COTTON-PICKER.

SPECIFICATION forming part of Letters Patent No. 364,440, dated June 7, 1887.

Application filed NLYOllll cr 9, 1856. Serial No. 21 ,413. (No model.)

' have invented a new and useful Improvement in CottonPickcrs, of which the following is a full, clear, and exact description.

My invention relates to cottonpickcrs, and has for its object to strip the cotton-plant, upon maturity, of the hulls containing the fiber, automaticall y separate the fiber from the bulls, discharge said hulls from the picker, and deposit the clear fiber in a compartment formed therein for the purpose.

The invention consistsof the combination of parts, including their construction, substantially as hereinafter set forth, and pointed out in the claims. v

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my cottonpicker, and Fig.2 a central longitudinal vertical section thereof. Fig. 8 is atransverse seetion through one of the strippers. Fig. 4 is a I rear elevation of my machine, and Fig. 5 a partial transverse section through the rear portion of the body. Fig. 6 represents a central transverse vertical section through the complete machine on the line at x in Fig. -2.

In the construction of my cotton-picker the body A, fitted with suitable wheels, I), (a single centrally-arranged one being applied at the forward end,) is usually provided wit-h a horizontal base, inclosed sides, and a top surface, 2', adapted to incline at a decided angle from the rear downwardly to the front, the upper and lower ends of said inclined surface being positively curved at their intersection with the incloscd front end of said body and the partially-inclosed rear end thereof.

The inclined top surface, 11, which properly constitutes the face of the machine, is provided with a series of longitudinal slots extending approximately from end to end the width of said inclined face, whereby a series of Iongitudinal bars, 7a, is formed, imparting to the entire face of the machine a grate-like appearance.

Within the body A, thus constructed, the

main axle G is journalcd, adapted to extend beyond said body at each side. Upon one. extended end of said axle O a grooved pulley, t, is keyed, while to the other traction-wheels (I may be attached. Between said tractionwheels the d rivers seat 2 is usually located at an elevation above'the axle,and secured thereto in any approved manner, the draft-pole l being attached to the uprights of said seat or to the axle itself.

Motion is conveyed to the main axle G through the t-ractionwheels (1, which are adapted to travel each side of a line of plants having been previously stripped, thus allowing the body A to be drawn between said stripped row and the line of plants from which the cotton is to be gathered.

Upon the main axle 0, between the inner traction-wheel, cl, and the side of the body A,

a gear-wheel, c, is keyed, adapted to mesh with a smaller toothed wheel, f, keyed upon the outer end of a shaft, y, journaled in the said body A,near the rear upper end thereof, which shaft 9 is adapted to carry a drum, h, within said body A. The said shaft is also provided with a second gear, in, upon its opposite end, whose function will be hereinafter set forth. Another shaft, Z, parallel with the shaft g, is journaled in the body A, the two shafts being in aplane parallel with the aforesaid surface t" of the said body, and adapted to carry a similar drum, 7c. The purpose of the said drums h and is thus mounted is to constitute carriers for an endless belt, '5, of leather or other eqnivalent material, adapted to travel over said drums parallel with the inclined slotted face 'i. The endless belt 2' is provided longitudinally with rows of vertical teeth having sharp an gular hooklike points inclined to the rear ofthe machine, adapted to project upward above and between the longitudinal bars It of the inclined face i, and act to carry the cotton-bolls delivered upon the inclined face of the body A to a chute or spout, as hereinafter described. The longitudinal rows of teeth 9 upon the endless belt 2' are equal to the number of slots formed in the inclined face i, as the said teeth are adapted to travel in the said slots.

Brackets WV are provided on the rear end of the body A, adapted to extend upward therefrom, which may be connected by an ordinary brace, c. The tops of said brackets are made to slant from rear to front at the same angle as the slotted face i, and to each side, at the front of said body, separate upwardly-extending standards df are attached.

