"IMPROVEMENTS IN AND APPERTAINING TO AUTOMATIC OR SELF BINDING ATTACH-
MENTS TO HARVESTING MACHINES." A communication from abroad by Herbert
D. Blakemore, of Cincinnati, Ohio.
The object of this Invention is to simplify and improve the construction and
operation of automatic or self-binding attachments to harvesters, and it is adapted
to the use of either wire or cord as band material, according as either a twister or
knotter is employed; but for the purpose of illustration it is herein described in
connection with novel cord knotting devices, and it will be understood that when
wire is to form the band material, a twister will be substituted for said knotting
devices and suitably connected with the gearing:
The Invention consists in mounting the binder arm or needle upon a rocking
frame or support, and causing it to rock inward, toward, or over the grain table,
descend, carrying the band around the gavel, which it seperates from the incoming
stream of grain, and then rock outward and discharge the bound bundle; in
mounting the binding arm and band securing mechanism to rock or oscillate in
unison, and so actuating them that the gavel is gathered and encircled by the

page_text: descent of the binder arm at the end of the inward traverse, and the ends of the
band united by the operation of the band securing mechanism as the arm is
pushing the gavel before it, and towards the discharging point on the outward
traverse; in a compressor of improved construction to compress and give form to
the bundle, and to relieve the band and band applying devices of this duty and of
the strain incident thereto; in mechanism for causing the needle or binder arm
and compressor to act upon the grain; in arranging and causing the pinion of the
band fastening devices to be rotated by a toothed surface at permanent distances
from the axis of movement of the swinging support of the binder arm or needle ;
in an improved tension device acting upon the cord as it runs from the spool to the
binder arm; in the mechanism by which the various movements are produced and
controlled, and in details and combinations hereinafter explained.
The immediate supporting frame of the binding mechanism is secured to the
stubble side of the harvester elevator, either fixedly or in such manner as to be
capable together with the grain receptacle of adjustment there along to compensate
for varying lengths of grain, as customary in this class of machines. Mounted in
the vertically trending standard or standards, of which there may be one at the
front and anotlier at the rear of the machine, is the main shaft of the binding
attachment, and driven by gear in any suitable manner from the harvester.
Upon the journal shaft at the top of this frame and below the plane of
the receptacle or binding table is pivoted the post frame, consisting of a
vertical post at the front of the machine, an arm subtending the binding table
and supporting at its near end beneath the slot in the grain table, a slotted
block and binding head, and an overhung arm terminating above the slot in the
grain table, and supporting there the binding arm and compressor, which are
actuated as will be presently described by means of a rock shaft having its
bearings in said overhung arm.
From the foot of the post frame projects a heel piece, which by means
of a link is connected with a crank or wrist pin upon the face of the gear on the
main shaft, so that as the gear revolves, the post frame carrying with it the
binding arm and compressor and the binding head may be rocked or tipped upon
its bearings, and the binding arms caused to traverse the grain table alternately in
towards the elevator head or grain chute, and out towards the stubble side.
To the same wrist pin is attached another link or connecting rod, which at its
top is pivoted to the crank arm of the rock shaft actuating the compressor, and
this as it is drawn down by the revolution of the gear forces down the binder
arm, and causes it to pass through the grain, and when it rises lifts also the
binding arm.
As the wrist pin and connecting rod are inclined away from each other their
dead centres will not correspond, and their arrangement is such that the motion of
the wrist pin is slightly in advance of that of the connecting rod. The binding
arm therefore commences its descent, due to the action of the wrist pin, slightly
before the termination of the inward traverse due to the connecting rod, and with
the supplemental downward motion from the inward tipping of the post frame,
whereby it is caused to descend quite rapidly, and as it commences its outward
traverse it is brought home to the binding head and delivers the cord thereto.
