BASE-BURNING- STOVE. h

and county of Albany, in the Stat-e of NewYork, have linvented certain new and useful Improvements on y Magazine Parlor-Heaters; and I do hereby declare thatthe following is a full, clear, and exact description* thereof, reference being had to theaccom panying drawings, making part ot' this specification, in which- Figure 1, sheet 1, is a diametrical section through 'a magazine parlor-stove having my invention applied to it.

y Figure-2, sheet 2isa side elevati-on of the perforated lower section ot' the stove, with -a portion broken away to expose the re-pot. l

Figure', sheet 2, `is a section taken through fig. 2, in the horizontal plane indicated by line a: x. l, Similar letters of 'reference indicate corresponding -parts in the seyeral iigures.

'lhis invention relates'to certain'ncvel improvements (Jn-fuel'magazine parloihheatergwhich .are so constructed ,that the products of combustion, after rising from the re-pot,'ascend through an illuminating section, through a vertical flue-space surrounding the thence passoi' into the main une-or chimney.. l .g The object of' my invention is mainly to provide such a stove with a lire-pot, which is composed of soapstone, or other suitable ,mineral bricks, applied in an open or skeletonl frame in such manner that the bricks `-willI be exposed to viewthrongh this frame, and to arf. -range` this ,fire-pot within a perforated'case, which forms a portion ofthe outer wall of the stove, `whereby y heat will be radiated directlyfrom the mineral lining of the pot` into the room, as will be hereinafter ex.

plained. p

f Anotherobject of my invention is "to construct a brick-lined fire-pot, which is enclosed by aperforated .casing of a prismatic or` `many-,sided form' `internally and externally, for the purpose of preventing lodgement of ashes around the sides of the body'of coals, and alsoV for allowing currents of air to ascend into thebody of coals at the angles `formed by the junction of the v er-4 i `tical edges oi' the brick lining, `asvwill be hereinafter explained.

To enable others skilled ,in the art to understand `my invention, I will describe its construction and operation. y

*In the accompanying drawings, Arepresents the base section of the heater, and B is .a perforated section,`which isgmonnted upon section A, and forms part of the outer wall of the heater. v

i Within the perforated wall B, and supported upon the base` section, is an elevated grate-section, O, in

which a circular movable dumping-grate, b, is sup- .I ported upon a bearer, b. Uponthis grate-sectlion the The Schedule .referred to in these Lettera Patent-and making partof the same.

re-pot D is supported'and held `in place in' any suitable manner.

i Between this [irc-pot, D, and the 'perforated section, B, is'an airicirculating space, g, extending entirely around the tire-pot, and.coimnunieating `with the external air through the perforations made through the section B. The annular space g is closed at top by the flange f, of a ring, E, which flange also serves to hold theiire-pot in place at its upper end, asshown in iig. 1.

Upon the ring E, the illuminating-section F is supported, with-its hinged mica frames or doors h, and `upon vthis section F,-the drum G is supported and held -in place, carrying on its upper end the cap H, with its cover I.

The magazinveK, with its removable foot l", maybe suspended from the cap H injtheusual well-known manner, and provided with a feed-opening through its upper end, closedby a valve, l.

By meansof the flue-passage j, constructed in the space formed between the magazine and the-drum G, ythe products of combustion are caused tov risc a's high as `the cap H, before passing oi through the exitfpipe.

ation from, and by Contact with the sides of the firepot, which chamber isseparated from the combustionchamber, enclosed by the illuminated section by the annular diaphragm ortlange f.

Ihe lire-pot D, which `I prefer to make of a polyg- `onal shape,`is composedpartly of soapstone or other suitable mineral bricksections d d, and partly of' metal. 'The metal part consists of narrowveltical bars e', of angular form in cross-section, .united at their extremities to narrow'annular bauds, e e, as shown in. fig. 2. i

These bands and strips constitute an open or skeleton frame, which is *adapted for receiving within it 4and keeping in place thc tire-brick sections d, the abutting edges of which arey suitably bevelled, as shownin fig. 3. yThe object of employing a skeleton frame is, that I may be enabled to iirmlyzhold the brick lining, and

exposed, as shown in figs. 2-aud 3.

It is well known that heatwhich is radiated from i highly heated metallic tire-pots, is very dry and unpleasant, which is not the case with substances of which tire-bricks are made. I therefore expose nearly the` whole of the outer surface of the fire-brick lining,

and arrange this fire-pot within a casing or outer wall,

vat the `same time have the outer surfaces of this lining B, which is perforated in.y such manner as to allow a direct radiation of heat into the room from the fire-pot through the spaces or perforations in said wall B.

For the purpose of protecting the upper ends of the iire-b1icks, and at the same time affording a slightly flaring mouth to the re-pot D, an upwardly-flaring ring, D', is arranged upon the fire-pot, as shown in iig. 1, which ring can be tilted when' itis desired to reriiove any one or more of the brick sections d.

, To facilitate the removal of the brick sections d, to repair the fire-pot, I employ doors h for the openings of the illuniinating-seetion, which are hinged at their lower ends at i,so that if desirable, all the doors can he swung open atV one time, to allow free aecessnto the combustion-chamber and tire-pot. I do not eoniine myself, as far so the skeleton frame or tire-brick lining are concerned, to a prismatic or many-sided fire-pot, as the metallic portion of such a'pot might be made circular. y

The advantages which result from the use ot' a firepot presentingbbtuse angles at-the junction ot" its bricks are, that the coals will not lie so close to the sides of this pot as they would if it were circular upon its inner side,a'nd vertical air-ducts will be left which will allow the ascent of air through the rire-pot to support combustion, and also allow ashes to 'fall freely intoV the ashpit from the sides of the bedof. coals, when the grate is shaken. In practice, the perforaltions through case B may extend entirely around it,

.and they may he made so as to give this case a very beautiful and ornamental appearance.

VI have herein described a rehrick-lined lire-pot of plisfnatie form, with the metal casing which cncloses .the lining made so as to expose the fire-bricks through it, but I do not desire to he understood as confining lined fire-pot, as such form, if adopted for an ironpot without lining or openings through its sides, willhe found very advantageous.

I do not claim as my invention such arlangements as are shown in the Letters Patent of Porter Dodge,

myself', so far as the prismatic form is concerned, to a l February 21, 1865, D. G. Littlefield, June 25, 1861,
