ELECTRIC-CONDUCTOR UNION.

SPECIFICATION forming part of Letters Patent No. 784,766, dated March 14, 1905.

Application filed August 1'7, 1903. Serial No. 169,676.

To (LZZ wit/fin it nut/y concern:

Be it known that I, FREDRIoK W. SORG, a citizen of the United States, and a resident of Englewood, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Electric-Conductor Unions, of which the following is a specification, taken in connection with the accompanying drawings, which form a part of the same.

This invention relates to electric-conductor unions such as are used for the purpose of connecting electric conductors, such as wires or cables, to form good electrical contact be tween them and to protect the point of juncture.

In the accompanying drawings, in which the same reference-numerals refer to the same parts in the several figures, Figure l is a perspective view showing an embodiment of my invention. Fig. 2 is an elevation showing this union as applied to join two conductors, and Fig. 3 is a cross-sectional view of the same.

The embodiment of this invention shown in the drawings is preferably formed of sheet metal of an electrically-conducting character, such as copper or brass. The union is shown as formed with a generally U-shaped section, the two free edges 1 and 2 being preferably of about equal length. A wire-retaining projection is preferably formed in the side of the union, so as to retain the wire in place therein. This projection may take the form of a continuous rib, if desired. As is indicated in Fig. 1, the internal wire-retaining rib 5 is formed in the side 3 of the union and also a similar rib is formed on the other side, a pocket adapted to receive and retain a wire being thereby formed at the bottom of the union. The free edges of the union are indicated as bent inward, so as to form a second wire-retaining pocket.

In operating this device the wires are brought together in the usual way and one of the wires, 7, is forced into the pocket of the union, the wire-retaining ribs serving to hold it in position, while the other wire, 6, is inserted into the union, preferably in contact with the first, the inwardly-bent edges of the union serving to retain this wire in position. The free edges 1 and 2 of the union are then bent down upon the wires on either end of the joint, and these ends being grasped by pliers are twisted into the-completed form indicated in Fig. 2. This twisting operates to force the edges of the union together throughout the whole length of the same, and these edges are tightly brought together upon the wires, forming practically a water-tight joint, and so firmly securing the two wires that the juncture has a greater strength than the wires themselves if properly formed.

It is of course understood that the term wire is intended to cover compound wire or cable or any other electrical conductor. Those familiar with this art may of course make many variations in the form, proportions, and number of parts of this device without departing from the spirit of this invention. I do not, therefore, desire to be limited to the disclosure which has been made in this case; but

What I claim as new, and what I desire to secure by Letters Patent, is set forth in the appended claims:

1. In electric unions, a U -shaped union having internal cooperating ribs to form a wire-retaining pocket in the bottom of the union, and being provided with substantially equally projecting edges on either side of said pocket, the free edges being bent inward to form a second wire-retaining pocket.

2. In electric unions, a union formed of U- sectioned sheet metal having internal projections to form a wire-retaining pocket, and having substantially equally projecting edges on either side of said pocket.

3. In electric unions, an elongated U-sectioned union having an open side through which wires may be inserted and having a depth suflicient to accommodate a plurality of wires side by side in the direction of its depth, said union having internallyprojectrib between its curved bottom and one of its ing means to retain a Wire therein. free edges to form a resilient Wire-retaining 4.
