- Specification forming part of Letters Patent No. 37,166, dated December 16, 186.2; Reissue No. 7,944, dated November 13, 1877; application filed June 25, 1877. v

To all whom 'it may concern:

Beit known that I, HENRY I. HEATON, of Sidney, in the county of Fremont 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 of the same, reference being had to the accompanying drawings, making a part of this specification, in Which- Figure l is a side sectional View of my invention, taken on the linea' Fig. 2. Fig. 2 is a plan or top view of the same.

Similar letters of reference indicate correspending parts in thetwo igures.

This invention relates to an improved cultivator of that class in which adjustable or latverally-slidjn g shares or teeth are employed.

To enable those skilled in the art to fully.

understand and construct my invention,-I will y proceed to describe it.

on the frame in a transverse direction therewith, said bars being fitted in suitable guides d on the frame A.

D represents the draft-pole of the machine, which is attached by a pivot-bolt, d, to the front part of abar, E, said `bar projecting centrally from thel front part of the frame A. The draft-pole D extends to the back part of the frame A, and is connected at e to the sliding bar C', which is on the back part ofthe frame A. The sliding vbar C, which is on the front part of said frame, has an upright bailshaped support, f, attached to it, to which a lever, F, is attached, the front end of said lever being secured by a staple, g, to the draftpole D, which staple forms a fulcrum for said lever. The front sliding bar C is also connected by an arm, G, to the draft-pole D, the front end of said arm being attached by a pivot, h, to the center of bar C, and its back end connected by a pivot, t', tothe transverse bar b', the arm G being connected to the draftpole `D by a pivot, j, at a pointabout'midway between the bar O and the Vtransverse bar b'. (See Fig. l.)

From the above description it will be seen that by moving the lever F either tothe right or left, the bars C C will be simultaneously moved in the same direction, and also the back part of the draft-pole D, the front part of the latter being .held by the neck-yoke and team. Each sliding bar -C C has two pendent bars, H, attached to it by screw-bolts k, which pass through oblong slots l in the bars C C', and are secured therein at any desired point by the nuts m of the bolts. attaching the bars H to the bars C C', the former may be adjusted laterally at a greater or less distance, as desired. y

I I represent inclined braces, which are attached at their front ends to the lower parts of the pendent bars H of the front bar C, and

` attached at their back ends to the upperl part -of the bars H of the back bar 0'..

J J represent narrow frames, formed, each, of two parallel bars, n n, connected by transverse bars o. The front ends of these frames are connected by joints p to the lower ends of the pendent bars H of the front sliding bar C. The

back parts of these frames J are connected by chains q to a shaft, K, the journals of which .are in inclined bars L L on the frame A, on

the back parts of which the drivers seat M is secured. The shaft K has alever N, attached to it, and a. hook, o, is attached to hold the lever N, when pressed down. The pendent y bars H of the back sliding bar C t in the back parts of the frame J J, and serve as guides for the same, preventing any lateral working or play thereof, independent of the sliding bars C C.

To the frames J J the shares or teeth P are attached. These shares or teeth may be of the usual or any proper form, and they may be By this mode of *A moving in arreverse direction tothe shares or teeth, and'consequently enabling the machine to be readily adjusted to the sinuosities of the rows or plants. The shares, it will be seen, may be adjusted nearer together or farther apart by adjustingthe pendent bars. H, `as Previously described. It is designed to have the shares of the two frames J J work at opposite sides of cach row of plants, a horse walk- Y ing'in the spaces between the rows.

The double-tree P is pivoted to the frame A, near its back part, and a draft-rod, Q, is attached to each end of 'ahw-doubletree. These rods extend forward on each side of the frame,

and are attached at their forward ends to pendants R, which are connected to the front transverse bar b by hinges or pivots, which admit of a forward and backward movement of the pendants to utilize the swinging movement of the double-tree as an 'evenen The whietrees are attached to the pendants R, which admit of the necessary play of the double-tree,

and serve to producel la low draft to balance A tached, all arranged as and for the purpose hereinbefore set forth.

2. The combination, with a double-tree pivoted in rear of the supporting-axle of the cultivator, of pendants located in advance of said axle, and rigid draft-rods directly connecting the outer ends of the double-tree with the lower nds of said pendants, substantially as described.
