7 Claims. (01. 15a-1o4) This invention relates to gas burners particularly of large sizes for use in industrial ovens, this type of burner usually being in the form of a long manifold having a considerable number of tips projecting at intervals from one side.

The invention may be applied to any of the principal types of gas burners, either atmospheric, employing a simple mixer at the intake end of the 'manifold; low pressure, in which the air and gas are introduced by a blower; or high pressure, where the pressure of gas entering the manifold is on the order of from five to twenty-five pounds to the square inch.

The invention aims to provide a burner of. the type mentioned which-will quickly and certainly ignite all the tips from a singlesource and will avoid all accumulations of gas or failure of ignition of the jet from any tip.

Although described as embodied for industrial applications, it will be understood that the principles may be readily adapted to other forms and sizes, such as domestic gas stoves.

Referring to the drawing, Fig. l is a perspective view of a single series of burners; Fig. 2 is a perspective view showing a double series of burners; and Fig. 3 illustrates a further modification.

In the form shown in Fig. 1 a manifold of tubular form is illustrated, this being connected as at 11 to a source of supply of gas and air and closed by a cap 12 at its far end.

Along one side of the manifold a number of tips or

nozzles

13, 14, of generally L-shape are let in, these being made of alloy steel, lava or other suitable material, and arranged to project a jet of gas approximately along the outer surface of the tube 10, but preferably at some inclination to the axialline of the tube. A preferable arrangement of the tips is in two rows, stag gered, and with the tips of each row inclined slightly toward the other row so that the stream of gasor the flame from each nozzle will intersect the stream from the next nozzle in the opposite row. In the arrangement shown in Fig. 1 each tip except the first and the last two pro- 45 jects its stream across the stream of the one behind it as well as across the stream of the one in front, this criss-cross arrangement very com- Y pletely insuring speedy ignition of the jet from each tip if a light is applied to any of them.

This feature is shown by the dash lines 16 indicating gas and flame paths in Fig. 1.

The normal lighting will, of course, be from beginning to end in the direction of the flow of the streams. A preferred method of accomplishing 65 this is to place a pilot light or other igniting means, such as 15, in a position to ignite the first stream or jet of the series. This first jet will then ignite the second, the second the third, and so on. Thus the flames spread very rapidly from one end of the burner to the other and the time lag is too short .to permit the accumulation of gas in dangerous quantities at any point.

In situations where it may be undesirable to have all the flames tending in one direction, a

double ended arrangement may be employed, ighating from the'middle. Such a' double arrangement is seen in Fig. 2, which illustrates a manifold 20 connected as at 21 to a source of supply and having two series of

nozzles

23, 23 and 24, 24 each series in a row, on one section, all pointing 7o toward one end and inclined toward the opposite row.

Tips

25, 25 and 26, 26 are similarly arranged in two rows in the opposite direction on another section of the manifold. In this form the igniting means 2'? is so located as to serve both series of. tips, and may conveniently take the form of a double branched pilot light- In this double ended form the principle of criss-cross jet arrangement is likewise used, as shown by the dash lines 29 of Fig. 2.

On account of the diffusion of the gas from each tip and on account of the flame spread, it is possible to'accomplish the result of my invention by such an arrangement as is shown in Fig. 3, al-

through this is less efiicient than the other two forms shown.

. In Fig. 3 a manifold 30 is illustrated only a single series of tips 33, all directed rearwardly but inclined upwardly on parallel lines, so that the fiame from the first will ignite the stream of gas issuing from the second and so on, although the paths of the outgoing streams do not intersect. In this form an igniting means 35, here conveniently illustrated in diagrammatic style as a spark gap, is placed adjacent the first tip.

Although I have herein shown and described certain preferred forms embodying the principles of my invention, it will be understood that I do not limit myself thereto, but that the invention is susceptible of being applied in other forms within the scope of the appended claims. a

What I claim is: p

1. A multiple gas burner comprising in combination'a plurality of tips adapted to project gas on successively intersecting lines, said lines form-' ing a criss-cross arrangement along the entire row of tips.

2. A gas burner comprising, in combination, a manifold" and a plurality of burner tips on the external surface thereof, said tips being so directed that the path of gas from each will intersect the path of gas from the next preceding and from the next succeeding burner tips.

3. A multiple gas burner comprising a tube, a plurality of tips in successive arrangement in two lines therealong, the tips intermediate the ends of the burner being inclined to project a jet of gas across the jets projected by their respective preceding and succeeding tips.

4. A gas burner comprising an elongated body and a plurality of series of tips mounted on opposite sides of the top thereof, the tips of each series being staggered with respect to those of the opposite series and being inclined toward the opposite series and parallel to the other tips in the same series so that each tip not at the end directs its discharge acrossthe discharges both of the previous tip and of the next tip in the opposite series.

5. A gas burner comprising a plurality of series of tips, the tips of each series being disposed successively so that the discharge from each tip impinges upon the discharge from a tip further back in the other series and also upon the discharge from a tip further along in the other series. v 6. A gas burner comprising a tube, a plurality of tips therealong in two lines spaced transversely, each of said tips being placed opposite an interval of the other line and inclined toward the other line at a point in advance of a tip and also toward an end of the tube.

7. A gas burner comprising a tube, a plurality of tips therealong, the extension of the axis of each of said tips approximately intersecting the extension of the axis of another tip, and the extension of the axis of the latter in turn approximately intersecting the extension of the axis of still another tip.
