WILLIAM P. DORRIS, OF MORO, TEXAS.
STALK-CUTTER.No. 818,876.
To(1 ( whom ii f may colncer:
Be it known that I, WILLIAM P. DORnIS, a
citizen of the United States of America, re-
siding at Moro, in the county of Taylor and
5 State of Texas, have invented certain new
and useful Improvements in Stalk-Cutters, of
which the following is such a full, clear, and
exact description as will enable others skilled
in the art to which the invention appertains
m o to make and use the same, reference being
had to the accompanying drawings, forming
a part hereof.
This invention relates to improvements in
stalk-cutters, and has for its object the pro-
15 vision of a simple and efficient attachment
for cultivators and harrows by the use of
which all stalks and vines in a field to be cul-
tivated may be quickly and thoroughly cut
down. This object is attained by the use of
20 the device illustrated in the accompanying
drawings; and the invention consists in cer-
tain novel features of the same, as will be
hereinafter first fully described and then par-
ticularly pointed out in the claim.
25 In the drawings, Figure 1 is a perspective
view of a cultivator-frame having my stalk-
cutter connected thereto. Fig. 2 is an en-
larged longitudinal section of the stalk-cut-
ter, and Fig. 3 is an enlarged view of the lon-
30 gitudinally-movable box for the stalk-cutter
axle.
The cultivator-frame may be of any de-
sired dimensions and is provided with the
usual arched axle 1, to which the attachment
35 is secured. In carrying out my invention I
employ a pair of longitudinal beams 2, the
front ends of which are forked, as shown at 3,
to fit over and receive suitable bolts, by which
they are secured to the arched axle.. Near
40 their front ends the beams 2 are connected by
a cross-bar 4, so as to impart the necessary
rigidity to the device, and near their rear
ends suitable foot-recesses 5 are provided.
Upon the rear ends of the beams are mounted
45 boxes 6, in which the ends of the axle of the
stalk-cutter are journaled. These boxes 6
consist of plates or straps provided with
semicircular recesses or grooves 7 to fit
around the beam and having their outer
50 ends bolted together. The inner ends of the
straps are formed with half-sockets 8, to re-
ceive the cylindrical ends of the cutter-axle 9,
and the said socketed ends of the plates are
likewise bolted together, so as to inclose and
55 hold the said axle. By this construction IPatented April 24, 1906.
am enabled to adjust the bearings 6 along the
beams 2 and secure them at any desirable
point upon the beams. The bolts are first
loosened, after which the bearings are shifted
along the beams, and then the bolts are again 6o
tightened, as will be readily understood.
This adjustability affords a simple means of
varying the depth to which the cutters will
enter the ground, as the beams 2 will neces-
sarily drop rearwardly from the arched axle 65
through their own weight, and consequently
if the cutter is shifted forwardly along the
beams it will not enter the ground to the
same extent as if it were closer the rear ends of
the beams. In order that the weight of the 70
beams may not rest entirely upon the cutter,
and consequently force the same too heavily
upOon the ground, I employ supporting-
springs 10, which extend between the upper
part of the arched axle 1 and the beams, as 75
shown and as will be understood. The front
ends of the beams are attached to the arched
axle, so as to permit a vertical play of the
beams, and these springs serve to cushion the
return of the beams after the cutter has 8o
passed over stones or other obstructions, so
as to prevent injury to the cutter - blades
through a forcible drop of the same to the
ground.
Secured upon the axle 9 near the ends of 83
the same by means of suitable brackets or
boxes 11 are disks 12, having beveled or
sharp edges and provided with a series of
radial notches in their edges. Fitted in the
said radial notches and extending between 90
the disks are blades 13, provided with sharp-
ened outer edges and connected in pairs by
straps 14, wlich have their opposite ends
bolted to the diametrically opposite blades,
as shown clearly in the drawings. The 95
straps 14 are so disposed as to prevent longi-
tudinal movement of the blades by coming
into contact with the disks or rotary cutters.
The construction described and shown per-
mits the blades to be quickly removed for re- ico
pairs or sharpening, as it is necessary only
to disconnect the straps from the blades and
then bodily lift the blades from the recesses
in the disks.
The operation of the device will be readily 105
understood. The cultivator or harrow is
driven over the field and the blades 13 all
engage the ground, so as to cause the cutter
to rotate, the said blades taking into the
ground so as to cut through the stalks and oSpecification of Letters Patent.
