6 Claims.

This invention relates to a front or fixture for fireplaces.

An object of the present invention is to provide a unit which is readily attachable at the front of the usual relatively large opening of a fireplace of the open type having a grate for burning fuel, such as coal, wood, gas, etc., said unit including means for controlling the intensity larly being effective to prevent entry of dust and dirt into the room and to prevent drafty withdrawal of air therefrom when the fireplaceis not in use.

Another object of the invention is to provide a fireplace unit having the above described advantages combined with the features that maximum visual enjoyment of a fire in the fireplace may be obtained without certain physical discomforts usually attendant thereto.

Another object of the invention is to provide a device of the character described which eliminates the necessity for having the usual chimney draft-regulating means.

Still another object of the invention is to provide a device by which a fireplace having faulty flue construction may be quickly and economically adapted to provide the advantages of a fireplace of superior construction.

These and other objects of the invention will be manifest from the following brief description and the accompanying drawings.

Of the accompanying drawings:

Figure 1 is a front elevation illustrating the improved front or fixture in position in a fireplace opening.

Figure 2 is a cross-section taken on line 2-2 of Figure l.

Figure 3 is a cross-section on a greatly enlarged scale taken substantially on line 33 of Figure 1.

Figure 4 is a cross-section taken substantially on line 44 of Figure 3.

Figure 5 is an enlarged cross-section taken on line 5-5 of Figure 1.

Referring to the drawings, the numeral l0 designates a rectangular frame having relatively narrow top and side strips ll, l2 and I3 and a relatively wider bottom strip [4, the side and top strips being adapted to overlie the side and top edges of the usual fireplace opening (see Figures 2 and 3). The inner edges of strips ll, I2, [3 and M are formed inwardly in reverse bends to provide a relatively narrow recessed seat I5, defining a rectangular pening 16 which substantially closely proximates the full size of the fireplace opening. The lower edge of bottom strip l4 may be flanged inwardly at I 4a to enhance the support of the frame. The recessed rectangular seat portion l5 preferably is arranged with respect to the widths of strips l I, I2 and I3 of frame l0 so that the frame will readily fit in fireplace openings within a substantial range of sizes.

Normally seated against the seat I5 to fill opening 16 may be a pair of closure panels I! and i8 comprising rectangular frames l9 and 20 of metal or other heat-resisting material, which are U-shaped in section, and in which may be fitted sheets 2| and Zla of fully transparent glass or like material adapted to withstand relatively high heat from a heat unit in the fireplace, such as a coal fire in a grate F. Glass suitable for the present purposes is now available on the market under the trade name of Herculite, the same being manufactured by the Pittsburgh Plate Glass Company. The frames l 9 and 20 are relatively narrow to expose a maximum area of the transparent glass panels, so that a maximum full view of a fire in the fireplace will be possible. The panel frames i8 and 20 are suitably hinged at the outer edges thereof to the frame In, as indicated at 22 and 23, to permit swinging the panels to open position for purposes to be described later.

The panel frame l9 may have secured to the inner side thereof a vertical strip 24 providing a seat 25 for stop engagement by the inner edge of the panel frame 20. Suitable handles 26 and 2! may be provided on the inner sides of frames l9 and 20, as shown, to facilitate opening and closing the closure panels. Also, releasable locking means for retaining the panels in the normallyclosed position is provided by a detent or raised portion 28 in lower frame strip I4, at the center of the frame, over which the door panel frames l9 and 20 are yieldingly engageable, as will be readily understood.

To provide adjustable draft means operable when the closure panels are in normally closed position, there may be a horizontally elongated slot 30 in lower frame flange l4, over which oppositely disposed closure plates 3| and 32 are slidable from and toward each other in

parallel guide strips

33 and 33a secured to the back of bottom strip I4. Forwardly projecting knobs or

handles

34 and 35 are provided on plates 3! and 32 for shifting the same to adjust the size of the draft opening.

For anchoring frame ill in a fireplace opening there may be provided a plurality of self-adjusting anchoring devices 36. Each anchoring device 36 may comprise a hook member 31 engageable, for example, with a part of the brickwork or other structure of a fireplace, and yieldingly connected through a tension spring 38- to an eye 39 attached to the top of frame H1. 7 Similar anchoring devices may be provided at other parts of the frame ii] if desirable or necessary.

In the use or operation of the improved fireplace fixture, positioned in a fireplace opening as previously described, the closure panels I! and 18 are only opened on

hinges

22 and 23 to build or replenish a fire in the fireplace or for cleaning purposes. That is, the panels are normally in closed position. whether there is a fire in the fireplace or not.

When there is a fire inthe fireplace the draft, and. therefore the amount of heat and rate of burning thereof, is effectively controlled by shifting slide plates '3l and 32 to adjust the size of the opening through slot 33. The fire thus. controlled will burn uniformly at substantially any desired rate, as compared with the usual open fireplacein which the rate of burning is unsteady and unpredictable. Furthermore the transparent glass panels transmit the heat of the fire outwardly and substantially uniformly, by radiation, the only heat loss from the room to the fireplace being through the relatively small draft aperture 33,.and therefore being negligible. In addition, the transparent panels permit full view of the fire burning in the fireplace with attendant visual enjoyment thereof, but without the usual discomfort of an open fireplace caused by non-uniform heat emanating therefrom combined with cold drafty air drawn to the fireplace by the relatively large open draft thereof. It has been estab lished, for example, that an unshielded open fireplace draws air from a room at substantially all areas of the frontal opening, so that instead of heat being'transmitted tothe room from the fire in the fireplace, actually heat from other sources may be dissipated outwardly through the. fireplace and flue thereof.

When there is no'fire in the fireplace, the fixture in closed condition prevents entry of dust ordirt into the room, the slot 33 then being maintained closed, and at the same time prevents passage of drafty currents of air from the room to the fireplace. I'he improved construction, furthermore, eliminates the necessity for the fireplace having the usual flue draft damper, and makes possible full beneficial use of fireplaces having faulty, smoke creating draft means, which I might otherwise be unusable.

Thus has been provided an improved fireplace front or fixture of the character described which accomplishes the stated objects of the invention. Modifications of the invention may be resorted to without departing from the spirit thereof or the scope of the appended claims.
