I ALFRED JULIUS BOULT of 323 High Holborn in the county of Middlesex,
Engineer do hereby declare the nature of this invention for "IMPROVEMENTS IN
HARVESTER BINDERS A communication from Henry S. Blackburn of Glencoe
Ontario, Canada, Gentleman and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :--
The object of the invention is to devise a simple harvester-binder possessing the
combined advantages of a low-down and elevating binder and also to arrange the
binding mechanism in such a manner that it may be readily adapted and applied to
an ordinary reaping machine; and it consists essentially in attaching to the grain
table of a reaping machine at a point where the grain is usually discharged a
curved grain receptacle above which the binding mechanism is suspended, a circular
moving elevating fork or forks being connected to and operated by the binding
mechanism so as to gather the sheaf from the grain receptacle and elevate it to the
binding mechanism which is arranged and operates substantially in the manner
hereinafter more particularly explained.

In that class of harvester-binders commonly known as the low-down binder the
sheaf is conveyed to the point where the band is placed round it exactly in the
way that the grain falls outo the grain table of the reaper-that is to say-part of
it may be lying in one direction while the other parts are lying in other directions;
consequently the sheaf is in some classes of grain very imperfectly made. In the
elevating binder the grain is straightened by gravitation as the sheaf is raised on
the elevating canvas to the knotting-mechanism.
In this improved harvester-binder the advantage of the elevating binder is
secured while at the same time all of the many advantages of the low-down
binder are obtained, and moreover the plan for connecting the binding mechanism
to the reaping part of the machine is such that it can readily be adapted to and
arranged upon an ordinary reaping machine. With the view of facilitating the
description of the component parts composing this improved harvester-binder I
will proceed to describe in detail the arrangement and operation of each com-
bination of parts effecting the manipulation of the grain from the time it falls
onto the grain table until it is discharged from the machine properly bound into
sheaves.
It may be mentioned here that the ordinary rake is used for sweeping the grain
off the grain-table, A, and as the rakes used operate in the same way as the rakes
on ordinary reaping machines it is not necessary to exhibit them in the drawing or
to specifically describe them in the specification. It will be sufficient to say that
when it is desired to sweep the grain off the grain-table A that the rake is tripped
into action in the ordinary way, and as soon as the sweeping rake has performed
its function it is thrown up in the ordinary way and as it travels up on the
ordinary cam track a it comes into contact with the pivoted lever B and moves
the said lever so as to put the entire binding mechanism into action as hereinafter
more particularly explained in detail. To understand the first motion it will be
necessary to refer to Figures 1 and 11 in which it will be found that the bevelled
gear C is fastened upon the horizontal spindle & which derives motion from the
main driving axle B. This bevelled gear c meshes with the bevelled pinion o
which is attached to the vertical spindle f. The half clutch works freely
vertically upon the spindle ƒ but is prevented revolving thereon by a feather key
in the ordinary way. This half clutch g is arranged to mesh with its corresponding
half clutch which revolves freely on the spindle fand is attached to or forms
part of the disc i.
In Figure 11 the clutch g. . is shown connected consequently the motion of the
gear c is imparted to the disc i but which disc stops immediately that the connection

page_text: is sweeping the grain off the table A the portion of the clutch is held clear of the
portion of the clutch marked h by the spring plate C.
When the rake arm D comes in contact with the lever bit presses it over causing
its bottom end to press down upon the spring plate C which is connected as
indicated to the portion of the clutch marked g and brings it into gear with the
portion of the clutch marked thereby imparting the motion of the machine to the
disc ¿.
When the plate Cis pressed down to the position it is indicated in in
Figure 11 the hook or latch E springs over the plate and holds it down as
indicated.
.
