COTTON-CLEANER.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed March 10, 1908. Serial No. 420,160.

To all whom it may concern:

Be it known that I, ALBER'r LEROY TREESE, a citizen of the United States, and a resident of Jennings, in the county of Pawnee and. State of Oklahoma, have invented a new and Improved Cotton-Cleaner, of which the following is a full, clear, and exactdescription.

This invention relates to cotton cleaners, and the object of the invention is to produce a device which will operate to clean raw cotton before ginning.

More specifically, the invention relates to devices for his urpose which employ pneumatic means or. advancing the cotton through the machine in treating the same, and the invention concerns itself especially with providing means for ejecting the treated cotton from the device; the invention further provides means for treatin the cotton with the bolt to remove the boil and dirt, and is also adapted for treating the cotton without the boll when it is simply necessary to clean the cotton.

The invention consists in the construction and combination of parts to be more fully,

described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specifiar characters of reference indicate corresponding parts in all the ngures.

Figure 1 is a vertical longitudinal section through the device; Fig. 2 is a vertical cross section on the line 2-9 of Fig. 1; Fig. 3 is a cross section on the line 33 of F 1 near the middle of the device; Fig. 4 is a vertical ection taken near the discharge end, on the lino 41 of Fig. 1; and Fig. 5 is a vertical ct-tion through the forward portion of the device, and illustrating the same when adapted for siu'iply cleaning the cotton without the boll.

Referring more particularly to the parts, rcpresents the case of the device, which is adapted to be formed of sheet metal or similar material, in the form of a'barrel or cylinder. The under side of this cylinder is formed with a longitudinally disposed channel 2 into which the refuse from the cotton passes. This channel is inclined so that it constitutes a chute, which delivers to a spout 3 on the under side of the case at the discharge end thereof.

Rotatablv mounted in the barrel 1 there is provided a horizontal shaft 4, which is adapted to be driven by a belt pulley 5. Within the barrel or case 1 there is provided a cylindrical screen 6 which is coaxial with the shaft 4, which extends from the forward wall or head 7 of the device to a point. near the right-hand wall 8, as indicated. The parts beyond the end of the screen and near the right-hand wall 8 constitute a separator 9. At this point upon the shaft 4 there is rigidly mounted a fan 10 having radial blades 11, four in number, as shown in Fig. 4. The space in which this fan revolves is directly over the delivery spout 3 for the refuse, but is separated from the same by an auxiliary screen 12, as illustrated in Figs. 1 and 4. The space in which the fan 10 rotates is out off from the screen 6 by a semi-circularheador diaphragm 13 having a vertical edge 14 disposed on the vertical diameter passing through the shaft 4, as indicated most clearly in Fig. 4. This diaphragm or head is disposed on the lefthand'side of the separator, and this side of the separator is provided with an inclined delivery spout 15 which projects toward the left as shown. The vanes or blades of the fan 10 are disposed radially as shown, and the diaphragm 13 fits closely against the inner. ed es of these vanes, as indicated in Fig. 1. r s shown also in Fig. 1, the channel or chute 2 communicates directly with the delivery spout- 3, and it also communicates therewith through the interior of the separator 9 and through the screen 12. At the junction of the channel and the spout 3 I provide. a horizontal baffle plate 16, the purppse of which will appear more fully hereina ter.

011 the upper side of the case 1 and at the end thereof remote from the separator 9, there is provided a receiving hopper or receiver 17, the lower edge whereof projects into the interior of the case so as to lie near the wall of the screen 6. One of the longitudinal edges of this hopper is provided with a bar or knife 18, the lowerv edge of which lies adjacent to the wall of the screen. The screen at this point is providedwith an opening so as to permitcotton to be fed into the hopper 17 and pass into the interior of the screen, as will be readily understood.

On the shaft 4 just, under the hopper 17 there is pro ided a rigid fan 20 which is quite close to the lower edge of the knife l8.-

Between the separator U and the fan 20 the shaft 4 is provided with a plurality of radially projecting arms or heaters 25.

The operation of the device will now be described: The spout 3 for the refuse is connected with a suction fan in the well-' liIlQWii manner so that a draft is produced into the device through the hopper 17. In the position of the fan 20 illustrated in Fig.

7 1, the device is adapted for treating cotton with the'boll. It will be observed that in this view the fan 20 isdisp'osed at the right of the hopper, so that. the path of the righthand edges of the blades lies near the righthand wall of the hopper. W hen the cotton with the boll is fed into the hopper 17, the revolving blades of the fan strike the bolls, break them up and separate them from the cotton. The inclination of the blades 23 then operates to produce a draft toward the separator and advances the cotton along the interior of the screen toward the separator,

and the cotton then comes into the path of the heaters 25. In this way the broken bolls and pieces of dirt become removed from the cotton and pass through the screen into the chute 2, where they find their way into the refuse delivery spout 3. The current of air strikingrthe battle plate 16 is divided, so that a portion of it will pass into the separator. In this way the movement of the cotton from the screen into the separator is facilitated. In this connection it should be understood that a draft or current of air is generated downwardly through the screen 12 from the separator into the spout 3. As

the fan 10 rotates in the direction of the arrow shown in Fig. 4, it will eject the cot ton from the separator at the spout 15; In this connection, attention is called to the diaphragm 13, which together with the -opposite wall '8, forms a trap to cut oil the spout 1.3 from the suction draft. The mannor in which this trao is formed is illustrated in Fig. 4. It will be seen from an inspection of this figure that the blades of the fan are closed in between the head 8 and the diaphragm 13 so as to prevent a backward flow of air through the spout 15 toward the spout 3.

When the device is to be used simply for cleaning cotton which is free from bolls, the fan 20 15 attached in the adjusted position shown in Fig. 5; that is, it is near the outer side of the receiver or hopper 17. When in this position, a space is left at the right of the fan through which thecotton can pass into the screen Without being beaten against the knife l8 by the blades of the fan. The "fan in this case simplyproduces'a current of air through the screen, but does not operate as a heater or breaker. It is, of course, essential that the width of the blades 23 of the fan, measured longitudinally of theshaft, should not be as great as the width of the hopper 17, so that the opening illustrated in Fig. 5 at the right of the fan, may be made.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
