Specification Accepted, 19th Apr., 1887.

page_text: The general structure is, that the wheel frame is pivoted at the centre of the drive
wheel, and rocks over that centre, and has the platform frame pivoted to it
eccentrically to the wheel and rocking over such eccentric pivot.
The wheel frame comprises the drive wheel axle A; the crank arm A¹, rigid with
such axle; the crank wrist A², on the crank arm; the lever arm A* extending from
the junction of the crank arm A', with the axle, upward, and being in the form of a
segment about the axis of the crank wrist A2; the brace arm A³ which extends from
the end of the crank arm A, to the end of the lever arm A. At the junction of the
arm A with the brace A', the wheel frame has the lug at, which extends in the
general direction of the brace arm A, and when the several parts are separately
made and bolted together, may be a continuation of said brace, though in its
mechanical function it is properly a continuation of the arm A¹.
It will be seen that the wheel frame comprises a bell-crank lever, composed of the
arms A¹, and A*; the fulcrum of said lever being at the axis of the drive wheel.
Also, that it comprises a crank shaft, crank arın, and crank wrist-viz. the axle, the
arm A, and the wrist A².
The part A is a segment about the centre of the crank wrist A³, and for a purpose
hereinafter stated, it has the teeth a forming a segment rack on the grainward
face.
B is the drive wheel and B¹ is the main driving gear rim rigid with said wheel.
The crank wrist A², is tubular, and through it passes the main driving pinion b²,
having on its outer end the main driving pinion B2, meshing exteriorly with the main
driving gear rim B'.
The platform frame comprises the plank C, and the brackets C¹ and C, secured
firmly thereto at the stubble end. The bracket C has the journal box C, by which
the platform frame is pivoted on the crank wrist A2 of the wheel frame. This box
has certain peculiarities for another purpose, which will be hereinafter explained.
Said bracket C has other journal bearings for various parts of gearing which will
be fully described in connection with the operating mechanism.
The bracket C, comprises also, the seginental arm C2, at the forward end, extended
up from the plank C, in an are about the axis of the crank wrist journal bearing and
main pinion shaft: said segmental arm C, is provided with flanges which embrace
and guide the segmental lever arm A, of the wheel frame, and with lugs ², c², in
which is journalled a worm shaft C, having between the lugs the worm c, engaging
in the segment rack teeth a0; said worm shaft is extended up above said bearings,
and at the upper end it is provided with the crank handle C by which it may be
_rotated by the driver.
D is the tongue. It is provided at the rear end with the journal box D', which
is secured to it on the under side, and the journal box (20, intermediate to its ends,
is hollowed and has the upper part cut away, as seen in Figs. 8 and 9, in order
that it may receive the box D', in the manner also illustrated in said Figures. Said
box D', is tubular to allow the crank wrist A³, to be passed through it, and it is
thereby pivoted on said crank wrist and also in the box C; being thus pivoted both
to the wheel frame, and to the platform frame.
To the under side of the pole, forward of the wheel, is secured the bracket D³, and to
said bracket at its lower ends is pivoted the jointed lever comprising the parts D³
and D, pivoted together at d³, which is the centre of a notched segment Do, in which
the part D³, terminates above. The part D*, has suitably mounted on it, the sliding
bar D, which terminates at the lower end in a tooth d, which engages the notches
of the segment D, and a spring D₁, suitably stopped between the parts D' and D40,
tends to hold the tooth in such engagement.
To the part D³, is connected the forked brace-link D, which at the other end is
connected to the platform frame-most conveniently to the plank C, as illustrated in
Fig. 4.
