Y a corporation of wars Application May 2, 1945, Serial No. 561,024 Claims. (01. 158-118) My invention relates to gas burners and particularly to an improvement in what is known as ribbon burners.
Ribbon burners are designed primarily to pre- In Figs. 1-3 of-the drawings, the numeral ll designates aburner head. This burnerhead is provided with a collar I: which snugly flts over an upstanding tapered neck It formed on a conventional mixing tube I 0, whereby the burner head is removably supp rted on the mixing tube.
Burner head ll comprises a casting formed with two longitudinal-branches ll connected byan integral bridge member 20. Bridge member is.
formed of .two transverse walls fla and a top wall 201; which form a transverse passage 22.- Each of the branches I8 is formed with a longitudinal passage 24 which communicates midway type burner of such construction that the ribbon may easily be made on continuous rollers and cut to any length as is needed'for a particular type or shape of burner head. In accordance with m invention, each of the individual ribbons thatmake up a set or assembly for a particular burner is of the same'shape and size, thereby greatly'facilitating the assembly of the burner. The shape and construction of the individual ribbons is such that they may be assembled in any shape burner, and when so assembled, they cannot buckle out of place. Further, the construction of my improved ribbon is such thatthe assembled ribbons are always held in the desired spaced relation in the burner head so as to insure properflow of the air-gas mixture through the burnerand substantially complete combustion of the mixture.
The above and other objects and advantages of the invention are attained as set forth in the detailed specification taken with the accompanying drawing, in which:
Fig. 1 is a top plan view of'a burner head incorporating my invention;
Fig. 2 is a side elevational view, partly in section, of the burner illustrated in Fig. 1;
Fig. 3 is a vertical sectional view taken on line 3-3 of Fig. 1;
its'length with the transversepassageli. As shown in Figs. 2 and 3, transverse passage is p in open communication with the upstanding neck ll of mixing tube It, the arrangement being such that a combustible air-gas mixturepasses rip-1 w'ardly through mixing tube (it into transverse passage 22 and from therev into/longitudinal. passages 24. The upper surface of each of the branches I8 is flat and is machinedtoqforma longitudinal slot 26 which is in opencommunication with the longitudinal passageway,"'2l ofeach-oi' these branches.
In order to properly distribute the air-gas mixture throughout the length and breadth of the slots 28, and in order to prevent 'flash-back of the burning air-gas mixture through the flash tube and to hold the flameof burning air-gas mixture on the burner head, I provide each of the slots 28 with a plurality of grooved or corrugated strips or ribbons 28, to be described in more detail hereinafter. For purposes of illustration, I have shown four such ribbons in each of the slots. These ribbons are supportedat their ends by the transverse end portions 30 of branches l8 and at their middle by a bridge member 32. The ribbons may be welded or otherwise secured at their ends and mid-portions, or they may be arranged to float lengthwise in the slots. However, because of their corrugated construction, the ribbons are free to expand and contract without buckling; therefore, I prefer to secure the ribbons in the slots.
The ribbons 28 are made of thin heat-resistant metal, and as shown particularly in'Figs. 5 and 6, are formed with vertical corrugations provided with two rows of vertically-spaced staggered diamond-shaped indentations 28a and 28b formed on opposite sides of each ribbon. The arrangement'is such that an indentation on one side of a ribbon forms a projection on the other side thereof. The indentations are formed so that, viewing the ribbon from either side, each corrugation has at least one indentation in its crest and at least one projection in its valley. As viewed from the left in Fig. 6, indentations 28a project inwardly and upwardly from the crests of the corrugations to the valleys thereoi and then these indentations project outwardly and upwardly from the valleys to the crests of the corrugations. Indentations 28b, on the other hand, produce -projections on the left side of the ribbon which project outwardly and upwardly from the valleys to the crests of the corrugations and then upwardly and inwardly from the crests to the valleys. In Fig. 5 the heavy vertical lines represent the break lines in the corrugations, the diagonal lines represent the boundaries of the diamond-shaped indentations and projections, and the central horizontal lines between the diagonal lines represent the break lines in the indentations and projections.
The number and depth of the corrugations, and of the indentations and projections are made to suit the requirements of the burner in which the ribbons are to be used. However, by forming the corrugations with a plurality of rows of staggered indentations, with at least one row of indentations formed on opposite sides of each ribbon, and with one row of indentations located closer to one longitudinal edge of the ribbon than another row of indentations is located relative to the opposite longitudinal edge of the ribbon, the ribbons may be cut to the desired length to fit a particular type of burner and may be assembled by merely turning alternate ribbons upside down. In this manner, the ribbons are held in spaced relation to form jets for the air-gas mixture, and the corrugations together with the indentations and projections provide circuitous paths of flow for the air-gas mixture from the bottom to top of the assembled ribbons as viewed in Figs. 3, 8 and 9.
The ribbons are formed by passing a strip of heat-resistant metal of a proper thickness and width through a pair of rollers provided with corrugating and indenting surfaces. Then the strip is cut to the proper length for a particular type burner. Because of the arrangement and spacing of the corrugations and of the indentations and projections, the ribbons may be cut to any desired length to fit a particular type burner,
whether the burner head be square, rectangular, round or otherwise, and the individual ribbons that make up a set for a particular type burner are each substantially identical, thereby obviating the need of a plurality of'types of ribbon I for a particular type of burner.
Various modifications and changes may be made within the scope of the invention which is not limited except as indicated in the following claims.
What is claimed is:
1. A gas burner including a burner head having an opening therein, a plurality ot-substane tially identical ribbons arranged in said opening, each ribbon being formed with a plurality of transverse corrugations, each of said corrugations being provided with indentations torming projections on the opposite side of the ribbon which substantially span the valleys of said corrugations, the projections of one ribbon being adapted to abut against the crests of the corrugations oi the next ribbon for keeping the ribbons properly spaced and for blocking straight line flow of fuel gas through said ribbons.
2. A gas burner including a burner head having an opening therein, a plurality of ribbons arranged in said opening, each ribbon being formed of corrugated sheet metal having spaced projections formed within the boundaries of the corrugations, the projections of one ribbon being adapted to hold an adjacent ribbon in spaced relation and provide circuitous paths of flow of fuel gas through said ribbons.
3. A gas burner as recited in claim 1 wherein the projections on one side of each of the ribbons are arranged in staggered relation to the projections on the opposite side thereof.
4. A gas burner as recited in claim 3 wherein the projections are arranged in rows that ex-- tend longitudinally of each of the ribbons.
5. A gas burner as recited in claim 4 wherein a row of projections on one side of each of the ribbons is located a greater distance from one longitudinal edge of the ribbon than a second row of projections on the opposite side of the ribbon is located relative to the opposite longitudinal edge of the ribbon.
6. A gas burner as recited in claim 5 wherein the plurality of ribbons is arranged in the burner opening in a manner that the rows of projections on one ribbon are located different distances from the longitudinal edges of said one ribbon than the rows of projections of an adjacent ribbon are located relative to its corresponding longitudinal edges.
