I WILLIAM MCINTYRE CRANSTON of 36 Worship Street, Finsbury, Middlesex
Agricultural Engineer, do hereby declare the nature of this invention to be as follows:—
This invention relates to certain detail improvements in Harvesters.
1. In a special method or arrangement of appliances by which the machine at onc
side can be lifted bodily upon the main or drive wheel.
2. In a particular combination of gear with varying speed motion for operating the
reel from the lower drive roller of the elevator.
3. In a novel arrangement of appliances for operating the "Butter."
According to the first improvement the axle of the driving wheel projects on both
sides and is fixed in two radial arms whose opposite ends are pivotted to the main
frame which can be moved about the axle to be raised or lowered in a circular
direction. One of these arms is formed quadrant shaped and provided with teeth
into which a pinion gears, said pinion being on a short shaft whose opposite end has a
worm wheel geared into by a worm on the end of a spindle having a crank handle
at its opposite end.
The operation of lifting the frame is as follows:-
The worm being turned by the crank handle on its spindle causes the worm wheel
to rotate and with it the pinion on the cross shaft which pinion being in gear with the
teeth of the quadrant causes it to rotate and the frame to be raised or lowered as
desired.
According to the second improvement the lower drive roller of the elevator has on
its end which projects through the front of the machine a feather and carries a couple
of different speed pinions either of which can be drawn on to the feather for com-
municating motion to a wheel fitted on a bracket. This wheel has on its outer face a
ring of mitre teeth into which a bevil wheel on the lower end of a divided shaft
engages, the shafts being connected by an universal joint. This shaft has a loose fitting

page_text: collar on it provided with teeth as a pinion to gear with the wheel on the end of the
reel shaft. This pinion and wheel are fitted in a screen the lower portion of which
forms a bearing for the pinion. The upper part of the divided shaft through the
universal joint is capable of being set or shifted to any angle according to the desired
position of the reel this being determined by the crop to be cut, the reel having the
usual lever mechanism attached to it for that purpose.
The reel pinion has a free movement up and down the shaft to suit the height at
which the reel has to work and it can be adjusted and set by a foot and a hand lever as
required.
According to the third improvement the "Butter" has an eye attached to its loose
end and one end of a rod engages in this eye loosely the opposite end of the rod being
similarly engaged in an eye of a bent arm projecting from the machine frame so that
as the rotating disc carries the inner end of the "Butter" round for knocking up the
straws the opposite end has a to and fro motion on or above the gathering board which
is governed by the rod and bent arm with freedom and without friction.

I WILLIAM MCINTYRE CRANSTON of 36, Worship Street, Finsbury, Middlesex,
Agricultural Engineer, do hereby declare the nature of this invention which has been
communicated to me from abroad by The Walter A. Wood Mowing and Reaping
Machine Company, of Hoosick Falls, New York, United States of America, 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 certain detail improvements in Harvesters.
1. In a special method or arrangement of appliances by which the machine at one
side can be lifted bodily upon the main or drive wheel.
2. In a particular combination of gear with varying speed motion for operating the
reel from the lower drive roller of the elevator.
3. In a novel arrangement of appliances for operating the "Butter."
According to the first improvement which is represented at figures 1, 2 and 3
(sheet 1) of the annexed drawings, the axle a of the driving wheel projects on both
sides and is fixed in two radial arms c, d, whose opposite ends are pivotted to the main
frame e which can be moved about the axle a to be raised or lowered in a circular
direction. One of these arms c is formed quadrant shaped and is provided with teeth
into which a pinion gears, said pinion being on a short shaft whose opposite end
has a worm wheel geared into by a worm i on the end of a spindle this having a
crank handle k at its opposite end.
The operation for lifting the frame is as follows:-The worm being turned by the
crank handle on its spindle causes the worm wheel to rotate and with it the
pinion on the cross shaft g, which pinion being in gear with the teeth of the
quadrant e causes it to rotate and the frame e to be raised or lowered as desired.
According to the second improvement which is represented at Figure 4 sheet 2, the
lower drive roller of the elevator has on its end which projects through the front
of the machine a feather m carrying two different speed pinions n, p, either of which
can be drawn by means of the spring lever and fork p', on to the feather on the shaft m
for communicating motion to the wheel y fitted on a bracket r. This wheel has
on its outer face a ring of mitre teeth s into which a bevel wheel on the lower end
of a divided shaft u engages, the shafts being connected by an universal joint . This
shaft u has a loose fitting collar we on it provided with teeth as a pinion to gear with
the wheel on the end of the reel shaft y. The pinion and wheel are fitted in a
screen the lower portion of which forms a bearing for the pinion w. The upper part
of the divided shaft u through the universal joint is capable of being set or shifted
to any angle according to the desired position of the reel, this being determined by
the crop to be cut, the reel having the usual lever mechanism attached to it for that
purpose.
The reel pinion has a free movement up and down the shaft u to suit the height

page_text: at which the reel has to work and it can be adjusted and set by a foot and a hand lever
as required.
Figure 5 is an enlarged sectional view of the two different speed pinions n, p, on the
end of lower elevator roller 1.
According to the third improvement shown at Figures 6 and 7 the "Butter" A has
an eye B attached to its loose end and one end of a rod C engages in this eye loosely,
the opposite end of the rod C being similarly engaged in an eye D of a bent arm E
projecting from the machine frame e so that as the rotating disc F carries the inner
end of the "Butter" round for knocking up the straws, the opposite end has a to and
fro motion on or above the gathering board G which motion is governed by the rod C
and bent arm E with freedom and without friction.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is
1. The particular arrangement of appliances by which the frame of the machine is
carried by the axle of the main drive wheel and capable of being raised and lowered
from said axle by quadrant gear through the intermediation of worm gear as set forth
with reference to Figures 1, 2 and 3 of the annexed drawings.
2. The appliances shown at Figures 4 and 5 of the annexed drawings, whereby the
speed of the reel can be varied and operated from the lower drive roller of the
elevator as set forth.

3. The loosely fitted rod C, Figures 6 and 7, by which the tail end of the "Butter
is governed in its motion from a rod fixed to the machine as and for the purpose
described.
