PLUG CONNEQTER.

Application filed March 23, 1923. Serial No. 627,070.

To all whom it may concern:

Be it known that I, LOUIS E. Islam, a citizen of the United States, residing at Verona, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Plug Connecters;

and I do hereby declare the following, when taken in connection with the accompanying drawings, and the characters of refer- 1 once marked thereon, to be a full, clear, and

exact description of the same, and which said drawings constitute part of this 'application, and represent in Fig. 1 a plan view, partly broken away,

of a plug connegter illustrating my invention.

Fig. 2 a plan view of one of the plug contacts detached, and shown on an enlarged scale.

Fig. 3 a side view of thesame.

Fig. 4 a sectional view on the line"4-4 of Fig. 3. p

This invention relates toimprovement in plug connecters, that is, devices for making electrical connection with flatirons, percolators, toasters, and other articles which are provided with two contact-pins over which the plug is placed. The object of this invention is to provide a lug with contactgripping-jaws, which wil readily yield to admit the contact-pins and make a close and perfect electrical contact therewith, and the invention consists in the construction as hereinafter described and particularly recited in the claim.

The plug 5 is of any approved form and design, accordin to the purpose for which it is to be use The plug contains two contact-members, each comprising what, for convenience, I will term a bottom-plate 6, adapted to be secured by a screw- 7 in a groove formed for it in the plug 5. This screw also forms a binding-post for one of the circuit wires. The central part 8 of 'this plate is transversely-bowed, and the outer end curved to form a lip 9. The plate is also formed on opposite sides with perforated ears 10, and near its forward end with downwardly-turned lugs 11. The

lip 9 the usual pins enter.

upper member 12 has its central portion 13 bowed, corresponding to the portion 8 of the bottom-plate, and is formed at its outer end with a lip 14, between which and the This top-plate is formed with perforated ears 15, corresponding to the perforated ears 10, and with lugs 16 corresponding to the lugs 11, and also with downwardly-projecting fingers 17, extending into notches 18 in the sides of the lower plate, so that the outer ends of the two plates are kept in align ment. Passing through the perforated ears 11 and 15, on each-side, is a bowed spring 19, the legs of which have inward bends 21 near their tips, which tips engage respectively with the lugs 11 and 16, the tendency of these springs being to hold the plates. close. together, and the bends 21, bearing upon the edges of the plates, maintain the parallelism, which may be further maintained by forming the upper plate with stops 20, which strike the forward ends of the cars 10. As before stated, the plugs are provided with two sets of my improved contacts and applied to the pins of electrical devices in the usual way for completing electrical connection therewith. These parts are readily formed and maintain their desired relative position.

I claim: 80 In an electrical attachment plug the combination with a chambered plug-body, of two socket members located therein, each comprising two independently-formed, parallel plates shaped to receive a plug axlally between them, and each formed near one end with a perforation and near its opposite end with an ear, and two bowed springs applied to the edges of the said plates by means of the said perforations and ears, located in planes at right angles to the planes of the plates, and coupling the same for their substant" lly parallel separation on the introduct-io of a plug between them. In testimony whereof I have signed this specification. I

LOUIS E. ISELE,
