ELECTRICAL APPLIANCE.

Specification of Letters Patent.

Patented June 23,1914.

To all whom, it may concern Be it known that we, SAMUEL B. VAN RANs'r, of Syracuse, in the county of Onondaga and State of New York, and MoR'roN llavnns, Jr., of Albany, in'the county of Albany and State of New York, have invented a certain new and useful Electrical Appliance, of which the following is a specification.

This invention has for its object the production of a highly simple and etlicient electrical appliance particularly suitable foil use in conduit work; and it consists in the novel combinations and structures hereinafter set forth and. claimed.

In describing the invention, reference is bad to the accoi'npanying drawing in which like charactm's designate corresponding parts in all. the views.

Figures 1 and 2 are, respectively, elevational and longitudinal sectional views of one construc ion of said invention. Fig. 3 is a plan view, partly in section, of the detached hollow body of this electrical appliance. Fig. 4 is a sectional view, on line A-A, Fig. 2. Fig. 5 is a view similar to Fig. 2 of another construction of the invention.

This electrical appliance comprises generally a hollow body 1, and a device 2 for the branching of electric circuits. As here illustrated the body 1 is elongated, and its internal chamber is of a width greater than the diameter of the conduit to be connected to said body for facilitating the, necessary manipulation and conne tion of the circuit wires and minimizing the liability of shortcircuiting within the electrical appliance. Said body 1 is also formed with a flattened side?) serving as a base, and with an opening 4 in the side 5 opposed to the base such opening being of less size. than the base. A raised part or post (3 projects from the inner face of the base 3, and is of a height less than that of the opposing sides of the body 1, and greater than the diameter of the circuit wires T passed within the internal chamber of the body 1. Said raised part (3 may consist of a rib, as seen in Figs. landfhorof a cylindrical projection,asillustrated in Fig. 5, and is preferably spaced apart from the inner surfa es of opposing sides of the body 1, thus providing spaces between such raised part and opposing sides of the internal chamber of the body for the reception of circuit wires.

Opposing sides of the body 1 arranged at an angle to the base 3 and the side 5 are formed with parts 8 diverging from the side 5, and the opposite parts of said opposing sides are provided with outwardly-projecting internally-threaded nipples 9, a portion 1Q of each nipple being substantially alined with the flattened base 3, and the longitudinal openings or passages through the nipples 9 communicating with the spaces at opposite sides of the raised parts 6, and being arranged with their axes between, and unequally separated from, the upper and lower edges of t e sides of the body provided with the nipples 9. A conduit for. electric wires is suitably connected to the body 1, said conduit preferably including tubular sections 11 arranged end to end and spaced apart, and screwim into the nipples 9 against shoulders 12 within the inner ends of the lengthwise passages of said nipples. It is thus apparent that opposing sides of thebody 1 are provided with portions of reduced size and formed with openings respectively connected to the conduit and permitting the passage of circuit wires continuously through the nipples 9 and the spaces at opposite sides of the raised part (3.

Preferably, the body 1 is provided with wire-engaging surfaces 13, Fig. 2, diverging from the inner portions of the lengthwise openings or passages of the nipples 9, at an angle to the axes of said nipplts, and with additional internal wire-engaging surfaces 14, Fig. 3, diverging from parts of the inner portions of said openings interposed between the surfaces 123. As best seen in Fig. 3, two of the surfaces 13 diverge from the opening 4 toward the inner portions of the openings or mssages of the nipples 9. Said diverging surfaces 13, 14 being arranged at an angle to the axes of the openings or passages of the. nipples t) facilitate bending of the circuit wires 7 within the hollow body 1 to connect said wiresto the device 2 for the branching of electric circuits and also reduce to a minimum liability of the abrasion or injury of the outer insulating coatings of the wires 7.

The device 2 for the branching of electric circuits serves as a closure for the Opening 1 and thereby forms a part of the inelosing wall of the electric appliance and comprises terminals and a part of insulation which ma be formed in two sections. In Figs. 1 an 2 such device is shown as adapted to receive an electric lamp, the outer portion or end of said device projecting above the side 5 and being provided with a socket extending inwardly from one end and containing the usual screw-shell 15 and central terminal 16 for making contact with the terminals of the lamp. The middle portion of the device 2 substantially fits the opening .4, and the inner portion or end of said device is formed of less size than the opening 4, is movable through said opening into and out, of the internal chamber of the hollow body 1, and is spaced apart from o posing inner surfaces of the body 1 for orming spaces at opposite sides of said portion or end, opening into the spaces at opposite sides of the raised part or post 6, and thus communicating with the longitudinal openings or passages through the nipples 9, the inner end face 17'of said portion or end of the device 2 being mounted upon the raised part 6 and parts of said end face being spaced apart from the inner face of the base 3. Suitable means, as screws 18, movable through the outer surface of the middle portion of the device 2 and extending into the hollow body 1, serves to removably secure said device to the interior of the body 1 and preferably to the raised part or post 6. The portion or end of the device 2 within the hollow body 1 is provided with terminals 19, 20 which extend into the spaces at opposite sides of said portion or end and are electrically connected to bared portions of the circuit wires 7, Fig. 4, and are suitably connected to the terminals 15, 16.

To those skilled in the art it will be understood that the device 2, instead of being in the form of a receptacle adapted to receive electric lamps, may be a rosette intended merely for the branching of electric wires. It will also be understood, as illustrated in Fig. 5, that said device for the branching of electric circuits mayjbe'provided with a shoulder 21. for engaging a rubber gasket 22 mounted on the edge surrounding the openin 4, and that said device may be composed 0 two parts 2 and 2 arranged one above the other and suitably connected together. When the device 2 is of said twopart const'rrretiom-the terminals to which the wires 7 are connected, are elevated sutficiently to cause said wires to engage the surfaces 13, as shown in Fig. 5. In this con- \tI'IIClZlOII the section, or part 2", is attached )y a central screw to the wall 3, or stud 6, projecting from the same, and the section or part 2 is held in place and connected to the section 2 by screws 2.
