CULLEN ROGERS SMITH, OF FENTRESS, TEXAS.
STALK-PULLER.No. 846,255.
Specification of Letters Patent.
Application filed July 28, 1906. Serial No. 328,179.To aU whom it may concern:
Be it known that I, CULLEN ROGERS
SMITH, a citizen of the United States, and a
resident of Fentress, in the county of Cald-
5 well and State of Texas, have invented a new
and Improved Stalk-Puller, of which the fol-
lowing is a full, clear, and exact description.
My invention relates to a stalk-puller es-
pecially adapted for pulling cotton-stalks
to from the ground; and the purpose of the in-
vention is to provide a machine which will be
compact, durable, and economic and by
means of which a powerful and steady pull
may be exerted on the stalks for the purpose
15 of extracting the stalks and their roots from
the ground and to improve upon the con-
struction of pulling-machines for which Let-
ters Patent were granted to me January 12,
1904, No. 749,636, to the extent that the
20 construction is much simplified and the ma-
chine is rendered more light without detract-
ing from its strength, and wherein the grip-
pers constitute links of endless chains having
guided movement in independent casings,
25 the opposing chains of grippers being in close
and automatically- adjustable relation to
each other throughout the full length of their
inner leads.
Another purpose of the invention is to pro-
30 vide pivoted supports for the gripper-casings
on the axle of the machine and means for
adjusting the casings so that the chain of
grippers may be rendered effective upon very
large or upon very small stalks and means
35 for raising and lowering the forward ends of
the casings to bring their shoes in more or
less close relation to the ground.
It is also a purpose of the invention to
carry the main drive-shaft, its clutches, and
40 all of the operating-levers above the top of
the casings, leaving their upper surfaces com-
paratively unobstructed, and also to provide
an adjustable draft device which draws direct
from the axle.
45 The invention consists in the novel con-
struction and combination of the several
parts, as will be hereinafter fully set forth,
and pointed out in the claims.
Reference is to be had to the accompanying
50 drawings, forming a part of this specification,
in which similar characters of reference indi-
cate corresponding parts in all the figures.

of grippers, illustrating the solid construc-
tion of grippers of one chain and the yield-
ing construction of grippers of the opposing
chain. Fig. 4 is an outer face view of one of 6o
the grippers; and Fig. 5 is a longitudinal sec-
tion through the forward end portion of one
of the casings, a sprocket-wheel for the chain
of grippers carried by the casing, and an ad-
justing device for the said wheel. 65
In the construction of- the machine two
parallel casings A and A' are employed,
which casings are tubular and are rectangu-
lar in cross-section and of any desired length,
each casing terminating at its forward end in 70
a pointed shoe B, which shoe is provided
with a rearwardly-extendlinghrizontal mem-
ber 10, that rests upon the ground when the
casings are in their lowest position, as is
shown in Fig. 1. 75
Each casing A and A' is of the same co-n
struction and consists of a top member 11,
which is sups orted upon the flanges 12 of a
series of arched center pieces 13. The top 11
of a casing is provided at its inner longitudi- 8o
nal edge with a downwardly-extending flange
14, and a corresponding flange 15 is provided
outwardly from the flange 14, forming a
guide-channel 16 for a purpose to be herein-
after mentioned. A longitudinal angular 85
bracket 18 is secured to the inner lower longi-
tudinal surfaces of the center pieces 13, and
said bracket 18 supports a horizontal chan-
nel-bar 19, in which bar a series of friction-
rollers 20 are horizontally mounted to turn 90
freely, and below the said bracket 18 a sec-
ond angular bracket 21 is secured, and a sec-
ond series of vertically- disposed friction-
rollers 23 is pivoted to the lower vertical
member of the said second bracket 21, as is 95
shown in Fig. 3. The friction-rollers 23 are
slightly in advance of the horizontal friction-
rollers 20, and their purpose will be herein-
after particularly referred to.
A longitudinal bracket 24 is secured to the 100
lower outer longitudinal edges of the center
pieces 13, and said bracket 24 is provided
with an upwardly-extending flange 22, and
each bracket 24 carries an auxiliary bracket
21a, and each latter bracket carries a friction- 105
roller 23a, which are immediately opposite
the rollers 23 and are for the same purpose.
An angle-bracket 17 is. secured to the top
plate 11 at its outer edge, extending sub-
stantially the length thereof, and the vertical iio
or downwardly-extending member of the
bracket 17 is within the plane of the up-
