IMPROVEMENT IN COTTON-SCRAPERS.

Specification forming part of Letters Patent No. 220,700, dated October 21, 1879 application filed August 25, 1878.

To all whom it may concern:

Be it known that I, LUKEQW. GARRAWAY, of Dry Grove, in the county of Hinds and State of Mississippi, have invented a new and valuable Improvement in Cotton Scrapers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is arepreseutation of a side view. Fig.2 is aplan view,the plowbeam broken away. Fig. 3 is a perspective view of the cotton-scraper detached from the p ow.

This invention relates to cotton scrapers, especially of that class having a turn -plow, and the main object is to reduce the ridge to the narrowest possible width, and to remove the weeds, grass, and other foreign plants from the rows of cotton in the field.

The novelty of this invention consists in the novel construction of a reversible scraper provided with a series of indentations in connec-' tion with a fastening device, whereby the point and cutting-edge can he raised or lowered to suit the bed, as will be hereinafter more fully set forth.

In the annexed drawings, forming a part of this specification, theletterArepresents aplowbeam, provided with handles B, arranged on 0pposite sides of the beam, at the rear end. 0 is a turn-plow, having substantially the usual share and mold-board, secured to a curved plowstandard, D, by means of one or more bolts and nuts, or otherwise.

The upper end, a, of the standard D is bent inwardly-that is to say, at rightangles-so as to overlap and rest upon the upper surface of the beam, orin areoess in the same. This curved standard, carrying the plow, is braced from displacement by means of the curved bar 0, attached directly to the standard and beam, substantially as indicated in Fig. 1 of the drawlegs.

The letter E indicates the diamoiiid-sha-ped scraper, constructed with two points, I; b, and two cutting or scraping edges, 6 6, with a uniformly-curved face, so as to be rendered reversible should one of the edges or points wear or be broken oft. This scraper is journaled or bolted to the short standard or barF by means of the bolt f and its washer and nut, in such a manner as to permit the scraper to be adjusted and reversed end for end.

The lower end of the bar F terminates-in a point or projection, so to speak, beyond the opening to receive the fastening-bolt, and is bent inwardly, forming a means, at, to engage with one of a series of indentations, h, arranged in the arc of a circle on the rear surface of the scraper E, substantially as shown in Fig. 3 of the drawings.

The standard of the scraper is attached to the plow-beam in advance of the plow by means of a yoke, clamp-screw, or other suitable fast ening device, and the lower portion of the standard is curved sidewise, so as to throw the forward portion of the scraper on one side and at an angle with the plow, so that the plow shall act in conjunction with the scraper, substantially as shown in Figs. 1 and 2 of the drawings.

It will be observed that the plow and scraper act independently and separately of each other in cutting their way through the soil, and will not be apt to choke or clog, while in turning the earth they act in concert. The earth taken up by the scraper will be passed onto the share and mold-board of the turn-plow and off into the space between the rows, and turned under to kill the grass and weeds.

It will be observed that the scraper has a double adj ustment-vertically by means of the standard and yoke, and the raising and low ering the point and cutting-edge to regulate the depth of cut by means of the indentations and the engaging device and fastening-bolt. Also, in changing the position of the ends I) b, the nut is only unloosed, which will prevent the engaging device from being disengaged from the indentations and the scraper revolved or turned upon the axis of the bolt f. After the proper adjustment is made, the nut is engaging with the indentations, and a bolt again adjusted home, which secures thescraper and nut, substantially as described.

in the new position.

WhatI claim as my invention, and desire to secure by Letters Patent, is-

The combination of an adjustable scraper having on its rear surface a series of indentations in the arc of a circle, a standard or bar having at its lower end a point or projection In testimony whereof I have hereunto subscribed my uame.

LUKE WARD CARRAWAY.