The part D*, is connected to the wheel frame by means of the chain Do, which is
connected to the said lever D₁, at the pin d, above the segment D, and is hooked
into the lug at. This connection may be considered as made with the lever arm A', of

page_text: the wheel frame, since in operation the strain applied to said chain, takes effect upon
the wheel frame as applied to the end of the lever arm A*. The lever D, is also con-
nected by the drought chain D', to the double tree, so that the power applied by the
horses is exerted through said chain D', upon the lever D₁, and then upon the lever
arm A. The two chains D, D', are conveniently made as one continuous chain, and
certain adjustment of the jointed levers D³, D', with reference to the wheel frame, may
be effected by changing from link to link, the connection of the chain D', to the
pin №40
The operation of the devices already described in raising and lowering the platform
frame at its stubble end, is as follows:-
The screw shaft, being rotated by means of the crank handle C, the worm c¹ engages
the teeth of the segment rack teeth a10, on the lever arm A, of the wheel frame, causes
the platform frame of which the arm C having the bearings of the screw shaft C,
forms a part to rock over the pivot, viz. The wrist A2 of the wheel frame. Said
platform frame being connected by the chain D, to a jointed lever D³, D₁, to the
tongue D, and the tongue being connected to the wheel frame, the raising or lowering
of the main frame, by rocking it over said pivot, causes the pole to rock said wheel
frame over the drive wheel axle A. Both said rocking movements being in the same
direction, that is, being either, both upward, or both downward; it is evident that if
the tongue were lifted or lowered bodily by the described movement of the platform
frame, the tilt of the machine would not be at all effected by the described raising or
lowering movement; but such is not the case, the tongue having one fixed point, viz.,
where it rests on the neck-yoke, which is upheld by the horses. The effect, therefore,
of the vertical adjustment by the means above described, would be to swing the
platform frame up or down through an are whose centre is the bearing of the tongue
on the neck yoke: such movement would slightly tilt or change the inclination of said
frame, but for the automatic correction which will now be described: Raising the
machine tends to tilt it forward or down, and lowering it tends to tilt it backward or
up; but raising the machine tends to throw the lug a forward, and the draft being
on the chain D, D7, the forward movement of the lug causes or allows the jointed
lever D, D, moving as integral,-being locked together by the engagement of the
tooth, in the segment 10,-to rock forward over the pivot on the bracket D².
Such forward movement of said jointed bar, causes the link D6, to draw the lower
forward edge of the platform frame forward and upward; but this is to tilt the
machine up.
Similarly the lowering of the platform frame which tends directly to tilt it up,
operates by means of the connection described to correct said tendency and tilt it
down an equal amount, so that practically no change of tilt is caused by the raising
and lowering. The platform frame and the wheel frame being rigidly locked together
as one by the engagement of the screw c, in the rack teeth of the segment A, the
inclination of the platform may be adjusted as described independently of the raising
and lowering, by means of the lever D. Both handles and d", being grasped, and
the slide bar being pulled up to disengage its tooth d", from the segment D, the
lever D being rocked forward over its pivot, the pin passing through the chain D*,
becomes the actual pivot of its motion, and the joint at d³, moves rearward. The
lever D³ rocking over its pivot on the bracket D2, the link D recedes and the
machine is tilted down or forward. Rocking the lever D, backward, reverses the
above described action, and tilts the machine up or back.
The form of the raising and lowering screw shaft and its connection with the wheel
frame and platform frame may be modified as shown in Fig. 18 wherein the screw
shaft C is provided at its opposite ends with threads of opposite pitch and cl
respectively the former entering a threaded sleeve or nut (pivoted on the arm A
of the wheel frame, and the latter entering a similar but oppositely threaded sleeve or
nut C pivoted on the segment (2 of the platform frame. The first sleeve corresponds
in function to the segment rack teeth 10 and the latter sleeve to the bearing lugs c".
But by reason of the opposite threads and c¹ the rotation of the shaft produces a
double effect in changing the relation of the former and so permits the use of a smaller

page_text: shaft and threads of less pitch without diminishing the speed of raising and lowering.
The sleeves or nuts (2 and C2 should be pivoted to the frames respectively so that
they may accommodate themselves to the changing direction of the shaft as the frames
change their relative positions.
