page_text: Improvements in Cord-knotting Mechanism for Grain Binders.
I, ANDREW STARK, of Chicago, in the County of Cook and State of Illinois, United
States of America, Mechanical Engineer, do hereby declare the nature of my invention
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 chiefly to the cord holding mechanism of a cord knotter. It
comprises, however, certain features pertaining to knotter bill or cord looper, and
the cord cutter, the same being related intimately to the improvements in the cord
holding mechanism.
The cord holding device which I employ consists of a cylindrical cord holding ring
revolved about the knotter bill or cord looper, having notches in one edge to receive
and carry the cord into proper position to be seized by the knotter bill or cord looper,
and by the same motion carrying the cord to a suitable clamp cöperating with said
ring to hold the ends of the cord.
In connection with this cord holder, and to render it more fully operative I employ
a breast-plate having a peculiarly formed slot for the passage of the needle or binding
arm in carrying the cord to the knotting mechanism." The form of said slot will be
hereinafter explained in detail.
«
I also employ a cord looper of the form commonly known as a bill," and I construct
it with a peculiar and peculiarly located barb or tooth on the stationary jaw, as and for
a purpose which is hereinafter fully explained.
Other minor peculiarities are hereinafter fully explained and described.
In the drawings Figure 1 is a vertical section parallel with the plane of the needle,
showing the knotting mechanism in elevation. Fig. 2 is an outer side elevation of the
knotting mechanism, the needle being omitted. Fig. 3 is a front elevation showing the
needle and the binder frame as well as the knotting mechanism. Fig. 4, is a sectional
plan of the breast-plate and cord holder, the section being made through, Figure 1.
Figure 5, is a plan of the cord holding ring in position on the breast-plate, showing
the cord looper and cord in the initial position of the former. Figure 6, is a detail
plan of portions of the breast-plate, cord holder and cord looper, at a stage of
the knot-tying process subsequent to that shown in Fig. 5.
Fig. 7 shows in

page_text: perspective the cord looper and cord at a stage of the tying process subsequent to
that shown in Fig. 6. Fig. 8 is a perspective of the breast plate, cord looper and cord
at a still later stage. Fig. 9, is a plan of same paris as shown in Fig. 6, at the final
stage in the revolution of the looper. Fig. 40. is a detail plan of the looper jaws-the
remainder of the device being broken away, showing the cord in the position just
prior to stripping off the loop and finishing the knot. Fig. 11, is a similar view of a
common form of looper, the cord being shown at the instant after the loop is stripped
off, and before the knot is tightened. This view is designed to illustrate the difference
between the common form of looper and my improvement. Fig. 12, is a plan of a
pinion which receives intermittent motion, from the knotter actuating wheel, for the
purpose of driving the cord-holder ring. Fig. 13, is an elevation of the cord looper
and its bearing in the knotter frame. Fig. 14 is a section through y—y—y Fig. 2.
with a portion of the cord-holder ring shown in perspective and broken away, to
illustrate the action of the cord holder clamp. A, is a binder frame. B. is the knoiter-
frame, which includes the hanger B, and the breast plate B2, secured to the lower end
of the hanger. C. is the needle or binding arm, C₁ is the needle rock-shaft. D. is the
binder driving shaft. E, is the Knotter actuating wheel. F, is the discharger. G, is
the binding cord. H, is the cord looper. The hanger B' has the journal box 110 for the
binder driving shaft D, on which it is thereby hung in the usual manner. It has also
the journal box B₁ for the shaft or spindle h, of the cord-looper H, said journal box
and said spindle, being set oblique to the plane of the shafts C. and D. and inward
therefrom. The hanger B has the breast plate B2 secured to it by the bolt 6 at the
outer forward corner, and by the bolt at the inner side near the needle slot. The
breast-plate, it will be understood, is secured to the binder frame, at the inner end in
the usual manner. This connection it is not necessary to show in the drawings. The
cord looper H, is actuated in the customary manner, by the gear segment E¹ on
the knotter actuating wheel E, said segment meshing with the bevel pinion H³ on the
cord looper shaft. The breast plate 13 has the usual slot for the passage of the
needle in carrying the cord to the looper. The form of said slot is varied from that
which is customary, in that it is so shaped as to produce the tongue B standing
transversely across the general direction of said slot and terminating substantially in
line below the looper spindle h, and having the obliquely curved edge 20 on the
inner side.
R, is the cord-holder ring. It is an open ring, being, in effect, a short cylinder
having the equispaced notches on its upper edge, and the bevel gear rim R, on its
outer surface at its lower edge. It encircles the cord looper H, its axis being
preferably about parallel with that of the looper spindle-and being therefore inclined
upward at the inner side-i.e. the side from which the needle advances toward the
bundle. It is supported by the shoulders 131 and B2 on the breast-plate 32 and the
shoulder B on the hanger B'. It is got into place on these three bearings, by
being first hung upon the bearing B before the breast-plate is secured to the hanger,
and the breast-plate is then brought up into place under it, while it is adjusted upon the
bearings 13B, and the breast-plate is then fastened by the bolts 10, . The three
bearings thus afforded the ring R, are in the circle of said ring, the bearing BB
being preferably about diametrically opposite, so that none of the intervals or ares
between said bearings exceeds 180° of the circle of said ring. This causes the ring to
be accurately centered and incapable of shifting its centre when placed in position of
said bearings, upon which it is then adapted to be revolved about its said centre by
means of the bevel pinion J, which meshes with the gear rim R on the ring R. Said
pinion J, is fixed on one end of the shaft j. which is journaled in the bearings 113
and B on the hanger B and receives motion through the bevel pinion J¹ fixed on its
upper end and meshing with the gear segment. E on the knotter actuating wheel E.
The pinion J meshes into the ring R' at a point just over against the bearing B, so
that when said pinion is in place the ring is securely held in its true place by being
bound between the bearing and the pinion, and thus, in addition to the bearings B21 B
the pinion J becomes a means of centering the ring R. The pinion has two delay
surfaces j¹, directly opposite each other. Said delay surfaces cooperate with the delay

