Specification of Letters Patent.

Patented J an. 21, 1919.

:Application filed June 23, 1917. Serial No. 176,525.

To all whom it may concern:

Be it known that I, WALTER A. DORSEY, residing at J efi'ersonville, Clark county, Indiana,'and being a citizen of the United States, have invented certain new and useful Improvements in Burners for Hydrocarbon Fuels, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,

and gasifier.

which illustrate the preferred rm of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art.

In said drawings:

Figure 1 is a side elevation of my improved hydrocarbon fuel burning apparatus, a portion of the gasifier pipe fittlng being broken away to show the internal construction; and

Fig. 2 is a" plan view of the hydrocarbon fuel burner of Fig. 1.

This invention relates to apparatus for burning hydrocarbon fuels and is characterized by a peculiar and compact construction in which there is aconduit largely made up of pipes and the usual forms of pipe fittings connecting different pipe sections. An exception to the usual pipe fittings referred to is one cast as an integer and which is used to connect a portion of the conduit through which liquid fuel flows with a subsequent sub-division of the conduit provided for the passage of gas. This novel pipe fitting I have termed a gasifier since, in addition to having tubular inlet and outlet conduit portions, there is an enlar ed interyen1ng gas generating chamber portlon in which the liquid fuel is converted into gas.

He'at-conveying-and-radiating packlng is retained within the combined pipe fitting Such packing conducts heat applied to the chamber wall to and through the liquid fuel supplied to the gaslfier and to the resultant gas in such manner as to invade the entire density of the liquid and gas present in the complete gasifier pipe fitting. The chamber portion of this pipe fitting 1s also fashioned to form a flame spreader.

Part of the liquid fuel piping penetrates and passes directly through a priming pan whic displacement.

Such additional features as become apparent hereinafter are, of course, integral parts of this invention.

Referring specifically to the drawings, 1 represents a circular priming pan, the annular upstanding wall of which is diametrically perforated for the passage of a pipe section 2. Pipe length 2 projects beyond opposite sides of priming pan 1, at the left passing through and beyond a boss 3 integral with the main pan portion. Threaded onto this end of pipe section 2, and so as to bear against the boss 3, is an elbow 4 into which is screwed a vertically extending pipe length 5.

To the opposite end of pipe length 2 is screwed a reducer 6 receiving in its smaller portion a pipe 7 of reduced diameter. Pi e is connected to a pipe line 8 by means 0 a union 9, said pipe line containing a control valve 10 and extending, as shown in dot and dash lines, to a fuel supply tank, a part of which is indicated in dot and dash lines at 11.

is interlocked with the piping against tween elbow 4 and reducer 6, which prevents its displacement longitudinally of pipe length 2. Said priming pan 1s also kept from relative rotary displacement with reference to the pipe 2 by any suitable means, such as a pair of set screws 26 which pass through boss 3 and bite pipe length 2.

Parallel with, but of shorter length than, pipe section 5 is another pipe 12 connected by an elbow 13 to a horizontally disposed pipe 14, which in turn is connected by elbow 15 to a nipple'or short pipe'length 16, onto which is screwed a burnercap 17. The piping extending from tank 11, which includes pipes 8, 7, 2 and 5, constitutes a supply line for the liquid hydrocarbon fuel,

while pipes 12, 14 and 16 are included in ting 18 has the outer terminals of its tubular conduits 19 and 20 deflected or bent to receive the upper ends of pipes 5 and 12, and the intervening chamber portion 21, with which the inner ends of said conduits 19 and 20 are integral, is preferably of cylindrical contour, the bottom wall of the chamber forming a flame spreader.

Pipe fitting 18 is also a gasifier, the intervening chamber 21 and the conduit portions 19 and 20 being filled with heat conducting and radiating permeable packing 22, as shown in the broken away portion of Fig. 1. Such packing may comprise metal particles that are distributed from end to end of the gasifier pipe fitting 18 and are retained in place by screening, shown at 23, at the outlet of gas conduit 20, it being understood that similar screening is present at the inlet of conduit 19.

It being desired to use the oil burner, valve 10- may be opened to a suitable degree, whereupon hydrocarbon fuel will flow from tank 11 through pipes 8, 7, 2 and 5, entering and passing through the gasifier pipe fitting 18 and continuing by way of pipes 12, 14

and 16 to burner cap 17, from which it escapes to fall into priming pan 1. Pan 1 contains asbestos or other wick substance 24:, and after sufficient fuel has been allowed to accumulate in the priming pan 1 it may be ignited to primarily heat the gas generating chamber 21.

The liquid fuel entering chamber 21 will thereupon beconverted into gas which will pass-out through gas conduit 20 of the cast fitting 18 to find its way to and be emitted from the cap burner 17, becoming ignited from the flame that arises from the priming The liquid fuel now being converted into gas, no more liquid will flow into primingv pan 1, and that which was first introduced into such pan will be consumed, ignited gas alone then being applied to the generating chamber '21. Such gas flame is spread by the bottom of the chamber and the heat therefrom is conveyed through the metal particles to extend through the internal passages in conduit portions 19 and 20 of the unitary gasifier pipe fitting, as well as throughout chamber 21. The liquid being' fed to gas generating chamber 21 is therefore preliminarily heated throughout the density of its volume preparatory to enter ng the generating chamber 21, where it is more readily vaporized, and the vaporization is maintained superheated by rea son of the heat conduction through the particles in the as outlet conduit 20.

There is llttle likelihood of any of the particles of the permeable packing 22 escaping through the screening 23 at the outlet of conduit 20, especially when the packing is composed of iron borings about the size of peas,

iaemea but should there be metallic dust therefrom or other impurities they will be checked by screening 25 in the burner cap 17. Therefore, the outlet gas port in cap burner 17 will be prevented from becoming clogged.

It is obvious that to prevent any danger of the liquid fuel overflowing the priming or preheating pan 1 during the preliminary.

heating stage, valve 10 may be closed after sufiicient liquid is admitted to the pan. After the pan-contained liquid has been ignited, the chamber 21 becomes sufliciently heated to convert liquid fuel accumulated in the bottom of said chamber. into gas, which will signalize its own presence by issuing from the orifice in burner cap 17, establishing a visible flame. Valve 10 may then be opened and regulated to give the desired flame.
