Harvesting Machines.
I WILLIAM MCINTYRE CRANSTON of 36 Worship Street, Finsbury in the county of
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, to be as follows:-
This invention relates to certain improvements in connection with the binding
mechanism of harvesters, the binding being effected by straw, twisted into string form,
or twine.
According to this invention the grain arriving to the binding mechanism is gathered
by an arm having a reciprocating circular movement against a fork mechanism which
has also a movement when sufficient quantity has been gathered to form a bundle,
said forks then by the pressure exerted upon them causes a lever to cant and at the
same time a double spring plate to move, one end pressing upon a curved or cam
collar to ride sideways to throw a clutch out of gear and compressing a spring
encircling the shaft on which the clutch pinion is mounted, the other leg of the spring
plate at this moment escapes from the-nose of a wiper or cam of a shaft on which
the binding arm is carried and releases the leg of the double plate the action of which
by its spring takes the coupling leg out from between the coupling and a fixed collar,
this action puts the pinion into gear with a toothed wheel (on the same shaft as the
wiper) which operates the binding arm, the gathering and packing arm continuing
its motion during the time the binder is at work.
The gatherer is formed of two pointed jaws one of which hangs from two pivots
both movable for the reciprocating circular movement, the other jaw is pivotted in the
first named jaw and has an arm projecting at right angles or nearly so, which rides
loosely in a slot of a plate forming part of a bracket by which the first named jaw is
carried and so fitted that when the binding mechanism comes to them for passing a
rope of straw, or string round the bundle the loose jaw opens outwards and allows the
binder to enter in between the jaws and in the path of the main portion of the rope of

page_text: straw or twine for gripping the same. One of the objects of the supplementary jaw
is to prevent loose straws getting into the knotting mechanism of the binder arm
another object is to assist in the gathering.
The tying mechanism is fitted between two plates and during part of the travel is
actuated by a series of lugs on a plate (which has a distinct movement) acting upon
pins or projections on the back of a disc, the inner face of which is provided with
teeth in the segment of a circle in gear with a pinion on a spindle carrying the
knotter to rotate it. Said knotter spindle has two irregular spiral threads thereon so
that when the spindle is turned, one of said spirals move a sliding plate forming part
of a grasper and the other moves a plate forming part of a lifter to regulate the
crossings of the twine during the movement of the knotter for the proper formation
of what is known as a Weavers or whip knot, or by modifying the shape of the
appliances any other knot can be formed.
The grasper is in two pieces but capable of moving together during one part of
the tying operation but one having an extra motion from a cam on the main crank for
opening and shutting the grasper. This additional piece has a box containing a spring
which when the pressure is removed allows the two pieces to come together again to
hold the rope firmly between them. The outer end of one piece of the grasper is
provided with a pivotted lug which, when the knot is completed, forces the rope
against a fixed knife which cuts it.
The knotter at the back of the entry point of its inner face has a hook for gripping
the straw rope or twine and during part of its rotation the straw rope or twine is laid
in a segmental annular groove formed in the body of it, a lipped plate retaining it in
position until the knot is formed when the plate is pushed sideways releasing the knot
the lip of the plate being kept in the groove by a spring.

Harvesting Machines.
I WILLIAM MCINTYRE CRANSTON of 36 Worship Street, Finsbury, in the county
of 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 improvements in connection with the binding
mechanism of Harvesters, the binding being effected by straw twisted into string
form or twine.
According to this invention the grain arriving at the binding mechanism, is
gathered by an arm having a reciprocating circular movement against a fork
inechanism which has also a movement when sufficient quantity has been gathered
to form a bundle; said forks then by the pressure exerted upon them cause a lever
to cant and at the same time a double spring plate to move, one end pressing upon
a curved or cam collar to ride sideways to throw a clutch out of gear and compressing
a spring encircling the shaft on which the clutch pinion is mounted, the other leg of
the spring plate at this moment escaping from the nose of a wiper or cam of a shaft
on which the binder arm is carried and releases the leg of the double plate, the action
of which by its spring takes the coupling leg out from between the coupling and a
fixed collar; this action puts the pinion in gear with a toothed wheel (on the same
shaft as the wiper) which operates the binding arm, the gathering and packing arm
continuing its motion during the time the binder is at work.
The gatherer is formed of two pointed jaws one of which hangs from two pivots
both movable for the reciprocating circular movement; the other jaw is pivotted in
the first named jaw and has an arm, projecting at right angles or nearly so, which
rides loosely in a slot on a plate forming part of a bracket by which the first named
jaw is carried, and so fitted that when the binding mechanism comes to them for
passing the rope of straw or string around the bundle the loose jaw opens outwards
to allow the binder to enter in between the jaws and in the path of the main portion
of the rope of straw or twine for gripping the same.
One of the objects of the supplementary jaw is to prevent loose straws getting
into the knotting mechanism of the binder arin. Another object is to assist in the
gathering.
The tying mechanism is fitted between two plates and during part of the travel is
actuated by a series of lugs on a plate (which has a distinct movement) acting upon
pins or projections on the back of a disc the inner face of which is provided with
teeth in the segment of a circle in gear with a pinion on a spindle carrying the
knotter to rotate it. Said spindle has two irregular spiral threads thereon so
that when the spindle is turned one of said spirals moves a sliding plate forming part

