METHOD OF CONSUMING SMOKE.

SPECIFICATION forming part of Letters Patent No. 899,062, dated March 5, 1889.

Application tiled May 2 5, 1888. Serial No. 275,023. (No modela f To (LIZ whom z' 11mg/conce/'11:

Be it known iliatl, Rionero HEM-ir MICH- Britain, residing,r at Redruth, in the county of chimney must have a damper on it, or be disconnected with the lire-place, and then be con- Cornwall, England, have invented a new and uselnl Method ot' Consuming' Smoke, ol' which the following,l is a specification.

lhe object ol this invention is to meclmnt retort, or other furnace, to be there consumed,

ically separate the combustible from the innected with a rareiied smoke-drain placed in The sin oke and other gases are to be drawn ontV ol' the flue of the eliinniey and out of the smoke-drain bya fan or other means et producing an exhaustion,

combustible gases generated in a furnace or other fireplace, and depends mainly upon the the said smoke-drain at Various intervals to physical properties ot the uneonsumed gases themselves.

For the purposes of my invention l return the unconsumed gases back again into the same or another fire, so as to produce their complete combustion. I take them as soon as back again by a pipe or other suitable channel, (which maybe termed the return-tlue,") and reintroduce them into the lire-place at or near the door, or into such other part of the lire-place as may be found most desirable, and `in such a manner as may bc most likely to insure their complete combustion. The process of returning' them into the lire 'is to go on continuously until they are consumed. The means by which this object is to be attained is a fan or other motor, placed in connection with the return-line, which is to take the unconsuined combustible gases and cause them to re-cnter the fireplace and compel` them to travel in such a manner .as may be required for their complete combustion. The action of the said fan or other motor is to be continuous, always bringing the unconsumed combustible gases back again into the tireplace, and there completing their combustion by mixing them with the oxygen of the air Supplied under the fire-place in the ordinary Way in the necessary quantities to effect this result. The draft-of the fire is also to be regulated by the said fan or other motor, thereby producing a brisk sharp fire or one just sutiicient to consume the gases arising` from it, at the option of the fireman. l

For promotingl the sanitary condition of towns this invention may be applied to the fire-places ot dwelling-houses or streets of houses. In this case the ascending; flue or and blown into the lire-place of a boiler, gasas before described.

The sewers should also be connected with take away the foul gases from them, so that they may be dealt with, as before described, in the furnace provided tor the purpose, as aforesaid.

And in order that my invention may be they have left the tire-place and conduct them more fully understood and carried into practice, l now proceed to describe the same with reference to the accompanying drawings, in which similar letters indicate corresponding parts.

Figure l isa side elevation of my invention as applied to a marine steam-boiler. Fig. 2 is a plan of the same.

The smoke arising from thore-place is led to a fan or other exhauster, A, by means of a pipe, ci, connecting in practice with the iireplace and the falrcase, and from thence led back again to any convenient part ot' the fireplace by the return'ilue B.

It is well known that the specific gravity of the incombustible gases is greater than that of the combustible gases, and I taire advantage of this fact in my invention in the following manner:A lVhen the mixed gases are led into the fan or other exhauster, A, the centrifugal force developedthereby will cause the heavier gases to arrange themselves around the periphery of the said fan or other reo It is Well known that ii the separator is in l the second. position, C2, the constant discharge l of the mixed gases into the tire-place will eventually extinguish the lire. Now, the separator C can be so regulated that it shall take i up any position between these two extremes, l and since, by reason of their greater Weight, the ineombustible gases are arranged,as before stated, around the periphery of the fan or other exhauster, it is obvious that the said .f separator C can be made to out off any required quantity of the said ineombustible l of the feeding of the combustible gases being gases, and so divide the gases thrown off from the exhauster as to lead the heavier incom- 5 bustible gases from the periphery of the ehiml ney E, and return the lighter combustible gases along the return-Hue B. It will readilybe understood that il' a smokedrain were constructed in any convenient lol oality and provided with an exhauster tted with a separator pivoted so as to revolve in the same plane as the exhauster, the smoke l from dwelling-houses and othenplaees would be led therein by the vacuum caused by the revolution of the fan, and could there be separated and the combustible gases utilized in any Convenient manner.

What I claim is The method herein described for consuming smoke for its utilization as fuel, which consists in mechanically separating the combustible from the incombustible gases, and Varying the feeding of the lighter combustible gases tothe fire, such separation being efi feeted by the centrifugal force developed by a rotary fan or exhauster, and such variation effected by the adjustment or manipulation of the damper, substantially as set forth.

In testimony whereof I have hereunto set my hand this 24th day of April, 1888.

RICHARD HENRY MICHELL.
