Ser. No. 581,411 US. Cl. 34-233 Int. Cl. F26b 25/10; Etl4h 7/30 7 Claims ABSTRACT OF THE DISCLOSURE This is a continuation of application Ser. No. 386,181 filed July 30, 1964, and now abandoned.

The invention relates particularly to a base for a storage bin used for storing grains and other crops immediately after they are harvested and without the necessity of having to delay or give consideration to the excess moisture contained and is an improvement over the invention disclosed in Patent 2,818,009.

In the above indicated prior patent, the floor is supported on masonry blocks or the like which are bulky, did not allow full and free circulation of the air, were costly, and in order to produce adequate air distribution, it was necessary to use air directing bafies.

It is an object of the invention to simplify and improve the structure of the above identified patent and to provide a base for a storage bin in which instead of blocks being used to support the floor, prefabricated skeleton-type simple inexpensive lightweight floor units are provided of rugged open-work construction, a number of which can be used to support the floor of the storage bin, and which floor units will not interfere with the circulation of air, and which can be readily moved, stacked and stored.

Another object of the invention is to provide a storage bin with ventilating means including fans or blowers, located in opposed relation in order to produce maximum air circulation without ducts and baffles, means for modimying the temperature of the air, and which fans or blowers may be operated independently or simultaneously, and with a gravity-type shutter or structure for closing the opening to the fan when the latter is inoperative, the construction including L-shaped flashing attached to the wood sills and lying under the floor in a manner not to obstruct delivery of air to the grain directly above it without removing the flashing when the floor is removed to facilitate cleaning the inner chamber, the arrangement eliminating extra electric wiring and gas piping necessary to operate the fans and heating elements on the opposite sides of the bin, and minimizing labor, materials, and cost of installation.

Other objects and advantages of the invention will be apparent from the following description considered in conjunction with the accompanying drawing wherein:

FIG. 1 is a perspective of a storage bin with a base illustrating one application of the invention;

"ice

FIG. 2, an enlarged fragmentary detail perspective of the base with portions borken away and illustrating the open-work rugged floor supporting units or members, flashing for the margin of the floor, and opposed combination heater and blower units set apart by automatic shutters;

FIG. 3, a perspective of one of the floor supporting units in beam supporting position; and FI21G. 4, a fragmentary section on the line 4-4 of Briefly stated the storage bin base of the present invention is composed of an upright wall of posts or staves arranged in a circular manner and held together by tension hoops. At the top of this foundation structure is located a perforated floor supported by means of beams mounted on supporting units, a flashing being provided around the margin of such floor to provide a substantially tight joint or seal between the walls of the storage bin and the supporting air chamber forming base. Upon the base is mounted a conventional bin having a door and a roof. A pair of combination motor-driven heater and fan units are removably located in openings in said upright wall and on the interior, such openings are provided with gravity-operated louvers or shutters so that when one unit is not operating, the shutters will seal the opening to the unit and the exterior.

With continued reference to the drawing, an air-chamber forming base 10 is composed of concrete posts or staves arranged in circular or other form and bound together by hoops or bands 11, the ends of which extend through connectors .12 and have threaded ends 13 on which are secured nuts 14.

On this base 10 is mounted a bin forming wall 15 having attached thereto perforated brackets 16 through which J-clamps 17 are disposed having threaded ends 18 on which are received nuts 19. The J-clarnps engage the uppermost band 11 and thus bind the bin forming wall 15 to the base 10.

The bin may have a cover 20 with a ventilator 21 at the top center of the same and a perforated floor 22 supported by floor supports or joists 23 and longer supports or joists 24. The supports 23 are located around the margin and the supports 24 across mid-portion of the enclosure, an L-shaped flashing 25 being provided for sealing around the marginal edge of the floor.

In order to provide a support for the floor joists 23 and 24 in a manner to permit free substantially unobstructed circulation of air, a series of substantially Z- shaped open-work supports 26 are provided of upright and generally horizontally disposed members of heavy gauge wire or rod stock. This results in a lightweight structure without cracks or crevices for vermin or rodents and effects a substantial saving over a concrete block-type support. The supports 26 have generally rectangular upright terminals with corner posts 26 extending upwardly beyond the top of the same which serve to retain the supports or floor joists 24 thereon.

Each support 26 has a trio of portions 26a, 26b and 26c (FIG. 3) which form in an integral manner the uppermost first member 41 of a plurality of generally Z- shaped, horizontally disposed, vertically spaced first members, the remaining first members being indicated 42, 43, 44 and 46. The first members are joined, as by welding, by a plurality of substantially vertically disposed, horizontally spaced second members, all of which are identified by the numeral 47 (FIG. 3), and which second members are identical and comprise straight rods; with the four corner rods or posts 47a, 47b, 47c, and 47d having the extensions 26 at their upper ends. Due to the identical, integral and stationary shape of the supports 26, they may readily be stacked for storage and transportation purposes. Additionally, as best shown in FIG. 2, the supports 26 are placed in alignment within a plurality of parallel rows, and wherein within each row each support is placed in an identical position relative to the other supports 26 located in the same row.

Grain and the like placed in the storage bin 15 frequently contain excess moisture, a substantial portion of which must be removed in order to preserve the grain, and to accomplish this purpose, opposed combination motorized fans or blower arrangements 27 are provided which also may include heating or temperature modification means supplied through lines 28 and 29 with fuel or electrical energy for operating the fans or blowers and each unit having a frame 30 disposed in an opening 31 in the wall 10. Each frame 31 is provided with closure means for closing off the interior of the bin 15 to the fan 27 mounted therein, in the form of conventional louvers 32 which close by gravity and which remain closed until they are opened by the force of air produced by the fan. Thus air is introduced from each of the fanheating units 27 independently or in unison and when one is in operation the other will be closed but when both are in operation, since the projection of air is toward the center of the air chamber in the base, the air will be dispersed or distributed over the entire area. If desired, in addition to the base 33, an additional moisture barrier 34 may be employed for the air chamber 35.

It will be apparent from the foregoing that a base is provided for a storage bin, which base defines an air chamber containing simple sturdy open-mesh floor units which allow free circulation of the air as well as adequately support a floor and along the boundary of the floor is provided an L-shaped flashing which does not obstruct the delivery of air through the floor to the grain above, and which flashing need not be removed when the floor is removed to facilitate cleaning of the air chamber. Also, by using two motor-driven smaller fans in opposed relation, the cost is less than for a single larger fan, and the manner of use likewise will result in a saving while delivering air more satisfactorily to say nothing of a saving in the cost of wiring and the elimination of ducts with their inefiiciency. On the other hand, there is obtained maximum etficiency in air delivery without turbulence and invariably losses caused by the ducts and the increase of air velocity and loss of volume in the ducts.

It will be further apparent that by the use of the automatically operating shutters in the wall separating the interior of the base from the exteriorly mounted fans, the fans may be started and operated independently or together, the fans being connected directly to the housing of the air delivering fan and with such housing provided with suitable heating means.

It will be obvious to those skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof and therefore the invention is not limited by that which is illustrated in the drawing and described in the specification, but only as indicated in the accompanying claims.
