IMPROVEMENT IN HEATING-STOVES.

Specification forming part of Leters Patent No. 157,121, dated November 24, 1874; application filed July 10, 1874.

T0 all whom 31% may concem:

Be it known that I, JOHN VVHEELER EL- LIOT, of the city of Toronto, Province of Ontario, Canada, have inventednew and nsefnl Improvements in Heating-Stoves, of which the following is a specification:

Inventors and manufactnrers have been for years and still are endeavoring to produce a cheap stove which Will extract the whole heat from.the fuel and convey it to the atmosphere with the least possible waste. Base-bnrncrs innnmerable have been designed With this 0l)- ject, and althongh some have proved so far snccessfifl, they all have one serions fault, viz., complication et parts, and, consequently, expensiveness in their construction. Bich men can, it is true, obtain a stove which Will, in time, save in fuel its great cost, but to the poor man this advantage is practically denied, as he is nnable t0 pnrchase so expensive an article. The object of my invention is to prodnce a stove possessing the main advantages of the expensive article, but so simply and cheaply constrncted that the poorest may secnre it. My invention relates, first, to an improvement in the manner of conveying, around the base of the stove, the smoke and heated air, and extracting therefrom all the calorie before permitting it to escape; and, secondly, in an improvement in the manner of adjusting or affixing the mica paper or lights around the body of the stove. The first part of my invention consists in having a three-way draft passage on the smoke-vent of the stove, With radiating-pipe proceeding from each branch. The pipe coming from one of the holes, at right angles to the stovc, is bent downward, and is arranged around the base of the stove, as shown, and finally enters the hole opposite toits starting-point, and commnnicatcs With the chimney, as hereafter specified. In the center of the draft-passage a valve is placed, and so formed that the draft may be directed either throngh the radiatingpipe, arranged around the base, or permitted to ascend straight up the chimney. By this arrangement, the full heat of the smoke is imparted to the atmosphere by radiation from the pipe kept close to the floor, which is the true principle of heating. WVhen a rapid drait is desired, the valve is turned which opens the direct passage to the chimney. An important featnre in this portion of my invention is, that it can be applied to any kind of stove. The second part of my invention consists in havin g small buttons or knobs on the mica lights, r

and having the openings for them so formed that they can be readily sprung into place. The third part of my invention consists in certain improvements in the grate or lire-pot of the stove, as hercinafter described.

In the drawings, Figure 1 is a sectional front view. Fig. 2 is a sectional side view. Fig. 3 is a sectional detail, showing valve. Fig. 4 is a plan, showing manner of attaching. mica. Fig. 5 is a sectional elevation, showing manner of attaching mica.

Like letters indicate like parts in each fi gare.

A is the base or table upon which the stove rests; A is the lire-pot. A is the dome or top of fire-pot. A is the fuel-feeder or rescrvoir. All these parts are cast separately and fitted together, as shown.- D is the circular grate, With fingcrs d, supported by the lngs d on the ash-pan chamber E. F is the radiating-pipe; F three-way tirait-passage; F escape-pipe. a is the skirting or shelf upon which the radiatingpipe F rests. E 18 the ash-pan. 'B is the mica. b s a knob riveted to the mica. 12 are vertical ribs, against which the mica fits. These ribs are on the inside of the stove, and are not quite as long as the opening, on either side of which thcy are. The space thus left is protected by the horizontal rib or lip on the outside of the stove top and bottom of the mica-space. By this formation it is possible to cast the top or dome of stove in one piece, leaving the mica-spaces clear without any fitting. It Will thns be seen that the stove can be 1nade very cheaply, consisting essentially of five principal parts, viz., the base or table A, ash-pan chamber E, firepot A top or dome of stove A, coal reservoir or feeder A each cast separatcly, but formed so as to come together withont mach fitting. The grate D rests on the lngs d, and can be easily turned aronnd by putting a poker between the fingers d,which act as a fence or gnard for holding the coal on the grate while the cinders are being removed. In order to prevent the fire-pot getting red-hot, it may be lined either with tire-brick 0,01 au inner castiron pot might be inserted. F is the threeway draft-passage on the smoke-vent a F is the escape-pipe, and Whieh 1eads down and around the base of the stove, as shown in Fig. 3. The escape-pipe F is closed by the valve G. This valve lies diagonally aoross threeway draft passage 13, separating the tWO parts. and causing the smoke to pass down the pipe F, as indicated by arrow, around the base near the fioor before it can finally escape through the pipe F, as also indieated by arrow. By this arrangement, the draft ean be ohecked and the consumption of fuel correspondingly redueed, while, by bringing the heated air and smoke around the outside of the stove, as shown, all the calorie is extracted from it in its passage through the radiatingpipe F before it escapes. Thns all the advan- J. W. ELLIOT. VVitnesses:
