COTTON LINTER Filed April 6, 1936 2 SheeS-Shee'l'l 2 Patented Mar. 29, 1938 UNITED STATES PATENT GFFICE COTTON LINTER of Texas Application April 6, 1936, Serial No. 72,929

7 Claims.

'Ihis invention relates to new and useful improvements in cotton linters.

One object of the invention is to provide an improved mechanism for cotton linters, whereby the position of the linter brush and the back wind board, or stripper, may be positively controlled. An important object of the invention is to provide an improved mechanism for linters which is adapted to be connected with thelinter brush and with the wind board of the linter, whereby said brush and board may be simultaneously adjusted with relation to the linter saws, or individually adjusted with relation to each other.

Another object of the invention is to provide an improved mechanism for linters which is manually operable from the exterior of the linter, whereby the linter brush and back wind board of the linter may be moved into various adjusted positions without the necessity of gainlng access to the interior of the linter, whereby the adjustments may be made more readily during operation, and with no danger to the operator.

Still another object of the invention is to pro--V vide an improved mounting for the brush and back wind board of a linter, which is so constructed that a very fine adjustment of the brush with relation to the linter saws and a fine ad justment of the parts with relation to each other may be easily accomplished.

A further object of the invention is to provide an improved cotton linter having a windboard which is so constructed that it may be adjusted in a horizontal plane with relation to the linter brush, whereby an increased stripping action is had.

A construction designed to carry out the invention will be hereinafter described, together with the other features of the invention.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein:

Figure l is an enlarged side elevation of a portion of a cotton linter, having an adjusting mechanism, constructed in accordance with the invention applied to the brush and wind board thereof,

Figure 2 is a View, similar to Figure 1, showing the shaft bearing in cross-section,

Figure 3 is a transverse, vertical View taken through the linter brush Aandwind board,

Figure 4 is a horizontal, cross-sectional View taken on the line 44 of Figure l, and

Figure 5 is a partial, isometric view, showing one end of the wind board and its connection with the adjusting screw.

In the drawings, the numeral I0 designates a portion of a linter frame which may be of any 5 desired construction. The entire linter has not been shown because it is believed that the inventio-n will be readily understood without such showing. The usual linter saws II and brush I2 which is located behind said saws, are mountl0 ed transversely within the frame. As is clearly shown in Figure 2, the periphery of the brush revolves in close proximity to the saws I I, whereby said saws are kept clean. It is noted that for eiicient operation, the proper distance or space l5 between the saws and brush must be maintained. Since the saws Wear, and for various other reasons, the brush must be constantly adjusted.

To provide for a `quick and easy adjustment of the brush I2 with relation to the saws, said brush is .carried by a transverse shaft I3 which has its outer ends extending through the walls of the linter frame I0. These outer extended ends of the shaft I3 are journaled in bearing boxes I4 which rest on outwardly directed flanges I0 onopposite sides of the linter frame I0. Each bearing box is held in position on the ilange by stud bolts I5 which pass through slots I6 in saidiiange. The bolts are threaded in the base III of the box (Figure 1) and receive nuts I1 on their lower ends. It is obvious that when the nuts are loosened on the bolts the bearing boxes I4 may be moved horizontally along the flanges I Il. This horizontal movement of the boxes will move the brush shaft' I3 and brush I2 accordingly, whereby an adjustment of the brush with relation to the saws II may be accomplished.

For readily sliding each bearing box I4 to make the desired adjustment, a horizontally extending bar I8 is provided. The inner end of this bar lies contiguous to the underside of the flange I0 and is provided with an opening I9 through which the rearmost bolt I5 extends. It will be seen that as the bar is moved, with the nuts I'I loosened, the bearing box I4 is slid on the flange IU.

The outer end of the bar I8 is formed with a threaded shank or rod 20,' which is preferably made integral therewith. This rod extends rear- 5 wardly of the linter frame and passes through an opening 2| formed in the outwardly extend-V ing vertical flange 2| of the linter frame. Lock nuts 22 are threaded on the rod on each side of 4the ilange, and when said nuts engage the 55 flange, the rod 20 and bar I8 are locked in an immovable position, which in turn, holds the box I4, brush shaft I3 and brush I2 in an immovable position. To move said shaft, it is only necessary to change the position of the nuts 22 on the rod 20, whereby said rod and bar I8 may be moved. It is noted that after the nuts 22 have engaged the ange 2I, the bar I8, brush shaft and brush are held immovable. To further clamp the bearing boxes to hold the shaft and brush in an adjusted position, the nuts I1 are tightened on the stud bolts.

