v UNITED, STATES EDWARD P. BECKWITH, onennnrson, NEW YORK.
To all whom timely concern Be it known that I, EDWARD P. Bram WITH, a citizen of the United States, residing at Garrison, county of Putnam, and St' te of New York, have invented certain new and useful Improvements in Electric Incandescent Lamps, fully described and represented im the following specification and the accompanying drawings, forming a part of the same.
This invention relates to improvements" in electric incandescent lamps, and its object generally speaking is to produce an electric incandescent'lamp having a simple, cheap and effective holding device for positioning the filament in the lamp, said device lending itself readily to the disposition of the filament therein, and to produce a lamp having a minimum amount of non-incandescent material located within the bulb.
With, these and other objects not specifically referred to in view, the invention consists in certain constructions and in cer-' Y tam parts, lmprovements and combmatlons ,as will be hereinafter fully described and v p then specifically pointed out.
. mg the ment and holder, view taken on the Referring to the acompanying drawings: Figure 1 represents a front elevation of a lamp with the bulb partly broken away; Fig. 2 is a side elevation showing the filaand Fig. 3 is a sectional line 33 of Fig. 1.
In constructions embodying the invention the holder for the filament will include an insulating bar around which the filament is given a plurality of turns, so that the bar supports the filament at a plurality of points. In the best constructions embodyinvention a plurality of such bars will be eniployed.The particular configuration of the bar or bars and the means for supporting it or them within the lamp may be widely'varied, but in the best con-v structions embodying the. invention a plurality of bars will be employed, the filament'being strung from one to the other and neck of the lamp at.12.
being supported directly upon the bars. In -the particular construction shown,the bars 10 and 11 are formed with angular parts 10 and 11 respectively,

, insulated from the filament at the points of This insulation Ways, but it may contact with the filament. may be provided in various well be accomplished by forming a thin paste of bauxite, glass and clay, dipping the bar or bars therein and then fusing the coat- The formation of an insulated support for a filament in the manner described is set forth and claimed in a companion application Ser; N 0. 672,684, filed at even date herewith, and such a support is not, therefore, broadly claimed in this application. In order to prevent slipping of the filament on the bars, the bars may be provided with slight depressions which may take the form of nicks or bends in the bar, as indicated at 14.
In constructions embodying the invention the insulating bar should include a conductor to transmit current from the leading in Wires to the filament. The particular form of the conductor or conductors may be widely varied, but in the best constructions embodying the invention'the bars themselves are made of conducting material which is insulated at the filament-supporting points as described above. In the particular construction shown, the filament is electrically connected to the ends of the bars, as indicated at 15 and 16 in Fig. 3. The other ends of the bars besides being fused in the glass neck 12, as described, are also in electrical connection with the leading in wires 17 and 18 through which current flows to the filament.
Changes and variations may be made in the construction by which the .invention'is carried into effect. The invention claimed, therefore, is not to be confined to the particular construction herein shown and described. 1
-What is claimed is 1. An electric vacuum lamp comprising a filament and a holder for the filament adapted to support the same at a plurality of points and also to act as a conductor, the holder being insulated from the filament at the supporting points of contact therewith.
2. An electric vacuum lampcomprising a filament and a pair of conductors for-thefilament, the said' conductors being adapted to support the filament at a plurality of points, the conductors being insulated from the filament at the supporting points.
3. An electric vacuum lamp comprising a. filament and a conductor to transmit electricity to the filament and to furnish a plurality of points of support for the filament,
the conductor being insulated from the filament at the supporting points.
4. An electric vacuum lamp comprising a plurality of conductor bars disposed in parallel relation, a metal filament having a plurality of turns about said bars and supported thereby, and a heat and electrical insulating medium interposed between the bars and the filament.
I 5. An electric vacuum lamp comprising a plurality of conductor bars disposed in parallel relation, a metal filament having a plurality of turns about said bars and supported thereby, and a heat and electrical insulating medium interposed between thebars and the filament.
6. In an electric vacuum lamp, a filament, and a holder for the filament adapted to support the filament at a plurality of insulated points and having an electrical connection with the filament.
In testimony whereof, I have hereunto set my hand, in the presence of two subscribing witnesses.