When the disc i has made one revolution a bevelled projection j formed on its
periphery comes in contact with the latch E throwing it clear of the plate C the
tendency of which is to spring up and carry the portion of the clutch marked g
out of gear with its fellow consequently causing the spindle d to stop. On
reference to Figure 1 it will be noticed that a rod F is connected at one end to a
crank-pin formed on the bottom of the disc i and that its other end is connected
to a crank formed on the bottom end of the pivoted spindle of the butter G. When
the disc is caused to revolve the butter Ġ is turned on its pivot so as to sweep
the grain off the table A and as this action is produced at the moment that the
rake has left the grain it is sweeping from the table A the butter G completes tho
motion and pushing against the stubble end of the grain forces the gavel onto the
curved grain receptacle H where it lies in a position to be acted upon by the elevating
forks I which are in the position shown in Figure 1 until this period when they are
thrown into action by the revolving mechanism to understand which it will be
necessary to refer to Figures 1 and 2. A rod K is connected to the rod F and
passes freely through a hole in the crank-m which is pivoted upon the frame J.
A dog n is fixed to the rod k so that it will come in contact with the crank mat
the period when the rod F has thrown the butter G the extreme distance that it is
carried for the purpose of pushing off the grain from the table A.
The pressure of
the dog n against the crank m turns the said crank and as this crank is connected
by the rod o to the lever p which is pivotted upon the frame J a corresponding
rocking motion is imparted to this lever p and its rocking movement is conveyed
by the rod to the pivoted dog q the free end of which presses against the spring
plater which is connected to the hub of the sprocket wheel a which revolves freely
on the main driving axle B until its clutch face is thrown into gear with the
clutch t which is keyed to the axle B by the outward movement of the spring plate r.
So soon as the sprocket wheel 8 is connected to the axle B the motion of the axle is
imparted to the sprocket wheels and as this sprocket wheel is connected by the
chain to the sprocket wheel v the motion of the axle B is conveyed to the cam
disc L to which the sprocket wheel is attached.
On reference to Figure 2 it will be seen that a sliding plate w is held in a groove
formed in the side of the frame J. Two wrist-pins x. y. are attached to and
extend from the sliding plate W at the opposite ends of the said plate. One wrist
pin is designed to fit into the cam formed on the inside surface of the cam
disc L. The other wrist pin y passes through a slot made in the bell crank M
which is pivoted as indicated on a bracket attached to the frame J. The rod N
connects the bell-crank M to the rock-shaft O on which the arin P is fastened.
The upper end of this arm P is connected by the rod Q to the lever R attached to
the segment gear S which meshes with the segment gear T attached to the shaft U
to which the forks V are attached. The cam z is so shaped and arranged in
connection with the wrist pin x that while the cam disc L is revolving the cam
carries the wrist pin x from the point it is shown in in Figure 2 to the point it is
indicated in in Figure 7 and as the sliding plate w must move with the pin x the
bell crank M is moved sufficiently to carry the forks I from the position they are
shown in in full lines in Figure 2 to the position they are indicated in in dotted
lines in the same figure in which position they hold the sheaf ready for the binding
mechanism which-is at this period put into action. It will be noticed on reference
to Figure 7 that owing to the shape of the cam the wrist pin x remains stationary

page_text: during the period that the cam travels from the point it is shown in in Figure 7 to
the point it is indicated in in Figure 8 which period is the time that the binding
mechanism is operating, to understand which it will be necessary to refer to
Figures 7 and 8. A sliding plate or head V is fitted into and works within a
vertical groove or guide X formed on the main frame of the machine. A wrist-
pin 2 is attached to the sliding plate W and fits into the cam z which imparts to
the said plate a vertical reciprocating motion. A rack-bar 3 is attached to the
sliding plate V and meshes with the segment gear 4 which is attached to the
horizontal shaft 5 to which the needle Y is fastened and by which the compressers
are put into action as we shall now proceed to describe in detail, and will refer to
Figures 7. 8. and 9 for the purpose of the description. A. notched disc 6 is keyed
to the shaft ŏ while the arm 7 is fitted loosely onto the said shaft but is connected
to the bearing box 8 by the spiral spring 9, one end of the said spiral spring 9
being connected to the arm 7 while its other end is connected to the bearing-box 8
and the said spring is set so as to impart an upward movement to the arm 7.
A dog 10 is pivoted on the arm 7 and is arranged to engage with a notch made in
the disc G by means of the spring. 11 is the front compresser pivotted on the
frame of the machine and connected by the toggle jointed bars 12 to the pivoted
arm 13 the bottom end of which fits below the spring plate 14.
