LIQUID-FUEL-BURNING INCANDESCENT LAMP.

SPECIFICATION folming part of Letters Patent N 0. 783,248, dated February 21, 1905. Application filed 0mm 25,1902. Serial NO. 128,818.

To all whom it flea/y concern:

Be it known that I, J osErH DANISOHEVSKI, a subject of the Emperor of Russia, residing at St. Petersburg, Russia, have invented certain new and useful Improvements in Liquid- Fuel-Burning Incandescent Lamps, of which the following is a specification.

invention relates to liquid-fuel-burning incandescent lamps, and is designed to simplify, cheapen, and render more efiicient burners of the class to which it belongs.

The invention consists of a reservoir for holding the liquid fuel, means for filling the same, mechanism for forcing the liquid from the reservoir atan even and continuous pressure to the burner, and means for returning the liquid to the reservoir.

In the accompanying drawings, Figure 1 is an elevation, partly in section, of a streetlamp embodying my invention. Fig. 1 is a vertical section of the base portion of alamppost having a weight suspended therein; Fig. 2, an enlarged detail side elevation, partly in section, of the liquid-reservoir; Fig. 3, a top plan view of the reservoir and supply-tank; Fig. 4, an elevation of a modification, showing my improvement applied to a portable lamp.

As an example of the adaptability of my lamp, I have shown it in Fig. 1 mounted on an ordinary street-lamp post A, having brackets A at the top 'which support both the liquid-fuel reservoir and the lantern portion. The reservoir comprises a compressible re' ceptacle a, preferably made of a flexible material in the form of a bellows and coated with any compound which will resist the passage of oil. This receptacle (4 is mounted on and connected to a base-plate a, bolted to the brackets A. To the top of the reservoir is connected a plate a movable toward and from the base-plate a between guide-pieces b, bolted on two sides of the base-plate at;

These guide-pieces are connected at their tops by a cross-plate a, carrying a standard (Z, centrally mounted thereon. A shaft 6 is journaled in a bearing-piece 0, formed on one of the guide-pieces or on one end of the crossplate 0 and in bearings formed in two arms (Z of the standard (Z. A pinion 0', mounted on I the shaft 0 between the two arms of the standard, engages a rack-bar a centrally connected to the top plate a and projecting up through the standard. A pawl f, preferably provided with forked arms which straddle the pinion e and by means of which it is loosely journaled on the shaft e, is adapted to be thrown into and out of engagement with the rack-bar. For this purpose a lever g, loosely mounted on the shaft, is connected to the pawl by means of a coiled spring g.

In the top plate a is formed an opening a, into which latter is inserted a tube la, and connected to this tube, by means of a couplingnut h, is a flexible hose if, leading to a supply-tank X, as shown in Fig. 3.

A vaporizer V is preferably mounted above the reservoir, as shown in Fig. 1, and is supplied with liquid therefrom by means of a pipe of which enters the reservoir through the base-plate a. An incandescent burner Y is preferably situated below the vaporizer and is connected therewith by a pipe 1 The liquid fuel contained in the reservoir is forced through the pipe 0; to the vaporizer by means of the collapsing of the reservoir. This is accomplished by means of a weight P, which, as shown in Fig. 1, is suspended in the post A and connected to the top plate a by means of a cord or, if desired, a weight P may be mounted directly upon the top plate (4 as shown in Fig. 2.

A coiled pipe W surrounds the reservoir and is in communication at one end with the upper part of the reservoir, while the other end communicates with the supply-pipe 1/ near where it enters the bottom of the reservoir, as shown in Fig. 2.

The operation of the device is as follows: When the reservoir is empty,and consequently collapsed, it is filled in the following manner: The tube it is inserted in the aperture 0* of the top plate and is coupled, by means of the nut it, with the flexible hose if, which latter is placed in the storage-tank X. The shaft 0 is then rotated by means of the handle 70, and

causing the oil to flow from the tank into the reservoir, and after the reservoir has been filled the pawl fis thrown into engagement with the rack to prevent the weight P from descending.

The pipe If is then disconnected and the aperture in the reservoir closed by means of a nut or any suitable stopping device. When it is desired to light the lamp, the vaporizer is heated, and the flow of oil thereto is started by simply releasing the pawl from engagement with the rack by means of the lever g, and a constant flow is insured by the pressure of the weight upon the reservoir. To extinguish the lamp, it will be suificient to raise the weight P by turning the handle is, releasing the liquid fuel from pressure and at the same time creating a vacuum in the reservoir above the fuel. The lamp is extinguished at once without smoke or exhalations, and toprevent evaporation of the liquid fuel which would ordinarily remain in the pipe u up to the liquid-level in the reservoir the cock o is turned to shut off the supply from the reservoir, and the liquid left in the pipe is drawn back into the reservoir through the pipe w by means of the vacuum in the top of the reservoir.

Having thus described my invention, what I-elaim as new therein, and desire to secure by plate, a pinion in engagement with said rack,

means for rotating the pinion, and means for locking the rack-bar, substantially as described.

2. In a liquid-fuel incandescent lamp, the

combination of a flexible reservoir, a stationary support therefor, a plate connected to the top of the reservoir, a weight supported by the top plate, guides for the top plate mounted on the base-plate, a plate connecting the guides, a standard mounted on the connecting-plate, a rack-bar connected to the top plate and projecting through the standard, a shaft having bearings in the standard, a pinion on the shaft in engagement with the rack-bar, a pawl adapted to engage said rack-bar, and means for operating the pawl, substantially as and for the ture formed thereinfmeans for compressing the reservoir and means for expanding the same, of a supply-tank, and a feed-pipe secured in the aperture and communicating with the tank, whereby when the reservoir is expanded fuel will flow from the tank into the reservoir, substantially as and for the purpose specified.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