The downward motion of the wrist pin still continuing, the binding arm would
be jammed against and tend to drive past the binding head, and this being in its
way one or the other must break. To prevent tliis and still allow it to lie snug
against the binding head during the knotting or tying operation, and at the same
time providing for it to grasp the end of the cord when it again rises, it is made in
two sections, hereafter called Nos. 1 and 2, the latter being secured to the side
of the other by a slot and pin connection, and also further secured to slide
longitudinally of said section when moved along the slot.
The section No. 1 is jointed to the rock shaft in such manner as to be
permitted a limited vibration thereon, and pushed down to the extreme of its
limits in its normal position by a strong spring interposed between it and its

page_text: actuating crank, and the heel of the section No. 2 is connected with said crank by
means of a link.
When the nose of the binding arm comes against the binding head and is
stopped, the spring will yield under stress and take up the further motion of the
crank as to section No. 1, which will therefore be held steadily against the binding
head;
but as to section No. 2, the crank continuing its motion will push it down
upon the pin and cause it to slide along the other, and thus open a jaw which it
carries at its end away from a converse jaw on the end of section No. 2, to scize
the cord afresh upon the succeeding rise.
In order to secure a clean separation of the gavel from the incoming stream of
grain, a cap is placed over the binding arm and advisably pivoted upon the same
pin which unites the sections of the latter.
From the cranked heel of this cap a link proceeds to the slotted crank or bracket
fast to the rock shaft, and takes therein by means of a pin which carries an anti-
friction roll. Upon the overhung arm is also fixed a cain of segmental shape, and
in such relation to the bracket that the roll may travel upon its periphery.
When the binding arm is raised at the termination of the inward traverse, the
roller is carried by the action of the crank or bracket up to the curved crest of the
cam, and the cap or separator arm, hereinafter called the cut off, is closed and held
against the binder arın, and the shape of the cam and motion of the post frame are
such, that it is thus firmly held until the end of the inward traverse, it has
descended with the binder arm through the stream of grain, and reached the
slotted block against which it strikes and is stopped, while the roller at the same
moment passing off the crest of the cam descends along the inner face thereof, with
a retreating movement just sufficient to hold the cut off to its position. The binder
arm however passes on through the slot in the block until it reaches the binding
head and is itself stopped, as before described.
To the overhung arın on the side away from the binder arm is fixed a bracket or
offset, and near to this the rock shaft is provided with a crank to which is pivoted
the compressor arm. A pin or anti-friction roll from the bracket takes into a long
slot in the body of the compressor arm, and guides it so that as the crank is raised
with the descent of the binder arm, the compressor is also caused to descend.
If desired a strap may be attached to one end of the binder arm, and carried
over a pulley on the end of the compressor arm and up to a strong spring,
whereby the grain may be gathered within the compass of this strap and directly
compressed thereby.
In the heel extension of the post frame is pivoted a segmental cam gear which
meshes with and gives motion to the pinion of the knotter, and also imparts the
to-and-fro motion to the knotting hook by means of the pivoted link having its
fulcrum on the block. This cam gear it will be understood may be made to drive
twisting mechanism, or by a slight modification twisting, holding, and cutting
mechanism for wire binding. Being mounted upon the rocking frame it partakes
of its movements, and is therefore always in gear with the knotter pinion. It is.
connected by means of a link with an upright cam plate pivoted near the foot of
the supporting frame upon a journal shaft, and having a cam opening or aperture
into which takes a crank and roller from the main shaft. The action of this crank
upon the surface of the cam causes the intermittent vibration of the plate in such
relation to the motion of the rocking post frame and binder arm that the segmental
cam gear and consequently the knotter is actuated in unison therewith.
The motion for tying the knot takes place sharply when the crank enters the
slot at the head of the cam-slot, at that point an inclined hanger from the pivotted
link is struck by a pin on the head of the cam plate, forcing up said link, and to
release the knot. A second roller opposed to the first is advisably employed to
steady the cam plate in its motions and make them positive.
