ELECTRICAL GONNECTER Filed June 24. 1929 Patented July 11, 1933 UNHED STATES JOHANN Gr. PETERSON, OF WEST HARTFORD, CONNECTICUT ELECTRICAL Application filed June 24,

My invention relates to the class of devices that are employed for attachment to the end of a cable for connecting it to'another device or for connecting two lengths of a cable. and an object of my invention,

among others, is the production of a connectcr of this type that shall besimple 1n construction and particularly el'hcient 111 its method of operation.

One fornr of a connector. embodying my invention and in the construction and oporation of which the objects herein set out, as well as others, may be attained, is illustrated. in the accompanying drawin in U which Figure 1 is a side view of my improved connector.

Figure 2 is a side view looklng at the connector from a point at right angles to the point of view of Figure 1.

Figure 3 is a view in central lengthw1se section through the connecter.

Figure l is a view in central lengthwise section on a plane located at right angles to 5 the plane of the section of Figure 3.

Figure 5 is an isometric view of one section of a coupling conductor.

Figure 6 is a similar View of the other section of said conductor.

Figure 7 is an end view of the meeting ends of the socket members.

In the accompanying drawing the numeral 7 denotes one socket member of the coupling and 8 the other socket member of said coupling. These members are each preferably formed in two parts separated on a plane passing centrally lengthwise through the socket. The parts of each member are duplicates one of the other and a description of one, therefore, will suflice for both. Each of these parts 9 comprises a body 10 and a tip 11. When the two parts are omed the body is cylindrical in form as to 1ts outer surface and the tip is frustro-conical in shape and preferably larger in diameter atthe base then the diameter of the body 10.

Grooves 12 extend inwardly from the end of the bodv into a recess 13 in the tip of each part. these grooves being separated by an abutment 14: that is tapered at its end with- CON NECTER 1929. Serial No. 373,324.

in the recess 13, these edges converging into the recess.

Each member of a pair of coupling conductors is located in one of the grooves 12. These conductors are of cruciform shape, 55 each comprising a blade 15' and a head 16, the latter comprising the cross. The ends of this cross are adapted to project into cavities in the bottoms of the recesses 13, and binding screws 17 projectthrough holes in the heads and into binding screw cavities 18 in the tapered portion of the abutment 14;. The ends of the wires of a cable 19 are se cured to the heads 16 by the binding screws 17, and when the two parts of the member 7 are assembled and secured together as by a screw20, the blades 15 and cross parts of the head 16 will be located in the grooves and cavities in each of the parts, and the ends of the binding screws projecting into the cavities 18 securely and tightly fasten the conductors in place. It is observed that the ends of the wires of the cable 19, may be secured to the conductors before the latter are placed within the socket members, and this facilitates the method of assembling the parts.

The socket member 8, like the socket memher 7, is composed of two parts duplicates each of the other, and when joined, this member comprises a body 10 and a tip 11. Each part of the member 8 has blade recesses 21 with grooves 22 opening from said recesses to the end of the member. A cable recess 23 is formed in each part, the blade recess in each part opening into the cable recess 23. hen the two parts of the member 8 are joined, in the same way as the member 7, the grooves 22 will form holes entering a chamber comprising the recesses 21, the latter opening in to a chamber composed of the recesses 23.

Spring blades 24 are located in each of the recesses 21, their curved free ends being located in contact, or substantially in contact, with opposite edges ofthe abutment 14, and the spring action of the blades resisting movement thereof away from said abutment. The head 25 of each of these blades is of cruciform shape like that of the heads 16 of ment 1st, as hereinbc'lore described with respect to the other socket member. The wires of a cable 27 are secured to the spring blades by the binding screws 26, and when the two parts of the socket member 8 are secured together, as by a screw 28, the spring blades will be held tightly and securely in position, and, as hereinbet'ore remarked, the ends of the wires composing the cable 27 may be secured to the spring blades before the latter are placed in position.

If desired, a key 29 may be loosely inserted in one part of each socket member and pro jected into a recess in the other socket member. This key is or curved shape and resilient so that it will engage the recesses with a more or less binding action that will serve to retain it in position.

lVhile I have illustrated and described my invention herein as en'ibodied in socket memher, or socket members, for coupling or connecting the ends of an electrical cable, yet it will be apparent that the invention may be applied to electrical structures designed for other purposes and requiring the attachment thereto of the ends of wires for the purpose of conducting electricity to devices of various sorts.

In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, together with the device which I now consider to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative, and. that the invention may be carried out by other means and applied to uses other than those above set out.

I claim v v y 1. A socket member comprising two parts, each having complemental blade recesses and cable recessses, an abutment separating said blade recesses, said abutment having a tapered end forming shoulders converging toward their outer ends into said cable recess, blades located in said blade recesses and having bent ends resting against and supported by the tapered portions of said abutment, binding screws for securing wires to the bent ends of said blades, and means for securing said parts together to firmly retain said conducting members in place.

2. A socket member comprising two parts each having complemental blade recesses and a cable recess, an abutment separating said blade recesses, said abutment having a tapered end having shoulders converging toward their outer ends into said cable recesses, said tapered end having screw cavities, blades located in said blade recesses and having bent ends resting against and supported by the tapered portions of said abutments, binding screws for securing wires to the bent ends of said blades, the ends of said screws projectin into and closely fitting said cavities to secure the blades in place, and means for securing said parts together to firmly retain said conducting members in place.
