- may be easily opened or disassembled. to give access to the warm-air chamber and to the heater, for the purpose of cleaning said chamber and for repairing the heater.

A further object is to construct said casing; in the manner of an adjustable frame and detachable or movable easing-sections co" operating therewith, whereby the casing structure may be adapted to meet readil various designs of furnaces.

It is my object also to construct a c; ring frame for carrying the above-mentioned .de

tachable sections, which frame, after said sections have been removed or moved from their normal position to give access to sub stantially the entire area of warm-air chamber, will support the furnace hood and its pipeconnections without causing derangement of same, this frame structure presenting an open web-like appearance.

These features cooperate in giving a furnacehaving high sanitary qualities and one which gives very efficient service because of the fact that it can be easily maintai ed clean and its air passages unobstructed; and further, one which reduces expenses in upkeep, because when repairing is needed for the heater it is accessible without the great expense of tearing down a fixed and integral furnace casing.

In furnace structures now in common use it is the custom to provide a casing for inclosing the heater, the casing of such an integral structure that when, because of various defects that occur within the casing ither to the warm-air chamber or'to the urnace, it becomes necessary to gain access to said chamber or to repair said heater an often difioultt and expensive task is prei because the fixed casingi structure riiustlbe torn down to repair the injuryim side and rebuilt again when assembling. For this reason the fact is prevalent that very few furnaces are maintained, in proper working order to give eiiicient service. And because of dust, lint and other dirt particles accumulating within the: varm-air chamber,

the passages. thereof become so restricted that the air circulation is greatly impeded, and more important, such circulation be cause of said dirt accumulations is reduced to a very unsanitary state.

In my improved furnace structure embodying novel features above set forth, it is evident that the defective features of integrally constructed casings and such as are diiiicult to disassemble, are entirely'eliminated.

in, the accompanying drawings: Figure l.

Fig. i is a detail sectional view taken on the line of Fig. 1. Fig. 5 is horizontal detail sectional view as taken on the line 5--5 of Fig. 1. Fig. 3 is a detail view in perspective of an end. of supportingbar.

The heater 6 of the furnace maybe of suitable structure and in this instance I have illustrated the heater with an associated furnace-front 7 having a fire-d0or 8 and ash-pit door 9, said furnace-front eX- tending from a base 10 to a horizontal top ring 11 which is partly supported thereby. The furnace-front has flanges 12 extending lengthwise at its sides, and a middle ring 13 has its ends boltedth eto, thus partly supporting said ring. Said top and middle rings are of similar construction, being shaped in cross-section with a vertical por tion 14 forming the ring, and an outwardly extending flange 15, the outer s des of the ring forming casing receiving faces. A plurality of vertical supporting bars spaced apart about the rings are interposed beitween the rings 11 and 13 anQ- ring i3 and.

This holding means is adaptedto secure the sections in place to provide a close fitting casing and on'e'in which the sections can be easily re mews; aiid it will be noticed that the outer has of thebars that receive the casingvsec: tions are coincident with the outer face of the rings 11 and 13, thereby permitting a continuous casing receiving face between said members. In some furnaces the furnace-front 7 does not extend up to the top ring; orpartition therefore the intermediate space ab e said front could be provided with; a'de'tachable section such as has been described. Attached to the inner sides of said-"sections are corrugated linings. 23 whichTprovidc dead-air space to break the chill or the outer casing.

, The manner in "which I have herein. shown the bars adjustable and the casing sections attachedv "thereto might be deviated .irotn to procure the equivalent result, and the sections might be hinged or provided with catch'ieu-gcag'cmcnts with the bars. It might be desirable to-el iininate the middle ring 13 thereby having but single bars extending humane hose to the top ring, or. have a portion er the casing of integral structure and =a-portion exendirig around the casing of sectional structure; and it is-evident that mosses sections can be made into a casing in such various forms as to suit the most diversified requirements...

In furnace, an outer casing including plurality. of spaced vertical supports, each having a socket therein at its opposite ends, said support being in supporting engagement with said casing-members by the latter being received in said sockets; whereby the supports may be moved sidewise upon lateral displacement, and casing-sections de; tachably, mounted and interposed between adjacent supports. i
