To all whom it may concern?? Be it known thatlfHENRYE.: CARVER, of

Marion, in the county of Linn, and State of `Iowa, have invented certain new'and useful Similar letters of reference indicate corre-` sponding parts in all the figures.v1

This invention relates to sulky attachments for plows; and it consists in the construction of aframe having downward-projecting brackets for carrying the adjustable stub-axles, by which the lateral pitch of the plowr may be regulated, all as hereinafter more fully set forth.

I shall now proceed to describe the construction and operation of my improved, plow attachment, reference being had to the drawings hereto attached.

A is the plow, the detailed construction of which is immaterial, as any suitable plow may be used in combination with my attachment. A1 is vthe plow-beam, and a is the clevis atthe end of plowbeam. B denotes the frame of my attachment, which consists of four beams, represented by B1, B2, B3, and B4, united by cross-pieces B5 B6. C is the tongue, which is firmly bolted,-or otherwise secured, onto the cross-pieces B5B6, as shown.

To the front part of the tongue, within the frame, is secured a segmental ratchet, l), within the center of which is pivoted a bent lever,E. Lever E is easily operated from the drivers seat by a handle, El, having a spring catch or pawl, e, or equivalent device, by which the lever may be secured in any given' position lrpon the ratchet D. To the end of the short bent arm E2 oi' lever E is pivoted a rod, b, the other end ot' which is pivoted to the clevis a of the plow-beam A1.

`F1 F2- and F3 F4 are strong iron arms or brackets bolted onto the beams B1 B2 and Ba 'brackets F2 and F3.

B4 respectively, as shown in the drawing. The lower ends of these brackets form journals or bearings, f, for shafts'Grl G2, secured upon which are the bent stub-axles H1 H2. The

-wlleels I are secured upon these axles in the usual manner. To the ends of the shafts G1 G2 are rigidly secured two levers, K1 K2, (one to each,) so that, by turning these levers, the shafts, and with them the stubaxles, will be turned. The levers Kl K2 may be retained in any given position by means of pins c secured upon the beams B2 and B3, or by equivalent devices. The levers K1 K2 are affixed upon the shafts G1G2 in such a manner'that, when one of said levers (K2 in the drawing) is in a vertical or upright position, and the other (K1) in its lowerlnost position, or resting upon the front crosspiece B5, the position of the stub-axles, which are operated by these levers, will be such, in their relation to each other, that one (H2 in the drawing) is raised up, and the other (H1) is depressed. As these axles move in a circle around their respective shafts, it is obvious that their elevation may be readily controlled and adjusted by their respective operating-levers in such a manner that they, with the wheels aixed upon them, may be either on a line, or either side may be raised or lowered at the pleasure of the driver, who operates the levers K1 and K2 from his seat. By this arrangement, one side of my sulky attachment may be raised, and the oth'er lowered, or vice versa, in passing over hill-sides or slanting ground, so that the plow will be kept in its perpendicular position,'and make a straight up-and-down furrow.

Afxed to the rear part of the machine is a stout bail or projecting double-bent arm, denoted by L, which'is pivoted in bearings upon the back part of the downward-projecting This bail may be raised or lowered by means of a rod, d, that is pivoted at one end to a short lever-arm, g, rigidly secured to one end of bail- L, and at the other to a lever, M, which has itsfulcrum at h, and is so placed that it may be readily operated from the drivers seat. When leverM is pulled toward the rear of the machine, the bail L is raised, and the rear part of the plow being secured to this bail by a chain or other suitable means, it follows that the plow is lifted out of the ground. When, on the other hand, lever M is pushed forward, the bail, and with it the plow, is lowered.

I am aware that it is not new to provide means for adjusting the lateral pitch of ridin gplows, or for elevatingthe plow or plows above the soil; but the devices employed for these purposes have been defective in various respects. Thus, for instance, the axle of various sulky attachments, as now constructed, will prevent the plow from being suitably raised from the ground, unless the plow-beam has been shortened, or specially constructed for this purpose.

My improved sulky attachment has also the advantage of being stronger and less complicated than those now ordinarily used.

In testimony that I claim the foregoing as my own I have hereto axcd my signature in the presence of two witnesses.