The centre joint
of the bars 12 are connected to the arm 7 by the rod 15 so that the downward
movement of the arm 7 shall by straightening the toggle-jointed bars 12 cause the
front compresser 11 to move from the position it is indicated in in Figure 7 to the
position it is shown in in Figure 8 for the purpose of compressing the front side of
the bundle about to be bound. The back compresser 10 is attached to a spindle on
which the segment gear 17 is fastened. This segment gear 17 meshes with the
rack rod 18 the opposite end of which meshes with the segment gear 19 which is
attached to the spindle on which the arm 20 is fastened. On the end of this arm 20
a rod 21 is connected which passes through a hole in the forked rod 22 the lower
end of which is connected to the arm 7 A spiral spring 23 fits between a collar
on the bottom end of the rod 21 and the face of the hole through the forked rod 22
so as to form a longitudinal elastic connection between the arm 7 and the arm 20
in order that the compresser 16 may be permitted to expand slightly in the event
of a larger gavel than usual being connected.
is a stop formed on the frame against which the arm 7 strikes thus regulating
the sweep of the compresser arm 16 as indicated in Figure 7. The spring plate 14
which is arranged as before described is intended for the purpose of permitting the
same elastic action for the front compresser 11. When the horizontal shaft 5 is
caused to rock in its bearing by the action of the rack-bar 3 and segment
gear 4 operated by the cam z as hereinbefore described the motion of the said shaft
moves the needle up into the knotting mechanism and at the same time the notched
disc 6 actuates through the dog 10 the arm 7 which conveys as before described the
necessary motion to the compressers 11 and 16. Simultaneously with the action
of the mechanism just described the harpoon fork 24 is brought into action by the
upward motion of the sliding plate V which is connected by the rod 25 to the
arm 26 connected to the harpoon fork 24 by the segment gears 27 and 28 as
indicated. The action of this harpoon fork may here be described.
While the wrist pin 2 is being pushed up by the action of the cam disc L from
the position it is shown in in Figure 7 to the position it is indicated in in Figure 8
the harpoon fork 24 is moved from the position it is indicated in in Figure 7 to
that in which it is shown in Figure 8, the former position being clear of the bundle,
while in the latter position it is forced into the end of the bundle held during the
process of binding. The bracket 29 is grooved as indicated in Figure 5 to receive
a wrist pin 30 attached to a slide 31 fitted upon the harpoon fork 24. This
slide 31 is connected by the jointed rod 32 to the harpoon points 33, as indicated
in Figure 6 so that the upward movement of the slide 31 causes the harpoon
point 33 to recede into the fork while the downward movement of the slide 31
forces the harpoon point 33 out into the position indicated in Figure 6: ẞ is a gate

page_text: pivoted on the end of the bracket 29 and kept in position by the spring a the
gate being on an incline and when the pin 30 passes the incline it drops down
into the groove again being prevented by the form of the gate, as shown in
Figure 5, from receding into the lower groovo.
34 is a finger attached to the slide 31.
