a com-
This invention relates to that type of harvesters commonly termed one wheel
that is having at the inner or stubble end, a main or driving wheel and at the
opposite or outer end a grain wheel or caster with a platform usually segmental,
but sometimes rectangular supported between the two and a sweep or other rake
to clear the gavels therefrom.
And it consists in improved means for raising and lowering said platform, in
improved means for tipping said platform upon its supporting or carrying wheels
to change the angle of the knives to the standing grain or to pick up-lodged grain;
in suspending said platform at its inner end from a supporting bar pivoted to the
draft-tongue and raising and lowering said bar by means of a link from a lever
pivoted to a bracket sleeved upon the main axle and connected with the prime
pinion shaft; in suspending the inner end of said platform from a supporting bar
pivoted to the draft-tongue and making the front connection with said bar by
ineans of a link from a lever pivoted thereon, latching into a segment whereby the
front of the platform may be raised and lowered towards and from said bar, to tip
it relatively to its carrying wheels; in mounting the rear of the platform upon a
rock-shaft running longitudinally therebeneath and provided at its outer end with
D

end with a like arm parallel or nearly parallel with the first, connected by means
of a link with the main axle or a sleeve thereon, so that as the inner end of the
platform is raised or lowered the outer end shall move simultaneously therewith
and preservo its parallelism; in the combination of a main or driving wheel, a
main axle, a bracket sleeved thereon and connected by a rearwardly extending
radius arm with the prime pinion shaft journalled in brackets froin the platform,
a cranked shaft running longitudinally beneath the platform and bearing in the
arm at its outer end the grain wheel and link connected from the arm at its inner
end to the main axle, a supporting bar pivoted at its front end to the draft-tongue
and at its rear end sliding in a keeper at the rear of the platform, a lever pivoted
to a front extension of the bracket upon the main axle, a rack upon said extension
into which a dog from the lever takes, to hold it in its adjusted position, a link or
other connection between an arm of said lever and the supporting bar, a second
lever pivoted to a bracket upon said supporting bar and latching into the rack in
said bracket, and a link or other connection between the arm of this lover and the
front of the platform whereby the platform may be raised and lowered or tipped
at will; in the combination of a main or driving wheel, a platform, a grain wheel
at the outer end of said platform supported upon an arm from a cranked shaft
running longitudinally therebeneath, a link connecting a second arm from said
crank shaft at its inner end with the main axle, a draft-tongue hinged to the front

to the draft-tongue and at its rear end sliding in a keeper at the rear of the
platform, a bracket mounted upon the main axle inside the wheel connected by
means of a rearwardly extending radius arm with the prime pinion shaft, and by
a second forwardly extending arin affording a pivot and rack for a lever linked
with the supporting bar, and a second lever pivoted upon said supporting bar,
latching into a rack therefrom and connected with the front of the platform; in an
improved clutch or backing latchet so constructed that the dog or pawl may
be thrown and locked out of engagement; in combining with the dog or pawl
in a clutch or backing ratchet for harvesters, a cam-button whereby it may be
thrown out of engagement and locked against return; in the combination of a
main wheel, an axle keyed thereto and turning therewith a bracket sleeved upon
said axle inside of the main wheel and connected by a rearwardly extending radius
arm, with the prime pinion shaft mounted in bearings upon the platform, a main
gear-wheel upon said axle inside of the bracket and a clutch or backing ratchet
between said wheel and the axle, and in the various other combinations and details
of construction hereinafter set forth.
To the front of the platform is hinged the rear-end of a draft-tongue connected
also by a hound with the inside shoe or divider.
Pivoted to this draft-tongue either by the same bolt securing the front end
of the hound or at another suitable point, is a strong bar hereinafter called the
supporting-bar or frame-bar which runs back to the rear inner corner of the
platform or thereabouts, and is there confined by a keeper, in which it is allowed
to play longitudinally, and, to compensate for the tipping of the platforin, it has
its under surface at this end beveled.
