' Y Gas BURNER.

`Application filed .Tune 1,

The invention relates to improvements in gas burners designed primarily for consuming natural gas, and the principal object of theinvention. is Vto provide axburner of this type which is extremely simple and inexpensive, yet will be ellicient and reliable Y andwill insure proper ymixture' of air and gas to attain the best results.

One of the most important uses of the burner is in connection with boilers and by proper installation, I have been enabled to overcome the diflicultiesv heretofore'prevalent, due to baking of the mud in the mud rings of boilers, which condition is the cause ofat least seventy-five per cent 'of the boiler trouble commonly encountered when gas or natural gas is used as fuel.

,Vitli the foregoing in View, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompany'- ing drawing.

Figures 1 and 2 are respectively a side elevation and a top plan View of a burner constructed in accordance with the invention.

Figure 3 is a longitudinal sectional view on line 3=3 of Fig. 2.

Figure 4 is an end elevation.

Figure 5 is a transverse section on line 5-5 of Fig. 3.

Figure 6 is a fragmentary plan view showing the preferred manner of connecting two of the burners for use with a-boiler.

The drawings above briefly described may be considered as the preferred form of construction, with the understanding however 'that within the scope of the invention as claimed, numerous variations may be made.

The numeral 7 designates an elongated burner body of trough-like form, the bottom of this body being designated at8, while 9 refers to its continuous upstanding side wall. At longitudinally spacedpoints, the bottom 8 is provided with inlet openings 10 for gas and air, and these openings are preferably surrounded by upstanding nipples 11. By preference,the bottom, side walls and nipples of the body 7 are all cast as a single unit.

Disposed at the open top of the body 7, preferably within the upper portion of the side wall 9, is a baille 12, said baffle being spaced from said wall to provide a narrow outlet 13 for the mixture of gas and air. This baile 12 is preferably in the form of a 192e. serial No'.V 113,092.

Hat cast plate, and in the preferred form of construction, is provided with'downwardly.

projecting longitudinal flanges 14 kwhich are inwardly spaced from the wall Qand in the present showing have downwardly' projectingleg portions 15 whiclifrest upon the Abotvtoni 8. The flanges 14 co-operatewith the plate 12 in checking the discharge of gas and air through the outlet 13 and consequently insure thorough mixing and heating of suchV gas and air before they are discharged for combustion.

Disposed longitudinally under the burner body 7, is a gas supply pipe 16 having outlet orices' 17 in line withthe openings 10 and nipples 11. The gas is of course discharged under pressure from the orifices 17 and as it passes throughthe openings 10 and nipples 11, it induces air to enter through said openings -and nipples, and the gas and air become thoroughl mixed under the baille-12 before they areV ischarged, as above explained.

In order to get the proper mixture of air and gas, it is necessary to consider climatic conditions and altitude, and in order that the burner may be successfully used under any conditions which may be encountered, I

provide for adjusting the pipe 16 toward and from the body 7 and by so-doing, I am enabled tofvary the amount of air entering the burner body, as occasion may dictate.

Preferably, pairs of arms 18 are secured by bolts or the like 19 to the body 7, said arms projecting downwardly from said body and engaging opposite sides of the pipe 16. These arms are provided with longitudinal slots 20, and bolts 21 pass through said slots over and under the pipe 1'6. This arrangement permits the necessary adjustment of the pipe and after such adjustment, tightening of the bolts lwill effectively clamp it and the burner body in fixed relation. The arms of each pair may if vdesired be bent from a single metal bar, as will be clear from Figs. 4 and 5.

I preferably use the burners in groups of two, as indicated in Fig. 6, and when so doing, the pipes 16 of the two burners may be connected with aV common supply pipe 22 by means of appropriate piping and connections 23.

Excellent results are obtainable from the details disclosed and they are therefore preferably followed. However, as above stated, variations may be made within the scope of the invention as claimed.
