ELECTRICAL CONNECTER.

Application led February 10, 1923,Seria1 No.` 618,424. Renewed December 27, 1.928.

This invention relates to electrical connecters, such as may be used for connecting a plurality of circuits to one source of supply.

It is often desirable to connect a plurality of electriccircuits to one source of supply and such supply being an ordinary house lighting circuit. A typical instance of such a case is that of Christmas tree l1ghting. In this class of lighting, the lamps are ordinarily connected in series in strings of eight, more or less. As this number of lamps is sometimes insuticient for larger size This invention has among its objects,v

therefore, to provide a connecter which may be connected with the supply and which provides releasable connections in the form of plug sockets by means of which the various circuits may be connected. This invention also provides a connecter which may be connected to a given circuit intermediate its len h without cutting the wires thereof.

Ilurther objects will appear from the detail description taken in connection with the accompanying drawing, in which:

Figure 1 represents a connecter embodying this invention; and

Figure 2 is a view of the connecter of Figure 1 with one of the halves removed so as to disclose the interior connections.

ReferringV to the accompanying drawing, the, connecter comprises an insulating body made in two connectible half parts 1 which may be practically duplicates of each other and arranged to fit together face to face.

Each of these parts is provided with recesses 2 longitudinally thereof and end anges 3 A adapted to provide abutments for the plugs.

Arranged transversely of the recesses 2 is apair of openings 4, each provided with a surrounding-boss 5. These openings provide an inlet for the supply circuit and a channel connecting the same with an outlet for an extension thereof. The connection trees, it is desirable to provide for con-y necting in two or more of such strings of may thus be attached at any intermediate portion of a flexible cord.

Arranged within the recesses2 is a pair of metallic contacts G, cach provided With an end portion bent back upon the connecter so as to provide a spring clip located just within the end opening of the recess 2. Each connecter 6 is provided near the middle thereof with a lip 8 provided with a socket fora clamping screw 9, by means ot' which the wires l() of the supply circuit may be connected to the contacts 6 as illustrated in Figure 2. Itwill be noted that such connection may be made at any point in. the

length of the wire by simply stripping appropriate portions of the two wires and making connections by means of the screws 9 as illustrated. The screws 9 being displaced relatively provides that the stripped portions of the wires l0 do not come opposite each other but each stripped portion lies opposite an insulated portion of the adjacent wire. This insures'adequate insulation between the wires at all points. After connecting the wires, the two half portions may be placed one upon the other so as to cover the connections and the contacts 6 and may then be secured in assembled relation by means of. screws 11' or other suitable fasteners. f

The branch circuits 13 which are to be connected to the supply circuit may each be provided with a plug 12 provided with a pair of blades 14 adapted to enter the recesses 2 and contact with the clips 7. The clips 7 by their spring action hold the plugs in place in the socket.

It will be noted that `this invention provides convenient'and durable means for connecting a series ofcircuits to a single supply. l/Vith such a connector in use, each of the separate branch circuits may be .handled individually in arranging the same as in the case of the Christmas tree lights above mentioned, so as to avoid entangling the various circuits wlth each other and other awkwardness in handling the same. Each circuit -may' be arranged individually and thereafter invention is not to be limited to the specific details shown and described.

Having thus described the invention, what is claimed is: v v

l. A plural socket connecter for attachment to the Wires of a continuous flexible cord, comprising, a body having a socket at each end thereof and having a channel extending therethrough transversely of said sockets adapted to receive the traversing Wires, and terminal connections within said body and'adapted for attachment to the wires and provided 'with contacts adapted for engagement by plugs inserted in said sockets.

2. A plural socketconnecter for attachment to the Wires of a continuous lexible cord, comprising, a body having a socket at Aeach end thereof and havinga channel extending therethrough transversely of said sockets, said body being adapted for placement over an intermediate portion of the cord with the wires thereof Within and traversing said channel, and terminal connections within said body and adapted for attachment to the Wires and provided With. contacts adapted for engagement by plugsy ing a channel extending therethrough transversely of said sockets in order to receive the traversing Wires, and terminal connections Within said bodyI and adapted for attachment to the wires and provided withl contacts adapted for engagement by plugs inserted in said sockets.

4. A plural socket connecter for attachment to the Wires of a continuous ieXible cord, comprising, a body composed of two connectible halves having channels there- .along terminating in socketsl at the ends thereof, conductors extending along said channels and provided at the ends thereof with contacts within said sockets, said body having a channel intermediate its endsv and traversing said first channels, and terminal binding posts on said conductors androntiguous said second channel.

A plural socket connecter for attachment to the Wires of avcontinuous-flexible 1 cord, comprising, an elongated body, di-

vided longitudinally thereof, provided withl ERNEST ALSCHULER.
