ward, such latter movement resulting in a
consequent elevation or depression of the
machine-frame. Owing to the sliding move-
ment of shaft 23 within its brackets, its gear
5 may be moved into driving engagement with
the traction-wheel gear 15 irrespective of the
position of the traction-wheels, the feathered
mounting of the sprocket-gear on said shaft
allowing the latter to be moved there-
to through.
In its operation the machine is drawn for-
wardly, causing the rotation of the traction-
wheels and cutter-disks and effecting the
movement of the sprocket-chains, as above
15 described, the depth of cut of the disks being
adjusted by means of the connection between
the rocking axle and its operating-lever. As
the machine is drawn forwardly the fingers
on the sprocket - chains will engage the
stalks and pull the same downwardly be-
neath the chain-guides and into the path of
the rotating cutters, which will cut the stalks
into suitable lengths. A series of scrapers 33
are preferably secured to the rear transverse
25 beam 17, the scrapers being formed with the
customary V-shaped notches, in which the
cutters fit, the position of the scrapers being
adjusted to correspond with that of the cut-
ters.
30 The number of cutter-disks carried by the
shaft 9 may be varied at will, the interme-
diate beam 7 being dispensed with, when but
a small number of disks-as, for instance,
five-is made use of.
35 Further modifications and changes may
obviously be made within the scope of the
claims and without departing from the spirit
of the invention.
What is claimed is-
40 1. A stalk-cutter comprising in combina-
tion a frame including an axle, and traction-
wheels mounted thereon; a shaft journaled in
said frame in advance of said axle; a plurality
of cutters mounted on said shaft; a trans-
45 versely-disposed stalk-felling device carried
by the frame in advance of said shaft; and
means for operating said stalk-felling device.
2. A stalk-cutter comprising in combina-
tion a frame including an axle, and traction-
5o wheels mounted thereon; a shaft journaled in
said frame in advance of said axle; a plurality
of cutters mounted on said shaft; a trans-
versely-disposed stalk-felling device carried
by the frame in advance of said shaft, comn-
;5 prising a moving member provided with a
plurality of fingers; and means for driving
said member.
3. A stalk-cutter comprising in combina-
tion a frame including an axle; and traction-
6o wheels mounted thereon; a shaft journaled in
said frame in advance of said axle; a plurality
of cutters mounted on said shaft; a trans-versely-disposed stalk-felling device carried
by the frame in advance of said shaft and
comprising a chain; fingers carried by said
chain; guide-beams between which said chain
travels; and means for driving said chain.
4. A stalk-cutter comprising in combina-
tion a frame including a main shaft and trac-
tion-wheels mounted thereon; a shaft jour-
naled in said frame in front of said main
shaft; a plurality of cutters mounted on said
front shaft; a pair of depending brackets se-
cured to opposite sides of said frame in ad-
vance of said shaft; a shaft journaled in each
pair of brackets; a sprocket-wheel mounted
on each shaft; a sprocket-chain connecting
said sprocket-wheels; guides for said sprocket-
chain, carried by said brackets; fingers car-
ried by said sprocket-chain; a gear on the
rear end of one of said last-mentioned shafts;
and a gear on the adjacent end of one of said
first-mentioned shafts, in mesh with said first-
mentioned gear, for driving said sprocket-
chain.
5. A stalk-cutter comprising in combina-
tion, a frame; a shaft journaled in said frame;
a plurality of cutters mounted on said shaft;
a shaft journaled in said frame in the rear of
said first -mentioned shaft; traction-wheels
carried on opposite ends of said shaft; means
for rocking said rear shaft to change the posi-
tion of said traction-wheels bodily, and raise
and lower the frame; a transversely-disposed
stalk-felling device carried by said frame in
advance of said cutter-carrying shaft; and
means for operating said stalk-felling device.
6. A stalk-cutter comprising in combina-
tion a frame; a shaft journaled in said frame;
a plurality of cutters mounted on said shaft;
an axle mounted in said frame; in the rear of
said shaft; traction-wheels mounted on oppo-
site ends of said axle; a pair of depending
brackets secured to opposite sides of said
frame in advance of said shaft; a fixed shaft
journaled in one pair of brackets; a longitu-
dinally-movable shaft j ournaled in the oppo-
site pair of brackets; a gear secured to the
rear end of said movable shaft; a sprocket-
wheel mounted on each shaft; a sprocket-
chain connecting said sprocket-wheels guides
for said sprocket - chain carried by said
bracket; fingers carried by said sprocket-
chain; and a gear formed on the inner face of
one of said traction-wheels, into engagement
with which the gear on said longitudinally-
movable shaft is adapted .to be moved, to
effect the rotation of said sprocket-chain.
In testimony whereof I affix my signature
in presence of two witnesses.
THOMAS L. DURHAM.
