COTTON-PICKER.-

SPECIFICATION forming part of Letters Patent No. 647,818, dated April 1'7, 1900.

Application tuen July 21. 1899. serai No. 724.6458. tno model.)

To all whom t may concern:

Be it known that I, WILLIAM J oHNso DYER, of Shreveport, in the parish of Caddo and State of Louisiana, have invented a new and Improved Cott0n-Picker,of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved cotton-pickenhwhich is simple and durable in construction andarranged to insure a clean and thorough removal of the bolls from the cotton bushes or plants whether the latter are high or low and without danger of tearing or otherwise injuring the fibers of the lint or the growing plant.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claim.

A practical embodiment of the invention is represented in the accompanying drawings, forming a partof this specification, in which similar characters of reference indicate correspending parts inV all the views. y

Figure l is a side elevation of the improvement. Fig. 2 is a sectional plan view of the same on the line 2 2 in Fig. l. Fig. 3 isa transverse section of the same on the'line 3 3 in Fig. l. Fig. 4 is a rear end elevation of the improvement, and Fig. 5 is an enlarged sectional view of one of the pickers.

The improved cotton-picker is mounted on a vehicle having a frame A, connected at its front end by a fifth-wheel device with lthe front aXleB, carrying the front wheel C, and on the rear end of said frame A is journaled the rear axle B, carrying the rear tractionwheels C.

On the rear portion of the frame A is mounted a box D for receiving the lint after removal from the cotton-bolls, as hereinafter more fully described, the' front end of the box D being open and the rear end normally closed by a suitable door E, opened from timeY to time to permit the removal of the accumulated cotton. In the front of the boX D are arranged two sets of cotton-pickers F, made circular in shape and projecting with their outer edges a distance beyond the sides of the boX D of the frame A, asis plainly indicated in the drawings, so that said pickers can readily pass in between the branches of the cotton-plants to remove the bolls therefrom for final delivery to the box D.

TheV pickers F on each side of the machine are secured on a vertically-disposed shaft G, journaled in suitable bearings on the frame A, and on the lower end of each shaft G is secured a bevel Vgeanwheel H, in mesh with a bevel gear-wheel ll', secured on a transverse shaft I, journaled in suitable bearings attached to the under side of the frame A. On the shaft I is secured a bevel gear-wheel I', in mesh with a bevel gear-wheel I2, secured on the forward end of a longitudinally-extending shaft I3, likewise -journaled to the under side of the frame A. On'the rear end of theshaft IS is secured a bevel gear-wheel I4, in mesh with a bevel gear-wheel I, attached to the rear revolving axle B', so that when the machine is drawn forward over the ground the traction-wheels C cause a rotation of that the cotton lint is pickedV from adjacent sides of the two rows.

The rotary motion of the lat- As shown'in the drawings, the pickers F on a shaft G are placed a suitable distance apart, and each picker is provided with a solid core or center F', having its top and bottom diverging fronithe outer edge toward the center of the picker, the said top and bottom being covered by aleather or other covering F2 and having picking devices F3 in the form of teeth extending outward from said coverings. (See Fig. 5.)

When the pickers, constructed in the manner described, are rotated while the machine is drawn forward, it is evident that the outer sides of said pickers readily pass between the branches of the bushes, and the picking devices F3 easily come in contact with the lint and remove it from the bolls. The cotton lint thus removed from the bolls by the pickers is carried by the latter inward to be removed IOO 2 i l i 647,818

from the pickers by revoluble circular brushes J, secured on vertically-disposed shafts K,

j ournaled in suit-able bearings in the frame A.

Each shaft Kv is provided at its lower end with a bevel-pinion K', in mesh with a bevel gear-wheel K2, secured on the shaft I, so that when the latter is rotated, as previously explained, a rotary motion is given by the bevel gear-wheels K2 and the pinions K' to the shafts K and the sets of brushes 4or sWeepers J,'

mounted on said shafts and extending with their beveledtops and bottoms betweenyadjacent pickers F, close to the outer ends of the teeth thereof, so as to readily remove the lint and carry it inward by the revolving pickers.

lThe peripheral faces of the revol'uble brushes or sweepers J extend close tothe shafts G, carrying thelpickers, so that the lint is all removed from-the faces of the pickers j Without danger of clogging, and said lint is delivered by the brushesto the box D, 'in

` Vwhich it canaccumulate.

The gearing for the-shafts G and'K is so proportioned that the shafts G rotate at a lower speed than the brushes J to cause a ready removal of thelint from the 'pickers when themachine is in'use.

In order to prevent thelint from flying sidewise andl outward from the brushes and to prevent clogging of Vthe brushes and pickers @by thelint, I provide the angularly-disposed flanges L on the forward ends of theksides of the `box D, the fian ges extending to the pickershafts, with eut-out portions for the passage of the pickers. The flanges are preferably of canvas; but other material may be employed.

Having thus fully described'my invention, I claim as new and desire to secure by Letters Patent-4 The herein-described cotton-picking machine, 'comprising the wheel-supported box open at its front end, vertical shafts journaled f at the sides of the box at the open end, a series of spaced-apart picking-disks secured on 'each shaft and each vformed with a solid core whose top and bottom diverge from the edge toward the center and are provided with piekin g-teeth, two vertical shafts journaled in the open end of the box between the picker-shafts, a series of spaced-apart brushes on each of said latter shafts and having beveled tops and bottoms conforming to the pickers and'side edges corresponding to the spacesbetween the latter, pinions on the lower ends of all the shaft-s, a transverse shaft having beveled gearwheelsrmeshing with the pinions, the-gearwheels being so 'proportioned with respect to the pinions that the picker-shaftswill rotate at a lower rate of speedthan the brush-shafts,

- and gearing connecting said transverse shaft .with the traction-axle of the picking-machine,

as set forth. y
