ELECTRICAL APPLIANCE.

Application filed August 25, 1924. Serial No. 734,008.

This invention relates to an improved device which may be broadly referred to as an electrical appliance. The invention however has more specific reference to an appliance of this class which is in the form of a plug adapted to be tapped into a wall socket, the .plug itself-provided with a plurality of sockets one to receive a line wire plug, one for a light bulb and the remaining one being especially designed for reception of an auxiliary low current capacity fuse.

The improved device has been designed with an aim to obviate the necessity of going to the fuse box in the cellar to replace a main high current-capacity .fuse until the auxiliary has blown.

The primary object is to provide a single body which is provided with a pluralit of socketed branches, there being'a socket or a light bulb, a socket for a cord plug, such as is used with an-electric iron or the like, and a socketfor the auxiliary fuse. The cord plug socket is in electrical connection withthe auxiliar fuse, the light bulb socket which is placed in the socket 4 will be lighted being entirely lndependent and unfused, whereby it may be readily ascertained whether the fuse blown by an overload is the auxiliary fuse in the appliance, or a main fuse in the supply line.

In the accompanying drawing y The single figure represents a. sectional view partly in elevation, of an electrical appliance constructed in accordance with the present invention.

In carrying out the invention I provide a body which is constructedof suitable insulation material, the body being generally designated by the reference character 1. It is.

preferably hollowed out at its center and is provided at one end with a plug 2 adapted to be screwed into a wall socket fixture or the like. In alignment with this plug and at its opposite end it is provided with a branch 3 which in turn is provided with a socket 4 for reception of a bulb. The body also includes the laterally directed'branch 5 provided with a socket 6 for a plug from an electric iron, curling iron, or other similar article. The sockets are equipped with a shell or lining of electroconductive material 7 forming one of the contacts. They are also provided with suitable centrally located spring contacts 8. Disposed on the opposite side of the body and extending at right an les therefrom is the somewhat larger branch 9 formed with a socket for accommodating a conventional type of fuse 10. The outer end of this branch is externally screw threaded to permit a screw cap 11 to be screwed thereon. The cap is provided with central apertures'for permitting passage of air therethrough for cooling the fuse. The fuse socket is also equipped with a lining and contact as is the aforesaid plug 2 and a plurality of wires supply the current. A pair of wires 12 and 12 supply current directly to the socket 4, while a separate pair ofv wires 13 and 13 supply current to socket 6. Itwill be noted that wire 13 connects with wire 12, while wire 13 leads to the center contact of the fuse socket. Moreover, the shell of the fuse socket has electrical connection with wire 12*. Under this arrangement, socket 6 is-fused by the' auxiliary fuse 10. ()n the other hand, socket 4 is independent and is only fusedby the higher current capacity fuses contained in the main supply line of the cellar or the like. It will thus be seen that when the plug 2 is tapped into the wall socket, the electric bulb directly from the main supply wires. This will also be true of the cord plug, which is fitted into socket 6, but this socket is fused through the auxiliary fuse 10. Hence, in case of an overload of current, the low cur rent fuse 10 will be blown, for ofcourse it isv possible that one of the higher current capacity main fuses would be blown. This may be readily ascertained, however, by the appliance, as constructed. For instance, if the fuse 10 has blown and the lamp bulb in the socket 4 is still illuminated, then that shows that the fuses in the'main supply line are still good, it being only necessary to replace the auxiliary fuse 10. ,Obviously, by having the appliance in the same room with the electrical contrivance bein used, advantageous results will be obtaine l'Vhile I have shown and described the specific embodiment of the invention it is to be understood that minor changes comin Within the field of invention may be resortec l to if desired.

. Having thus described the invention, what I claimis:- Y

1. An electrical appliance comprising a single body of insulation material including a plug adapted to be tapped into a wall socket, and a plurality of branches having sockets formed therein, the internal walls of such sockets being lined with electroconductive material, each socket being pro vided with a central contact, and one socket being provided with external screw threads at its open end, said one socket bein adapted for reception of afuse, a remova 1e closing cap 'forsaid fuse socket, said cap being screwed onto the branch containing said fuse socket, and wires embedded in said body and connected with said linings and contacts in a manner to fuse one of the remaining sockets and to render the other socket unfused.

2. An electrical appliance of the class described comprising a single bodyof insulation material having a plugatone end adapted to be tapped into a wall socket, having a pair of diverging branches at its oppositeend and a single branch on one side, all of said branches being formed with sockets lined with electroconductive material,

each socket being provided withna central .contact and said side socket being provided with external screw threads at its open end, said one socket being adapted for reception of a low current capacity fuse, a removable closing cap for said fuse socket, main conducting wires connected with the pin and with one of the diverging branches, an supplemental current conducting wires connect- In testimony whereof I afiix my sigma-c ture.
