COMBINED CULTIVATOR AND SEEDER.

SPECIFICATION forming part of Letters Patent No. 435,831, dated September 2, 1890.

Application filed March 1, 1890.

T0 ctZZ 10710712 it may concern.-

Be it known that 1, JAMES S. I-IIOKMAN, of Hickmamin the county of Iroquois and State of Illinois, have invented certain new and useful Improvements in Combined Seeders and Cultivators, of which the following is a specifieation.

My invention relates to cultivators in which a series of cultivators arranged in gangs are employed; and it consists in certain novel features of construction and peculiar combination of parts, all of which will hereinafter be fully described in the annexed specification, and particularly pointed out in the claims, reference being had to the accompa; nying drawings, in which- Figure l is a top plan view of my improved cultivator and seeder. Fig. 2 is a rear view thereof. Fig. 3 is a longitudinal vertical section of the same on the line 3 3, Fig. 1. Fig. 4 is a perspective view of the overhung frame. Figs. 5 and 6 are detail views, hereinafter referred to.

In the accompanying drawings, A indicates the main axle, which is formed with a desired number of arched yokes a a, usually four in number, being arranged for eight gangs of cultivators, on the outer ends of which are mounted the supporting-wheels B B.

To hold the axle A from sagging, I secure it to a frame-work (l,which consists of a rear crossbar c,-the forwardly-prejecting tongues c c, the cross-piece c'-, and the intermediate bracebars c 0 the axle being secured to the rear cross-bar c, as shown. To more securely hold said axle and the frame (1 in rigid connection, I provide a series of truss-rods D D, connected at one end to the forward part of the frame C and at the rear end to the arched axle A.

The overhung cultivator-frame E consists of the rearwardly-extending arched bars F, the rear ends F of said bars extending vertically downward and connected to the supporting-frames G G, which carry the trailing or supporting wheels II II in their bifurcated rear ends.

J denotes a rod, which forms a support for the eultivato1-frame,held to slide in elongated slots 6 '11, formed in vertical guides I Lseeured upon the forward ends of the frames G G, said Serial No. 342,307. (No model.)

cultivator-frames being secured thereto in a manner most clearly shown in Fig. 2 of the drawings, by reference to which it will be seen that I arrange the cultivators in gangs, two in each gal'lg and one gang for each row to be cultivated.

K denotes the cultivator-beams, which are preferably formed of spring-arms, pivotally connected at their front ends to the arched axle, their rear ends being bent down to form the standards for thecultivator-shovels, which may be of any desired construction and attached thereto in any well-known manner.

Upon the beams K are held to slide adjustable blocks L. Bythelongitudinal movement thereof on said beams the cultivatorshovels may be adjusted to or from each other, said blocks being held in position by the set-screws Z Z.

The gangs of cultivators are connected with each other by means of arched yoke-bars M, the ends of which are connected to the outer blocks L, their upper portion being formed with loops m, which engage loops or eyes a, formed on the cross-bar J, as shown.

Each set. of cultivator beams is further supported by means of a flexible connection 0 to a cross-bar N, connected to the arms F and extending nearly over the shaft J, such bar forming a tramway for the double pulleys 0 on the ends of the connection 0, whereby a free lateral movement of the .cultivators is permitted when moved sidewise, with the balance of the overhung frame, and also admitting of a limited lateral movement of the bar J and the cultivator-s irrespective of such movement of the arms F F.

To permit of the last movement referred to, it will be seen that I arrange the bar J not only for free vertical movement, but also for limited lateral mo ement in the said bearings I, and I provide said bar with loops j j, through which pass the rods P P, pivoted at their forward ends to the cross-bar o. By this construction increased leverage is obtained for guiding the gangs laterally, said rods P being held in suitable eyes or loopsj, whereby to lift the gangs out of the ground when turning the machine.

