192,541, dated June 26, 1877; application filed J anuary 22, 1875.

To all whom it may concern:

Be it known that I, GARRY STORM, of Portland, in the county of Ionia and State of Michigan, have invented an Improvement in Gultivators, of which the following is a specification:

My invention relates to a two-wheeled cultivator; and consists in the combination of the parts for raising, lowering, and locking the shovel-beam,the peculiar features of which are the curved links, which allow the rockshaft to be thrown beyond the center, looking it in that position when the shovels'are either in or out of the ground.

Figure 1 is a perspective View of the implement, showing the cultivator-frame lowered. Fig. 2 is a longitudinal vertical sectionat a: w, showing the cultivator-frame raised.

In the drawing, A A represent two traction-wheels, each mounted on an axle-arm, B, bolted under the end of an axle-bar, G. The arms B are dropped, to give the axle-bar the required elevation. D is the pole, bolted across the top of the axle-bar, as are also two diagonal braces, D. To the under side of the pole and braces a transverse bar, E, is bolted, and between it and the axle-bar a second one, E. is in like manner bolted. F F F are the cultivator-bee ms, to each of which two shovelstandards, G, are bolted on opposite sides. The front end of each beam F carries a clevis, a, formed of two straps, fastened by horizontal through-bolts, which clevis embraces the lower part of a hanger, b, pendant from the bar E. The hanger has a row of holes, through one of which'the bolt which pivots the clevis to it passes, thereby adjusting the pitch of the beam. Above the holes a brace-rod, 0, extends from each hanger back to the axle-bar. The whiffletrees of the team are engaged with a hook, pivoted in the clevis of the middle beam, whose clevis is elongated to receive it. H is a rock-shaft, journaled across the rear end of the pole, in brackets I, projecting from the axle-bar. At its end is a lever, J, within easy reach of the driver from his seat K. On the rock-shaft are two arms, d, each perforated with several bolt-holes, to receive a pin or bolt at the upper end of a curved link, L, whose lower end is pivoted in the upseveral cultivator-beams. The top end of each llnk has several bolt-holes in it, through any of which the bolt which pivots it to the arm may be passed, to regulate the drop of the rear ends of the beams, while, by rotating the high enough for the shovels to clear the ground.

The links being curved, the arms may be thrown back of the upper center, and thus lock the shovel-beams in theirelevated position.

The shovels are lowered by throwing forward therock-shaft lever until the arms are There being no mortises and tenons, as all the parts are bolted together, repairs can be made by the farmer with simple tools.

By means of adjustment at both ends of the cultivator frame-work the beams can always be kept level while working at different depths.

The means for raising and lowering the shovel-beam and locking the same in either position are simple, efficient, and much less complicated and expensive than many in use.

per side of a bar, F, bolted to the tops of therock-shaft backward, the beams may be raised arrested by stops e on the sides of the brackets.