To facilitate the delivery of the grain to the binding arm and its compression
about the waist, and to form a cradle for the reception of the incoming stream
during the binding operation links or bars are pivoted to the block, and so

page_text: connected by pins at their inner ends to curved slots in the ledges or abutments at
the bottom of the grain chute and on each side of the slot in the platform, that as
the post frame'rock's in ward said inner ends rise in the slots while their outer ends
sink with the tipping of the black; they therefore at the moment form a con-
tinuation of the chute on each side of the seat, and the binding arm passes between
them to gather and compress the gavel; but when the frame rocks outward their
motion is reversed, and they form a cradle for the incoming grain checked by the
cut off
The cord for binding is drawn up from beneath the table and carried to the point
of the binder arm; on its way it is caused to pass through a tension device com-
posed of two disks on the side of the block held together by spring pressure. It is
desirable to release the tension during the initial portion at least of the rise of the
binder arm, and to this end a short lever is fulcrumed upon the block and pivoted
along its length to the outer disk, and a beveled dog or pendant is arranged upon
one of the bars to come in contact with the end of said lever as the latter is
rocked upward near the termination of the outward traverse, and to lift it and
with it the outer disk away from the inner disk against the stress of the spring.
In order to eject the bound sheaf, should the tipping of the post frame and
binding arm be insufficient to certainly accomplish this, an ejector arm is pivoted
beneath the table to a crank from the rotating shaft, and controlled and guided at
its heel end by a link, so that as the binder arm and compressor are thrown open
it rises from beneath the table in an arbital path, moves against the sheaf and
ejects it, and then is withdrawn; a binding arm may be used in the foregoing
construction. It is composed of two parts or sections, the first of which is con-
nected to a sleeve or hollow shaft encircling the rock shaft, and having a slot and
pin connection therewith so as to be allowed a limited play independent thereof,
and also having a spring interposed there between whereby it is normally pressed
forward to the limit of the slot, but permitted to yield when it comes in contact
with the knotting head. The second section slides upon the first and is attached to
a crank upon the rock shaft so that it goes on after the first is stopped, and a
nipper jaw at its end is opened away from an opposing jaw upon the first, which
jaws are intended to seize and hold the cord. Upon the said opening jaw is a knife
or cutter which severs the cord when the two jaws are again brought together by
The sections of

the binder arm are guided in their movements past each other by a block or pin
on one which slides in a slot in the other.
An oscillating cam gear may be substituted for the segmental gear first described
and actuated by the same or equivalent means; this in its oscillation gives motion
to the pinion of the knotter, the latter consisting of a heel in which is an eccentric
cylindrical opening receiving a sleeve, and this in turn has fitted within it a
spindle formed at one end with a hook or finger, and at the other with an arm.
The heel is supported in a block secured to a cap properly mounted upon the
rocking frame, and slotted to admit the binder arm to the knotter.
An arm is pivotted to the last mentioned cap, and at the other end carries
a swivelled eye hich engages with the arm of the spindle, and by means of an off
set or anti-friction roll taking into the cam slot of the gear wheel is vibrated upon its
fixed pivot, whereby the spindle is withdrawn and advanced through the eccentric
opening in the heel to seize and draw down the bow of the knot or to release it,
the swivel eye permitting the heel to rotate without interfering with the motions
of the spindle. On the side of the heel, adjacent to the hook or finger, is loosely
fitted a ring disk having a circular inclined guide or cam, and having also a tooth
against which presses a spring secured to the aforesaid cap.
In the periphery of the cap is fitted an abutment jaw which is grooved on its
underside to overhang the finger and the inclined cam or guide of the ring disk of
the tyer.
A spring plate presses against the block of the oscillating cam gear adjacent to
the opening or slot in the cap to act upon the cord as will presently appear.

page_text: In operation the end of the cord is drawn from a spool beneath the binding
table and secured in the nippers at the nose of the binding arm so as to pass around
the bill on said nose and thence to the spool; as the arm descends at the end of the
inward traverse and encircles the gavel, it puts the cord in the tyer, clamping both
thicknesses of cord against the abutment jaw, that is, the cut end and the strand
leading to the spool.
