I, HERBERT JOHN ALLISON, of 52 Chancery Lane, London, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention (which has
been communicated to me from abroad by Stanley Singleton Stout and Harold Green
Underwood, of 66 Wisconsin Street, Milwaukee, in the County of Milwaukee, and
State of Wisconsin, one of the United States of America, Patent Solicitors) to be as
follows:-
This invention relates to Harvester Reels of that class wherein the blades may be
adjusted at an angle to the cutting-bar of the machine while in motion, in order to
straighten such grain as may be storm lodged, or bent over by the wind and other
causes, thus causing it to fall squarely across the platform when cut.
The reel has a horizontal tubular shaft hung in suitable bearings, through which
shaft there extends a rod that is connected at its inner end to a suitable shifting lever,
designed to come within convenient reach of the operator of the machine. Loosely
fitted on this shaft are two heads held in place against an interposed block by means
of collars, this block being formed with radial right angular extensions, and made fast
to said shaft by a set-bolt.
The block and its extensions are provided with bearings for the trunnions of cranks
that are pivotally connected to links which pass through suitable apertures in the outer
reel head, and unite with the respective ends of a cross-piece that is centrally secured
to the outer end of the rod first named, thus forming a head to said rod (or, the
outer end of the rod may be formed in one piece, with wings.)
Near its outer end, the rod is provided with a slot and when this rod is acted upon
by the shifting lever its play is limited by means of a pin that passes through the
furthest collar and the tubular shaft. Each of the described cranks near the end that
is trunnioned to a block extension is formed with toothed segments that mesh with
similar segments on the respective reel heads, and thus, when the rod is operated by
the shifting lever, these heads are partially rotated on the tubular shaft in an opposite

page_text: direction one to another, this result being accomplished through the link connection
cf said crank and rod.
Both reel heads are provided with a series of radial sockets in which are rigidly
secured the inner ends of the reel arms, whose outer ends are loosely connected to
blades that come in contact with the grain when the machine is in operation.
Supposing the soveral blades to be standing parallel to the cutter-bar of the
machine, and it is desired to place them at an angle thereto, the movement of the
shifting lever in or out serves, through the intermediate mechanism described, to
partially rotate the two reel heads in opposite directions, causing the inner and outer
series of reel arms to correspondingly change their positions, and carry with them the
respective loosely connected ends of said blades, thus accomplishing the desired result
without stopping the machine. When the lever is drawn in, the reel blades will
assume such an angle as to raise such grain as may be bent down in a direction away
from the machine while, by pushing the lever out, a reverse operation will be
effected.
By having both reel heads loose on the shaft, the blades may be more readily
adjusted and with less friction, than would be the case were one of the heads stationary,
as it requires but one-half as much movement of the lever to throw said blades in a
given direction.

Improvements in Harvester Reels.
I, HERBERT JOHN ALLISON. of 52 Chancery Lane, London, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention (which has
been communicated to me from abroad by Stanley Singleton Stout and Harold Green
Underwood, of 66 Wisconsin Street, Milwaukee, in the County of Milwaukee, and
State of Wisconsin, one of the United States of America, Patent Solicitors,) and in
what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention relates to that class of harvester reels wherein the blades may be
adjusted at an angle to the cutter-bar of the machine while in motion, in order to
straighten such grain as may be storm-lodged or bent over by wind and other causes,
thus causing it to fall squarely across the platform when cut.
The invention therefore consists in certain peculiarities of construction and arrange-
ment of parts, as will be hereinafter described with reference to the accompanying
drawings and subsequently claimed.
Figure 1 represents a front elevation of the reel in operative position.
Figuro 2 a plan view showing the means for operating the reel-blades.
Figure 3 a front view of the same.
Figure 4, an end view.
Figure 5, a vertical section on line 2, Figure 3.
Figure 6, a horizontal section on line y y, Figure 3; and
Figure 7, a detail showing the connection of the blades with the inner reel-arms.
Referring by letter to the drawings, A represents a portion of a harvester-frame to
which the reel is operatively connected, the horizontal shaft B of said reel being
tubular and hung in suitable bearings.
Through this tubular shaft B extends a rod, C, that is connected at its inner end to
a suitable shifting-lever, D, the latter designed to come within convenient reach of the
operator of the machine. Loosely fitted on the chatt B are heads E F, held in place
against an interposed block, G, by means of collars a b, this block being formed with
radial right-angular extcusions and made fast to said shaft by a set-screw, d, this
construction Leing shown in detail, Figure 5.
The block G and its extensions c are provided with bearings for the trunnions e of
cranks H, that are pivotally connected to links I, the latter passing through suitable

