WILLIAM H. MoCLAUGHERTY, OF SEGUI\, TEXAS.
IMPROVEMENT IN COTTON SCRAPERS AND CHOPPERS.
Specification forming part of Letters Patent No. 160,111, dated February 23, 1875; appliesation filed
November 14, 1874.To all whom it may concern:
Be it known that I, WILLIAM H. M-
CLAUG MRTY, of Seguin, in the county of
Guadalupe and State of Texas, have invent-
ed a new and useful Improvement in Com-
bined Cotton Scraper and Chopper, of which
the following is a specification:
Figure 1 is a top view of my improved ma-
chine. Fig. 2 is a vertical longitudinal sec-
tion of the same, taken through the line x x,
Fig. 1. Fig. 3 is a vertical cross-section of
the same, taken through the line y y, Fig. 1.
Fig. 4 is a detail cross-section taken through
the line z z, Fig. 1, showing the gear-wheel
clutch. Fig. 5 is a detail section of the ad-
justable chopper-arm, taken through the line
v v, Fig. 3. Fig. 6 is a detail section taken
through the line wo ov, Fig. 1.

sponding parts.
My invention has for its object to furnish
an improved machine for scraping cotton and
chopping it to a stand, which shall be so con-
structed that it may be readily adjusted to
leave the hills at any desired distance apart,
and to scrape the ridge to any desired depth,
and which shall be simple in construction,
easily guided and controlled by the driver,
and effective and reliable in operation.
The invention consists in the construction
and combination of the various parts, as will
be hereinafter fully described, and set forth in
the claims.
Ais the frame of the machine, to the under
side of the rear part of the side bars of which
are attached bearings, in which revolve the
journals of the axle B. C are the wheels, one
of which revolves loosely upon, and the other
is rigidly attached to, the axle B, so that the
said axle may be revolved by the advance of
the machine. To the axle B, a little at one
side of its center, is attached a large bevel-
gear wheel, D, the teeth of which mesh into
the teeth of the small bevel-gear wheel Ei
placed upon the shaft F, and connected with
it by the clamps G, which consists of two
bars connected at their ends by bolts. The
bars of the clamps G are placed in slots in
the forward end of the wheel E, and theirmiddle parts rest upon the shaft F, which is
made polygonal at that point.
By this construction, should one of the
chopper-knives strike an obstruction, the bars
of the clamp G give enough to allow them to
pass an angle of the shaft F, by which time
the knife will be carried forward far enough
to pass the obstruction.
The rear end of the shaft F revolves in
bearings in an upright block, H, which has a
pivot formed upon each end. The upper pivot
of the block H works in a hole in the forward
end of the upper bar or plate I, and its lower
pivot works in a slot or notch in the forward
end of the lower bar or plate J. The rear
ends of the bars or plates I J are attached to
the rear cross-bar of the frame A, and the
forward parts of the said bars or plates are
connected with each other, and held at the
proper distance apart by the nuts screwed
upon the tie-rod K above and below each of
the said bars or plates, as shown in Fig. 2.
This construction allows the forward end of
the shaft F to be moved vertically to regulate
the depth at which the chopping-knives work,
and to be moved laterally for convenience in
detaching the said shaft and its attachments
when desired.
The forward end of the shaft F works in a
U-bar, L, placed in a notch in the rear side of
the cross-bar a', of the frame A. The ends
of the arms of the U-bar L are bent outward
at right angles, and to them are swiveled the
screws M, which pass down through the said
bar a', and through stationary nuts N, se-
cured in said bar, so that by turning the screws
M the bar L may be raised or lowered to ad-
just the choppers, as may be required.
The forward part of the shaft F is made
square to fit into the square holes formed in
the centers of the two cross-bars, 0, which
are placed upon the shaft F at right angles
with each other, and are held in place by set-
screws o'.
To the ends of the cross-bars O are attached
triangular knives or cutters P, with an angle
forward and slightly inclined toward the front
end of the machine, so as to pass through the
ground squarely as they revolve, and at the