The large loop formed by the end of the cord thus doubled and held incloses the
sheaf, as the cam gear turns it causes the eccentrically-arranged sleeve to engage with
the doubled cord behind said abutment and to carry said cord around with it,
forming a loop in said doubled cord by said motion. To insure such action the
doubled cord is clamped against the clamping arm, and near the cutter by a spring
and plate which allows the cord to be drawn through it by the pull of said sleeve
engaging therewith as aforesaid, but compels the two thicknesses of cord to remain
parallel and together between said spring and said sleeve. The rotation of the cam
gear is in such direction that the tapering or lesser part of stationary flange or
guide comes first into engagement with said doubled cord.
This takes place after the loop in said doubled cord has been formed as aforesaid,
and the engagement is with that part of the cord which is just beyond said loop in
the direction of the cutter. Said flange or guide may be held stationary by a
spring catch and lug, or by any other devices. The travel of the aforesaid sleeve
causes the doubled cord to slide up the incline of said flange until it is lifted above
the ring or circle of cord formed around said sleeve; in so doing it necessarily draws
a little more cord through the clamping jaws; the slack cord thus acquired is
presented by such lifting action to the hook and seized thereby. When said hook
is withdrawn by agencies already described it carries with it a bow of doubled cord
into the hollow wheel or pinion, the withdrawal into said pinion of the sleeve
necessarily slips the loop of cord already described upon the bow, and the draft on
the end of the bow completes the knot; the sheaf is thereby fully bound, and
nothing remains but to cut the cord and provide a supply for the next sheaf, as
already described.

"IMPROVEMENTS IN AND APPERTAINING TO AUTOMATIC OR SELF-BINDING ATTACH-
MENTS TO HARVESTING MACHINES." A communication from abroad from Herbert
D. Blakemore, of Cincinnati, Ohio.
The object of this Invention is to simplify and improve the construction and
operation of automatic or self binding attachments to harvesters, and it is adapted
to the use of either wire or cord as band material, according as either a twister or
knotter is employed, but for the purpose of illustration it is herein described in
connection with novel cord knotting devices, and it will be understood that when
wire is to form the band material, a twister will be substituted for said knotting
devices and suitably connected with the gearing.
The Invention consists in mounting the binder arm or needle upon a rocking
frame or support, and causing it to rock inward toward or over the grain table,
descend, carrying the band around the gavel, which it separates from the incoming
stream of grain, and then rock outward and discharge the bound bundle; in
mounting the binding arm and band securing mechanism to rock or oscillate in
unison, and so actuating them that the gavel is gathered and encircled by the
descent of the binder arm at the end of inward traverse, and the ends of the
band united by the operation of the band securing mechanism as the arm is
pushing the gavel before it, and towards the discharging point on the outward
traverse in a compressor of improved construction to compress and give form to
the bundle, and to relieve the band and band applying devices of this duty and of
the strain incident thereto; in mechanism for causing the needle or binder arm
and compressor to act upon the grain; in arranging and causing the pinion of the
band fastening devices to be rotated by a toothed surface at permanent distance
from the axis of movement of the swinging support of the binder arm or needle ;
in an improved tension device acting upon the cord as it runs from the spool to
the binder arm; in the mechanism by which the various movements are produced
and controlled, and in details and combinations hereinafter explained.

And Figure 13 is an enlarged view of the knot as formed..
Referring now to Figures 1 and 2, A, A', represents the immediate supporting.
frame of the binding mechanism secured to the stubble side of the harvester
elevator, either fixedly or in such manner as to be capable together with the grain
receptacle of adjustment therealong to compensate for varying lengths of grain as
customary in this class of machines. Mounted in the vertically trending standard
or standards A, of which there may be one at the front and another at the rear of
the machine, is a shaft B, constituting the main shaft of the binding attachment
and driven through the gear B' in any suitable manner from the harvester.
