AUGUST HILLERMANN AND CHRISTOPHER HEINN, OF HENRIETTA, TEXAS.
COTTON-CHOPPER.
SPECIFICATION forming part of Letters Patent No. 615,175, dated November 29, 1898.
Application filed November 20, 1897. Serial No. 659,321, (No model.)To all whom d imay concern:
Be it known that we, AUGUST HILLERMANN
and CHRISTOPHER HEINEN, citizens of the
United States, residing at Henrietta, in the
5 county of Clay and State of Texas, have in-
vented certain new and useful Improvements
in Cotton-Choppers; and we do hereby declare
the following to be a full, clear, and exact de-
scription of the invention, such as will enable
[o others skilled in the art to which it appertains
to make and use the same.
Our invention relates to certain improve-
ments in cotton-choppers which are equally
adapted for agricultural purposes generally
15 wherein plants or the like require thinning
out in their cultivation.
It has for its object to cause the knives or
cutters to act successively upon the cotton
or plants or rows and to permit them to be
20 readily varied or one or more removed to ad-
just them greater or less intervals apart ac-
cording to extent it is required to thin out the
plants or shrubbery.
The invention is also characteristic for its
25 steadiness of operation, facility and ease of
manipulation, and simplicity of construction,
and can be built at a minimum cost.
It consists, primarily, of the individual con-
struction of the knives or cutters, their adapt-
30 ability for varied arrangement along their
carrying bar or frame, and the construction
of their carrying-frame, and means to pro-
vide for the limited independent movement
of either of the transporting or main drive
35 wheels either back or forth, as may be re-
quired in turning the machine; also, of means
to enable the cutters or knives to cut deep or
shallow, all substantially as hereinafter more
fully disclosed, and specifically pointed out
40 in the claims.
In the preferred embodiment of our inven-
tion, illustrated in the accompanying draw-
ings, Figure 1 is a longitudinal section there-
of. Fig. 2 is a broken plan showing more
45 fully the seat-securing bolts and nuts. Fig.
3 is a broken enlarged detail view showing
more fully the detachability of the cutters or
knives and means for holding the same on
their carrying-frame. Fig. 4 is a side eleva-
50 tion of the knife-carrying frame and its cut-
ters or knives. Fig. 5 is a detailed view show-ing chiefly just how the levers G hold the
frame D.
In carrying out our invention it will be pre -
mised that all matters pertaining to details 55
of the construction and arrangement of the
aforesaid parts are to be treated simply as ex-
pedients, as they may be changed or varied
as the judgment may suggest.
A refers to a frame, with a seat B prefer- 6o
ably mounted or secured upon it, sulky-like,
at its rear end, said frame being supported
near its forward end upon an axle a, provided
with wheels b. The seat is preferably held
or secured at the lower corner edges of its side 65
supporting portions by four nutted bolts a',
passing through flanges thereof and, it may
be, through the frame side pieces or other-
wise adapted to make connection therewith.
By removing the nuts of three of these bolts 70
and properly withdrawing the latter and loos-
ening the nut of the fourth the seat may be
swung to one side to allow the removal of the
knife-carrying frame when desired.
C C are two series of cutters or knives with 75
their blades or cutting portions c each ar-
ranged about at an angle of forty-five de-
grees to its shank c', and D is a frame carried
by a shaft D', passing about centrally there-
through and suitably supported in bearings 8o
e e', secured to the frame A upon its under
side. The knives or cutters C C have their
shanks c' passed through slots or apertures
d in the end or cross pieces of the frame D,
with their cutting edges presented at right 85
angles to the line of travel of the machine,
obviously to cut or thin out the cotton or
plants in the path of their movement. Passed
through apertures c2, one in the shank por-
tion of each cutter or knife of each series, is 90
a rod c3, also passed through apertures c' in
the side pieces of the frame D, the ends of
said rods being suitably nutted on the outer
sides of said side pieces, thus providing for
securing in place each series of knives by a 95
single rod or key. Also it will be seen that
by temporarily withdrawing the rods or keys
one or more of the knives or cutters can be
removed and the distance between the same
be varied, and the cotton or plants thus be too
thinned out to a greater or less extent, as de-
sired.
