IMPiz'ovEMIENT IN 'Hor-AIR FuRNAcEs.
` The Schedule referred to in these Letters Patent and making paxt of the lame.
I, SAMUEL B. SEXTON, of Baltimore, in the State of Maryland, have invented a new and improved Warm-Air Furnace, of which the following is a specification. l
Nature and Objects of thevfnvention.
The improvements relate to the construction of dellectingplatesin the upper` chamber 'of the-furnace; a shiftable arrangement, by which the discliargepipes can be placed on either side of the furnace; anda damper arrangement in the said pipes, by which the caloric current is allowed to pass. immediately to the chimney, or is directed` downwardrto pursue a more circuitous course. l f f Description of the Acconwmtytng Drawing.`

General Description.
In gs.`1,2, and 3, the furnace is represented as inclosed in a brickwork or other casing, A.
The fire-chamber has a aring fire-pot, B, rvwith au interior re-clay lining, b, and a dome or arch, c, whose edge rests upon the nre-pot.
This dome has such adegree of lateral extension that it affords space for a number of openings around the central trunlk or magazine-chamher D, which re ceives its fuel through the chuteE.
F is a door, with a register, to admit air when required, in order to damp the energy of the re.
, G is the ash-pit, and
H, 'the grate, which has two motions, one, a rccip rocating back-and-forih, in order to stir the lower bed of coals, and cause the ashes to drop between the grate-bars into the box below; the other motion being a rotation upon the axis g, in order to dump the contents of the tire-pot into the ash-pit.
On' the upper edge of the grate-bars are prongs, which project upwardly, and stir .the coals when the grate is reciprocated, in order to assist in sifting out the ashes.
Thev top of'l the ash-box is extended'laterally, so
as torest upon steps furnished by the brick casing,
and thus` form a support for4 thereverting dues I l', which will be` describedpresently.
l Holes are provided inthebase-p1ate`h, to allow the upward passage of air from the space around the ash-pit.
' G is the door of .the ash-pit, and is the air-supply, for the re enters at that aperture. ,i
J is a door in the outer casing;the'aperture admits air into the chamber K to be warmed andv carried off. by the duct It', for the purpose of heating the apartments of the building. v
The door J is placed opposite to one ofthe openings, c, in the arch of thefireFplace, in order that kindling may be introduced atthis point,or the poker to stir the fire.
vA mica door closes the openingc, except when it is necessary to reach the chamber' for the purposes stated, or for cleaning the lues or chambers.
Another opening, c, is afforded at the rear part of the furnace, to be used when the mode of setting the furnace may render it available.
From the top ofthe arch O rise fourl hollow columns,M, of peculiar' form, and'these serve as lues to conduct the caloric-.current into the upper chamber L.'
Each ot' the columns is cast in two parts, which may be compared 'to hollow frustums, united at their larger ends, the `smaller ends communicating with the fire-chamber and the upper chamber L respectively.
This shape allows them to he' cast without a core, as the conical form permits the pattern to be lifted onn` the sand. The `shape also affords a mid-length enlargement for thegas andsmok`e, and increases the radiating surface. They are also more easily and closely fitted together and atles's cost. The chamber L has four converging ducts, which lead the gaseous contents ofthe columns M toward the central due N. Each current just before reaching 'the central chamber L dives down beneath a plate, O, which prevents it from escaping immediately up the chimney. g
P is a` damper at the bottom of chamber L.I When the re is irst lighted this damper maybe opened to allow escape of the gas and smoke immediately` up the chimney before th'e heat has' established an ascensive current of suiificient force to traverse thc-more 'circuitous passages. l
R is'an elbow and horizontal line, which maybe made to reach out from the central ueN in anydirection, according to' conueuience, or to suit the shape or position of the cell K in which the furnace is placed.
v T'heue R leads to a shorthorizont'al fine, S, which connectstwo pipes I I'. v
A dampen-s, is placed between the intersection of pipes lR. S' and the discharge of the latter into the pipe I. When this damper is closed. .the gas and smoke are compelled to pass down pipe I', along the flue V, and then up pipe I, to the elbow T and chimney W.
. X is a .water-re.servoir on the ue U, toabi'd aqueous vapor to the .air passing -through the chamber K.
Claims.
1. The reversible damper-pipe S, arranged. in connection with the elbow-pipe R and.` radiating fines IV I', in the manner shown and described, to admitlof changing the damper from sie to side to suit the construcas and for the purpose described.
