WARREN A. PATTERSON, OF ST. LOUIS, MISSOURI, ASSIGNOR TO THE COTTON HAR- VESTER COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF SOUTH DAKOTA.

COTTON-SEPARATOR.

To all whom "it may concern.

Be it known that I, WARREN A. PATTER- SON, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Cotton-Separators, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in cotton separators, the object of my invention being to generally improve the construction of the machine shown and described in my application for Letters-Patent filed August 22, 1908, serially numbered 449,863.

For the above purposes my invention con sists in certain novel features of construction and arrangement of parts as will be hereinafter more fully described, pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure 1 is an elevation of the complete apparatus; Fig. 2 is a plan of the complete apparatus; Fig. 3 is an enlarged detail elevation, partly in section, illustrating the construction of the. cylinder employed in my machine; Fig. 4 is a front end elevation of the machine showing the means for adjusting the incline of the machine frame and parts carried'thereby; Fig. 5 is an enlarged detail sectional elevation illustrating the means whereby the saws and the brush are rotated; and, Fig. 6 is an enlarged detail sectional elevation showing the relative positions of the cylinder, the saws and the brush.

Referring by numerals to the accompanying drawings: 1 designates the frame of the machine. 2 designates a hinge member carried by the lower end of the frame. 3 designates the shaft inserted through the hinge members 2. 4 designates bearings for the shaft 3 and 5 designates standards for the bearings 4. At the opposite end of the machine frame and located on the cross tie of the machine frame 1, I position a plate 6 which is engaged by the end of the jack 7, which jack is supported in the internally threaded socket 8 supported in the cross tie 9, which cross tie is supported by the standards 10.

To prevent lateral movement of the frame 1, I have provided guides 11 which are se- Specification of Letters Patent.

Application filed. August 27, 1909.

Serial No. 514,853.

cured to the frame 1, each of which engages the standards 10.

Cross ties 12 are supported upon the upper faces of the frame 1 and bearings 13 are positioned thereon, and, to provide for an adjustment of the separator relative to the saw blades, I have provided wedge-shaped blocks 14 which are positioned between the bearings and the cross ties.

Rotatably mounted in the bearings 13 .is a shaft 15 and carried by the lower end of the shaft 15 is a pulley 16, and, embracing said pulley is a belt 17. Carried by the frame 1 and secured to its under side are cross ties 18. Carried by each cross tie 18 is a bearing 19 and rotatably mounted in the bearings 19 is a shaft 20. Embracing the shaft 20, immediately below the pulley 16 on the shaft 15, is a pulley 21 which is embraced by the belt 17. Carried by the lower end of the shaft 20 is a beveled gear wheel 22.

Hangers 23 are secured to the frame 1 and to the lowermost cross tie 18, and, carried by the hangers are the bearings 24. Rotatably mounted in the bearings 24 is a shaft 25 and carried by the shaft 25, in mesh with the beveled gear wheel 22, is a beveled gear wheel 26. To the opposite end of the shaft 25 is secured a pulley 27 which pulley is embraced by a belt 28 connecting with any suitable source of power (not shown).

A cylinder 29 is carried by the shaft 15, which cylinder is made up of a series of sections 30, each of which sections are made up of a series of integral rings 31 uniformly spaced apart and of uniform thicknesses. Each of the sections is provided with internally projecting ribs 32, the forward faces 33 of which ribs are substantially on a radial line from the center of the cylinder and the rearmost face 34 of each rib is curved. Each of the ribs is provided with an opening 35 extending throughout its length.

To position the sections of rings together I have provided the end plates 36, each of which plates is provided with a bearing 37 embracing the shaft 15 and secured thereto.

A number of stay-rods 38 are carried by the plates 36 and extend through each rib of each section of rings 31, the ends of the stayrods being threaded and provided with nuts 39 to clamp the sections between the plates 36.

Mounted in suitable bearings (not shown) positioned on the upper faces of the cross ties 18, are the shafts 40, and carried by the shafts are a series of saw blades 41 and 42; the number of blades corresponds to the number of spaces between the rings 31. Carried by each shaft 40, at its lowermost end, is a gear wheel 43, which wheels mesh with a gear wheel 44 carried by the shaft 20.

Positioned on the upper faces of the frame 1 is a pair of standards 45 and supported by the standards 45 is an angular shaft 46. A number of teeth 47 are carried by the shaft 46, the number of teeth corresponding to the number of spaces between the rings 31. Adjacent each end of the shaft 46 is a lever 48 and carried by the free end of the lever 48 is a weight 49. Carried by the machine frame 1 is a vertically disposed dividing board 50 interposed between the saw blades 41 and 42. Carried by the machine frame, adjacent its upper end, is a hopper 51 and secured to the shaft 15 and operating in the hopper is a screw-conveyer 52. The end of the hopper, adjacent the cylinder, is open and communicates with the interior of the cylinder 29. Carried by the machine frame 1, adjacent the lower end of the cylinder 29,

is a receiving-chute 53 open-ended at its top and arranged to receive bolls from the cotton after they have passed through the cylinder.

The side faces of the rings 31, adjacent their outer ends, are tapered so as to prevent choking by cotton dragged by the saws from within the cylinder.

Carried by the shaft 20 is a rotating brush 54, the bristles of which brush are arranged to remove such cotton that might gather in the teeth of the saw blades 41 and. 42.

In the practical operation of the machine, power is applied to the pulley 27 and all of the operating parts of the machine simultaneously driven. In this manner the cylinder is driven in the direction shown by arrows in Fig. 6, and, in the same figure direction-indicating arrows illustrate the direction of travel of the saw blades 41 and 42 and the brush 54.

After the machine is set in motion cotton within the bolls is fed to the hopper 51 and is moved through the hopper into the cyl inder 29 by the action of the conveyer 52, and by reason of the inclination of the cylinder 29, the cotton and bolls are carried by gravity and successively operated upon by the saw blades 41 and 42.

By reason of adjacent portions of the cylinder and saw blades 41 and 42 rotating in the same direction, and by reason of the peculiar construction of the ribs 32, the cotton is separated from the bolls by the teeth of the saws which engages and draws the cotton from its bolls, and, further by reason of the shape of the rear faces of the ribs 32 clogging of the bolls within the pockets formed by the ribs is prevented; and by reason of the ribs traveling in the same direction as the teeth of the saw blades the cotton and bolls not acted upon will be carried upwardly by the ribs and discharged again on to the saw blades. Such cotton as may be carried upwardly by the ribs and rings is cleared from the rings and ribs by the teeth 47. The loose cotton that clings to the teeth of the saws and is not discharged therefrom is cleaned from the teeth of the saw blades by the action of the brush 54.

The partition board 50 serves to prevent the cotton which might be centrifugally thrown from the saw blades 41 from being thrown against the blades 42, and thus carried upwardly into the cylinder.

If desired it is obvious the feed may be varied, either by changing the speed of rotation of the cylinder, or by varying the inclination of the cylinder by a manipulation of the jack 7. In this manner, and by reason of the length of the cylinder and the number of saws operating between the rings of the cylinder, all of the cotton is separated from the bolls and the cot-ton discharged into a suitable container located beneath the machine, and the bolls discharged from the cylinder into the chute at the lower end of the cylinder.
