SAMUEL A. DE FORCE AND WILLIAM V. McCONNELL, OF CROCKETT, TEXAS.
IMPROVEMENT IN COTTON SCRAPERS, CHOPPERS, AND DIRTERS.
Specification forming part of Letters Patent No. 222,255, dated December 2, 1879; application filed
September 22, 1879.To all whom it may concern:
Be it known that we, SAMUEL A. DE FORCE
and WILLIAMn V. MCCONNELL, of Crockett, in
the countyof Houston and State of Texas, have
invented a new and useful Improvement in
Cotton Scrapers, Choppers, and Dirters, of
which the following is a specification.
Figure 1 is a side elevation, partly in sec-
tion, of our improved machine. Fig. 2 is a
plan view of our improvement, partly in sec-
tion. Fig. 3 is a rear elevation, showing the
scrapers, the chopper, and one of the dirters.
Similar letters of reference indicate corre-
sponding parts.
The object of this invention is to furnish an
improved machine for cultivating cotton
which shall be so constructed as to bar off,
scrape, chop, and dirt the cotton upon both
sides of a row at one passage.
A are the wheels of a two-wheeled vehicle.
B is their axle, which is bent up in the form
of a bow, so that it will stand above the plants.
To the outer sides of the upright parts of the
axle B are pivoted two bars, C, the forward
ends of which are bent inward and forward,
and are attached to the opposite sides of the
rear end of the tongue D.
To the rear parts of the bars C are attached
two uprights, U, to receive a shaft, T, pro-
vided with arms S, and a lever, V, for raising
and lowering the operating parts of the ma-
chine.
To the inner sides of the upright parts of
the axle B are pivoted the forward ends of
two arms, E, with the rear ends of which are
connected the ends of a shaft, F.
Upon the shaft F are placed two wheels, G,
at such a distance apart as to run upon the op-
posite sides of the row of plants, which wheels
G should be secured in place adjustably by col-
lars or other convenient means, so that they
may be arranged wider apart or closer to-
gether, as may be required.
To the innot sides of the wheels G are at-
tached circular cutter-plates H, of steel, the
edges of which project so as to enter the
ground to a little greater depth than the
scrapers K, so that the said scrapers K will
not pull up or loosen any of the plants.
To the rear ends of the bars E, or to the endsof the shaft F, are pivoted the ends ofa bar, I,
which is bent twice at right angles, so that its
middle part may be parallel with the shaft F
and axle B.
To the bar I are secured by bolts the stand-
ards J, to the lower ends of which are secured
the scrapers K.
The scraper-standards J are slotted longi-
tudinally to receive the fastening-bolts, so that
they may be raised and lowered to adjust the
scrapers to work at any desired depth in the
ground. The bar I should be slotted longi-
tudinally to receive the bolts that fasten the
standards J of the scrapers K, so that the said
scrapers may be adj usted wider apart or closer
together to correspond with the adjustment of
the cutter-wheels G H, which slots are not
shown in the drawings.
To the inner side of one of the cutter-wheels
G H is attached a beveled-gear wheel, L, into
the teeth of which mesh the teeth! of a small
beveled-gear wheel, M, attached to the forward
end of the shaft of the crank N. The shaft of
the crank I revolves in bearings in the center
of the bar I and in a bracket or brace attached
to the said bar. To the crank Nis secured by
a bolt the shank of the chopper.plate or hoe
0, so that the said chopping-plate O may be
operated by the advance of the machine.
The shank of the chopper O should be slot-
ted to receive the fastening-bolt, so that the
said chopper may be adjusted to work at any
desired depth in the ground. The small gear-
wheel M should be movable upon its shaft, so
that it maybe thrown into and out of gear, as
required.
P are the dirting-plows, which are attached
to the rear ends of the standards Q. The
standards Q are bent into U form, and their
forward ends are secured to the bar I by bolts,
which pass through them and through longi-
tudinal slots in the said bar I, so that the
standards Q may be adjusted to bring the
dirting-plows P closer together or farther
apart, as circumstances may require. With
this construction, when the machine is drawn
forward, the plates H will separate the soil to
be operated upon from that in which the plants
stand, the scrapers K will bar off the plants,
the hoe O will chop them to a stand, and the
