COTTON-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 794,265, dated July 11, 1905.

Application filed January 6, 1905. Serial No. 239,872.

To all whom, it Inn/y concern.-

Be it known thatd, JEEEuRsoN SUMNER VVA'rsoN, a citizen of the United States, residing at Campbell, in the county of Dunklin and State of Missouri, have .invented new and useful Improvements in Cotton-Harvesters, of which the following is a specification.

My invention relates to acotton harvester, and has for its object to provide a simple and efficient machine of this kind.

A further object is to provide a picking mechanism which can be readily attached to an ordinary farm-wagon, to which the cotton is delivered after it is removed from the plant.

Improved details in the construction and arrangement of the various parts of the invention will be apparent from the detailed description hereinafter.

In the accompanying drawings, Figures 1 and 2 are front and side elevations, respectively, of the invention. Fig. 3 is a plan view. Fig. A is a sectional detail. Figs. 5 and 6 are details showing the arrangement of the supporting-frame.

Referring specifically to the drawings, 7 denotes the box of an ordinary farm-wagon, and 8 one of the hind wheels. A bracket 9 is secured to the side-board 10 of the wagon-box, at the top edge thereof, and supports a horizontal beam 11, which is bolted to the bracket, as at 12, and extends outwardly from the side of the wagon. A number of bolt-holes 13 are provided to permit lengthwise adjustment of the beam for a purpose to be hereinafter described. Below the bracket 9 is a bracket 14, which is secured to the side-board, near the bottom thereof, and supports a horizontal beam 15, which also extends outwardly from the side of the wagon. This beam receives a tubular casting 16, which is secured by pins 17 passing through the parts. The casting is adjustable lengthwise on the beam for a purpose to be hereinafter described, a number of pin-holes 18 being provided. The casting 16 and the beam 11 support two spaced vertical beams 19 and 20, which are joined at the top by a cross-beam 21. The parts herein described are the same on the side opposite to the one shown in Fig. 1, and they are the supporting-frame for the picker mechanism,

to be hereinafter described. The lengthwise adjustment of the beams 11 and the casting l6 herein described enables the supporting-frame to be extended outwardly from the wagon according to the width of the rows of plants.

At 22 and 2 3, respectively,'are indicated two endless belts or aprons, of canvas or other suitable fabric. These are secured to slats 24, extending across and carried by

sprocketchains

25 and 26, respectively, which pass over sprocket-wheels. Brushes 27 are mounted on the slats and operate on the plants ina manner to be hereinafter described. The top sprocket-wheels 28 are mounted on

shafts

29 and 30, respectively, journaled in bearings 31 on the supporting-frame, and the bottom sprocket-wheels 32 are on shafts 33 and 34:, respectively, journaled in suitable bearings at the bottom of the supporting-frame. shafts 29 and are provided at one end with bevel-gears 35 and 36, respectively, which mesh with bevel-

gears

37 and 38, respectively, on a shaft 39,journaled in bearings a0 on the supporting-frame. The shaft 39 also has a sprocket-wheel 41, which is geared by a chain 42 to a sprocket-wheel 4L3, fastened to the wheel 8. The

gears

37 and 38 and the sprocketwheel 4E1 will be feathered on the shaft 39 to permit adjustment of the supporting-frame, as heretofore described.

In the operation of the machine when the wagon is drawn over the ground the gearing herein described will cause the belts to travel in the direction indicated by arrows in Fig. 1, causing the ascending brushes to sweep the plants. The brushes come together, as shown, and thus forcibly engage the plants on both sides, whereby the cotton is effectively stripped off. To guide the plants between the belts, guides or fenders 44: are provided, which are carried by the supporting-frame in front.

At the top of the supporting-frame is a comb 45, which is presented downwardly and extends into the path of the ascending brushes carried by the outside belt 23, which brushes on passing through the comb are stripped of the cotton which they carry. This is then taken up by the ascending brushes on the inside belt 22, from which it is stripped by a comb 46, which is arranged at the upper end 100 The i of an inclined chute 47, extending into the wagon-box This comb extends into the path of the brushes onthe inside belt and strips them of the cotton thereon, which falls down the chute and into the wagon-box. As the belts cover the slats 24, no cotton can escape.

from the brushes as they travel toward. the combs, and there is consequently no loss.

The supporting-frame can be readily put on and removed from the wagon, and no specially;

constructed wagon is necessary, the invention being appllcable to any ordinary farm-wagon. MIHOIK changesmthe arrangement of the various parts herein described can; be made.

without departing from the scope of the in:

vention, and I-do not wish to limit myselfto. the precise construction shown excepl as in:

pair of endless belts mounted in theframe and carrying brushes to engage the plantszon opposite sides, a comb at: the top-01; the frame extending downwardly between the brushes,

anchute, extending into the wagon-body, and a comb at the upper end of the chute extendinginto,.the-path-.of. thebrushes on the inside belt.

2. In a cotton-harvester, the combination with-.awagon, of a frame carried thereby and extensible outwardly from one side thereof, a pair of endless belts mounted in the frame and carrying-brushes arranged to engage the plants on opposite sides, means for stripping the brushes, and means for delivering the cotton into the wagon.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JEFFERSON SUMNER WATSON.
