Patented May 30, 1933 UNITED STATES VERNON S. BECK, OF WINFIELD, KANSAS GAS BURNER Applloation fl1ed-0etober 30, 1929. Serial No. 408,615.

My invention relates to an improvement in gas burners.

The principal object of my invention is to provide a gas burner insertible into a cast frame that is stationarily supported by the masonry of the furnace, by which means the burner may be removed for repairs, or to replace deteriorated refractory members, the removal of the burner not interfering with, or damaging, the structure supporting the same.

The further object of my invention is to provide a standard fire brick refractory element supported by the inner portions of the burner, said refractory elements being in parts, of stock dimensions, and removeably arranged, so that a defective portion may be replaced.

A still further object of my invention is to provide a burner having a primary supply of air to enter with the gas flow, and a secondary air supply passing through openings between the tubes comprising the burner and coming in contact with the combustion at the burner tube ends, by which means overheating of the burner tubes is prevented. A still further object of my invention is to provide a bafile means to control the secondary air supply through the medium of the refractory elements positioned between the burner tubes.

A still further object of my invention is to provide a rectangular jamb element of a certain depth, and, in case the masonry of the wall is of a greater depth than the width of the jamb the box-like structure in which the burner is positioned, will function as an extension for the jamb so that the combustion ends of the burner will extend past the inside surface of the wall, by which means the burner is adjustable to walls of different thickness.

These and other objects will hereinafter be more fully explained, reference being had to accompanying drawings forming a part of this specification, in which like characters apply to like parts in the different views.

Referring to the drawings, Fig. 1 is a sectional view along line 1-1 in Fi 4, looking in the direction of the arrows. Fig.

2 is an inside View of the burner. Fig. 3 is a front view of the burner, showing the manifold, with respect to the burner tubes.

Fig. 4 is an elevation showing the installation of the burner and the door enclosing the same, the burner manifold being shown by dotted lines.

My invention herein disclosed consists of a jamb 1, said jamb being securely fastened to furnace wall 2, fragmentarily shown.

Positioned within the jamb is a box-like structure 3, functioning as an extension for the jamb, as an adjustment for walls of different thickness. Note that the box and the j amb referred to are connected by means of bolts B positioned at each corner respectively, by which means the box element is rigidly positioned with respect to the width of the furnace wall. Positioned within said box is a burner element consisting of a plurality of funnelled tubes 4, said tubes being in parallelism and integrally connected at the outer ends, the inner ends being spaced apart, and having fire clay brick 5, of stock dimensions, placed horizontally therebetween, said brick loosely engaging and adapted to slide inward or outward longitudinally of the tubes, by which means the point of combustion may be spaced from the inner or nozzle ends of the metal tubes, tending to eliminate excess heatim of the tubes. I have also placed a line of fire clay brick between the outer sides of the tubing and the box, said brick also capable of sliding longitudinally with respect to the tubes to the same alignment of the first said brick, by which means the adjacent edge of the box is protected from the combustion.

The tubes of the burner are slightly funnelled at the outer side thereof, as a means of freely receiving the gas and primary air supply which enters the tube, said tube functioning as a mixing chamber. Positioned between the separate tubes are openings 6 providing a secondary supply of air, for combustion and also for cooling the tubes.

These openings ,may be controlled in size by moving the refractory elements 5 inward or outward with reference to the tubing.

Should the combustion tend to heat the tubes are lugs 7, and outward from the sides lugs 8, as a spacing means for the tubed element from the walls of the box. Securely attached to the tubed element is a manifold consisting of a plurality of winged members 9 positioned in horizontal parallelism and connected b a neck member 10, said neck and wing members being hollow, thereby functioning as a gas chamber.

Positioned on the side of the Wing members adjacent the tube element is a plurality of jets 11, outwardly extending and' being spaced apart to axially align with their respective tubes, by which means the gas is in ected through all of the tubes simultaneously.

As a means of connecting the manifold to the tube element I have placed a bolt 12 near each corner, said bolt having a sleeve element 13 thereon, which acts as a spacing means between the manifold and the tube element, said bolts being secured b nuts 14 threadedly engagin thereon. n the lower wing of the mani old is a hub 15, outwardly extending, and threaded to receive a as supply pipe 16, said pipe having a vaIve control not shown in the drawings.

Hingedly connected to jamb 1 is a door 17 having an elongated slot A positioned therein, into which the supply pipe will engage when the door is closed. As a means of supporting the door in the desired open osition a notched sector 18 pivoted on the amb, is adapted to enga e with a detent 19 on the door, by whic means the air su ply for the burner is controlled. While I ave shown and described a single unit as a burner, other units may be a joined, by which means a battery of burners may be installed, and such other modifications may be employed as lie within the scope of the appended claims; and having fully described my invention, what I claim as new and desire to secure by Letters'Patent is:

1. In a gas burner; a plurality of burner tubes, integrally connected, the tubes having spaces therebetween for a secondary air supply externally thereof; a frame in which the tube structure is positioned and means for spacing the combustion point from the inner ends of the tubes; a manifold comprising a plurality of hollow wings, a plurality of jets projecting from each of the wings as a means for injecting gas throu h each of the tubes simultaneously, the mamfold being attached to the outer portion of the tube structure, and means for rigidly attaching and spaclng the manifold.

2. A burner of theclass described comprising; a plurality of funnelled tubes in alignment horizontally and perpendicularly, being integrally connected at the funnelled ends, the opposite ends being spaced apart horizontally, and fire clay brick being positioned between and around the tube structure; a frame as supporting means therefor and loosely engaging therewith; a winged manifold, the wings having a plurality of jets, the wings being connected by a neck and laterally extending from each side thereof, and means for connecting the manifold to the tube structure so that each of the jets will be in axial alignment with the tubes respectively; and means of supplying the burner with gas.

3. A burner of the class described comprising; a plurality of funnelled tubes, each tube being a mixing chamber; means for introducing an air supply between the tubes as an additional air supply at the combustion point and as a cooling means for the tubes; a rectangular frame, and lug extensions on the tube structure as spacing means for centrally positioning tube structure within the frame; fire clay brick positioned between the horizontal rows of tubes and adapted to extend outward from the ends of t e tubes; and a manifold having a supply pipe connected thereto, the manifold arranged to inject gas into each of the tubes simultaneously.

A