Another bar or brace rigid with the seat support and foot-rest sleeved to the
stubble end of the axle, is brought to the tongue at the pivotal point of the frame-
bar, and is there confined with capacity of longitudinal play in a keeper also
preferably secured by the pivot-bolt of the hound and having a pendulum movement,
so as to support the seat in its proper position during the vertical and tipping
adjustments of the platform
A bracket casting is sleeved to the axlo inside the main wheel and provided
with a rearwardly extending arm sleeved, to the prime pinion shaft supported in
standards at the rear inner corner of the platform above or adjacent to the keeper

page_text: for the frame-bar, said arm thus serving as a radius bar to keep the prime pinion
in mesh with the main-gear mounted upon the axle outside of the bracket casting.
In front of the axlo the casting is vertically flattened and enlarged to form a
segment rack with its teeth preferably set ratchet wise for the raising lowering
and supporting lever which lover is pivoted to the casting concentric with said
rack and by means of a link depending from its crank arm or off set is connected
with the frame-bar at a point over the front part of the platform, thus serving
to support said frame-bar from the axle, and through it the end of the platform.
A second lever is pivoted to a segment casting bolted to the frame-bar a little
to the rear of the tongue-joint and by means of a link connecting its arm with
said joint or with the platform serves to raise and lower the front of the platforin
or to hold it in fixed relation to the frame-bar. Both levers are provided with
hand pieces and links controlling latches which take into the racks upon their
respective segments, and hold them in any given adjustment.
It will be understood that instead of these link-connections between the lever-
arms and the bodies which they support, chains or other suitable instrumentalities
may be employed, the links however are preferable in this that they hold said
bodies rigidly to their work, and prevent wobbling or jumping
Journalled in hangers beneath the platform is a shaft parallel with the finger-
bar, but set sufficiently back therefrom according to the depth of the platform to
serve its purpose. At the grain end this shaft has a crank or arm forming a
support for the grain or caster wheel and at its inner end near the main wheel
another arm, at a slight angle to the former for more effective leverage but
extending in the same direction, that is forward, and directly connected by a link
with the main axle-said link being sleeved to the axle so as to swing thereabout-
the second arin however, being somewhat shorter than the grain-wheel support so
that as the platforın is raised and lowered in reference to the axis of the main-
wheel the relative movement of the grain-wheel, controlled by the link from said
axis shall keep pace with that of the main wheel and the grain end of the platform
rise and fall parallel with the stubble end.
Now supposing the tipping lever to be set at any given adjustment, the front
end of the platform will be held in fixed relation to the frame-bar immediately
above and if the raising and lowering lever is manipulated in the appropriate
direction this frame-bar will lift the platform concurrently in front and rear
preserving its fore and aft parallelism, meanwhile as the main wheel must relatively
sink it will operate the rock shaft through its link connection with the inner aria
thereof and will move the grain-wheel down a corresponding distance so as to
preserve the end wise parallelism of the platform to its original position.
But supposing that it is desired to tip the platform upon a given vortical
adjustment, the raising and lowering lever will remain untouched supporting the
frane-bar, the rear of the platform and the tipping lever at their fixed height and
the latter lever will be moved upon its pivot so as to raise the front of the platform
or to lower it as may be desired. Either of theso adjusting movements will cause
a flexion of the draft-tongue upon its pivots, which will be compensated for by the
play of the frame-bar in its keeper, and as to the seat by the play of the arm
therefrom in the pendulum or other guide upon the tongue while as before inti-
nated the prime-pinion will be kept in mesh with the main gear by the action of
the radius-arm from the bracket, sleeved upon the main axlo and supporting the
raising and lowering lever.
It is evident that the frame-bar instead of being pivoted to the draft-tongue at
the front-end and playing in a keeper on the platform at the rear end, can with the
same effect be pivoted to the platform, or a bracket therefrom at the rear end and
play in a keeper on the draft-tongue at the front end, It is also evident that the
bevel on the rear end of the frame-bar can be omitted and some other compensating
device adopted as a slot in the platform or a raised keeper having rollors between
which the bar plays.
The main-gear may be fixed to the main wheel as in many harvesters now in

page_text: use in which case the latter wheel may run loose upon the axle, but as already
stated it is preferable that it shall be keyed fast to said axle and mount the main-
gear loosely on the axle connecting it therewith by a backing ratchet so that it
shall be driven in one direction only.
