PHILIP I-I. FIELDING, OF NEW YORK, N. Y.

ELECTRICAL RECEPTACLE.

SPECIFICATION forming part of Letters Patent No. 714,291, dated November 25, 1902.

Application filed February 20, 1902. Serial No. 94,909. (No model.)

To aZZ whom it may concern:

Be it known that I, PHILIP H. FIELDING, a citizen of the United States,residing at the city of New York,in the borough of Manhattan and State of New York, have invented certain new and useful Improvements in Electrical Receptacles, of which the following is a full, clear, and exact description.

This invention relates to electrical receptacles, rosettes, and similar electrical devices used at points where a branch circuit is taken off from a main circuit, the object of the invention being to provide a simple device which can be manufactured at low cost, which will effectually cover naked portions of the wires at the joints, furnish means for inclosing the fuses commonly used in such devices, and affording a construction which will in every way meet the requirements of the rules of fire-underwriters.

With these objects in view my invention consists of a receptacle or similar device constructed in the peculiar manner hereinafter described, and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a plan of a receptacle complete and in connection with the main wire. Fig. 2 is a plan of the device with the cap removed. Fig. 3 is a side elevation of the base part, showing a portion of the cap in dotted lines and portions of the base broken away. Fig. 4 is a section on lines a: w of Figs. 1 and 2. Fig. 5 is a central transverse section of the cap. Fig. 6 is a perspective view of the cap with part broken away, and Fig. 7 is a perspective view of the base before the metallic portions are applied thereto.

The form of device shown is that of an electrical receptacle adapted to receive an incandescent lamp of the Edison type and to be used for surface wiring with cleats. The receptacle consists of the two principal parts A and B, the former being the base and the latter the cap, both being of porcelain or other suitable insulating material. The base is an elongated structure having grooves a extending across its ends for the main circuit-wires w and w, respectively. Between the grooves there is a raised portion ct, to the center of which is fixed a cylindrical threaded shell or socket b and a metallic center plate Z), adapted to engage,respectively,with corresponding parts on the neck of the lamp. The plate 12' carries a binding-screw 12 while the shell Z9 carries a binding-screw 5 located on the opposite side of the raised portion a. Each end of the raised portion a is provided with a deep groove 0, which extends in an oblique direction from a point near the screws 1) or b to the groove a for the line-wire. At the outer edge of these grooves and fixed to the perpendicular faces of the raised portion a by means of screws (1 are metallic clips d, which reach downward into the grooves a and are there provided with binding-screws d for gripping the line-wires, the insulation from which is removed for this purpose, as shown in Fig. 2. The grooves c furnish a passage for fusible conductors e and e, which extend from the binding-screws d, respectively, to the binding-screws b and b and. thus complete the circuit from the two wires to w to the two parts of the lamp-socket.

The cap Bis formed with acylindrical opening f, adapted to inclose the shell I), and with cut-away portions permitting it to fit down against and over the edges of the raised portion a until it covers with its flat surface f the corresponding surface 9 on the base and extends over the grooves a. The cap is also provided with integral elongated plugs c', which are locatedin such a position that when the cap is adjusted to the base they will enter and close the top of the respective grooves c 0, containing the fuse-wires, as clearly shown in Fig. 4, and thus provide what is known in the art as an inclosed fuse. The passages for the fuses might also be formed by perforating the raised portion a, and thus make the inclosu re wholly in the base part of the receptacle; but on account of the difficulty of molding the perforations it is considered better practice to form the grooves and close them afterward with the cap in the manner described. In case the perforations were used instead of grooves the fuse-wire would have to be threaded through them, which would require a little more time in adjusting the parts for service. Having described my invention, I claim- An electrical receptacle or similar appliance consisting of a base part and a cap of insulating material, binding devices for conductors located at difierent points on the base In Witness whereof I subscribe my signature in presence of two witnesses.

PHILIP H. FIELDING.
