HYDROCARBON-BURNER.

Specification of Letters Patent.

Patented Dec. 9, 1919.

Application led September 2-5, 1918. Seria1`No.v255,647.

To all whom t may concern Be it known that I, FRANK Hassan a citizen of the United States of America, and a resident of Chicago. county of (look, and State ot' Illinois, have invented certain new and useful Improvements in Hydrocarbon Burners. of which the following is a specification. y

This invention relates to hydrocarbon burners adapted mainly for use in the fire pots of furnaces, stoves, ranges and such devices, though not necessarily limited to such use.

The main objects of the invention are to provide an improved form otl burner for stoves and the like and particularly a compound burner having a plurality of burner arms adapted for adjustment by swinging the arms to different relative positions; to provide for varying the effective heating area of the, burner and the intensity of the heat, by turning the direct-ion of one or more of the fuel outlet parts or arms in diierent directions; and to provide suitable torch and preheating means adapted for use in combi* nation with sucb swingingly mounted burner arms, in a manner best adapted for convenience in use and efficiency in operation.

' An illustrative embodiment of this inven.-

tion is shown in the accompanying drawings in which:

Figure 1 is a plan of the burner.

Fig. 2 is a side view with one of the burner tubes removed, the View being nearly on the line 2-2 of Fig. 1.

Fig. 3 is a front elevation.

Fig. 4.- is a cross section of the burner tubes and connector on the line 4-4 of Fig. 2.

Fig. 5 is an axial section through the gas discharge nozzle and valves.

In the illustrative embodiment shown in the drawings, the burner as a whole comprises a relatively stationary supporting part or frame 1, whereon the other parts are detachably mounted, namely, a fuel supply and vaporizing member 2, a combined air mixing and gas distributing member 3, a pair of tubular gas nozzles orfburners 4 each turnably connected medially to said member 3, a torch 5 for starting the burner, and a small vaporizing coil 6 therefor.

Each ot' the burner members 4 is provided with a central hub part 7 adapted for swinging on the hollow pivot members 8 disposed on the arms 9 .of the member 3. The said pivots are arranged with their axes in the same .Vertical plane and the said aXes are disposed at an angle of abouti-45 degrees from vertical. hence being atan about 90 degrees from each other.

.Each burner part 4 is provided with a series of lateral apertures 10 on one side, the position ot said series of apertures-.or the zone thereof as a whole being about 45 degrees from the axis of the pivot so that when .the said burner part is disposed horizon- .tures nearest together, that is to say, on the upper side (see Fig. 4) whereby the flames are directed upward side by side. If it is desired to distribute the heat or spread the.

flames over a wider area, the burner members are reversed so that the flames shoot out sidewise in opposite directions and the heat is thereby spread out over a wider area but is less intense at any particular point. The position of the outlet in this position is between the. dotted lines l0a and 10b on` Fig. 4.. The burner may be readily changed from one position to the other by reversing the position ofLthe tubular members and the corresponding distribution of heat may be obtained thereby in accordance with the conditions to be met in any particular instance or from time to time as conditions may change.

The said frame 1 com )rises a air of leo" members at the front and rear ends respectively, each consisting of a r,bar formed with its middle part 11 disposed horizontally and with its ends turned down to serve as legs 12, as bestl shown in Fig. 3. A. plate 13 is disposed between the burner tubes L and is attached adjacent to its ends to the Said parts 11 of the leg members by suitable means as screws 14. The front end 14' of plate 14 is turned up as shown in Fig. 2'. The. ends 14 bear against the tubes 4 and cooperate with the outwardly turned knees 12 ot' the legs 12 to grip said tubes. There is also provided at each end ot' the. frame an upwardly disposed bracket or clamp member lalso held in place medially by angle of 'isv the corresponding screws 14. The ends 1G of said brackets 15 are turned upward and inward to clasp the parallelly disposed arms of the U-shaped vaporizing member 2, the latter being slidable lengthwise therein when the connector 17 is released, as hereinafter described. On the front end of the plate 12 is attached a sheet of asbestos adapted to receive a suitable charge of oil from the pipe 6, and so constitute the torch 5.

The said pipe 6 is formed with a long tubular connection extending fromy the connector 17 upward through an aperture 18 in the middle part of plate 13 and a spirally coiled part terminating at the front end in a rearwardly facing nozzle 19 adapted to throw a stream of oil backward onto the asbestos and into the coil, this being shown in Fig. 1. The ti 20 of the tube 6 is sealed and the said nozz e for the escape of fuel is disposed on the inner side of the rearwardly turned end part of the pipe.

The mixing chamber 3 comprises a forwardly extending part 21 which is cut away and left open at the lower front corner, as shown at 22. The closed upper part fits over the gas nozzle 23, and air is admitted through the opening 22 so that air and gas will be carried forward together and mixed as it approaches the upwardly turned arms 9 which lead to the corresponding burner tubes 5.

Fuel is supplied to the vaporizing chamber through the valve mechanism 24 on the front end of the right hand arm of the vaporizer as viewed in Fig. 1. The lower valve member 25 supplies liquid fuel to the torch through the pipe 6 and the upper valve supplies fuel to the vaporizing chamber. 0n the front end of the opposite or left arm is provided a valve attachment 26 including a pair of valve members. The upper valve 27 controls the flow of the fuel vapor through the gas nozzle 23 into the mixing chamber, and the lower valve 28 controls the waste blow-off nozzle 29 and is normally closed.

The operation for reversing the position of the burner tubes is as follows: First disconnect the priming torch-coil 6 by unfastening the connector 17 then withdraw the vaporizing member 2 by relative forward movement thereof with respect to the frame 1, then remove the frame screws 14 so as to permit the leg members 11-12 to separate meagre@ from the frame plate 13 and both are removed from the burner tubes, which then remain connected solely by the angular gas supply member 3 9. The burner tubes are then free to be turned on their respective pivots and may be reversed one after the other.

The operation for assembling the device is as follows: The combined fuel mixing and distributing chamber and burner tubes being in their normal position with the burner apertures facing either upward or outward, the frame plate and leg members are assembled in place and Secured by the screws 14. The vaporizing tube'Q is then inserted by longitudinal movement lengthwise of the burner tubes in a backward direction from the frontend of the device. The priming spiral is then inserted and secured in place by setting the connector clamp 17 in place, whereupon the device` is ready for use.

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined hy the following claims.

l claim:

1. A hydrocarbon burner, comprising a relatively stationary support having a pair of hollow pivots disposed with their axes at an angle of about 90 degrees, in combination with a pair of tubular burner members swingingly mounted on said pivots respec tively, the pivotal attachment of said members being central on one side thereof respectively, and the fuel apertures of each of said members being disposed in a longitudinal zone about 45 degrees from the corresponding pivotal axis.

2. A hydrocarbon burner, comprising a vaporizing tube having a combined discharge valve and nozzle device at one end, and a fuel supply valveI device at the other end, thc formerI of said devices including a gas discharge nozzle and waste collecting means thereunder. said collecting means having a valve adapted for manual control to release the waste material from time to time.