From the above, it will be seen that a simple and positive adjustment of the linter brush is provided. Also the brush may be moved any desired distance and, therefore, a ne adjustment of the brush with relation to the saw is had. This fine adjustment makes for increased efficiency of the linter.

In the rear portion of the linter behind the brush II, a suitable wind board, or stripper 25 is provided. This wind board may be of any desired construction but it is preferably box-like, being formed of a pair of angular members 26 and 21' which are secured together in any suitable manner. The members are preferably formed of sheet metal and a longitudinal vertical ange 21 is formed along the top of the wind board, while a longitudinal substantially horizontal flange 26' is formed along the lower edge of the same.

The bottom of the wind board is inclined, as is clearly shown in Figuresv 3 and 5, and a transverse sheet 28 is disposed parallel to this bottom, being spaced therefrom by a suitable filler 28'. This sheet extends the entire length of the board and is fastened to the board by rivets 29. A flexible transverse supporting member 30, has its rear end secured to the rear of the linter frame and extends forwardlyr therefrom and between the bottom of the board and the sheet 28. The member is of the same length as the board and has its forward end disposed at the same inclination as the inclination of the bottom of the board, whereby this inclined end readily fits in the space between the bottom and the sheet 28. The forward end of the member terminates short of the forward end of the board (Figure 3). With this arrangement, it is obvious that the entire board 25 is slidably mounted on the member and may be moved with relation thereto. The windboard thus constructed is cheap in manufacture, and also presents a thin edge adjacent the brush.

To support the windboard within the linter and also to guide said board in a horizontal movement on the supporting member, a plurality of blocks 32 are fastened on the top of the board adjacent the vertical ange 21. One of these blocks is mounted at each end of the board, while any desired number may be mounted at intervals therebetween.

Each block is formed with a horizontal opening 33 which extends completely therethrough. A guide bolt 34 extends from the rear of the linter frame IU and passes through the ange 21 and opening 33, and has its other end passing through an angle bar 35 of the frame Ill. A nut 36 is screwed onto the end of each bolt 34. Thus, it will be seen` that as the windboard 25 is moved, the bolts 34 guide the board in a horizontal direction.` The supporting member 3l0 is suiciently iiexible so that as the board is moved, the member flexes to permit the board to travel in a horizontal plane. It is noted that horizontal movement of said wind board changes its position with relation to the linter brush I2, whereby a very fine adjustment may be made.

For moving the wind board along its supporting members, an adjusting arm 3'! (Figure 5) is mounted on each end of the wind board exteriorly of the linter. Each arm is journaled on the outer end of a bolt 38, which bolt passes through a horizontal slot 39 (Figure 1) in the side wall of the linter. The inner end of each bolt is screwed into a threaded opening 40 in the end block 32. The lower end of the arm carries a collar 4I, preferably made integral therewith, and this collar is slidable on the threaded shank or rod 20. A pair of nuts 42 one on each side of the collar are threaded on the rod 20 to hold the collar in various positions thereon.

From the above, it will be seen that by tightening the nuts 42 against the collar 4I and then moving said rod, both the linter brush I2 and wind board 25 may be moved simultaneously. In such case, the position of the board with relation to the brush does not change. If it is desired to adjust only the brush, the nuts 42 are moved away from the collar 4I and the rod 20 moved through the collar, whereby the wind board remains stationary while the brush is moved. Similarly, if it is` desired to move the wind board alone, the rod 2i) remains in its locked position while the nuts 42 are moved away from the collar 4I on the rodi` and the collar 4I is slid therealong to move the wind board, after which the nuts are again tightened against the collar 4I. Therefore, the mechanism permits the brush and wind board to be moved either simultaneously or separately from each other. All adjustments are made exteriorly of the linter, thereby obviating the necessity of gaining access to the interior. Minor adjustments may be made while the'linter is in operation, whereby it is not necessary to halt the operation of the linter, which results in a great saving of time as well as minimizing the possibility of injury to the operator.
