To all whom it may concern:

Be it known that I, ROBERT V. Howns, a citizen-of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Gas-Burner, of which the following is a. full, clear, and exact description.

This invention relates to burners and has for an object the provision of an improved construction which may be used in any stove or range or other appliance especially constructed for burning coal, gas, wood, or oil.

Another object of the invention is the provision of a gas burning structure wherein a heat absorbing body is provided and formed so as to loosely accommodate gas pipes whereby air surrounding the pipes may be heated before being discharged ad- 0 jacent the end of the pipe carrying the flame. A still further object of the invention is the provision of a gas burner using a combustion mixture and certain arrangement of pipes and heat retaining material whereby 5 an auxiliary supply of heated air is provided adjacent the supply or mixture of air and gas so that a maximum combustion is secured and consequently a maximum heat procured from a given volume of gas. In the accompanying drawings:

Figure 1 is a longitudinal vertical section through an ordinary coal burning stove, with an embodiment of the invention shown applied thereto. Fig. 2 is'a sectional view on a slightly enlarged scale through Fig. 1 on line 22.

Fig. 3 is a top plan view of a burner emparts of the construction. Fig. 4 is a transverse sectional view through Fig. 3 on line 4-4.

view similar to Fig. 4, but showing a slightly modified form of the invention. Referrin to the accompanying drawings by numera s, 1 indicates a stove of any desired kind, as for instance an ordinary kitchen ran e designed for using wood or coal as fue The stove has naturally .a smoke pipe 2 connected therewith so as to re- 7 move the smoke and unburnt gases from the fire chamber 3. A ate 4 is arranged at the bottom of the fire c amber 3, said grate being of any desired or usual structure for supporting wood, coal, or any desired --fuel.

bodying the invention the same being partially broken away for illustrating certain Fig. 5 is a detail fragmentary sectional 'duce an extreme Patented Nov. a, rare.

Arranged in thefire chamber 3 is a burner 5 embodying the invention which utilizes gas. as fuel for heating the stove 1-. This burner, as shown more particularly in Figs. 2 to 4 inclusive, is provided with a body 6 formed" preferably in a solid block and provided with a number of apertures 7. The material I of which the block 6 is made may vary as desired, as for instance a refractory material may be used, fire-brick being especially desirable as preferably some form of material is used which will absorb heat and thereby raise the temperature of the air passing through the openings or passageways 7'. Passageways 7 may be arranged in any desired order, as for instance in rows as shown in Fig. 2. In each of these passageways is arranged a pipe 8 of any suitable material, as for instance metal. All of the pipes 8 of a single row-are preferably connected to an auxiliary header 9 as shown in Fig. 4.

The various headers 9 are connected to the main orprincipal header 10 by pipes 11, there being one pipe 11 for each header 9. An air mixer 12, is provided for each of the pipes 11, as well as the valve 13. In mounting the tubes or pipes 8 in the passageways 7 the parts are so proportionedthat there 'will be an appreciable air space around the-pipes, and said pipes are also'of such a length as to fall short somewhat of the upper surface of the block 6 as shown in Fig. 2. [During the operation of the burner air will pass upwardly through the passageways 7 and mix with the gas emerging from they; pipes 8, said air moving somewhat as a hollow column so as to, in a certain sense, surround the flame at the lower end and thereby provide an exceptionally good mixture.

During the more or less continuous use of the burner heat will be absorbed by the block 6 and consequently .the 'airin the passageways 7 will be heated so that air at a comparatively high temperature will be supplied to the gas as it passes through pipes 8. The heating of the airwill cause anupdraft so that the air will be supplied to the gas at some appreciable ressure and thereby ro- 1 hot and intense fl zime having a higher flame temperature than the ordinary atmospheric burner, while at the same time producing perfect combustion withasmaller percentage of excess air than is ordinarily necessary. The thickness of the block 6 may vary as occasion may demand, but is preferably of some appreciable thickness so as to provide as long a passageway 7 as possible. The block 6 may be sup- 7 rest upon the grate 4 or other suitable support and may be solid as shown, or may be provided with apertures 19' as shown in Fig. 5, so that air may enter from the bottom into the open space 20, or from the sides and ends into said open space. The open space 20 is supplied with air from the usual ash pit of the stove 1 and said air passes up through the passageways 7 as the secondary air while the primary air is taken in at the Various mixers 12. This arrangement of air-inlet and associate parts permits any one mixer and any one row of pipes '8 tobe used so that all of the pipes could be used at full capacity or partial capacity,.or any one row may be used whereby there is great flexibility in the control of the heat produced.

. What I claim is:

1. A gas burner comprising a block, a plureality of apertures therein, a gas pipefitting into each of said apertures, but not filling the apertures, a supply pipe for supplying gas to said first mentioned pipes, and an air mixer for mixing air with the gas passing through said supply pipe whereby said first mentioned-pipes will discharge a mixture of air and gas, and the apertures in'which the first mentioned pipes are positioned will supply secondary air.

r 2. A gas burner comprising a block of non-combustible material having a plurality v of apertures extending therethrough, a ipe fitting into each of said apertures exten ing meagre from the bottom to near the top, said pipes being of a less diameter than said apertures, a supply. pipe for the first mentioned pipes, an air and gas mixer connected with'said supply pipe, and means directing a supply of gas to said ir and gas mixer.

3. A as burner for coal burning stoves comprising a body fitting into the fire chamber'of the st0ve,,said body having a plurality of passageways extending vertically therethrough, a gas pipe arranged in each of said passageways, extending from the bottomupwardly to near the top of the body,

said gas pipes being arranged in series, an

aux1l1ary header for each series of pipes, an independent supply pipe for each header, an air and gas mixer for said supply pipes, means for supplying gas to said mixers under pressure and a' valve for each mixer positioned between the means for supplying gas and the respective mixers, said first mentioned pipes being of less diameter than the apertures in which. they are positioned, whereby as the mixture of air and gas from said mixers passes through said ipes air will pass around said pipes an be discharged in a substantially tubular sheet from said body.

4. A gas burner comprising a solid block of refractory material having a plurality of series of passageways extending from the bottom to the top whereby when the block is heated the air in said assageways will move with some appreciabl i speed therethrough, a gas pipe arranged in each of said passageways extending from below the bottom to near the top, each of said gas pipes falling short of the top, an auxiliary header for the gas pipes of each series of passageways, a supply pipe connected to each of said headers whereby any series of gas pipes may be provided with gas, an air mixer connected with each of said supply pipes, and means to supply gas under pressure to each of said air mixers.
