12 Claims.

T s in entio relates to m rovements in gas burners. v

The main b ec of th s inven ion First, to provide a gas burner of the heating type which is highly efiicient in the utilization of the B. t. u.s of the gas consumed.

Se ond. to. pr vide a. a bu n wh ch may easily installed in various types .of furnaces and boilers and connected to a source of gas supply.

Third, to provide a burner having these advantages in which there is no :so-oalled primary air mixed with the gas prior to. its discharge from the burner orifices, and at the same time provides for the admission of secondary air or air at the point of discharge of the burner orifices for an efi'ective air mixture with the gas to provide efiicient combustion.

Fourth, to provide a gas burner which is of few parts and these parts are readily assembled and do not require adjustment relative to each other for difierent installations.

Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:

Fig. 1 is a fragmentary side elevation of a burner assembly embodying my invention, partially in vertical section and partially broken away,

certain parts. being shown conventionally.

Fig. 2 an enlarged. fragmentary view mainly in. vertical section.

Fig. 3 is a perspective view of the burner head.

Fig. l is a fragmentary View partially in vertical section of a modified form or embodiment of my invention.

The burner of my invention, illustrated in Figs. 1 to 3 inclusive, comprises a body member designated generally by the numeral i and having a bottom 2 and side wall 3. cylindrical lower portion .4 and an outwardly flaring upper portionfi desirably of inverted conical shape. A tubular burner head holder member 6 is cast integrally with the bottom and walls described and'has a portion 1 projecting centrally into the chamber formed by the walls and bottom. and also projecting below the bottom to provide a coupling portion & internally threaded to, receive the ga-ssupply connection 9 which is carried by the. equalizing chamber member Ill which constitutes a, base provided with supporting legs H.

The, burner head l2 isprovided with a cylin:

side wall has a drical upper portion l3 fitting within the upper end of the holder in closing engagement with, its] walls. The head member is provided with a cylindrical inner portion I4 spaced from the upper portion by an annular groove. or recess [5. The

cylindrical portion M is spaced from the wall of the holder to provide an annular gas passage It. This is desirably quite restricted to insure even distribution of gas to the recess I5.

Below the portion M, the head member has a downwardly tapering portion l'l which merges into the portion M and acts to uniformly distrib ute or guide gas to the passage Hi- In this preferred embodiment the upper edge of the head memberis beveled at l8. The gas delivery ports".

or jet orifices l9 are disposed at an angle and ct to direct the gas outwardly. The burner body is provided with a plurality of angularly spaced lon a d air .inl o ni gs 2|! desira ly ar ranged in the plane of the discharge ends (lithe je s- With this arra gement th gasis very unim v del ve d abou the burn r h ad and into i A pil t 2.! is convention- 1 the burne chamber. ally illustrated.

T a upp v'p p .2 s provided with at outo l" valve 23. with a pressure r ulator 24 at the r ar of the v lve 23. nd with a thermost tica ly c troll d. valve 25, the valve control mechani m ing c nve tion lly i lustrated at It has suitable electrical connections to a thermostat desirably located in space to be heated. The

pre s re regulator is of imp anc a i is found practical to deliver the gas to. the burner at. at, relatively l w p ssure and i is desirable o deliver it at a uniform pressure. The burner is adapted for use in connection with gas supply systemsor it may be used in connection bottled gas. The chamber in is disposed at the.

rear of the re ul r a fur h r serves 0-1 35 vide a uniform delivery of the gas to the burner;

One of the featureswhich I wish to particularly" point out is that no primary air is admitted in" dv nc f he dischar e of the gas into the) burner chamber and consequently there are no, adjustable parts which can be manipulated by. inexperienced persons to decrease the efiiciency of 1 the burner. In use the combustion takes place largely at the top and above the burner body. An advantage of this is that the burner head. does. not become substantially heatedand there is no accumulation of carbon on the head or in the-jet orifices.

In the embodiment shown in Fig. 4, the wall .21 is cylindrical throughout theburner head holder,

and the air inlet openings are the same as, de-

scribed. The burner head 28 is set into the holder with its face flush with the upper edge of the holder and the jet orifices 29 are vertical opening at the flat face of the burner head. The head is otherwise the same as that described. This structure is also effi-cient although that shown in Figs. 1 to 3 inclusive is preferred by me.

I have illustrated and described my'invention in highly practical embodiments thereof. I have ;not attempted to illustrate or describe other embodiments or adaptations which I contemplate as it is. believed that this disclosure will enable those skilled in the art to embody and adapt my invention as may be desired.
