page_text: pinion on the shaft of the binder driving wheel, forming a differential gear by which
the speed of said wheel can be varied. 3 denotes the platform which carries the
grain as it is cut to the elevator 4, consisting of endless aprons 5 passing over rollers 6,
in the upper and lower ends of the inclined supports 7 (the lower rollers not being
shown). These parts may be of any desired construction, they not forming any
part of the present invention.
8 designates two uprights or standards, secured to the rear of the binder frame,
which is located on the opposite side of the machine to the grain-platform, being
connected at their upper ends by means of a transverse beam or bar 9. At the
opposite or front end of the frame is an upwardly-extending bracket 10, and inter-
mediate of said front and rear ends are two upwardly extending arms 12 and 13.
An upright 13ª is also provided at the rear of the frame. These arms, bracket and
uprights support and carry the binding mechanism.
Immediately in front of elevator 4, and a slight distance below the lower roller 6
thereof, is a rod or bar 14, which extends the entire length of the machine and has
its ends secured in the elevator supports 7. Secured at one end to arm 12 is a
rod 16 similar to rod 14, its opposite end being supported by a cross-bar 43 of the
frame. Connected with these bars 14 and 16 are a series of downwardly-extending
inclined slats or bars 17 which slats in connection with the vertical slats 19 connected
with bars 20 and 20" and the short slats 22 depending from the forward part of
bar 20, form guides or ways which conduct the grain from the elevator to the
packing and binding devices hereafter described.
The bar 20 is supported at its rear end by the transverse bar 9 of the frame and
at its front end by an arm 7 secured to and projecting from the carrier frame 7.
The lower bar 20ª is supported at its rear end by a standard 13" secured to the
lower rail of the frame, and at its front end by the arm 13 of the packer.
Pivoted to bar 23 secured to uprights 8 is a two-armed lever 24, one arm of
which is connected by means of a bar 25 with a bell-crank lever 26, secured to an
oscillating shaft 27, journaled in beam 23 and an upwardly extending arm 28
formed with bracket 10, the other arm of said lever 26 being connected by means of
rod 29 with a pinion hereafter described.
The opposite end of lever 24, is connected by means of rod 30 with a crank 31
secured to an oscillating bar 32 journaled in said beam 23 and in the lower inclined
support 7.
These bars 27 and 32 are provided with inwardly extending slats or fingers 33
which form a cradle to receive the grain from the elevator and hold the same
temporarily until ready to be delivered to the packer when by means of the
oscillating bars, levers and other connections, hereafter described, they are moved
downwardly, spreading apart and allowing the grain to be deposited in the
packer.
The packer which receives the grain from the cradle and compacts it into a
gavel or sheaf, and holds the same during the binding operation, consists of two
metallic half rings or sections 34 and 35 pivoted together, the peripheries thereof.
being smooth or plain, while their interior surfaces are formed with a series of
equi-distant V-shaped longitudinal grooves 36", which receive a portion of the grain
comprising the gavel, so that it may be seized by the twister hereafter described
and twisted into a binding rope.
These sections where they are connected together are cut away upon opposite
sides forming lugs 37 through which passes a shaft 38, which forms the pivot thereof,
the lower section 35 being rigidly secured to the arms 12 and 13 while the
section 34 is securely fixed to the rod 38. This rod extends to the rear of the
apparatus, and is journaled in arm 13ª, where it is provided with a cogged pinion 39,
which meshes with a cogged segment 40 fixed to an oscillating rod 41 journaled in
one of the uprights 8, and the bracket 10 being also provided with an upwardly-
projecting arm 41ª carrying a roller 41° at its upper or free end.
Pivoted to a cross-beam 43 at 43", which cross-beam is connected with the uprights 8,
are two curved arms 44, which carry at their lower ends forwardly extending rods 45,

page_text: which extend nearly to the packer. At their upper ends these arms are pivoted
to a curved arm 46 pivoted at 46" to the cross-bar 43 and having at its lower end
an extension 47 provided with a slot 48 within which works a stud 49 secured to
the segment 40. The rods 45 are provided with inwardly-projecting slats or
fingers 44 which support the gavel or bundle while being bound, and which at the
proper time spread apart and allow the gavel to be discharged when the binding
operation is completed, as will hereinafter appear.
