ELECTRIC COUPLING.
Specification of Letters Patent.
Patented Oct. 17, 1905.
Application filed October 26, 1903. Serial No. 178,460.
, 1?) all whom it may concern:
Be it known that 1, NORMAN MARSHALL, of Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Electric Couplings, of which the following is a specification.
My invention relates to improvements in electric couplings designed to make temporary connection or taps to permanent circuits,
which are commonly known as plugs, and receptacles, and more especially to the receptacle for such a coupling.
The object of the invention is to provide a simple and compact construction of receptacle and face-plate which shall provide for the convenient and ready insertion of the contactrods of the cooperating plug or cap without danger of bringing such rods into connection with the face-plate either in inserting or removing the connection.
To this end theinvention consists in features andcombinations hereinafter described, and referred to in the claims.
In the accompanying drawings, in which a receptacle embodying the present invention and its cooperating plug are shown, Figure 1 represents a plan view of the receptacle with the plug removed; Fig. 2, a vertical section showing the plug introduced into the receptacle to-make the temporary connection, and Fig. 3 is a bottom plan View of the plug.
As indicated in the drawings, the receptacle comprises a metallic face-plate A, to which is secured a body B, of insulating material such, for instance, as porcelain. The porcelain body B is provided with recesses in which are mounted the metallic sleeves C, which form contact-sockets for cooperating with the contact-rods of the plug in making an electrical connection. The sleeves C are provided with shoulders c, which engage the upper side of flanges 5, projecting into the recesses in the body B. The sleeves are held in position in the body by means of nuts cl, screwed onto the lower ends of the sleeves and engaging the under side of the flanges b. The sleeves are provided with recesses 0, extending upward from their lower ends for receiving the wires of the electric circuit, which are connected with the sleeves by means of bindingscrews f, extending through the sleeves into the recesses e. The body B is provided with slots g, through which the binding-screws may pass in 1nsert1ng and removing the metallic sleeves, and the body is also provided with recesses it in its outer surface within which the heads of the screws lie. This construc tion and arrangement forms a simple and eflicient metallic contact-socket within the insulating-body of the receptacle; but it will be understood that this particular form of contact-socket is not essential and that various forms of contact-sockets might be used without departing from the invention.
The face-plate A is provided with two bushings D, arranged over the recesses in the body B and provided with holes D, which register with the holes in the sleeves G for receiving the contact-rods of the plug. The recesses in the face-plate. in which the bushings D are mounted, are undercut toward the under side of the face-plate, and the bushings are provided with projecting flanges D which enter these undercut portions, and thereby permanently secure the bushings in place. As will be observed, the bushings are further secured in their holes by the insulating-bod y B, the upper end of which overlaps the outer edges of the bushings, thus permanently securing the bushings in place and in a measure forming a support or backing for them, which will prevent their accidental dislodgment.
The plug or cap for cooperating with the receptacle in making-an electric connection consists of an insulating-body E, in which are mounted the two metallic rods F, formed and arranged to fit within the holes in the sleeves (J. The plug E is provided with holes G, which extend from the upper end of the body to recesses H, formed in the under side of the body. The wires of the electric circuit are passed through these holes G and are connected with the contact-rods F by nuts I screwthreaded on the rods.
When an electrical connection is to be made, the rods F are thrust through the bushings D and enter the contact-sleeves C, thus electrically connecting the wires which are connected with the sleeves and rods. By reason of the bushings D the rods F may be quickly and conveniently thrust through the faceas guides to direct the rods F into the contact-sockets of the receptacle, and thus facilitate the making of the coupling.
What I claim, and desire to secure by Letters Patent, is
1. A receptacle for temporary electrical couplings consisting of a metallic face-plate, a body of insulating material secured thereto, two metallic sleeves secured in parallel recesses in said body, holes in the face-plate over said recesses, insulating-bushings in said holes provided with holesregistering with the holes in the sleeves, and projecting flanges on the bushings lying between the end of the insulating-body and the face-plate, substantially as described.
2. A receptacle for temporary electrical,
couplings consisting of a metallic face-plate,
a body of insulating material Secured against one side of the same, metallic contact-pieces secured in said body, bushings of insulating material secured in the face-plate and provided with holes registering with the contactpieces, through which holes the metallic contacts of the cooperating plug are to be inserted in making a connection, said bushings being held securely in their holes in the faceplate by having their edges overlapped by the part of the body of insulating material bearing against the face-plate.
In testimony whereof I have aflixed my signature in presence of two witnesses.