page_text: of a grasper and the other moves a plate forming part of a lifter to regulate the
crossings of the twine during the movement of the knotter for the proper formation
of what is known as a "Weavers or Whip knot" or by modifying the shape of
"
"
the appliances any other knot can be forined.
The grasper is in two pieces but capable of moving together during one part of
the tying operation, but one having an extra motion from a cam on the main crank
for opening and shutting the grasper. This additional piece has a box containing
a spring which when the pressure is removed allows the two pieces to come together
again to hold the rope firmly between them.
The outer end of one piece of the grasper is provided with a pivotted lug
which when the knot is completed forces the rope against a fixed knife which
cuts it.
The knotter at the back of the entry point of its inner face has a hook for gripping
the straw rope or twine during part of its rotation; the straw rope or twine is laid in
a segmental annular groove formed in the body of the knotter a lipped plate retaining
it in position until the knot is formed when the plate is pushed sideways releasing the
knot, the lip of the plate being kept in the groove by a spring.
In order that others may fully understand this invention I will now proceed to
more particularly describe the same with reference to the accompanying drawings.

Figure 25 shows the knot in the band before it has been drawn tight.
The binder is attached to the Harvester in any suitable well known way so that the
grain or other crop will be delivered upon the binding platform G'.
In the drawings I have shown it attached to the end cross sill J' of a Harvester
by the castings a to which the transverse arms J, J, are bolted.
Motion is communicated from any suitable moving part of the Harvester by shaft I'
to the packer shaft D which revolves continuously through pinion I and bevil gear. I
secured to shaft D.

page_text: The shaft D revolves in bearings in the arms J, J. Dis the binder arm snart
and is mounted in suitable bearings in the lower limb of the binder frame A. E³ is the
tripping and compressing shaft mounted in suitable journals in the upper limb of the
binder frame A and by the forked lever D controls the action of the binder arm
shaft. D, and the can gear wheel D¹ by the rod D' and cam groove on the inner
face of the wheel D' rocks the shaft and the compressing and trip fingers E
secured to shaft E³ causing said fingers E at the proper moment to compress the
gavel in opposition to the movement of the binder arin and then to rise to permit the
discharge of the gavel.
G' is the binding platform secured to the binder frame A and extending grainwardly
and occupying a suitable position with reference to the harvester to receive the grain
therefrom. It is formed with the transverse slot or opening G' extending from the
point G³ to the outer edge of the binder platform, where it is provided with the
curved blocks G on either side of the opening G to give proper form to and to
sustain the gavel.
The slot G is sufficiently wide to allow the packer arm C and binder arm B to pass
up above the line of the platform.
The shaft D is provided at its inner end with the crank arm C³ (see Figures 13
and 14) in the end of which is pivotted the packer arm C at its lower end. The
packer arm C near the middle of its length is also pivotted by the pin C³ to the
swinging frame C₁ pivotted to the binder frame A.
The swinging frame C¹ is formed, with a lug a through a cam slot in which a
projects an outwardly extending arm a¹³ secured to or formed integral with the jaw a
pivotted to the jaw a by the longitudinal pin a".
The upper end of the packer arm C is curvilinear in form so that it will move the
grain forward but in its retrograde movement will not catch the grain but will be
easily withdrawn therefrom.
When the packer arm is caused to rise above the table the pivotted jaw a² is by
the arm a and cam slot a held up against the jaw a³ so that a single point is
presented to pierce the grain. As the packer arm continues its movement the arm a¹³
rides up in the cam slot a' and the jaw a' is opened thereby affording a clear passage
for the end of the binder arm B between its flanges a' and a similar downwardly
extending flange of jaw a³ and also straddling the band which passes down through
the funnel e and guiding it to the knotter which revolves in the upper end of the
binder armi B. This sidewise movement of the pivotted jaw a² also serves to
straighten the grain. Of course it is necessary that the binder arm and the
packer arm be timed properly so that the binder arm will rise during the
period when the packer jaws are open so that a clear passage be afforded the
binder arm.
The hub E' of the compressing and trip fingers E, fits loosely over the rear end of
the shaft E³ to the end of which shaft is secured the forwardly or outwardly projecting
arm E. A bolt passes through the hole E" in the compresser and trip arm E and
through the arm E1 and is secured by a nut on the under side of the arm E.
A stiff spiral spring E" is interposed between the arms E¹º and E and
surrounds the bolt. A spiral spring E' surrounds the shaft E³ one end of the
spring being secured to the shaft E3 and the other end to the upper limb of the.
frame A.
To the outer end of the shaft E3 is firmly secured the double crank arm D. On
the pin in the inwardly extending branch 13 is suspended the forked lever D¹³.
To the oppositely extending crank is pivotted the arm D'. To the forward end of
the shaft Dis firmly secured the cam D³ revolving continuously with the shaft. It
is of the form shown in Figure 20. The upper half of its inner face, as shown,
is cut away and has the ledge w whose vertical face forms a continuation of the
part d'.
Loosely mounted on the shaft D is the cog wheel D³ and a spiral spring D
surrounds the shaft D and is interposed between the cog wheel D and the arm J
or some fixed portion of the machine (see Figure. 1). The cog wheel D' is formed

