FABNUHT F. DORSEY, OF ROCHESTER, NEW YORK, ASSIGNOR TO NORTH EAST ELECTRIC COMPANY, OF ROCHESTER, NEW YORK, A CORPORATION OF NEW YORK.

ELECTRIC CONNECTION.

To all whom it may concern:

Be it known that I, FARNUM F. Donsnr, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New Yo have invented certain new and useful improvements in'Electric Connections; and-I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Which it appertains to make and use the same.

tremity of the conductor 5.

This invention relates to anelectric connect-ion of the type in which a flexible con ductor or cable 15 removably attached to an electric terminal, in the form of a socket, by means of a plug-member secured to the end of the flexible conductor.

The object of the invention isto produce an electric connection, of the type in question, which shall be simple and inexpensive in construction, and more particularly one in which the pluganember may be made'entirely of sheet-metal, in a single integral piece, of a form adapted to be readily and securely attached to the conductor.

To the foregoing ends the invention resides particularly in the form of the plugmember hereinafter describech and in the manner in which this plug-member is attached to the flexible conductor.

In the accompanying drawings Figure l is a side-elevation of a plug-and-socket connection embodying the present invention, with the socket-member shown in section. Fig. 2 is a. side-elevation of the flexible conductor and the plug-member fronra point of view opposite to that of Fig. 1; and Fig. 3 is an end-elevation of the plugmember.

The invention is illustrated as embodied in a plug-and-socket connection suitable for use with electric ignition-apparatus, i0ugh the invention is obviously applicable to various other uses. The flexible conductor is in the form of a cable 5, provided with a sheath 6 of insulating material. The plugmember comprises a sheet-metal sleeve 7, which is clasped around the insulation 6 at some distance above the extremity of the conductor. From the sleeve 7 three integral arms depend. The arm 8 is bent at a rightangle. at its lower end, to provide a part 9 which is perforated to receive the lower ex- This conductor secured to the part 9 by separating the ends of its constituent wires and securing them in place by means Specification of Letters Patent.

der 10. I

- Theother two arms 11 are bent inwardly outwardly, as shown in Fig. 2, constitute spring-arms adapted to press outwardly against the walls of the socket-member and thus to insure a good electric connection, while at the same time acting to retain the plug-member in the socket. In order that the connection may be more secure, the socket-member or terminal 14 is provided with an annular counter-bore 15 which is engaged by the projections 13, as shown in Fig. 1. By this arrangement the parts are securely held together, though they may be disengaged by a strong pull on the conductor. The socketan'ember 14 is shown as embedded in a sleeve 16 of insulating material, but this is not an essential feature of the invention. I

A valuable feature of the invention resides in the fact that the projections 13 are located near the extremity of the conductor, thus permitting the conductive insert 14 in the socket-member to be made comparatively short and inexpensive. It should also be noted that the resilience of the sleeve 7 is added to that of the arms 8 and 11,.owing to the fact that the sleeve is divided, so that the arms can be made comparatively short of adrop of solwhile securing the necessary degree of ela'sductor; and a plug-member adapted to cooperate with said socket-member, the plugnicmbcr consisting of an integral sheet-metal piece comprising a divided sleeve clasped around the insulation of the conductor, and a plurality of arms extending, from the edge of the sleeve. in the direction of the extremity of the conductor, one of said arms a being attached to the extremity of the conductor and one or more of the arms springing outwardly for resilient engagement with the socket-member. y

2. An electric connection comprising: a socket-member with an internal recess; an insulated flexible conductor; and a plugmember adapted to' cooperate with said socket-member, the plug-member consisting .of an integral sheet-metal piece comprising I a divided sleeve clasped around the insulation of the conductor at a point remote from the extremity thereof, and a plurality of substantially parallel resilient arms extending, from the edgeof the sleeve, to the extremity of the insulation, the extremity of one of the arms being bent inwardly, and

member.

attached to the extremity of the conduetor, and one of the arms being provided, near its free extremity, with an outward projection for engagement w-iththe recess in the socket- A plug-member comprising a divided sheet-metal sleeve, and a plurality of substantially parallel resilient arms extending FARNUM F.
