CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 317,400, dated May 5,1885.

Application filed August 4, 1884. (No model.)

To all whom it may concern:

Be it known that I, hIARK T. McGnn, a citizen of the United States, residing at Chipley, in the county of Harris and State of Georgia, have invented certain new and useful Improvements in Cultivators, of which the following is a description. i

This invention relates to that class of devices known as sulky-cultivators, in which a number of plows are attached to a frame mounted on wheels to be drawn by a team; and it has for its object to provide means whereby the sulky and the plows attached may be guided to run at an angle with or to one side of the path of the team drawing it, to assist in turning short corners, and in running close to fences, trees, &c. Its object is also to hang the plows so that the desired pitch may be given to each one independently of the other, and so that any plow may be held out of service, and so that the depth of plowing may be regulated either by hand or automatically.

To this end my invention consists in the construction and combination of parts hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is aside elevation of a sulky-plow according to my invention, the near wheel being removed. Fig. 2 is a plan view of the device, part broken away; and Fig. 3 is a front end view of the same.

A represents the wheels upon which the device is mounted.

B represents the side timbers of the frame, which timbers are set up endwise, and secured together by cross-ties G and D of iron. The ties G-one at the forward end, one at the middle, and one at the rear end of the frame lie across thetop,and are bent down the outside of the side timbers. The ties D are provided with T-heads at each end, which fit closely inside the side beams, and bolts 71, extending through these T-heads, thence through the timbers, and finally through the bent-down ends of the ties G, firmly secure the parts of the frame together.

E is a central longitudinal tic of iron,fir1nl y bolted to the cross-ties D.

The wheel-axle consists of two arms, 1 on which the wheels are journaled, bent upward at G on the inner faces of the side beams, 13,

and there secured by the bolts which pass through the central cross-tie, C, the side beams, B, and the parts G of the axle. By this means the axle is withheld from crossing the machine in line with its journals, thereby leaving room for the plow-beams H to be operated.

I is the tongue or team-pole, pivoted at its rear end directly in the center of the machine on a vertical pivot, which passes through the central cross-tie,(l, and the longitudinal tie E. The tongue is located between these two ties and between the forward ties, O and D, the

forward end of the tongue being free to oscillate from side to side, but held between the cross-ties vertically, so that the sulky may be tipped or held from tipping fore and aft thereby.

K is the crank-arn1 of a compound lever, of which L represents the working-arm in the form of two plow-handles pivoted along the tongue at M by means of. a portion of the le ver acting as a rock-shaft arm, and fulcrnmed to two eye-braces, N, which are loosely attached to the side timbers, B, but which hold the crank in a fixed position transversely relative to the frame, yet they allow the crank a slight endwise motion corresponding to the traverse of its pivot M in the arc of a circle. Supposing the point of the tongue to be fixed or to be carried inaline by the team, if the handles L be carried to the right the sulky-frame willbe turned to the right, and the wheels will run to the right out of the path of the team, and vice versa. Thus the driver, sitting on the sulky-sea-t O, i'nay guide the sulky to either the right or left of the path of the team, and he may thus greatly assist in .turning short corners.

P represents the plows, of which I have shown threeflhough any'snitable number may be used. Each plow is hung upon a two-armed iron hook or standard, Q, by means of a halt, R, which is pivoted at a, and provided with a series of holes, b, in the are of a circle concentric with its own pivot, through any one of which holes and through the arms Q a pin, 0, may be passed to fix the nlow at the desired pitch. he two arms of t e hook Q are hung upon the forward cross-tie, D, by means of two clips, S, which areclamped thereon and held by bolts above and below the cross-tie.

H is the plow-beam, pivoted at d between the arms of the hook Q, and supported at its rear end by a pair of arms, U, which are pivoted to clips S clamped on the rear cross-tie, D. The plows and plow-beams thus hung will swing forward and back sufficiently to entirely raise the plows out of the ground, and they may be held raised by means of the treadles V. A

Each of the treadles V is an extension beyond the hanging pivot of one of each pair of arms U, and serves as a lever, which, being pressed down, will raise and draw back the rear ends of the beam, thus drawing backward, raising the plows.

0 is a pin on each plow-beam to engage the treadle V to hold the plow raised in transportation or at any other time when the sulky i to move along without plowing.

f f are chains, attached at one end to the plow-beams and attachable at any point in their length to the hooks g,secured to the forward cross-tie, 1), whereby the plows may be prevented from entering the ground beyond a given depth.

The outside arms, U,and the outside hooks, Q, of each plow, except the center one, are

- larger than their mate arms and books of each plow, in order that the plows may be set sufficiently close together and yet have as broad a base of attachment to the sulky as possible.

The different hanging-hooks Q may be differently curved, to hang the plows one ahead of another.

Should it be desirable to control the depth of the plowing by hand, the rear arm, U, may be removed and the rear ends of the plowbeams T serve as handles to elevate or depress the plows.

By means of the clips clamping onto the cross-ties D the position of the plows may be and a. crank at the other end, and two bracerods loosely secured at one end and serving at the other end as a fulcrum to the compound lever, the crank being the pivotal connection at the fulcrum, substantially as shown and described.

2. The combination, with a frame mounted on wheels, of a plow, a hook or standard having two arms supporting the plow at their lower end, and spread apart and hung at their upper ends to the frame, a beam pivoted at some distance from its forward end between the two arms of the hook or standard, and a chain attached at one end to the forward end of the said beam and at the other end to the frame, as shown and described.

3. The combination, with a frame mounted on wheels, a plow,a two-armed hook or standard hanging the plow to the frame, a beam pivoted at some distance from its forward end between the hook-arms, and a chain hanging the forward end of the beam to the frame, of a pair of arms hanging the rear end of the beam to the frame, as shown and described.

4. The combination, with a frame mounted on wheels, a plow,'a hook hanging the plow to the frame, and a beam pivoted near its forward end to the hook or standard, of a pair of arms hanging the rear end of the beam to the frame, one of the said arms extended beyond the point of its attachment to the frame to Serve as a treadle for lifting the beam, and a pin in the beam for retaining the beam upon the treadle when lifted, as and for the purpose specified.
