specification.

The invention relates to clips for connecting wire terminals to the posts of s arkplugs and the like, and the object o the invention is to provide a simple, economically manufactured spring clip by which the wire may be easily and quickly attached to and detached from the post, and which in the attachedcondition will hold reliably and maintain the desired electrical contact efficiently.

The invention consists in certain novel features and details of construction by which the above objects are attained, to be hereinafter described and claimed.

The accompanying drawings form a part of this specification and show the invention as it has been carried out in practice.

Figure 1 is a side elevation of a referred form of the improved clip attac ed to a sparkplug. 4

Figure 2 is corresponding plan view.

Figure 3 is a section taken longitudinally of the clip between its jaws, on the line 3-3 in Figure 2.

Figure 4 is a rear elevation corresponding to Figure 3.

. Figure 5 is a section on an enlarged scale, taken through the jaws of the clip and the inclosed post.

Referring to Figures 1 to 4 inclusive, 10 is the screwthreaded post of which the terminal wire 11 is to be attached, shown as art of a sparkplug 12 but which may be a inding-post or any like screwthreaded member.

The clip is shown as'formed in a single piece from sheet metal, preferably spring brass, stamped and shaped by suitable dies to the form shown. It comprises an open cylindrical body 13 having spring jaws 14 extending side by side therefrom, each formed with a semicylindrical bend 15, which bends are arranged oppositely to produce an open socket between them 1n which the post 10 is grasped and inclosed. The jaws extend beyond the bends and are curved outwardly and oppositely as at 16 to .taut tobring the insulated facilitate engagement with the post by for- Clbly spreading and guiding'the jaws in the operation of applying'the clip.

An important feature of the invention resides in the means for insuring reliable engagement of the jaws 14 with the post. This is effected by tapping or otherwise producing internal screwt ireads in the bends the post and resist effectually any strains tendingto move the clip axially of the post while permitting the clip to rotate or oscillate thereon to an extent required by the relative position 0 the terminal wire to the post. From the up er edge of the closed rear side ct the b0 y 13 extends a branch 17 having oppositel extended curved wings 18 adapted to be cut around the insulated terminal of the wire 11 and partially inclose itin a firm grip. On the rear face of the body 13 is formed an internal groove 19, and near the upper edge isan opening 20 in axial alinement with the terminal wire, and at the rear lower edge of the body is a notch 21.

.The Wire 11 is attached to the clip by removing a short section of the insulation to exposea length of the core-wires which are then threaded through the opening 20 to the inner face of the body 13 and drawn portion within the wings 18 which are then bent closely thereupon; the core wires are drawn tightly through the notch 21 and lie partially in the groove 19 and are then bent/sharply back to lie below the wings. Thus attached the engagement is reliable and electric contact insured. A drop of solder may be applied to the core wires in the groove or at any convenient point if desired.

Although the spring jaws are described as tapped to match the standard. threads of the post and to be applied to the latter in place of the usual nut, it will be understoodthat the post may be specially formed with a series of annular grooves and the jaws correspondingly formed to match thereto; the screwthreads of the post and jaws perform no function other than a means of engagement by which movement of the jaws Q longitudinallzeof the post is tgrevented, and l being formed with an internal groove, and
