UNITED STATES orrrrcn JAMES A. KING, OF THREE RIVERS, MICHIGAN, ASSIGNOR OF TWO-THIRDS TO ISAAC SPAULDING AND ARTILLUS H. BANKER, OF THREE RIVERS, MICHIGAN.

CULTIVA'IOR.

Application filed April 23,

To all whom it may concern:

Be it known that I, JAMES A. KING, a citizen of the United States, residing at Three Rivers, county of St. Joseph, State of Michigan, have invented certain new and useful Im rovements in Cultivators, of which the fol owing is a specification.

This invention relates to improvements in cultivators. I have illustrated the same herein adapted as a cultivator for beets and like roots, although it is evident that it is adapted for use in various relations.

The objects of this invention are, first, to provide an improved cultivator which is soils in varying conditions, to substantially the same depth without adjusting the cultivator for soil or condition. Second, to provide an improved cultivator in which the draft of the cultivator tends to force the teeth into the ground that is, when the ground is hard, more power is required to draw the cultivator, and this increased power adds increased pressure to the teeth or shovels to force them into the ground. Third, to provide an improved cultivator embodying the above advantages which is simple and economical in structure and strong and durable.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing forming a part of this speciication, in which- Figure 1 is a perspective view of a struc ture embodying the features of my invention. Fig. 2 is an enlarged detail showing the coupling or connection for the thills or shafts to the brace arms a a of the shafts to the bars a. Fig. 3 is a detail vertical section showing the hinge or pivoted coupling for the forward ends of the bars B to the axle. Fig. 4 is a detail vertical section showing the hinge or ivoted connection from-the rear ends of the bars B to the tooth carrying frame. Fig. 5 is a detail side elevation showing the relation of the shaft bars a with the tooth-carrying bars or links B and the thills, the movement of the parts being indicated by dotted lines.

Specification of Letters Patent.

1906. Serial No. 313,263.

Referring to the drawing, A is the axle and A the carrying wheels. On the axle A are mounted brackets A. To these brackets are rigidly secured downwardly and forwardly projecting draft bars a. On the brackets A are upwardly projecting hinge members A. The bars or links B are secured to the brackets A by the vertical pivots b, which are arranged through suitable ears on the hinged members B to which the bars B are rigidly bolted. This permits the lateral swinging of the bars B, but prevents the vertical swing thereof relative to the brackets A.

On the rear end of the bars B is secured the beam or frame O. The teeth or shovelstandards C are adjustably secured to the frame 0 by means of bolts 0 which are arranged through suitable longitudinal slots 0 in the standards. By this means the vertical position of the teeth may be adjusted.

On the lower ends of the standards are suitable shovels or teeth C, which may of course be of any form desired, those I have illustrated being especially designed for the cultivation of beets or like roots.

The frame O is pivotally connected to the l B and the vertically arranged hinge pivots j b. The operating handles I) are secured to i the bars or links B. By this arrangement l the teeth carrying frame C may be swung j laterally. By pivoting the frame C to the l bars B the cultivator teeth or shovels maintain their proper positionthat is, their posi tion relative to the draft is not affected by the swinging of the frame.

The thills or shafts E are connected by the downwardly projecting brace arms a a to the forward ends of the bars a by the bolts a. The arms a a are pivotally connected to the draft bars a, the lower ends of a pair of arms being arranged on each side of the draft bars and properly spaced to permit ivotal movement by means of the sleeves a on the bolts ct of the draft bars.

To assist in securing any depth of cultivation I provide a spring counterbalance for the teeth. This consists preferably of an arm F projecting upwardly and rearwardly from the axle. As the brackets A are secured to the axle, when the axle is rocked it acts upon the brackets.

The arm F is connected to an arm G on the cross-bar E of the shafts by means of the links 9 andf and the spring I. The link rear ends of the bars B by hinge members f is connected to the arm F and to one end of the spring I, and the link is connected to the arm G and to theother end-of the spring I. The link 9 is threaded, and the hand-nut g is provided therefor, whereby the tension of the spring I may be regulated.

With the parts thus arranged, the draft or reduced, thereby allowing more of the weight of the cultivator to be carried by the wheels, so that the ground is cultivated to an even depth without any adjustment of the cultivator. That is, of course, a very great advantage.

hinging the teeth carrying frame C to the rear ends of the bars thesame may be easily swung from side to side to follow the row, and no matter in what positionthe teeth always maintain their properrelation to the line of draft.

In transporting the cultivator from field to field the bars B are elevated until the loops is may be engaged on the hooks K which are carried by the rearcross-piece E of the thills or shafts.

The counterbalance spring I prevents the teeth running deeper than is desired. By means of the adjustment of the spring the same can be set'as conditions may require. In the drawing the structure is illustrated with the teeth entirely out of the ground, so thatthere is no pull upon the spring.

My improved cultivator is very easy to manipulate and the teeth are very easily guided. I have illustrated and described the same in detail in. the form preferred by me on account of convenience in operation and manufacture; I am, however, aware that it is capable of very great variation in structuraldetails without departing from my invention.

I-Ia'vingthus described my invention, what I claim as new, and desire to secure by Letters Patent, is
