WEEDING-MACHINE.

SPECIFICATJEON forming part of Letters Patent No. 397,735, dated February 12, 1889.

Application filed September 24, 1888. Serial No. 286,214. (No model.)

To to whom it may concern.-

Be it known that I, JAMES BIBBER MANS- FIELD, a citizen of the United States, and a resident of Millbridge, in the county of \Vashington and State of Maine, have invented certain new and useful Improvements in \Veeding-Hachines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appeitains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a perspective view of my new and improved weeding tool or machine. Fig. 2 is a side elevation of the same, showing the blade in full lines as it stands when the tool is being pushed forward and showing it in dotted lines as it stands when the tool is drawn back toward the operator; and Fig. 3 is a central longitudiiml vertical sectional view of the in'iplement.

The same letters of reference imlicate corresponding parts in all the figures.

My invention consists in a new and improved machine or implement for cutting the weeds and grass, runners, &c., from among strawberry and other light plant-s growing in rows; and my invention will be hereinafter fully described and claimed.

Referring to the several parts by letters A indicates the metal frame of my new and improved tool or implement, which is formed at the center of its upper or rear end with the metal socket B, in which is secured the lower end of the handle 0, this being along wooden handle of the requisite length. The lower parallel ends of the frame A are bent down and then slightly curved upward, as shown, and to these lower curved extremities is bolted or riveted a curved metal plate, D, of thin light metal, the said curved plate being secured to the under side of the ends of the frame A. This metal plate I), and also the lower ends of the frame, is curved so that both its rear and front longitudinal edges rise above the ground, so that the curved plate will pass readily over the ground. This broad metal plate prevents the cutter-frame from sinking too deeply into the ground, as will be hereinafter seen.

end for the reception of a thumb-nut, K. The 1 upper ends of the cutting-blade extend up outside of the frame A, and are formed with the perforations L L, through which the ends of the long pivot-rod pass, and the blade is thus pivotally secured to the upper rear end of the frame. Upon the outer side of the upper rear part of the parallel arms formed by the frame A are formed the metal stops M M, the upper half, N, of the rear ends of which lie parallel with the sides of the frame A, while the lower half, 0, of their rear ends is inclined forward, as shown. Now the upper ends of the cutting-blade are pivotally secured to the sides of the frame A, so that when the implement is pushed forward over the ground by its handle C the cutter frame or blade will turn or swing back on its pivotbolt, so as to bring the front cutting-edge of the blade into its best operative position, when the upper ends of the blade will come in contact with the upper half, N N, of the rear operative ends of the stops M M on the side of the frame A, and the blade will be thus held at the correct inclination to out the weeds, grass, runners, &c., as the machine is pushed forward, as shown in full lines in Fig. 2 of the drawings. \Vhen the operator draws the implement back by the handle, the cutting-blade will swing forward at its lower end until the upper ends of its sides come in contact, and bears against the lower inclined half, 0, of the rear ends of the stops M M on the sides of the frame A, and the cutter-blade will thus be held firmly in the position shown in dotted lines in Fig. 2 of the drawings, with its rear edge at the best angle to cut the weeds, &c., as the machine is drawn back by the operator. It will thus be seen that the device can be readily and rapidly used in cutting the weeds, grass, &e., from among strawberry Having thus described my invention, what 1 and other light plants growing in-rows, as it claim, and desire to secure by Letters Patent 0 can be propelled both forward and backward. of the United States, is
