IMPRVBME'NT. 1N eooKINe-srovs.

TO ALL WHOM IT'MAY CONCERN: Y

Be it known that I, LUrnEnM. PARSONS, of Waukau, in the county of Winnebago, and` State of Wisconsin, have invented a. new and improved Ventilating Cook-Stove; and I do hereby declare that the following is a fu1l,.cle ar, and exactde'scription thereof, which will :enable others skilled in the artto make and usethe same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to anew and'improved method of Ventilating a room, and of 'supplying the necessary air t'o the burning fuel; andiit consists iu an arrangement of ilues, dampers, and pipes,.whereby the impure :tirV in the upper portion,-o'r i`roin theiloor of room,I is made 'to supply the fire, thereby preventing-the current oi' fresh and healthy air which Hows towards the stove tosu'pply the room from-beingdrawn oii', but which is retained for purposes'of respiration, as will be hereinafter described.

The drawing represents a' vertical sectionvof the s tove, showin-g the arrangement of the dues and plates, and the direction of the currents of air, Vas well as' the course o f the products of combustion.

B is the ash-pit.

` Gis the oven.

'D is the smoke-pipe; and

E is the Ventilating-pipe. t

The stove is of peculiar construction, but similar to what Ais known as the elevatedoven stove." TheV products of combustion pass around the oven through the ilues a, and it has the ordinary apertures through its top plate for cooking purposes, as seen at b. i l

F isa detachable platefapplied to thestove, and extending from it, as seen'in the drawing. It may be a sink, if desired, and it is removable at pleasure.

v '.lhe stove is supported ou the legs c c.

'lo supply thefuel in the e-box wit-utile necessary draught of air for purposes of combustion, I pro-l vide an air-Hue, G, beneath the dre-Hue a, whichis` connected with the air or ventilating-pipe E, and when the aperture in' pipe E,marked m, is closed, the current to feed the fire will How from thetp of pipe E, but when m is open, the currentfwill iiow from the floor. i t

The ventilating-pipc E extends from the door to the upper portion-of the room, as seer` `in the drawing, and, when desired, it rnay be turnedl by an elbow, and extend to the most distant portion of the room, from veither or both ends, or'under the Hoor-of the room. i

The heated gases and products ofrc'ombustonivould take their natural c'ourse through the flue a, around the oven, andup the pipe D to the chimney. This, ofcourse, wouldcause a current of air to pass up the pipeV `E, and through the ilue G to the iire-box, which it enters througlran aperture marked f, or it may be inade to pass into the ash-pit, through an aperture mark'ed g, by closing the damper S, and) pass up through the grate -in'to the iire-box. The protection jamb-plate, marked'L in t'le drawing, is made movable, by which the fire-box may be enlarged or diminished, an'd adap'tedthereby to winter Orsum-mer use.- i

The air, in passing through the `flue G, becomes heated by coming inicontact with the flue-plate J', and it enters the fire-box with-its temperature greatly raised. v

k is a damper, which does double duty. As represented in the drawing, it closes an aperture. through the plate J. By dropping it down, the ilue G,is closed, and the-current ofair isl made to follow the current of smoke through the pipeD. By this arrangement the current oi air can be cut oif from the tire without eheek .ing the current in pipe E.

i The'current `of air Hows through pipe E, and air-passage G, upon the Siphon-principle, and the air `can be drawn from the most remote portionof the room, either from the Hoor or adjoining room; but the-main ativantages-which I claim are supplyingV the fire' with the foul or vitiate'd air `of theroom, andretaiuingfthe v nowing current of fresh, pure air, for supplying the lungs'oftthe inmates of the house.

What I claim, and desire t secure by` Leiters P aAenib,- ie'- 1. The arrangement, asherein desseribed;A of the demper K, with Vrelation to the air-passage G, and o'vcri C, whereby the supply. of'oold :ni-r VYto the furnace A-is cut o, and drected'through vthe ove to reduce' the heat in the latter, arid thensu'pply of oxygen'te the re, as set forth. l

2. The arrangement of the air-supply ue G beeath the re-lue a of the steve, communicating with the furnace A through the ash-pit when the stove is usied wtzlrcoxsil, andthrough @he aperturef above the .fish-pit when used with Wood, and Wherebythe cold air is heated by contcb 'with the 'filete J bfre reaching the Fn-e; as herein shown and describedfor the purpose specified.'-
