UNITED STATES, BATES OFEIQE-Fr MARCUS L. BRowN, or DECATUR, easies VENTILAT'QIN'G APPARATUS.

To all whom it may concern:

Be it known that I, MARCUS L. BROWN, a citizen of the United States of America, and resident of Decatur, in the county of Dekalb and State of Georgia, have invented certain new and useful Improvements in Ventilating Apparatus, of which the following is a specification.

This invention relates to ventilators and particularly to means for preventing the accumulation of moisture, gases, injurious vapors or heat in store houses and particularly for ventilating masses of cotton seed when stored in a bin or loft. 7

An object of this invention is to provide novel supporting means and ventilating means to accomplish the result stated, the same to be used in connection with buildings having floors with spaces thereunder or in connection with floors which cannot receive currents of air from below.

'A further object of this invention is to provide a ventilator of the character'indicated which may be made of difi'erentma- 'terials and which may be differently shaped according to the requirements in practice.

With the foregoing and other objectsi n View, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention indetail, -reference will be had 7 to the accompanying drawings forming part of this specification in which like characters denote corresponding parts in the several views, and in whi'ch Figure 1 illustrates a view in elevation, partly in section of a ventilating column embodying one form of the invention;

Application filed February 21, 191a s ns-1 noxzvaa's'a line -corresponding with the line -77 of ig- I Fig. 8 i'llustrates a sectional View on the line 8-8 ofFig. 5; and

Fig. 9 illustrates a sectional viewon the line 9-9 of Fig. 6.

In these drawings'15 "and1'6 denotes members of a T-shaped post which constitutes the frame of the column shown in Fig. l, the member 16 having beveledends as shown at "17 for engaging the wire netting 18 which, in the present embodiment of the in vention, is shown as tubular and tapering from the bottom flange 19'to the top flange 20', it being the purpose ofthe inventor to have the bottom flange 19'secured to a floor and the top flange 20 connected to a ceiling through which latter an opening may be formed to permit the circulation necessary to ventilate the binror room in which the column is stationed,.and it isalso, the purpose of the inventor to have an aperture in the floor, the said aperture being surrounded by the flange 19 :so that air may pass from the bottom to the top of theflcolumn, and aid in carrying away the heat which might be generated in a pile of cotton seed.

In Fig. 3, the sheathing21 of the column I is made of foraminous material, preferably sheet metal, and it is supported by a frame structure such as is shown in'Fig. :4, the dif ference between the sheathing in Figs. 3 and i bei-ngthat the sheathing QZinFig. 4 consists of. wire netting. I V y The frame structure of Figs. 3 and 4 consists'of aseries ofhoops orlrings 23 to which the sheathing may be secured by fastenings such as 24 and these hoops or rings 23 are connected together by vertically disposed strips such as 25, any number of which may be employed, and the vertically disposed strips are 'sec'ured to the'rings -or hoops by fastenings such as 24 which may pass through the sheathing as well as through the strips and hoops.

In the constructions noted, a bottom flange 26 and a top flange 27 may be employed having the same functions as the flanges 19 and 20 described in connection with the disclosure in Fig. 1.

In Fig. 4, however, provision is made for supplying air to the column in an eventthe ventilator is employed in buildings where the floor is concrete or where it is not supported clear of the ground. When such conditions are encountered, the flange 26 may be placed on the upper sid of a duct 28 which may be supported on the floor, and the end or ends of which may project through the wall of a building and communicate with the external atmosphere, so that the circulation of air can be insured through the said duct and through th column. In Fig. 4:, I have also shown the top flange as being connected to a ceiling 29 which ha an aperture 30 for the passage of air, it being understood that the building may be constructed in any approved way so long as there is provision for the escape of air at the top and for the admission of air at the bottom of the column.

In Fig. 5 a modified construction is illustrated, consisting of a frame 31 of the general structure of the frame illustrated in Fig. 4, the same being supplied with a sheathing of wire netting 32 and flange 33 which latter are also similar to the sheathing and flange shown in Fig. 4:, but in the construction shown in Fig. 5, the flange 33 is formed as a continuation or at least is carried by a metal jacket or covering 34 which telescopes on the netting 32 fitting the outside of the said netting and extending approximately half way down the post or ventilating column. It is encircled by clamps consisting of bands 35 with outturned ends forming ears 36 and 37 which are drawn together by a bolt 38 so as to exert pressure on the jacket to bind it against the netting 32. This jacket or covering serves two; purposes one to increase the draft or suction through the ventilator by confining the heated air while it is passing through the top and its second purpose is to permit the ventilating posts to be adjusted for different heights of lofts after which it can be clamped in position and so held. A ventilating column made in accordance with this last mentioned construction prevents dissipationof the air and confines it somewhat after th manner of a stove pipe and it results in increasing the draft and efficiency.

In Figs. 6 and 9, I have illustrated a still further modification in which the column comprises angular vertically disposed corner plates 39 held in spaced relation to one another by the bands 40 to form a frame, the said frame being embraced by a wire netting 41 so as to form a column which is square in plan. In this construction, the upper flange 42 and the lower flange 43 are of substantially the same construction as the flanges 19 and 20 except as to their configuration and their functions and purposes are the same.

By reason of the foregoing description and illustration it will be seen that the invention is susceptible of wide margin of modifications and the inventor does not, therefore, wish to be limited with respect to the exact details of construction since the invention resides in the broad idea as well as in the detail of construction appearing in the claims.

I claim 1. In a ventilating device, a frame, foraminous material encircling the frame and spaced therefrom at points in its circumference to form a column having vertical air passages, a flange at the upper end of the column, and a flange at the lower end of the column for anchoring the column.

2. In a ventilating device, a foraminous column, a sleeve constituting an extension of the said column, said sleeve comprising a tubular sheet metal member and clamping bands encircling the said member for causing the said member to frictionally engage,

the column whereby the said member is telescopically mounted on the column and secured at different positions of adjustment.

3. In a ventilating device, a foraminous column, a sleeve constituting an extension of the said column, said sleeve comprising a tubular sheet metal member and clamping bands encircling the said member for causing the said member to frictionally engage the column whereby the said member is telescopically mounted on the column and secured at different positions of ad ustment, and a flange carried by the said member adapted to be secured to a ceiling.