The draft being applied to the lever D, and that lever being connected by the
chain D to the lug a on the end of the lever arm A, of the wheel frame, the effect is
as if the draft chain were attached directly to the end of said lever arm. If it were so
attached the tendency of the draft applied through the draft chain would be to tip
forward "the entire harvester frame, comprising the wheel frame and the platform
frame locked rigidly together by the engagement of the worm c, and its rack teeth a*.
But such tendency would be resisted by the tongue, rigid with the frame and resting
in the neck-yoke upheld by the horses, and thereby holding the machine level and
, causing said tendency to tip forward to be converted into a tendency to lift the main
frame acting as a bell-crank lever, comprising, as hereinabove stated, the arms A
and A', rocking over the axle of the drive wheel, which constitutes the fulcrum, and
carrying the platform frame on the end of the horizontal arm, viz. on the crank
wrist A. The two arms of this bell-crank lever being approximately equal in length,
the drawing strain is made effective as a lifting power of equal amount.
The main driving pinion B2, being meshed with the main driving gear B', in the
rear thereof, the re-action between said gear and pinion also tends to lift the latter
and with it the platform frame in which the said pinion is journalled; the lifting
effect of this re-action, added to that above described, may be made sufficient to
approximately equal the weight of the platform frame, and all mechanism supported
thereby, and raised and lowered therewith, so that the worm is relieved of all strain
and friction while being operated to raise and lower the platform, except the fluctuating
margin of strain due to the variations in the resistance to travel and operation and
consequent variation in the drawing power required and exerted. The machine is
thereby rendered very promptly adjustable with very little effort on the part of the
operator.
E is the grain wheel. It is journalled on the wrist Ex, of the grain wheel lever
arm E', which is pivoted in the rear of the line of the sickle and finger bar, to the
bracket E¹, which is secured to the grain end of the plank C; said lever arm E³, is
adapted to vibrate through an are in front of its pivot and between the end of the
cutter bar and the standing grain; and it has rigid with it the segment E", whose
centre of curvature is the axis of the pivot E", of the lever arm E². For the purpose
of guiding said segment there is provided the segment guide e, integral with the
bracket E, which secures the divider E', to the base plank C. On said bracket there
is also journalled the guide pulley e³, for the chain E, which is secured to the upper
end of the segment E, and is guided on the flange e, passing thence around the
guide pulley e³, thence across along the finger bar, as illustrated, it passes under the
finger bar to the stubble side of the machine, then around the pulley e, at the lower
corner of the bracket C₁, thence up over the pulley e, at the upper end of the
segment arm (1, and thence down to the lower end of the segment A³, to which it is
secured at e.
The structure above described serves to transmit the raising and lowering movement
of the stubble side of the platform frame to the grain side thereof, and it operates for
that purpose in a manner obvious from the construction. The novelty of the structure
consists in pivoting the grain wheel lever arm in the rear of the line of the sickle, and
journalling the grain wheel thereon in such position that it vibrates past the end of
the sickle the line of thrust of the sickle being within the circumference of the
wheel whereby it becomes possible to extend the connecting chain directly from its
fastening at the grain wheel segment, to the guide pulley at the end of the finger bar,
and so across along the finger bar to the stubble side.
The operating mechanisin supported on the platform frame will now be described.
A little distance grainward from the inner or grainward end of the crank wrist A³,
of the wheel frame, the shaft 62, is provided with the clutch 60, of familiar construction,
by means of which said shaft communicates motion to the bevel gear wheel F, which

page_text: is journalled on it between the clutch and the end of the crank wrist; and said bevel
gear wheel communicates motion to two bevel pinions which mesh with it, viz., Fl which
is fixed on the shaft f, which is journalled in the bracket C, and drives the sickle and
the reel, and F, which is fixed on the shaft, which is also suitably journalled in the
bracket C, and communicates motion to the conveyor by means of the train of gearing
which comprises the gear wheel F, secured on the lower end of the shaft, the
intermediate or idle gear wheel F", journalled on a stud axle fixed in the plank C,
and the gear and sprocket wheel F, which is journalled on a stud axle fixed in
the said plank, and by means of the sprocket rim F2, operating the conveyor actuating
chain as will be more fully described hereafter.
