UNITED STATES PATENT OFFICE.

ALVIN E. BUCHENBERG, F TOLEDO, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE ELECTRIC AUTO-LITE COMPANY, OF TOLEDO, OHIO, A CORPORATION OF OHIO.

CONN EGTER.

Application led September 9, 1918, Serial No. 253,262. Renewed April 29, Y1926.Y

This invention relates to improvements r in connecters for wire terminals.

An object of the invention is to provide :l connecter which is particularly adapted c for terminals of wires used as electrical conductors.

Another object of the invention is to provide such a connecter, whereby a neat and strong connection can be expeditiously made 1U with the terminal of a wire.

Yet another object of the invention is to provide a connecter as above characterized, which, when connected to a wire, obviates any possibility of the same becoming disconnected.

Further objects of this invention relate to economies of manufacture. and details of construction as will hereinafter appear from4 the detailed description to follow. I accomplish the objects of my invention in one instance by the devices and means described in the following specification, but it is evident that the same may be varied widely wit-hout departing from the scope of the invention as pointed out in the appended claims. yA structure constituting one einbodiment of my invention, which may be the preferred, is illustrated in the accompanying drawings forming a part thereof, 3o in which:

Figure I is a plan view of a stamped blank shown in side elevation and constituting the initial form of the connecter.

Figure II `is a view similar to Figure I and shows the wire holding portion of the connecter, formed for the insertion of a wire.

Figures III and IV are views similar to Figure II and illustrate the preferred manner of connecting the connecter with the terminal of a wire.

' Figure V is a transverse section on the line V--V of Figure IV, and

Figure VI is a perspective View of the connecter as shown in plan in Figure II.

Referring to the drawings, a plate or blank 10 is provided, comprising a holding portion 11 and a connecting portion 12 (Figure I). A central opening v13 is provided in the connecting portion 12, adapted to receive the screw post or other means to which this portion of the connecter is to be secured. The portion 12 is approximately circular in shape, and, with respect to the length L the strands are spread and of the connecter, has its sides cut away as indicated at 14 and 15. The connecting portion 12 is iurther provided with radial grooves which are stamped in the bottom ace ofthe portion and thus providing ,the raised surfaces 16 on its upper face. The advantages of these raised surfaces 16 are well known in the art and a statement relative thereto is unnecessary.

In the portion 11 of the blank or plate l0 there are dicated by the lines 17 and 18, whereby wing sections 19 and 20 are provided. This is preferably done by stamping.

The wing sections 19 and 2O will be hereafter referred to as inner wings and the portions between the longitudinal edges and the dotted lines 21 and 22 of the connecting portion 12 will be referred to as the outer wings 23 and 24, respectively. In Figure II, I have shown the inner wings 19 and 2O bent inwardly," so that their longitudinal edges are dispoed in spaced relation for receiving a ure between them. Also, the outer wings provided slit-like openings, in-

23 and 24 are bent inwardly to correspond to a plane substantially perpendicular to the connecting plate portion 12, as clearly illustrated in Figure VI.

When it is desired to secure the'connecter to the terminal of the wire, the insulation is .removed from the terminal which is then inserted between the inner wings to the connecter and the said wings are then bent downwardly upon the wire, as illustrated in Figure III. The wire 25 in this particular instance is of the flexible type, comprising a plurality of strands. It is to be understood, however, that a single strand wire may be used equallyas well. As shown in Figure V, flattened so that a greater area of contact is had between the wires and holding portion 11 of the connecter, whereby the r-esistance to How of current is lessened, and the possibility of heating eliminated. This may be taken'advantage of in 'dispensing with the use of solder and obouter Wings are then clamped down on the Wire thus completing a close contacting and secure grip between the connecter and` Wire.

In the above description and the accompanying drawings, I have described and shown my invention when used as a connecter-for terminals of electrical conductors. It is to be understood however, that my invention is applica-ble to other uses with `equal efficiency, and is not to be limited, as herein shown and described.

Having thus described my invention,

what I claim'as new and desire to secure byv Letters Patent, is:

l. A terminal for an electric conductor comprising a plate having a pair of integral wings adapted to be folded over fromv opposite sides in one direction to bind said conductor against said platefand a second pair of integral wings adapted to be similarly folded over to bind another part of said conductor against said first mentioned Wings.

2. A terminal forf an electric conductor comprising an apertured portion and a. conductor engaging portion, said latter portion having an inner pair of oppositely positioned wings adapted` to be folded in one direction to engage one part of said conductor and' having an outer pair of oppositely positioned wings adapted to be `folded in the same direction to engage another part of said conductor to bind it against the outer faces of said first mentioned pair of Wings. 3. A terminal for an electric conductor l comprising' a metallic plate having a binding post attaching portion and a conductor atpart of said conductor against said second.

Wings.

4. A terminal for an insulated conductor having `a bared end portion comprising a plate having Wings extending laterally from opposite sides thereof, each of said Wings having a second Wing punched from the body thereof, said second Wings being fold- -edrto clamp the bared end of said conductor against said plate and said first Wings being folded to clamp an insulated portion of said conductor against said .second Wings.

In testimony whereof, I affix' my signature.
