SPECIFICATION forming part of Letters Patent No. 618,673, dated January 31, 1899.

Application filed December 17, 1897, Serial No. 662,265.

To all whom, it nwty concern:

Be it known that I, PI-IINEAS HERRICK, a citizen of the United States, residing at Elm, in the county of lVayne and State of Michigan, have invented certain new and useful Improvements in Cultivators, of which the following is a specification, reference being had therein to the accompanying drawings.

The object of the invention is to provide a cultivator which has all the desirable features, such as perfect lateral adjustment for the teeth, with simple means for raising and lowering the same without the use of any complicated machinery or special parts or castings but what canbe supplied or repaired by the farmer himself or the ordinary country blacksmith, an advantage which the manufacturer of agricultural implements at the present day is entirely losing sight of.

To this end my invention consists in the construction, arrangement, and combination of different parts,all as more fully hereinafter described, and pointed-out in the claims.

In the drawings, Figure 1 is a perspective view of my improved cultivator. Fig. 2 is a side elevation. Fig. 3 is a cross-section in the plane of the standards of the front wheels. Fig. 4 is a longitudinal section through front end of draft-beam.

A is the central draft-beam, provided at its front end with any suitable means for attaching the evener or whiffletree thereon, and B are the usual handles for guiding the cultivator.

C and D are front supporting-wheels, and E is a rear supporting-Wheel. The former are secured in the ends of an inverted-U- shaped frame formed of the standards G and cross-bar H, and the rear wheel is secured to a vertical standard I, the upper portion of which is curved forwardly. The standards G of the front wheels pass through vertical guide-bearings J, formed in the ends of a T- shaped cross -bar K, secured to the draftbeam by means of the bolt L and the U-bolt M, which at the same time secure the crossbars N to the draft-bar.

O and R are raising and lowering levers placed longitudinally and pivoted upon sup ports P and S on top of the draft-beam. The

inner adjacent ends of these levers are pivot- (No model.)

ally united by a bolt a, secured in one lever and passing through a slot Q in the other lever, and the outer remote ends of these levers are pivotally connected, respectively, to the center of the cross-bar H and the top of the standard I. I

T is a hand-lever for operating the lever B, and U is a notched segment with which a locking-latch Z) on the hand-lever is adapted to engage for locking the hand-lever adj ustably in position.

V are drag-bars, to which the cultivatorteeth TV are secured in any desired manner. The drag-bars V are arranged in two sets upon opposite sides of the draft-bar. Each set comprises three drag-bars formed of different length, the longest being on the outside and the shortest in the middle. forward ends of these drag-bars are formed with eyes 0, by means of which each bar is pivotally secured independently of every other by means of bolts or pins 01 between the cross-bars N, which are the necessary distance apart to receive the eyes between them.

X are outriggers, one for each set of dragbars. The inner ends of these outriggers are slotted and overlap each other, and a bolt 6 passes through the draft-beam and through these slots and thereby holds the outriggers independently adjustable in position. The outer ends of the outriggers are also slotted, and eyebolts f pass through these slots and adjustably connect the outer drag-bars of each set to the under side of the outrigger.

The middle drag-bar of each set is connected and adj ustably held in position between the .outer bars by means of slotted cross-bars Y, connecting the three bars of each set independently adjustably together by means of eyebolts g. Another short drag-bar V is directly secured to the draft-beam by means of the bolt L, passing through its forward end, and by the bolt M, which firmly clamps it between the cross-bars N, thereby spacing the latter the required distance apart and holding them more firmly in position by means of the bend it, formed in the bar V.

It will be seen that in my construction there are seven cultivator-teeth, each attached to an independent drag-bar and each independently adjustable and also independently ad- The.

justable in sets of three. The drag-bars forming each set diverge but slightly from the draft-bar and in their normal adjustment are substantially parallel to each other. This arrangement allows the use of comparatively light and springy drag-bars, and the connecting-bars X and Y may be adjusted forward or back, so as to give the bars more or less spring without altering the adjustment. The adjustments are all obtained in a simple manner without the use of complicated devices, and they provide for all contingencies which the nature of the soil or the state or style of cultivator may make desirable, at the same time as the cultivator has two front wheels well in advance and a rear wheel at the end of the draft-bar it runs very steady and makes the draft light enough for one horse. The device for raising and lowering is also very simple. It requires comparatively little force to raise the teeth out of the ground, as it provides for a vertical lift obtained by drawing the lever T rearwardlythat is, in a direction opposite to the draft-and the curving of the standard I makes the rear end, which is the heavier to lift, come up easy.

\Vhat I claim as my invention is- 1. In a cultivator, the combination of a central, longitudinal draft-beam, two sets of drag-bars carrying cultivator-teeth, each set comprising two long outer and one short central bar, a cross-head on the front end of the draft-beam to which the bars of each set are pivotally secured on opposite sides of the draft-beam, an outrigger for each set adj ustably secured at the inner end to the draftbeam and to which outrigger the outer bars of the set are laterally adj ustably connected, and a cross-bar to which all the bars of each set are independently adj ustably secured.

2. In a cultivator, the combination of a central longitudinal draft-beam, drag-bars having cultivator-teeth connected therewith, front supporting-wheels, a rear supportingwheel, standards by which said wheels are carried, bearings carried by the beam in which said standards are vertically adj ustable, a lever pivoted to the draft-beam and extending longitudinally thereof and connected at its outer end to the front-Wheel standards, a three-arm lever pivoted on the draft-beam and having one arm connected to the rear-wheel standard, the second arm slidably connected to the adjacent end of the first-mentioned lever, and the third arm of the lever constituting an operating-handle, and means for holding said three-arm lever in adjusted positions.

3. In a cultivator, the combination of the central draft-beam A, the drag-bars V, each carrying a cultivator-tooth and arranged in two connected sets on opposite sides of the draft-beam, the cross-bars N forming a twopart cross-head to which the drag-bars are independently pivoted, the slotted Outriggers X having overlapping inner ends connected by adjusting-bolts to the draft beam and to the drag-bars and the cross-bars Y.

4. In a cultivator, the combination of a central longitudinal draft-beam,two sets of dragbars carrying cultivator-teeth, each set comprising a plurality of drag-bars, a cross-head on the front portion of the draft-beam to which each of said sets of drag-bars is pivotally secured, an outrigger for each set of bars adjustably secured to the draft-beam and also adjustably secured to the drag-bars, and a cross-bar for each set of drag-bars,each crossbar having an adjustable connection with the individual bars of the set.

5. In a cultivator, the combination of a central longitudinal draft-beam, drag-bars having cultivator-teeth connected therewith, two front supporting-Wheels, standards for said wheels connected at their tops by a cross-bar, a rear supporting-wheel, a standard therefor, vertical bearings carried by the draft-beam in which said standards are vertically adjustable, a lever pivotally secured to the draftbeam and extending longitudinally thereof and connected at its outer end to the said crossbar, a three-arm lever pivoted to the draftbeam, one arm of said lever having a sliding connection with the adjacent end of the firstmentioned lever, the second arm connected to the rear standard, and the third arm constituting an operating-handle, and means for holding said three-arm lever in adjusted positions.

In testimony whereof I affix my signature in presence of two witnesses.

PHINEAS HERRICK.
