IMPROVEMENT IEN SMOKE AND GAS CONSUMERS FOR ENGINES.
Specification` forming part of Letters Patent No. 157,619, dated December 8, 1874; application filed Ottober 10,1874.
To au L Uhom it may concern: Y
Be it known that I, DAVID MATTHEW, of Portland, county of Multnomah and State of Oregon, have invented a new and useful Improvement in Smoke and Gas Consumers for Engines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings making part of this specification, in Which- Figure l is a vertical longitudinal section of my improved smoke and gas consumer. Fig. 2 is a longitudinal section of the same in a horizontal plane, w x. Fig. 3 is a vertical transverse section of the same.
The object of my invention is to arrest the sparks and cinders, 4so that they shall not escape into the open air; also, to secure a strong draft through the smoke-stack, and, while these two ends are attained, effect a separation of the heavier and partially-consumed gases from the lighter gases alid sparks or cinders, and return the heavier gases and sparks, in a highly-heated conditiony and under a blast-pressure, to the combustion-chamber, either above or below t-he grate, or to both at the same time.
The nature of my invention consists 4in certain new and improved constructions and combinations of parts, as hereinafter described and specifically claimed, whereby the above-mentioned objects are secured.
To enable others skilled in the art to make and use my invention, I will describe it.
A in the accompanying drawings is a locomotive-boiler, having a fire-box or combustion-chamber, A1, fines A2, a smoke-box, A3, and a smoke-stack, A4, substantially the same as in ordinary boilers. E El E2 is a blast-pipe, made of sections, and arranged within the smoke-box at the base of the smoke-stack, and centrally in line with the stack. The sections of this pipe have each two vertical sides, E2, and two inclined or curved sides, E El, which latter converge and diverge as they rise between their upper and lower ends. The upper section E1 of the'blast-pipe is wider than the lower section, and outside of the lower section, which extends up some distance into the upper section, entrance-passages for air, gas, or sparks are provided in the lower end of the upper section, as shown. Within the blast-pipe E E1 a downwardly-tapering separating-screen, F, is constructed by arranging on incline planes narrow parallel slats a short distance apart on opposite sides of the center ot' the pipe. The lower end of this screen is formed of a V-shaped slat, which acts as a parting-strip for the blast, sparks, and gases to strike as they rise and pass into the blastpipe. Gris a combined hood and conductor placed below the blast-pipe. H H are eX- haust-steam or blast nozzles, entering the smoke-box in the usual manner, and discharging the steam into the pipe G, which conducts it into the blast-pipe. l I are lateral segmental chambers around the base of the smokestack, a-nd in communication with the blastpipe E El, as shown. K K are broad passages leading down from the segmental chambers around the outside of the boiler, and K1 K1 `are pipes connected to these chambers, and
running from the same on the outside of the boiler to the combustion-chamber of the lireboX, and entering the latter above the bridge or shelf L by transverse tubes K2, passed through the outside and inside walls of the nre-box, as shown. The tire-box has its bridgepiece or shelf L between the top sheet and the grate A6.
The apparatus thus far described would discharge the heavier gases and sparks directly amid the flame which rises from the fuel and rolls toward and up over the front edge of the bridge, and from there passes into the dues of the boiler. This construction would insure the burning of the returned gases and their utilization as fuel; but in order to more perfectly use these returned gases as a fuel I have constructed a hollow transverse chamber, M, upon the rear top portion of the bridge L, and continue this chamber down through the back part of the bridge or shelf to the plane of the grate, and in front of the ordinary back wall of the lire-box, and have constructed the iire-box with a curved perforated supplemental back wall, N, as repre-sented; and at the bottom of the vertical portion M of the chamber M a hinged valve or gate, O, is placed, to open downward and admit access of iiowin g gases and sparks into the ash-pit A5. The chamber M M thus formed is closed on all sides, ex-
cept where the perforations in plate N and the passage covered by the valve and the passages for the tubes K2, Which enter it, are formed.
In practice the parts Which are exposed to the very intense heat are made of the best known material for resisting heat-for instance, heavy cast-iron, plumbago, tire-clay, or asbestus.
The general construction and operation of the contrivance are as follows: The steam-cylinders being on the sides of the smoke-box, with the exhaust-pipes leading in at the bottom to the center, the exhaust steam is discharged from the nozzles G of these pipesinto the blastpipe E El E2 and against the parting-strip ot' the tapering screen or separator Esimultaneously with the ascent of the blast, the sparks and gases are caused to tloW with great force into the blast-pipe, and these, striking the screen, are separated by the slats of the screen, the lighter gases escaping between the slats along with the blast and the draft, and the heavier gases and sparks being detlected and carried by the force of the blast and suction into the segmental chambers I, and from thence conducted by the pipes into the chamber M M', where they are intensely reheated or superheated, and then discharged through the pert'orations in the plate N into the fire above the grate, and throughthe valved passage ot' the ash-pit up through the grate. The reheating ot' the gases prevents chilling the iire by their discharge therein, and the constructing of the blast-pipe with openings at different altitudes places the heavier gases and sparks more perfectly under the influence ot' the blast.
Itis believed that the invention herein described Will render railroad travel much more comfortable, prevent accidents from lyin g sparks, and save fuel to a very great extent.
What I claim as new isl. The downwardly-tapering lattice -Work screen or deiiector, in combination with the sectional blast-pipe having blast-openings at different altitudes, the blast-nozzles, smoke-box,
and stack, substantially as and for the purpose described.
2. The downwardly-tapering lattice-Work screen or deector, in combination with the side chambers for receiving the separated heavy gases and sparks, the sectional blast-pipe having blast-openings at different altitudes, the blast-nozzles, smoke-box, and stack, substantially as and for the purpose described.
3. The combination of the side receivingchamber I, the gas-conducting pipes K1, the fire-box or combustion-chamber A1, the blast and separating devices, the tlues, smoke-box, and smoke-stack, substantially as described.
4. The combination of the side pipe K, which is connected With the interior ofthe smoke-box by means of a passage located on one side ot the passage of the smoke-stack, the exhaust blast-nozzles, and that part lof the chamber of the re-box which is above the shelf or arch, whereby the pressure of the exhaust steam is caused to positively force the separated gases back into the tire, substantially in the manner and for the purpose described.
5. The superheating or reheating chamber M M', constructed above the bridge or shell' in the rear portion ot' the combustion-chamber, in combination With the gas-returning pipe or pipes K K1 and the combustion-chamber, substantially in the manner and for the purpose herein described.
6. The combination of the combustion-chamber, having its back Wall perforated above the grate, with the back portion M of the reheating or superheating chamber M, the valve or gate for compelling the gases to enter the tirebox above the grate, and also permitting them to go into the ash-pit, and the gas and spark returning pipe or pipes, substantially as and for the purpose described.
DAVID MATTHEW.
