COTTON CHOPPER AND CULTIVATOR.

SPECIFICATION forrnnggpart of Letters Patent No. 723,444, dated March 24, 1903.

Application iled January 6, 1902. Serial No. 88.680. (No model.)

to provide a device that is at all times under` the control of the operator.

Another object of my invention is to provide a device that hastwo wheels with slantingly-disposed rims, each wheel carrying a series of lever-operated and spring-returned cutting-blades, pairs of said blades on the two wheels swinging toward each other simultaneouslyand forming an equivalent to a pair of shears.

Another object of my invention is to provide means for actuating the above-described cutting-blades or preventing their operation, as the nature ov the work and the judgment of the operator may dictate.

Another object is to so construct the running-gear and connect it with the wheels carrying the cutters that said cutter-wheels may at all times straddle the row, notwithstanding the direction given' to the machine by the draft-animals. This is a very important consideration, because the rows are not always exactly straight, and thecomplete operation of the machine is at all times assured without the need of worrying the animals by having to make them follow the row.

A further object of my iuvention'is to provide vertically-adjustable cultivator-blades to follow the chopper, which may be raised and lowered at the will of the operator.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side view in elevation' of my invention; Fig. 2, a top plan View; Fig. 3, a detached view in elevation of the wheels carrying the cutting-blades and the frame in which they are journaled; Fig. 4, a top plan view of the vdevice with the chopping-wheels and frame removed; Fig.5,a detail view of one of the brackets and swivel-bars; Fig. 6, a detail view of a pair of cutting-blades; Fig. 7,.

a View of one of the rods carrying the cutthe frame of my machine, made, preferably,

of a rectangular form and has the draft-pole 2 secured to one end of the frame and braced by bars 3.

4 represents the operators seat, which is of any desired form and supported by the gooseneck 5 to the rear end of the frame 1. Midway of each side of the frame 1 are secured the brackets 6, in the arms of which are journaled the rectangular swivel-bar 7.

8 represents the driving-wheels, which are journaled on the arms 9, secured to said rectangular swivel-bar 7.

l0 represents a frame pivotally secured to the rod 11, which is secured through the sides of the frame 1, just back of the front end of said frame, said frame 10 having near its front and rear ends curved at bars 10a and 10b, respectively, which are segments of the same circle.

12 represents another frame narrower than the frame 10 and having its front and rear ends 12 and 12b curved in the same degree and direction as the parts 10L and 10.". y

13 represents a downwardlydepending bracket from each side of the frame 12, which supports the axle 14, on which is journaled the hollow shaft 14, and secured near each end of said hollow shaft 14a is a wheel 15, having a slanting rim 16.

17 represents a circular metal band mounted by means of the angular brackets 17a to the spokes of each wheel 15, said band being concentric with said rim 16 of said wheel l5.

18 represents rods journaled in the rim 16 r each rod 18 near the inner side of the lrim 16 of the wheel 15 and has a cutting edge 20a. The cutting-blades on the two wheels are arranged opposite each other, and when in operation, as hereinafter` described,swing across the median line between the wheels 15, and consequently are an equivalent to a pair of shears. f

21 represents a lever having the handle portion 21 and the two parallel arms 22 each fulcrumed in the bracket 13 on each side of the frame 12. The free end of each arm 22 is bent, as shown at 22, and is adapted to successively actnate the cutting-blades 2O by tripping the rod 18 and causing it to turn when'the lever is properly adjusted by the operator, so that the ends 22 of the arms 22 intercept the bent ends 18.

18b represents a coil-spring wound around each rod 18 and connected thereto at it-s lower end, while at its upper end it is secured to the band 17. The purpose of the coil-springs 18b is to return the cutting-blades 20 to their. normally open position, when the bent portions 18 are released by the ends 22 of the arms 22 `by twisting the rod 18 back to its normal position. p

The frame 12 and the parts connected therelwith rest upon the frame 10, the segmental cured to pins 26 in the center of said ends 12a always parallel.

and 12b. It will now be understood that the driving-wheels 8 and the cutting-Wheels 15 swing together, so: that the four wheels are This 'swingingis controlled by the operator, who places one foot on each pedal 27, connected, by means of the curved bar 27, to the swivel-bar 7. It will also be understood that by pivoting the frame 10 to the front of the machine, as above described, sufficient up-and-down playis permitted the cutter-wheels 15 to permit them to adapt4 themselves to the inequalities of the ground, means being provided, as will be hereinafter described, to prevent the Wheels 15 jumping upward too far, as might possibly be the case if a large stone or other obstruction be encountered.

28 represents beams pivoted to the rod 11 on each side of the cutter-Wheels 15, each having its rear end bent toward the other back of the Wheels 15, as shown at 28, and having mounted thereon a disk cultivatorblade 29. The beams 28 are raised and lowered by means of the bell-crank levers 30, fulcrumed to each side of the frame 1, as shown at 30, and connected to each beam 28 by means ofthe link 31, pivoted to said beam and t-he end of said lever 30.

32 represents a lever for operating the bellcrank levers 30, which is fixed to one end of the rod 33, jonrnaled in the sides of the frame 1, near the rear end thereof, and 34 an arm secured to the opposite end of the rod 33.

The lever 32 and arm 34 have each a rod 35 pivoted thereto and having a redncedand rounded end 35, that tits into an eye 30" in the upper end of the bell-crank lever 30 on that side of the machine.

36 represents a coil-spring wrapped around each rod 35 and secured to the bell-crank lever. The purposes of this construction of rod and spring are threefold-first, the tension of the spring assists in lowering the beam when the lever 32 is thrown back; second, the tension of 'the spring serves to give the cultivator-blades an operation similar to a spring-cultivator, holding the cultivatorblade in the soil except when a hard obstruction is encountered, when the bell-crank 1ever 30 is moved back on the reduced portion 35, passing through the eyeV 30, the spring instantly returning the blade to its normal position when past the obstruction, and, third,-the shoulders 35, formed by the reduced portion 35, push the bell-crank levers back when the lever 32 is thrown forward, thus raising the beams.

37 is an ordinary construction of segmental rack for adjusting the angle of the operatinglever 32 and the consequent height of the disks 29, 37 representing a stop which is used when the blades 29 are not in operation.

38 represents a bolt slidably mounted in brackets 39 on the side of the lever 32 and held in rack 37 or stop 37 by means of the coil-spring 40 bearing against the upper bracket 39 and secured to said bolt 38 through a hole therein. The bolt 38 is Withdrawn from engagement with said rack or stop 37 by means of the lever 41, pivoted to the lever 32 nearits free end, and the link 41, connecting said lever 41 and the head of the bolt 38.

42 represen ts a chain connecting each beam 28 with the rear of the frame 10, said chains and beams 28 acting as drags to prevent said frame 10 being thrown up too high should the wheels 15 strike an obstruction.

By the construction above described it will be readily seen that the two wheels 15 straddle the row of growing cotton and when the lever 21 is adjusted properly the cuttingblades 20 cut out plants at intervals in the` row, While by adjusting the beams 28 the disks 29 throw the soil from each side to the growing plant.
