Application filed February 16, 1926. Serial No. 88,526.

My invention relates to oil burners and has for its object to provide a new and novel means of burning oil for fuel wheredifiused heat is required.

A further object is to provide anoil burner designed and constructed to improve combustion by first changing the oil to a gas and before ignition, and to make a soft, difl:used

hydrocarbon flame whereby complete combustion of the gas is obtained with practically less air than has heretofore been required.

A further object is to provide a burner which will economically and efiiciently burn the cheaper grades of oil fuel giving off an intense heat with little cost.

These objects I accomplish with the device illustrated in the accompanying drawings in which similar numerals and letters of reference indicate like parts throughout the several views and as described in the specification forming a part of this application and pointed out in the appended claims.

In the drawings in which I have shown the best and most substantial embodiment of my invention, Figure 1 is a vertical longitudinal section of the burner with parts shown in elevation; and Figure 2 is a rear view of the burner.

The device consists of a frusto-conically shaped generator A, in which the fuel oil is vaporized and generated into a gas. The said generator A consists of two spaced apart frusto-conically shaped members 1 and 2 5 which are fastened together at one end by an annular plate 13 to form a hollow tubular gas chamber. The other end of each of the members 1 and 2 is welded to outwardly flanged members 3 and 3 which are welded together to form an extension member B to allow for expansion and contraction of the metal of which the generator A is made, when it is heated and then cools during use. The interior of said generator A is the combustion chamber. The oil is introduced into the said gener'ator'A through an oil pipe 4 which is secured on the upper side of the generator and near the nozzle end. A regulating valve 5 of any of the conventional types is connected at the other end of the said pipe 4 and controls the amount of oil introduced into the interior of the generator and is connected with the supply pipe 6 of the oil supply or reservoir, not shown in the drawings. At the other end, and on the opposite side of the generator from thepipe 4:, I provide a pipe 7 which is welded. to an upright pipe 8 at right angles to the pipe 7 The extreme end of the pipe 7 is closed with the cap 9, and the upper and lower ends of the pipe 8 are closed by the capslO and 11,

so that the pipes can be cleaned at anytime I when it becomes necessary or desirable. A burner et C is secured to the inner side of the pipe 8, at rightangles thereto, and about centrally located as to the large end of thefrusto-conlcally shaped generator VA. A. preheater of any of the commonly used gas burners D is providedcdirectly under the generator A for preheating the oil when the burner is to be started. p

The operation of my device is as follows When it is desired to start the burner the gas preheater is lighted and the oil is turned into the generator A in sufficient qua-ntity'to partially fill its interior. The heat from the gas burner D will expand and vaporize the oil in the generator and form a gas which will be forced from thejet C by'expansion and will be lighted by the flamefr'om the preheater below it. The oil is then turned on in the valve 5 inthe quantity desired and the generator continues to vaporize the oil forming a gas, a small portion of which'is in turn burned in the interior cone-shaped burner, the balance being forced into the a combustion chamber of the burner to be heated, giving a diffused hydrocarbon gas flame.

Having thus described my invention I de sire to secure by Letters Patent and claim 1. An oil burner comprlsingjtwo frusto conically shaped members spaced apart and one within the other with the ends sealed; an expansion joint in one end thereof; said expansion joint consisting of a flange on the inner frusto-conically shaped member at 2. An oil burner comprising a frustosmall end of the generator; means to direct conically shaped generator having spaced oil to the interior of the generator; and a apart side. Walls; an annular seal plate on jet to fire a portion of said oil when it has 9 the ends of said side Walls; an angled flange been generated into a gas.

on the end of the outer side member of the In testimony whereof I have afliXed my generator, and sealed to the contiguous seal signature. plate to provide an expansion joint at the MITCHELL CARTER.