page_text: with the recess d' into which fits the projection on the cain D³ and thereby the cog
wheel D is caused to revolve with D³.
During the formation of the gavel the trip and compressing arm E occupies the
position shown in Figure 1 the springs E and E both co-acting to keep it in
this position and forms the outer support against which the grain is packed. At
this time the toe D of the split rod D is interposed between D' and D' holding
them from engagement against the action of the spring D. The heel D³ of rod D₁
now rests on the cam nose con gear wheel D₁ and holds the toe D* between D'
and D at same time pushing Do forward there being sufficient elasticity in the
rod Dis for this purpose.
When however the tripping arm E has been raised a sufficient distance against the
resistance offered by the spiral spring E and through the tension of the spiral
spring E which is made sufficiently strong for that purpose, rocks the shaft E
thereby depressing the crank arm and throwing the toe D out from interposition
between D2 and D³, the heel D³ by the rocking of shaft E and depression of crank
arm D being thrown off the cam nose c, the spring D will force the loose cog
wheel D into engagement with D³ and the cog wheel D' on the binder arm shaft
carrying the binding devices will be revolved.
The cam face c serves as a guide acting upon the heel I³ to guide the toe DⓇ in
between D and D³ as the binder arm is completing its revolution and after the bundle
has been bound and the inner face of the cain D3 which is inclined with respect to
the opposite face of the cog wheel D² serves in conjunction with the toe D to
wedge D away from D³ thereby causing it to cease to revolve and bringing the
binder to rest.
When the binder arm is encircling the bundle and during the formation of the
knot, the arm E is forced downwardly to act as a compresser by the rod D' and cam
groove on the inner face of D². The arm D' is pivotted to the link D³ pivotted to
the frame at 2. The lower end of D' is provided with a fricton roller which
runs in the cam groove do on the inner face of D¹ the groove being so formed that it
will permit the armn D' to be elevated by the accumulation of the grain and the
shaft Es to be rocked to trip the machine, the portion d¹ of the cam permitting this
movement. As the friction roller rides between 8 and the tripping fingers or
fork is elevated to allow the discharge of the sheaf, and is again returned to its
original position for the succeeding gavel. The part of the cam causes the fingerз
or fork to move downwardly in opposition to the needle arm thereby compressing the
bundle.
The spring Do which fits over the rod D1 and is secured at its inner end to the
crank D assists in throwing the toe of the rod D¹ from engagement between D2 and D³.
F F are two curved arms secured to the upper limb of the binder frame between
which arms the binder and the packer arm or gatherer rises and beside guiding the
crop up against the trip ensures the binder arm discharging the gavel as will be
more fully hereafter described.
To the inner end of the shaft D is firmly secured the lugged plate or crank (the
hole c¹ passing over the end of the shaft. C has also the hole C6 in which the binder
arm B is pivotted at e (see Figure 4) by a suitable stud. The binder arm B is also
pivotted at e to the link e pivotted at e to the arm J or to some fixed portion of the
machine. It is apparent that when the lugged crank arm is revolved it will carry
with it the binder arm B the end of which where it is pivotted to the crank arm
being kept uppermost by the link e's until the binder arin has risen above the table,
bound the bundle, and ejected it from the machine.
The binder arm carries the knotting devices which consists of the knotting hook, the
grasper
and band cutter and the detaching hook together with the band lifter or placer.
Motion is communicated to the knotting devices through the lugs on the crank arm C
as will be more fully hereinafter described.
The disk (see Figure 22) is formed with the segmental rack e¹ on its inner face,
and the shoulder p fits loosely within the hole p' in the binder arm and a threaded
stud screwed into the shoulder p forms a bearing on which the disc reciprocates. The

