Specification forming part of LettersbPatent No. 116,365, dated June 27, i871.

To all 'whom it may concern:

Beit known that I, GEORGE B. SNnDER, of the city, county, and State of New York, have invented certain new and useful Improvements in Base-l3urning Fire-Place Heaters and Stoves, of which the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing forming part of this specication, in which- Figure l represents a side elevation of a fireplace heater constructed in accordance with my invention; Fig. 2, a sectional elevation taken as indicated by the line me in Fig. 4; Fig. 3, a plan 0f the heater; Fi g. 4, a horizontal section through the line y y in Fig. l; and Fig. 5, a like section through the line z z.

Similar letters of reference indicate corresponding parts throughout the several iigures.

My invention consists in a certain arrangement of air-heating or radiating pipes, through which the products of combustion are passed, the saine consisting of upper-side pipes, which connect with the body of the heater near its top side dippipes, and up-takepipes that connect by branches above with the main escape-pipe or iiue. By this arrangement of the' pipes that carry oli' the products of combustion, all the available heat derivable from the latter is utilized in heating the air outside of the pipes without interfering with or impair-ing the draught. The invention also consists in a novel arrangement of an air-heating chamber or chambers in the case of the heater, into which the air to be heated is introduced through holes in the bottom, and distributed when warmed through holes inrthe top, said air-heating chamber or chambers being exposed on its or their sides to radiation from the ash-pit and to the base-liuc of the heater. The invention likewise consists in a novel and convenient means of hanging and securing the front plat-e of a lireplace heater, by inserting said plate in rear of side lugs on the base-plate, and securing it by a screw to the top of the heater, whereby increased facility is afforded for introducing said front plate in rear of the center ornament of the mantle-piece and for holding it in its place. Furthermore, the invention consists in a novel construction ofthe fuel-reservoir by making the lower part or throat that, on said curtain-like portion being turned, allow of its detachment and removal, and this by a certain arrangement and enlargement of the doors of the heater or stove without disturbing the structure generally. This provides for the ready replacement, by a new throat or portion when required, of that part of the fuel-receptacle in base-burning heaters and stoves which is the soonest destroyed by the action of the lire.

Referring to the accompanying drawing, A represents the upper part of the body of the heat er; B, the fire-pot or chamber; C, the grate;

and D, the ash-pit. E E is the fuel-reservoir. F is the main escape-pipe or iiue for the products of combustion. This pipe is connected in a direct manner, as by a branch, b, under control of a damper, c, with the body A of the heater, to provide for a direct draught on starting the re, and at other times when required. Said pipe F is also connected with the base G, which forms a flue round the ash-pit, and is in communication above, as hereinafter described, with other uptakes used in the regular or indirect draught.

To circulate the products of combustion for the heating of the air, either to warm the apartment in which the heater is placed, or to distribute it by suitable ducts to other apartments, the products of combustion, on turning the damper c, are made to lirst pass into upper-side pipes H forward of partitions d, and then to descend down dippipes l to the base G, through which they pass to up-take pipes J and to the main escapepipe F, the up-takes J connecting at their upper ends back of the partitions d with rear extensions ofthe side pipes H. This arrangement of pipes obtains a most effective and economical heating-surface without iinpairing the draught.

The air to be heated is introduced by holes e, in the bottom plate of the base G, to air-heating chambers L, and, after being warmed, passed out through corresponding holes f in the top of the base, for circulation among and around the pipes H I J, and other exterior radiating surfaces ofthe heater. These air-heating chambers L are situated within the base G, and so arranged as to be exposed on their sides in a direct manner to the heat of the base-flue, and to radiation from the ash-pit of the heater. This double eX- posure effects a considerable warming of the air before its passage to or around the exterior radiating surfaces of the heater.

The front plate K of the hea-ter is hung and secured to its place by passing it obliquely in a backward Adirection at its bottom behind the lugs or projections g on the bottom plate of the base, and then swinging or passing its upper end over the top of the heater, where it is secured by a screw-bolt and nut, l1, to a projection from the top of the heater. This mode of introducing1 and attaching the front pla-te of the heater admits ot' its ready insertion behind the center ornament of the mantle-piece without damaging or disturbthe latter.

The fuel-reservoir is made in two horizontal parts or sections, E E', the lower one E of which is made in the form of a detachable curtain that is attached to the other section E by bayonet or other suitable fastenings, 1', so that said lower section, when damaged by the action of the tire, can readily be replaced by another like portion by simply turning it so as to unhook it from the upper section E, and removing it through the doors k of the heater, said doors being so ar Fcured by Letters Patent, is-

The combination of the side pipes H, dip-pipes I, 11p-takes J, air-heating chamber L, flue G, and escape-pipe F, all arranged with relation to the body A and lire-chamber B for operation, as shown and described.
