WALTER Barents, or nos'ron, MASSACHUSETTS,

L'IMPRQQVEMENTIN euassemhsa Specification forming part of Letters Patent-No. 4%,?842, dated April 19, 1864-.

.To apZZ'whom; it mag concern:

Be it known-that I, WALTER BRYEN'I, a resident of Boston, in the countyof S ufiolk' and State of Massaehusetts,'have invented anew and useful Improvement in Parlor-Grates or Open Fire-Places; and Ido hereby declare the same to befnlly described in. the-followring specification, and represented in the ac companyintfdrawings, of which--- Figure 1 is a front elevation of a fire-place of my improved construction. Fig. 2 is a ver tioal-and transverse section of it l; Fig. 3115 a --longitu'diual section of it,-t-he" plane of sectio'n being through the air-heating passage or' chamber surrounding thegrate; Fig. 4 is ancud riew of the vfire-place, while Fig; 5 is a vertical section taken through the slide-valve ing chamber. r

Theinature of my invention eousists iu an improved o ien'fi're-place, as constructed with an air-heating chainbefarrauged around its grate and the'jambs of the fact-space in man- "and air-induction openiugof: the said air-hat-- -:=ger, and provided with-an air-discharging pas sagearranged in front of'the grate, and so as to discharge air downward-out of the same and into the ash pit or chamber beneath the grate, as hereinafter explained. i

i In the drawings, A denotesthe main body of the fire-place, which is supported on a rectangular tubular case, B, 'yrhic'h'goes around and extends above theenti-rc grate 0 and .Tonhs part of thechainber or space a over it for the reception ofthe-fuel for combustion inthe grate, the remainder of the said space being formed by an upright 'gratefl), and the said body A. The fire-place is open in part, is provided with athroatfli}, in the usual way, and is supportedonan ash pit or box, F, which extends underneath and in front of the grate G. "There'is an air conduit, G, leading into the case B, such case and conduit being pgo'vided with'a'registervalve, H, 'bywhich the admission of the air into the cas'e'B may be regulated g at pleasure. Itis intended that the conduita: shall 'alsogcominunicate with the erternal atmosphere, so as to lead fresh air into the space 13. This 'air, after being'heated within this space or chamber, is discharged in a thin sheet out of an elongated opening or passage,

, promote its combustion much better than cold air will.- 7

It is intended that the part ofxthe'ash-box which projects in frontof the case B, shall be covered over by a-plate, as shown at c.

Thealir by circulating through the air-heat ingchamber, serves to abstract heat fromLits I sides, and thus prevents the fire froth destroy iug the ease, or, in other words, renders the case more durable under the action of the tire;

Furthermore, the arrangement of the eduction air-passage b is such as to cause acurrent of air, while passing therefrom to operate to intercept and force back underneath the grate anylight ashes, whieh, falling from the grate, would be likely to b'ehlown or come outof the ash-box.

Iam aware that stoves haveheen made with air-heating chambers and means of discharging into the fuel air heated within such charm bers. Therefore I do not claim such as my invention, which has reference to an open fire place of the kind specified.

What I claim is--' i The} abovedescribed improved open fire place, as constructed, with the air-heating chamber arranged about; and so as to extend above its grate and the ash pit or box, and open into the latter, in mannera-nd so'as to operate substantially .as herei-nb'efore explained.