page_text: exterior face of the disc is nush with the surface of the binder arm and is provided with
the pins or lugs kk, on each side of the centre of a chord whose length is somewhat
less than the diameter of the disc (see dotted lines Figure 22). The disc revolves
upon the stud p and bears also upon the upper or outer surface of the flange k³. A
spring stop yl secured to the disc serves to dog it and prevent its rotation except when
the pins , k, are brought in contact with the lugs on the crank arm (the spring
catching in one of the rack teeth on the disc k or on a suitable lug formed thereon for
that purpose.
A hole communicates with the interior of the binder arm and in this opening is the
pinion & secured to the knotter spindle a³ (see Figure 5) the pinion being in mesh
with the rack on the face of the disc k and formed with a sufficient number of teeth to
be given about one and a half revolutions as the disc reciprocates.
Bearings e and e' are formed on the binder arm for the spindle a and corresponding
bearings in the binder arm cover B' which fits over the arm B and shields the
working parts contained therein.
The knotter hook is of the form shown in Figure 6 being provided with the
peripheral groove & in which runs the nose 6 of the band stripper b'. The knotter
spindle is formed with the two reverse cams or spirals a, a, fitting into the spiral
grooves in the lugs a' and a respectively. The lug a' is formed integral with
the band lifter c¹ (see Figure 11) and the lug e is integral with the grasper
operating hook ³ (see Figures 8 and 9).
The revolution of the knotter spindle depresses the band lifter and elevates the
grasper or vice versa in order to place one or the other, as the case may be of:
the binding material so that the knotter hook will pass over or under it at the
proper time for the formation of the knot. The grasper frame 63 carrying with
it the grasper and plate is thus moved up and down together with the nose.
piece c' by the spiral cam on the knotter spindle, but the frame 63 is permitted an
independent longitudinal movement irrespective of the nose piece e².
Suitable bearings are formed on the binder arm B, and and on the
cover B, k and 10 to confine the grasper in its longitudinal movement.
The band lifter c¹ slides freely upon the grasper frame 3 (see Figure 5) upon.
which a suitable bearing is formed therefore, the projection a fitting over the side of
the grasper frame and the cam groove in a confining the band lifter in conjunction
with the spiral on the knotter spindle by which it is moved in the proper.
place. The upper end of the frame 63 is notched out to form a guide for the band (see
Figures 8, 9 and 10) which is held between the pivotted jaw 6 and the head of the
grasper. The pivotted jaw is bifurcated and the shoulder e¹ is formed on the
grasper to pass freely between the forks. The fork extends beyond the fork e
and passes into a recess formed therefore in the grasper. The plate 6 extends into
this cavity or recess and the fork bears against it and severs the band against the
sharpened edge of the plate 6, the band being held as to its end by the forks and.
projection e
Between the notch 1 and the flange on the plate &* is confined the nose piece e of
the plate c which fits over, (loosely) the grasper frame b. The plate & is formed.
with a recess in which is placed a spiral spring c said spring abutting against a
projection cast on 63 (see Figures 8, 9 and 10). The plate is controlled in its
longitudinal movement by the spiral on the knotter spindle and carries with it the
grasper frame as before stated. When however in the revolution of the binder.
arm B the shoulder es of frame comes in contact with the lug c on the arm C³ the
grasper frame is forced upward and c² being held by the spiral cam on the knotter
spindle the pivotted jaw b is forced open through notch 613 and nose piece e thereby
compressing the spring c which keeps the grasper closed when it is not in contact
with the lugs con arm C³. At this time the band is received between the open jaws 7,³
and and then, on the further revolution of the binder arm coming in
contact with lug c on its underside carries the frame downward thereby closing
the jaw band severing the band at the same time grasping the new end, having!
released the old end. 6' is the stripper its shank e³ having a bearing in the-lug e* on:
3

