i as'will be fully hereinafter set forth.

For the purpose of illustrating my invention, I have shown in the accompan ing found in practice to give satisfactory and redrawings one form thereof which has con liable results, although it is to be understood that the various instrumentalities of'whieh my invention consists can be variously 81'? ranged and orgamzed and that my uventnm 'A'Bnot limited'to the precise arrangement and. organization of these mstrumentalities as herein shown. Y e 1 represents. sectional elevation of building provided with a system of drying ventilation embodying my invention. Fig. 2 represents a perspective View of one of the-drying frrrmes in detached position. Fi 3 represents in elevation, a portion'of a stac showing the manner in which I the drying roof 3, it be' second and third story of the build rising therefrom the walls 2 which support a understood that my system isadapted to e placed in any buildings now in use and that it is not essential to reconstruct the building in order to adapt the same for use with my invention.

4 designates a chamber preferabsy below the floor, provided with an inlet passage 38 which communicates with the atmosphere. The chamber 4 has located therein, -any suitable heating or coo system and for the pmpose of ii ustration, have shown as located in said chamber, a radiator through which hot water, steam or a suitable 0001111 mixture such as brine can be passed. After t e air has passed around the conduits 5, it passes through a passageway or canal 6, Which, in the present instance, communieates with a longitudinally extending canal 7 located between the double floors 8 and 9 of the second story, said passae 6 being controlled by means of a sui tab e gate or clo sure10.

-11 wai'dly from the canal 7 and communicating with. longitudinal canal 12 formed between the 'ublc floor of the third story. One of the s; edvalls 13 of the rooms 14 in the second story is deflected inwardly in order to form source of heat 16, from which extends a ipe 17, said 'ipe passing through the cans 11 and the ciinal 12, then down the canal 11 on the'opposite side of the building-and communlcating With' asimilar source of heat 'or cooling device 16 whereby the air which is admittedithmughpnepf the portals 410 designates passages ext-ending upa chamber 15 in which is located a when-the gate or: closure 19 therefor is open may be suitably heated before the same passes through the canals 11, 7 and ilto the different rooms, it being understood that when the source of heat or cooling device f ber passing-through the opening 21 controlled by the gate 22 and thence into the passage 23 which communicates with a canal or passage 24 preferably located on the side -or' the room opposite to the gate controlled inlet The canal or passage 24 extends 20 through the roof and communicates at 25 with the atmosphere, it being notedthat the passage 26 for the vitiated air communicates with the passage 27 leading to the chimney.

28 and that the passage 27 communicates by 2 means of passages 29 with the passages from the different rooms for the vitiated air such as 24. i 7 i 30 designates anopening through the floor of the upperstory, which communicates 30rwith the passages 11.

g 31 designates passages in the side walls of the rooms of the upper story communicating with the outlet passages 24 and 26 as: may

be clearly understood from Fig. 1.

, 32 designates a series of conduits which pass through the passages 7 11, 12 and through the openings 30 and 31 of the upper floor whereby the rooms on the upper floor may be used as drying or cooling rooms and whereby any desired temperature may be constantly maintained therein, it being un-v derstood thatwhere the pi es oass through the floors they may be insu fltfl in any suitable manner such as is well known in the art and the pipes may be provided with vanes or ribs 33 whereby a greater amount of heatwill be given ofl.'

34 designate the side members which form the drying frame 35, said members havim united thereto any suitable material 36 such which. the airmay readily pass, it being "understood thatthe material which isto be dr ed is spread out on the portion 36 of the d ing frame.

e d 'ng frames are supported 'on "a skeleton amework 37, so that theair may readily pass therebeneath, the manner in which the frames are piled up being clearly,

60 shown in Fig. 3, and in 1, I have shown a side "elevation viewed from a different direction so that the' passageways formed by the stacks of frames may be clearly seen, it

being up arent that these frames 35 may be .5 arrange in the drying room in any suitable 'as gauze, cloth or any material. through manner and that, if,desired, the entire room may be filled with such frames from the bottom to the top thereof.

