To all whom it may concern:

Be it known that l, BERT E. HADLEY, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Gas Maker and Combustion Apparatus, of which the following is a specification.

This invention relates to a gas generating and combustion apparatus and the object of the invention is to provide an apparatus for converting kerosene oil into gas or vapors, admixing air therewith, and burning the resultant highly inflammable mixture. Another object isto provide a gas generator and burner of the above character which is comparatively silent in operation, thus obviating the objectionable noise common to oil burners. Another object is to provide means for efl ecting a rapid and complete conversion of the fuel oil into hot vapors, and to provide means for thoroughly mixing air with the vapors. A further object is to provide a vaporizer nozzle which will not readily become clogged. Uther objects will appear hereinafter.

The invention is illustrated in the'accompanying drawings, in which:

Figure 1 is a. view of the apparatus in side elevation and partly in longitudinal section.

Fig. 2 is a plan view with arts broken away showing one of the rnui ers in horizontal section.

Fig. 3 is a view of spectlve.

Fig. 4L .is a detail vertical section of the vaporizer tip.

in carrying out my invention ll employ a cylindrical or tubular burner 5 which 1s preferably formed of pipe threadedat both ends to receive caps 6 and 7 fitted with supporting legs 8. The cylinder is formed with a series of burner openings 9 on its sides and has similar openings 10 on its upper portion. The cap 6 is formed with a threaded central opening into which one end of a Ill-coupling the apparatus in. per- 11 is screwed. Extending transversely of the cylinder is an air inlet tube 12 having a threaded opening intermediate its ends into which the other end of the coupling is screwed. An aperture 13 is formed in the tube opposite the opening leading into the throat 14 formed by the coupling, and extending into this aperture is the tip 15 of a vaporizer tube 16 disposed parallel with the cylinder 5 opposite theopenings 10. The outer end of the vaporizer tube is screwed into a reduction nipple 17 removably threaded into a coupling 18 rigidly held on a. bracket 19 secured to the cap 7. A fuel feedv pipe 20 leading from any suitable source of supply connects with the coupling i 18, being detachably secured thereto by a cap 21 screwed on the coupling and engag mg a flange formed on the end of the pipe.

The vaporizer tip 15 is constructed as shown in Fig. l-, and comprises a plug 22 screwed into the end of the vaporizer tube and having a recess 23 opening to the tube in which several layers of screen, formed of wire gauze, are mounted. A plurality of passages 25 lead from the recess 23 to the outer end of the plug and communicate with tubes 26 or projections extending beyond the end face 0 the plug. Screwed on the outer end of the plug is a cap 27 which is formed with a central end aperture 28 opening to a tube 29 extending into the cap between the tubes interstices between the grains andconvert it into vapors.

As a. means for eliminating the noise caused by the inrush of air into the mirting chamber, the ends of the tube 12 areequipped with mufilers 31 of any suitable construction and here shown as comprising a series of perforated cones 32 formed in a cylinder 33 insertible in the ends of the tube, and which cones serve to break the currents of air entering the tube so as to reduce the sound thereof. ltemovably inserted in the outer ends of the muilier cylinders are dependingair inlet pipes 34: which terminate below the burner and are flared at their lower ends. A. generating pan 35 is provided and is here shown as carried beneath the burner on the supports 8. 1

In the operation of the invention, initial generation is effected by'igniting a combustible liquid, such as alcohol, in the generating pan, the resultant flame heating the burner 5 and the vaporizing tube 16. The oil to be converted into gas or vapor is then admitted to the vaporizer tube through the feed pipe 20, a control valve and a check valve, not shown, being suitably arranged. in the feed pipe. The oil on coming in contact with the highly heated walls of the vaporizer tube and with the hot particles of carborundum within the tube is converted into vapors which are ejected through the vaporizer tip into the mixing chamber, formed by the throat l4 and the central portion of the tube 12, where they are t oroughly intermixed withair admitted through the mufliers. The mixed vapors and air are conveyed through the coupling 11 and passed through a battling screen 36disposed across the intake end of the burner 5 and thence pass out the burner openings 9 and 10 where they are ignited and burn with a blue flame. The flames from the burner openings 10 maintain the vaporizer tube and its carborundum contents sufliciently heated to continue the vaporizing operation.

By introducing the air into the mixing chamber or throat through the mufiiers the burner is rendered quiet in its operation.

When it is desired to remove the vaporizer, the nipple 17 is unscrewed from the coupling 18, whereupon the tip may be withdrawn from the aperture 13. In event the burner 5 becomes worn it can be unscrewed from the caps and another put in its place.

By constructing the'parts of pipe and pipe fittings as shown, the apparatus can be built at small cost, and the various parts may be readily replaced when necessary.

While I have shown the burner as extending horizontally, with the vaporizer tube arranged thereabove, it has been found that it will operate effectively in any position, and may therefore be inverted, disposed on end, or inclined at various angles, according to the character of the fire box in which it is installed.

Various changes may be made in the details of construction without departing from the spirit and scope of the appended claims and I therefore do not limit myself to the precise form of the invention herein illustrated, forexample, the muffler may be of any suitable type other than that here shown.

It is to be observed that the oil is fed to the vaporizer under pressure, as is common in kerosene gas generators and burners, in order to obtain the necessary force to draw a sufficient volume of air into the mixing throat.