page_text: binder arm B is surrounded by spiral spring e² one end of which is secured to the
arm B and the other to shank e³ and the action of the spring is to keep the nose b' of
the stripper in the peripheral groove in the knotter hook. The knotter cover or cap is
formed with the concaved projection B8 (see Figure 24) between which and the end of
the knotter hook the free end of the band as it is about to be drawn through the
loop is confined.
The band as before stated passes down through the funnel e and then over the
groove d' in the piece d which has the ears do by which it is pivotted between the
arms F just forward of the binder frame a spring (not shown in the drawings) being
interposed between its upper surface and the binder frame. The office of the spring
is to force the pivotted piece d downward so that the band will be guided into the
nose of the binder arm in which revolves the knotter spindle and yet permit the
piece d to yield upwardly. It will be noticed from inspection of Figure 14 that the
fixed jaw as of the packer arm is inclined on its upper edge. The jaw being open when
it is passing the piece d straddles it, and the binder arm rising between the jaws a
and a the band is guided into the proper place in the end of the binder arm by the
inclined edge of a³.
The operation of the machine is as follows:
The band passing either from a suitable containing receptacle or from a twister down
through the funnel e, over the groove in pivotted piece d is held in the grasper carried
by the binder arm B beneath the binding platform. The grain cut by the harvester is
delivered by suitable carrying mechanism upon the platform G. The packer or
gatherer (on the continuously revolving shaft D rising above the table through the
slot G moves forward therein gradually opening and forces the grain against
the band and the retaining fork E until sufficient has been accumulated against said
fork to overcome the spring E' and rocking the shaft E³ disengage the toe De from
between D and D' when the spiral spring D is permitted to act and forces the cog
wheel D' in clutch with the constantly revolving cam D³ thereby causing the gear
wheel D¹ secured to shaft D¹² carrying crank arm C to which the binder arm is
pivotted to revolve. This brings the binder arm above the binding platform in rear of
the bundle drawing the band held by the grasper with it.
The motion of the packer arm C and binder arm B are so timed that the binder arm
advances between the jaws a² and a³ which open for that purpose. As the binder
arm continues its advance, the friction roller on the end of D' riding upon the
portion d of cam d on wheel D¹ forces the forks E downward in opposition to
the needle or binder arm the spring E' allowing the forks E to yield in case an extra-
ordinarily large bundle has accumulated. As the nose of the binder arm B passes
the
pivotted piece d the band passing through funnel e and over d will be guided between
the grasper and the cover B' and will lie upon the band lifter c¹ the various knotting
devices being at this time in the position shown in Figure 5, the grasper raised to its
highest point and the band lifter depressed to its lowest the band being crossed.
As the binder arm continues to advance the lug c striking the pin k' revolves the
disc k and the segmental gear e¹ causes the knotter pinion carrying the knotter spindle
and hook to revolve about one and one half times. The knotter hook passing over
the main band under the grasper end of the band then under the main band and over
the grasper end and again under the main band and over the grasper end, the band
lifter by one revolution of the knotter spindle having been elevated and the grasper
having been depressed sufficiently for this purpose by the spiral cams on-the knotter
spindle.
During this portion of the operation of the knotter a loop has been formed in the
main band around the knotter hook and the grasper end of the band lies across the
two strands forming the loop. The lug c then coming in contact with the pin k
revolves the disc k and consequently the knotter hook as the binder arm advances one
and one half times in the reverse direction. The grasper end of the band, as the hook
commences this reverse movement, is seized in the notch in the hook band carried
under the main band now formed into a loop and over itself and through the loop
forming what is termed a weavers knot. The knot is represented in Figure 25.

page_text: A little after the knotter commences its retrograde movement the lug c strikes the
shoulder or projection of the grasper frame and pushing it upwardly releases
the end of the band permitting it to be drawn through the loop, the end of the band
being held between the hook and the concaved projection on B'. The under surface
of lug c then forces the frame & downward and the main band being between. the
pivotted jaws and the frame b³, the grasper being by this downward movement of
frame closed, is severed and the new end held in the grasper. The nose 63 running
in the peripheral groove in the hook b strips the knot therefrom. The friction_roller
on the rod D' working in the cam groove between do and d" elevates the fork E and
the binder arm continuing to advance pushes the bundle from the machine and the
cam groove between da and d¹ forces the fork downward ready for the succeeding
sheaf.
During the downward movement of the fork E the end of the crank arm D" is
forced upwardly bringing the heol D' in contact with the cam c and guiding Do
between D and D' forces them apart thereby bringing the binder to rest again
ready for a succeeding bundle.
The arms F at their rear ends diverging upwardly from the binder platform serve
to ensure fluffy grain being carried forward by the gatherer and at their forward ends
hold the bundle down so that the binder arm will discharge it.
