DEVICE FOR LIGHTING LAMPS BY ELECTRICITY,

SPECIFICATION forming part of Letters Patent No. 638,565, dated September 26, 1899.

Application filed February 5| 1898. Serial No. 669,237. (No model.)

To all whom it may concern;

Be it known that we, HENRY H. BRIGHAM and SvEND MARTIN MEYER, citizens of the United States, and residents of the city of New York, State of New York, have invented a new and useful Improvement in Devices for Lighting Lamps by Electricity, of which the following is a specification.

The subject of our invention is a device comprising aslidingbar mounted on the lampburner and carryinga resistance-coilof platinum wire or the like adapted to be rendered incandescent by a current of electricity, the movement of the barserving to throw the coil into contact with or proximity to the wicker tip of the burner and also to close an electric circuit, so that when in lighting position the coil will be rendered incandescent and when in retracted position the circuit will be broken and the coil will be removed from the flame of the lamp.

In the accompanying drawings, Figure 1 is a vertical section of a lamp-burner, illustrating one form of our invention. Figs. 2, 3, and I are detail views of the movable coil carrying device on a larger scale. Fig. 5 is an elevation, partly in section, of the lamp reservoir and burner, illustrating a mode of making electrical connection between the shell of the burner and the lamp-reservoir, in the base of which asuitable batteryor source of electricity is located. Fig. 6 is a partial section of the lamp-burner,illustratinga modification.

1 represents the lamp reservoir, 2 the burner, and 3 the cone of the burner, which surrounds the lamp-wick.

6 represents a tubular rod mounted in nearly vertical position within the lamp-,

burner 52, having a longitudinal sliding movement in a socket 4 and drawn down by a spring 13. (Shown in Figs. 8 and 4.) A metallic rod 7, rigidly connected to the interior of the sliding tube 6 and in electrical contact therewith, is connected at its upper end to a platinum coil 8, the other extremity of which is connected to an insulated metallic rod 9, connected by an insulated wire 9 with an external cap 10, which is mechanically connected to the bottom of the tube 6, but electrically insulated therefrom by suitable insulating material 11. The contact of the sliding tube 6 with the fixed guiding-socket 4, in which it slides, places the said tube in constant electrical connection with the lampburner 2, and consequently with the shell of the reservoir or body 1 The act of sliding up the tube 6 moves the coil 8 into contact with or close proximity to the wick or tip of the burner and at the same time throws the metallic cap 10 into contactand electrical connection with a contact-point 14 on the extremity of a conductor 14, which terminates in a socket 15, mounted in an insulator 15 in convenient position for connection or disconnection with an insulated conductor 19, connected to one pole of a battery 20, the other pole of which is grounded by a conduc' tor 21 in the lamp-body 1.

In Fig. 5 we have shown a suitable mode of making the connection in a lamp without re movable fount. This consists ina rod 16, sliding vertically in the terminal socket 15 and slipping at its lower end in a metallic socket 18", mounted on the upper end of an insulated wire 18, which passes down through a fixed tube 1 in the body of the lamp and is connected at its lower end by a wire 19with one pole of a battery 'or suitablesource of electricity 20, located in the base of the lamp, the other pole of which'is grounded at 22 on the lamp-body 1 by a conducting-wire 21. The socket 18 is held in position and insulated by an annular cap 17, of insulating material, mounted in top of the lamp-body 1.

It will be apparent from this description that by slipping up the wire rod 16 within its conncctingsocket 15, thereby raising it completely clear of the conducting-socket 18 and the insulating-socket 17, the burner 2, with its electric attachments, is freed from the lamp-body, so that it may be removed therefrom, as in the case of an ordinary lamp.

The retraction of the bar 6 is effected by spring or gravity the moment it is released. This removes the coil from the flame, con-' ceals it within the guiding-socket 4t, and at the same time breaks the electric circuit, thus preventing any injury to the coil or exhaustion of the battery in the normal condition of the apparatus and excepting at the instant of lighting the lamp.

In the modification shown in Fig. 6 the circuit is closed by an upward-sliding movement of the chimney-gallery 5 and the neck 5, to which it is attached within the shell 2 and cone 3 of the burner. In this illustration the tube 6 is permanently connected to the neck 3 of the cone or chimney-gallery and contains rods '7 and 9, as in Fig. 2, on which the lighting-coil 8 is mounted, the one rod being in electrical connection with the tube 6, while the other, 9, is insulated therefrom by insulating-sleeve 9" and terminates below in a contact-head 10, which by the upward movement of the chimney-gallery and attached parts makes contact with the arm lat, connected to the insulated conducting-socket 15, as shown in dotted lines, thereby closing the circuit through the coil 8 at the same time that this is elevated in contact with or ,proximity to the wick. The rod 7, (shown in Fig. 2,) by which the grounded connection is made between one end of the coil 8 and the tube 6, is hidden in Fig. 6. In this illustration the electric connection of the tube 6 with the metal body of the lamp may be by its direct attachment of the said tube to the neck 5 of the chimney-gallery and the sliding contact of this with the burner-shell 2, or this ground connection may be made by the contact of the upper end of the tube 6 with fixed cone 3 of the burner, as shown in dotted lines.

Having thus described our invention, the following is What we claim as new therein and desire to secure by Letters Patent:

1. An electrical device for lighting lamps comprising a suitable source of electricity and conductors; a resistance-coil adapted to be rendered incandescent by the electric current; a sliding bar mounted on the burner, and on which the coil is mounted, and whereby it is carried to and away from the wick or igniting-point of the burner, and a contact device with which the coil-carrying bar engages so as to close an electric circuit through the coil in the act' of moving the coil into lighting position as explained.

2. An electrical device for lighting lamps, comprising a resistance-coil adapted to be rendered incandescent by an electric current, a sliding bar on which said coil is mounted and the movement of which advances the coil to position for lighting the burner and retracts it from such position, a suitable source of electricity and conductors, connected at one end with the movable bar and terminating at the other end in a contact-point with 1 which the movable bar forms electric connection so as to close a circuit through the coil in the act of moving the coil into igniting position, substantially as explained.

An electrical device for lighting lamps, comprising a suitable source of electricity, conductors connected therewith, a sliding bar mounted on the lam p-burner connected with one pole of the conductors and adapted by its movement to make and break connection with the other pole and having an insulating device interposed between its ends which thus connect with the respective poles of the battery, and a resistance-coil carried by the sliding bar and electrically connecting the ends thereof, whereby the forward movement of the bar will close an electric circuit through the resistance-coil and advance the said coil to lighting position and the retraction of the bar will break such circuit and remove the lighting-coil from the flame of the lamp as explained.

4;. An electrical device for lighting lamps comprising a suitable source of electricity, and conductors, a resistance-coil adapted to be rendered incandescent by the passage of an electric current, a sliding bar in which said coil is mounted, adapted to be advanced by pressure of the finger and retracted automatically when released, and in its advance movement carrying the coil to lighting position and at the same time placing its ends in electrical connection with the respective poles of the conductors, thereby closing an electric circuit through said coil, as explained.

5. In an electrical device for lighting lamps the combination of a suitable source of electricity and conductors connected therewith, a coil adapted to be rendered incandescent by the electric current, a sliding bar, carrying the said coil, mounted in the lamp-burner and adapted in its forward movement to carry the coil into lighting position and also close an electric circuit therethrough, and a shield or casing within which the said coil is concealed in its retracted position, substantially as set forth.

In testimony that we claim the foregoing as our invention we have signed ournames, in presence of two witnesses, this 12th day of January, 1898.
