OIROULATING HEATING STOVE.

Application filed March 23, 1928.

The invention relates generally to circulating heating stoves and more particularly to stoves ofthis type in which the heating unit is enclosed in a concealing cabinet preferably adapted and constructed to present a finished and ornamental appearance.

One object of the invention is to provide a new and improved cabinet for enclosing a heating unit which embodies a closure means therefor'of a simple and practical character movable to an out of the way position to permit access to the interior of the cabinet for operating purposes. 7

Other objects and advantages will become apparent in the following description and from the accompanying drawings 1n which:

Figure 1 is an elevational view of the invention, parts thereof being broken away to disclose the operation of the closure means. r

Fig. 2 is a fragmentary view in perspective taken from the interior of the cabinet looking outwardly.

Fig. 8 is a fragmentary view in elevation,

looking laterally from the interior of the cabinet, of one of the closure sections in open position.

Figs. 4 and 5 are enlarged fragmentary detail views in section and plan respectively showing the upper guide bar and follower.

Figs. 6 and 7 are enlarged fragmentary side and face views respectively showing the construction of thelower guide rails and rollers.

WVhile the invention is susceptible of various modifications and alternative constructions, I have shown in the drawings and will herein describe in detail the preferred embodiment, but it is to be understood that I do not thereby intend to limit the invention to the specific form disclosed, but intend to cover all modifications and alternative constructions falling within the spirit and scope of the invention as expressed in the appended claims.

In the drawings a cabinet, constructed in accordance with the objects of this invention, is shown as comprising generally an upright outer case or cabinet having a top 10, bottom 11, and a front, back and sides. If desired suitable legs 15 may be employed to space the cabinet from the floor. The cabinet is of a size to enclose a suitable heating unit or stove, generally designated as 16, which may be of any preferred con- Serial No. 264,154.

struction and design. The cabinet may be as ornamental in appearance as is desired and preferably the ornamentation is of such character that designs in grille work 17 or the like may be employed. Thus a free circulation through the cabinet, of air to be heated by the stove mounted therein, is insured without detracting from the appearance of the cabinet.

As shown the stove is mounted in the cabinet with the fuel and ash pit doors 18, 19, which are customarily provided in such stoves, facing toward the front of the cabi net. In order that access to the doors 18, 19 may be had, the front of the stove has an opening, the margins of the opening being defined by a frame 20 which may be formed as an integral part of the front or may be rigidly affixed thereto. Preferably the upper edge of the frame is turned inwardly to provide a short flange 21 (Fig. 4) the purpose of which will become hereinafter apparent.

In the present embodiment the preferred form of closure means (Figs. 1 and 2) comprises a pair of flat substantially rectangular doors 22 which are adapted normally to extend across and completely close the front opening of the cabinet. A simple form of means for insuring that the doors assume the proper position in the frame and for providing rigidity between the doors comprises an offset lug 22= projecting laterally from a position near the top and bottom of the inner edge of one of the doors, which lug is adapted to engage a complementary boss 22 formed in proper position upon the other door. Any suitable form of operating handles 23 may be secured in the customary manner upon the doors 22.

The means by which guided movement of the doors is attained comprises, in the present instance, a pair of guide wheels, generally designated as 24, mounted near the lower edge of each of the doors, which wheels engage suitable guide rails 30, 31 shaped properly to direct and guide the movement of each door. Means also is provided on each door to support the upper portions thereof during the opening and closing movements.

The guide wheels 24 may be of any suitable form, and in the present instance comprise grooved rollers 25 (Figs. 6 and 7) each of which is pivotally mounted on an L- the cabinet is simple.

shaped bracket 26 which carries a vertically extending rod 27. The rod 27 is journaled in both legs of a U-shaped bracket 28, which in turn is rigidly fixed to a pair of lugs 29 suitably mounted upon the door. Thus, each of the rollers 25' is spaced inwardly of the cabinet from the doors, and are mounted in such manner that relative pivotal movement is permitted.

The guide rails 30, 31 are in the form of tracks provided for each door and are mounted upon the bottom of the cabinet in a position to be engaged by the grooved rollers 25. As may be seen in Fig. 2, four guide rails are shown, there being a set of two rails for each of the doors. The inner rails 30 of the sets are appropriately formed and positioned relative to the doors so that as the inner rollers follow the rails the inner side of the doors will move in a substantially straight line laterally of the cabinet. The outer rails 31 are curved so that as the outer rollers follow the rails the outer side of the doors move first diagonally inwardly a short distance and then swing rearwardly to occupy a position near the rear corners of the cabinet.

TMeans is provided for guiding and supporting the upper portion of the doors during the movement thereof. This means, in

the present instance, comprises a guide bar 32 (Fig. 4) secured to a plurality of lugs 33 which space the bar rearwardly from the front of the cabinet with the bar extending laterally across the cabinet substantially in registry with the margin of the upper edge of the frame 20. Each of the doors carries an upwardly extending follower herein shown in the form of a finger 34, which is rigidly secured to lugs 35 preferably positioned near the inner upper corners of the doors. The fingers 34: on the doors are adapted to be inserted between the inwardly extending flange 21 on the upper side of the frame 20 and the guide bar 32 for guided sliding movement therebetween.

'The operation of the closure means for Assuming that the doors are in closed position and that it is desired to open them, it is only necessary to grasp the operating handles 23 and toexert a force acting to separate the handles.

Such a force will cause the outer edges of the doors to move diagonally inwardly a short distance, and then as the outer rollers follow the guide tracks 31, these edges of the doors will be swung sharply inwardly of the cabinet. At the same time the inner edges of the doors have been guided by the inner rollers upon the inner guide rails 30 to a posltion adjacent the front side of the cabinet. Thus in the open position of the doors only the inner edges thereof may be seen. By'this construction it will be apparent that a closure means for the front opening way position at the sides of the cabinet when it is necessary, for any reason, to obtain ac cess to the heating element positioned in the cabinet.
