TO ALL WHOM IT MAY CONCERN:
Be it known that we, A. K. FOSTER and B. H. FOSTER, of Hallettsville in the county of Lavacca, and State
of Texas, have invented a new and improved Cotton Cultivator; and we do hereby declare that the following is
a full, clear, and eXact description thereof, which will enable others skilled in the art to make and use the same,
reference being had to the accompanying drawings, forming a part of this specification, in which-
Figure 1 is a side sectional view of my invention, taken in the line x z, fig. 2.
Figure 2, a plan or top view of the same.
Figure 3, a rear view of the same.
Figure 4, an inverted plan of the share pertaining to the same.
Figure 5, an enlarged central view of the driving-wheel pertaining to the same.
Similar letters of reference indicate like parts.
The invention relates to a new and improved cultivator, designed more especially for cultivating cotton,
scraping the earth away from the young plants. and thinning out the same. The invention consists of a share
or scraper, composed of two parts, and a reciprocating. cutter, operated from the driving-wheel, or the wheel
which supports the implement, as hereinafter fully shown and described. A represents a beam, and B B are
two handles which are connected by a bar, C, the latter being secured to the rear part of the beam, and serving
to support the handles. The handles are also connected by a bar, a*, which serves as a brace for the same. D
represents a wheel, the axle b of which is attached to the-beam A. This wheel; D, has two annular, concentric
grooves, e c', made in one side of rim, said grooves being of T shape in their tran verse section, in order
that nuts, a, may be fitted in them to receive screws, b', and admit of said screws being firmly secured in the
grooves at any point desired. This will be fully understood'by referring to fig. 5. The nuts may be withdrawn
from the grooves by having a transverse groove or recess, b*, made in the rim b for the nuts to pass through.
E represents the share, which is composed of two parts, d d, placed or arranged in V form, as shown clearly in
figs. 2 and 4, a space, e, being allowed between the front ends of the parts d d, so that a part, d, may operate
at each side of a row of plants. The parts d d are secured near their front ends to the bottom of a standard,
F, the upper end of which is firmly bolted to the beam A, the parts d being each provided with a lateral or hori-
zontal plate, C, at their upper edges, which lap one over the other, and have oblong slots, f, made in them,
through which, and the lower part of the standard, a bolt, g, passes. The rear ends of the parts d'd are attached
by pivots, A, to a bar, H, secured to the lower ends of the handles B B, and it will be seen that by loosening the
bolt g, the front ends of the parts d d may be adjusted at a greater or less distance apart, and then secured in
the position desired by tightening up said bolt. The share may be adjusted higher or lower, according to the
depth of penetration required, by having the standard F provided with a screw, i, at its upper end, the screw
passing through the beam A, and having two nuts, j ], upon it, one above and the other below the beam, as shown
in fig. 1. One side of the standard projects up by the side of the beam, and has a vertical slot made in it,
through which a screw, 1, passes into the beam. By these means the standard, and consequently the share, may
be adjusted higher or lower, and firmly secured at the desired point. I represents a rock-bar, the front bearing,
sm, of which is attached to the beam A, the rear bearing being in a lever, J, the lower end of which is connected
by a fulcrum pin, n, to a pendant,.o, attached to the beam. This rock-bar has two arms, p p', projecting from it
at right angles, and from the same side, towards the wheel D, the arms pp', being in the path of the screws b,
so that the latter will.act against the former as the wheel D rotates under.the draught movement of the machine.
Through the rock-bar I, near its front end, two rods, K K, pass. These rods have screw-threads cut on their
upper ends to-receive nuts, g, two on each rod, one above and the other below the bar I. These rods extend
down between the rear ends of the two parts d d of the share, and have a cutter, L, attached, said cutter being
composed of two parts or plates, r r, with the lower ends of the rods K K secured between them, each part or
plate, r, having a cutting edge, s, projecting out from its lower end. (See fig. 3.) The lever J is retained in posi-
tion by a spring-catch, M, secured to the bar a* of the handles. As the implement is drawn along, the two parts
d d of tLe share E scrape the earth away from each side of the row of plants, while the cutters, L, thin out the
plants in consequence of working transversely across the row, the cutter being moved in one direction by the
heads of the screws in the inner groove e', striking the front arm, p', of the rock-bar I, and moved in the other
