ROYAL F. BROWN,OF CHICAGO, ILLINOIS.
IMPROVEMENT IN HOT-AIR FURNACES.
Speciiication forming part of Letters Patent No. 184,829, dated November 28, 1876; application filed July 1, 1876.
` Chicago, in the county of Cook and State of Illinois, have invented an Improvement in Hot- Air Furnaces, of which the following is a specification The nature of my invention relates to an improvement in surface-burning air-heating furnaces of that class wherein the gaseous products of combustion are conducted by divinglues into base-dues, thence by ascending ues into the direct iiue, into which the gas/may be allowed to pass directly, it' desired; and it consists in the peculiar constructipandcombination of the several parts, asvm'ore fully hereinafter set forth.l
vFigure l is a perspective view of the furnace with the casing removed. Fig. 2 is a partial front perspective view, showing the manner of supporting the grate-lever. Fig. 3 is a vertical section at x w in Fig. 4, which is a horizontal section at y y.
In the drawing, A represent-s the ash-pit, having a circular opening in the top, in which is hung a rotary grate, B, on a trunnion-bar, a. The grate is cast with a stationary lever, b, projecting to the front, which lever is supported by a segmen t-shaped bar, c, hinged at one end to the side wall of the ash-pit, while the other end is received in, and supported by, a socket-bracket, d, cast on the other side wall. When it is desired to tilt or dump the grate the bar c is swung out to one side, when the bar b may be lowered. C is the fire-pot,
snrmounted by a hollow combustion-ring', D,
triangular in crosssection, and perforated just under the inner angle, as shown. The air to promote the combustion of the gases enters the ring through a throat, c, which may be tted with the usual register. E is the combustion-chamber, mounted on the ring D, and is fitted with the usual feed-door in front and exit-nue F at the back, inwhich there is hung a damper, f. lwo shortjlateralfiues at the top of the com bustion-chaniber convey the gases into diving-dues Gr Gr, one at each side, whiohdeliver the gases intoth front end ot' a segment-shaped base-flue, H, at the rear end of which rises an ascending iiue, I, which conveys the gases into a cross-lue,.J, at the back of the furnace, and from which rises the main exit-due F', which is intersected by the direct-draft flue F. When the damper in the latter is closed the heated gases pass down the diving-dues into the base-fines. Passing through these they rise through the ascending lines into the cross-flue before finding an eXit at a greatly-reduced temperature, owing to the large area of radiating-surface which they have traversed.
What I claim as my invention is In an air-heating furnace, substantially as described, the combination of the diving and ascending lues and base and cross lues with the ash-pit, grate, iire-pot, combustion-rin g, and combustioncharnber, substantiallyv as set forth. v