In order to permit this one way clutch or backing ratchet to be thrown entirely
out of action for transporting the machine, it is constructed with a disc pinned to
the axle on the inner side of the gear wheel, completely closing the ratchet chamber
therein so as to shield the inechanism within it. From the hub of this disc within
the chamber is an offset having a cylindriform recess with an opening or throatway
to one side. Within this recess is set the cylindrical head of the dog having its 1
tongue passing through and playing within the lateral throat or opening. The
head is socketed to receive the coil of a spring one end of which bears against the
´hub and the other against the tongue of the dog to force it out into engagement
with the teeth of the ratchet. Near the point of the dog an oblong slot is cut
through the covering disc on an arc concentric with the axis of the dog. A latch 1
'or cam button is placed exteriorly to the disc with its spindle entering through
the slot to a pivotal seat in the end of the dog and its cam or latch resting upon
the face of said disc, or else the spindle being pinned to the dog and the pivotal
connection being immediately between the latch and the outer end of said
spindle.
When the dog is in engagement the spindle of the button will be at one end of
the slot. In order to disengage it the button is pressed back towards the other end
and then turned until its cam or latch enters into a recess of suitable shape formed
within a web or rib on the face of the covering disc where it will be kept by the
pressure of the spring until intentionally released by turning the button when the
dog will be again forced into engagement.
Upon the outer face of the gear-wheel are lugs to which is bolted the swivelling
member or gimbal of a telescoping tumbling shaft driving the rake-cam located at
the inner front corner of the platform.
The prime-pinion shaft mounted as above mentioned in bearings on the rear of
the platform with its pinion meshing with said gear and kept in engagement
therewith by the radius arm of the bracket casting on the main axle, is provided
immediately beyond the pinion with a bevelled gear wheel which drives a bevelled
pinion fast to the end of the crank-shaft running transversely along the inner end
of the platform and beneath the tumbling shaft until its wrist-pin is brought in
proper relation to the heel of the cutter bar.
Thus the main gear driven immediately from the main axle in the forward move-
ment of the machine drives the rake by direct tumbling shaft connection, and the
cutter crank shaft by means of the prime pinion and single set of mitre gears, and
on the other hand when from any reason thrown out of engagement with said axle
causes both rake and cutter-bar to stand at rest.
To economise space and bring the platform close to the inner edge of the main
wheel the latter is made flaring or dishing inwardly and the bracket with its
radius arm suitably bent and formed to coincide with said dish shape thus enabling
the end of the prime pinion shaft to be set close to or within the main wheel rim
The main gear is also dished and the ears for the attachment of the tumbling-shaft
formed upon the dished face, close to the axle or supporting shaft.

means of a link from a lever pivoted to a bracket sleeved upon the main axle and
connected with the prime pinion shaft, in suspending the inner end of said platform
from a supporting-bar pivoted to the draft-tongue and making the front connection
with said bar by means of a link from a léver pivoted to a bracket sleeved upon
the main axle and connected with the prime pinion shaft, in suspending.the inner
end of said platform from a supporting-bar pivoted to the draft-tongue and
making the front connection with said bar by means of a link from a lever
pivoted thereon latching into a segment, whereby the front of the platform may be
raised and lowered toward and from said bar to tip it relatively to its carrying
wheels, in mounting the rear of the platform upon a rock shaft running
longitudinally therebeneath, and provided at its outer end with a forwardly
extending arm, in which is pivoted the grain-wheel, and at its inner end with a
like arm parallel or nearly parallel with the first, connected by means of a link
with the main axle or a sleeve thereon, so that as the inner end of the platform is
raised or lowered, the outer end shall move simultaneously therewith and preserve
its parallelism; in the combination of a main or driving wheel, a main axle, a
bracket sleeved thereon and connected by a rearwardly-extending radius-arm with
the prime pinion shaft journalled in brackets from the platform, a cranked shaft
running longitudinally beneath the platform, and bearing in the arm at its outer
end the grain-wheel and link connected from the arm at its inner end to the main
axle, a supporting bar pivoted at its front end to the draft tongue and at its rear
end sliding in a keeper at the rear of the platform, a lever pivoted to a front:

Figs 7 and 8 are details of such clutch with the dog out of engagement.
