LEWIS It. FEHR, OF COLUMBIA, PENNSYLVANIA.
SMOKE-CONSUMER.
To all whom 'it may concern:
Beit lrnown that I, Lnwis R. FEHR, a citizen of the United States, residing at Columbia, in the county of Lancaster and State of Pennsylvania, have invented a new and useful Smoke-Consumer, of which the following is a specification.
YThis invention relates to smoke consumers particularly designed for use in connection with boilerfurnaces` and the like, the object of the invention being to provide means whereby unconsumed products of combustion can be directed from the smoke box back either to1the fire box or to the ash pit, where said products are consumed, the said products when directed into the ash pit, constituting means for producing an increased draft within the furnace.
'With'the foregoing and other objects in view which will appear as the description proceeds the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.
In the accompanying drawings, `the preferred form of the invention has been shown.
In said drawings r-Figure 1 is a view partly in'longitudinal section and partly in elevation of the present improvements applied to a locomotive boiler furnace. Fig. 2 is an end elevatio-n of the furnace and the parts applied thereto. Fig. 3 is a section on line A-B-Fig. 1. Fig. 4 is a section on line C-D Fig. 1. Fig. 5 is a perspective view of the draft controlling damper and adjacent parts. Fig. 6 is a view partly in frontV elevation and partly in section of the improvements applied to a stationary boiler. Fig. 7 is -a side elevation of the parts shown in Fig. 6.
Referring to the gures by characters of reference l designates a boiler having a fire box 2 communicating through flues 3, with a smoke box 4. A hood 5 is mounted within the smoke box and above the outlet ends of the flues and is so positioned as to receive the products of combustion as they rise upwardly from saidflues. A pipe 6 extends Specicaton of Letters Patent.

from the upper end of this hood and above the boiler, said pipe terminating in a rearwardly projecting nozzle 7 housed within a drum 8. Said drum communicates, through apipe 9, with the casing 10 of a fan 11, said fan having an air inlet 12 provided with a suitable damper 13. Drum 8 has a reduced or tapered end 14 into which the nozzle 7 discharges and a pipe 15 proj ect-s from this reduced end 14 and opens into a mixing drum 16 mounted above the boiler 1. From this mixing drum extends a pipe 17 opening into a stack 18. This stack has an outlet hood 19 at its upper end and a damper, such as indicated at 20, may be interposed between pipe 17 and the outlet 19 so as to prevent the escape of products of combustion upwardly through the stack. The lower end of the stack 18 opens into a casing 21 mounted on a base 22 provided with spaced openings 23 and 24. A pipe 25 extends downwardly fromthe opening 23 and is adapted to discharge into the upper portion of the fire box 2 while another pipe 26 extends downwardly from the opening 24 and is adapted to discharge into the ash pit 27. A flap damper 28 is mounted on the base 22 and is adapted to be operated by a crank handle 29, this damper being shiftable so as to close either of the openings 23 and 24 and thus control the direction of movement of the products of combustion. A damper 80, of any desired type, may be located between the pipe 17 and the casing 21, this damper operating to prevent the passage of combustion products to the casing if so desired.
The smoke box 4 has a stack 3l extending upwardly therefrom as ordinarily and an air inlet pipe 32 opens into pipe 9 and has a damper 33, this pipe 82 being provided, at its upper end with a pivoted` hood 84 from which a vane 35 extends so as to constantly hold the hood with its inlet opening in front when the locomotive is traveling.
In using the structure constituting the present invention, the fan 11 is set in motion, a belt being preferably provided for this purpose, said belt being driven by a suitable motor, not shown, and being mounted on a pulley 36 connected to the shaft of fan 11. An air lblast will therefore be discharged into the drum 8 and directed into the pipe controlled.
