OIL AND GASOLENE GENERATOR AND BURNER.

Specification of Letters Patent.

Patented Apr. 2, 1918.

Application filed August 23, 1917. Serial No. 187,834.

To all whom it may concern:

Be it known that we, IIENRYIIUNT and OSCAR S. PRICE, citizens of the United States, residing at Greentown, in the county of Howard, State of Indiana have invented a new and useful Oil and (fasolene Generator and Burner, of which the following is a specification.

The device forming thesubject matter of this application is a combustion device adapted to be employed for turning liquid fuel, such as kerosene oil or gasolene, into gas, and the invention aims to provide novel means whereby the heating of the fuel, to turn the same into gas, is brought about.

Another object of the invention is to provide novel means whereby the gas may be mixed with air, and whereby a proper adjustment of the gas-supplying nozzle, with respect to the air inlet may be brought about.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in top plan, a combustion device embodying the present improvements;

Fig. 2 is a cross section taken on the line 22 of Fig. l;

r Fig. 3 is a side elevation of the combustion device shown in Fig. 1;

Fig. 4 is a fragmental longitudinal section through the mixing means;

Fig. 5 is a cross section taken on the line 55 of Fig. 4.

The device forming the subject matter of this application comprises a U-shaped conduit including lower members 1 and 2. The lower members 1 and 2 are disposed in parallel relation and at the same level. The conduit above mentioned includes upper members 3 and 4. The members 3 and 4 are disposed in parallel relation, and at approximately the same level. A vertical connection 5 unites the inner end of the upper member 3 with the inner end of the lower member 2. A vertical connection 6 unites the inner end of the upper member 4 with the inner end of the lower member 1. The outer ends of the upper members 3 and 4 are united by an end tube 7 which is horizontally disposed. United with the outer end of the lower member 1 is a horizontal extension 8 in which is interposed a valve 9, the valve 9 preferably being a needle valve. The extension 8 projects toward the longitudinal center of the device, and its inner end is united with an elbow 10, carrying a nozzle 11 which projects, along the longitudinal center of the structure, parallel to the elements 2, 3, 4 and 1. The nozzle 11 is supplied at its end with a gas outlet 12. The nozzle 11 is externally threaded as shown at 14 to engage within a reducer 15 having a turning flange 16. The reducer 15 is threaded into a larger reducer 17 hav ing a turning flange 18. The reducer 17 is threaded into one end of a tubular mixing sleeve 19 having an air inlet 20. One end of a burner tube 21 is threaded into the sleeve 19 or is otherwise secured thereto. The burner tube 21 is disposed parallel to the elements 8, 4, l and 2, and preferably is arranged in the same horizontal plane as the lower members 1 and 2 of the conduit. the burner tube extending beneath the end member 7 of the conduit. The burner tube 21 is provided with orifices 23 which preferably are inclined laterally, so as to discharge toward the members 3 and 4. The outer end of the burner tube 21 is closed by a cap 24. The outer end of the lower member 2 is provided with a lateral extension 25 carrying a valve 26 which may be a needle valve. By means of a coupling 27 the casing of the valve 26 is connected with a so-called hollow wire 28 whereby the fuel, such as gasolene or kerosene is supplied.

In practical operation, the fuel passes through the member 28 and is controlled by the valve 26. Thence, the fuel passes into the lower member 2 and as the fuel rises in the connection 5, the conversion of the fuel into gas, under the action of the flames proceeding from the orifices 23 in the burner tube 21, begins. In the members 5, 3, 7, 4 and 6, the conversion of fuel into gas is carried out, the gas traversing the lower member 1 and passing by way of the extension 8, and the elbow 10 into the nozzle 11,

the flow of gas being controlled by means of the valve 9. The gas passes out of the nozzle 11 by way of the outlet 12, into the sleeve 19, air being admitted into the sleeve through the inlet 20. In the sleeve 19, a mixture of gas and air is efiected, and this mixture passes into the burner tube 21, the mixture burning in a plurality of jets at the orifices 23, these flame jets serving to heat up the elements 5, 6, 4, 3 and 7, of the U-shaped conduit, to efiect a conversion of the liquid fuel into gas, as above described.

The position of the outlet 12 of the nozzle- 11 with respect to the air inlet 20 of the mixing sleeve 19 may be adjusted by rotating the reducer 15, the nozzle 11 in this way being moved longitudinally with respect to the mixing sleeve 19. Since two reducers 16 and 17 are employed, the reducer 15 may be omitted if desired, thereby permitting a larger nozzle than the one shown in the drawings, to be threaded directly into the reducer 17. Since the connection 5 stands upright, the fuel supplied to the lower memher 2 will be prevented from running, in liquid form, into the parts 3, 7 and 4t. The construction of the device, therefore, is such that it will be practically impossible to flood I the burner tube 21 with liquid fuel.

Having thus described the invention, what is claimed is 1. In a device of the class described, a U- shaped conduit comprising approximately parallel lower members, approximately parallel upper members disposed at a higher elevation than the lower members; a tube a connecting the outer ends of the upper members, and upright connections uniting the inlower members; and a source of fuel supplycommunicating with the outer end of the other lower member.

2. In a device of'the class described, a U-. V

shaped. conduit comprising approximately parallel lower members, approximately parallel upper members disposed at a higher elevation than the lower members, a tube connecting the outer ends of the upper members, and upright connections uniting the inner ends of the upper members with the inner ends of-the lower members; a tubular burner disposed between the upper members and between the lower members; a nozzle connected with the outer end of one lower member; a reducer structure threaded upon the outside of the nozzle; and a sleeve having a lateral air inlet, the nozzle projecting into the sleeve to a point adjacent to the inlet, the sleeve being threaded upon the outside of the reducer structure and upon the outside of the burner, whereby the sleeve may be grasped and rotated to adjust the position of the inlet with respect to the inner end of the nozzle.

In testimony that we claim the foregoing as our own, we have hereto aflixed our signatures in the presence of two witnesses.