The conveyor is adapted to receive the grain and accumulate it without allowing it
to fall prostrate; and for that purpose it comprises a frame supported on the rear part
of the plank C, and projecting upward and preferably slightly inclined toward the
rear, and conveying mechanism supported by and travelling around said frame, moving
stubbleward in front of said frame, where it engages and moves the grain, and returning
grainward at the rear. This conveyor frame and mechanism will now be described in
detail.
equal
G, G, are uprights secured at the lower end to the plank C. Their upper ends are
joined by the horizontal bar G¹. G2 is a board which also joins said uprights
intermediate to the plank C, and the top rail G¹. Its purpose, beside stiffening the
frame, will hereinafter appear. Both the top rail or bar G¹, and the board G2, extend
stubbleward beyond the inner upright G, almost to the vertical plane of the stud
axle, and to the end of the bar G is secured the block or bracket g', from which
depends vertically a stud axle 24, on which is journalled the sprocket wheel F24,
in size to the sprocket rim F2 of the wheel F. The two sprocket wheels F and F
are connected by the oblique shaft F" which is forked at the ends; said forks
and striding the heads of the stud axles and respectively, and their prongs f
and flo, entering the apertures 720, and 240, in the web of the sprocket wheels F2 and F
respectively. Said oblique shaft thus makes a universal joint with the said sprocket
wheels, whereby said shaft, although oblique to the plane of rotation of both said
wheels, nevertheless communicates rotary motion from the former to the latter. At
the opposite end of the conveyor, journalled upon the stud axles 126 and 27, the
former erected on the ledge C, and the latter depending from the block go, secured
to the upper frame bar G₁, are the idle sprocket wheels F28 and F27 respectively, the
former in the same horizontal plane with the sprocket wheel F23, and the latter in the
same horizontal plane with the sprocket wheel F. Around the wheels F23 and F26,
is the conveyor chain F; and around the wheels F24 and F27 is driven the chain F
Said chains are connected by the rods F³, pivoted to the links at intervals, in a manner
hereinafter explained in detail; and from said rods there are protruded the grain
carrying fingers projecting forward at different heights, overhanging the plank C,
which here constitutes a grain supporting ledge. In front of the rods F, at a short
distance only therefrom, so that the fingers F, protrude between them to a considerable
distance further forward, are arranged the horizontal strips F' F7 which may be
secured to any convenient portion of the harvester beyond the conveyor, at both ends.
To the upper end of the rods F, are secured the clips F50, having the tails, standing
approximately at right angles to the plane of the grain carrying fingers F, F1, F;
and to the under side of the upper frame bar G', is secured the rib or flange G, which
has its front edge a little to the rear of the front ply of the chain F, and forms a
track for the said tails, which resting upon it as the chains travel across the front
of the conveyor, cause the rods F³, to stand in a position with their grain carrying
fingers F, F, F, protruded rigidly forward over the ledge G. To the side of
upper
the upper frame bar G', at the discharge end, is fastened the block gl, extending
beyond the end of said bar G', and having the roller 913, journalled on the stud axle
on its lower side: said roller stands down into the track of the tails 10, at the end of
the rib Go, so that before the tails, run off said rib, they run against said roller,
which, being a little further forward than the lip, throws the tails further forward,
rocking the rods F, and thus giving to their grain carrying fingers a movement

page_text: The
forward just at the instant when the chains begin to turn around the sprocket wheels,
and thereby hastening the movement of the grain slightly in turning the curve.
block g¹¹ is produced toward the rear to form the cam g-the front corner being
flush with the roller g" and as the chain travels around the sprocket wheel, the
tail moving as does the chains-horizontally, rises relatively to the roller, and
slides up on it and then off of it onto the cams, slipping off the latter at its rear
corner and allowing the grain carrying fingers to withdraw from the grain longitudi-
nally in the direction of the return ply of the chain F. At the opposite end of
the conveyor, the blocks g10, serves as a cam to engage the tails 50, and throw the
fingers F into operative position as the chain passes around the sprocket wheel F".