A is the main wheel, for the purpose of the present gearing keyed fast to its
axle a, but, if demanded by the nature of other gearing substituted therefor in the
machine, allowed to turn loosely on said axle; and A' is the seat supported at the
stubble side of said wheel upon a standard rising from a bracket or casting sleeved
upon the axle.
B is the platform, of any suitable shape required by the action of the raking
mechanism or by the naturo of the harvester. To the front of this platform
is hinged the rear end of the draft-tongue C, connected also by a hound c with the
inside shoe or divider pivoted to this draft-tongue, either by the same bolt securing
the front end of the hound or at another suitable point, is a strong bar, D,
hereinafter called the "supporting-bar" or frame-bar, which runs back to the rear
inner corner of the platform or thereabouts, and is there confined by a keeper, d, in
which it is allowed to play longitudinally, and to compensate for the tipping of
the platform it has its under surface at this end beveled. Another bar or brace, E,
rigid with the seat support and foot-rest E' sleeved to the stubble end of the axle,
is brought to the tongue at the pivoted point of the frame-bar, and is there
confined, with capacity of longitudinal play, in a keeper e, also preferably secured
by the pivot-bolt of the hound and having a pendulum movement, so as to support
the seat in its proper position during the vertical and tipping adjustments of the
platform.
A bracket casting, F, is sleeved to the axle inside the main wheel and provided
with a rearwardly extending arm f secured to the prime pinion-shaft f' supported
in standards ƒ³ at the rear inner corner of the platform above or adjacent to the
keeper for the frame-bar, said arm thus serving as a radius-bar to keep the prime
pinion in mesh with the main gear G mounted upon the axle outside of the
bracket-casting. In front of the axle the casting is vertically flattened and
enlarged to form a. segment-rack with its teeth preferably set ratchet-wise for
the raising lowering and supporting lever H, which lever is pivoted to the casting
at h¹ concentric with said rack, and by means of a link 2 depending from its
crank-arm or off set h³ is connected with the frame-bar at a point over the front
part of the platform, thus serving to support said frame-bar from the axle, and

page_text: through it the rear end of the platform. A second lever I is pivoted to a segment-
casting i bolted to the frame-bar a little to the rear of the tongue joint, and, by
means of a link i connecting its arm with said joint or with the platform,
serves to raise and lower the front of the platform or to hold it in fixed relation
to the frame-bar. Both levers are provided with hand-pieces and links, controlling
latches which take into the racks upon their respective segments and hold them in
any given adjustment.
It will be understood that instead of these link-connections between the lever-
arms and the bodies which they support, chains or other suitable instrumentalities
may be employed. The links, however, are preferable in this, that they hold said
bodies rigidly to their work and prevent wobbling or jumping.
Journalled in hangers beneath the platform is a shaft K parallel with the finger-
bar, but set sufficiently back therefrom, according to the depth of the platforin, to
serve its purpose. At the grain end this shaft has a crank or arm k forming a
support for the caster-wheel, and at its inner end near the main wheel another
arin, at a slight angle to the former, for more effective leverage, but extending
in the same direction, that is-forward, and directly connected by a link k³, with
the main axle, said link being sleeved to the axle, so as to swing thereabout, the
second arm, however, being somewhat shorter than the grain-wheel support, so that
as the platform is raised and lowered in reference to the axis of the main wheel,
the relative movement of the grain wheel controlled by the link from said axis,
shall keep pace with that of the main wheel, and the grain end of the platform
rise and fall parallel with the stubble end.
Now, supposing the tipping-lever I, to be set at any given adjustment, the front
end of the platform will be held in fixed relation to the frame-bar immediately
above, and if the raising and lowering lever H, is manipulated in the appropriato
direction, this. frame-bar will lift the platform concurrently in front and rear,
preserving its fore and aft parallelism. Meanwhile as the main wheel must
relatively sink, it will operate the rock-shaft through its link connection with the
inner arm thereof, and will move the grain-wheel down a corresponding distance
so as to preserve the endwise parallelisin of the platform to its original position.
