EDWIN L. BRADY, OF NEW YORK, N. Y.
SMOKE-CONSUMING FURNACE FOR LOCOMOTIVES.
SPECIFICATION forming part of Letters Patent No. 271,027, dated January 23, 1883.
I Application filed February 15,1882. (No model.)
T 0 all whom it may concern:
Be it known that I, EDWIN L. BRADY, ofthe city, county, and State of New York, have in- .vented a Smoke-Consuming Furnace for Locomotives, of which the following is a specification.
The object of my invention is to provide a simple apparatus applicable to locomotive-em gines, whereby the objectionable use of the exhaust-steam jets for producing. an artificial draft may be avoided, the waste products of combustion hitherto dispersedand lost may be returned to the fire andconsumed,tbecinders carried through the smoke-fines may be deposited on the road-bed instead of being scattered about, and whereby other and additional advantages may be attained,the natureof which will be readily understood from the annexed description, and which will be herein subsequently specified.
To these ends my invention consists of a novel combination of a collecting, air-funnel placed upon the front ofthelocomotive, aclosed pipe leading from the contracted end of the funnel to the fire,a smoke or draftfunnehflue, or tube opening into the air-funnel in the enlarged portion thereof, and a damper placed in the smoke-flue and arranged to open and close at pleasure an orifice allowing free escape of the smoke in the ordinary way through the mouth of the ordinary smoke stack or funnel or its equivalent.
Referring to the accompanying drawings,
Figure 1 is a side view of a locomotive titted with my invention, and Fig. 2 is a front View of the same.
A represents an air-collecting funnel, made of sheet-iron or other suitable material, having a flaring mouth, and supported upon the pilot the fire-grate is tightly inclosed,so as to allow access of air to the fire only through the tube.
The ash-pan and other appliances for removing and depositing ashes may be of any desired construction.
0 represents the smoke stack or chimney of the locomotive, which is in free communication with the smoke-box and with the tubes through which the flame, smoke, and unconsumed products of combustion are conveyed,as ordinarily.
Connected to the smoke-stack at or near its top is a pipe, 1*, the lower end of which opens into the air-collector A at a point considerably in frontof the contracted orinner portion thereof, so that the heated air,smoke,and other unconsumed products of combustion escaping from the. end of the same may be carried back to the fire by the current of air collected by A and forced into the pipe B as the locomotive moves. The end of the pipe F is cut off at an angle, as shown, so that the air-currentrushing past the mouth of thepipe maynot be carried upward into the pipe,so as to createa back draft, but by passing quickly by the opening may tend to exhaust the air and'gases from said pipe. v
G represents a wire screen rising nearly as high as the mouth of the pipe F, and serving to catch the cinders dropping from F,which would otherwise be carried into the pipeB and finally clog the same. The cinders, after being caught by the screen, fall back upon the bottom of A, and are finally deposited upon the road-bed.
, D represents a damper placed in the smokestack 0 at a point above the pipe F, and operated bya cord,E,leadingto the engineers cab. When said damper is closed, which is its condition while the locomotive is running, the smoke, &c., passing from the fire can pass only through the pipe F. When the damper is open,
which is its position when the locomotive is stationary, a free draft-passage through the top of the smoke-stack is formed, and the fire then burns with a natural draft.
The operation will be readily understood. When the locomotive is running the damper D is closed and the air collected by the funnel A is forced into the tnbeB, carrying with it the heated air and the waste products of combustion discharged from F or drawn therefrom by the rapid passage of the current of air forced past its opening by the rapid motion of the 10- comotive. The arrows show the direction of the currents.
motive is at rest, the damper D is opened, thus pose being objectionable because of its corroding action, while, moreover, the heat of the steam is dissipated and lost. By my plan, the steam being no longer required to create an artificial draft, it can be employed in Warming the water in the feed-water tank, which. is the proper and economical disposition of it. I am also enabled to return to the fire the large percentage of unconsumed products ofcombustion in the shape of gases and smoke, re-en'forced with the fresh oxygen necessary to their ignition and complete combustion. Moreover, under my plan there will be entire freedom from smoke,cinders,and smells on passenger-trains whoseengines are fitted with this appliance, while at the same timethere is no danger of setting fire to anything along the line of road,
as all einders, after striking the wire screen, are deposited by their own gravity on the roadbed.
It will be observed that when at rest at a station the engine obtains draft justas the engines now in use do. I
What I claim as my invention is 1. The combination, with the smoke-stack G, of the flaring air-collector A, the pipe F, connected directly to the smoke-stack near its top, and extending downward in front of the same through the Walls ofthe air-collector to a point near its center, said pipe being cut off at an angle to the line of motion of the air-current, and the damper D, placed in the smoke-stack near its top above the point at which the pipe F is connected.
2. The combination of the pipe F, the aircollector, and the screen Gr, placed in the aircollector in front of the pipe connected thereto at its contracted end, and behind the pipe F, as and for the purpose described.
