SMOKE-CONSUMING FURNACE.
SPECIFICATION forming part of Letters Patent No. 397,135, dated February 5, 1889.
Application filed November 17, 1888. Serial No. 291,114. (No model.)
T 0 all whom it 77'LILZ/ concern:
Be it known that l', (oRNnLIUs McGINNIss, a citizen of the United States, residing at Ohicago, (ook county, Illinois, have invented certain new and useful Ii'nprovements in Smoke-tonsuming Furnaces for Locomotives, of which the following is a specification.
In the drawings, Figure 1 represents a vertical section of the fire-box and a portion of the smoke-tines and boiler of a locomotive containing my improvement; Fig. 2, a perspective view of the device for opening and closing the fuel-door and holding the same in any desired position.
A isthe fire-chamber of the locomotive; B, the grate-bars; the fuel-door; D, a hood or apron surrounding the fuel-door; E, an arch of tire-brick; F F, the smoke-dues; G, rotating hand-levers; q, a spring-catch looking into the holes in a plate, ll, attached to the outer corner of the apron D.
In constructing my device, I make of iron or other suitable material a hood or apron, I), of the form shown in Fig. '1. This is preferably bolted or otherwise securely fastened to the outside of the boiler in such manner as to inclose the fuel-door at the top and sides, leaving an opening at the bottom, but may, if desired, extend some distance into the firechamber. Through the outer and upper edge of this opening or hoodI pass a rod,
I, having hearings in the sides of the hood, so as to allow it to revolve therein, and to this rod I bolt or otherwise securely attach a me tallic plate, which serves as a fuel-door,which is broad enougl'l to close the opening into the furnace and long enough to extend somewhat into the fuel-clnnnber. To open and close this door and hold it in any desired position, I attach to one of the outer ends of the rod I a lever, G. in Fig. 2, another lever, g, carrying a pin at its lower end, which passes through the lever G and enters one of the holes in the quadrant-plate II, which is fastened to the end of the hood or apron, so that when the lever G is drawn back in opening the door, this pin, entering one of the holes in the plate, will hold both door and lover. The construction and operation of this device are plainly obvious from an inspection of Fig. 2 of the draw- This has attached to it, as shown ings, and need no furtherdescription. I next construct of tire-brick or other suitable material the arch E, of the shape shown in Fig. 1. This arch extends downward along the forward wall of the lire-chamber to a point near the top of the grate, and is supported in place by studs fastened into the wall of the fire-chamber. These studs being covered by the fire-brick are thereby prote oted from the heat. This arch is made with a curve at its upper end and preferably extends some distance beyond the rearward ends of the smokefines.
The grate-bars, smoke-lines, and other details of construction do not dilfer from those in use on ordinary locomotives and therefore require no detailed description.
My device operates as follows: \Vhen the door (3 is opened, the air, which is drawn into the fire-chamber, striking against the door is deflected by it downward across the surface of the fuel, strikes against the arch, passes up the same, and is forced backward by the curve at the upper portion thereof, then passes around the top of the arch and out through the smoke-fines at the stack. The effect of this is to feed air to the fire in sufficient quantities to thoroughly consume the smoke, as the air not only passes over the fuel in first entering the fire-chamber, but, owing to the curved form of the upper portion of the arch, is deflected back with a somewhat r0- tary motion, so as to pass again over the fuel, insuring the thorough consumption of the smoke and consequently a great saving of fuel. 4
The distance which the door should be opened must necessarily depend somewhat upon the OlPCLUDStflIlCGS of each case; but when the locomotive is running I consider a space of about half an inch enough for the efficient working of the device.
\Vhat I regard as new, and desire to secure by Letters Patent, is-
l. The combination, with the fire-chamber of a locomotive, of an arch curved at its upper end, an inclined door for, directing air against such arch, and an apron secured to the outside of the lire-chamber in which the door is hinged, substantially as described.
2. The combination, with the firechamber IOO of. a locomotive, of an. arch curved at its nplovers G G, phife TI, and arch E, all arranged per 0nd and extending back of tho l'GHIWFLId and (morn-ting substantially as described.
vnd of the smoke-fines, an inclined door for v ,1 i T Y i directing air against such arch, and an apron ()hh b 5 SQCUITQd to tho fire-chamber in which Tho door \Viinvssos:
is hinged, s11])smntiaily as described. WM. .1. HOUJIY,
