GAS GEN EBATOR AND BURNER.-

Patented July 30, 1918.

Application filed March 12,1918. Serial No. 222,038.

T 0 all whom it may concern:

Be it known that 1, JAMES E. EVANS, a citizen of the United States. residing at Los Angeles, in the county of Los An eles and State of Ualif( rniu have invented certain new and useful Improvements in Gas Generators and Burners, of which the following is a specification.

My invention relates to heating apparatus and has for its objects to provide an apparatus which may be placed in a stove or furonce for generating gas from liquid fuel and burning said gas as a fuel in said stove or furnace. 7

These and other objects I accomplish with the apparatus illustrated in the accompanying drawings in which similar letters and numerals of reference indicate like parts throughoutthe several figures 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 a substantial embodiment of my invention, Figure 1 is a side elevation of the apparatus, parts cut away, Fig. 2 is a plan view of the same. parts cut away. Fig. 3 is a transverse section on line 3 3 of Fig. 2.

The present invention is a compact apparatus which may be placed in the fire box of a stove or furnace and wherein a low grade liquid fuel such as crude petroleum, or distillate may be forced by compressed air into a gas generator wherein said liquid fuel is converted into a gas, and said gas and the required amount ofair is then conducted into. two parallel spaced burners positioned above the generator where said gas from said liquid fuel is burned, and some of 'said gas is directed into another burner positioncd beneath the generator to supply heat for generating the gas. I also provide as a part of my apparatus means to prevent the accumulation of soot therein. My apparatus consists of a fuel tank A which is operatively connected with an air pump B by means of which compressed air is proride-d to force the liquid .fuel, such as distillatc, from said tank A 'througha small pipe G into one end of the generator D. The said generator consists of a cylinder 1, which is externally threaded on one end and internally threaded at the other end. In the internally threaded end is screwed the needle valve seat 2 which reduces the flow of gas through the generator and. provides a. seat for burning to heat the generator D.

for the valve.

end of said generator is screw the valve On the externall threaded stem elbow 3. The said elbow 3 is extertl'u'eads in t is said valve stem elbow 3 and.

has the free end inclined or beveled to a. point to fit in the seat 2. The burner consists of two parallel spaced apart tubular burner members 5 which are mounted on the inverted U-shape-d supports 6, and each has a plurality of transverse saw cuts 7 therein to provide gas jets and by cutting only partially across said. members and on the outer sides'of each the gas is directed up and away from said burner members 5 in order that when the gas is ignited the flame will not injure the other parts of the apparatus. A U-shaped conduit 8 having one end opening into a divider case 9 is provided to direct the gas from said generator I) into both of said burner members 5 and break up the flow of the gas so that it will llowf'into said members 5 with but a slight curreht. The said divider case 9 is secured on one end of the said meu'ibers 5. In the other end of one of said burner members 5 is connected the pipe. 10 through which a limited amount of gas is supplied to a generator burner 11 positioned under the said generator D. The sa-id'generator burner 11' has a plurality of holes 12 in one side to allow gas to escape n asbestos mat plate 13 is fastened on said generator burner parallel therewith by which the initial heat may be provided to start the apparatus. Water is supplied through the valves 14 into said valve stemelbow 3 when desired to form steam to clean the apparatus from any accumulation ofsoot theieln.

The operation of my apparatus is as follows With the fuel provided in the tank A and air pressure supplied by the pump B, the

by the seat Qand point of the stem 4. The escaping gas will be directed through the U- sha )ed conduit 8, the divider case 9 and into the urner members 5 a'nd pass out through the saw cuts 7. The gas will be ignited by the flames from the met 13, and to continue the supply of after'the initial fuel is burned out of t e said mat 13, some of the gas from one of the burn r members 5 will be directed through the pipe 10 int the generator burner 11 an escape tln gugh the holes 12. \Vhen the gas from said holes 1.2 is in flame it will provide the heat required to continue the generation of gas 'n said generator D, Before the gas from he holes 12 is lighted the said mat 13 is turned on its axis, which is the said pipe 10 at one end and a pin 15 in the other end of said generator burner 11, to the position shown in dotted lines in Fig. 3. Should soot accumulate at any time in the apparatus it may be eradi eated by a small quantity of water supplied within the generator 1) through the \altr ll. which \vatcris turned into steam in said gen orator and mingling with the gas will rlean the apparatus of any soot.

Having thus described my invention I desire to-secure by Letters Patent and claim 2- 1. In a as generator and burner the combination o a eylindriral generator; a needle valve to regulate the How of gas therefrom; a generator burner below said generator; two spaced apart main burners above said generator; a conduit to direct the gas from said generator into said main burners; a

mat below said generator on which to burn liquid fuel to provide the initial gas' a pipe from one of said spaced apart main urners to said generator burner; and means to supply a limited amour, of water into said genorator.

2. In a as gent aim and burner the combination u? a cylindrical generator; a needle valve to regulate the flow of gas therefrom; a generator burner below said generator; two spaced apart main burners abovesaid generator; transverse saw cuts partially across said main burners; a U-shaped conduit and bifurcated to direct the gas from said genera-- tor into said main burners; a mat below said generator on \Yllltll to burn liquid fuel to provide an initial gas; a pipe connecting one of sai spaced apart main burners and said generator burner; and a valve controlled water pipe to supply a limited amount of water into said generator.

In testimony whereof I have afiixed my signature.

JAMES E. EVANS.
