SPECIFICATION formingpart of Letters Patent No. 785,401, dated March 21, 1905.

Application led February 17, 1904. Serial No. 194,088.

To @ZZ whom, it may concern,.-

Beit known that I, GEORGE W. BUCK, a citizen of the United States,residing at Louisville, in the county of J eterson and State of Kentucky, have invented certain new and useful Improvements in Fireplace-Heaters, of which the following is a specification.

This invention relates to openfireplace heaters.

The object of the invention is to improve the construction of open-fireplace heaters by making' a movable mainly metallic structure adapted to enter the brickwork space as usually prepared, which structure contains within itself the draft-fines, dampers, grate, &c.,

substantially as hereinafter described and claimed.

Figure 1 is a front elevation of the improved iireplace-heater. Fig. 2 is a top plan of the iireplace-heater, and Fig. 3 is an end elevation thereof. Fig. 4 is a vertical central section looking in the same direction as in Fig. 3. Fig. 5 is aperspective View of the back flue-cover removed. Fig. 6 is a front view, Fig. 7 a vertical section, and Fig. y8 a rear view, of the fireback. Fig. 9 is a perspective view of the tirebaclr-support.

Let the numeral 1 indicate the body or shell of the heater, which is of metal and may be either a single casting or may be made up of separate plates, as is common in stove construction. This body or shell is open at the front and at the top, and the face-pieces 2 2 may be ornamented in any suitable way. The cap-piece 3 joins these face-pieces, and when the heater'is set this cap is usually under the mantel, the face-pieces 2 extending in front of the masonry of the fireplace proper.

The body or shell preferably flares towardY the front, and a grate 4, of any usual or convenient construction, is applied to the body and supported on lugs 5 5 or in any other usual and convenient way.

Directly back of the grating and in front of the back plate of the shell I place the fireback 6. This iireback is a very important part of the invention. It is preferably of iire-brick and is so constructed as to be entered from the iiaring front of the body and can be readily replaced by removing the grate 4.

vThe fireback 6 has a number of vertical grooves 7 in its face. These grooves 7 furnish downdraft-passages in rear of the grate, as clearly shown in Fig. 4.

The reback 6 rests on a bar 8, which rests on lugs 9 in the shell or body or is otherwise suitably supported.

The bar 8 has notches 10 in its front face, which register with the grooves 7 in the face of the iireback.

The rear face of the iireback 6 has vertical grooves 11, which are preferably less in nurnbcr and greater in depth than the grooves 7 in the vfront face of said tirebacl. The bar 8 has notches 12,corresponding with the grooves 11 of the fireback, so that when the fireback rests on bar 8 the grooves in each face of said fireback are continued through the supporting-bar, which thus becomes aprotector for.

the corners of the projections between the grooves at front and rear of said iireback.

The back plate of casing 1 is preferably grooved or corrugated, as at 13, to correspond with the grooves in the firebaclr, so that the fireback 6 and the back plate of the shell or casing have between them a series of small lues composed of the grooves 11 in the fireback, continued through notches in the supporting-bar, and the grooves 13 in the back plate of the shell proper.

Above the fireback 6 and within the shell or body 1 the deflector 16 is placed. This deflector is preferably of fire-brick and extends entirely across the shell 1, the ends of the deiiector resting on the top of the side plates of the shell. The front of the deflector is preferably convex, as shown, and the top of shell 1 is formed to correspond. The deiiector thus occupies an oblique position on the rear upper portion of the shell.

The Hue-plate 17 is a metal piece, preferably cast, and having ribs 18 extending from the front face. These ribs rest on the inclined rear face of the deiiector 16 and form (with the rear side of the deflector) lines or passages 19, which are continuations of the iues or passages 11 in the fireback.

In the rear face of the deector there is a groove 20, which forms a rest or fulcrum for the rear damper 21. Said damper 21 can be turned down over the top of all the ues or passages 19, thus cutting olf ,the draft, which is a downdraft from the fire, through such lues or passages.