Upon a journal shaft C at the top of this frame and below the plane of the grain
receptacle or binding table is pivoted the post frame C', consisting of a vertical
post at the front of the machine, an arm C2 subtending the binding, table, and
supporting at its rear end beneath the slot in the grain table the slotted block D
and binding head D¹, and an overhung arm C³ terminating above the slot in the
grain table, and supporting there the binding arm E and compressor E¹, which are
actuated, as will be presently described, by means of a rock shaft E' having its
bearings in said overhung arm.
From the foot of the post frame projects a heel piece F, which by means of a
link F is connected with a crank or wrist pin F2 upon the face of the gear B', so
that as the gear revolves the post frame carrying with it the binding arm and
compressor and the binding head may be rocked or tipped upon its bearings, and
the binding arm caused to traverse the grain table alternately in towards the.
elevator head or grain chute and out towards the stubble side.
To the same wrist pin F2 is attached another link or connecting rod a, which at
its top is pivoted to the crank arm a' of the rock shaft E2, and this as it is drawn
down by the revolution of the gear forces down the binder arm and causes it to
pass through the grain, and when it rises lifts also the binding arm.
As the two links a and F3 are inclined away from each other, their dead centers.
will not correspond, and their arrangement is such that the motion of the link a is
slightly in advance of that of the link F2. The binding arm therefore commences
its descent due to the action of the link a slightly before the termination of the
inward traverse due to the link F2, and with the supplemental downward motion.
from the inward tipping of the post frame, whereby it is caused to descend quite
rapidly, and as it commences its outward traverse it is brought home to the
binding head and delivers the cord thereto.
The downward motion of the link a still continuing, the binding arm would be
jammed against and tend to drive past the binding head, and this being in its way,
one or the other must. break.
To prevent this and still allow it to lie snug against the binding head during
the knotting or tying operation, and at the same time providing for it to grasp the
end of the cord when it again rises, it is made in two sections a², a³, the latter.
being secured to the side of the other by a slot and pin connection at a³, and also
further secured to slide longitudinally of said section when moved along the slot.
The section a is joined to the rockshaft in such manner as to be permitted a
limited vibration thereon, and pushed down to the extreme of its limit in its.
normal position by a strong spring a interposed between it and its actuating
crank 63, and the heel of the section a³ is connected with said crank by means of a
link, as shown.
The joint between the link and crank may be an eccentric 6³ in order to increase
the motion of the section. When the nose of the binding arm comes against the
binding head and is stopped, the spring will yield under stress and take up the
further motion of the crank as to section a, which will therefore be held steadily
against the binding head, but as to section as the crank continuing its motion will
push it down upon the pin at a and cause it to slide along the other, and thus
open a jaw which it carries at its end away from a converse jaw on the end of
:

page_text: section a³, to cut the cord and sieze it afresh upon the succeeding rise, as will
hereinafter appear.
In order to secure a clear separation of the gavel from the incoming stream of
grain, a cap or separator b is placed over the binding arm, and advisedly pivoted
upon the same pin which unites the sections of the latter. From the cranked heel
of this cap a link b' proceeds to the slotted crank or bracket 62 fast to the rock
shaft, and takes therein by means of a pin which carries an anti-friction roll b³.
Upon the overhung arm is also fixed a cam of segmental shape, and in such
relation to the bracket that the roll may travel upon its periphery.
When the binding arm is raised at the termination of the inward traverse, the
roller is carried by the action of the crank or bracket up to the curved crest of.
the cam, and the cap or seperator arm, hereinafter called the cut off, is closed and
held against the binder arm, and the shape of the cam and motion of the post
frame are such that it is thus firmly held until, at the end of the inward traverse,
it has descended with the binder arm through the stream of grain and reached the
slotted block D, against which it strikes and is stopped, while the roller at the
same moment passing off the crest of the cam descends along the inner face thereof
until with a retreating movement just sufficient to hold the cut off to its position.
