United States Patent O 3,430,555 UNLOADING TABLE FOR BULK CURED TOBACCO Thurman R. De Bruhl, Rte. 1., Trenton, N.C. 28585 Filed Sept. 27, 1967, Ser. No. 671,052 US. Cl. 10034 Claims Int. Cl. B65b 13/18 ABSTRACT OF THE DISCLOSURE Apparatus used in the removing of bulk cured tobacco from a separable bulk tobacco rack which includes an automatic release for a portion of the rack and a holddown member for tobacco so that the other portion of the rack can be released. After the bulk tobacco has been removed from the rack, the tobacco leaves are secured together.

BACKGROUND OF THE INVENTION Field of the inventi0n.This invention relates generally to apparatus for processing and treating agricultural products and specifically to apparatus used with bulk tobacco after it has been cured.

Description of the prior art.--For many years tobacco was cured by gathering several leaves together into a hand, looping twine or string about the stems, placing a plurality of hands on a stick and curing the same in a barn. After the tobacco was cured it was removed from the stick and placed on a pallet or basket and sold. This process required much hand labor and in recent years bulk tobacco curers have come into widespread use in an effort to avoid the labor problem. In a bulk tobacco curer a relatively large mass of tobacco leaves are placed on one portion of a rack and thereafter a second portion of the rack is applied to the tobacco. This second portion has a series of tines 'which are forced through the mass to hold the leaves during the curing process. After the tobacco has been cured it has been removed from the tines by hand and placed on the pallets to be sold.

SUMMARY OF THE INVENTION Apparatus adapted to receive a rack of bulk cured tobacco and separate one portion of such rack from the other portion and the tobacco leaves. The apparatus then holds the leaves in position while the portion of the rack with the tines is withdrawn from the leaves. After the rack is entirely removed the portion of the apparatus holding the leaves is raised and the leaves are gathered into a bundle which is tied together by twine or string.

It is an object of the invention to provide a relatively simple unloading table for bulk cured tobacco which will expedite and simplify the removal of a bulk tobacco rack after the tobacco has been cured.

Another object of the invention is to provide an unloading table for bulk cured tobacco having means for separating a bulk tobacco rack and supplying means for holding the mass of cured tobacco leaves together.

BRIEF DESCRIPTION OF THE DRAWINGS elevation Patented Mar. 4, 1969 DESCRIPTION OF THE PREFERRED EMBODIMENT With continued reference to the drawings a conventional bulk tobacco rack 10 is provided having a lower portion 11 constructed of a hollow framework with a locking member 12 on each end. An upper portion 13 of the rack includes an elongated top member 14' connected to generally vertical end members 15 to provide a generally inverted U-shaped body. The top member 14 has a plurality of spikes or tines 16 connected thereto which have one end extending downwardly a distance greater than the length of the end members 15, so that the tines will pass entirely through the tobacco leaves and terminate within the hollow framework of the lower portion 11. Each of the end members 15 has a latch 17 adapted to engage the locking member 12 of the lower portion to maintain the rack in assembled relation. The structure thus far described is conventional in the prior art and forms no part of the present inventive concept.

After the tobacco has been cured the leaves of tobacco 18 must be removed from the rack 10 and in order to assist in such removal an unloading table 20 is provided having a fixed frame or base 21 with a leg 22 at each corner. If desired certain of the legs or all of the legs may 'have ground-engaging wheels 23 mounted thereon so that the table can be moved easily from place to place. The fixed frame 21 preferably has a pair of generally parallel side members 24 connected at opposite ends by end members 25 to form a generally rectangular frame. A pair of longitudinally extending tobacco leaf supporting members 26 are welded or otherwise attached to the end members 25 and extend substantially the full length of the frame in spaced relation to and generally parallel with the side members 24.

At one end, the frame 21 has one or more upright posts 27 to which a movable frame 28 is pivotally mounted by pins 29. The movable frame 28 includes a pair of spaced generally parallel side members 30 of a length longer than the fixed frame 21 and which extend outwardly beyond the upright posts 27. The side members 30 are connected at one end by an end member 31 and at the opposite end by a counterweight 32. At the end of the fixed frame 21 remote from the posts 27, an upright latch supporting member 33- is provided having a latch 34 mounted thereon in a position to engage the end member 31 when the movable frame 28 is in its lowermost position. The movable frame normally is in a generally upright position as illustrated in FIGS. 3, 4 and 6 but can be swung to a position generally parallel with the fixed frame 21 as illustrated in FIGS. 1, 2 and 5.

An upright shaft 35 is mounted on the counterweight 32 and is adapted to receive a ball of twine 36 held in position by a flat plate or washer 37 and a nut 38 carried by the shaft 35. The twine extends from the ball 36 through an opening 39 in the plate 37, through a guide 40 carried by the counterweight 32 and then to a clip 41 at the opposite end of the fixed frame 21. If desired a sharp razor-like cutter blade 42 can be welded or otherwise attached to the fixed frame 21 in any desired manner, as by welding, fasteners, or the like, and utilized for severing the twine.

At each end of the fixed frame 21, a post 43 is provided and these posts function as guides for the rack 10 when the rack is placed on the table 20. An upstanding lug 44 is mounted on each end of the fixed frame 21 adjacent to the posts 43 and adapted to engage the upper portion 13 of the rack to locate the rack in correct position. A latch release member 45 is fixed to each of the end members of the fixed frame 21 in a position to engage the latch 17 of the rack as the rack is lowered onto the table, as illustrated in FIGS. 7 and 8.

In the operation of the device, after a rack of bulk tobacco has been cured, the rack is removed from the barn and placed on the table with the upper portion 13 in engagement with the posts 43, after which the rack is lowered until the leaves of tobacco 18 rest upon the supporting members 26 of the fixed frame 21. Just before the leaves reach the supporting members 26, the latch release members 45 will engage the latches 17 of the rack and release the lower portion 11 so that such lower portion will fall by gravity to the ground below the table 20. When the rack has been separated, the movable frame 28 will be swung downwardly about the pins 29 until the end member 31 engages the latch 34 and locks the movable frame in lowered position, at which time the side members will be in direct engagement with the mass of tobacco leaves 18. With the leaves thus held by the table 20, the upper portion 13 of the rack 10 is removed from the leaves, as illustrated in FIG. 5, after which the rack can be refilled with leaves of tobacco to be cured or stored for future use. The latch 34 then is operated to release the movable frame 38 and such frame is returned to its initial upright position by the counterweight 32 and a length of twine, which at this point is located below the leaves of tobacco, can be cut on the blade 42 and the opposite ends brought upwardly around the mass of tobacco leaves and tied together to form a bundle which is then removed from the table. When the bundle has been removed, the end of the twine is pulled the length of the table and placed within the clip after which the process is repeated.

-It will be apparent that a relatively simple unloading 7 table for bulk cured tobacco has been provided which will automatically separate portions of a bulk tobacco rack and thereafter portions of the table can be moved into engagement with the leaves of tobacco so that the remaining portion of the rack can be removed easily and quickly.

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