ABRAHAM T. SHIPMAN, OF HONEY GROVE, TEXAS.
HAND COTTON-PICKING APPARATUS.:Specification of Letters Patent.
Patented Jan. 3, 1922.
Application filed October 11, 1920. Serial No. 416,085.
To all whom it may. concern:
Be it known that I, ABRAHAM T. SHIP-
MAN, a citizen of the United States, residing
at Honey Grove, in the county of Fannin
5 and State of Texas, have invented new and
useful'Improvements in Hand Cotton-Pick-
ing Apparatus, of which the following is a
specification.
My present invention has for its object
10 the provision of a simple, durable, light and
efficient cotton-picking apparatus adapted
to be conveniently carried and operated to
advantage by a farm hand.
To the attainment of the. foregoing the
15 invention consists in the improvement as
hereinafter described and deinitely, claimed.
In the accompanying drawings, hereby
made a part hereof:-
Figure 1 is a view illustrative of the
20 manner in which my novel apparatus is'
carried by a workman.
Figure 2-is a side elevation of the appa-
ratus with parts broken away.
Figure 3 is a top plan view of the ap-
25 paratus.
Figure 4 is a longitudinal section of the
apparatus.
Figure 5 is a section taken in the plane
indicated by the line 5-5 of Figure 4.
30 Figure 6 is a section taken in the plane
indicated by the line 6-6 of Figure. 4.
Figures 7 and 8 are views of details here-
inafter explicitly referred to.
Similar numerals of reference designate
35 corresponding parts in all of the views of
the drawings.
Among other elements my apparatus in-
cludes a sack 1 to receive the picked cotton.
The sack is provided with a. strap 3, de-
40 signed to extend over the shoulder and
breast of the workman after the manner
illustrated in Figure 1. On the. sack is a
belt or strap 4 which: is extended around the
waist of the workman.
45 At 5 are attachments of the general con-
flguration illustrated. The sack 1 is open
at each side sufficiently to receive the wide
ends of the attachments 5, and the wide
ends of the attachments are connectetd by
50 hooks 6 and eyelets ,7 to the open portions
of the sack and extend in the form of open
tubes to the small ends through which the
pickers operate.
As illustrated each picker of: my appara-
55 tus includes a rectangular casing 8 that iscomparatively large at the end attached to
tie sack and is diminished toward its oppo-
site en.At the sral end of the picker is
a projecting overhanging portion 8x which
has for its function to prevent the picker 60
hooks, hereinafter described. from catching
into the leaves of cotton plants. Extending
across the. large end of each picker casing
8 are shafts 10 and 11 the ends of which are
disposed in- anti-friction ,bearings 12 car- 65
ried by the walls of the casing 8. Carried
by the said shaft 10 is a sprocket wheel .13
on which. is mounted a picker chain 14
equipped with hooks 15; said hooks having
for their function to engage and remove 70
cotton from the bolls. A third shaft 16 is
also employed in combination with the
picker chain 14; said shaft 16 being disposed
in the comparatively small end portion of
the picker casing and being mounted in 75
anti-friction bearings and equipped with
a sprocket wheel 17. In this connection it
is to be understood that a wheel on the shaft
11 at the large end of the casing is equipped
with spikes 18 that serve to knock the cot- so
ton from the hooks 15 into.the sack. The
shaft 11 is rotated from the shaft 10
through the wheels 10 and 10 and the
belt 10 .
For the purpose of actuating the picker 85
I employ a spiral spring 19 one end of
which is connected ,t 20 to the wall of the
casing S. The opposite end of said spring
is strongly connected to the shaft of the
belt-carrying sprocket wheel, and in this 90
connection it will be understood that a
pulley 22 on the same shaft carries a cord
23 one end of which is fastened to the pulley
and the other end to the before mentioned
belt 4. From this it follows that when the 95
picker is extended the spring 19 is placed
under tension or compressed, and that the
expansion of said spring puts the picker
in motion, whereupon the hooks 15 will re-
move cotton from the bolls, and the spikes 100
18 will remove the cotton from the hooks
and cause the cotton to enter the sack. Some
of the spikes 18 are .arranged to work be-
tween the hooks 15 and others at opposite
sides of the hooks 15. Manifestly the cas- 105
ings 8 are manipulated through the medium
of the handles 2 thereon.
The top walls 30 of the casings 8 are
hinged and detachably fastened in closed
position through the medium of hooks 31 110
