ERNST C. A. PULS, OF SAN GERONIMO, TEXAS.
COTTON-CHOPPER.
EPECIFICATION forming part of Letters Patent -No. 353,463, dated November 30,1.886.
Application filed June 28, 1886. Serial No. 206,475. (No model.)To all wzho77 it 7may coicer,s
Be it known that I, ERNST C. A. PULS, of
San Geronimo, in the county of Guadalupe
and State of Texas, have invented a new and
5 useful Improvement in Cotton-Choppers, of
which the following is a full,- clear, and exact
description.
Reference is to be had to the accompanying
drawings, forming a part of this specification,
to in which similar letters of reference indicate
corresponding parts in both the figures.
Figure 1 is a side elevation, partly in sec-
tion and parts being broken away, of my im-
proved cotton-chopper. Fig. 2 is a sectional
15 front elevation of the same, taken through the
line x x, Fig. 1.
The object of this invention is to provide
cotton-choppers constructedin such a manner
that the cotton will be chopped to a stand by
20 the passage of the machine along the rows of
plants, leaving the hills of plants at uniform
distances apart, and which shall be simple in
construction, readily controlled, and conven-
ient in use.
25 The invention consists in the construction
and combinations of various parts of the cot-
ton-chopper, as will be hereinafter fully de-
scribed, and then claimed,
A represents the drive-wheels, the axle B
30 of which revolves in bearings in the lower
ends of hangers C. The upper ends of the
hangers C are attached to the lower sides of
the side bars of the frame D, the connection
being strengthened by braces E, the lower
35 ends of which are attached to the lower parts
of the said hangers, and their upper ends are
attached to the said side bars.
Upon the inner ends of the hubs of the
drive-wheels A are formed, or to them are at-
40 tached, ratchet-wheels F, with the teeth of
which engage pawls G. The pawlsG are piv-
oted to the outer ends of arms IH, and are held
against the said ratchet-wheels by springs I,
attached to the said arms and pawls. The
45 inner ends of the arms H have eyes formed in
them to receive the axle B, and are secured to
the said axle by set-screws J, or other suita-
ble means.
To the axle B is attached a large beveled
50 gear-wheel, K, into the teeth of which mesh
the teeth of a smaller beveled gear-wheel, L,
attached to the shaft M. The rear end of theshaft M revolves and slides in a sbcket in the
forward end of the coupling N, which has an
eye in its rear end to receive and ride upon 55
the axle B. The middle and forward parts of
the shaft M revolve and slide in bearings in
the centers of the curved bars 0, the ends
of which are attached to the side bars of the
frame D. 60
The forward part of the shaft M is made
square, and to it is secured, by bars or clasps
P and bolts Q, two parallel slotted bars, R.
The bars or clasps P have square recesses
formed in them, to receive the square part of 65
the shaft M and hold the bars R from turn-
ing upon the said shaft.
S are the chopping-hoes, upon which are
formed, or to them are attached,shanks T, the
ends of which have forwardly-projecting lugs 70
U formed upon them, to fit into the slots of
the bars R and prevent the said shanks from
turning upon their fastening - bolts V. The
bolts V pass through holes in the shanks T,
and through the slots in the bars R, so that the 75
hoes S can be adjusted, by loosening the nuts
of the said bolts, to work deeper or shallower
in the ground, as may be required.
W is a frame which passes around the axle
B,thesocket-coupling N, and the beveled gear- 8o
wheel L, and has a hole in its front bar to re-
ceive the shaft M. Upon the front bar of the
frame W is formed, or to it is attached, a U-
shaped extension-frame, X, through a hole in
the forward part of which the shaft M passes. 85
The arms of the extension-frame X are of
such a length that when the forward part of
the said extension-frame X is in contact with
the rear bar, R, the front bar of the frame W
will be in contact, or nearly in contact, with 90o
the forward end of the hub of thegear-wheel L,
so that the shaft TMl can be moved longitudi-
nally,to throw the gear-wheel L into and out of
gear with the gear-wheel IK, by moving the
frame W X. The rear end of the frame W is 95
pivoted to a lever, Y, the lower end of which
is pivoted to the for wardly-projecting lower
end of the hanger Z. The upper end of the
hanger Z is attached to the rear cross-bar of
the frame D, and the said hanger is strength- ioo
ened in place by the brace-bars a, attached to
the lower part of the said hanger and to the
side bars of the frame D. With the upper
part of the lever Y is connected a spring-lever
