"Nov. 5, 1929. H. HERRENBRUCK STOVE Filed June 14. 1928 Patented Nov. 5 1929 UNITED STATES PATENT OFFICE HERMAN HERRENBRUCK, OF BELLEVILLE, ILLINOIS, ASSIGNOR TO ORBON STOVE CO.,

or BELLEVILLE, ILLINOIS, A

CORPORATION OF DELAWARE STOVE Application filed J'une 14 This invention relates to heating stoves of the type in which a stove is mounted in a supair is admitted to be heated by the stove and from which the heated air passes to the outside of the easing.

An object of the invention is to provide improved means for controlling the c rculation of the air into and from the casing in which the stove proper is enclosed. Another object of the invention is to provide means within the casing for damping or baffling the ascent of the heated air within the casing so as to regulate and control the circulation.

Another object of the invention 18 to provide a casing for enclosing a stove proper and provided with louvres in the walls, in combination with damping or baffling devices movable to positions between the stove proper and the walls of the casing containing the lonvi'es so as to prevent the rapid ascent of air between the stove proper and the casing walls having the 'louvres, thus retarding and deflecting the heated air through the louvres and closer to the floor of the room containing the stove.

Other objects will appear from the f0llowing description, reference being made to the drawing in which n a Fig. 1 is a vertical sectional view of a stove embodying the present invention andlooking toward the inside of the rear wall of the casing.

Fig. 2 is a view looking toward one of the lateral side walls of the casing showing the arrangement of one of the louvres- Fig. 3 is a perspective view of one of the guard devices for protecting the casing walls from the intense heat of the enclosed stove.

Fig. 4 is an enlarged sectional view, on the line 4l4 of Fig. 2, showing the louvre construction.

The front wall and doors of the casing are omitted from the drawing, as illustration of 1923. Serial'No. 285,245.

shown) and the top wall 45 form the exposed part of. the casing which is supported by legs 5. The upper portion of the rear wall 1 has an opening 6 formed through it to accommodate a stove pipe extending from the stove 7 enclosed within the casing. The opening 6 is surrounded by an inwardly extending marginal flange 8 which reinforces and strengthens the adjacent wall structure. The upper end wall 4 is provided with a number of bosses or thickened portions 9 which seat upon flanges 10 formed by inwardly extended por-' tions of the casing walls. Screws 11 pass through the wall flanges 10 and engage within the bosses 9, thus rigidly securing the top wall in connection with the vertical casing walls.

Each of the lateral side walls 2 is protected from the intense heat of the stove 7 by a liner device. The liner device for each of the walls 2 comprises a metallic plate 12 having a sheet 13 of heat insulating material, such as asbestos, attached to its outer side. These liners are supported from the flanges 10 by hooks 14L attached to the liners and engaging the flanges and are held in spaced relationship from the adjacent walls 2 by vertical channel members 15 and angular arms 16. The channel members 15 are attached to the liners and have their flanges extending outwardly toward the walls 2 with which said flanges may contact. plates 12 and are of angular formation so that they engage with the walls 2.

Each of the walls 2 is provided with a louvre window which may be made by splitting said walls horizontally and downwardly at the ends of the horizontal splits and bending inwardly the parts 17 defined by the splits and forming louvre boards or slats. While these louvre boards or slats 17 are shown as formed integral with the walls 2 it is obvious that they may be arranged otherwise, if desired.

The lower edges of the liners for the lateral side walls 2 terminate approximately as shown in the plane of the upper ends of the louvres, though this arrangement may be varied, if desired, without departure from the principle of the invention.

The arms 16 are attached to the For the rear casing wall 1,1 provide a similar liner similarly supported and provided at its upper end with notch 18 to receive the stove pipe or flue. The liner for the rear wall extends downwardly to a considerable cistance below the lower ends of the liners for the lateral side v-ralls and terminates above the air inlet openings 19.

My ini-ention comprises a damper or baffle for controlling anc regulating the ascent of tee enterin the casing through the open lower end frame and through the louvres and through the holes 19. These dampers or battles ma oe supported as desired and, as shown, said dampers or baiiies comprise a pair of plates 20 mounted on horizontal pivots in connection with the sides of the stove 7 toward the louvre walls 2. A feature is that tie plates 20 are supported by too stove proper and not by the casing. From one of these dampers or baffles 20 a chain 22 eX- tends over supports 23 and thence outwardly through opening 12% in the top wall a for manual engagement and operation. From the other damper or baffle 2-0 chain 25 e tends to sliding connection 28 with the chain 22 so that by drawing the drain 22 taut both dampers or haflles 20 will be moved to approximately horizontal positions in which their outer edges areclose to the louvre wall 2 and near the upper ends of the louvre. This prevents too rapid circulation of the air through the casing by retarding and baiiiing cie air entering the casing, so e air is retained in the casing for a on and becomes heated to a ate: degree. However, the heated air is permitted to rise at the front and rear of the stove 7 and to pass out through the perforated top wall l.

From the foregoing it will be seen that while the air may freely enter the casing it does not freely pass to the top of the casing at the lateral sides of the stove proper. A part of the heated air is deflected outwardly and downwardly because of the proximity of the louvre to the dampers 20; and the dampers or bafiles 2O retard ascend of the air until the air is properly heated so that a room may be more quickly and satisfactorily heated than if cold air were permitted to circulate through the stove casin The construction and arrangement of my improved stove may be varied within equivalent limits and in other respects than those specially mentioned. I contemplate such variations as may be found desirable or expedient and do not restrict myself unessentially in any respect.
