A itomeys Patented Sept. 10, 1940 UNITED STATES COIWBINEDE'SEPARATOR AND DRIER FOR, THE TREATMENT OF COTTON I George T. Sims, Columbus, Miss. Application June 13, 1939, Serial No.- 278,984
This invention relates to a combined separator and drier, and has for the primary object the provision of a device of this character which may operate in conjunction with a conventional cot- 5 ton gin for separating foreign matter from cotton and for drying the cotton prior to reaching the gin, so that the cotton will be in a much better condition for ginning permitting the ginning operation to be carried out more efficiently l and quicker.
With these and other objects in view, the invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation illustrating a com- 0 bined drier and cleaner for the treatment of cotton and constructed in accordance with my invention.
Figure 2 is a fragmentary vertical sectional view illustrating the main casing of the device 935 in which the cotton is separated from foreign matter and dried before being discharged therefrom to a conventional gin.
Figure 3 is a fragmentary end elevation, partly in section, illustrating the means of picking the 30 cotton and separating foreign matter therefrom during the drying operation.
Figure 4 is a sectional view taken on the line 4-4 of Figure 2.

Figure 7 is a perspective view illustrating another type of bafiie used in the device.
40 Referring in detail to the drawings, the numeral 5 indicates an elongated vertically arranged casing having its upper end connected with a separator of a gin of a conventional construction (not shown). and includes a separator 45 6 having a neck 6, the free end of which terminates laterally of the casing 5 in a horizontal plane and in the form of a pipe 1' to receive by suction cotton from a wagon or like conveyance. The separator further includes a screen l3 for 5 intercepting the incoming cotton and causing the cotton to gravitate into the casing 5 while the suction air passes into a conduit 1 forming a part of the gin construction and which is provided with a vent 9 controlled by a suitable damper.
' 55 The suction fan is indicated by the character I2.
It is to be understood that the suction fan draws the cotton into the separator 6 where it passes by gravitation into the casing 5.
The cotton gravitating in the casing is intercepted by groupsofpivotally mounted baffles I4 and [5. The bafiies it of one group are arranged in superposed relation and at one side of the casing, while the baffles i5 are arranged in superposed relation at the opposite side of the casing from the baffles M and in staggered relation to m the latter, so that the cotton passing downwardly over said baiiies will be caused to gravitate in a zigzag path. The baffles I4. and on their pivoted ends have connected thereto arms i6 extending exteriorly of the casing 5 and connect- 15 ed by pivots to operating rods l l. The operating rods permit the inclination of the baiiles l4 and I5 to be varied. v
Picker rollers l8'of the toothed type are journaled' in the casing 5 and are arranged between the group of bames so that the cotton passing from the bailies M must come in contact with the picker rollers before reaching the baffles l5. If desired,'the baflle's It may be constructed of solid material while the baffles l5 may be constructed of foraminous material or perforated material. As the cotton passes from the baffles in its downward path of movement, the picker rollers tear the cotton apart and flufi up the cotton so that hot air in the casing will reach all particles of the cotton and thoroughly dry the cotton and the cotton being separated as described will loosen therefrom foreign matter.
The lower portion of the casing 5 has formed thereon, a receiving hopper l9 and an outlet pipe 20 for the treated cotton. The outlet pipe may lead to a conveyor (not shown) of the cotton gin. The mouth of the hopper i9 is traversed by a separator screen 2| disposed at an inclination, slanting toward the mouth of the outlet pipe 20 40 so that the cotton on leaving the lowermost-baffle will pass over the separator screen 2.! allowing the foreign matter to enter the hopper l9 and. the cleaned and treated cotton to pass from the casing 5 by way of the outlet pipe 20.
A heat discharge nozzle 22 is arranged in the casing 5 between the lowermost bafiie and the hopper l9 and the outlet pipe 20. The nozzle 22 is adapted to discharge hot air to the lower portion of the casing for movement upwardly through the cotton as the latter is torn apart by the picker rollers so as to remove from the cotton moisture and dampness and further aid in the separation of foreign matter from the cotton. The upward movement of the heated air is brought about through the suction received from the suction pipe 1, besides the natural tendency for heated air to rise.
The lower portion of the hopper l9 has a trap door 23 so that foreign matter accumulating within the hopper may be removed whenever desired.
The nozzle 22 is connected to a hot air pipe 24 leading to a heat chamber 24' having an air inlet 25 and a heating coil 26. The heating coil is arranged within the path of movement of the air received from the air inlet 25 on its travel to the pipe 24. The heat chamber 24 may be of any desired construction and its air inlet includes a conical-shaped portion 21 providing a seat for a conical-shaped valve 28. The conical-shaped valve is carried by a feed stem 29 journaled in a feed nut 30 carried by the frame 3| mounted on the air inlet. A crank handle 32 is connected with the feed stem whereby the valve element 20 may be adjusted relative to the feed for controlling the amount of air entering the heat chamber.
It is to be understood while I have described a specific construction of valve and operating means therefor for controlling the air another type of valve may be employed if desired. The coil 26 of the heat chamber is adapted to be connected in any well known manner to the steam type heat source (not shown).
The shafts of the picker rollers l8 extend exteriorly of the casing and have pulleys 33 secured thereto and trained over said pulleys are endless belts 34, one of which is crossed to bring about rotation of certain of the picker rollers in opposite directions to the rotation of the other picker rollers. One of the shafts has a drive pulley 35 secured thereto over which is trained a drive belt 36. Power is delivered to the drive belt from any suitable power source or from the cotton gin. The casing 5 between the baflies is provided with cleanout plates 31 which, if desired, may be in the form of windows to permit viewing of the interior of the casing during the treatment of the cotton therein. I
While I have shown and described the invenr: tion operating in conjunction with a particular type of separator of a gin it is to be understood that the invention can be successfully employed in conjunction with a separator of the rotatable type (not shown).
From the foregoing description taken in connection with the accompanying drawings it will be seen that the cotton entering the separator by the suction of the fan engages the screen l3 and falls into the casing 5 for gravitation therethrough. As the cotton gravitates from one bafie to another, the picker rollers act on the cotton to tear the same apart. During this operation heated air flows upwardly through the casing and removes from the cotton dampness, moisture or the like so that when the cotton leaves the casing by way of the outlet pipe 20 it is in the most highly efiicient condition for ginning purposes. The foreign matter leaving the cotton within the casing 5 passes therefrom into the receiving hopper l9.
It is believed that the foregoing description,
when taken in connection with the drawings, will fully set forth the construction and advantages of this invention to those skilled in the art to which such a device relates, so that further detailed description will not be required.
Having described the invention, I claim:
In a device of the character set forth comprising a vertically arranged casing adapted to receive cotton from a suction means, adjustable means in said casing to cause cotton passing therethrough by gravitation .to travel in a zigzag path, means acting on said cotton while moving in said path to tear the fibres of the cotton apart, a hot air discharge nozzle located in the lower portion of the casing, a trash hopper connected to the casing below said nozzle, a cotton outlet pipe connected to the lower end of the casing;
below said nozzle, a pipe connected to said nozzle, a heat chamber connected to said last-named pipe and having a heating coil therein and an air inlet neck provided with a flared portion to form a seat, and a valve element operating in conjunction with said seat for the control of air into said heat chamber.
