Specification of Letters Patent.

Patented April 10, 1906.

Application filed January 30, 1905. Serial No. 243,274.

To all whom it may concern.-

Be it known that I, ALBERT P. SEYMOUR, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Receptacles for Incandescent Electric Lamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. a

My invention relates to receptacles for incandescent electric lamps, and has for its object to produce a receptacle of strong and simple construction, in which the metallic parts are well supported and protected and 'which may be easily installed, adapting it for temporary use, as for decorative illumination. Its essential features are an insulating supporting-base, preferably made in two parts and composed of a cap and a body, as here shown. It is provided with grooves, channels, or some e uivalent having external openings in which t e conductors may be arranged easily without separatin or disturbing the relation of the cap an body after the receptacle has been initiall assembled. Screws are provided, respective y, in the opposite legs of the circuit, which engage with the respective conductors to make electrical connection therewith and firmly to secure the receptacle in position.

In the drawings I have illustrated a desirable embodiment of my invention, in which the reference-numerals of the specification indicate the corresponding parts in all the figures.

Figures I and II are vertical sections at right angles to each other. Fig. III is a side elevation. Figs. IV and V are isometric views of the body and cap separated, the cap being inverted. Fig. VI is a vertical section of a modified form of my device.

1 indicates the body, and 2 the base or cap, made of porcelain or other suitable insulating material.

3 and 4 indicate suitable lamp-terminals arranged on the body, here provided with the usual mouth 5 to receive the lamp-base.

6 and 7 are respectively the wire terminal pieces of any suitable form and arrangement. Here. the outer lamp-terminal 3 is in the form of a copper or brass threaded shell secured to the terminal piece 6 by screws 9 9, which act both as electric conductors and as securing-screws for the two parts, clamping them bothto the bod This terminal piece 6 may be formed with forked ends arranged in cut-outs 10 in the upper surface of the bod Central terminal 4 is the head of the sing e screw 11, which is also an electric conductor in the other leg of the circuit, and the mechanical means for securing in place on abutment 12 the second terminal piece 7 and also for connecting the cap to the body for instance, by engagement with nut 14, ar-

ran ed in recess 15 in the top of the cap and preferably covered by insulating cement or other insulating material. The cap on its lower surface is provided with suitable parallel channels 17 17, having external openings to receive the conductors 18, the terminal pieces 6 and 7 being formed to correspond to the grooves and fitted to beds or recesses 20. The upper surface of the cap is preferablp domed, and its lower surface is formed wit wall 22, fitting cut-outs 10 and abutment 12,

positively to separate and insulate the two terminal pieces and with a depending margin 26 to protect the upper portion of the ody and the metallic parts.

indicates grooves in the margin to receive and permit access to the heads of the screws 27 27, arranged in the outer ends ofthe terminal pieces, and 23 indicates the lips or portions of the margin between the channels. To en age with a naked wire, these screws could have blunt tips; but as conductors for these purposes are now commonly inclosed in insulating material the screws should be pointed to perforate the insulation and to engage with the wire in the interior or to penetrate between the strands of the usual stranded conductor. At 29 29 the upper portion of the body is beveled or cut away to permit the conductors easily to be arranged in the channels.

32 is a washer with resilient ends, which may be arranged on terminal 4 for making a good contact with the base of the lamp, and 33 a mica washer also arranged on said terminal to insure insulation from outer lampterminal 3.

In the first five figures of the drawings I have illustrated my preferred form of receptacle, in which the contact-screws are conveniently operated from the sides; but in Fig. VI, I have shown a sim )le modification in the form of the arts, and particularly in the arrangement 0 said screws, which may be more convenient for certain uses and locations. Here the terminal pieces are of slightl -difl"erent form and arranged against the sid cs of the body, so that the screws in their ends are inclined down and out. Beds 20 and grooves 25 in the ca may be omitted.

I have shown a desirable construction of receptacle, but do not desire to limit myself to the form and arrangement of parts shown, as they may be varied without departing from the spirit of my invention.

It will be understood that my receptacle is particularly adapted for the use for which it is intended, because when installing it is not necessary to separate the body from the cap. The conductors or cables may be laid parallel on the floor or elsewhere and my receptacles quickly connected thereto merely by arranging one conductor in its channel and tightening the corresponding screw, which perforates the insulating material and makes ood contact with the wire in the interior wit out stripping, or if the conductors are strung in the air the installer can move along from place to place, carrying a supply of receptacles, connect each receptacle to one conductor, as aforesaid, whereby the receptacle is securely supported, and then connect to the other conductor, all without separatingthe parts and in the most convenient way, whether the current is turned off or on. The domed cap tends to shed water falling from above, and its margin protects the terminals from'the weather and from accidental contact and short circuits. By the arrangement of the terminal ieces moisture flowing down the wires would with difficulty flow into the interior of the receptacle, causing leakage of current or short circuit.

My receptacle is simple and economical to construct and install. It is compact, so that the conductors are firmly secured near the center, and et all parts well insulated. It is easily insta led, easily detached, and easily rearranged, all without injuring the device itself or the conductors.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
