CULTIVATO R.

SPECIFICATION forming part of Letters Patent No. 284,062, dated August 28, 18.83.

Application filed May 2z?, 1883. (No model.)

To @ZZ whom, #may concern:

Be it known that I, HENRY G. RIKARD, of Monroeville, in the county of Monroe and State of Alabama, have invented certain new and useful Improvements in Cultivators 5 and I do hereby 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 pertains to make and use it, reference being had to the accompanying drawings, which form part of this speciiication.

My invention relates to an improvement in cultivators; and it consists, in combination with the standard and a bolt which secures the standard to the beam, of4 a pivoted colter which is placed upon the bolt and which is provided with a projection upon its inner side, so as to catch against the front side of the standard, and thus prevent it from being moved too far backward, as will be more fully described hereinafter.

Figure 1 is a side elevation of my invention. Fig. 2 is a plan view of the same: Fig. 3 is a perspective of the colter.

A represents the central beam of the frame, and C the slotted cross-pieces, which are rigidly secured thereto, as shown. These crosspieces are slotted at their outer ends, so that the side beams,.D, can be adjusted laterally back and forth for the purpose 'of moving the colters any desired distance apart. Secured to the under side of the beam A, at each end, just under the cross-pieces, are slotted iron plates or cross-piecesG, which serve as guides and braces to the side beams in their lateral movements. In case it is not desired to use slotted metallic plates, as is here shown, but which will be found preferable, a second slotted wooden crossipiece may be substituted for each one of the slotted iron plates. Each one of the standards II has its upper end formed or pivoted so as to pass up over each side of the beam, and these upper ends are united by means of a clamping-bolt, I, by means of which the upper ends can be drawn together with sufcient force to clamp the standards inany desired position upon the beam. Pivoted between the sides of each standard, at any suitable distance below the edge of the beam, is a connecting-rod, J, which extends backward any suitable distance, and has its rear end fastn ened to the lower end of the U -shaped clamp L, which is secured to the beam by means of tightening-nuts upon its screw-threaded ends. By tightening the nuts upon these clamps the clamps will be held rigidly in position, and the connecting-rod will then serve as a brace for the standard to prevent it from moving backward. The clamping-bolt which passes through the upper end of the standard serves to clamp the standard rigidly in position at its upper end, and its lower end is held in place by means of the clamp and the connecting-rod. In case it should be desired to change the angle at which the standard is adjusted, it will only be necessary to loosen the clamp, and either force it forward or back upon the beam, and then the standard will adj ust itself.

In order to apply a colter to thestandard of a cultivator or plow and make the colter adjustable, the colter I? is here secured to the side of the standard by the same bolt which passes through the upper end of the standard and secures it in position upon the beam. The

colter then extends downward to any desired distance, and can be turned up out of the way when not needed for immediate use. /In order to hold this colter in position when it is desircd for use, a hook, arm, lug, or projection, Q, is formed upon its inner side, and this part Q catches over the edge of the standard, so as to prevent the colter from being forced back ward.-

Having vthus described my invention, I claim- 1. The combination of the standard with a pivoted colter secured upon its side,` substantially as set forth.

2. rIhe combination of the standard with a colter which is pivoted thereto, and provided with a suitable projection upon its inner side to catch over the front edge of the standard, substantially as specified. V

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

HENRY C. RIKARD.
