WILLIAM YVHEELER HUBBELL, OF PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN FURNAQE-DOORS OF LOCOMOTIVES.
Specification forming part of Letters Patent No. B9L1l', dated May 332, 1877; application filed February 15, 1877.
To all whom it may concern Be it known that I, WILLIAM WHEELER HUBBELL, 0:" Philadelphia, State of Pennsylvania, have invented an Improvement upon Furnace-Doors of Locomotive and other Similar Steam-Boilers, of which the following is a specification The object of my invention is to force air through the perforations of thechamber of the furnace-door patented by me, of date February 13, 1877, to supply with force jets of air to consume the smoke and combustible gases which arise from the fuel in the furnace, on which invention this is an improvement; and the' nature of this improvement consists in constructing the furnace-door with an air-supply pipe arranged under a fixed pipe extending upward, and constructed to receive a supply of air forced down it by the lmovement'. of the engine, or by a'steam-jet. The construction of the door is described in the specification of my said patent, also in this in general terms.
Referring to the drawings, Figure 1 is a the iron perforated jacket, or conical or taf pering plate b, projecting into the furnace, and forming an inner perforated chamber, d, with a. front end, b', and perforated sides c. .The door has an opening, z', through it, and adjustable slide-cover k, with set-screw Z oppo site the upper or unperforated part of the chamber, all of which are also described in my said patent. Y
The perforated chamber d may be a pointed cone in place of the plate b. The front end of the chamber d may have an inverted conesheet, pointing to the opening i, instead of the plate b. The top of the chamber may be at, sloping down forward, as modications I have-contemplated, and may be perforated or nperforated.
To the inner face of the opening i I secure a bevel-collar, o, and in front of this openingz' I attach to the door an elbow-pipe, p, constructed to form an annular space between its discharge-mouth at t', the collar o, the elbowsection q extending upward, and enlarged at 1 near the top of the door, so as to form an annular space between its mouth and the Vlower end of the pipe ss. When the door is closed the section q is under pipe s s, which extends up above-the b'oiler, and has an enlarged bellmouth, t, extending horizontally forward to the outer air, to catch the air and drive it down the pipe s s, through the elbow pq and opening t', into the door-chamber d, from which itpasses with force through the perforations, among the gases and smoke, to consume' together in the furnace. Ihe upper end of the pipe s s at w is open to admit air in case the wind blows in the direction of movement of the locomotive, or of pointing of the bell-mouth t.' This upper end w has a plate roof 01 cover, a', supported above it to keep out the rain, yet admit the air to enterit. A valve, r, in it shuts it when not needed. A valve, c', in the pipe regulates the supply of air. When the engine moves forward the pressure ofair on the bellmouth t generally drives suiicient down to supply the chamber of the door. As au auxiliary force when needed, I extend a small steam-pipe, y, from the boiler into the pipe s s below the valve c, or .nearer the top of the pipe s s, and admit a tine jet of steam downward to force the air down into the chamber; but the jet must be very tineabout a tenth of an inch-and the condensed steam runs out ofthe space at z', or a hole in the bottom of the joint p.
The water-space around the door is marked n a; the crown-space, a; the furnace-fuel, m; the furnace side, m; and the grate-bars, z. In the lower part of the door I make a cleaninghole, e, with a slide-cover. The elbow-pipe p g may be solid to the door-plate, withoutthe annular space at i; but the annular space at z serves to increase the supply of air, and also the annular space atrserves to increase and to admit air in standing or firing up in the furnace.l
What I claim is- 1. The stationary supply-pipe s s, in combination with the elbow-pipe p, having an eX- panded mouth,r, and attached to the door, conical perforated chamber d, bell-mouth t, valve 1", and valve fu, to force and regulate the supply of air,lsubstantially as described.
2. In combination with a furnacedoor provided With a conical perforated chamber, d, and bevel-collar o, the elbow-pipe p, securedto the door, and stationary pipe s s, the collar o, forming with the end of elbow-pipe p an annular space, as and for the purposes described.
3. In combination with a furnace-door, provided With an elbow-pipe, p, having a daring end, q, the pipe s s, having mouth 'w and bellmouth t, as and for the purposes set forth.
4:. In combination with a furnacedoor provided With chamber d and elbow-pipep, theV pipe s s, having bell-mouth t. mouth w, and valves o r', as and for the purpose set forth.
5. The pipe s s, cover 'mouth w, and iut nace-door', provided with elbow-pipe @and chamber d, `all combined as and for the purpose set forth.
r6. In combination with a furnace-door prol WM. W. HUBBELL.
