IMPROVEMENT IN CULTIVATORS.

The Schedule referred to :ln these Letters Patent and making part of the same.

To all 4whom it may concern.:

Be it known that LWILLIAM SNooK, of Nine Eagles, in the county of Decatur, and State of Iowa, 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 drawings, forming part of this speciication.

This invention relates to improvements in cultivators, designed more especially for cultivating corn, and adapted for cultivating on each side of a row simultaneously, and'to be operated by two horses.

The invention consists in improvements in the arrangements of the cultivator-attathments and elevating-devices to the frame, as will be hereinafter more fully specified. l l

Figure 1 represents a. longitudinal sectional elevation of my improved cultivator, and

Figure 2 represents a plan view of the same.

Similar letters of reference indicate corresponding parts.

The two intermediate cultivators A are required to be capable of being moved freely laterally by the feet of the operator, which are placed on the Shanks B.`

They are therefore suspended at the front ends Aof .their beams D, from the front beam of the flaming, by vhooking into rings or eye-plates, rigidly xed to the said front beam, as' shown at E.

These joints are also so formed that they serve to control the front ends of the beams when the cultivators are raised Vout of the ground.

The outer cultivators, G, are required to be under more control laterally, and they are therefore secured, by pivot-bolts H, to the sides of the bent plates I, in such a manner as to permit free vibration vertically, but in a limited degree laterally.

For raising the enltivators out of the ground, Iprovide a bent yoke, K, the legs L of which are pivoted to the flaming, near the rear, while the transverse Y part Vbetween the legs traverses the framing near the front;

The interior cultivator-beams are suspended bythe rods M from the said transverse part, and the outer cultivator-beams are suspended, by rods N, from the legs L of the yoke.

. For raising the. yoke and the cnltivators, I provide the-bent lever O, supported in bearings P on the axle, and connected to the yoke by a link, Q.

Having thus described my invention,

I claim as new, and desire to secure by Letters p IPatent-- The combination of the bent yoke K L, bent lever O, curved plates I, and the adjustable connecting-bars M N ofthe cultivatorLbealns, arranged, in the irrelation to the plows, as herein set forth.

.'lhe above specification of my invention signed by me, this 27th day of January, 1869.
