" COTTON- To aZZ.whm it maj concern: I Be it known that I, Lnwrs. BLOUNT a citihave invented a certain new and useful Gotton-Picker, of which the following is a'speci- The objects of my invention areto provide pensive construction which is designed to be parted toitfrom a motor and which is so ar. ranged and constructed as to draw the vcotton from the bell throu h a cylinder and force it lnto a tube, from'w "ch it is delivered into a further object to provide a team;

ation whether manipulated by hand or driven with'a motorthat 1s, 1t is so arranged that the piston can be continuously operated either there will be no interruption in the process of removing the cotton from the bolls, and'thus enable the operator to rapidly pick the cotton.

My invention consists in certain details in nation of the various parts of the device, whereby the objects contemplated are ate pointedout in my claims, and'illustrated in- Figure 1 is aside elevation of the complete device withfportions of it: broken away and drawnin section to show detail features of 1t.-

v i 5, sh-W P1111011 51- T sfiheft. fih aa 5 'der 13 I'have provided a piston-rod 35,w-hich 'r'nounted on its outer end the fiy-wheel 28 andon its inner end the crank-wheel 29, which crank-wheel 29 is on the opposite side of the frame from the ears, pinions, and fly-wheel above mentioned.

' It will be seen that as the gears and are rotated the shaft 26 and the parts connected with it willbe rotated through the gear 27'. Rotatably mounted on the surface :of the crank-wheel 29, which is away from the frame 10 and near the periphery of said crank-wheel, I have provided a roller 30,

which roller is capable of longitudinal move 'ment in-a cross-head 31,'which is secured to a reciprocating b 'ar 32, which parts are so arranged that as the crankewheel 29 is rotated and-at the same time the roller 30 is moved longitudinally of the cross-head 31 the reciprocating bar will be driven longitudinally at the side of the frame. This reciprocating bar is slidingly mounted relative to the frame 10 by-means of-the bearings 33 and 34, which are secured to said frame. Y

Detachably connected with the end of the reciprocating bar which is nearest the cylinhas secured to its free end a piston-head 36.

.This piston-head is substantially circular in cross-section and-has extending outwardly from it a series of teeth 37, which teeth extend toward the piston-rod 3.5 at an angle of about forty-five degrees from the circular piston-head 36. These teeth are arranged in rows, so that they will operate freely between the rows of teeth on the interior of the cylinto one side of the cylinder-support 12 is a tube 38, throughwhich the cotton passes as it is drawn through the cylinder 13 by the toothed piston-head 36: At the outer end of v which has been the'tube 38 I have provided a series of hooks 39,.by which a bag'or other receptacle 40 is secured to the tube 38, into which the cotton picked by my mechanism is de osited.

the operation of-the device the operator grasps the handles 11 and 15 and operates through them the piston on one stroke of the rack-sector, and the operation of the piston is continued by the fly-wheel 28 as the racksector is made to take its return stroke through the manipulation of the handle 15.

keeps-the piston reciprocating between the The "next stroke of the rack-sector through the manipulation of the handle 15 continues the operation of the piston and the fly-wheel two driving strokes of the rack-sector 16.

the piston is reciprocated the piston-head 36 extends outside of the cylinder 13 and the teeth 37 catch the cotton to be picked and draw it from the boll on the return stroke, of the piston into the cylinder where the teeth 14 retain it against outward movement as the piston-head again moves outwardly. As the piston is reciprocated the cotton is drawn into the cylinder-head and there temporarily retained until it is forced into the tube 38 and allowed to drop into the bag 40 or some other receptacle provided for the purpose. It will be seen that the piston-head can be easily removed, so as to repair it, if any of the teeth become bent or twisted in operation by detaching the piston-rod 35 from the reciproeating bar 32.

In the modified form of the device the iston, the crank-wheel, the cylinder, and cy inder-support are constructed in the same way as in the preferable form. The frame is also constructed in the same Way, except that the handle 11 its omitted. In place of the gears 20, 25, and 26, the pinions 18, 24, and 27, and

the ratchet and pawl I have provided a gear 41, which is mounted on the shaft 42, which is arranged in the frame in substantially the same planeas the shaft 26. This gear 41 is in mesh with a gear 43, which is mounted on the shaft 44. This shaft 44 is driven from a motor 45, which is controlled by a spring maintained lever 46, operated by a fingerrod 47. This motor 45 is'driven by air or other power fed to it through the hose 48. A handle 49 is provided by which the operator supports the mechanism.

The operation of the piston device is the same in the modified form as in the preferable form, inasmuch as the piston is driven continuously by the motor, the means of cffecting the operation bein the only difference between the modified and preferable storm of the device.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States therefor, is
