CONNECTOR FOR ELECTRIC WIRES.

Specification of Letters Patent.

Patented Sept. 25, 1917.

Application filed May 6, 1916. Serial No. 95,907.

To all whom it may con ern:

Be it known that I, ALEXANDER B. S1MP- son, a citizen of the United States, and residing at Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Connectors for Electric Wires, of which the following is a specification.

My invention consists of an improvement in connectors used for joining the ends of electrical wires together so as to make electrical connection between them.

In connecting electrical wires, considerable space and time can be saved by clamping the strai ht ends of the wires directly under the nut and head of the binding screw, through the medium of a folded strip of metal, and my object is to produce a very light weight and very small clamp connector which will hold the wires in good electrical connection.

My invention consists in combining with a threaded binding screw and nut, a folded strip of conducting metal or material interposed between the nut and the head of the binding screw, in the loops formed by the folds of which strip, the ends of the wires are inserted, so that when the nut is screwed up tight, the loops of the folds although alined under the nut and head of the binding screw, will not be crushed by the clamping process. To preserve the shape of the loops the metal of the loops is removed from under the nut and screw head.

In order that my invention may be fully understood I shall describe in detail the mode in which the invention is carried into practice and then distinctly claim the invention.

Reference is to be had to the accompanying drawings forming part of this specification in which like parts are designated by the same numerals in all the figures.

This invention is an improvement on the connectors for which a Patent No. 1090888 was issued to me dated March 24, 1914.

Figure 1 is 'a view of a connector embodying my invention joining six wires. Fig. 2 is another view of the same connector without the wires. Fig. 3 is a view of the reverse side of the same connector. Fig. 4 is a View of a modified form of my connector designed to join two or three wires. Fig. 5 is a view of the metal strip used in the connector shown in Figs. 1, 2, and. 3,

before the strip is folded. Fig. 6 is a view of the binding screw and nut.

In Fig. 1 the wires as shown are insulated and are designated as number 10. The connector as shown in Figs. 1, 2, and 3 consists of a flexible strip 13, shown in Fig. 5, of brass, tin or other preferably soft metal, folded upon itself in this instance four times reversely to form the folds 14, 15, 16, and 17. Through the folds 14, 15, 16, and 17, are passed two threaded binding screws 18 and 19, on the threaded end of which are the corresponding binding nuts and 21, so that the folds are confined between the nuts and the heads of the binding screws. In the loops 22, 23 and 24, the openings 25, 26, 27, 28, 29, and are made in the part of the loops under the nut and screw head, corresponding to the size of the nut and screw head, so as to allow the nut and screw head to clamp the folds 14, 15, and 16 and 17 without materially crushing the loops.

The ends of the several wires to be connected are inserted in the loops 22, 23, and

24, as shown for example in Fig. 1, with the respective ends of each pair butting each other in the respective loops at the central point of the loop; the nuts 20 and 21 are then screwed up tightly against the outer fold 17, so as to securely bind the wires as shown, between the nut, the folds 15 and 16 and the screw head, on one side of the connector and between the folds 14 and 17 on the other side of the connector. It is evident that two wires can be connected together by inserting the ends of the wires in different loops, for example in loops 22 and 23, and by screwing up the nut 21 the two wires will be clamped together, though the wires differ in size and characteristics; and additional wires as required may be inserted in the remaining loops, up to a total of six wires.

In the modification shown in Fig. 4, the connector has only one binding screw, thus accommodating two or three wires, or half the capacity of the double screw connector, and is in fact half of the connector shown in Fig. 2.

I claim as my invention:

A connector consisting of a strip of pliable metal bent into four folds, forming loops at the bends, alincd post holes for eachbinding post in the opposite folds, threaded binding posts through said alined holes, and having a head on one end and a nut screwed on the other end respectively h'ear- SIMPSON, have signed my name to this speciing against the outer folds, the loops having fication in the presence of two subscribing 10 beeln fcut away1 from under tlhe screivlhead Witnesses, this fourth clay of May, 1916. {111C rom unc er the nut tie nuts oeing 5 screwed upon the binding: screw to clamp ALEXAL DER SIMPSON' and connect the Wires Without materially Witnesses: altering the shape of the loops.
