3 Claims.

, This invention relates to furnaces and more particularly to the outer casings therefor.

The principal object of the invention lato provide a furnace casing composed of a. plurality of sections, some of which are interchangeable with each other so as to provide for readily varying the size oi the casing to accommodate difierent interior arrangements of the heat exchanger.

Another object of the invention is to provide a furnace casing of simple and economical construction.

A still further object of the invention is to provide a furnace casing composed of a plurality of parts, some of which are of identical construction.

These objects are attained by providing a front section, a center section, a back section, means detachably connecting the front and center sections together, and additional means detachably connecting the back and center sections together. The back section is so constructed that it is interchangeable with the center section when the latter is removed, thereby forming from parts of the larger casing a casing of smaller size.

These objects willmore fully appear in the following speciilcation, when read in connection with the accompanying drawings, wherein.:

Figure 1 is a front elevational view of a furnace embodying the invention;

Figure 2 is a side elevational view of the same;

Figure 3 is a top plan view of the furnace;

Figure 4 is a cross-sectional view taken on substantially the line 4-4 of Figure 2;

Figure 5 is a cross-sectional view similar to Figure 4 showing a modified form of the furnace casing formed by omitting a portion of the furnace shown in Figures 1 and 4;

Figure 6 is a cross-sectional view taken on substantially the line 6 6 of Figure 3;

Figure 7 is a cross-sectional view taken on substantially the line 1-1 of Figure 1; and

Figure 8 is an exploded pictorial view of one n corner of the furnace casing.

The furnace casing shown in the drawings is composed of a number of sheet metal parts I detachably secured together. Briefly, the casing ,i can be said to consist of five vertical sections,

a front section A, a center section B, a back section C, a front intermediate section D, and a rear intermediate section E. A11 of these sections are detachably` secured together. This particular construction provides a furnace casing such as that shown in Figures 1 to 3 wherein the heat exchanger proper is located in one part of the casing and forced air circulating apparatus, consisting of a blower, filters, and the like, is located in another portion of the casing, or by the elimi- Vnation of Sections B and E and the substitution of Section C for Section B a casing can be provided which holds only the heat exchanger proper. The details of the construction by which this desired result is obtained will more fully appear hereinafter. i

The front section A comprises a pair of identical front corner posts I0, a front top rail II, two identical corner caps I2, a front panel I3, and a door I4. The corner posts are of arcuate crosssection and are provided at their upright edges with laterally extending inwardly offset flanges I5 (see Figure 8). The fianges I5 are offset inwardly a considerable distance for a reason which will presently appear. At the upper end of each corner post I0 is a flange I6 also inwardly offset a distance approximately equal to the thickness of the sheet metal used in the construction of the furnace casing.

The front top rail II is provided at its lower edge with an inwardly offset flange I'l. 'I'his flange is offset the same distance as flanges I5 on the corner posts. At its upper' edge the rail I I is provided with a. vertical flange I8.

The corner caps I2 are identical with each other and are constructed as best shown in Figure 8. They are of generally spherical character and are provided at two edges with inwardly offset flanges I9. The flanges I9 are offset a distance equal to the thickness of the metal used in forming the casing.

The front panel I 3 is a rectangular sheet metal structure provided wtih flanges 20 about its perimeter. The width of the flanges 20 is equal to the distance that the flanges I5 and I1 are offset from the corner posts I0 and the front rail II. The panel I3 is provided with a relatively large door opening to provide access to the interior of the casing. The door opening is closed by door I4 hinged to the panel and provided with louvre-s to permit the circulation of air therethrough.

The corner posts, front rail, corner caps, and front panel are secured together by bolts or hardened screws inserted through the holes provided therefor. The upright edges of the panel I3 are seated in the grooves formed by the offset flanges I5 while the upper edge is received in the groove fonned by the flange I1. All edges of the panel I3 are flush with the outer surfaces of the corner posts and front rail. The ends of the rail, I I overlie the flanges I9 and lie ush with the exterior surfaces of the corner caps. The lower edges oi the comer oeps overiie the iengeg t@ on the corner posts. T us, it 'si-iii be seen that all exterior surfaces, except the door id, ei'e flush with each other.

The center section B is composed oi e. pair ci upright posts 2i oi generally chennebsbeoed cross-section provided with letersly extending snges 22 et its uptight edges. Secured to the upper ends o* the posts 2i is s cross rail having downwardly cul'ved end portions EG, the extremities of which ere inv/esdly offset et (see Figure 6). The side edges oi the portions 2li are offset inwardly to forni flanges Maz.

The beck section C is generelig,7 similar 'to tile front section i but has no door or doos opening. The back section comprises s. een of corner noem 2S identical with the coi-nei` posts iii, s rear top rail 29, two comer caps 3Q exsfstiy` like the cornes caps i2, and s beck panel.

This section is composed. of e pair of top side rails 353 oi genere-iv src-nete section, best shown in Figure 8. At their lower edges the rails Si? ere provided with inwardly ci?.- set iianges 34. At their upper edges are vertically extending flanges The rails 353 are se tired; to the front corner caps it and the downwardly curved end portions 2d of the :coils 2S by boite or screws. The front ends of the rails overlap the flanges i@ on the iront corner oeps iii ond thereby lie ush with the outer sin'feces oi the caps i2. The resi' ends oi the rails 3S also over lop snges Zta on the cross rsii end lie nosh with the exterior surfaces oi the end portions of rails 23.