The connection or pivoting of the rods F to the upper chain F4 is by means of
the loops or staples formed rigidly with links at intervals, and loosely encircling
the said rods below the clips F. The connection of the said rods with the lower
chain F, is made by means of the clips or links F30 which are employed in
order to afford also a means of securing the butt carrying fingers F³, so that they
may operate as hereinafter described. Said links F are pivoted to lugs, formed
on links at intervals, their said pivots being vertical so that said links swing in a
horizontal plane, and are adapted to fold back on the chain. Said links are preferably
made as illustrated, as of a plate folded to form three sides of a hollow parallelo
piped the two parallel sides being horizontal and the connecting side being vertical,
the upper horizontal side of each has an oblong slot, and the lower ends of the
rods are flattened and inserted through said slots. A convenient and simple means
of preventing the rods from escaping from said slots is to form a flange or hook f³,
on their flattened ends, and then hook them into the clips respectively before the
latter are secured to the chains.
To the clips F are secured the butt-carrying fingers F31 which are made of angle-
iron and rivetted on the lower and vertical sides of the clips F, and thus embrace
the latter in their angles respectively, which open forward-that is, in the direction
of travel of the chain F, the horizontal blade of the angle-iron lying upon the
ledge C, and the vertical blade standing up therefrom. In the return travel of
the chain in the rear of the conveyor, the butt-carrying fingers F31, lie parallel with
the chain, and run in the track C³, guarded by the flange c. The action of these
butt-carrying fingers is to gather and carry the butts of the grain, which, standing on
their horizontal blades, hold them down on the ledge C, and so prevent the grain from
being drawn under them. The grain is thus not only pushed forward, but is positively
carried toward the discharge end of the conveyor.
The rods F are secured to the chains F and F so as to stand inclined-the lower
end foremost as seen in Fig. 1-From this result two advantages; 1st-The grain
leans slightly, to rest against the carrying fingers F, F, F, and is less liable to fall
forward prostrate on the ledge; 2nd-The upper end carrying the clip F whose
tail holds the rods with their fingers in operative position, passes around the sprocket
wheel a little later than the lower end, which carries the butt carrying fingers, so that
said butt-carrying fingers travel almost entirely around the sprocket wheel F24, before
the tail fo, slips off the cam g at the top, and by this means the butts of the grain
may be effectually delivered within reach of whatever gavelling or binding mechanisın
may be located at the discharge end of the conveyor. It will be observed that in order
to carry the butts as far as they are carried by this arrangement, if the rods F were
not leaned, as described, the upper end would be fully in the rear of the sprocket
wheel F, before the tail would be allowed to leave the cam, and that at that point its
own motion would not clear it-there being no change in its direction after that
point and some positively actuated device would be necessary in order to effect the
release of the tail from the cam. At the stubble end of the conveyor is located the
receptacle bounded at the bottom by the floor L, which covers the conveyor driving
train, and at the front and stubbleward side by the upright or slightly inclined wall L.
Said wall begins in front of the conveyor at a line grainward from its delivery end
thus slightly overlapping it. Thence it curves around rearward and stubbleward'
crossing the vertical plane of the conveyor at some distance from its delivery end'

page_text: between it and the drive wheel, tending to deflect the grain from the course in which
it is delivered by the conveyor-which is about at right angles to the vertical plane of
the drive wheel to a course which shall cause it to be discharged rearward, either to
the ground, or into a binder, if one is attached.
In order to keep the grain from falling prostrate as it is carried around the end of
the conveyor in this receptacle there are secured to this wall L', the spring fingers or
arms L which stand horizontally across the receptacle between the horizontal planes
of the carrying fingers F, F, F, and serve to keep the grain in the grasp of said
carrying fingers until it is stripped off them by the strips FF'.
