DANIEL RUGGLES, OF FREDERICKSBURG, ASSIGNOR TO EDIVAI-D S. RUG- GLES, OF FRIEDLAND, VIRGINIA.

COTTON-PICKER.

SPECIFICATION forming part of Letters Patent No. 242,560, dated June 7, 1881.

Application tiled March 2, 1881.

To alt whom it may concern:

Be it known that I, DANinL RUGGLES, a citizen of the United States, residing at the city of Fredericksburg, in the county of Spottsylvania and State otVirginia, have invented a new and useful Cotton-Picker, or machine for picking, extracting, and harvesting lintcotton from the boll or capsule when matured and ripe, of which the following is a speciiication.

My invention consists ot'a lint-cotton picker, as a machine for automatic action, and as a substitute or to supplement the human hand in picking and gathering lint-cotton from the cotton-boli in the field, with a view ot' facilitating harvesting. I accomplish these objects bythe mechanism illustrated in the accompanying drawings, in which- Figure l represents a longitudinal section ot' the entire machine. Fig. 2 is a longitudinal elevation of a grappling-claw. Fig. 3 is an end view of the revolving` disk, with its cap. Fig. 4 shows a modilied l'orm of the screw or fork, with its disk.

The same letter refers to corresponding parts of the machine.

A is a hollow cylinder, ofany required length and diameter, admitting ot' section al extension.

B is a piston-rod, admitting also ot'sectional extension, carrying a spiral spring, a., and both contained within the cylinder, revolving freely in it. The piston-rod carries the slide U, in which it revolves between two washers pinned to the rod. Said slide has slotted projecting arms c c, which are pinned to the slotted grappling-claws F F at Gr G, admitting ot' movement in the slots as the piston-rod is carried forward and back within the cylinder,

bearing the slide C with it, on which one end of the spiral spring rests, while the other end is attached'to the piston-rod, so as to close and extend with it.

F F are two grappling-claws with slots G G, pivoted fulcrums ff, made springs at b I), closing and grasping at e, when the piston-rod presses forward the slide (l. v

D is a screw or fork, screwed to the pistonrod at E, and projecting its prongs through the orifices h h in arevolving disk, H, fastened (No model.)

by a cap, I, and is plunged by the spiral spring 5o into the cotton-boil e, while held by the grappling-claws, and extracts the cotton when with drawn, the disk sweeping it oft', and it drops into the netting d, while the grappling-claws open again. i represents a cutter attachment for the claws.

The manner ot' operating and using my invention is as follows: Grasp the cylinder with the left hand and the piston-rod with the right 5 press with the spiral spring and carry 6o forward the slide G as a wedge, closing the grappling-claws F F upon the cotton-boli e, into which the lint screw or fork plunges at the saine time with a revolving motion, and by revolution extracts the lint-cotton from the cotton-boli; then withdraw it by the piston-rod toward the disk H, where it is swept or discharged from the prongs of the lint screw or fork as they are withdrawn in the orifices h h, with their points still projectingslightly 7o through the disk, while the lint-cotton drops into the small netting d., or other receptacle. The grappling-claws open at the same time and are adj usted for closing on another cotton-hell.

Without the cotton-lint screw or fork the machine is adapted for picking fruit.

I claim as my invention and desire to secure by Letters Patent- 1. The combination of a hollow cylinder, A, containing arotatingand revolving piston-rod, 8o B, provided with a spiral spring, a, operating a rotating screw or fork, D, a revolving disk,

H h, fastened by a cap, I, at the end H ot' the cylinder, and slide C, with slotted arms c c, connected by pins g g with slots G Gr in the grappling-claws F F, pivoted at ff as fulcrums, made springs at b b, and operated as hereinbefore described.

2. 'Ihe combination of a hollow cylinder, A, containing a revolving and reciprocating pis- 9o ton-rod, B, provided with a spiral spring, a, operating a rotating screw or fork, as a hand cotton-picker, to extract cotton from the cotton-bell e, with a rotating disk, H h, held by the cap I, with a netting, d, to receive the cotton, the grappling-claws F F, made springs at b b, and pivoted as levers, with fulcrums at ff, for opening, closing, and grasping the cotton-boil, the slide C o c, in which the pistongovern the motions and action of the graprod revolves, operating substantially as herepiing-claws F F, with their cutter attachments lo inbefore described. i, operating in combination substantially as 3,. The combination of a, hollow cylinder, A, hereinbefore described.
