GAS-STOVE T '0 all whom it may concern:

Be it known that l, l\'l.\ns.\\'e\N OBRIEN,

a citizen of the United States, residing at Lawrence, in the countv of Douglas and? State of Kansas, have invented certain new l I g p and useful Improvements in GasStoves, of

which the following is a 2, the bottom of said drum b of which is provided with depending tubes an'outer cylinder or specification. I This invention relates to certain new and useful improvements in gas heaters of that type in which is employed a heating drum, and means for causing the products of combustion and heat to take a'circuitous path so toincrease the radiation.

' The present invention has for its objects among others to provide a simple and cheap construction in which there is a plurality of concentric radiating surfaces, the'inner. one

the lower ends of which in turn are received within tubes of greater diameter,- the inlfifi' cylinder or drum being made removable a d having a cap designed to make a close fit over an annular collar or upwardly extending flange on the outer cylinder or drum. The burner is practically closed, sufiicient air for combustion being supplied thereto, the products of combustion att'er circulatin around between the drums through a central chamber and exit pipe therefrom. A door s provided to permit access to the burner or for any other purpose that may be'require'da Other objects and adi antag'es of the invention will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claim. ,9 The invention is clearly illustrated in the accompanying drawings which, with. the numerals of reference marked thereon, form a partof this specification, and in which- Figure 1 is a substantiallycentral vertical section through a heater embodying mi in vention, with the gas supply pipe n e 'ev'ation and with a portion broken away. Fig. iszncross section on the line 2-2 of Fig. 1 looking in the direction of the arrow.

ike numerals of reference indicate like parts in the diflereut views.

' Referring to the drawings 1 filesignates drum designed to bev upon suitable'supports as the legs eing closed ex cept as hereinafterspecified. At its upper end there is an annular opening 3 surround ed by the collar or fian'ge 4 extending upmounted -wardly above the top 5 of the cylinder or i Specification of Letters lEatent. Application filed February 10, 1908.

to snugly embrace the passing out 21 carryin indicated by the V J'l'rom the space between the cylinders 10 and Patented June 8, 1909. Serial No. 415,087.

drum. ln the bottom 0 of this cylinder or drum are the openings 7,'ot any desired number, in this instance shown as'three,

and from this bottom (3 there extend in \vardlythe short tubes 8, joined to the bottom (3 and at their upper ends joined to the bottom 9'01 the cylinder or drum 10 which is concentric with the cylinder 1. This cylinder or drum 10 is of less height than the cylinder 1, as seen in Fig. 1, being open at the top, as seen at 11. p

12 is'the inner cylinder. It is open at the top, as seen at 13, its bottom 14 being provided with a plurality of openings 15,

in this instance three, corresponding with the number of openings 7 in the bottom 6 of the cylinder'l, and secured in these openings are the tubes 16 which depend therefrom and extend within the tubes 8,, as seen clearly in Fig. 1. Extending outwardly from the top of this inner cylinder or drum is a flange 17 from which depends the annular collar or flange 18 which is designed upwardly extending flange or collar 4 of the cylinder 1 to make a tight joint therewith, as seen clearly in Fi 1.

1 9 is a closure, able form,

which may be of any suitpermitting access through the to the 12 to allow of reaching the burner to light it, or for repairs or other purposes.

Extending upwardly through the bottoms 6 and 9 of the

cylinders

1 and 10 is a pipe at its upper end a burner 22 of any suitable or well known type, the said pipe 21 being connected with the pipe 23 leading from a suitable source of fuel supply such as gas.

space between the cylinhe inner, ylinder or drum 1 2 with its.

tubes 16 can be removed at any time for repairs or other purposes, being lifted out by flange 18, as will-be readily understood.

In use, the gas being turned on and ignited at the burner, the course of the heat and the products OfCOmbIIStiOII will be arrows in Fig. 1 being 1;.2-upward and out 01 the open end of the cylinder 10, thence downward in the annular space betweenthe cylinders 1 and .10 and thence toward the center of the device and out through the exit 24. By this means the heat and products of con bustion are lrought into direct vontta-t-hhith all oi the cylinders and tubes andi the air which is drawn in through the tubes 8 and 16 is readily heated and the heat -is brought into direct contact with the various cylinders which greatly increases the radiation.

\Vhat is claimed as new is The combination in a heater, of an outer cylinder constructed'with top and bottom closing end portions and with openings in its bottom end, an adjacent inner cylinder provided ,With an open upper end and a closed lower end, pipes arranged depending; from the bottom of said adjacent inner cylinder, said pipes being arranged providing open passageway through the bottom of the outer cylinder and' leading into said adjacent cylinder, an innermost cylinder located in said adjacent cylinder, the innermost cylinder being constructed with 'an' open top end and a closed bottom end, and also made shorter than said adjacent cylinder, pipes with open ends arranged deleading from aforesaid holes in the atom of the outer cylinder to and into, the inner most cylinder, a burner arranged in. said adacent cylinder, said burner being located under the bottom of the innermost cylinder,

i means adapted to convey gas to the burner, the outermost cylinder being provided with i an exit opening, said outer, adjacent, and l innermost cylinders being constructed and 1 arranged providing up and down passageways therehetween, leading from said j burner to aiioresald exit opening.