35 is a bell crank pivoted in the frame of the machine and having one of its
-arms projecting beyond the bracket 29. The chain 36 seen in Figure 10 conveys
notion to the shaft 37. On this shaft is fastened the segment gear 38 from which
the knotting mechanism derives its motion as hereinafter described. A cam
wiper 39 is also fastened to the shaft 37 and is located in front of one of the
arms of the bell crank 35. At the same that the harpoon fork 24 is forced into
the end of the bundle herein before referred to the cam wiper 39 has been brought
by the motion of the shaft 37 to a point which will cause the bell crank 35 to tilt
and as at that time the finger 34 is below the bell crank and the wrist pin 30 is at
the lower end of the bracket 29 the said tilting of the bell crank 35 forces the
wrist pin 30 from the upper to the lower groove made in the bracket 29 carrying
it down to the position it is indicated in Figure 5. By thus pressing down the
wrist pin 30 the harpoon points 33 are forced out from the fork thereby forming a
connection between the fork and the bundle. By the time that this action is
performed the tying of the bundle has been effected and the bundle is ready to be
discharged from the machine. On reference to Figure 9 it will be seen that on the
face of the segment gear 38 is placed a pin 40 arranged to come in contact with
the hub formed on the rod 41 the loop end of the said rod fitting over the
shaft 37 while its lower end is connected to an arm 42 having a projection to fit
below the dog 10. When the pin 40 has raised the rod 41 sufficiently to force the
dog 10 out of gear with the notched disc 6 the arm 7 is released and is carried
upwardly by the action of the spring 9, thereby causing the compressors to spring
away from the bundle. The downward movement of the wrist pin 2 carries the
needle away from the bundle and at the same time the harpoon fork is carried back
to the position it is indicated in Figure 7, carrying with it the bundle, the stubble
end of which hangs downwardly. When the wrist pin 30 reaches the top end of
the bracket 29, it is by the form of the groove in the said bracket drawn upwardly
on the fork 24, which action as before described causes the harpoon points 33, to
recede into the fork thereby releasing the bundle and permitting it to drop to the
ground where it falls on the stubble end without injuring the sheaf. By the time
that all these motions described have been accomplished, the cam wheel L, has
made a complete revolution and the connection between the binding mechanism
and main driving axle is broken in the following manner.
On reference to Figure 2 it will be seen that the rod k has a shoulder, 43 placed
on its top side, and that a plunger 44 rests upon the said shoulder. This plunger
is actuated by a spring 45 which compresses the said plunger down and when the
rod is moved as described in the cominencement of this specification, the
shoulder 43 passes the plunger and the spring forces the plunger down behind
the shoulder 43, which action secures the rod and causes it to hold the clutch, t,
in gear so as to connect the binding mechanism with the axle B, as hereinbefore
described.
46 is a rock shaft one arm of which is connected to the plunger 44, while the
other arm projects over the periphery of the cam dise L upon which is formed a
wedge shaped projection 47. By the time that the cam disc L has made a complete
revolution, as before explained, the wedge shaped projection 47 passes below the
arm of the rock shaft 46, causing the said rock shaft to move so as to raise the
plunger 44 clear of the shoulder 43 thereby releasing the rod, Mk and permitting
the spring r to carry the clutch out of gear where it remains, until again put into
action, as described at the commencement of this specification.
Having now described the mechanism by which the bundle is gathered-and held
during the operation of tying, I shall proceed to explain the construction..and

page_text: operation of the knotting mechanism and refer to Figures 12. 13 14. 15. 16. 17. 18,
and 19 which exhibit the mechanism constituting the knotter.
Segment gear 38 which derives motion from the main axle B, of the machine, as
before described, has a plane rim 48, for about three fourths of its circumference.
This rim fits into a circular recess 49, formed behind the teeth of the spur
pinion 50. This pinion 50 is keyed or otherwise fastened to the shaft or spindle 51
upon which the cams for operating the knotting mechanism are attached during
the period that the rim 48 fits into the recess 49, the knotting mechanism remains
stationary, but as soon as the teeth on the segment wheel 38 come in contact with
the teeth of the pinion 50, the said pinion is caused to revolve, and the mechanism
is thus put into action; there being just sufficient teeth in the segment wheel, 38,
to cause the pinion 50 to make one revolution which revolution is sufficient to
perform the entire knotting operation By the time that the teeth have passed the
pinion 50, the recess 49 has once more come opposite to the wheel 48, and the
rim 48 once more enters the recess, thereby holding the pinion 50, perfectly
stationary and the mechanism in its initial position, as indicated in Figure 12.
When the needle is thrown up into the knotting mechanism as shown by dotted
lines in Figure 13 the cord 52, encircles the bundle which would be held within
the loop we have marked "53" in Figures 13 and 14.
The tucker 54, is pivotted at 55, and is connected by the rod 85 to a pin 57,
attached to a slide fitting in the guide block 50.
The other end of this slide has a
pin which fits into a cam groove formed in the cam 58.
