To all 'whom t may concern:

Be it known that I, ERNEST E. EISENBACH, a citizen of the United States residing at Philadelphia, in the county of lDhiladelphia and State of Pennsylvania, have invented new and useful Improvements in Oil- Burners, of which the following is a specification.

The invention relates to liquid and gaseous fuel burners and has for an Object to provide an oil burner for use in burning various kinds of oils such as kerosene and the like to derive heat.'

The invention comprehends among other features the provision of an oil burner which is particularly adapted for use in stoves and ranges, to be placed in the lire box thereof and be connected with a suitable oil supply so that the kerosene or other oil iiowing to the burner proper will'be converted into a gaseous form prior to a combustion, the ultimate combustion of the gas providing the heat with which to heat the fire box for cooking or other purposes with a part of the generated heat adapted to the further generation of new gas from the oil supply t0 the burner.

Still further the invention comprehends various improvements in oil burners ofthe characters described, over the construction of an oil burner set forth in an applicationfoi' United States Letters Patent, led by me lune 3, 1919, Serial No. 301,387, allowed under date of July 23, 1919.

In the furtherV disclosure of the invention, reference is to be had to the accompanying drawings constituting a part of this specilication in which similar characters of reference denote corresponding parts in all the views, and in which- Figure 1 is a fragmentary vertical sectional view taken through my improved form of oil burner.

Fig. 2 is a horizontal sectional view taken substantially on the line 2-2 in Fig. 1.

Fig. 3 is a vertical transverse sectional view taken substantially on the line 3-3 in Fig. 1, looking in the direction of the arrows, and

Fig. 4 is a horizontal View taken substantially on the line 4-4 in Fig. 3.

Referring inore particularly to the views I provide a base 10 which at the ends thereof is formed with suitable supporting legs 11 and which has dished out portions 12 in the nature of basins for catching any surplus oil which may iow out through one of the exits of the discharge pipe. The base 10 is formed with a central body portion 13 having a verticalbore 14 and in superposition to the base 10 there is disposed a gas dis- 'charge pipe 15 which is preferably formed 11i two sections 16 each of a tubular nature with an inner end of eachsection connected to a T-member 17, the lower end of which 'extends'into the bore 14 and has the threaded stem 18 of a bolt 19 extended therein, said bolt carrying a suitable head 20 abutting against the underside of the body portion 13. Thus the gas discharge pipe 15 is suitably positioned in superposition to the base 10 and. the free end thereof carries a cap 21 closing that end of the pipe which cap may repose upon one end of the base. The other end of the discharge pipe is threaded into an elbow 22 which in turn has a vertically curved pipe section 23 attached thereto, the latter carrying an elbow 24 which in turn has a horizontal pipe section 25 connected thereto. The pipe section 25 connects with an elbow 26 which' in turn, through the medium of a tubular connector 27 has connection with an elbow 28, the latter having a horizontal pipe section 29 connected thereto which pipesection 29 extends beneath the pipe section 25 and beyond the pipe section 23, the latter being curved slightly as mentioned, to permit of the extension of the pipe section 29, as shown. The extended end of the pipe section 29 carries an elongated elbow 30 which is provided with a nipple 31 adapted for connection in any suitable manner with a source of oil supply.

The pipe sections 16, 25, 29 lie in the same vertical plane and in the vertical plane of the base 10 and the pipe section 29 is primarily a supporting section for a combined gas deflector and burner 32, a plurality of these burners being preferably provided, one disposed over each of a plurality of discharge openings 33 formed in the pipe sections 16 which constitute the gas discharge pipe.

Each burner preferably consists of an up? per plate 34 which is provided with aI supporting loop 35 through which the pipe section 29 loosely passes and the plate 34 is suitably attached to or formed with a tubular undersection 36 forming, with the plate 34, a chamber 37 with which communication is established through the depending tubular portion 38 of the undersection 36.

By reference to Fig. l, it will be seen that the tubular portion `38 of the combined gas delector andburner v32 depends to lie immediately above the discharge opening of the discharge pipe and in .close proximity thereto, allowing sufficient space for the entrance to the chamber 27, of a quantity of air as Well as gas which flows from the dis-V charge openings of the gas discharge pipe. In the present instance I have shown the plate 34 connected to the undersection 36 by screws 39, but it will -be apparent that any form of connection can be employed, or the plate and undersection can be formed in one piece. It will be noted however that portions of the plate 34 are spaced from the undersection 36 thus roviding slots 40 at f which point the gas Will be ignited.

In the operation of the device described we Will assume that a quantity of oil is fed to the burner and passing through the pipe sections `29, 25, 23, to the discharge pipe l5, the oil Will flow out through the discharge openings 33 at which pointthe oil can be ignited. It desired the oil can be permitted to flow into the basins formed by the portions 12 of the base and thereignited, it being. primarily necessary to heat the superposed pipe sections 16, 29, 25, so4 that the subsequent supply of oil flowing therethrough, subjected to the heat, will 'be converted into a gas. The preliminary heating flame at the discharge openings of the gas discharge pipe, can now be extinguished or allowed to burn out and it Will be apparent that the gas that was formed, flowing over the discharge openings 33, Will now pass upwardly through the tubular portions 3S of the deflector and burner 32 and will be mixed Wit-h a quantity of air passing into be ignited at the slots l0 as the mixture is deflected by the plateV 34 and issues from the chamber 37 by Way of the slots. The gas ignited at the exits of the chamber of each burner Will result in blue flames of intense heat which will not only serve to additionally heat the superposed pipe sections 29 and 25 to form the required gas or fuel, but will also heat the fire =box in Which the entire burner ismo-unted so as to provide suflicient heat for cooking or other purposes.

From vthe foregoing description it will be seen that the device described is comparatively simple in construction and arrangement; thatV any number of the combined deiiectors and burners can be provided consistent With the number of gas openings in the gas discharge pipe and that various slight changes may be made from the construction set forth Without departing from the spirit of the invention, Vthe scope of which is defined in the appended claim.

Having described myV invention, I claim- A gaseous fuel burner comprising a base providing Va flash pan and having a central Vertical bore,l a discharge pipe in superposition to the ibase, aY securing element upivardlyextended through the 'boreof the base to connect With a portion oi' the discharge pipe and secure the lsame rigidly relative tothe base, a pluralityof connectedY parallel pipes in superposition to the discharge pi ne, a pipe section connecting with one of said plurality of pipes and with the discharge pipe and constituting a-support for said plurality of pipes and combined deflectors and burners carried byV one of said pipes and supported thereby in superposi-Y tion to the discharge pi e.

In testimony whereofV ailix my signature.

ERNEST E. EISENBACH.
