Claims. (01. 158 -119) This invention relates to gas burners and it has particular reference to gas and air control especially adapted to, use in connection with gas burners in commercial the like, and its principal object resides in the provision of a combination of elementscalculated to regulate and control the introduction of fuel gasand air mixture so that an equal distributionsof both elements will be permitted to pass, into the burner to increase the heating efiiciency of the latter.

Another object of the, invention resides in the provision of such an apparatuses will maintain, at all times, regardless of the desired pressure, a proportionate mixture; of gas and air, the streams of which being directed through the apparatus in such a manner as t'o become thoroughly mixed and commingled' to produce a highly efiicient fuel.

'Still another object of the invention is manifest inthe provision of an apparatus of the character described in whichthe' operative elements therein can be adjusted with relation to each other so as to produce passages of greater or lesser openings, as desired, with the minimum amount of efiort,

Broadly, the invention seeks to comprehend the provision of a device which will completely control the introduction of fuel intoa gas burner in order that the greatest degree of efiiciency may be realized in theuse of such fuel.

While the foregoing objects are paramount, other and lesser objects will become manifest as the description proceeds taken in, connection with the appended drawing wherein-4' Figure 1 is a side elevational view of the invention.

, Figure 2 is a longitudinal sectional View of the invention, showing. the operativeelements therein and their relationship to each other.

Figure 3 isa plan view of the invention, and

Figure 4 is a cross sectional View taken on lines 4-4 of Figure 2.

In order to obtain the ciency by the use of gas as fuel, it is highly desirable to introduce a .certain amount. of air into the burner along with the gas and cause the same to be so thoroughly mixed and intermingled with the gas as to provide a more combustible fuel and it is the primary object of the herein described invention to provide a means whereby such mixture can be accomplished.

Accordingly, the invention is provided with a one end of which is open and is provided with an apertured flange highest degree of effiplants for boilers, orv

through which bolts, or similar articles-can be insertedto secure the assembly in position, as shown in Figures 1 and 2; The opposite end of the housing 1.; is closed, as, exemplified; particularly in Figure 2, and is integral with a sleeve,

or cylindrical member orgas' inlet chamber 3, the latter, having an integral annular projection, or connection 4-,shown in Figures -1 and 3-, into which the gas inlet pipe is threaded.

A plunger-f rod 5 is operatively disposed longitudinally through the member' 3, as shown in Figure 2, andis restrained from'lateral movement within themember 3 bya guide member 6; the latter beingthreaded into the end of the member 3 and which is provided with aneck portion '7, which arrangement is illustrated in Figure 2. Threaded upon one end of the plunger rod 5 is provided a substantially conical shaped control valve- 8 which operates within an orifice 10 in the bottom ofthe gaschamber or member 3, previouslyreferred to, and which will be more specifically described later. cape of gas throughthe member Saround the plunger rod '5 a packing gland is threaded into the member 6, i

As will be seen by reference toFigure 2, the upper end of the plunger rod 5 is rigidly affixed to a substantially U shaped yoke 11.

Slidably arranged within thehousing 1,' as shown in Figure 2, a substantially conical shaped member 12 is provided, the purpose of which is to regulate the influx ofair through, the device To prevent the esand will be: presently] more definitely described.

The member 12 is adjusted longitudinally within the housingl by means of rods 13' which are threaded into the uppermost side of the member 12 and extend longitudinally therefrom, through apertures in thehead 2' of thehousing 1, their outer ends extending through the apertured ends ofthe yoke 11 and secured thereto by means of lock nuts 14*and115, as shown in Figures 1 and 2.

The housing 1 is: provided with a series of elongated ports .16 arranged around the upper portion of housing. 1 in the manner" illustrated particularly in Figure 1, through which air can pass through the device as illustrated by the arrows in Figure"2'.-

annularflange 17-is arranged around the lower end of the member 12 to slidably engage the inner walls/of the housing 1 to prevent the passage of gas or air therethrough, as shown in Figure 2. v

The lower end of the gas chamber 3 is also provided with a flange 18, the latter being beveled, as illustrated in Figure 2, to conform to the converging inner walls of the member 12 so described.

i and through the chamber 3,

ber

thatuniforrnity in the annular opening 19 surrounding flange 18 between the latter and the inner walls of the member 12 can, be maintained.

The primary object of the invention, being to regulate and control the passage of gas and air into a conventional gas burner and maintain uniformity in the mixture of these elements, it is necessary that the respective passages of the air and gas be opened and closed simultaneously and proportionately with relation to each other. i

In '0 eration, therefore, when the yoke 11 is urged toward the housing 1 the plunger rod 5 is moved and, by reason of itsconnection to the latter, the conical valve Bis displaced Within the orifice 10. Due to the peculiar shape of the member 8, one end of which issmaller in diameter than its opposite end, its longitudinal movement through the orifice 10 will lessen or increase the surrounding passage within the latter as desired from' time to time. By reason of the relationship between the yoke 11 and the member 12 through the rods 13, the member 12 is moved coordinately with the member 8, as illustrated in Figure a In order'to bring about the proper adjustment of the relationship of the passage 10 surrounding the member B, and the passage 19 surrounding the flange 18, the lock nuts 14 and 15 can be moved along the rods 13, previously The gas will pass into the chamber 3 through the lateral connection 4, as shown in Figure 1, as indicated by the arrows in Figure 2, and out through the orifice 10 around the conical valve member 8 While, at the same time, air is drawn in by the passage of the gas through the apparatus through the open portions ofthe ports 16, which is also illustrated by the arrows in Figure 2. Obviously, when the yoke 11 is moved to or away from the'housing 1 both passages 10 and 19 will be enlarged or reduced proportionately and, due to the oppositely inclined surfaces of the mem- 8 and. the inner Wall of the member 12, the air and gas streams will cross each other in the mixing chamber 20 thereby insuring a constant mixture of air and gas through the device a at all times, capable of adjustment as desired.

'Manifestly, the structure shown is capable of considerable modification and such modifications as are consideredwithin the scope and meaning of the appended claims are also considered within the. spirit and intent of the invention. l