Longitudinal shafts c o are journaled at one end in the vertical standards d, and at the other end in beari n gs upon the brace e of the brackets WV, parallel with the inclined slotted face i, the said shafts having keyed upon their rear ends, which project over said brace e, bevelgears b, which bevel-gears b are adapted to mesh with similar bevelgears, a, keyed upon a transverse shaft, '0, journaled in bearings upon the rear brackets, WV, and provided with a grooved pulley, t, secured to its projecting end. Motion is conveyed to the longitudinal shafts c c from the main axle 0, through the medium of the said upper transverse shaft, 22, by a belt, 11., adapted to engage the grooved pulley t of the main shaft and the similar pulley, z, of the said upper transverse shaft, 12.

The above-mentioned longitudinal shafts c c are purposed to carry strippers f which consist ofa suitable body, f, encircling the shafts c provided with radial arms carrying a series of upwardlycurved fingers, h, as shown in Figs. 4 and 6. The said strippers are adapted to engage the plants, strip the bolls from them, and deliver the same upon the inclined slotted face t" to the picking-teeth g.

A spout or chute, 1", provided with one open side and a contracted open bottom, is hinged to the rear brackets, W, so as to form a chamber behind the rear curved portion of the face i, and extend a distance down the end of the body to retard the passage of the bolls out from the machine, in order that the picking-teeth g may take the cotton fiber from the bolls crowded into the chute or spout.

A brush, 1), is fitted upon a shaft, 0, journaled in the rear portion of the body A, in such position as that the said brush will engage'the picking-teeth g as they carry the cotton fiber within the said body, and thesaid shaft 0, extending through the side of the body upon one side, is provided with a toothed wheel, 12, adapted to mesh with the similar toothed wheel, m, above it, connected to the drum-carrying shaft 9, hereinbefore described, by which the brush 12 also receives motion from the main axle O.

Inthe rear of the body A, a chute, S, is provided about centrally with the revolving brush p, through which any leaves, light twigs, or trash escape, drawn in with the cotton fiber, while the cotton fiber itself, weighted with the seed, passes down with the brush and drops into a lower and larger chute, M, from whence it is taken out and disposed of as desired.

The direction in which the strippers are revolved is illustrated by arrows in Fig. 6, as are also the movements of the principal gearing likewise in the other figures.

The draft-pole may, if desired, be attached centrally to the body A, and but one tractionwheel, (I, be employed to drive the main axle, or said axle may be driven from the wheels I) of the body. i

In the operation of my cotton-picker, constructed as shown in the drawings, the side traction-wheels are adapted to travel one upon each side of a line of plants from which the cotton has been previously picked, the body of the machine being entered between saidline and the row from which the product is to be gathered. tion-whecls the main axle O is operated, and from the said main axle motion is given the operative parts of said machine, which are arranged with respect thereto, as heretofore set forth. As the machine advances, the rotary strippers carried thereby are revolved in the direction shown in Fig. 6, the curved ends of their fingers pointing upward, thus revolving inward toward the center of the face i. The stripper upon the one side engages the plants as yet untouched and relieves them of the cotton-bearing bolls, delivering the same upon the inclined slotted face of the body A, while the strippers upon the other side gather any bolls remaining upon the previous]y-stripped row. As the bolls are delivered upon the inclined face i, the pickers carried by the endless belt 1 moving rearward, carry the cottonbolls and convey them within the body A. The same crowding in the rear chamber, 1, are retained therein sufficiently long to be engaged by the pickers, the hulls passing out therefrom to the ground. The cotton fiber, as it is conveyed by the said pickers downward, is removed therefrom by the rotary brush p,

the chaff gathered with the cotton, as it is relieved from the pickers, finding its escape through the chute or flue 8, immediately opposite said brush, to the outside, while the cotton rendered more or less heavy by the attached seed falls from the brush into the compartment M below it, from whence it is removed in any desired or convenient manner.
