GAS BURNER.

Application filed April 25, 1927. Serial No. 185,516.

The invention relates to an improved gas burner somewhat similar to that disclosed in my Patent No. 1,575,633, dated March 9, 1926. The present invention provides a burner which operates much more successfully on low pressure gas than burners of prior types. Gas, pressures of 15 to 20 pounds are quite usual in industrial applications; in domestic uses, pressures may be very low, for instance three or four ounces. To simply increase the area of a gas orifice does not give satisfactory results since a large orifice tends to decrease the velocity of the incoming gas and the tendency to draw in the requisite air for a proper mixture. My device is subject to easy and quick adjustments for either use. The present device is of very simple construction and readily assembled in a locked engagement of the various elements. In my invention I employ a one piece manifold. I also use a pair of orifices at each burner with specified elements for effecting a very desirable arrangement of parts for low pressure.

purposes. The present manifold greatly improves the assemblage of burner units over that disclosed in my prior invention and for the same burner area arrangesand increases the number of orifices for more effectual operation.

In the drawings, Fig. 1 is a plan-view of my complete burner. Fig. 2 is a side view of the burner seen in Fig. 1. Fig. 3 is an end 'view of 2. Fig. 4 is a plan view of the manifold detached from the burner elements. Fig. 5 represents a sectional view taken along the line VV in Fig. 2 looking in the direction of the arrows. Fig. 6 is a sectional view taken along the line VIVI, Fig. 5, and Fig. 7 is also a sectional view taken along the line VHVH of such F 5. Fig. 8 represents a detail view of one method joining the burners together near the top thereof. F 9 is an enlarged plan view of the corner elements of a burner. Similar numerals of reference indicate corresponding parts throughout all the figures of the drawings.

Referring to the drawings; the gas enters all burners from the supply pipe 10. The one piece manifold includes the-transverse tubular element 11 and the paired side tubular elements 12 and 13. An elbow 14 connects the pipe to the tube 11. At each end of the manifold as seen at 15 and 16 are bracket supporting elements cast with the tubular manifold. Plugs 17 close the ends of the tubes. The manifold thus described is a very rigid afiair and serves as the main support for the several unit burners and serves to keep them in proper alignment and helps maintain the alignment and adjustment during periods of alternate contraction and expansion.

At 18, 19, 20 and 21 are seen integral supports for the inner burners. burner will be noted a pair of jets which include offset paired elements 1212 and 13 13 for the respective tubes 12 and 13. And in the upper face of such elements will be noted the orifices 12 12 and 13-13 These holes permit the passage of gas from the tube 10 to the particular burner each pair serves.

The burner proper comprises a base element and a top covering unit therefor. The base unit is peculiar in construction, being preferably fashioned somewhat like a four sided rectangular box including a base member provided with the four sides 23, 24, 25 and 26. Outwardly projecting or near the outer corners of the box near or at the base thereof are cast lugs arranged in pairs and of a character that they will dovetail or interlock together in assemblage; for instance, the pair of lugs 2728 on one burner will engage and grip the paired lugs 2930 of an adjacent burner; or, lugs 3132 will engage to lugs 3834 of another burner. Cast integral with the base member 22 are a pair of tubular elements 35 and 36 forming vertical double barrel tubular elements adapted to register over and above a pair of gas ports such as 1212 or 1313". It will be noted that the tubes 35 and 36 are flared at the top and bottom at 37 and 38 and that the bottom edge 38 extends only a little way below the bottom 22, while tlietop edge 37 extends for a considerable or a desired di tance above such base.

The top cover is preferably an inverted rectangular box having four side elements 39, 40, 41 and 42. The four corners 43 serve as leg supports and stand on the base member 22. Intermediate the corners 43 at the base of the sides 3942 inclusive I fashion circular or elliptical ports 44 and 45. At 46 is the central pan-like cover or base of the inverted box, flaring side edges 47 48 outwardly and upwardly project from the edges of the pan 46 and terminate in a flat rim-like portion 49 which fits as seen at 49 into the Beneath. each upper corners of the lower box; cracks such as 50 and 51 occur intermediate the upper corners 49 as long slotted gas ports.

The end burners A, B, C and D are held rigid tothe supports and 16 by means of bolts 52 which pass through holes such as 53 and screw into threaded holes in the bases of the end burners above named. All the burners are connected together by the dovetail interlock as seen at E. At the upper part of the burners is a pipe spacer 54 passing the bolt 55 to bind the parts together. The lugs 18-21 inclusive as stated support the interior boxes.

When the burner is assembled the gas enters through the main 10 to the cross tube 11 then into the side tubes 12 and 13 then through the ports 1%, 12", 13 and 13 mi King with the air as at 56then passes into the tubes and36 and from them into the chamber 57 then downwardly passing through the passages 4a and up into the chamber 58 and then out through the cracks and 51 where combustion takes place. Asbestos and the likeniay be placed in the pan 16.

A burner of this construction distributes the gas supply very evenly and draws into low pressure gas a large volume of air. lhe pairingof the jets and the flare given the tubes assist materially in securing the best results.

Such modifications may be employed as lie within the scope of the appended claims.

Having fully described my invention what I now claim as new and desire to secure by Letters Patent is 1. In gas burners, a gas manifold comprising a pair of horizontally disposed, parallel, side, tubular elements; a pair of bracket elements closing the ends of said paired tubes; and a transverse tubular unit having a gas inlet arranged intermediate the brackets and effecting communication between the tubular elements; a plurality of jets for each side tubular element arranged as aseries of paired jets, each pair of jets being positioned one on either side of the longitudinal axis of its'tubular element.

2. In gas burners as described in claim 1 and a four sided box-like element for each pair of jets having a pair of vertical tubular elements integrally arranged therein, said tubes extending a short distance below the bottom of the box and extending a greater distance up into the box, the upper and lower ed es of said tubes being flared.

in testimony whereof I hereunto afiix my signature.

PHILIP J. SONNER.
