INTERNAL-COMBUSTION HEATER.

Specification of Letters Patent.

Application filed June so, 1915. Serial nojsveoz.

To all whom it may concern:

Be it known that I, CARL S. FRANK, a citizen of United States, residing at'Wichita, in the county of Sedgwick, State of Kansas, have invented new in Internal-Combustion Heaters, of which the following is a description.

My invention relates to new and useful improvements in internal combustion heaters for stoves, furnaces, grates, or the like and more particularly to that class adapted for burning hydrocarbon gases .and gas from alcohol, and my object is to pro vide a plurality of pipe sections for the reception of the liquids and gases, and inclose the same in a suitable housing'whereby the entire mechanism may be readily introduced into the fire box of a stove or other convenient point.

A further object is to provide gas jets and so arrange the same that they will convert the liquids into gases while passing through the pipe sections.

A further object is to provide suitable expansion chambers to receive and store excess gases.

A furtherobject is to provide suitable ventilating openings for the pipes and burners. And a further object is to provide a generatingchamber for pipe sections previous to admitting the gas pipes.

Other objects and advantages will be hereinafter set forth and more particularly pointed out in the accompanying specification.

In the accompanying drawings which are made a part of this application, Figure l is a top plan view of the heating device with the cover therefor removed, and Fig. 2 is a vertical longitudinal sectional view there through as seen on line 2, 2 of Fig. 1

Referring to the drawings in which-similar reference numerals designate" corresponding views, 1 indicates a housing which is preferably rectangular in general outline and constructed of sheet metal, said housing having a removable cover 2, said cover havw ing depending flanges 3 which engage the upper edge of the housing and hold th and useful Improvements the casing inclosing generating fluid into the parts throughout the several- I thereto which leads cover in suitable point within the housing 1 and above the lower edge thereof is a partition 4, which partition. is supported on suitable Patented-Feb. 22, 1916.

position thereon. Positioned at a brackets 5 carried by the Walls of the housing, said partition being spaced from the walls of the housing to provide air pas-.

sages 6, said air passages entirely surrounding the partition. Resting upon the partition 4 and adjacent the longitudinal edge thereof are tubes 7, at both ends and are adapted to be used as storage tanks for the gases, said tubes having pipe sections 8 connected therewith, the upper endsof said tubular retort chamber 9 which is preferably positioned adjacent the upper edge of the housing 1 and substantially in line with the longitudinal axial center thereof and midway between the tubes 7. The tubes 7 and pipe sections 8 form supports for the retort chamber. 7 I

The retort chamber 9 is provided with cross heads 10 and immediately below the cross heads are burners 12, the tending into the pipe 13 ofthe burners exretort chamber 9 at points beyond the cross heads 10, the upper ends 14 of the pipes 13 projecting through the retort chamber to a point adjacent the upper wall surface thereof'so as to prevent the gas producing fluid from entering said pipe should an unusual quantity of the fluid be entered into theretort chamber. The ends 15 of the pipes 8 arelikewise extended upwardly a distance above the lowermost surbut said ends 15 face of the retort chamber are not extended as high as the ends 14, so that should the gas producing fluid be entered into the retort chamberfaster than it is converted into gas, it will flow into the said tubes being closed positioned the tip ends 11 ofpipe sections entering a tubes 7 before reaching the top of the ends 14. The gas producing fluid is conducted into the retort chamber 9 through a feed.

pipe 16 which terminates in a T-head 17 beyondthe wall of the housing 1, one terminal of the T-head having a pipe 18 attached to any form of supply tank (not shown), a valve 19 being em ployed to control the flow of the fluid into I the feed p p The opposite terminal of the T-head has an extension pipe 20 attached thereto which extends through one wall of the housing and into position over a generating pan 21, said pan being formed by depressing, a portion of the partition l, preferably at the longitudinal center of the partition, so that a quantity of the gas producing fluids may be entered into the pan and ignitedto properly preheat the retort chamber 9 previous to admitting the gas producing fluid into the retort chamber.

In order to retain the iiuid'in the generating pan and prevent rapid consumption thereof when ignited, a sectionof asbestos 22, or other non-inflammable porous substance is placed into the generating pan which absorbs the fluid and causes the same to burn slowly. The admission of the fluid through the extension pipe -20 is controlled through the medium of the valve :23 intersecting the extension pipe 20 beyond the end of the T-head 17 The number of cross heads 10 and burners 12 is determined by the size of the space to be heated as but one burner may be used or any number thereof used. It will also be understood that all the burners may be provided with a controlling valve 24, although in the present lnstance, but one, of the burners is shown supplied with a valve.

The partition 4L is provided immediately below the burners with draft openings 25 and the side and end Walls of thehousing are likewise provided with vents 26 through which air may enterthe housing and cause proper combustion of the gases below the retort chamber, these openings also allowing for expansion of the gases as well as the proper mixing of the air to complete the combustion.

In order to allow for the sudden expansion of the gases above the burners, the top of the cover 2 is bowed upwardly, as shown at 27 and said bowed up portions are provided with openings 28 and29 which are arranged in series, any preferred number of,

the openings being employed.

In operation thevalves 19 and 23 are opened and a quantity of gas producing fluid admitted into the generating pan 21 when the valves are again closed and the fluid ignited in the pan. The heat from the burning fluid will superheat the retort chamber 9 and when the gas producing fluid is introduced thereinto will convert the same into a gas so as to cause the same to flow through the burner, and when ignited at the tip end of the burner the flame therefrom will continue to generate gases so long ,as the valve 19 is open. and the fluid entered into the retort chamber.

By elevating the-ends of the various pipe sections entering the retort chamber to a point higher than. the lowest level of the retort chamber, the fluid entered intothe, retort chamber will. be converted into gas 1 before it reaches a height to enter the ends of the pipes under all ordinary circum-' stances and by providing the tubes 7"the gases, if produced faster than consumed, will enter said tubes and compress therein, thereby storinga 1 sufficient amount of the I gases to cause an even pressurethrough theis positioned, and also byprovidingthe, va.-

rious openings and'vents, the proper amount. of air will be entered into the housing to cause proper combust onof the gases, and 1twill likewise be seen that this devicevcanbe used in connection. withany suitable form of furnace, stove, or other heating apparatus, or can be set up and used independently thereof if desired.