The driving mechanism by which the various parts of the binding mechanism
proper are operated, is supported by the bracket 10 which has formed integral
therewith or firmly secured thereto a hub 50 and cogged disk 51. Through this
hub passes a short shaft 52 one end of which is provided with a bevel gear 52ª
meshing with similar gear 2 on shaft 2d. The other end of this shaft carries a
large wheel 42 which rotates with the shaft and is provided on its outer or front
face with two outwardly-projecting segmental flanges 53 and 54, the flange 53 being
shorter than the one 54, spaces being formed there between to receive the gates 56
and 57. The gate 56 is pivoted to the face of wheel 42 intermediate its ends,
and tapers to a point at one end, the opposite end being made flaring as shown in
Figs. 3, 4, 5, and 6, and the inner face of said gate being made with a double curve.
The enlarged or flaring end is provided upon its outer side with a nose 55 which
abuts against a corresponding recess in the end of flange 53 whereby the movement
of the gate is limited. The gate 57 is pivoted to wheel 42 at 59, and has its inner
and outer faces curved and the point thereof is adapted to strike against one end
of flange 54 which is provided with an inwardly-projecting curved finger or lug 60.
Fixed to a shaft 61 projecting through wheel 42 is a pinion 62 which meshes with
the cogged disk 51. Upon the opposite or rear face of said wheel is a housing 63
in which is journaled one end of a shaft 64 which is provided with a pinion 65
meshing with a pinion 66 fixed to the shaft 61. The opposite end of shaft 64 is
journaled in a cage 67, in which is journaled a shaft 68 at right angles to shaft 64
and is provided at its outer end with a bevel pinion 69 which gears with a corre-
sponding pinion 70 on said shaft 64. This cage is carried by a rigid arm 64*
connected with the housing and is so constructed and located as to work or run
upon the periphery of the packer, being provided with a roller 67ª which runs
thereon. At the inner end of this cage is a finger 71 by which the strands are
seized and turned outwardly and presented to a twisting device mounted upon the
end of shaft 68. This twister consists of a series of curved blades 72 radiating from
said shaft, three being shown in this instance, although the number may vary.
These blades being fast on shaft 68 rotate therewith and catch the strands as
they are successively bent up by the finger 71, twist the same together and lay them
down upon the gavel, forming as it were, a rope which encircles and binds the bundle
or sheaf.
Projecting rearwardly from the movable section of the packer is an extension 73
having a race 74, in which works a tucker by means of which the last strand caught
and turned by the picker finger is tucked underneath of the strands first twisted.
This tucker consists of a metallic bar 75 having a longitudinal groove in its upper
side and having its front end outwardly beveled, forming a jaw 76 and provided
with upwardly-extending lugs 77 in which is centrally pivoted a curved jaw 78.
Connected with the lower end of the pivoted jaw and located in the groove in the
tucker-bar is a sliding bar 79 having an upwardly extending pin 80 which works in
a slot 81 in an arm 82 fixed to an upwardly-projecting shaft 83 pivoted in the
extension 73. The end of this arm which is secured to said shaft is formed or
provided with two notches 84, 85, (see Fig. 14) with which is adapted to engage a
pawl 86 having a hooked end 87 pivoted to the extension 73, a spring, 88 bearing
against the same so as to force said hook into the notches.
89 denotes a curved rod passing through a guide 91 in the movable section of
the packer and having its upper end bent at an angle and inserted in an aperture
in the pawl 86. The opposite end of rod 89 is bent into hook-form and engages

page_text: with a stud 90 on the stationary section of the packer. A spring 92 on said movable
section bears against the rod and holds it in engagement with the stud 90.
