.llnnlicaton filed June 18,

To all whom it may concern lie it known that l, EMMETT L. QUIGLEY, a citizen of the United States, residing` at Sisters-wille, in the county of l`yler and State of l/Vest Virginia, have invented a new and useful Gas Burner, of which the following is a specification.

This invention relates to gas burners of the type lrnown as low pressure burners.

The primary object of the invention is to construct burner of this character so that comparatively little draft will be nec essary to effect complete combustion, thereby cutting` down the amount of smoke stack usually required about one-half.

Another object of the invention is to provide a burner of this character for use in connection with the fire box of a boiler or furnace so constructed as to render it impossible to burn olf the tops of the burner tubes, thus greatly prolonging the life of the burner.

Another object is to construct a burner of this character which will generate steam quickly and hold it better with the consumption of a minimum amount of gas..

With the foregoing and other objects in 'view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure l represents a side elevation of a burner constructed inaccordance with this invention with parts broken out and in section.

Fig. 2 is a top plan view thereof, and

Fig. 3 is an end elevation.

ln the embodiment illustrated, the burner constituting this invention comprises a cast iron main burner holding` frame l preferably rectangular in form and the top and bottom bars of which are bolted to cast iron cross bars 2 and 3 which operate in connection with the top and bottom bars of the main frame to clamp the burner tubes 5 in place, the said cross bars and frame bars being recessed in their opposed faces to conform to the shape of the tubes for securely 1922. Serial No. 567,888.

clamping them in position, as is shown clearly in Fig. 2.

` rEhe end bars 4 of the main frame are extended below the bott-om bar thereof to provide legs da on which is mounted the supply pipe 6, said pipe 6 being secured to the legs by stirrups 7 which extend transversely through said legs and are held in operative position by nuts 8.

'llhegas supply pipe G is equipped at one end with a removable cap 9 while the opposed end thereof is screw threaded for connection with a conduit (not shown) through which the gasv is conducted to the pipe.

The burner tubes 5 are of a length and diameter which has been determined by many experiments to insure the formation of a proper mixture in these tubes.

Extending upwardly from the supply pipe 6 into the tubes 5, are a plurality of gas jet tubes l0, one of which enters each of the tubes 5 and is provided at its terminal with a drilled opening l1 the size of which. and the length of the tubes has been determined by experiments to insure the proper positioning of these tubes l() within the tubes 5 so that they will operate when the burner is lit to draw in air behind them from the open lower ends of the tubes 5, thereby insuring a proper mixture to produce complete combustion.

When a burner of this character is installed in the re box :of a boiler (not shown) said lire box is rendered absolutely air tight by any suitable means such as sheet iron and tire clay placed over the grate bars and around the top of the burners, excluding all air except that which enters through t-he burner tubes 5 which mixing with the gas supplied through the tubes l0, provides a highly combustible and cheap mixture.

This arrangement and mounting of the burners requires very little draft in the lire box, and hence the amount of smoke stacll: for producing such draft may be cut down to about one-half the amount ordinarily required for this purpose. This cutting; down of the smoke stack used, results in a great' saving' of time and labor in erecting boilers. particularly portable boilers, such as are used in drilling outfits and the like.

The use of the heavy cast iron cross bars at the top of the burner between which the burner ends are clamped and which extend 110 through the grate bars in the fire boX renders it substantially impossible to burn off the tops or' the tubes 5 which frequently occurs when plate iron is used for 'supporting these tubes 0r when the tubes extend up through the grate bars Without any protection.

rlhe provision of the removable cap 9 'for the gas supply pipe 6 provides for the cleaning; out of 'this pipe by reinoving said cap and blowing` out the pipe.

A burner of the class describedl comprising a rectangular supporting 'fra-me havingf the end members thereof extended below the bottom member7 a gas supply pipe mounted on theextensions of said end members, cross bars arranged to operate in oonneetion with the top and bottom bars of said frame to form burner tube clamps, said cross bars and 'frame bars being recessed in their opposed faces to conform to the shape of the tubes to be clamped between them, whereby the tubes may be readily assembled and individual tubes removed when desired, burner tubes carried by said. frame and clamp between said cross ybars with their lowerl ends'spa'eed Jfrom the supply pipe7 said tubes being open at both ends,

,gas supply pipes leading from said main gas supply pipe and extended into said burner tubesl` said gas supply pipes beingv of less diameter than the burner tubes and provided at their inner ents with nozzles discharging' into said burner tubes and operating to suck into the burner tubes air Which is combined With the gas to form a BERT ADKINS, FRED BROWN.
