CULTIVATO R.

SPECIFICATION forming part of Letters Patent No. 296,615, dated April 8, 1884.

Application filed November 18, 1882.

To all whom it may concern.-

Be it known that I, Cnaononv M. PINCK- NEY, a citizen of the United States, residing at Aledo, in the county of Mercer and State of Illinois, have invented certain new and useful Improvements in Cultivators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and tothe letters and figures of reference marked thereon, which form a part of this specification-- Figure 1 being a top View of the cultivator; Fig. 2, a vertical section in a plane indicated by the line a" m, Fig. 1; Fig. 3, a rear view of the frame of the cultivator, showing, also, the plow-beams in crosssection; and Figs. 4, 5, and 6, views of parts detached.

Like letters designate corresponding parts in all of the figures.

My invention belongs to the class of straddle-row wheel-cultivators, the main parts of which, as shown in the drawings, are the two supporting wheels A A; i the arched frame B,

. support-edby the axle-journals a a, on which the wheels turn; the two plows O O, pivoted to this frame behindthe same; the hounds D D,

mounted centrally on the top of the frame, and the tongue or pole E.

My improvements will herein be specified in succession.

My first improvement consists in a draft and weight equalizer constructed and operating as follows: From the fixed cross-beam G on the forward end of the hounds D D the draft-bars H H, to which the single-trees of the team are hitched, are suspended by pivots or free joints at b b, so, that their lower ends may move forward or backward; and upon the hounds D D, which extend backward of the frame B, and at a suitable distance behind the said frame, as indicated, is mounted by a fulcrum or pivot, c, a freely-tilting cross beam or lever l, so that its two ends may play up or down. Each draft-bar H is connected at its lower end by a rod, d, with the forward end of a bell-crank or swan-neck lever, J, pivoted to the frame 13, and extending both forward and backward therefrom, and having substantially the form (No model.)

shown, and indicated by its name; and with the rear end of each swan-neck lever is connected by a rod, 6, one end of the pivoted lever I, the two arms of which are equal in length. The effect of this construction is to cause the draft of the team to bear down on the lever I at both ends through theintermcdiate levers, J J, and consequently to depress the frame in the rear, and thereby to counterbalance the weight of the tongue or pole and properly balance the whole weight and draft of the cultivator, so that it shall be easy to the horses, as well as effective in action. The pivoting of the crosslever I tends to equalize and properly distribute the draft of the two horses when one draws more forcibly at times than the other. Iprovide suitable means for adjusting the length of the tongue or pole to suit the size of the horses employed to draw the cultivator or to determine their distance from the draft-bars, as may be desired. I accomplish this by adjusting the tongue E forward or backward between the hounds D D, which is effected by incasing the rear end of the tongue between the hounds and suitable cross-bars, ff, (together with the crossbcam G as one, if desired,) so that it will be held closely in the right position thereby, with freedom to slide back and forward, and by providing the tongue with aset of holes, 9 g, Figs. 2 and 4, through either one of which to suit the purpose a bolt, h, is passed, and through one pair of holes in the hounds.

My next improvement consists in the means of connecting the plows G O with the frame B, by which the distance of the forward end of the plow-beams from the row of corn or other plants and the height of the same from the ground are adjusted, while the free lateral and vertical swinging movements are allowed to the plows. The forward ends of the beams i z of the plows are pivoted byhorizontal pivots j j to rock shafts or bars K K, there being sets of holes k k in thesaid rock-shafts for receiving the said pivots at different heights, and these rock-shafts are journaled in bearings L L, having slots Z Z, through which the bolts m m, that attach them to the frame B, pass, and allow the lateral adjustment of the bearings. Thus the two adjustments of the plows are effected.

' preferably attached to pieces or plates 01. a,

which are hinged to the upper ends of the arms M M, to allow a freer and easier connection between the chain and arms. This connection, being thus raised to about the height I 5 of the handles 0 o of the plows, rendersthe control of the plows more easy and sure. The shovels or workingpoints of the plows, being always set to throw the earth toward the corn, assist this construction of the plow-connection in keeping the plows steady. I provide frangible pins for allowing the plow-points to #yield without injuring the plow when an unyielding obstruction is encountered thereby. This arrangement is to place them near the middle of the brace-bars O O, which hold the plow-points in position. The pins p p are put through holes in the two parts of the bracebar, which may be as sharp as desired. The connection is made here more readily, easily,

, and securely than when the connection is made at either end; and the separated parts of the bar, being short and each held securely at one end, are not so liable to be injured or do damage as by the old construction. One part of 5 the bar is best made double, and the other part arranged between the sides of the double part, as shown in Fig. 5. Iapply plant-guard P on the inside of each plow. It is made with open slots, or of skeleton construction, as 0 shown in Fig. 2. Its two arms, q q, for attaching it respectively to the forward and rear parts of the beam, are provided with slots M", to receive the attaching-bolts s 8, whereby the guard maybe adjusted to different heights, as

5 desired.

My next improvement consists in the pecusoil, and easier to control the depth of cutting liar form of the shovels Q Q, as shown in Figs. 1 and 6. The forward point, t, of each shovel, instead of being central between the side edges, is much nearer the outer edge than the inner, substantially as shown, and the shovels are curved concavely in mold-board form, the concavity being substantially parallel with the inner front edge, a, of the shovel. This form gives a better front edge for searifying the by, and throws more earth inward toward the plants, and that more freely than any other form with which I am acquainted.

I disclaim an adjustable evener for cultivators such as described in 'Letters Patent No. 129,420, which also has a bell-crank connection between the evener and the draft. In the said patent no pivoted draft-hangers are shown, whereas my construction of the evener back of the axle, in connection with the pivoted draft-hangers in front of the axle, more fully regulates the balancing of thetongue.

WVhat I claim as my invention, and desire to secure by Letters Patent, is

1. In a draft and weight equalizer for cultivators, the combination of the suspended draft-bars H H, situated forward of the axle of the machine, vertically-swinging cross-lever I, situated back of the axle, bell-crank 75 levers J J, horizontal rods dd, connecting the said hanging bars and the bell-crank levers, and vertical rods 6 6, connecting the cross-lever with the bell-crank levers, substantially as and for the purpose herein specified.

2. The combination of the plows O 0, rockshafts K K, provided with adjusting pivotholes is k, bearings L L, provided with adjusting-slots Z Z, and bolts m m, with arched frame B, substantially as and for the purpose herein 8 5 specified.

Intestimony whereof I affix my signature in presence of two witnesses.