But, supposing that it is desired to tip the platform upon a given vertical
adjustment, the raising and lowering lever H will remain untouched, supporting
the frame bar, the rear of the platform and the tipping lever I at their fixed height,
and the latter lever will be moved upon its pivot, so as to raise the front of the
platform or to lower it, as may be desired. Either of these adjusting movements
will cause a flexion of the draft-tongue upon its pivots, which will be compensated
for by the play of the frame-bar in its keeper, and, as to the seat by the play of'
the arm therefrom in the pendulum or other guide upon the tongue, while as before
intimated, the prime pinion will be kept in mesh with the main gear by the action
of the radius arm from the bracket sleeved upon the main axle and supporting the
raising and lowering lever.
It is evident that the frame-bar instead of being pivoted to the draft-tongue
at the front end and playing in a keeper on the platform at the rear end, can, with
the same effect, be pivoted to the platform or a bracket therefrom at the rear end
and play in a keeper on the draft-tongue at the front end. Therefore when-
ever it is qualified in the claims hereinafter as secured in the former way, it is to
be understood that the latter is included as an equivalent. It is also evident that
the bevel on the rear end of the frame-bar can be omitted and some other
compensatory device adopted as a slot in the platform or a raised keeper baving
rollers between which the bar plays.
The main gear may be fixed to the main wheel, as in many harvesters now in
use, in which case the latter wheel may run loose upon the axle; but, as already
stated, I prefer that the main wheel shall be keyed fast to said axle, and mount
the main gear G loosely on the axle, connecting it therewith by a backing-
ratchet, L, so that it shall be driven in one direction only. In order to permit
this one-way clutch or backing-ratchet to be thrown entirely out of action for

page_text: transporting the machine, it is constructed as shown in Figs 5 and 6, that is a
disc, M, is pinned to the axle on the inner side of the gear-wheel, completely
closing the ratchet-chamber therein, so as to shield the mechanism within it.
From the hub of this disc, within the chamber, is an offset m having a cylindriform
recess m³, with an opening to one side. Within this recess is set the cylindrical
head of the dog N having its tongue passing through and playing within the
lateral throat or opening. The head is socketed to receive the coil of a spring n²,
one end of which bears against the hub and the other against the tongue of the dog
to force it into engagement with the teeth of the ratchet g². Near the point of the
dog an oblong slot m², is cut through the covering-disc on an arc concentric with
the axis of the dog. A cam button O, is placed exteriorly to the disc, with its
spindle o entering through the slot to a pivotal seat in the end of the dog, and its
cam or latch o' resting upon the face of said disc, or else the spindle being pinned
to the dog and the pivotal connection being immediately between the latch and
the outer end of said spindle. When the dog is in engagement the spindle of the
button will be at one end of the slot. In order to disengage it the button is
pressed backward toward the other end, and then turned until its cam or latch
enters into a recess o³, of suitable shape, formed within a web or rib m³, on the
face of the covering disc, where it will be kept by the pressure of the spring until
intentionally released by turning the button, when the dog will be again forced
into engagement.
Upon the outer face of the gear-wheel are lugs p, to which is bolted the
swivelling member or gimbal of a telescoping tumbling-shaft P driving the rake
located at the inner front corner of the platform. The prime pinion-shaft mounted
as above mentioned in bearings on the rear of the platform, with its pinion
meshing with said gear and kept in engagement therewith by the radius-arm of
the bracket-casting on the main axle, carries immediately beyond, and integral
with the pinion a beveled gear-wheel, 7, which drives a beveled pinion r¹, fast to
the end of the crank shaft R, running transversely along the inner end of the
platform and beneath the tumbling-shaft until its wrist-pin is brought in proper
relation to the heel of the cutter-bar. Thus the main gear, driven immediately
from the main axle in the forward movement of the machine, drives the rake. by
direct tumbling-shaft connection, and the cutter crank shaft by means of the prime
pinion and single set of bevel gears, and, on the other hand, when from any
reason thrown out of action with said axle, causes both rake and cutter-bar to stand
at rest.
To economisc space and bring the platform close to the inner edge of the main-
wheel, the latter is made flaring or dishing inwardly, and the bracket, with its
radius-arm, suitably bent and formed to coincide with said dish-shape, thus
enabling the end of the prime pinion-shaft to be set close to or within the main
wheel rim. The main gear is also dished, and the cars for the attachment of the
tumbling-shaft formed upon the dished face close to the axle or supporting-shaft.
