Missouri, have invented .certain new and luseful Improvements `in Smoke-'Consuming Furnaces, of which the followingis a specismoke 'consuming furnaces in which the unrconsumed gases and carbon areQtaken from theexit end of .the dues, and afterbeing i mixed'with steam4 or air are passed into the .fire chamber to be consumed. A nd the pres- Vide a simple and ecient structural arent improvementfhas for its objectto pro# gangement and lcombination of parts wheresy the uncon'sumed gases and carbon are withdrawn from the exit end of the lines of a steam boiler and after being mixed with air, steam and pulverized fuel are discharged in an evenv'and uniform manner linto the re chamber of the furnace to be consumed, lall as will hereinafter more fully appear.
In the a'ccc'ii'np'anying drawings :-Figure 1,is a vertical longitudinal section of a steam boiler furnace havingv the present improve ment applied.y Fig. 2, is an irregular horizontal section on line mand -m, Fig. 1. Fig. 3, is a, detail transverse vsection on line naze-mz, Fig. A2. Fig. v1, is al detail horizontal section of the'ydischarge means to the p fire chamber."
Similar numerals of reference indicate `like parts inthe several views.
vReferring .to the drawings, 1 represents an 'ordinary horizontal steam boiler having 4return lues 42 which discharge into a forwardly arran 'ed uptake or breeching 3, as usual.4 Said oiler-is arranged above a fur ,nace or fire chamber 4.- having a bridge wall 5, as usual, A

provided-with a series of discharge tubes 14 that extend laterally' through the Wall ofl .the fire chamber to discharge 'transversely into the same in a plane above the mass of fuel carried on the 15 is a funnel or opper arranged at the upper end of the aforesaid vertical trunk 11, and adapted to contain a supply of pulverized coal, the passagel of which into the trunk 11 is controlled by a slide valve 16.
17 is an inclinedpartition arranged in the vertical trunk 11, beneath the slide valve 16, and adapted to direct the flow of pulverized fuelvig front of the nozzle or jet pipe now to be described.
18 is a nozzle or jet pipe passing hcrizontally into the vertical trunk 11 at'a point immediately below the inclined partition 17, and adapted tol force the pulverized coal passing down from saidpartition into the aforesaid manifold 13, along with the gases and carbon flowing toward the same through the conducting trunks 10 and 11. IThe nozzle or] et pipe 1S receives its supply of steam from a supplfv pipe 19 extending to a suit'- able source o steam pressure supply. I I
' 20 is an air supply pipe, which preferably extends transversely through the fire bed of the furnace with a View to att-ain an efficient heating of the air passing through said pipe. Said air suply pipe 20 connects in turn withthe a oresaid vertical trunk 11 at a point 'immediately below the inclined partigrate bars of the same.

aforesaid, and an outlet communicating with a discharge' tube or nozzle 22 which extends through a side Wall, of the furnace and discharges beneath the'grate bars of the fire chamber 4.' 23 is a jetnozzle arranged axially lin said casing 21 and connected by a l'steam-pipe 24 with a suitable source of steam pressurel supply. The above described construction is adapted to take a portion of gases and carbon passing through the trunk y11 and discharge the same under the grate bars, and with a View to regulate the action 4of the described parts, valves l25 and 26 are yarranged in the tubesr22'and 24, for the reg ulation and entire stoppage. of the flow therethrough. t j
In Fig. 4, a modificati-on ofthe manifold l13, and plurality of discharge tubes 14, be-
xfore described, is shown, and com rises a the gases, etc., down against the mass of fuel within the re chamber. j
,l 'Having thus fullyV- describedmy said invention what I claim as new and desire to secure by Letters Patent, is
