GRAIN VENTILATOR.
Application filed June s, 1927. Serial No. 196,332. 1
This invention relates to agrain'ventilator and has for its primary object the construc tion of a ventilator designed to be positioned in a grain bin or corn crib to support-the grain contacting therewith while subjecting the grain to the beneficial effects of circulating air.
An object of the invention is the provision of a ventilator with a plurality of individually arranged deflectors, partially covering ventilating openings so as to permit the proper circulation of the air currents but will positively hold the grain against passing into the openings.
Another'object of the invention is the construction of a ventilator with a plurality of sections arranged in superimposed relation and rigidly connected together so as to facilitate erecting of the ventilator and permit the same to be installed in bins or cribs of different capacities.
Besides the above, my invention is distinguished in the novel manner of interconnecting the various sections and reinforcing the same in lateral direction so that the ventilator is fully capable of withstanding the usual strains to which a device of this character is subject when in use.
A. feature of the invention is the design and construction of the deflector so that the grain will be supported in the proper spaced relation with the opening to allow the proper passage of the air current through the opening.
With these and other objects in View the invention will be better understood from the following detailed description. taken in connection with the accompanying drawings, wherein:
Figure 1 is a side elevation of the ventilator,
Figure 2 is a vertical sectional view throughone of the sections,
Figure 3 is a vertical sectional view illustrating the hood associated with the tubular casing,
- Figure 4 is a side elevation of the top portion of the ventilator,
Figure 5 is a top plan,
Figure 6 is a cross sectional view through one of the sections.
Again referring to the drawings, illustrating one of the many constructions of my invention, the numeral 1 designates a plurality of sections arranged in superimposed relation and interconnected so as to facilitate the erecting of the ventilator and permit the same to be installed in bins or cribs of difierent capacities. As each section is of identical construction, the following description relating to one of the sections will be applicable tothe remaining sections.-
Each section consists of a tubular casing 2 provided with a plurality of sets of vertically alining openings 3 for allowing air currents to pass from the air shaft 4 in the casing through the openings 3 to be properly dis-.
tributed through the grain. For the purpose of preventing the grain from passing through the openings and into the air shaft and further to prevent the openings from being closed, or obstructed, I have illustrated a novel constructiorn of baffle 5 preferably formed from metal to have an attaching flange 6 and a plurality of inclined walls 7 inclining downwardly and laterally from its associated opening, so that the lower edge portion 8 is disposed below the opening but in spaced relation therewith so as to provide an air outlet 9.
Each end of the sections or tubular casings has attached thereto by means of a flange 10 an attaching collar 11, and when the sections are arranged in superimposed relation as shown in Figure 1, the collars of associated sections are arranged in abutting relation so as to be rigidly attached by means of the bolt 12. Thus it will be appreciated that the ventilator may be of any height desired depending upon the number of sections utilized in the construction of the ventilator.
For the purpose of materially reinforcing the ventilator against lateral strains and to materially increase the rigidity of the ventilator as a whole, I have illustrated a plurality of brace rods 13 connected to the bolts 12 and extending to any suitable support such as the rafters or side walls of the crib, in which the ventilator is installed. To complete the invention, I arrange a conical hood 14 in spaced relation with the open end of the uppermost section so as to provide a ventilating passageway 15 and to fully protect this passageway from the grain it will be noted that the annular edge portion 16 of the hood is laterally displaced from the associated open end of the section as clearly shown in Figure 3 of the drawings. For the purpose of rigidly holding the hood in the position just described, I provide a plurality of brackets 17 upstanding from the collar and riveted to the hood as illustrated at 18.
In the installation of the ventilator an opening 19 is cut in the flooring 20 so that outside air currents may pass through the opening 19 and travel through the air shaft provided by the various sections which air currents in their passage through the air shaft are properly distributed through the openings 3 into contact with the grain surrounding the ventilator. In concluding, I wish to call particular attention to the fact that the formation and connection of the various parts are such that they may be economically manufactured from sheet metal by a stamping operation in the case of the deflectors and hood and by a rolling process with relation to the cylindrical casing forming the sections. It is of course,to be understood, that various other types and designs of deflectors may be utilized to partially cover the ventilating openings and the various sec tions may be connected in various other manners than illustrated and connected in other relations and further the ventilator may be equipped with a hood attachment as illustrated or completely closed, depending upon what is the most advisable in practice, and
therefore, I do not desire to be limited in protection in any manner except as set forth in the following claim.
It is of course, to beunderstood that the ventilator may be used with a forced draft utilizing an electric fan or other suitable apparatus for forcing air throughthe casing and to increase the effective action the top of the ventilator may be closed.
l/Vhat I claim is:
A grain ventilator comprising an upright ventilating stack consisting of a plurality 1 of sections disposed one above another in alinement and in endwise contact, flanges upon the meeting ends of the sections having registering openings, bolts secured through said openings and connecting the sections of the stack in a vertical series, the Walls of the sections having ventilating openings, baifles upon the sections extending opposite said openings to prevent the passage of grain through the openings, and brace rods secured at their inner ends by certain of said bolts and extending radially from the stack.
In testimony whereof I affix my signature.
