UNTTED STATES ATENT Erice.

IM PROVEM ENT IN PLOW-CLEANERS.

Specification forming part of Letters Patent No. 7,274, dated April 9, 1850.

To all whom it may concern:

Be it known that I, JAMES F. REAsuv, of Darlington, in the county ot' Harford and State ot' Maryland, have invented a new and useful Improvement in Plows; and I do hereby declare that the following is a full, clear, and eX- act description ot' my plow'cleaner, reference 4 heilig had to the accompanying drawing, which forms part of this specitication, and represents a view in perspective of a plow with my improvement applied thereto.

My invention consists in a device for cleansing plows or standards, which is composed of a stationary share-blade attached to the plowbeam and projecting forward from the colter, and of a corresponding movable share-blade adapted thereto, which can be operated,when necessary, by the hand ot' the plowman in such manner that the weeds or other obstructions which are continually accumulating in the angle formed by the beam and the colter are divided into two portions, which fall to the ground on each side ofthe colter and leave it free to pass through the sod.

In the plow represented in the'drawing the stationary share-blade ct is secured to the side of the beam A and projects forward of the colter b. A movable share blade, c, is pivoted to the stationary one, the outer extremity of the pivot being supported by an iron strap, d. The shank c ot' this movable blade is connected by a rod, e, with the lower extremity of a handlever, g, pivoted to one of the handles h of the plow.

When the plow is in use the several members ofthe device occupy the positions in which they are represented in the drawing. It' weeds, brush, or other obstructions accumulate at the angle t' ofthe colter to impede its action, the hand ofthe driver is applled to force the npper extremity ot' the hand-lever forward, and this lever, acting through the rod e upon the movable share-blade, forces its cutting-edge against the mass ot' rubbish, which,I being included between the two share-blades, is di vided into two portions, which fall on each side ofthe advancing plow and leave the colter free to act upon the sod. When the mass is divided the movable share-blade is returned toits iirst position by drawing back the upper extremity of the hand-lever.

This device is applicable to all descriptions of plows without materially changing their form and arrangement. It may also be constructed and operated in various ways without affecting the principle of the invention.

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

The plow-cleanser constructed ot' two shareblades, substantially as herein set forth, for

the purpose of cutting in two the weeds and other obstructions which accumulate upon the colter, and thus detaching them therefrom.

In testimony whereofl have hereunto signed my name this 12th day of December aforesaid.

JAS. F. REASIN.
