Specification forming part of Letters Patent No. 120,684, dated November '7, 1871.

To all whom it may concern:

Be it known that I, JEROME H. ToMLnvsoN, of Mount Carroll, in the county of Carroll and State of Illinois, have invented a new and Improved Cultivator; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specilication.

Figure l represents a plan or top view, partly in section, of my improved plow. Fig. 2 is a longitudinal vertical section of the same on the line c c of Fig. l. Fig. 3 is a detail transverse section of the same on the line K K, Fig. l.

Similarletters of reference indicate corresponding parts.

The object of this invention is to so connect the plow-beams with the axle-bearings of the wheels that thelateral motion of the plows will be inversely followed by a similar twist of the wheels.

A in the drawing is the cross-bar of the frame, to which the pole or shaft B is rigidly secured. C C are the wheels, hung on pins or axles @that project from vertical posts B. These posts are swivel'ed in bearings d and e formed respectively on the under side of the cross-bar and on horizontal plates f, which are bolted to and under pendent frames D attached to the cross-bar. The wheels, being thus hung to the swivel-posts, can be swung to the right or left at will. E E are the plow-beams. Their front ends are hung to vertical swivel-posts g, which can turn in the frames D. Cranks h of the posts g are, by diagonal braces t' t', connected with a front yoke, F, whose ends are affixed to arms 7' projecting from the posts b. The posts b and g are thus connected to each other so that when the plows are swung to the right the wheels will also turn to the right, and vice versa.

The operator has complete power to govern the side movement of the forward as well as the hind end of the plows, and crooked rows can be plowed with greater ease than without this de vice. The plow requires less care in driving, for the wheels will adjust themselves to keep always in front of the plows. No up or down movement oi the plows, only their side movement, will affect the motion ofthe wheels. /Vhenever the team gets oi' the rows it is only necessary to swing the plows aside, whereby the wheels are set so as to affect the motion of lthe wheel.

I am aware that a patent has been granted for placing the wheels of a plow or cultivator in such relation to a hand-lever that the wheels and plowframe can be kept in the direction ofthe row and run out to the end thereof after the horse has turned; and I do not desire to make claim to any such device; but

What I do esteem as my invention, and desire to protect by Letters Patent, is-

A wheel-cultivator having the end-pivoted beams E E of the plows attached by the described connecting mechanism to the pivoted axles of wheels C C, as described, so that as the plowman moves the handles of his plows laterally both plows and wheels will correspondingly adapt themselves to the sinuosities of the rows and avoid cutting up the plants.
