SPECIFICATION form-ing part of Letters Patent No. 588,884, dated August 24, 1897.
Application filed July l2, 1895. Serial No. 555,760t. (No mcdel.) I
T0 all whom t nul/y concern:
Be itknown that I, HOWARD DE WoLFE SAWYER, of Revere, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Downdraft Cooking and Heating Stoves, of which the following, taken in connection with the' accompanying drawings, is a specification.-
The object of my invention is to provide a cooking and heatingstove or range in which the draft is downward through the 're and through its supporting-grateormed of watercontaining tubes supplied from below with water which rises from the grate between the fire-pct and oven and by its circulation serves to heat adjacent rooms. The caloric-current after thus descending passes under,upwardly, beyond, and over the oven, thus entirely en,- circling it and heating, last of all, the top, through which griddle-holes are formed. Water-walls and bottom are provided for the -iire-pot and combustion-chamber and flow and return pipes afford constant circulation for the water. Supply-pipes lead obliquely upward beneath the oven and connect the eXtreme innerend'of the water-bottom with the bottom portion of the water-back, which stands vertically between the lire-pot. and
oven. Fuel is supplied through griddle-holes over the water-grate. An open air-space may be interposed between the oven and the combustion-chamber or other partof the caloric- .draft being assured.
passage t0 temper the heat, if required. A
broiler-openin g through the front wall is pro-- vided at the line of the top of the fire. The
fumes of cooking are drawn downwardly into v the ire. An ash-door near the bottom permits necessary. cleaning out. A horizontal recess in the front wall of the fire-pot and furnished with a door permits ready insertion of the grate-tubes and their supply-pipes and affords space for movement of the water-box due to expansion or contraction of the parts. The grate may, however, be arranged otherwise than as herein illustrated, the downward The walls, the bottom, and the grate and supply-pipes being all filled with water and exposed to the heat sim ultaneously, expansion will be practically uniform, and the tubes may run from wall to wall obliquely to promote active circulation.
darts.)
The ire-boxwith its back and walls and the water-bottom with tubular water-passages from its tip to the lower part of the waterback may be cast in one and used integral in heaters of proper size. f
In the drawings, Figure l is a vertical longitudinal section through one of my improved stoves. Fig. 2 is a perspective detail, in section, of the re-box and water-bottom de tached and somewhat modified in form.
The central feature of my stove or range is the oven A, surrounded by the tire-pot B and the continuous passage C C for the caloriccurrent. (Shown in Fig. l and denoted by the The hollow bottom D and vertical walls E are filled with water, as is the waterback F,in terposed between the fire-pot and the oven, the entire water-space being connected for free circulation.. The grate Gand its supply-pipes l-I enter the water-back F, and converging, as shown, both enter the water-box J, which extends horizontally across the front of the stove, but is free from contact with its walls, thus giving freedom of expansion and contraction and providing for active circulation of the water therein.
The water-box J occupies a recess in the front wall of the stove, in which it may move slightly and throughl which the grate-tubes Cr and supply-pipes II may be first introduced in setting up the stove. A door] may close this recess tightly in the front to prevent entrance of air or escape of gases.
Beneath the oven pipes K run obliquely from the lower end of the water-back F to the inner end of. the hollow bottom D,where they enter a turned-up foot or boss d, intowhich their ends are screwed, so that the water may rise therein and circulate freely as it becomes heated by the high temperature of the burn- IOO and over the oven to the funnel L. r1`he foot (Z is preferably a transverse shell covering an opening at the tip of the water-bottom D and bolted in place.
In view of the great heat produced by the downward draft under the arrangement shown I provide between the oven and the passage C C an air-space M, into which nrore or less of external air may be admitted th rough openings O, controlled by suitable slides. A hot closet P, adjoining the upright passage C, is abundantly heated by the current impinging on the end wall and rising in said passage.
Griddle-holes with suitable covers Q are formed over the tire-pot B and oven A, the first of these constituting the draft-opening above the fire. A broiler-opening R may also' be formed just above the tire-level in the front wall. This may serve to admit the draft when the griddle-holes are occupied by kettles or otherwise. The ash-door U opens through the front wall into the combustionchamber beneath the grate for removal ot' ashes.
My stove or range is of great utility fo'r heating adjacent rooms by hot-water circulation. To promote this, I extend flow-pipes S up'- wardly from the top of the water-back F within or near to the funnel L, so as to utilize the' heat remaining in the caloric current. Such pipes S run to radiators in the various rooms to be heated and return thence to the lower part o1' hollow bottom D through returnpipes T.
I am aware that in the patents to Easterly, dated February 13, 1855, reissue No. 3,010, June 80. 1868, and to Field, dated July 19, 1859, No. 24,800, magazine cooking-stoves are shown having a' fuel-chamber external to the shell or body of the stove, with draft-inlets through such external chamber and tubular grates at the base thereof level with the stovetop and not connected with any water-walls in the fire-box or stove-body; and also that in the Backus patent, No. 132,129, dated October 15, 187 2, water-walls are' shown without water-grate or downward draft, and in the Dewey patent, No. 70,077, dated October 22, 1867, water-walls without downward draft and a water-grate without circulation thro ugh it are shown. In the Backus and the Dewey patents the oven is outside of the stove-body proper. I therefore disclaim all these prior constructions, each one failing to embody the combination and arrangement of parts which renders my stove so effective.
I claim as my inventionpot within the stove-body and having waterwalls', a tubular water-grate therein and a draft-inlet above said grate, and with a caloric-passage from such tire-pot extendingy beneath, beyond and over the oven', substantially as set forth. I
In a downdra'ft cooking and heating stove, the interior oven and the' caloric-passage surroi'inding said oven, in combination with the fire-pot having a water-back with water-grate connected thereto and a waterbottom extending beneath the oven, and with inclined water-pipes beneath the oven within the caloric passage and connecting the extension of said bottomv with the water-back, substantially as set forth.
4. In a downdraft cooking and heating stove, the oven A, inclosed within' the shell or body of the stove proper, and the heatpassage C C C encircling the oven,- in combination with the fire-pot having a water-bottom and water-back, an in'closed water-grate communicating with said water-back, a draftinlet above said grate whereby a downward draft is assu red, and flow and return pipes for hot-water circulation to adjacent rooms,- substantially as set forth.
5. In a downdraft heating apparatus, the tire-pot having a water-back and a' tubular water-grate communicating therewith and extending forward therefrom, in combination with a draft-inlet above the' grate, a waterbottoin beneath the grate and fire-pot and running rearwardly beyond said water-back, and a tubular connection between the tip of said water-bottom and the lower part o'f the water-back, substantially as set forth.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 25th day of June, A. D. 1895.
HOWARD DE "OLFE SMVI'ER.
