Application filed March 19,1926. vSerial N0. 95,985.

This invention relates to fireplaces, one of the objects being to provide a structure of t-his type so designed as to set up a circulation of warm air within the room intov which the fireplace opens, the construction of the device being such that it can be faced readily with bricks or other desired material so as to be built readily into a mantel or a chimney.

A further object is to provide a fireplace the fuel containing portion of which has a removable wall so that the same can be replaced should it become burned.

lWith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit`of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

Tn said drawings,

Figure 1 is a perspective view of the fireplace, portions thereof being broken away.

Figure 2 is a vertical section therethrough on the line 2-2 Figure 3.

Figure 3 is a section on line 3-3 Figure 2.

Figure l is a section on line i-4; Figure 2.

Figure is a detail view of the damper controlling` rod, adjacent parts being shown in section.

Figure 6 is a rear elevation of the damper.

Referring to the figures by characters of reference 1 designates the metal housing or casing of the fireplace, the same being provided in one wall with a fireplace opening 2 from the top and sides of which extend flanges 3 provided at their outer edges, with facing strips 4 preferably integral therewith. Air intake openings 5 are formed in the casing close to the bottom thereof and at opposite sides of the fireplace opening, there being an outwardly extending flange 6 above each of these openings formed, at its free longitudinal edge with a facing strip 7 or the like.

Side walls 8 are extended inwardly from the sides of the opening 2 and are connected by a back wall 9 which is preferably curved upwardly toward the top of the opening 2 and merges into the bottom wall 10 of an upwardly and backwardly inclined fiue 11. The top wall 12 of this flue merges into the top of the fireplace opening 2 while the side walls of the flue, indicated at 13, merge into the side walls S of the replace.

The liue 11 opens through the back 14 of the fireplace and is adapted to be closed by a damper 15 hingedly connected to the back 14C as shown at 16. This damper has an arm 17 extending laterally from its upper or free longitudinal edge and this arm is connected by a chain 18 or the like to an operating rod 19 having a series of teeth 20. This rod is slidable within a tubular guide 21 which is mounted within one side portion of the fireplace, there being a flange 22 partly closing one end of the tubular guide and adapted to be engaged by any one of the teeth 2O so as to hold t-he rod 19 against movement in'one direc-tion. Obviously by lifting the rod to disengage the teeth from the flange 22, the chain 18 can be paid out so as to allow the damper 15 to swing back wardly and downwardly to open the flue. By pulling on the rod 19 the movement of the damper can be reversed. Thus the draft through the fireplace can be controlled at will. For the purpose of facilitating the movement of the damper a weight 23 is preferablymounted on the outer or exposed face thereof.

The space at the sides and back of the fireplace recess 24 formed between the walls 8 and 9 constitutes a fresh air compartment 25 and overhanging this compartment is a deliecting shield 26 extending throughout the width of the interior of the fireplace. Upwardly and rearwardly inclined partitions 27 extend fr-om points close to and above the air inlet openings 5 rearwardly to the back of the fireplace casing or housing and constitute a connection between the outer sides of the said casing or housing and the side walls 8 of the fireplace recess. Arranged under the rear portions of these inclined partitions 27 are upstanding deflecting shields 28 curved toward each other and fitted against the back wall of the casing or housing 1. Inclined plates 29 may be mounted on the partitions 27 to constitute heat conducting and radiating members. The fireplace recess 24 has a removable lining 30 the back and side walls of which are adapted to fit snugly against the correspond ing walls 9 and 8 and to rest upon the bottom 31 of the fireplace as shown particularly in Figures 1 and 3.

` placed on the top of the fireplace and surroundv the flanges 34 the upper edges of which will be flush with the brick work. If preferred, however, a cover plate 36 can be mounted n the flanges 34 and provided with `f openings 37 designed to match the openings 33 in the top of the fireplace. This cover plate can be formed with depending flanges 38 at its sides and front for covering the adjacent brick work. Thus the plate 3G will cooperate with the top of the fireplace to provide an airspace 39 between -plate 36. Consequently said plate 36 will not become heated to a high-temperature because spaced from thetop of the fireplace. Therefore it is more desirable for use as a mantel top under some conditions than would be a solid brick covering on the-fireplace casing or housing.

Vhen fuel is burned within the fireplace recess 24 the hot products of combustion will flow outwardly through the flue 11, the draft being controlled by the damper as hereinbefore explained. The walls 8 and 9 andthe flue 12 will conduct heat to the fresh air contained within the compartment so that a circulation of fresh air will be set up, the cold air being drawn into said compartment 25 through the base openings 5 and flowing outwardly, when heated, through the openings 33. Thus a circulation of air will be set up within the room where the fireplace is located, the hot air rising to the ceiling and circulating throughout the room and returning, after being chilled, by way of the openings 5.

It will be apparent that b y utilizing a fireplace structure such as described, a room can be more readily heated than with the ordinary type of fireplace because of the increased radiating surface and the establishment of the circulation within the room.

The housing or casing 1 can of course be mounted in any way desired. It is preferred to set it on a concrete base with the back of the fireplace structure extending outside the wall of the building so that the chimney can be built from the ground up with a layer of bricks or the like, which is next to the building, resting on the top of the back portion of this housing or casing. For the purpose of strengthening the housing or casing where it receives the weight of a portion of the chimney, the flange 40 has been provided.

What is claimed is A fireplace structure including a casing having a fireplace opening and a recess back of the opening, there being a fresh air compartment between the walls of the recess and the walls of the casing, said compartment having an air inlet adjacent the bottom thereof and an air outlet at the top thereof, a flange surrounding the outlet, a cover plate supported by the flange and spaced from the top of the casing, a veneer upon the front and sides of the casing, means adjacent the fireplace opening and the inlet for supporting the veneer, and spacing portions upon said supporting means and upon the cover plate for lapping the adjacent portions of the veneer.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.

EUGENE P. MILES.
