IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 97,201, dated November 23, 1869; aniedated November 17, 1869. v

To all whom it may concern:

Be it known that I, A. B. KING, of 0amden, in the county of Preble and State of Ohio,

have invented a new and useful Improvement in Cultivators; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

This invention relates to an improvement in that class of cultivators, &c., which employ shields for the protection of plants; and it consists in a novel construction of shield, and also in a device for breaking down weeds in advance of the plow, to insure the covering of the same, as will hereinafter more fully appear.

In the drawing the figure represents a side elevation of my invention.

To enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.

A represents the plow-beam, to the rear end of which is attached the slanting standard B, having on its lower endthe mold-board C. At the forward end of the beam are two vertical metal strips, b-one on each side-whose ends project sufliciently far above and below the same to admit of their being secured by two bolts, a a. This latter arrangement forms a means of attachment for the weed-break O and the cultivator-beam D, the former of which is pivoted to the lower bolt, a, and the latter to the upper, 01. Both of these latter devices, however, are prevented from swinging freely by the braces d d, the former of which extends from the beam D to the lower bolt, and the latter from the break O to the upper bolt. The brace d is not rigidly attached to the break 0, but clasps it by means of an orifice,.through which the latter passes, and has a free sliding motion thereon, which is limited bya projection, d on the side of the break between the brace and the point of attachment to the bolt a. The cultivatorbeam, being rigidly braced, has onlyalimited motion, such as is afforded by the vibratory motion of the strips b. Its position is regulated bymeans of a screw, (1 on the bolt d. The

break 0 extends back parallel with and below the plow-beam A about half its length, when it is bent outward and extends nearly parallel with the mold-board, and at its extreme end is bent downward, its function being to break down weeds, &c., before theplow. The cultivator-beam D, which is attached to the upper bolt, a, extends back, slanting outward and downward nearly opposite the moldboard O, when it is bent downward at right angles and forms a standard, E, to the lower end of which is attached the cultivator-tooth e.

F represents a curved arm extending diagonally across the angle of the beam D, to which is pivoted theshield, which-swings freely thereon, and consists of theboot shaped piece f, to which are bolted the grooved strips of metal f, the rear ends of which are bent inward.

The machine is held by the handles H in the usual manner.

I am aware that breaks have been em-W ployed of similar construction to mine, but differently attached. 'I am also aware that shields of somewhat similar construction have been used, butin all cases rigidly attached. I do not therefore claim, broadly, either of these ideas in themselves; but

Vhat I do claim, and desire to secure by Letters Patent of the United States, is

1. The pivoted shield f, in combination with the beam D, as and for the purpose described.

2. The beam D, with its brace cl, constructed and arranged substantially as described.

3. The break 0, in combination with the brace cl and projection (1 arranged and 0p erated as and for the purpose set forth.

4. The plow described, having the weedbreak, cultivator, and shield, combined and arranged as described, for the purpose set forth.

This specification signed and witnessed this 18th day of March, 1869.

A. B. KING.