The shaft 83 is provided with a coiled spring 93 one end of which is connected
with the extension 73 while the other end passes through an aperture in the shaft
by which it is held. To the upper end of the shaft is secured a plate 94 having
two projecting arms 94 and 94 which are adapted to be successively struck by
the cage 67 in its movement around the packer, whereby the tucking devices
are actuated. The arm 94 is longer than arm 94ª for a purpose hereinafter
explained.
Upon their front faces the two sections of the packer are provided with plates 95
corresponding in shape therewith and having recesses therein, with beveled sides 96.
These plates are secured to the packer by means of headed screw-bolts 97 passing
through slots 97ª therein by means of which they are adjustable so as to vary the
size of the V-shaped grooves in the packer and cause them to take up more or less
grain from the gavel and thus varying the size of the binding rope.
Secured to the movable section of the packer is an inwardly-projecting arm 98
which acts as a lifter when the section is opened, and serves to lift the butt end of
the bound gavel and aid in depositing the same on the ground.
The operation is as follows:
--
Motion is communicated to the wheel 42 from the driving axle of the reaper
through the medium of the sprocket chain, differential gearing and shafts and the
bevel 2 and 52ª. Assuming the parts to be in the position shown in Figs. 5 and 12,
the packer has just been opened, the arms forming the cradle which receives the
grain from the elevator also opened, and the arms which support the grain or gavel
in the packer closed, so that the grain from the elevator will be received by the
packer and lower closed cradle. The construction and arrangement of the cradles
and their connections are such, and their movements are so timed that when a
sufficient quantity of grain has been received by the packer to form a gavel or sheaf
the upper cradle will close. When the gavel has been bound as hereinafter
escribed the packer and the lower cradle will open allowing the bound sheaf to fall
to the ground, whereupon said lower cradle will close and the upper one open to again
allow the grain to be received by the packer and the lower cradle. The lower
cradle assists in supporting the grain in the packer.
These operations are caused by the roller 41° engaging with the inner curved
face of the gate 56, whereby the upwardly-projecting arm carrying said roller is
turned sideways as seen in Fig. 5, oscillating rod 41 and through the medium of
the segment 40 and its pinion, also oscillating rod 38 which will open the movable
section of the packer so as to receive the gavel. As the wheel continues its
movement, the roller will strike the inner face of the extension of the gate, closing
the latter as seen in Fig. 6. The said roller will then strike the curved lug 60 of
the flange 54, whereby it is forced outwardly, causing the arm 41ª to resume its
perpendicular position, and the rod 38 to be moved in an opposite direction by
means of the aforesaid pinion and segment actuating said rod so as to close the
packer and compact the gavel therein, the grain at certain points on the
periphery of the gavel entering the V-shaped grooves on the inner surface of
the packer.
During the revolution of wheel 42, a rotary movement is given to the shaft 64
carrying the cage 67, through the medium of the cogged disk 51, pinion 62, and
pinions 65 and 66 on the rear face of the wheel 42. The parts are so adapted that
immediately after the packer closes and compacts the gavel therein and in the
grooves 36, the finger on the cage will engage with and catch under the grain in
the groove in the movable section nearest the pivoted shaft 38 turning it up so
that it will be caught by the blades of the twister which is rapidly revolved through
the medium of the beveled pinions 69 and 70. As the cage continues its move-
ment, the finger will successively engage with and turn up at right angles the
strands of grain in the grooves, which by means of the twister will be twisted into

page_text: the form of a rope and laid around the periphery of the gavel. By the time the
first strand is twisted and the twist is far enough advanced to take hold of the
second strand, the front part of the cage will strike the arm of plate 94 causing
the bar 79 to be projected forwardly the jaws on the end thereof engaging with
the twisted strands and forcing the same a short distance away from the face
of the packer and holding them between the jaws 76 and 78, the pawl 86
engaging with notches on the arm 82 and preventing backward movement of the
tucker.
The initial movement of the tucking mechanism caused by the cage striking the
arm 94ª moves the bar 79 forward in the groove or channel of the bar 75,
independently of the latter until the parts assume the position shown in Figs. 16
and 16. When this position is reached the rear end of the jaw 78 strikes the
bottom of the race 74 in which the bar 75 slides and is prevented from turning
further until the end of the jaw passes out of the race, which does not occur until
the cage strikes the arm 94° in the next revolution.
