PORTABLE OPEN FIREPLACE AND HEATER.

Application filed January 28, 1927, Serial invention relates to improvements in heating devices for residences and the like, my principal ob ect being to provide a portable heating stove arranged in the form of an open fireplace, with which is combined an additional an: heating and circulating drum substantially as shown in my Patent No. 1,609,693, dated December 6th., 1926. By

of this portable device not only may the same be positioned at different places in the house, but the expense of installation of the air heating means in a permanent fire;

place, as was necessary in connection with the apparatus shown in said patent, is avoided.

At the same time manifold advantages of heating and circulating a. body of air,'1n

additio the fire n to that heated by convection from is retained.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for whichit is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference several indicate corresponding parts in the views j 1 is asectional elevation of my portable apparatus.

2 is a top plan of the same. 3 is a cross section on the line 3-3 1.

Referring now more particularly to the characters of reference on the drawings, the

device comprises a vertical casing 1 preferably of rectangular form supported a short distance disposed from the floor by feet 2. A centrally fireplace area is formed in the front of the casing and extends upwardly from the bottom to the top thereof. The side walls 3 of the fireplace area preferably converge inwardly somewhat,

tion al conforming to convenpractice. These walls are spaced somewhat from the adjacent side-walls of the casing so as to form vertical air chambers 4 on both sides of the fireplace and spaced therefrom. While the fireplace area itself extends from the bottom to the top of the caslng the front opening thereof is limited in height, by means of the front wall 1 of the casing, which extends downwardly from the top The thereof a certain distance. bottom of the casing in the fireplace No. 164,344. Renewed November 14, 1928.

area is preferably covered with a layer of brick or the like, as indicated at 5 to form a hearth on which rests a grate or fuel basket 6 of suitable character. Disposed behind the basket and extending the full distance between the walls 3 is a vertical air drum 7 of rectangular form and open on the bottom. The drum extends to a point a considerable distance above the bottom of the front wall 1, but below the top of the casing 1 and at its top connects with a horizontal drum portion 8 formed therewith and which extends toward the front of the fireplace. front end, which is some distance back of the wall 1*" the drum portion 8 connects with an integrally formed downwardly projecting extension 9 which terminates substantially at the same level as the bottom of the wall 1 but in spaced relation thereto. An air discharge passage 10 extendsfrom the top of the drum member 8 to the top of the casing, said passage being of considerablelesser width than the drum. In order to cause the air passing up from the bottom to the top of the main drum 7 to circulate through the portions 8 and 9 before entering the discharge passage 10, a partition 11 extends across the portion 8 substantially midway of the height thereof fromv the back of the drum 7 to divide said portion 8 into two vertically spaced passages. At its forward end the partition 11 is bent downwardly to similarly divide the drum extension 9 into two transversely spaced passages said partition terminating short of the bottom of the member 9, so as to provide communication between the aforesaid passages. j j

Projecting upwardly from and communicating with the casing back of the passage 10 is a flue 12 for the products of combustion from the fire, said flue having a suitable damper 13 of ordinary character therein.

By means of this arrangement it will be seen that the heat from the fire is imparted to the entire area of the adjacent air drum surfaces, setting up a circulation of air through the drum structure from the floor to the discharge passage 10. The gases from the fire to reach the fine 12 must pass around the front of the drum extension 9 and then move upwardly past the outside surface of the same and across the top member 8 on each side of the passage 10. The corresponding surfaces of these parts of the drum structure are therefore also heated somewhat, aiding of course At its in heating the air in the drum and maintaining a good circulation thereof.

A vertical adjustable shutter plate 1st is ar-- ranged between the walls 3 to close the front opening of the fireplace when desired, said plate at its upper end bein supported to the extension 9 by spacers on said plate, which ineans of this arrangement a circulation of air will also be maintained through the chainherd, the direction of such circulation being); at times upwardly from the openings 17, and at other times downwardly from the registers 16 and thence through the drum structure. This direction of movement the air through said side chambers depends upon the heat of the fire and. the consequent velocity of the air circulating through the drum. The air drum being at the back of the fireplace, the structure may be placed directly against an ordinary wall without danger of unduly heating the same, on account of the cooling influence of the air constantly passing up the drum and which prevents the back wall of the drum from becoming heated to any harmful extent.

From the foregoing description it will be readily seen that l have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction. of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention,

as defined by the appended claims.

Having thus described my inventionwhat I claim as new and useful and desire tosecure by Letters Patent is:

1. A fireplace comprisinga portable easing structure, a-fireplace area formed with said casing, and open to the front thereof for a certain distance from the bottom upwardly,

a flue leading from the top of the casing at the back, an air drum at the back of the fireplace area extending upwardly from the bottom thereof, said drum .col'nmunicating with the lets from the chambers at the-top, and passage means between the drum and chambers at the bottom.

2. A fireplace comprising a casing structure, a fireplace area formed in said casing and open to the front thereof, an air chamber between the back of the casing and the back of said area and extending from the bottom to the top of the same, air chan'ibers separated from the'first named chamber between the sides of the casing;' and said area, a common air intake for all said chambers at the bottom, and individual separated air out-lets from said chambers into the atmosphere of the room in which the structure is located at the top of the casing.

23. A fireplace comprising a casing, having back, side and front walls, the front wallt rininating short of the bottom of the casing to form an opening, a fireplace within the easing, an air drum. arranged behind the fireplace and having an extension depending above and forwardly of the fireplace and spaced from the front wall to form a flue from the fireplace, an outlet flue connected. with the first named fine a slidable shutter plate mounted to be moved to close the fireplace opening and movable into the first flue, spacers on the plate to engage t-he'inner wall of such firstfiue' to hold theshutter plate spaced therefrom. to allow the free egress of the products of combustion when such plate moved into the first flueto open the fireplace.

4. A structure-as in claim 3, the spacers flaring downwardly from the top edge of the plate.

In testimony whereof Iaifix my signature.

JOSEPH M; CESA.