The operating and controlling of The system iiill now be readily apparent. if the s stem is applied only for ventilatimi as s own in the second story-of the building seen in Fig. 1; the gate 20 is raised and the fresh and heated air is permitted to pass into the'room and the gate 22 is o ened so that the vitiated air will pass t ierefrom through the opening 21 into the atmosphere communicating passage 24, it being understood that the heated air rises to the top of the room and the air as'i't is cooled gradually S0 falls until it passes through the opening 21.

Since the systems 5 and 16 are adapted to convey either a heating or cooling medium,

it will be apparent that any desired temperature it in certain limits may be maintained within the different rooms. .When

it is desired to employ a. room for drying purposes, the air at a desired temperature will pass into the room near one end thereof and the vitiated air will pass therefrom through a controlled opening into an atmos phere communicating passage.

It has been found in practice and by careful experimentsthat articles such as macaroni, noodles and other food articles-may be dried in substantially half the usual time when my system of d ing is employed. Furthermore at least dou lo the uantity of material to be dried may be placeil in a room under my system; so that the amount of drying space whichjt is necessary to employ is reduced to a minimum. The quality of the product is of the hi hest, since the natural sweet taste of the wheat or other article is retained and the liability of a moldy or sour roduct absolutely prevented.

It as been found in .actual practice that there is produced by the employment of my system a saving of 60% of the space necessary in the dryin rooms, 60% of the time necessary to-dry t 1e product, 30% of coal or equivalent heating materialand 50% of the space .necesse'ry for the settin" h p and operatron-of the machines n'hici produce the articles which are to be dried.

t will be apparent that for heating purposes either the exhaust steam or steam direct from the boiler may be employed and that any desired type of cooling medium may be assed throu the pipes I or c earness of i ustration, I have pre-- ferred to show thefloors as be ng double or hollow, but it is to be understood that in. adapting buildingsnow in use for my invcntion, that it is simply essential to have suitable passages or canals for the air and it is to be understood that I do not desire to" limit myself to a hollow floor or rooms having 4 hollow walls.

It will now be apparent that 1 have devised ing and ventilating system which embodies the features of advantage enumerated as desirable in the statement of invention and the above description and while I have, in the .I present instance, shown and described the referred. embodimentthereof which has een found in practice to give very satisfactory and reliable results, it is to be understood that my invention is susceptible of modification in various'particulars Without dcparting from the spirit and scope thereof or sacrificing any of its advantages.

I wish to call special attention to the fact that the vitiatcd air passes through the canals 24 and 26, which are formed by the hollow walls of the. rooms extending preferably the full length thereof, and the outlet for the Vitiated air is pl'ti filzl'llly formed between the double walls on one side of the room and extends the whole length thereof and from the bottom to the top.

It has been found in practice that'whcn my system is einployed for drying articles such as noodles, the desired results are not obtained unless the hollow walls for the asscges of the. vitiated air to the atmosp ere are employed, but this is not essential H1 regard to the inlet passage for the fresh and partially heated air, since one or more inlets may be employed and advantageous results ill be obtained.

It is of course to be understood that any desired number of passages leading from a room to the hollow walls may be employed according to the size-of the room and the rapidity with which it is desired to have the air circulate. I wish to also call SP8\.iBll attention to the fact that both the inlet :and outlet. for the air are in roximity to the floors of the rooms, as will e apparent from the drawing. It is further to be noted that it is desirable sometimes summe when the air is vcry'hot' and dry to employ accumula' tors of any well known or desired tvpe for forcing cool andimoist air through the, conduits and into the dii'ierent rooms so that air of an desired temperature or moisture may be employed. The accumulators would preferably be connected with a manually ac-, tuated force pump connected with a supply of fresh water so that the fresh air entering the building can lie'saturated with moisture to a desired extent, and since any desired type of awumulator and force pump may be employed, l have deemed it unnecessary to show and describe the same.