Neither the pin nor the slide is seen in the drawing, but it is not necessary that
they should be, as any one will understand how to connect the cam 58 to the end
of the rod forming part of the tucker 54 in order that the revolving of the cam 58
shall impart a reciprocating movement to the tucker. When the teeth of the
wheel 38 first mesh with the pinion 50, the cam 58 is first brought into action
causing the tucker 54 to move from the position in which it is indicated in
Figure 12 to the position in which it is shown in Figure 13 which action tucks the
cord 52 into the recess of the stripper 59. Simultaneously with the movement
of the tucker 54, the cord holder, into one notch of which the cord has just been
deposited by the needle, is caused to revolve by the action of the ratchet pawl GO,
which connected as indicated in Figure 15 to the bell crank 61 the opposite end
of which is connected to the rod 85 of the tucker 54 and by so revolving compresses
the cord against the spring 86 on the pivoted arm 73, thus holding the cord
securely in position during the process of tying the knot. 87 is a spring fork
pivoted on the spindle of the cord holder and arranged to keep the holder clear
from the fibres of the cord. When the cam 58 has revolved so as to bring the
tucker 54 from the position it is shown in Figure 12 to the position in which it is
shown in Figure 13 the shape of the cam then acting on the pin of the slide before
referred to being such that the mechanism connected therewith remains stationary
although the cam continues to revolve. When the tucker ceases to move, cam 62,
begins to move the rod 63, in the direction indicated by arrow, and as the opposite
end of this rod 63 is connected to the quadrant rack 64, the said quadrant is
moved from the position in which it is shown in Figure 12, to that in which it is
indicated in Figure 13. and as this rack 64, meshes with the teeth 65 connected to
the bill hook 66, the said bill hook is made to make one revolution. By the time
that the bill hook 66 has reached the position in which it is indicated in Figure 13
the jaws are opened and closed so as to grip the cord 52, with the view of under-
standing this action we would refer to Figures 16 and 17, in which the construction
of the bill-hook is exhibited. The upper jaw of the bill hook forms part of the
spindle 67, which passes through suitable bearings formed in the bracket, 68. The
lower jaw of the bill hook 66 is pivotted at 69 to the upper jaw, and its back is
connected to the rod 70, which fits into a groove made in the spindle 67. On the
upper end of this rod 70, I place a friction roller 71 which fits on a cam track 72
formed in the bracket 68.

page_text: When the spindle 67, of the bill hook is caused to revolve by the action of the
quadrant rack 64, the friction roller 71, mounts a high point on the said track just
before the bill hook 66 has reached the cord, 52, thus causing the lower jaw of
the bill hook to change from the position in which it is indicated in Figure 16
to the position in which it is shown in Figure 17. By the time that the cord 52,
has entered the jaws of the bill hook 66, the high portion of the track 72, has
been passed and the jaws of the bill hook closed so as to grip the cord which it
holds until withdrawn from it by the movement of the stripper 59. The arm 73
which carries the cord-holder 74 is pivoted at 75, and is connected to the cam 76
by the pivoted rod 77. The shape of the cam 76 is such that at the time that the
bill hook 66 has reached the position which it is indicated in Figure the pivoted
arm 73 is permitted to fall from the position in which it is shown in Figure 13 to
the position in which it is indicated in Figure 14 which movement loosens the cord
and gives sufficient slack to allow the cord 52 to pass through the loop formed
around the bill hook when the stripper 59, is moved from the position in which it
is shown in Figure 13 to the position in which it is indicated in Figure 14 which
motion is effected by the action of the cam 78, which is connected to the stripper
by the rod 79. The plate 80 on which the knife 81 is formed is pivoted at 82,
and has a slot 83, made in it to receive the end of the pin 8+, which the rod 79 to
the plate 80. When the stripper is moved by the action of the cam 79, the knife
plate 80, is moved so as to cause the knife 81 to pass between the bill hook 66, and
cord 74, thereby cutting the cord at that point just as the stripper 59, is about to
pull the cord off the bill hook. By the time that this is accomplished the recess 49
has once more come opposite the plain rim 48, and the shaft 51 remains stationary
holding the knotting mechanism in its initial position until the next knot is
required.