The binder arm however passes on through the slot in block D until it reaches
the binding head and is itself stopped, as before described.
To the overhung arm C³ on the side away from the binder arm is fixed a bracket
or offset C, and near to this the rockshaft is provided with a crank C¹, to which is
pivoted the compressor arm E¹. A pin or anti-friction roll from the bracket takes
into a long slot in the body of the compressor arm and guides it, so that as the
crank is raised with the descent of the binder arm, the compressor is also caused to
descend.
If desired a strap C² may be attached to one end of the binder arm, and carried
over a pulley on the end of the compressor arm and up to a strong spring C³, as
shown, whereby the grain may be gathered within the compass of this strap, and
directly compressed thereby.
In the heel extension F of the post frame is pivoted a segmental cam gear C
which meshes with and gives motion to the pinion C6 of the knotter, and also
imparts the to-and-fro motion to the knotting hook by means of the pivoted link C7
having its fulcrum on the block D.
This cam gear it will be understood may be made to drive twisting mechanism,
or by a slight modification, twisting, holding, and cutting mechanism for wire
binding. Being mounted upon the rocking frame it partakes of its movements,
and is therefore always in gear with the knotter pinion. It is connected by means
of a link d with an upright cam plate D³ pivoted near the foot of the supporting
frame A upon a journal shaft d', and having a cam opening or aperture, sub-
stantially such as shown, into which takes a crank and roller d², ds, from the main
shaft B. The action of this crank upon the surface of the cam causes the inter-
mittent vibration of the plate in such relation to the motion of the rocking post
frame and binder arm that the segmental cam gear and consequently the knotter
is actuated in unison therewith..
The motion for tying the knot takes place sharply when the crank enters the
slot at the head of the cam slot, and has just been completed when the parts reach
the position shown in Figure 2, and at that point the inclined hanger from the
link c is struck by a pin on the head of the cam plate D2, forcing up said link to
release the knot.
A second roller d' opposed to the first is adviseably employed to steady the cam
plate in its motions and make them positive.
To facilitate the delivery of the grain to the binding arm and its compression
about the waist, and to form a cradle for the reception of the incoming stream
during the binding operation, links or bars d are pivoted to the block D, and so
connected by pins at their inner ends to curved slots in the ledges or abutments d
at the bottom of the grain chute and on each side of the slot in the platform that

page_text: as the post frame rocks inward said inner ends rise in the slots, while their outer
ends sink with the tipping of the block.
:
They therefore at the moment form a continuation of the chute on each side of
the slot, and the binding arm passes between them to gather and compress the
gavel, but when the frame rocks outward their motion is reversed and they assume
the position shown in Fig. 2, and form a cradle for the incoming grain checked by
the cut off.
The cord for binding is drawn up from beneath the table and carried to the
point of the binder arm. On its way it is caused to pass through a tension device
composed of two disks e, e¹, on the side of the block D held together by spring
pressure. It is desirable to release the tension during the initial portion at least
of the rise of the binder arm, and to this end a short lever e² is fulcrumed upon the
block D and pivoted along its length to the outer disk e¹, and a beviled dog or
pendant e³ is arranged upon one of the bars ds to come in contact with the end of
said lever as the latter is rocked upward near the termination of the outward
traverse, and to lift it and with it the disk e¹ away from the disk e against the
stress of the spring.
In order to eject the bound sheaf should the tipping of the post frame and
binding arm be insufficient to certainly accomplish this, an ejector arm e is pivoted
beneath the table to a crank from the rotating shaft B and controlled and guided
at its heel end by a link e³, so that as the binder arm and compressor are thrown
open it rises from beneath the table in an orbital path, moves against the sheaf and
ejects it, and then is withdrawn.
