(1MM/nul UNITED STATES JOSEPH PHILLIP SCHAEFER, OF MAYFIELD, CALIFORNIA.

OIL-BURNER.

Application filed August 2, 1919.

To all whom t may concern.'

Be it known that Josiirir l). Sciiiiiiinn, a citizen of the United States, residing at Mayfield, in the county of Santa Clara and State of California,ihas invented new and useful Improvements in Oil-Burners, of which the following is a specification.

The object of the invention is to provide an improved form of hydrocarbon burner adapted for use in cook stoves and the like. To this end the invention comprises an improved generator in the form of a tubular ring in which there is inclosed a plurality of balls over which the fuel must pass to reach the jet. The burner is designed to hold the ring-like generator in a vertical position and fuel is admitted to the latter at the upper end thereof, the jet being carried at the lower end of the ring and positioned on the inner periphery so as to direct its llame against a spreader.

A further object .of the invention is to provide a device of this kind which is simple in construction, durable and effective in operation and inexpensive to manufacture.

Other and further objects appear in the following description wherein the invention is set forth in detail.

To the exact construction in which the invention is set forth, it is not to be restricted. The right is reserved to make such changes or alterations as the actual reduction to practice may suggest, in so far as such changes or alterations are compatible in spirit with the annexed claims.

In the accompanying drawings:

Figure 1 is a vertical sectional view through the improved device.

Fig. 2 is a section on the line 2 2 of Fig. 1.

Fig. 3 is a section on the line 3-3' of Fig. 1.

Fig. 4 is a central vertical sectional view through the jet.

Referring to the drawings, the invention comprises a generator 1 which is in the form of a tubular ring provided at a point on its outer periphery with an internally threaded inlet portion 2 adapted to receive a reducing coupling 3 with which a nipple elbow 4 engages, a supply pipe 5 being con nected with this nipple elbow and the pipe connecting with a needle valve 6 to which the fuel supply pipe 7 is led. The generator is mounted in the upright position shown in Fig. 1 with the inlet 2 at the top`and this Specification of Letters Patent.

generator carries on its interior a series of balls 8. The ring 1 at the bottom is formed with an externally threaded nipple 9 to provide for its attachment to the generating pan 10 which is circular in plan and which at its center is provided with an interiiallv threaded hub portion 11 in which the nipple 9 engages. The nipple 9 is internallv threaded so that a drain `pipe 12 mav be attached thereto; this drain pipe beinguconnected with a valve 13 vwhich. when open will permit the draining of sediment or foreign matter from the device and which when closed, will insure the direction of the fuel into the jet 14 which is externally threaded and secured into an appropriate hole formed in the ring or generator 1 on the inner periphery of the latter and in alineinent with the nipple 9. The jet 14 carries a plate 15 which separates the adjacent balls at the lower end of the ring and spaces these balls far enough apart to preclude their free entrance of fuel into the jet.

In orderl that the fuel may readily pass from the pipe 5 into the ring or generator 1. a coil spring 16 is disposed in the inlet por-l tion 2 beneath the coupling 3 and bears on the balls adjacent the inlet to maintain the two on the opposite sides of thev center of the inlet spaced so that they may not obstruct the passage of fuel from the pipe 5 into the ring 1.

The ring 1 on the inner periphery and directly below the inlet 2 is formed with a flange 17, to which a flame spreader 18 is attached by means of appropriate bolts 19.

The device is designed for the burning of kerosene and for distilled and stove oil. If the former is used the opening in the jet 14 is the size of a 68 drill. For distilled and stove oil the opening in the jet is about the size of a 50 drill. The device is designed for mounting in a coal stove, the generating pan serving as a base and being supported on the grate. The pipe 12, if desired, may be led to the exterior of the stove through a suitable hole drilled therein. The needle valve 6 is positioned outside of the stove but it is connected with the burner through the pipe 5 which passes through, a suitable hole drilled in the side of the stove. 0n the opening of the needle valve, a sufficient quantity of oil will be permitted to pass through the generator 1 and out through the j et to enter the generating pan 10. Sufficient oil having been allowed to enter the said pan, the

needle in the valve is closed and the oil in' the pan ignited. By the time this oil has been burned oil, its combustion Will have heated the ring l to a suiicient temperature to cause it to vaporize any oil that may thereafter be permitted to enter. T he opening of the needle valve Will then allow oil to enter the ring l and this triclles over the balls 8, the heat to Which the ring has been raised generating gas which, entering the jet le., will be ignited therein and How therefrom in a dan e directed against a spreader 1.8 which spreads the 'flame and thus keeps the generator ring l hot as Well as generating an intense heat in the stove,

YEhe. fuel purchased from the open market is not al vays clean5 it containing more or less sediment., rl`he draining feature ot the device eliminates all trouble from that source since it permits the draining oi `the burner after use and when the needle valve 6 is closed.

The burners may be built singly or in units containing tivo or more burners depending on the sise ot the stove in which the device is be used.

rElie invention having been described, what is claimed as new and useful is:

il hydrocarbon burner consisting of' a vertically disposed tubular ring-like generator. a supply pipe connecting with the generator on top, jet disposed on the inner periphery of the generator on the bottom, a plurality .of balls housed Within the generator and over which fuel must pass to reach the yet, and a spacer connected with the jet and standing between adjacent balls at the bottom ot the generator to provide for the freedom of flow of fuel from the generator into the jet.

2. A hydrocarbon burner consisting of a vertically disposed tubular ring-like generator, a supply pipe connecting With the generator on top, a jet disposed on the inner periphery ot the generator on the bottoni, a plurality oi balls housed Within the generator and over which fuel must pass to reach the jet, and a generating pan serving jointly as a base for the burner and a fuel holding means to start the initial generation of gas.
