fication, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in cotton-picking machines, and has for its object to construct a cotton-picker that will eflectuallv ick and deposit the cotton from the en 0 ls into a suitable receptacle and wi I perform the above operation. without injuring the green bol s. blooms, orstalks of the cotton-plants.

A further object of the invention is to construct a ,c'ottonicking machine that can be readily and easil; adjusted to conform to the height of-the cotton-plants and that will be of the lower carrier-arms.

provided with a series of picker-fingers to engage the open bolls and remo've t e cotton therefrom and a novel construction to remove the cotton from the fin ers and deposit same in the receptacle provi ed therefor.

The invention finally consists in the novel construction, combination, and arrangement of parts throughout to be hereinafter more specifically described, and particularly pointed out in the claims.

By referring to Fig. 4 of the drawings it will be observed that the arrangement of the lug f u on the arm (I is such that it will engage the u c" from a different position from that of the 11g 6' of the arm (1. By this arrargeincnt the carrier is turned one-half revolution to bring the cogs of the carriers into e11gagcmcnt again with the segmental toothed portion of the arms for rocking the carriers. This arrai gemcnt also revents the carriers from turI irg freely. 0th the upper and lower arms are secured to the carriers by a fulcrum-hearit gf (see Fi 17,) havi'. g a shaft portio'. if provided wit 1 an exterior air- Llllitl groove f which receives a pitrj, assing throu h the end of the carrier and 00ki: g the fu crum-bearin The arms d and d are pivotally secure to this fulcrum-bearing. On'the carriers e e is secured a series of picker-fingers f provided with projecting pouts g g, cxtendirg in longitudinal alinement with the firgers. These fingers f are arrarged at a slight incline and are provided with bevel gear-wheels g g, resting'on washers or bushings 9 said Wheelsengaging in the secured to the frame oflthe machine- In which may be employed in lieu of the bevelg'ears g, the cogs of the racks g of course in this corstruction bei g dispensed with r 1',

The front part of the machine is supported screw-threaded shaft-h, operating atjts lower 1 end in the block it, secured to the pgat'eh and I provided on its upper end with 'a' eye] gearwheel h", adapted to mesh with a'g ar wheel I secured on the shaft, whichis s'lipported by a brace h", fastened to the upper brace g", said shaft. being adapted to receive ja erank shaft h and adjust the forward end bfthe frame, as may he desired, either upward or downward.

Within the frame at the front of themachine is provided an mverted-U-shaped flartoothed racks 9 said racks being curved and Fig. 5 ,I have shown friction-rollersg g,

ing sheeting or casing 11 with the smaller end toward the rear of the" machine, forming a guide to carry the plants to the fingers. Arranged within the wheels 6 b is an ordinary clutch-gear 11, having an operating'handle 10, employed for engaging and disengaging the bevel-gear a, and a to impart motion to the mechanism and discontinue the same. This clutch-gear may be arranged with its operating-handle passlng to an suitable point on the machine that will be convenient to operate the same. At the rear of the machine the frame portion is constructed with an n wardly-extending yoke 1c, which is of sell cient height to allow the arms to clear the some, said yoke being rigidly supported by hraccs 7: k, secured to the upright standards of the frame portion, this construction serv- On the underneath side 0 the toothed racks g, at. the forward end of each, is secured a spring is, (see Fig. 23 having a downwardlv-proj ectin tooth k, which engages the bevel-gear 9' an assists the same into an engagement with the teeth of, the rack by turning the wheel into such a position that its teeth are ready to em gage with the teeth of the rack. The ends of the carriers are provided with a hole 1:, (see Fig. 17,) which is adapted to receive the shaft In Fig. 2l,whiol1 is a modifies tion, as be I ear-wheel l is employed to mesh with a hevelear 3*, that will be mounted on the shaft b in lieu of the norm 6 and screw a, as shown and described throughout the specification. The wheel 5 secured on the shaft 0, is provided on one side with a series of beveled teeth 1, which are ndaptedlo engage the lower carrier-arms (1" and assist the some on the slide 'i.

f '0 will now assume that all the parts have lioon secured in their respective positions and the machine proper is in motion without the different parts heing'in operation.

The clutch is thrown in engagement, causing the hovel-gear o to engage with the bevelgoal a, and as the machine moves forward the shaft a will be rotated causing the wormscrew of to engage in the worm-wheel b and communicate motion to the vertical shafts b, causing same to revolve and rotate the arms carrying the picker-linger carriers. As these carriers revolve the wheels g y will engage in the toothed racks g" as they pass between the curved guides, (shown more especialiy'in Fig. 25,) and this in turn communicates motion to the picker-lingm's, causing; the same to revolve simult sineously. The machine isdrawn across the field with the some straddle of a row of plants, so as to bring the plants within the U shaped casing 11", thus bringing the open bolls in direct ontaot with the wicker-lingors, which engage in the said hols and by reason of the projecting points wind the cotton on the lingers as they are revolved and carry the same around to the comb, the fingers of which, by reason of the incline in the picker-fingers, will engage the said pickerfingers at the rear, and as they continue to rotate and descend on their movement, keeping the picker-fingers and comb-fingers in contact until past engagement, the cornbfingers will thus be permitted to effectually strip the cotton from the picker-fin ers and allow the cotton to fall into a snitab e receptacle provided therefor.

During the time that the bevel gear-wheels g are in engagement with the toothed racks g the teeth 2 of the lower arms, the teeth f of the upper arms will be in engagement with the teeth a serving to rock the carriers, the picker-fingers retaining an inclined position ,throughout the length of the cog-racks g,

of the drawings by dotted lines. At the time that the bevel-wheels 9' leave the racks g the respectively, have passed the point of contact with the teeth e and the lug eand of the arms come in engagement with t e lugs r ")f the carriers and operate the carriers, so as to throw the free ends of the picker-finers toward the drive-shaft b toward the rent of the machine, which position they retain until the bevel gear-wheels of the fin ers again come in contact with the racks, w ien they will be reversed to the former position to again engage the cotton by reason of the teeth hein in engagement again. As the Zbevehwhee s on the picker-fingers are about to enter the toothed racks the spring k engages the bevel gear-wheel before it reaches the teeth of the rack, compressing this spring, and as its tooth Z-r" passes out of'ongagement with the bevel-gear g the action of the spring in returning to its normal position ro tatcs the picker-fingers and forces the bevelwheel more readily into engagement with the teeth of the rack and prevents any lost motion at this point. As the bevel-gears g g enter into engagement with the tooth-racks the picker-fingers will he revolved and will )e entered into the hells in an inclined position, thereby causing the projecting points g, g of the iingersto more readily engage the cotton and to effectively remove the same from the bolls.
