GAS FEEDING AND MIXING DEVICE.

Specification of Letters Patent.

Patented Apr.

Application filed March 3. 1909. Serial No. 481.101,

To all who/n it may; concern:

furnaces; and it consists in the particular construct-ion, arrangement and combination of parts which will hereinafter be fully described.

The primary object of the invention is to provide a, device which is adapted to be regulated for thoroughly mixing; with air the 'gas supplied to a furnace, thereby effecting perfect combustion and materially reducing the quantity of gas required. I

Another object to provide a device whereby a blast may be supplied for directing the gas any required distance into the combustion chamber of the furnace.

A further object is to provide, in connection with'a gas burner, means for mixing air with the gas prior to its discharge into the furnace, and means for furthermixing air with the gas after it is discharged and before it reaches the point in said furnace where combustion takes place. Anda still further object of the invention is to provide a simple and inexpensive device of the character mentioned having regulating means whereby the amount of air admitted for producing or effecting perfect combustion may be readily controlled.

In describing the invention in detail, reference is herein had to the accompanying drawings, forming a part of this specification, in Which- Figure 1 is an elevation of a portion of a furnace showing a battery of devices embodying the feeding and .mixing portions of the invention applied thereto, and illustrating the damper-operating mechanism; Fig. 2 is a vertical section. of a furnace wall, illustrating the application-of the invention,

the latter being" shown in side elevation;

Fig. 3 is a section on the line 3-'3, Fig. 1; and Fig. t is a perspective view of the gasdischarge nozzle, or burner.

Referring to said drawings, in which like reference numerals designate like parts throughout the several views-4 indicatesa furnace wall in which is pro'videdxone or more gasieed openings 2 in which is fitted horizontally the cylindrical discharge end{ or horn 3 of a substantially L-shapedhollow metallic shell 4 Whose opposite or c'eiving end or horn 5 stands substantially vertical on the outer side of said wall. and has a flared or bell-shaped air-intake mouth 6. Directed horizontally through the wall of the shell t sons to stand substantially central of the discharge end 3 thereof-is a branch gas-supply pipe Twhich leads from asupply pipe 8 an has a burner or nozzle 9 upon'its end, as shown. While any propriate form of nozzle may be employed, I prefer to use a nozzle or" knob-shaped or bulbous formation having a plnraiit of.

perforations therein, as shown, such'no .ie being particularly adapted for disch the gas in different directions. its is ohvious, the shel 4 provides for the there" mixing of the air with the gas i is r charged through the nozzle, a strong draft or suction being produced for drawing air through the shell into the furnace. A damper 10 is provided in the vertical h or end 5 of the shell whereby the on. of air admitted through the latter .2 regulated.

For partially mixing the gas prcvion' its discharge from lthe nozzle. a her mixing bell 11 is provided on the pipe rectly in the rear of the shell as shown, said bell being inclined rearward, or away from said shell, and having its flared mouth 12 located .at a point suh'icieutly remote from the intake mouth 6 of the shell that the draft through the former is not percepti-,

bly. disturbed bv the iurush of air through the mouth of the labter.

From the foregoing it is apparent that a most thorough mixing of air with the gas is providcd'for by the construction described. T he damper 10 being properly adjusted, the

- necessary amount or quantity of air required for producing perfect combustion is admit-- ted. lilowever, the shell not only provides for the proper mixing oi'air with the gas in the furnace, but also for the admission of a quantity of air with such force tlr serves as a blast for directing said g desired distance into the furnace before con: bustion proper takes place.

tally through the wall of said.

The devices composing the invention may he applied to a furnace singly, or in the form ot a battery, shown in Fig. 1. In the latter case, a horizontal gas supply pipe is provided from which the pipes branch at the proper points, and the damper-spindles 14 'journaled in the shells t are preferably connected or coupled. form a common operating shaft. As a means of operating said sha ft, for adjusting the connected dampers in unison, a sprocket wheel 15 may be located thereon and said sprocket Wheel connected by a sprocket chain 16 to a second sprocket wheel 1'? mounton a suitable bracket 18, the latter being preferably mounted upon the furnace wall 1.. A crank 19 mounted on the spindle of the wheel 17 is turned for effecting the manipulation of the dan'ipers. The pipe 7 is of such length that when the nozzle 9 is applied thereto, the latter stands in the rear of the inner end of the opening '2. Thus, the admitted through the shell permitted to mix with the discharged gas prior to its ontrance 'into the furnace. the force of the blast admitted through the shell, the whole body of the gas discharged n'iay he iliz'ecled to any desired point before combustion proper is permitted.

llaring thus described my invention, what I claim as new, and desire to secure by Letters Patent,

1. The combination with a furnace wall having a hole therein, of a hollow metallic L-shaped shell having one horn ni nnn';ed horizontally within said hole and the other horn dcymnding on the outer side of said wall, a gas-supply pipe directed. horizonshell and staxulinrg central oi: said horizontal horn, a burner nozzle on the end of said pipe, a damper for controlling the admission of air through said shell, and means associated with said pipe in the rear of said shell for mixing air wit the prior to the discl'iarge of the la 1' through said nozzle.

2. The combination with a furnace wall having a hole therein, of a hollow metallic together to l l l i Further, through tally through burner nozzle on L-shaped shell having one horn mounted horizontally within said hole and the other horn depending on the outer side of said wall, a gas-supply pipe directed horizonthe wall of said shell and standing central of said horizontal horn, a the end of said pipe, a damper for controlling the admission of air through said shell, and a mixin f bell connected to said pipe in the rear oi said shell whereby a partial mixing of air with the gas is effected prior to the discharge of the lattcr through said nozzle.

the combination with a furnace wall having a hole therein, of a hollow L-shapcd shell having one horn mounted horizontally in said hole and the other horn depending on the outer side of said wall, agas-supply pipe directed horizontally through the wall of said shell and standing central of said horizontal horn, a .la.1nper for controlling, the :uhuissirm of air tl'irough said shell, and a horu-liln; mixing bell connected to said pipe in the rear of said shell and inclined away from the latter.

The combination with a furnace wall having a plurality of holes therein, of a hollow metallic L-shaped shell for each hole, one horn of said shell being directed horizontally into said hole and the other horn thereof hanging on the outer side of said wall, a gas-supply pipe directed through the wall of each shell and standing central of said horizontal horn, gas-spreading discharge means carried by the end of said pipe in the rear of the inner end o'l said hole, a damper for each shell, means for opcrati-ng said dauumrs in unison, and means associated with each supply pipe whereby the gas is partially mixed with air prior to its (llsclmi'gt. i

in testimony whereof I atlix my signature in presence of two sulmcribingwitnesses.
