COMBINED COTTON CHOPPER AND OULTIVATOR.

Specification of Letters Patent. Application filed September 17, 1906.

Patented Feb. 5. 1907.

Serial No. 334,830.

To all, whom, it may concern..-

Be it known that we, N nw'rox K. Ronna'r- SON and Isaac WV. Jonas, citizens of the United States, residing at Sidney, in the.

county of Comanche and State of T cxas,

have invented certain new and useful Imrovements in a Combined Cotton Chopper and Cultivator, of which the following is a specification, reference being had therein to the accompanying drawings.

our invention relates to improvements in cotton choppers and cultivators, one of the objects being to provide a device of the char 1 holding said wheel in raised or lowered position, and also means whereby said rideican readily raise or lower the cultivatortcctn.

Further ob ects and advantages of the in vention, as well as the structural features by means of which they are obtained, will be made clear by an examination of the following specification, taken in connection with the accompanying drawings, in which Figure l is a top plan.

elevation, partly in section.

Referring to the drawings, 1 designates an axle having thereon wheels 2, and pivotally mounted on said axle by means of iollars 3, formedintegral therewith, is an arched-shaped frame 4, in the top of which is dovetailed the rear end of a tongue 5, said tongue having an oblong slot 6 tlxci'ethrough. Secured to the tongue is a cross-piece 7, provided at each end with rectangular slots 8, through which pass depending bars 9, the upper ends of said bars being cut away to form necks l0, and having enlarged heads ll, whereby they are held in place in said slots. Pivotally mounted on the lower ends of said bars 9 are parallel bars 12, extending rearwardly and having their rear ends 13 apertured to receive the collars 3, by means of which they are pivotally suspended. Upon the depending bars 9 and the rearwardly-projecting bars 12 may be adjustably mounted in the usual manner the draft connections to which the draft-animals are attached.

Within the arched frame 4 and pivotally lower end of which Fig. 2 is a side elevation, partly in. section; and Fig. 3 is alront 1 mounted on the axle l is an oblong frame 14,

having its rear end tapering to a point, and

. fixed on said frame is a seat support or frame 15, having a seat 16 for occupancy by the rider and operator. ltotatablc in suitable bearings in the front cross-piece of said frame l t is a shaft l7, on which is fixed a 1chopping-whecl 18, the periphery of said wheel being provided with curved hoes or chupping-blades 12), which are preferably removably mounted in order that they may be taken off and replaced when rendered unopei ativc by wear and for the purpose of repair ing or sharpening same. The chopping hoes or blades 19 may be rcmovably mounted in any suitablemanner; but, as illustrated, they have their inner ends driven into the rim or E v ,7 periphery of the wnccl 15. ()n tne rear end of said shaft is 'flXOtl a gear-wheel 20, meshing with another gear 21, fixed on the axle l to rotate therewith, the two gears comprising a miter-gear. When the machine is in motion, the revolving of the axle cts the gears in meticu, thcscby revolving the shaft 17 and cansing a corresponding revolution of the chopping-wheel, as will be obvious.

Pivoted at one end on the inside of the parallel longitudinal beams of the frame 14. is a frame 22, carrying depending arms 23, on the are fixed the cultivator blades or shares 24. These shares may be fixed on said arms or remcvably secured thereto, as may be found most expedient or desirable.

livctcd on the axle l is a lever 25, resembling a bell-crank lever, the rear arm of which extends under the rear part of the frame 22, and the forward arm, which projects up wardly, is provided with a footrest 26, whereby said lever is operated to raise the rear end of said frame 22 whenever the rider desires to raise the cultivator blades or shares 24.

Mounted on the rear end of the tongue 5 is a ratchet-segment 27, provided with a plurality of notches for the reception of a springactuatcd latch 28, connected with the ordinary latch-handlc 29, the latch-handle being pivoted on a handle 30, which is fornted integral with a longitudinally-extcnding lever 31, pivoted on said segnent. The forward end of said lever is divided or forked, as at 32, and each fork-section has an arcuate slot 32). livotally 'nountcd between the forked ends of said lever 31 by means of a pin 34, which travels in the arcuate slots 33,

isa

' scribed, a frame, an

vertical link-bar 35, which extends downwardly through the oblong opening 6 in the tongue. The lower end of this bar is cut away and provided with an opening, which serves as a nearing for the forward end of the shaft 17, said bar being held on said shaft by means of a pin 36 or by any other suitable means. Secured to the outer edge of the lower end of the said bar 35 is a shield 37, the object of which is to prevent the dirt from coming in contact with the forward end of said shaft and with said bearing. As a brace, and also for the purpose of securely connecting the tongue 5 with the arched frame 4, a curved rod 37 passes through said tongue, and has its ends secured to said frame 4.

In operation, when the rider desires to raise the chopping-wheel 18, so that the hoes or chopping-blades 19 will not contact the ground, he pulls the handle 30 toward the rear of the machine, and raising the forward end of the lever 31, which in turn raises the bar 35, thus elevating the shaft 17, 011 which the chopping-wheel is mounted. By operating the handle 29 the latch-bar may he raised or lowered. As this latch-bar is adapted to engage the notches on the ratchet-segment 27, said segment and the bar 28, comprising approximately a ratchet and pawl, the chopping-wheel may be held in any desired position, either raised or lowered, as will be apparent. By sliding the pin 34 in the slots 33 toward the rear of the machine the vertical movement of the other bar 35 is limited, and the wheel is held in more elevated position when the forward end of the lever 31 is lowered to its utmost extent.

From the foregoing it is thought that the construction, arrangement, and operation of our improved cotton chopper and cultivator will be obvious to those skilled in the art, and. further explanation is not deemed nec essary.

Having thus described our said invention, what we claim as new, and. desire to secure by Letters Patent of the United States, is

1. In a machine of the character deaxle, supporting-wheels upon the latter, a second frame pivotally mounted upon said axle, a longitudinallyextending shaft journaled in hearings upon the front end of said pivotally-mounted frame, a pinion upon the rear end of said shaft, a gear upon said axle in DIGSll with said pinion, a portion of said sha t, a lever mounted upon the first-mentioned frame and formed with a segmental slot, means for locking said. lever against movement, and a link having its lower end provided with a hearing for the this has the effect of rotary cutter upon the front front end of said shaft and its upper end provided with a pin to engage the slot in said lever, substantially as described.