Assuming the damper 21 to be open, as in Fig. 4, it will be seen that smoke and the gaseous products of combustion may pass down through the grate and also down the grooves 7 and passing under bar 8 may turn up the grooves or flues 12 and continuing through passages 19 may escape up the chimney in the direction of the arrows, Fig. 4. The same passage serves as a passage for ventilation from below the grate; but when damper 21 is closed this downdraft and ventilation is stopped.

I find that by breaking up the space between the iireback and the back plate of the shell or body into a number of small passages a more efficient draft may be obtained than by a single large passage in the same location, and the structure is stronger, as the parts mutually support each other.

The Hue-plate 17 is preferably constructed with wings 24, which wings overlap the ends of deflector 16 and hold the same in place. Flue-plate 17 can be held to the shell by suitable screws or bolts, as 25, or in other usual manner for securing' stove parts together.

The damper 21 is held down by lug's 26, which project from the flue-plate in the proper position.

The top damper 30 is pivoted in lugs 31 on the body and extends across the open top of the shell or body 1. This damper has openings 33, which -may be closed by slide 34, held on top of the damper by lugs 35 thereon.

A handle rod 36 extends from slide 34 through an opening in the cap-piece 3 of the heater, and a handle 37 thereon permits the operator to slide the piece 34 backward or forward, thus opening or closing the holes 33.

The damper 21 has a lever-arm 39, which is provided with acounterweight 40. Arm 39 is connected by a pivoted link 41 to a stud on damper 30, so that when damper 2l is closed down the damper 30 will be lifted at its rear edge, the counterweight 40 serving to hold the dampers in any adjusted position when assisted by the friction of the parts. The handle 37 can therefore be manipulated to lift damper 30 at its rear edge and close down damper 21 simultaneously by a downward pressure on said handle or to reverse the operation by an upward pressure. It is desirable that both dampers 21 and 30 shall not be closed at the same time, as gas developed in the stove must then escape into the room; but when damper 21 is open and damper 30 closed the same eect as of lifting damper 30 may be caused by sliding the slide 34 forward, thus opening the upper or directv draft and the rear or down draft at the same time.

Except as pointed out in the claims I do not limit myself to precise forms or constructions, as the general features of this heater are applicable to many forms of fireplace-heaters.

`What I claim is- 1. In a fireplace-heater, a metallic body in form of an open box,the back plate of said body having grooves extending in a generally vertical direction, a grate in said body, a lireback in rear of said grate and in front of said back plate, said lireback having vertical grooves in its front and rear faces, a bar extending across the body beneath said back plate and having grooves in its front and rear faces, and an inclined deiiector above the fireback, all combined.

2. In a fireplace-heater, the body or shell, a

grate therein, a fireback of fire-brick in rear of the grate and provided with a series of passages in its rear face which rests against the back'plate of the shell, and a metallic supporting-bar for said fireback having notches corresponding to the grooves in the fireback, all combined.

3. In a fireplace-heater, the shell or body, a

`iireback therein having vertical passages in its rear face next to the back plate of the shell, a deflector-plate above said fireback, and a Hueplate having' grooves in its face and forming, with the del'lector, flues which are continuations of the passages in the tlreback.

4. The combination with the body or shell, the freback, and the inclined deflector above said iireback, of a ribbed flue-plate resting on said deector, and having wings extending over the ends of the defiector.

5. The combination with the body or shell and the inclined deiiector thereon, of the iiueplate having ribs on its front face and forming with the deiiector a series of flues, a dainper over said fines, and a dainpcr in front of the deliector.

6. The combination with the body or shell, the inclined deiiector, and the flue-plate having grooves and forming with the defi ector a series of flues, of a damper having its fulcruln on the deiiector and extending over said flues, a second damper hinged at the front of the shell and extending back to the deflector, and a link connecting said dampers so that one lifts as the other falls.

In testimony whereofI affix my signature in presence of two witnesses.

GEORGE W. Buon.