Referring now to the succeeding Figures, G is a binding arm which may be used
in the foregoing construction. It is composed of two parts or sections g and g¹, the
first of which is connected to a sleeve or hollow shaft encircling the rock shaft, and
having a slot and pin connection therewith so as to be allowed a limited play
independent thereof, and also having a spring interposed there between, whereby it
is normally pressed forward to the limit of the slot but permitted to yield when it
comes in contact with the knotting head. The second slides upon the first and is
attached to a crank upon the rock shaft, so that it goes on after the first is stopped,
and a nipper jaw g² at its end is opened away from an opposing jaw q³ upon the
first, which jaws are intended to seize and hold the cord. Upon the jaw q³ is a
knife or cutter q* which severs the cord when the two. jaws are again brought
together by the rebound of the spring at the moment the binder arm rises. The
sections of the binder arm are guided in their movements past each other by a
block or pin on one which slides in a slot in the other.
An oscillating cam gear H may be substituted for the segmental gear first
described and actuated by the same or equivalent means.
This in its oscillation gives motion to the pinion of the knotter H', the latter
consisting of a hub in which an eccentric cylindrical opening receiving a
sleeve 2, and this in turn has fitted within it a spindle ³ formed at one end with
a hook or finger h, and at the other with an arm 5. The hub is supported in
a block H2 secured to a cap I properly mounted upon the racking frame and slotted
to admit the binder arm to the knotter.
An arm i is pivoted to the cap I, and at the other end carries a swivelled eye K
which engages with the arm h³ of the spindle h³, and by means of an off set or
anti-friction roll taking into the cam slot of the gear wheel is vibrated upon its
fixed pivot, whereby the spindle is withdrawn and advanced through the eccentric
opening in the hub to sieze and draw down the bow of the knot or to release it,
the swivel eye permitting the hub to rotate without interfering with the motions
of the spindle.

In operation the end of the cord is drawn from a spool beneath the binding table
and secured in the nippers at the nose of the binding arm so as to pass around the
bill on said nose, as in Fig. 3, and thence to the spool. As the arm descends at the
end of the inward traverse and encircles the gavel it puts the cord in the tyer,
clamping both thicknesses of cord against the abutment jaw m, that is, the cut end,
and the strand leading to the spool.
The large loop formed by the end of the cord thus doubled and held incloses the
sheaf. As the cam gear turns it causes the eccentrically arranged sleeve to engage
with the doubled cord behind said abutment, and to carry said cord around with it,
forming a loop in said doubled cord by said motion. To insure such action the
double cord is clamped against the clamping arm, and near the cutter by the
spring and plate M, which allow the cord to be drawn through it by the pull of
said sleeve engaging there with as aforesaid, but compels the two thicknesses of
cord to remain parallel and together between said spring and said sleeve. The
rotation of the cam gear is in such direction that the tapering or lesser part
of stationary flange or guide K2 comes first into engagement with said doubled cord.
This takes place after the loop in said double cord has been formed as aforesaid,
and the engagement is with that part of the cord which is just beyond said loop in
the direction of the cutter.
Said flange or guide may be held stationary by a spring catch and lug (shown
in Figure 7), or by any other devices. The travel of the aforesaid sleeve causes
the doubled cord to slide up the incline of said flange, until it is lifted above the
ring or circle of cord formed around said sleeve.
In so doing it necessarily draws a little more cord through the clamping jaws.
The slack cord thus acquired is presented by such lifting action to the hook
and seized thereby. When said hook is withdrawn by agencies already described,
it carries with it a bow of the doubled cord into the hollow wheel or pinion A¹.
The withdrawal into said pinion of said sleeve B¹ necessarily slips the loop of cord
already described upon the bow, and the draft on the end of the bow completes
the knot.
The upper end of the bow in Figure 10 is the end which the book draws. The
sheaf is thereby fully bound, and nothing remains but to cut the cord and provide
a supply for the next sheaf, as already described.
What is claimed as said Invention is,-
