Specification of Letters Patent. 5 nppneation'aiertgye,1912. serial No. 694,724.

ing novel means whereby regulation andk control of the supply of gas and air is el'ected, and proper mixing thereof 1s attalned.

Another object of the invention is to pro-'v vide a gas burner having improved operating means wherebyv the gas burner ismoved into and out of operative position and isk held in operative position, and furtherob jects of the invention will lbe more fully described and claimed hereinafter. Referring to the accompanying drawlngs forming part of this specification, Figure -1 is a sectional elevation showing a gas burner constructed and arranged in accordance with my invention as applied for use on a hot blast store. Fig. 2 is a transverse section on the line II- II Fig. 1, showing a detail of the gas and air conveyer and the grid or damper by which the supply of air mixed with the gases is regulated and controlled. Fig. 3 is a sectional end elevation of the gas )burnerand the branch pipe or conduit through which gas is supplied to the burner, taken on the line III- III of Fig. 1.

In the drawings 2 designates a horizontally extending tubular gas conduit which is rotatably mounted in the vertical branch pipe 3 by which the gas conduit 2 isconnected to the gas box 4. An opening 5 in the side wall of the conduit 2 adjacent to its closed rear end connects the` interior of the conduit 2 with the branch pipe 3. The plate 6 removably secured on the outer end of the conduit, by engaging with the branch pipe 3, prevents lengthwise movement of the conduit 2 relative to the branch pipe. "The upper end of the branch pipe 3 is. provided with a cap 7 to secure the conduit 2 in place thereon and the flanged lower end of the pipe 3 is bolted to the flanged outlet 8 on the gas box 4. The gas box '4 *lis connected in the usual manner with a branch pipe (not shown) leading from a gas main, gas Hue, or other source ofl gas supply, and its construction notl forming a partof this invention, the gas' box 4 will not` be further described.

The closed rear end of the gas conduit 2 is provided with a tianged branch 9, and a.

lever 10 on the branch 9 provides a convement means for turning orrot-ating the tubular gas conduit 2 in the supporting pipe Patented May 13, 1913.

`be movable' relative to the conduit 23 and movableintoand out ofpositionwith re.

spect to the gas inlet- 18 on the hotblast t stove 19 or otherl device to which the gas burner is applied for use. A stop 20 is provided on the track.' support 14- and a pawl 21 pivoted on the shaft or axle'22 Vforthe track wheelsl is arranged to vswing and bring its outer end into engagementwithk the. stop and hold the .nozzle 23 in its 'extended position when the burner is in use.

22v aiiords means for moving the pawl 2 1y on this axle 2 2 into and out of engagement with the stop20. Lu s or ears 24 on the nozzle 23 and-on the lower 'section of the split branch pipe 25 are employed to form bearings for the axles 22.

The gas and air conveyer forming part` secured on the opposite side of the gas and` air conveyer frame. The ybranch Vpipe 25. Y

95. The hand wheel 37 on one end of one'axle. A

preferably is split lengthwise into sections, as shown, to facilitate the assembling of the apparatus. Between the horizontal openings 26 in the mixer frame are transverse slots or openings 28 which open at each end through the sides 29-29 of the frame of the gas and air conveyer and which also open on the front side 30 into the nozzle 23 of the gas and air conveyer.

Mounted on opposite sides of the gas and air conveyer so' as to be vertically movable, are grids 31 having a series of slots 32 therein arranged to register with the slots or openings 28 which are adjustably held in place by means of an adjusting screw 33 having a hand wheel 34 on one end thereof. The screw 33 ext-ends through the cross arm 35 by which the upper ends of the grids 31 are connected and held in position against the sides of the gas and air conveyer frame and its lower end bears on the top of the mixer frame so that by turning the hand wheel 34 the grids 31 will be raised or lowered to move the slots 32 relative to the openings and vary the size of the air inlet openings leading into the gas and air conveyer frame. A cross arm 36 is also employed to connect the lower ends of the grids 31 and maintain the grids in alinement.

The gas and air conveyer and its nozzle 23 is pushed or moved manually on the track rails 15 into and out of position in front of the gas inlet 18 on the stove 19. The branch pipe 25, (as will be seen in Fig. 1) telescopes on and moves horizontally relative to the conduit 27 the gas and air conveyer and its nozzle 23 moving with the branch pipe 25 on the support 14.

The operation of my improved gas burner is as follows: When applied to a hot blast stove the door 38 closing the gas inlet 18 to the stove, when the stove is on air is unfastened and is moved away from in front of the gas inlet 18, as shown, the door being suspended by an arm 39 having wheels 40 on its upper end from the track 41 secured on the side of the stove. The burner is then moved forwardly manually on the supporting ways 15 to bring the nozzle 23 in position in front of the gas inlet 18 on the stove.' The hand wheel 37 on one shaft 22 for the track wheel 16 is then turned to move the pawl 21 into engagement with the stop 20 to held the nozzle 23 of the burner in position in proximity to the gas inlet 18 on the stove. The gas rises from the gas box t upwardly through the branch pipe 3 into the conduit 2 and passes out of the forward end of the conduit into the chamber 27 connecting the gas burner with the gas and air conveyer. The gas then passes through the series of parallel openings 26 in the gas and air conveyer into the nozzle 23 of the gas and air conveyer, where the gas is mixed with the entering air. Air' is drawn through the openings in thc opposite sides 29 of the gas and air conveyer into the ser' ries of parallel air inlets 28 which are arranged to alternate with the gas openings 26 in the gas and air conveyer and passes from the inlets 28 into the 'nozzle 23 of the gas and air conveyer where it is thoroughly mixed with the gas. The mixture of gas and air then passes from the nozzle 23 into the gas inlet opening 18 in the stove where it becomes ignited and is burned. The grids 31 on the sides of the gas and air conveyer are moved relatively to the gas and air conveyer by means of the hand wheel 34 to regulate the volume of air admitted into the gas and air conveyer and the hand lever 10 on theI closed end of the conduit 2 is moved to rotate the conduit in the pipe 3 forming the support therefor so as to vary the size axle 22 for the track wheels is then manipulated'to lift the pawl 21 out of engagement with the stop 20, and the nozzle 23 of the gas burner is moved backwardly until again in the position shown in the drawings. The door 38 is then moved until it is again in front of the gas inlet 18 on the stove 19,

in which position it is bolted or otherwise secured.

The advantages of my invention will be apparent to those skilled in the art. The apparatus is simple and is easily kept in repair. By its use the mixture of air and gases is'readily changed as is found necessary or desirable and the gas burner -is quickly moved into and out of position in front of the stove or other device to which it is applied for use.

Modifications in the construction and arrangement of the parts may be made wit-hout departing from my invention. Although the apparatus is shown appliedfor use to a hot blast stove it is also adapted for use in furnaces of boilers and kilns and with various other devices.