page_text: apertures,, in the outer reel-head, F, and uniting with the respective ends of a
cross-piece, g, that is centrally secured to the outer end of the rod C, thus forming
a T-head to said rod. Instead of the cross-piece being secured to the rod, as above
described, the outer end of the latter may be formed in one piece with wings that
would serve the same purpose. Near its outer end the rod C is provided with a slot, h,
and when this rod is acted upon by the lever D its play is limited by means of a pin, i,
that passes through the collar and shaft B to engage said slot, as shown by
Figure 6. Each crank H, near the outer end, that is trunnioned to an extension, c, of
the block G, is formed with toothed segments m, that mesh with similar segments, n,
on the respective reel-heads E F, and thus, when the rod C is operated by the lever D,
these heads are partially rotated on the shaft B in an opposite direction one to the
other, this result being accomplished through the link-connection of said crank and rod.
Both reel-heads E F are provided with a series of radial sockets, those of the
former being denoted by the letter », while those of the latter are markeds and cause
the radial arms to stand at an angle to the face of the last-named head. In these
sockets are rigidly secured the inner ends of the reel-arms K L, respectively, their
outer ends being loosely connected to blades or bats M, that come in contact with the
grain when the machine is in operation.
The blades M are connected to the outer ends of the reel-arms K by means of
angular straps t, secured to said arms by bolts or other suitable means, this construc-
tion being illustrated in detail, Figure 7.
The reel-arms L are at an angle corresponding to that of the sockets s on the
head F, and have their outer ens foosely inserted in bearings u, that are secured near
the outer extremities of the blades M, by pins passed through the end of said
bearings and into said ends of the arms, to thus form a pivotal connection between
the parts. Supposing the several blades to be standing parallel to the cutter-bar of
the machine, and it is desirable to place them at an angle thereto, the lever D is
moved in or out, and through the intermediate mechanism described partially rotates
the two reel-heads in opposite directions, this movement causing the inner and outer
series of reel-arms to correspondingly change their positions and carry with them
the respective loosely-connected ends of said blades, thus accomplishing the desired
result without stopping the machine. When the lever is drawn in, the reel-blades will
assume such an angle as to raise such grain as may be bent down in a direction away
from the machine, while by pushing the lever out a reverse operation will be effected,
this latter position being illustrated by Figure 1.
By having both reel-heads loose on the shaft the blades may be more readily
adjusted with less friction than would be the case were one of the heads stationary, as
it requires but one-half as much movement of the lever to throw said blades in a given
direction.
Having now particularly described and ascertained the nature of the said invention,
as cominunicated to me by my foreign correspondents, and in what manner the same
is to be performed, I declare that what I claim is :-
1. The combination, with a tubular reel-shaft, radial arms, and horizontal blades, of
the two heads having loose bearings on the shaft and provided with toothed segments,
a block having radial right-angular extensions and rigidly secured to said shaft
between the heads, cranks trunnioned in the block and extensions thereof, and provided
with toothed segments that mesh with those on said heads, and a sliding rod operative
in the shaft and having a link-connection with the cranks.
2. The combination, with a tubular reel-shaft, radial arms, and horizontal blades, of
the two heads provided with toothed segments and having loose bearings on the shaft,
a block rigidly secured to said shaft between the heads and provided with radial right-
angular extensions, cranks trunnioned in the block and extensions thereof, and
provided with toothed segments that mesh with those on said heads, a sliding rod
operative in the shaft and having its outer end provided with a cross-piece or
equivalent thereof, and links uniting the latter with the cranks.

page_text: 3. The combination, with a tubular reel-shaft, radial arms, and horizontal blades
loosely connected to said arms, of the heads having loose bearings on the shaft, a
block having radial right-angular extensions and rigidly secured to said shaft between
the heads, cranks trunnioned in the block and extensions thereof, and provided with
toothed segments that inesh with those on said heads, a slotted sliding rod operative in
the shaft and having a link-connection with the cranks, and a pin that engages the
slot in said rod.
4. The combination, with the reel-shaft, of two heads, each having a loose bearing
on said shaft and each having radial sockets, reel-arms rigidly secured in said sockets,
horizontal blades loosely connected to the outer ends of the reel-arms, and a lover
and connecting mechanism for rotating said heads in opposite directions.
Da so day of January 1000.
