Upon the shaft C, adjacent the outer sides
of the beams 11, are mounted two correspond-
ing cross-arms II I , arranged diametrically
opposite each other. These arms are provided
5 at each side the shaft with a series of perfo-
rations h, disposed longitudinally with rela-
tion to the arms, and in one of each series of
perforations is secured a lug or pin h', which,
during the rotation of the shaft, are adapted
1o to elevate the arms G and drop them upon the
shaft, causing a slight jarring of the latter.
I will now proceed to describe the carriage
which I prefer to employ in connection with
my invention. It will, however, be obvious
15 that I may employ any other adapted form
of carriage in lieu of the following construc-
tion without departing from the spirit and
scope of my invention.
I designates the axle, provided at its ends
20 with depending spindles i i, upon which are
mounted carrying-wheels J J. To the axle is
secured a tongue K, having its rear end bifur-
cated, and the arms k k formed thereby di-
verged, meeting the axle near its ends.
25 When the device is secured in position upon
the above-described carriage, the beam A is
seated in recesses k' k', formed in the arms k
at their upper side, and said beam is retained
therein by a similar beam L, disposed under
30 the arms k and bolted or otherwise secured
to the beam A.
To effect the vertical adjustment of the
cylinders or drums, I have provided two for-
wardly-projectingsegmental arms MI M,which
35 are in the present instance secured to the
arms ko of the tongue just in front of the axle,
and from their secured ends the arms MI pro-
ject upwardly between the beams B and arms
G. These segmental arms are each provided
40 with a series of perforations m, one of each
series being engaged by a pin N, disposed un-
der the beams 13 to retain them in the ele-
vated position to which they have previously
been adjusted.
45 Motion is transmitted to the cylinder-shaft
from one of the carrying-wheels through the
medium of a belt O engaging a pulley o on
the shaft and a pulley P mounted on the hub
of the adjacent carrying-wheel. The latter
50 pulley consists of a flanged ring fitted over
the inner end of the hub and rigidly secured
in place by wires p passed therethrough and
secured around two or more spokes of the
wheel. I have thus fully described the con-
55 struction of this pulley, owing to its adapta-
tion to other forms of carriages than that
herein shown and described.
Q designates a seat comprising sides q q,
back q', bottom q2, provided with an up-
60o wardly-projecting flange q3 at its front edge,
and the top q1 forming a receptacle Q' for
storing tools and an additional supply of
poison. The seat is further provided with a
back consisting of two upwardly-divergent
65 arms R, to which are secured elongated cross-
pieces 9, the whole being covered by cloth S
or other material designed to screen the oper-ator from the poison when the device is in
operation. With the present form of car-
riage the sides q are recessed at their lower 70
ends, as at q", and the seat is disposed be-
tween the beams B with the axle engaging
said recesses.
For bending the cotton-stalks so that the
leaves will be overturned and the poison de- 75
posited on the under side thereof, I have pro-
vided a transverse bar T, secured beneath the
beams B in advance of the cylinder-shaft.
This bar also serves to keep the cotton from
contact with the cylinders, preventing wear 8o
of the same, and it also serves to keep the
cylinders free from the moisture upon the
cotton-leaves.
I claim as my invention-
1. In a device for destroying cotton-worms, 85
the combination, with a stationary frame, of
vertically - adjustable arms pivotally con-
nected therewith, a shaft journaled at the
ends of said arms and carrying adjustable
foraminated cylinders or drums, and upward- 90
ly-projecting arms provided with perforations
adapted to be engaged by pins for retaining
the shaft-carrying arms in adjusted position,
substantially as set forth.
2. In a device for destroying cotton-worms, 95
the combination, with a rotatable shaft pro-
vided with foraminated cylinders or drums,
and with revolving cross-arms having trans-
versely-projecting lugs, of pivoted arms rest-
ing thereon and adapted to be elevated by said oo
lugs and dropped upon the shaft to jar the
same, substantially as set forth.
3. In a device for destroying cotton-worms,
the combination, with a carriage provided
with upwardly-projecting arms having series o05
of perforations, of beams pivotally connected
with the carriage and carrying at their rear
ends a rotatable shaft provided with forami-
nated cylinders or drums and pins adapted
to engage one of each series of perforations Io0
in said arms and disposed under the beams
to retain them in elevated position, substan-
tially as set forth.
4. In a device for destroying cotton-worms,
the combination, with a carriage, of vertically- 1 15
adjustable beams carrying a rotatable shaft
at their outer ends provided with foraminated
cylinders or drums, revolving cross-arms on
said shaft provided with opposing lugs and
arms pivotally mounted on the carriage and i20
adapted to be elevated by said lugs and
dropped behind the same upon the shaft to jar
the latter, substantially as set forth.
5. The combination, with a rotatable shaft,
rectangular in cross-section and provided at 125
points thereon with perforations, of cylinders
or drums comprising heads provided with
rectangular openings to receive said shaft,
a foraminated peripheral covering, and pins
adapted to engage one of each series of per- r30
forations at both sides the cylinders or drums,
substantially as set forth.
6. The combination, with a carriage pro-
vided with upwardly-projecting perforated
