. FURNACE.
SPECIFICATION forming partof Letters Patent No. 414,037, dated October 29, 1889.
Application filed April 12, 1889. Serial No. 306,937. (No model.)
To all whom it may concern:
Be it known that we, GEORGE F. GALLAGHER and THOMAS B. MOORE, citizens of the United States, residing at Rochester, in the county of Monroeand State of New York, have invented certain new and useful Improvements in Furnaces; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had t0 the accompanying drawings, and to letters or gures of reference marked thereon, which form a part of this specification.
In our application filed January 16, 1889, Serial No. 296,47 4, the passages for furnishing heated air to the fire-box passed across the center of the grate-bars in both directions, thus virtually making two fire-boxes, and the fire-box was arched over to a point near the front thereof. These features, together with the passage connecting the ash-pit with the rear of the fire-box, constitute a furnace giving satisfactory results; but we have discovered in constructing and operating this furnace in an experimental way that better results are unquestionably obtained by first having the grate-bars surface entirely free of the hot-air passages, one set of the passages starting at the sides and meeting at the center of the rear of the fire-box, and the other set starting also at the sides of the ire-box, extending along such sides, and then returning directly back to the front of the fire-box, and there discharging the heated air. The arch over the fire-box in our present improvement is almost entirely dispensed with, only a short projection from the bridge-wall being left to serve as a deliector for the air coming up from the ash-pit.
We will now proceed to describeand claim the manner in which we have carried out these important improvements.
In the drawings, Figure l is a vertical longitudinal section of our improved furnace, taken on line a: 5c of Fig. 3. Fig. 2 is a transverse vertical section through line @c Fig. l. Fig. 3 is a horizontal section through line y y, Fig. l, with portions broken away; and Fig. 4 is an outside front elevation.
Referring to the drawings, a is tlre ash-pit,
b the grate-bars, c the lire-box, and d the bridge wall, all of usual construction. In front of the bridge-wall is the auxiliary wall c, having the passages f f, leading from the ash-pit to the fire-box between it and the bridge-wall, as in the application hereinbefore referred to.
gis a horizont al extension of the bridge-wall,
which acts as a deflector for the air coming 6o up from the ash-pit. The air-passages are divided into two sets, the rst h h starting from the doors or dampers h h at the sides of the fire-box and passing along the sides to the rear and across to the center,where they merge l into a common dischargeopening h2 at the center of the rear of the lire-box. The difference between these and the passages in the application referred to is that the heated air is discharged in the rear of the fire-box in- 7o stead of the front. The other set of passages la start just above the passages h h at their doors or dampers 7c c, pass back to the rear, and return along the same side to the front of the fire-box, where they discharge their heated air at the openings 7a2 k2. This improved arrangement discharging, as it does, the highly-heated air at the center of the rear of the lire-box and also at the sides of the front of the same, together with an unob- 8o structed grate-surface and the addition of the supply of air from the ash-pit at the rear of the fire-box, produces an intense heat, which entirely consumes all the products of combustion (which go to make smoke) in a manner not heretofore eected by any of our varied constructions. It also eects a larger savingv of fuel, which fact has been clearly demonstrated by actual and careful eXperiment.
We claim--` A furnace having the ash-pit and bridgewall, as shown, a passage or passages between the bridge-Wall and an auxiliary wall, such passage or passages leading from the ash-pit to the fire-box, for the purpose stated, and two sets of air-passages, one set starting from the outer sides of the firebox, extending along the sides to the rear, and joining at the centhe heated air in the rear of the lire-box, the names to this specification in the presence of other set of passages starting from the outer two subscribing Witnesses.
sides of the fire-box, extending along the sides to the rear, and returning along the same ll/IIGHER 5 sides and discharging their heated air in the front of the fire-box, substantially as and for Witnesses:
the purpose stated. JOHN C. I-IEISLER,
' In testimony whereof We have signed our F. J. OBRIEN.