At each end of the bar 0 is arranged a pulley-support, over which pass chains Q Q, connected at one end to the frame 0, and at their outer ends to the overhanging frame E in such a manner that the weight of said frames may be nearly balanced, leaving only enough pressure on the rear end to press the crazy wheels or runners on the ground to assist in guiding the machine. By thus connecting the frames E and C it will be seen that a rocking motion for the cultivator-frames is obtained.

One set of operating -levers is employed for each gang of plows or row to be cultivated, said levers being attached to the axle-bar c, as shown, one of said levers S'connnected to the arches, the others direct to the cultivatorframes, by means of which the operator may guide the cultivators, and, if desired, elevate any one of the gangs, or one of the cultivatorframes of each gang, as he may desire.

By my arrangement of cultivators it will be seen that the operator can cultivate four,-

practically one gang so far as being moved to right or left, thus enabling the operator by holding on one row to hold on all. While these gangs are rigid so far as moving to right across as well as the way the seed was planted or dropped.

It is obvious that suitably-arranged seedboxes may be secured upon the axle, which may be divided into a series of compartments to receive difierent kindsof seed, and such compartments may be provided with any of The crazy or supporting wheel arrangement is so connected to the guide-rods that when these guide-rods are moved'to right or left, as may be desired in cultivating, it throws the crazy-wheels awry, (or sidewise,) and then by the forward motion of the team the entire gangs of cult-ivators are thrown to right or left at will of operator. The front parts of the crazy-wheel frames have perpendicular elongated slots for cross-rods to assist in throwing crazy-wheels awry.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is V 1. An improved cultivator, seeder, and dropper, consisting of the main axle, asup porting-frame C, fixedly held thereon,and an overhung rearwardlyextending frame E, held to said frame C, adapt-ed for'ver-tical and lateral movement, said frame E provided with the crazy-wheels H H and adapted to support the cultivator-gangs, substantially as'and for the purpose described.

2. An improved cultivator, seeder, and dropper, consisting of the main axle, the supporting-wheels, said ,ax-leformed with aseri'es of arches, a frame 0, mounted on and braced to said axle, a rearwardly-extendingframe E, hung to said frameO, and the cultivator-gangs supported at the rear portions onsaid frame E and having a pivotal connection with the arched axle attheir forward ends, substantially as shown and described.

3. The combination,with the frame C,fixedly held at its rear end upon the axle and pro- .vided at said end with the double guidepulleys, ofthe overhung frame 'E, provided vided with a series of arches, the frame G held thereon, and the truss-rods D, connected thereto and to the frame O, of the overhung frame E, consisting of the side bars F F, pivoted at their forward ends to the frame 0, their rear ends extended downward, the frames G G, secured to the said lower-ends, the supporting or crazy wheels H H, mounted thereon, said frames provided with vertical slots at the forward end, the cross-bar J held for vertical and lateral adjustment therein, and the cultivator-gangs supported at their rear ends on the rod J, their forward ends pi-votally held on the main axle, substantially as and for the purpose described.

5. The combination, with the main axle and the frame 0 held thereon, of the frame -E, consisting of the arms F,..pivoted to the frame C and carrying the frames G, provided with the supporting or crazy wheels H, the cross-bar J, held on said frames G, the cross-rod N,

connected to the bars F F, forming a tra1n- Way, the cultivator-frames connected to the bars J, and the flexible connection between said cultivator and tramway, said cultivators 7 having a pivotal connection at their front ends to the main axle, all arranged substantially as and for the purpose described.

6. The combination, with the main axle provided with a series of arches, the frame 0, fixedly held thereon, the bars F F, pivotally secured at their front ends to the frame 0, the frames G, and the Wheels H, held to the bars F, said frames G provided with slotted standards I I, and the cross-bar J, mounted in said slotted standard, of the cultivator-frames arranged in a series of gangs, each ganghaving a yoked connection M with each other, said yokes connected to said cross-bar J, said cultivator-frames hung at their forward ends to the arched axle, substantially as and for the purpose described.