15, this blast setting up a suction through pipe 6 from hood 5 and causing unconsumed products of combustion to rise directly into the hood and the pipe 6 and thence to nozzle 7 from which they will be drawn into the pipe 15. The combustion products, and the air will be thoroughly mixed within the drum 16 and will then flow through pipe 17 to stack 18 and thence downwardly into casing 21 provided damper 30 is open and damper 20 is closed. Should it be desired to discharge the combustible mixture directly into the fire box, the damper 28 is shifted so as to uncover opening 23 and said mixture will therefore flow downwardly through pipe 25 into the fire box. By shifting the damper so as to uncover opening 24, the combustible mixture will pass downwardly through the pipe 26 and into the ash pit from which said mixture will ow upwardly through the grate and into the bed of fuel. Lighter gases produced by combustion within the furnace will fiow past the hood 5 and be discharged in the usual manner through stack 31. By closing the damper 30, the products of combustio-n can be caused to flow outwardly through the stack 18. 1f the boiler isv moving, as when on a locomotive, the fan 11 need not always be employed as the hood 34 can then receive air as the boiler moves forward, this air passing through the various pipes as before described.
If desired, the drum 16 can be surrounded by a casing 37 having an inlet 38 and an outlet pipe 39 whereby water may be directed into the casing and withdrawn therefrom, the products of combustion, when passing through the drum 16, serving to heat the water, which can thus be used for any purposes desired. Referring to Figs. 5 and 6 it will be seen that the boiler is indicated at 40 and the fire box at 41, there being a smoke stack 42 extending upwardly from the boiler and having a damper 43 therein whereby the escape of products of combustion may be A pipe 44 extends from the stack 42 at a point below the damper 43 and opens into al drum 45 similar to the drum 8 hereinbefore described, there being a damper 46 within the pipe 44 for co-ntrolling the passage of gases to the drum 45. This drum has a tapered end, such as indicated at 47, and said end opens into a pipe 48 designed to convey gases to one end of a mixing drum 49 opening into a valve casing 50. This casing is similar to the casing 21 hereinbefore described and has a flap valve 51 therein corresponding with the valve 28, this valve serving to close communication between the casing 50 and either of two outlet pipes 52 and 53 extending from the casing. The pipe 52 opens into the ash pit 54 of the furnace while the pipe 53 opens into the re box. It will therefore be seen that by manipulating valve 51, the air current passing through drum 49 can be directed either into the ash pit or into the fire box of the furnace. The drum 49 is surrounded by a water jacket 55 having an inlet 56 and an outlet 57 whereby the products of combustion, within drum 49, can be utilized for heating water to be used for any purposes desired.
A fan casing 58 is supported adjacent the boiler and has a pipe 59 for directing air therefrom into the drum 46, there being a damper 60 for controlling the passage of air from the casing 58 to the drum 45. The fan within the casing can be driven in any suit-A able manner, as by means of abelt 61 mounted on a pulley 62 secured to the shaft of the fan.
It will be seen that in this type of structure the products of combustion can be'.`
thoroughly mixed with the pure air by closing damper 43 and directing a current of air from the fan casing 58 into drum 47 where the air and the products of combustion commingle and pass into the mixing drum 49. From this drum the mixture is directed either into the ash pit or into the re box.
The nozzle 7 is held properly centered within the drum 8 by a spider such as indil cated at 7 and the nozzle is similarly supported in the modified structure disclosed in Figs. 6 and 7.
Vhile the mixing drums and water jackets have been illust-rated outside of the furnace and boiler it is to be understood that, if preferred they can be'located within the fire box. This arrangement is so obvious that illustration thereof is not deemed necessary.
Although a fan is preferably employed for forcing an air current into the apparatus when used in connection with a stationary boiler, and can also be provided in connection with a locomotive boiler or the like; and although the current set up by the movement of the locomotive boilerv can be utilized for effecting a desired mixture of air and combustion products, it is to be understood that any other means desired may be employed for producing a circulation of air through the apparatus.
What is claimed is movably mounted within the casing andA adapted to close either of the openings, a pipe opening into the casing, a valve for controlling the passage of air from said pipe The combination with a furnace, of a cas-V and into the casing, a hoodmounted within the smoke box of the furnaceand above the outlet ends of the furnace flues, a pipe extending from the hood and above the furnace, a nozzle formed by the end of said my own, I have hereto ai'iXed my signature pipe, e drum surrounding the nozzle and in the presence of two Witnesses. opening into the valved pipe, and means for directing pressure into the drum to mix with JW LEWIS R' FEHR 5 the combustion products discharged from Witnesses:
