IMPROVEMENT lN PICKING COTTON FROM THE BOLLS IN THE FIELD.

Specification forming part of Letters Patent No. 7,63], dated September 10, 1850.

To altavhomft't may 'chncern: I r 7 Be it known that We,'SAM. .S. REMBERT and JEDEDIAH PRESCOTT, of Memphis, in the county of Shelby and State of Tennessee, have invented a new and improved machine for picking or gathering cotton from the bolls upon the. stalks of the plant while they are standin g in the field; and we do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings, making a part of this specification. m

Figure l is a perspective view of our cottonpickeryFig. 2, an elevation of its rear end,

and Fig. 3a longitudinal vertical section through the center of the machine.

Similar letters indicate like parts in all the figures. ()ur cotton-pickerriscomposed ot' alrameof suitable strength, mounted upon the axle of two (or more) high wheels, substantially as represented in'the drawings, with which frame arecoinbined the whi ppin g-sh aft i\(l,theinclinedgathering-planes L L, the picking-disks A A and picking-cylinders O (J, the stripping-cylinders'B' D, and cotton-receptacles J K, arranged and operating substantially in the manner reprcsen ted by the drawings, and hereinafter set forth. I

The wheels H H must be ofsuflicient height to enable the axle-tree to pass above the tops of the cotton-plants, and the-distance that they are placed from each other is equal to the space between the different rows of the cotton-plants. The planes L L incline inward toward each other from their frontto their rear ends, and

are 'made fast to descending portions of the supporting-frame. When the machine is operated in the cotton-field, the wheels pass between a couple of rows and embrace a row of cotton-plants between the inclinedplanes L L. The cotton-plants are first operated uponby the whipping-cylinder M, the switches radiating from which detach the leaves from the plants and open the bolls to the free action of the pickers.

Thepicking-disks A A. aresecured tothe inner ends of horizontal shafts placed obliquel y to each other and secured in suitable bearings; The faces of the disks A A are armed with sharp teeth, aiid descend a sufiticient dis-' tauce below their axles to take hold of the lowest bolls upon the -cotton-plants. By the forof spring-bearings.

ward movement of the machine'thepickingdisks A A are rotated, and the teeth upon their faces take hold of and draw the cotton from the bolls an'd carry it upward to the strip pers or winged cylinders B B, which, by their rapid revolutions in immediate proximity to the faces of the disks, remove the cotton therefrom and deposit it in the receptacle J.

Near the rear end of the machine are placed the vertical picking-cylinders U C, which have their peripheries armed with sharp pickingteeth. The picking-cylinders U 0 project inward through openings in the portions of the rear ends of the planes L L, that form the sides of the cotton-receptacles K K, a sufiicieut space being left at the rear of the cylinders for the cotton gathered by the teeth on their peripheries to pass into the receptacles K K. The cotton is removed from thecylindersO O by the rapidly-revolving strippers or winged cylinders D I), placed in close proximity to the peripheries of the cylinders within the cottonreceptacles K K y We shall generally placethe disks A A upon their axles in sucl'ra manner that their positions can be adjusted in or out, or in such a manner that they shall be=forced inward by springs and rendered self-adjusting in their positions. is shalLalso secure the pickingcyli'nders O O in bearings arranged in such a manner that theirflpositions can be adjusted in or out, or in such a manner that'they will be self-adjusting in their positions by the aid We shall use the pickingdisks in combination-wit'h the picking-cylinders in the same machine, or we shall employ either a series of picking-disks or a series of picking-cylinders in a machine, as we may deem expedient, as there is no ditt'erence in principle, whether we make use ot'disks'or cyli'n'ders in our cotton-picking machine for gathering the cotton. from thebolls.

Our cotton-picking machine may be'muliiplied and exteuded'to such a width as to embrace several rows of cotton-plants at once.

The picking disks and cylinders and the strippers or winged cylinders are driven by bands connecting them with the drum E, as represented. The drum E is'driven by the friction-pulleys FF at the extremities of its shaft, bearing agai-nst the friction-wheels G G, secured to the spokes ot' the Wheels H H or, instead of the frictionfwheels for imparting motion to the drum E, cog-wheels may be employed.

Having thus fully described our machine for picking or gathering cotton from the bolls upon the stalks of the plants while they are standing in the field, what we claim as our invention, and desire to secure by Letters Patent, is-- 1. The combinatioirof the whipping-cylinder M with the picking-disks A A and the strippers B B, and also the combination of the whipping-cylinder M with the picking-cylinders 0 (J and the strippers D D, substantially in the manner and for the purpose as herein set forth.

2. The combination of the picking-disks A :K, substantially in the manner and for the purpose herein set forth.

tion of our machine t'orgathering cotton from the bolls in the field we have hereunto subscribed our names.