The shaft journalled as stated, in the bracket C, has at the forward end, the
crank, which drives the sickle H, and intermediate its bearings in the bracket C³,
it has the worm f", which engages the spur wheel J, on the lower end of the shaft ;,
which is journalled in the bracket C₁, and extends obliquely upward, forward and
grainward through the whole length of the sleeve or arm C, of the bracket C¹, and
protruding therefrom at the upper end, has secured to it, the collar J', having the
ears, between which are pivoted the reel clips J' which are in the form of bell
crank levers comprising the arms J, and J", forming an angle, and near said angle
the clips are pivoted as described, to the lugs or ears j³.
To the upper-inner-end of the bracket ₁, at the end of the sleeve or arm (10, is
secured the cam C, which is of the familiar construction employed in reel rakes, and
said cam guides the arms J30, of the reel clips J2, said arm having anti-friction rolls 20,
adapted to said cam. The arms J21 have the sockets, to receive the reel arms J³,
which are secured in said sockets by the set screws ³. Said arms and sockets are made
cylindrical for a purpose hereinafter stated. To the arms J³, are secured the reel
bats J said arms are preferably shaped as illustrated, viz-extending from the
socket, a short distance J, in the direction of said socket, then a short distance J³1,
at about right angles to said direction, and the remainder J, of their length in a
direction about parallel with their first portion. The bats J, are secured on the said
outer portion J2, and in any convenient manner made adjustable thereabout, for a
purpose hereinafter explained.
The divider consists of the lower bar K, secured to the grain end of the plank C
and the upper bar K₁ secured to said lower bar at the forward end, and to the upper
end of the inner upright post G. The bar K' is made to stand inclined, with its upper
edge stubbleward, to adapt it to co-operate with the reel in a manner and for a purpose
hereinafter explained.
but
The operation of the above described mechanism will, for the most part, be obvious,
may
be more fully understood by the following:-
The reel bats, receiving their direction by the guiding action of the cam C follow
a course which may be understood by comparison of figures, and wherein the dotted
lines n, n, n, indicate the projection upon the plane of view, of the path of a point in
said reel bats: said course may be described thus, the bat enters the standing grain
with a downward and rearward movement, the direction of the bar being inclined
upward from heel to point. It swings downward and rearward, and becomes about
horizontal as it passes over the sickle, and thence moves upward and slightly rearward,
following the slope of the conveyor frame, the point rising faster than the heel, so
that it stands sloping obliquely upward to the point somewhat above the middle of the
height of the conveyor frame; it diverges from it rapidly, swinging back over its
course (or forward with reference to the travel of the machine) and reaches its initial
position. As it sweeps down toward the sickle, the point of the bat passes under the
overhanging inclined har K² of the divider, and thus gathers with certainty all the
grain enclosed by the divider, and is prevented from gathering any grain not so
enclosed.
As the hat passes over the sickle it forces the grain severed thereby, directly back
against the conveyor, where it is laid between the carrying teeth of the endless
conveyor chains and by them retained in its approximately vertical position while
being carried on end toward the receptacle. The bat, by continuing its course upward
from the sickle in direction approximately parallel with the conveyor, assists in

page_text: retaining the grain thereon, and the bats are so arranged that before one has withdrawn
from the vicinity of the conveyor, another has passed the sickle and is rising in front
of said conveyor, so that the grain never escapes from their detaining pressure.
When the grain is light, the bats may be advantageously adjusted so that they will
pass closer to the sickle and to the conveyor. This adjustinent is effected by turning
the reel arms J³, in their sockets j1, to cause the portion J", to stand further back,
and lower, in that part of its course wherein it approaches the sickle and conveyor.
A further adjustment to adapt the bat to strike the grain at the best angle and also,
effect its distance from the sickle, is effected by turning the bats on the arms J³, and
in order to allow this adjustment, the bats may be secured to said arms by clips j',
which encircle said arms and may be clamped thereon by suitable clamp screws.
