TOBACCO-CURING BARN.

Application filed November 11, 1925. Serial No. 68,399.

This invention relates to a tobacco curing barn and aims to provide a novel construction of heating fiues whereby an oil or gas burning furnace may be employed for supplying the heat to the barn, thereby reducing the size of the furnace to the minimum and consequently reducing the cost of constructing a curing barn.

Another important object of the i1tvention is to provide means for utilizing the smoke and products of combustion for heating purposes prior to its passage from the barn.

A still further object of the invention is the provision of flues supported in such-a way as to induce circulation of the products of combustion and prevent choking of the dues.

With the foregoing and other objects in viewwhich will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is a plan view of a tobacco curing barn, the roof thereof being removed illustrating the fines. I

Figure 2 is a sectional view taken on line 22 of Figure 1.

Figure 3 is a plan view illustrating the usual type of furnace equipped with heating flues constructed in accordance with the invention.

Figure 4 is a sectional view taken on line H of Figure 3.

Referring to the drawings in detail, the barn is indicated generally by the reference character 5'and which is of the usual an well known construction.

The reference character 6 indicates the furnace which in this particular form of the invention is of the oil. burning type, and as shown, extends only a short distance within the barn proper.

Heat from the furnace 6 passes from the furnace at a point adjacent to its inner end and enters the fines 7 which are in communication with the inner end of the furnace by means of elbows 8. Flues 9 and 10 which are arranged on opposite sides of the lines 7 are connected by the fines 11 and elbows 12,the lines 7 being also in communication with the fiues 10, through the flues 13 and elbows l4.

Communicating with the fiues 9 are the lateral flues 15 which communicate with the fines 9 through the fiues 16, the flues 15 being also in communication with the outlet pipe 17, through the fiues 18 and 19 respectively. The flues 18 and 19 extend along the front wall of the barn as clearly shown by Figure 1. The pipe 17 dis charges the products of combustion into the smoke stack 20 which is positioned directly over the furnace 6 and exteriorly of the barn.

As shown by Figure 2 of the drawings, the flues 7 are inclined upwardly towards the rear wall of the barn, and the fiues 9, are inclined above the fines 10 in a direction towards-the rear end of the barn, while the fines 15 that communicate with the flues 9 are inclined towards the forward end of the barn thereby inducing a draft and insure against the products of combustion choking the fines. v

Associated with the furnace is an oil feed tank 21 that communicates with. the

interior of the furnace, through pipes 22 and 23, the latter pipes being provided with suitable nozzles to direct oil to the interior of the furnace where it 'mingles with air under pressure supplied to the furnace by the tank 24 and pipe 25.

From the foregoing it will be seen that due to this construction, the products of combustion will be circulated through the various fines of the heating system of the barn to the end that no portion of the heat from the products of combustion will be wasted, and the barn will be thoroughly heated with the minimum amount of heat and fuel consumed.

As shown by Figures 3 and 4, the furnace which is indicated at 25 is of the usual solid fuel burning type and extends into the barn, its rear end terminating in proximity to the rear wall of the barn. Flues 26 and 27 communicate with the inner end of the furnace 25 and extend towards the front wall of the barn from where they pass laterally and communicate with the fines 27 which extend towards the rear end of the barn and laterally communicating with the fines 28 that extend forwardly and inwardly at 29, the inwardly extended porof providing an oil burning furnace which incurs additional expense to persons having curing barns provided with furnaces of the solid fuel burning type.

We claim a In a tobacco curing barn, a furnace l1aving its inner end extending into the barn, .tlues connected With the furnace and communicating with the interior thereof, said flues having their forward ends disposed adjacent to the front wall of the barn, said fiues extending rearwardly to points adjaeent to the rear Wall of the barn, fiues communicating with the first mentioned fiues and extending towards the front Wall of the barn from Where they extend rearwardly towards the rear wall of the barn, flues communicating with the last mentioned fines and arranged adjacent, to the side Walls of the barn, and fines extending in parallel relation with the front wall of the barn and communicating with the last mentioned fines for exhausting products of combustion from the barn.

In testimony that we claipi the foregoing as our own, we have hereto aflixed our sig natures.
