C U LT I VAT 0 R SPECIFICATION forming part of Letters Patent No. 449,522, dated March 31, 1891.

Application filed December 24, 1890. fierial No. 375,761. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM S. COOK, a citizen of the United States, andaresident of Jackson, in the county of Butts and State of Georgia, 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 to letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in cultivators, the object being to so improve said implements as to render them more cheap and durable and at the same time operative to a more satisfactory degree than heretofore, the invention consisting of a novel form-of straddle-row cultivator and fenders for protecting the plants, the details of all of which will be hereinafter fully specified, and the points of novelty fully set up in the claims.

In the accompanying drawings, Figure l is a side elevation of the device, showing the long beam and one of the fenders. Fig. 2 is a plan of the device, showing all the parts assembled. Fig. 3 is a rear elevation of Fig. 2, the handles, standards, and shares beirg omitted for the purpose of clearness.

In the figures like reference-characters are employed for designating corresponding parts in all the views.

Thelongbeam A is of the same construction as commonly used for one-horse plows, the short beam B being set parallel thereto and held adj ustably in that position by means of the transversely-extending bars 0 and O, which are provided at each of their ends with several adj listing-holes, by means of which and bolts passing downward through them and through the beams A and 13 the said adj ustment is performed, its limit being set by the number of said holes. A brace D from the front end of the beam extends to the forward end of the beam A and prevents any backward movement of said beam A. Thus it will be seen that by means of only three braces the two beams are effectively united into a satisfactorily-operative straddle-row cultivator in which the draft-beam A cannot be broken by reason of the braceD and which .struction.

The clevis is attached to the front end of the beam A and the handles are secured, as usual, one to each of said beams, braces a being employed to insure the proper angle of the same relative to the beams. By means of the several holes in either the top or bottom end of the said brace a the handles may be adjusted as tothe height of their back ends to accommodate them to the stature of the person using the implement.

The forward brace O has a slot 0 therein, in which is inserted the eyebolts (I, having a screw-threaded portion and nuts, one above and one bclowsaid transverse piece 0 thereon, and by loosening one nut and tightening the other one vertical adjustment of said eyebolts may be had. Pivoted by its corner to the lower endof said bolt (Z is a plate E, which extends backwardly past the standard and has a narrow elongation e, which is carried by a bolt 6 in the slot formed by the loop in the bracket 6 which is secured to the beam A near its back end. By loosening said bolt 6 it may be moved in said slot and the normal position of the fender be so adjusted upward, motion for release in emergency being provided for by the upward elongation of the slot above the top of the elongation e. The hole through which passes the bolt 6 which secures the bracket e to the beam, is slotted, and by movement of said bracket thereon and the movement of the bolt d in the slot 0 in the cross-piece O the plate E may have sidewise adjustment to and from the plowshare. A second plate E, which is pivoted to the cross-piece O in the same manner as the plate E and is the same size, should stand at substantially the same angle to a distance from the beam 13 as the plate E is from the beam A.

In order to preserve the proper distance between the plates E and E at their back ends,

a rod F is screw-threaded on both ends and inserted in suitable apertures in the said plates at their upper back corners and a nut placed thereon on each side of each plate, and it is obvious that any reasonable adjustment relative to each other may be had, and if desired said plates may be set converging backwardly, so that the dirt will be thrown up slightly around the plants. In no other fender is sulficient stiffness and strength had to perform this often advantageous operation. In order that the rod F may not injure high plants, it may be curved upwardly, as best illustrated in Figs. 1 and 3. The motion of the blades E and E is, by reason of this rod F, simultaneous, and the elongation 6 controls through said rod vertical motion of said blade E on its pivotal point on the bolt (Z.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In adevice of the class specified,thebcam A, having a laterally-extending bar secured thereto and the fender-plate partially secured to said bar and extendingbackwardly,carrying on its back end an elongation reduced in size, and the bracket secured to the back end of a plow and having a vcrtically-slot-looped portion wherein the said elongated reduced portion of the fender-plate works, its downward motion being limited by the bolt 0' passing through said slot, all combined, arranged,- and operating substantially as and for the purpose specified.

2. In a device of the class specified, the beams A and B, held relatively stationary and having a cross-bar O, and the plates E, depending from said cross-bar, their back ends being held relatively stationary by means of a bolt F, secured at each end to one of said plates, and the hanger or bracket 6 substantially as shown and described, and for the purpose specified.

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

WILLIAM S. COOK. \Vitnesses:
