To all whom it may concern c it known that I Josi-iUA C. Conan), a citizen of the United States, residing at which the screen c0acting With the crushing and segregating mechanism shall be adpistable toward or from said mechanism.

This par i ion. I comprises a crushing cylinder 18 and co- 1w ventioi further consists in a cotton acting concave 19 together with a plurality .l

cleaning machine ,as above mentioned in of heaters Qtland ace-acting screen The cylinder 18 is of heavy cast iron construetion and provided on its peripheral face with diagonally disposed ribs or lugs 22. The concave 19 comprises a yieldingly supported member 23 having a concave face adjacent the cylinder 18 to which is secured cast plates provided with ribs or lugs 2 1 similar to the lugs 22 and adapted to co-act therewith. -The concave 19 is supported by rods 25 extending through frame members 26, and springs 27 interposed between the members 23 and 26 hold the concave yieldingly in position. 28 indicates a nut on the rod 25 for limiting the inward movement of the concave and serving as means whereby the normal position of the'same with relation to the cylinder may be regulated. The heaters 20 comprise wooden cylinders 29 provided with a large number of radially projecting pins or spikes 30. The screen 21 extends from the lower edge of the concave 19 to the upper adjacent edge of the valve shell -6 and is shaped to conform to the crusher cylinder and the beaters throughout about half of the circumference of the latter. The heaters are preferably arranged one above the other as shown in Fi g. 1 and the screen therefore comprises a series of superimposed substantially semi-eylindrical por tions between the adjacent edges of which are arranged brace members 31. The screen 21 and brace members 31 are secured to substantially vertical members 32'which lie fiat against the sides of the box 1 and which are hingedly mounted at the bottom as at 33, by which construction the screen may be adjusted toward or from the heaters as desired. The members 32 are provided with slots 34: through which extend thumb screws 35 for securing the device in adjusted position, Extending over the crusher cylinder 18 for a short distance from the upper edge of the concave toward the inlet 3 is a short screen section 36. It will be noted that the sect-ion 36 forms a substantial continuation of the screen 21' and said screen 21 is arranged between the crushing and segregating mechanism and the air dust 5.

The bottom of the box beneath the screen 21 is inclined as at 37 and at the lower edge of the incline 37 is formed a channel 38 in which is arranged a screw conveyer 39. The

I bottom portion 37 is hinged as at 40 and constitutes a door whereby access may be had to the screen 21 foradjusting, repairing, or removing the same.

Hingedly mounted at the lower edge of the inner endof the duct 3 is a valve 41 which is preferably solid or imperforate, and to the upper edgeof the duct is secured a valve 42 which is formed of screening and which when in one position forms a continuation of the screen 21 and in another position a continuation of the screen 13. The valves 41 and 42 are operated by levers 43 and 44; and if preferred these levers may be connected by suitable means 45 whereby they may be operated simultaneously.

The shafts of the cylinder 18 and heaters 20 are provided with pulleys l6 and 17 respectively which are coupled by belting 18, 49 and 50 shown. The shaft of the cylinder 18 is also provided with a pulley 51 for the power belt not shown. 52 indicates the pulley for the belt for driving the rotary air valve 7.

The operation of the device is as follows: A partial vacuum is create in the box 1 through the duct 5 and the cotton to be cleaned is drawn thereby through the duct 3. If the cotton has been picked from the bolls the valves 41 and 42 are dropped into the position shown in full lines in Fig. 1, unless dirty and trashy, in which event the cotton will-pass through the chamber 14 to the valve 7 and thence through the port 8 to the gin or elsewhere as desired. As the cotton passes through the chamber 1 1 is drawn against the screen 13 and the dust and dirt is separated therefrom by being drawn through said screen. It should be noted that the screen 12 forms a continuation of the screen 13 thereby increasing the area of the cleaning surface.

Shouldthe cotton fed to the device be in the bolls, or dirty or trashy, the valves 41 and 42 are raised as indicated in dotted lines thereby causing the cotton to pass into the chamber 15 to be acted upon by the bell crushing and segregating mechanism. The valve 41 across which the'cotton asses, be ing imperforate, prevents any 0 y the dirt from dropping through the chamber 14 to the valve, and the valve. 452 forms a continuation of the screen 21. As the cotton passes between the cylinder 18 and-concave 19 the bolls are crushed and as it passes between the heaters 20 and the adjacent portions of the screen 21 it is segregated and the dust and dirt together with portions of the bolls are drawn through the screen to be carried away by the duct 5 or the conveyor 39.

This device may be used as an unloader or circulating machine as valves 7 will discharge in an air space as well as in the open.

- Having described my invention what I claim as new and desire to secure by Letters Patent: v

1. A device of the class described, comprising a vacuum box, a valved discharge at the lower end thereof, an inlet adjacent the upper end of the box, an air duct leading from the o posite side of said box from said inlet a su stantially vertical screen partition dividing said box into two chambers, a pair of valves, a connection between said valves for operating the same simultaneously to direct the cotton from said inlet into either of said chambers, each of said chambers communicating at its lower endwith said valved discharge, boll crushing and segregating mechanism in the chamber in direct communication with said air duct,

5. and a screen co-acting with said segregating mechanism and adjustably mounted between the same and said air ducts, substantially ,as described.

2. A device of 10 prising a vacuum box,

class described coma screen part tion die the viding said box into two chambers a valved discharge In communication with the lower end of each of ing into said box said chambers, an inlet 1ead-' above the upper end of 15 said partition, valves for directing the cot-- ton from said inlet bers as desired, an

into either of said chamair duct leading from one being imperforate and the other valve being foraminated and 1h one position formscreen between the segregating mechanism and the air duct, substantially asdescribed. In testimony whereof I have signed my mg a continuation of said screen partition and in another position a continuatlon of the name to this specification in the presence of two subscribing witnesses.