From the foregoing it will be understood that the movement imparted by the
cage striking the arm 94ª first moves the bar 79 forward in the bar 75, turns the
jaw far enough to pass over the twisted strand, then moves the two bars 75, 79,
forward together until the nose 76 of bar 79 passes under the twisted strand as
represented in Fig. 16, and leaves the parts in such position that on the next
revolution the last strand will be laid over the jaw 78, as shown in Fig. 164. The
cage then strikes the arm 94° whereby a further movement is imparted to tuck the
last strand under the first. During this second movement the bars 75 79 again
move forward together until the rear end of the jaw 78 passes out of the race 74,
when the bar 75 stops and the bar 79 moves forward independently whereby the
jaw 78 is turned into the position shown in Fig. 16³ carrying with it the last
twisted strand (marked B) and clamping it in the notch 100. When the limit of
independent movement is reached by the bar 79 (which limit is determined by the
pivotal connection between the two bars and the jaw 78) the two bars again move
forward together until the strand B is passed under the first twisted strand
(marked A) when the tucking operation is completed. The parts are now released
and returned to their normal positions as will be hereinafter explained. The
initial return movement draws the bar 79 back to the full limit of its independent
movement in the bar 75 turning the jaw 78 forward, after which the two bars move
back together into their retracted position.
As the wheel 42 continues its revolution the gate will again come to its first
position, but owing to its having been closed by the roller 41 striking its extension
the arm carrying the same will not be actuated as the roller will pass by the gate
without engaging therewith as will appear from Fig. and the packer will remain
closed. As the wheel continues its movement the roller will strike the outer face
of the extension of the gate, opening the same, as seen in Fig. 4 so that on the
revolution the roller will engage with the gate to open the packer and allow the
bound gavel to fall to the ground.
As the cage approaches the point at which it started, the finger will catch
the strands in the last grooves of the packer and the twister will bend them down
between the pivoted jaw 78 of the tucker and the front face of the packer, as seen
at B Fig. 164, the jaw 76 having been forced outwardly from the face of the
packer by the rod 79 as before stated, so that said pivoted jaw will lie in the path
of said last twisted strand, which will thus be deposited in said jaw.
When the cage has passed to the position shown in Fig. 12, the packer in
opening will cause the pawl to be disengaged from the notches on shaft 83 by
means of the rod 89, when the coiled spring 93 will return the two-armed plate and
the tucker to their normal positions..
On the free end of rod 89 is formed a hook which engages the pin 90, the hook
being so shaped (see Fig. 14) that it may ride over the pin in either direction.
The spring 92 is stronger than the spring 88 being strong enough to hold the hook
of rod 89 in engagement with the pin 90, until the pawl 86 is drawn out and

page_text: disengaged from the notch in the hub of arm 82, when the latter will immediately
return to its normal position under the action of spring 93.
From this it will be understood. that the tucking mechanism is released and
returned to its normal position at the beginning of the opening movement of the
packer and before the rod 89 is disengaged from the pin 90. The continued move-
ment of the upper section of the packer then disengages the rod 89 from the
pin 90, whereby the pawl 86 is also released and permitted to resume its normal
position under the action of its spring 88. When the packer is again closed the
hooked end of rod 89 will snap over the pin 90 and the parts will all be in position
ready for the next operation.
From the above it will be seen that the cut grain is fed to the packer with the
butt ends pointing to the front of the binder and with certain of the strands lying
in the grooves in the packer. The finger of the cage running upon one side of the
packer near the periphery will then catch underneath the strands in the grooves,
turning them outwardly and presenting them to the twister, which will twist and
lay the same down upon the periphery of the gavel at right angles to the length
thereof, twisting them into a rope and finally by means of the tucker, tucking the
ends of the last strands caught by the finger under the first twisted strands, thereby
firmly and securely binding the gavel. The gavel is then discharged from the
packer and the device ready for a repetition of the operation.
