Specification of Letters Patent. Application filed August 26, 1908. Patented April c, 1909'. Qericl. No. $50,286. s The object of my invention is to provide adevice in which seed cotton in various states of cleanliness can be treated and then assed directly into the gins. [It is a well *nown fact that the less the cotton is handled to put it into condition [or the spinner, the bet ter, since in the various cleaning operations, the fiber is apt to got broken, thereby im-- pairing its usefulness. In carrying out my invention I rovide adevice which is designed to give eacii batch of cotton coming to the machine a treatment which is especially adapted for the particular batch being cleaned, and in which the treatment may be varied. My invention is illustrated in the acconn panying drawings, in Which- Figured shows an enlarged gentral vertical section through the cleaner. Fig. 2 is a view of the heaters. Fig. 3 is a transverse section along .the liner 3-3of Fig. 1, looking in the direction of the arrow, and Fig 4 is an rior side view of the machine. Referring now to Fig. 1, A denotes in general an upright box or casing. Leading into the top of this box is a suction pipe B, which communicates with a feed hopper, not shown. The suction pipe B terminates in a downwardly curved end C immediately above the uppermost heaters. 'l he heaters themselves consist of a series of arms D, mounted on a shaitEc'apable of rotation in the direction indicated by the arrow in Fig. 1. There are four sets of these heaters shown in Fig. 1, although it is obvious that a greater or less number could be used. The axes of the heaters are arranged in an inclined position relatively to each other and they extend through the l ox l l l tions. The screen extends from the partition F to the bottom G of the box. Projecting downwardly from the upper part of the box A are the partitions H an 1, and a screen J extends from the top of the box down to a door K, adjacent to the lowermost set of heaters. The space between the partitions H and 1 forms a curved chute, and at the top of this chute there is a hinged door L, pivoted at k and arranged to swing upwardly into the osition indicated b "the dotted lines, there 3y closing the pipe and providing an opening into the top of the chntej A similar door M is provided and is pivoted at m to swin upwardly into the position indicated by t e dotted lines and to serve as a deflector to turn the cotton into the chute, which is provided between the screen J and the inclined wall 0 of the casshown in l -ig. This provides a triangular air duct at the up or end of the casing coininunicating with tie air outlet X. In order to operate the doors M and K sirnuitaneously, l have provided the shifting iever P. This lever is pivoted at Q toa cross bar R, the latter being in turn pivoted to an upper laterally extending arm T of the doord /i, and to a let erally extending arm T of the door K. it in clined screens N and N extend from the top of the casing A to the sides as clearly Will be seen that in the position of the doors K and M in Fig. 1, a downward pull of, the lever will result in opening the door M and closing the door K. The pull rodUis provided for the purpose of opening the door L, and this is accomplished through the medium of the extension of the downwardly extending arm V attached to the latter door. The arranementoi the pulleys for driving the heaters is shown in Fig. 4. It will he seen that the belt W passes over the pulleys a and i), then underneath an idler c and over the pulleys d and c, thence to an idler f. This arrangement provides for driving all of the shafts E in the same direction. X indicates the air outlet. Y and Y are doors, and Z indicates the outlet openingfor the cleaned cotton. From the foregoing description of the va- Afrorn one side to the other, as shoyvn in fig. l rious'parts of the device, the operation will 3,beu1g ournaled in the side walls of the box. .be readily understood. In practice the cot Immediately underneath each set of heaters ton is carried through the I arrange a curved screen S, having a small hopper, and if the cotton i pi e B from the S l? clearance. ihese screens meyh'eseparate or mitted to pass through to the end of the pipe 55in one continuous screen having curved seeeland be projected downwardly upon the arms rty, it is per- I carried around rapidly and the dirt thereder and behind the b air being scattered 'to pass directly into the Horn is screened out through the screen S. In passing the screens N and N, anyloose dirt is drawn through the screens, while the cotton is deflected down the chute. The uppermost beater tosses about the cotton and delivers it to the next heater, which, in turn, subjects the cotton to a similar heating ac tion, and passes it on to the third, and thence to the fourth, from. which it is finallydelivered through the eXit opening Z into the gin. If, however, a batch of cottonis being treated which does not contain as much dirt, and therefore should not be subjected to the thorough beating which itwill receive by being passed through the entire series of heaters, it Y may be deflected downwardly through the chute formed by the partitions II and I, by pulling downwardly on the pull rod U and thereby raising the door L to its deflecting position as. shown by the dotted lines in l ig. 1. In this position the cotton would be deflected so as to he acted on by the last two heaters only. If, new, a batch should be encountered which it was desirable gin, the pull rod P would be operated, thereby 0 ening' the u per door M and closing the ower door thereby passing the cotton directly into the gin without subjecting it to the action of the heaters. It will'be observed that the air space uneaters is large, and the over such an area of screen, as indicated by the arrows, allows the heavy dirt, sand, trash and other matter to settle to the bottom of the cleaner instead of being carried out through the air outlet. The provision of the doors Y and Y allows free access to the interior of the device for cleaning purposes. 7 It will thus be seen that I have provided a device in which the cleaning operation can be varied to suit Wrrious hat .es of cotton by a similar arr.-ingement of deflecting doors and levers therefor and chutes to cooperate therewith. I claim- 1. Ina cotton cleaner, an air pipe, a cleaning chamber connnunicating there with, said cleaning chamber having downwardly extending partitions forming chutes, doors at the tops of said chutes arranged to swing upwardly into said pipe and to constitute deflecting members, an inclined series of heaters arranged underneath said chutes, a screen underneath said heaters, means for conveying cotton through said of the uppermost set of heaters, where it is I for opena'ir pipe to said heaters, and means into said ing said doors to deflect the cotton chutes.- 2. In a cotton cleaner, an air pipe provided with doors in its bottom, chutes communicating with said air pipe, an inclined. series of heaters, means for assing cotton through said air pipe and tirough the entire series of heaters, and means for deflecting the cotton. through a chute and thereby passing the latter through only a portion of the series of heaters. '3. In a cotton cleaner, an air pipe conveyer, a cleaning chamber communicating therewith and provided with a downwardly extending partition at one side thereof, said partition constituting with the adjacent exterior walla chute, a series of heaters arranged between said partition and the opposite wall, a door in said air conveyer communicatin with the top of said chute, a door at the bottom of said partition opening into said chute, and means for simultaneously moving said doors to cause the material conveyed by the pipe to pass through the heaters or through the chute according to the position of the doors. 4. In a cotton cleaner, a cleaning chamber, heaters arranged therein, a screen arranged underneath said heaters, an air pi e conveyer communicating with said 0 amber and arranged to deliver material to said heaters, a door in said air pipe for deflecting the conveyed material through a portion of the series of heaters, and other means for deflecting material through the entire series of heaters. 5. In a cotton cleaner, an air pipe convcyer, a cleaning chamber, a series of heaters arranged in said cleaning chamber, the first of said heaters being immediately beneath the mouth of said conveyor, a screen for separating the dirt, means in said air conveyer for deflecting material through certain of said heaters and other means in said conveyor for deflecting material through the entire series of heaters. 6 In a cotton cleaner, a cleaning chamber provided with heaters and screens, an air conveyor for delivering material to said heaters, and means for passing material from the conveyer at will through the entire series of heaters or through a portion of the series. , SAMUEL WILLIAMS.
