COTTON CULTIVATOR AND THINNER SPECIFICATION forming part of Letters'Patent No. 450,303, dated April 14, 1891.

Application filed August 2, 1890.

same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. a;

My invention relates to a combined cotton chopper and cultivator, the object of the same being toprovide a machine that will cultivate the plants, clean the weeds from between the rows of plants, throw fresh-dirt up around the same, and thin them out, bringing the plants to a stanc This machine may be used to cultivate and thin out any plants planted in drills or rows and requiring to be brought to a stand.

\Vith these ends in view my invention consists in the parts and combination of parts, as will be fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of my machine. Fig.2 is a longitudinal vertical central section through the same. Fig. 3 is a detail perspective View showing the spring-catch lever located on the axle. Fig. at is a perspective view of the notched head of the cultivator-beams. Fig. 5 is a perspective view of the clip to which the thinneror chopping arm is pivoted. Fig. 6 is asimilar view of the chopping-blade provided with a slot. Fig. 7 is a perspective view of aslight modification of means for pivoting the chopper-arm to the cultivator-beams.

A represents the axle of the machine, and a a the wh eels on which the machine runs. The wheel a is provided with a ring having cams on its outer surface. a and a are hangers suitably secured to axle A, on which are pivoted the cultivator-beams B and B by means of the plate a Thelower ends of these beams are secured together by means of a plate B Secured to the beams B and B, respectively, are shovels b b and cutters b b. The upper ends of said beams are secured together by Serial No. 360,762. (No model.)

means of a slotted or notched plate N, which engages With a lever c, which is pivoted in plates 0 O and works between guides secured to the axle. This lever c is provided with a notch c and a lug or projection 0 said lug serving to limit, when desired, the upward movement of the beams B and B.

c is asuitable spring secured to the axle and presses against the curved lever or arm 0. is a suitable handle secured to lever or arm 0.

D is the chopper-arm, which is pivoted to the cultivator-beams by means of the plate (I. Secured to the lower end of the arm D by means of screw or bolt (1 is an adjustable chopping-blade D, having an elongated slot 4 C1 The upper end of the arm D is angular and bounded or faced with metal or other suitable material (1. Said plate (Z is provided with a lug or projection (1 which engages a right-angle plate cl, secured to the axle.

(Z is a flat orother spring, which is secured to hanger a and engages the chopper-arm D.

d is a ring secured in the said arm.

E is a guide secured to the beam B, having a depending end 6, said guide serving to limit the upward and outward motion of the chopper-arm.

I) is a handle or lever secured to the beam BI The operation is as follows: The machine being in operative position, as shown in Fig.

1, it is placed at the beginning of a row and started forward, the angular end of the chopping-arm engagingthecam-ringa Theknives I) out the row out from the sides of the plants, and the chopper-blade D cuts the weeds, &c., from between the plants designed for the hill or stand. The shovels h, following, throw the soil up around the plants. It will be seen that the row will be chopped to a stand and dirted on both sides at a single passage of the machine along said row. here it. is desired to throw the beams 13 and B out of a directline with the wheels at and a, the lever o is drawn forward by means of the handle 0 the driver then throws the beams to either side by means of lever b, and the lever c is then let go and it engages one of the side notches in the.

notched plate 19 The chopper-arm, when it is desired, is thrown out of engagement with the cams on wheel a by placing the pro- ICC jection (l in engagement with d. In moving the machine from one place to another it is always desirable to raise the shovels and blades from contact with the ground. To effect this raising I simply pull the lever 0 forward until it is out of engagement with the notched plate b and force the beams down by means of lever 1) until the notched plate 11 comes into engagement with the notch c in lever c.

WVhat I claim, and desire to secure by Letters Patent, is.-

1. A cotton-cultivator consisting of the beams pivoted on suitable hangers secured to the axle, cutting-blades and shovels secured, respectively, to the beams, and a notched plate connecting the upper ends of the beams, in combination with a notched lever secured to the axle and lever 17, all constructed and operating substantially as described.

2. In combination with a cultivator, substantially as herein shown, a ring composed of a series of cams secured to the inside of one of the wheels of the cultivator, a chopperarm D, pivoted to said cultivator and engaging said cam-ring, the adjustable choppingblade, and the spring (Z and catch (1 all combined and operating substantially as described.

3. The combination, with a cultivator having beams 13 and B, of a notched plate 39 securing said beams together, and a curved lever 0, pivoted, as described, and provided with notches and a lug, spring 0", and guideways 0 all substantially as described.

I. A combined cotton chopper and cultivator, consisting of the beams B and B, pivotally secured by meams of plate a 0n hangers and provided with cutting-blades b b and shovels b b and a notched plate W, a curved lever or arm 0, provided with notches and a projection, said lever or arm working in guideways 0 and engaging the notched plate 19 spring 0, chopper-arm pivoted to the beam 13 and provided with an adjustable choppingblade D at one end, and an angular portion at the other end and a lug cZ a catch (1 and a cam-ring which is engaged by and operates the chopper-arm, spring (1 and guide E, all constructed and operating substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
