June 28, 1949. J. J. WALLACE SYSTEM FOR THE, PREGINNING OF COTTON Filed June 18, 1946 3 Sheets-Sheet 1 June 28, 1949. J; J, WALLACE 2,474,642

SYSTEM FOR THE 4PREGINNING OF COTTON Filed June 18, 1946 -3 Sheets-Sheet 3 scribed. When in broken line position, it blocks conduit 8 and shunts the cotton into conduit I2.

The conduit I2 at its lower end divides into two bran-ches 25 and 26, the former conducting the cotton through path B, and the latter by way of path C. A valve 21 at the mouth of conduit I2 controls the selective flow of cotton through one or the other of these branches.

Branch conduit 25 leads to the cleaning units I4 and I5, unit` I4 being a vacuum condenser in which vacuum is maintained by a suction pipe I6, communicating with a fan chamber I1 containing a suction fan (not shown), the latter discharging into a trench containing a trash conveyor 2 I.

The unit I5 is a multiple drum cleaner, also having a drying and conditioning function., since hot air is blown into it through conduits 22 and 23. The drum cleaner has an underlying dust and trash hopper 24, which disch-arge into the fan chamber I1, and eventually into the trench 20. The cotton is elevated in the drum cleaner and discharges from the upper end thereof into the hopper 9.

From the cleaning units I4 and I5, the cotton passes to the hopper 9, from which it is normally drawn into the supermultiple extractor I0, passing therefrom to the gin 6.

When the valve 21 is swung to a position blocking branch conduit 25 and opening branch conduit 26, the cotton is diverted so as to pass first through the multiple extractor 28 and cleaner 29, and then by way of conduit 30 to the condenser I4, and serially through the cleaning instrumentalities I4 and I5 to the hopper 9 and normally through the supermultiple extractor IIJ to the gin 6.

It is to be understood that the entire cleaning system, beginning with the conduit II which leaves the distributor, and including the serially connected cleaning apparatus units which constitute the alternative paths A, B and C, are individual to the gin 6 and duplicated for each gin in the battery of gins, and it is emphasized that since only a small stream of cotton suicient to supply a single gin is fed through the conduit I I and through the cleaning units in any one of the selected paths, the cotton will be cleaned more thoroughly than it is possible to clean a stream of cotton large enough to be later distributed to a plurality of gins.

For one reason or another, as for instance to clean the roll box, it is necessary from time to time to temporarily stop one of the gins of the battery, necessitating cutting oli the flow of cotton to that gin. The following arrangement permits this to be done without interrupting the operation of the cleaning system. Each of the hoppers 9 is connected to a common conveyor trough 3I, having a screw conveyor 32, which leads back to a storage bin 33. A gate valve 34 controls the outlet from each hopper. When in the broken line position shown in Figure 3, it directs the discharge of cotton from the hopper to the supermultiple extractor I0 and gin 6. When it is in the full line position shown, it blocks the passage to the supermultiple extractor and opens the hopper to the conveyor 32, so that the cotton destined for the interrupted gin is then discharged into the bin 33. This may be cotton from conduit 8, which has only passed through the preliminary cleaning and conditioning apparatus I and 3, or it may be cotton which has been processed in the cleaning apparatus constituting paths B and C. When the stopped ,Y giufs again put into operation, theilow of cot- 4 ton thereto i's resumed simply by turning the' gate valve 34 again to its broken line position.

At any desired time the cotton in the bin may be returned to the cleaning system by way of a conduit 35, which divides into branches 36 and 31, the former leading to the preliminary multiple extractor I, and the latter to the distributor. A gate valve 38 at the mouth of conduit 35 may be turned to direct the cotton into either of the branch conduits 36 and 31. Thus the cotton from the bin may be completely reprocessed, or alternatively, be made to by-pass the preliminary processing apparatus and go direct to the distributor 5, from which it may be selectively sent through any one of the paths A, B and C in the manner previously set forth,

The movement of cotton throughout the system from one apparatus unit to another is effected, aside from the mechanical conveyor herein disclosed, by a conventional air suction system which it has not been considered necessary to fully illustrate or describe.

It will be understood that the invention does not lie in the specific cleaning and conditioning instrumentalities per se, any or all of which may be old in the art, but it resides in their novel arrangement, and the manner in which they are connected, and in which the traverse of cotton therethrough is selectively controlled whereby it may be selectively subjected to various degrees of cleaning according to the condition of the seed cotton.

Referring to the flow sheet, the following apparatus therein designated may be exemplified by the apparatus disclosed in the following patents:

What I claim as my invention is:

1. A system for the pre-ginning processing of cotton comprising a battery of a plurality of gins, a distributor for distributing cotton to each of the gins of said battery, an extractor and drier common to said gins anterior to said distributor discharging into said distributor, and a series of processing instrumentalities individual to each gin, between said distributor and gin through which cotton passes to the gin, said series including an extractor adjacent said gin, an intermediate group including a vacuum condenser and drum cleaner, and a group at the head of said series including an extractor and cleaner, a conduit for each gin at spaced points in the length of said distributor for supplying cotton to the gins, said conduit having branches .communicating with said series respectively between said adjacent extractor and said intermediate group, between said intermediate group and head group, and anterior to said head group, and selectively operable means for determining the flow of cotton into any one of said branches whereby it ispassed to said gin through said adjacent extractor only, serially. through said intermediate group and said.
