AIR-HEATING DEVICE FORSUPPLYING HEATED AIR To BUILDINGS non CURING TOBACCO. y i

Application filed October 8, 1919. Serial No. 329,260.

To all whom it may concern:

Be it known that I, JOHN B; liflusn, a

citizen of the United States, residin at Cameron, in the county of Moore and State of North Carolina, have invented certain new and usefullmprovements in Air-Heating Devices for Supplying Heated Air to Buildings for Curin Tobacco, of whlch the following is a specification, reference being had thereinto the accompanying drawings.

This invention relates to a tobacco curing apparatus, and has for its object the 1mprovement of the construction of a furnace and its cooperating parts, whereby a comparatively small furnace can efliciently heat a large building by reasons of the novel structure ofthe furnace and its necessary cooperating pipes or flues.

Another obJect of the invention is the production of a tobacco curing apparatus which will evenly distribute the hot air throughout the building by reason of the peculiar positioning of the pipes, as well as other peculiar construction.

With these and other objects in view, my invention comprises certain other novel com binations, arrangements and constructions as will be hereinafter specifically described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claim.

In the drawings:

Figure 1 is a perspective view of the furnace or stove of my improved apparatus, while-- Fig. 2 is a longitudinal section of the same.

Fig. 3 is a sectional View taken on the line 3-3, Fig. 2, and looking in the direction of the arrows.

Fig. 4 is a section taken on the line t e, Fig. 2, looking in the direction of the arrows.

Fig. 5 is a plan view of the preferred embodiment of my apparatus.

Referring to the drawings by numerals, 1 designates a portion of a building in which tobaccco is to be stored for curing, and preferably at the front end 2 of the building 1 (Fig. 5) are positioned two furnaces 3. In Fig. 5 I have shown a diagram of two tobacco apparatuses, but it will only be necessary to specifically describe one, as they are substantially duplicates.

The furnace 3 comprises a body having sides 1 and at the bottom ofthe body is formed an ash pit 5; the body (Fig. 3) is supported uponbricks 6. The sides 4, com tiguous to thcash pit 5 are provided with inwardly extending flanges 7, which flanges support grate bars 8. At the upper edge of each 'side 4 is an outwardly extending flange 9. v

The top of the furnace comprises an inner curved plate and an upper curved plate 11. The edges of the inner plate 10 rest upon the top of the sides 4, (Fig. i) and the edges of the outer or upper curved plate 11 are flattened to form flanges 12, which flanges 12 fit snugly upon horizontal flanges 9 and these flanges are fastened together by suitable rivets or bolts 13. The outer plate 11 of the top of the furnace is corrugated, as at 14, intermediate its ends to provide a greater radiating surface. Between plates 10 and 11 is formed a hot air compartment 15. Near the front end of the outer plate 11 is an air inlet opening surrounded by a nipple 16 upon which is mounted a curved fresh air pipe 17, which pipe 17 is provided with a suitable valve 18 for controlling the passage of fresh air into the hot air compartment 15. r

A hot air pipe 19 has its inner end on a nipple on the top of the late 11 near its inner end within the building 1 and within the hot air pipe 19 is placed a plurality of small or auxiliary hot air pipes'20, which communicate with the compartment 15, the

inner ends of some of the pipes 20 rest against the top edge of the nipple engaged by pipe 19, and in the primary or outer pipe 19 are formed corresponding apertures 20*, one being the outlet for each auxiliary pipe 20 (Figs. 1 and 2) so that hot air is passed from the hot air compartment through the auxiliarypipes into the building at different points or locations, and some heated air is also discharged from the end of pipe 19, which end terminates short of the front 2 of the buildingl, as shown in the diagram building, discharging into a suitable stack 22. This smoke pipe 21 also serves to heat some of the air in the building 1.

lVhile I have described the preferred embodiment ofmy invention and have illustrated the same in the accompanying drawings, rertain minor alterations or changes may he found desirable in the extensive manufacture of my apparatus, and therefore, I reserve the right to make such alterations or changes as shall appear to one skilled in the art to Which this invention relates, and which fairly fall within the scope of the appended claim.

" What I claim iszi v A device of the kind described consisting of a furnace provided With a top including a top plate having a nipple formed thereon,

said furnacevprovided with a hot air compartment under said top plate, a fresh air pipe communicating at one end with said hot air compartment, a curved or bent primary'hot air pipe positioned at one end upon said nipple, a plurality of auxiliary hot air pipes within said primary hot air pipe and filling the same and some having their inner ends resting against the top edge of the nipple, and said primary hot air pipe having a number of side discharge openings or apertures corresponding to the auxiliary primary hot air pipes, each auxiliary pipe having its end communicating with a side opening, and the primary hot air pipe being left free to discharge hot air near one end.

In testimony whereof I hereunto afiix my signature.

JOHN B. MUSE.
