Application tiled January 28, 1908. Serial No. 412,965.

To all when?, 'it may conce/m:

Be it known that I, J .mrs S. WVooo, a citizen of the United States, residing at Bristol, in theV county of Sullivan and State of 3 Tennessee, have invented certain new and useful Il'nproveinents in Grates; and I do declare the' iollowinr to be a full, clear, and

'false draft to the chimney.

exact description ot the invention, such as vwill enable others skilled in vthe art tok which it` appertains to make and use the same.

My invention relates to fire grates.

The object of the invention is to provide a device of this character which will be simple in construction, cheap to manufacture. and withal neatin appearance.

A further object of the invention is to provide means upon the grate and surrounding the grate which will deflect the fresh air, with its abundance of oxygen, to a point at the hack of the grate where combustion takes place. This construction gives increased efficiency and prevents excessive use of fuel. It is therefore more economical than former grates.

With the foregoing and other objects in View, '-lhe invention consists of certain novel features of construction, combination and Varrangement of parts as will be more fully described hereinafter and particularly point ed out in the appended claims.

In the accompanying drawings, Figure 1 is a front elevation oi' the device parts beine' broken away; Fig. 2 is a vertical sectional View thereof; Fig. 3 ,is a sectional plan View; and Fig. i shows a. modification.

"Reiarring more particularly to the drawing, l represents a casing which is secured in the chimney place, :1in any suitable manner, and is provided with an outstanding flange, 2, upon its vertical sides, and a vertical flange, 3, extending above thc top. These flanges are for the ,purposeof overlapping tlie briokwork, A, and preventing 'lhe casing rests directly upon the hearth, fl, and has an impcrorate top extending to a point adjacent tjhe vertical Hnge, Where it is cut away to forni u fiue-o['ening,

'The grato proper is supported upon ings, and 'ou'ipriscs u frame, 7, having' recesses is :it in', adjacent lny foiivurd #uil thereof, io rmcizivo tho Intl-rally px' ,-ji^izting;' studs. 5L o? the grate, it). Those studs uro positioned on 'the grate adjacent its forward edge so f-i ,that the rear puri, oi' the grato contains thc most metal, and is, consequently, heavier than the forward art, the grate being thereby unbalanced. o support it in a horizontal position, I provide `laterally extendinv lugs, 11,' projecting from its rear end an adapted to rest upon the frame, 7. This construction prevents the grate from dumping in, the back'and insures a front dump. The rear member, 12, acts in conjunction' with the grate proper and the back of the casing to form a flue, 14, which directs the pure air to a point, where combustion takes place.

y4` following the course of the arrows, a, it will be seen that the` pure air is carried back to a point of combustion, and with thesuioke travels as indicated by the arrows, I, the radiation bein from the back of the casing, l., out over t 1e rc proper -into the room to be heated.

In the modification shown in Fig. 4, a construction is shown, with lateral lugs, 15, .projecting outwardly from the side of the casing, 1, for sup orting the grate frame. l'n this instance, tie legs, 6, are dispensed with. Secured to the frame by the lugs, 23 is a front plate 16, composed of a series o vertically arranged bars, 17, and horizontal hars, 1S, which form with the intermediate bars, 19, apertures, 20, through the lower end of which a shaker is held to stir u the tire. This shaker is held in place y `a U-shaped bend in its body and projects back suticiently far tdi-cach the flue, 14.

As shown in Fig. 2, the fuel feeds over into the fluo, 14, Where it may be raked down by the shaker, 2l, and as the draft to the fire is from the front to the back, the fuel iu thc flue, lli, is heated to incandescence and draws oxygen to it much morerapidly ihau the remainder of the tire. This causes combustion to take place in the back of the l -jratc and the casing at this point to more quickljy absorb its full amount of heat and .start to throw it oft' into the room. With the cchclon formation of top casino', the heat is also radiated from the hack andfrom tlio rist-rs in the top directly out into the ))lll have shown an echelon formation of top 'or the casing' l, in the modification, but 1t will lio understood 'that may use any form ol whine; that may be deemed desirable.

Many rondini-ations may be resorted to in port iro without departing fromthe Scope of the claims, endl contemplate such changes and consider them Within the purview/'of the appended claims.

From Jdie foregoing description, taken in connection Wih the accompanying drawings, the constiuction and operation of' the invention will be readily understood Without requiring a more extended explanation.

Having; thus described in invention, Wha l claim as new and desire to Secure by Letters-Filtern, is: i

l. In n device of the class described, a chimney well having :L recess und n fine coininunicnting; therewith adjacent the forward side oi' n chimney Wall, n frame, a` fuel snppoi-t carried thereby, uv supplemental fuel snppoi']integral with tie freine and y pending` therefrom in the rear of Said tiret,

named Support, and a casing surrounding tion depending from the plane of the frame and having a plurality of apertures, and a Shaker passing through one of said apertures and pivotally connected to said front fuel support.

nln'l'e und adapted to Wollcin the'dependingl ln testiinonywhercof l have hereunto set" myhund in presence of two subscribing Witmesses.
