This invention relates to devices for uniting the meeting ends of pliable wires in a manirier to constitute a joint of maximum strength and firmness.`

Such joints are commonly made by twisting the exposed, parallel extending ends of the wires by liers or like implements, whereby the stran s are strained in the production or a coil, frequently lacking in regularity and symmetry, the operation involving considerv able expenditure of energy and previous exinvention to provide a device whereby the ends of the wires may be firmly united by being twisted in a particularly easy and convenient manner.

A further feature is in the provision of means combined' with the twisting elements that completely encloses and confines the coiled wires and which maybe filled with solder or a melted metallic substance whereby complete conductivity of current is secured.

Another advantageous aim is to provide such devices-in a variety of sim le forms, all of inexpensive construction an easy of application.

These objects are accomplished by the novel construction and arran ement of parts in a practical manner as herelnater described and shown in the accompan ing drawing, forming a material part of t is disclosure, and in which l l Figure 1 is a longitudinal sectional view of a preferred form of the connector, showing t e wires as entered therein preliminary to twisting the same.

Figure 2 is a similar view of the same parts as they appear after the twisting operation. Figure 8 is an end view of the same.

4 is a side elevational view of l vment by which modied form of the device partially broken away to show the interior construction.

In Figures 1 to 3 the device is shown to v consist of a pair of duplicate heads 10 and olygonal cross section each bein adapted) g to receive a wrenchor like implethey may be individually rotated or held. Extending integrally from the base of each head are conic frustums 12 and 13, their co larger diameters being disposed outwardly,

v away from the heads.

I Formed. longitudinally in each head and cone are twin apertures ane 15 arranged 1n parallel equidistant from the center and @5 spaced to present a soli-d wail of there between. A tube 1K3, approximating the short diameter of the an opening to pass over the enla the conical extensions, er i conically contracted, by spinning or analogous means, to fit over lthe extensions 12-13, the ends of the tube abutting the should e 'fi the heads 10-11 and acting; to connes n in if@ a manner to prevent movement in ene onection of their length but permit each cone to turn freely therein.

One of the wires 18 is passed through the `aperture 14 in the head 11 to extend within 8G the tube 16 and out through the corresponding aperture in the head 10 to reach slightly beyond; the other wire 19 is entered through the opening 15 in the head 10, extended through the tube and corresponding opening in the head 11, as best seen in Figure 1.

After thewires have been thus ositioned as indicated, twisting is accomplis ed in an obvious manner by holding one of the heads and rotating the other, or by turning the heads in opposite directions, lthereby producing 2a tightly wound coil 20 as seen in Figure I The length of the tube 16 may be proportioned to the diameter of the wires to be connected and, as will be seen, provides a guard for the coil which may fill its interior tube lled with solder 22 or the like, comletthejunctionbetweenthewimwhich, 1f previously cleaned, as great conductivi as would the same wire without a joint.

'In the form shown in Fi heads 25 of the same genera nature are provided with cylindrical extensions 26 containingY annular recesses 27' and are drilled to receive the wires 18-19 as described.

A tube 28 receives the extensions at its ends and is rolled or otherwise treated to produce in reaching beads 29 en aging the recesses 27 to be held rotatably in geace.

A cut out 3G in the tu wall provides means for the entry of solder 31 if desired, the device being otherwise in all respects as that previou'sly described.

While certain preferred embodiments of i this device have beenshown and described, it

will be understood that changes in the form,

arrangements, proportions, sizes and details thereof may be made without departing'from the scope of the invention as defined in the appended claims.

Having thus described my invention, what l claim as new and desire to secure by Letters Eatent, is 4 l. in a wire connector having a tubular element through which a pair of wires to be twisted may extend, a head having a pair of Egrforations to receive the ends of wires to 'connecteds and an integral frusto-conical 'extension on said head extending within the tubular element and swivelly connected therewith.

2. A wire connector comprising a pair of heads, each head having perforations to receive the wires to be connected, a tube disposed between said heads and through which the wires extend, and integral portions on said heads extending within the tube and reely rotatable in either direction in the tube to twist the wires within the tube.

3. A. wire connector comprising a tubular element for the reception of wires to be twisted, a head having perforations to receive the wires, and a portion' extending from said head into the tube and freely rotatable in Aeither direction therein to twist the wires.

4. A wire connector comprising a tubular element for the reception of wires to be twisted, a head having perfor-ations to receive the wires, and means for swivelly connecting -the head with the tubular element.

This specification signed and witnessed this 20th day of May, 1927.