page_text: surface on the knotter actuating wheel E, to hold the pinion and its shaft and the
pinion and the cord-holder ring R, stationary, except while the segment E² is
engaged with the gear teeth of the pinion J. Said holder ring, therefore stands at
rest except during a small part of the revolution of the knotter actuating wheel E, and
the pinions J and J make only half a revolution for each full revolution of the wheel E.
The pinion J. by such half revolution, is adapted to rotate the ring R, the distance
between consecutive notches ». It is very desirable to obtain the necessary
movement of the cord holder ring, in the shortest possible time. By using the
pinion with two delay surfaces and making the pinion J large enough so that a half
revolution gives the necessary movement to the ring R, I am able to get the motion
in the same time and with teeth double the size on the gear segment E² and the
pinion J¹, as I could. if an entire revolution of said pinion J were made necessary.
By placing the axis of the cord looper H oblique to the plane of the axes of the
knotter actuating wheel E, and the needle C, it is made possible to place the cord-
holder ring at right angles to the axis of the cord looper so that the jaws of the latter,
revolve in a plane parallel to the ring R, and at the same time to locate the breast-
plate B close up under the looper jaws and bring the tongue B20 over which the bundle is
suspended and by which the position of the cord when the looper seizes it, is determined
as nearly as possible in line with the axis of the looper: thereby reducing to a minimum,
the length of cord intervening between the bundle and the looper and so enabling the
machine to tie the knot closer to the bundle than would otherwise be possible. If the
axis of the looper were located as usual in the plane of the axis of the needle and
knotter actuating wheel, the result above set forth could be attained only by greatly
enlarging the ring R-thereby sacrificing compactness or by changing the direction
of the plane of said ring R, and sacrificing the advantage of that direction.
The looper H, is of the form commonly called a "bill," comprising the lower or
fixed jaw H, integral with the spindle and the upper or vibrating jaw 2 pivoted in
the fixed jaw, and passing through it and having the heel FI20, for a purpose hereinafter
explained. The fixed jaw H', has the stop shoulder H resting against the underside
of the bearing B, and the heel H20 of the vibrating jaw H2 is of such length as to
protrude up above said shoulder when the jaw is closed, but to be flush with it when
the jaws are widest open. The under side of the bearing B, against which the
shoulder H rests is formed as a cain surface B B 13:12 B1, to control the action
of the vibrating jaw H2 as hereinafter explained. The upper jaw His narrow-being
scarcely more than a blade, overhanging the lower jaw H from the spindle to the
point. The lower jaw has the spur or barb H on the upper surface of said jaw
extending from the point as far back as possible without the cord being received.
behind it. Said barb is located on one side only, of the upper jaw, and that, the side
on which the cords cross in forming the knot, i.e. the forward side, considered with
reference to the rotation of the bill. The function of this barb will be hereinafter
explained.
L. is the cord clamp, which is in the form of a bell-crank-lever, the arm L² being
the clamp proper, and the arm L' serving to receive the pressure of the spring,
whereby the grasp of the clamp upon the cord is made somewhat yielding and
susceptible of being regulated and adapted to varying sizes of cords. The clamp is
secured to the hanger B by the stud bolt P, which is fixed to the hanger, and passes
through the end of the arm L. The spring is coiled around the bolt outside the
arm and retained by the nut 13 on the end of the bolt P. The arm L' extends from
the bolt, down alongside the hanger B', and the lower edge of said hanger becomes
a fulcrum over which the clamp may rock as a lever as seen in Fig. 14, while the
arm L extends under the hanger in an oblique curve agreeing with that of the holder
ring R, and has on the under side two wings L L with an intervening furrow thus
forming a saddle-like structure which strides the notched ring R. for about 90° of its
course. The inner wing L has the notch 10, to receive and guide the cord as
hereinafter explained.
N. is the cord cutter. It is a knife or chisel formed integrally with a spring arm N¹
which is secured to the frame by the bolt 6 which fastens the breast plate B² to the

page_text: hanger B. It may be secured at any convenient point on the frame, the more distant
from the knife N. the better, since the length of the said spring arm N is the radius
of the curve in which the cutter moves in approaching the cord, and the longer that
radius, the more direct is the stroke. From the point of fastening to the frame, the
arm N passes under the ring R, and then up through it sloping up, toward the edge
of the knotter actuating wheel E, on which is provided the cam. E, protruding suffi-
ciently to engage the spring arm N on its sloping surface, and depress it and the
knife N at the proper time to sever the cord as hereinafter explained.
The knife N. stands within the ring R. and preferably quite close inside of the inner
wing 10 of the clamp L standing when free from the cam E, above the notch 12, and
when depressed, by the cam, passing down past said notch.
It may be curved to fit close to the said wing, and in that case it may act in
severing the cord, with a shearing effect against the lower edge of the notch 120.
But this is not necessary since as will hereinafter appear, it acts upon the cord while
the latter is drawn tight, and will sever it without the aid of another edge.
The action of the above described mechanism is as follows:-
At starting, the end of the cord is secured in the holder, by being grasped between
the ring R. and the clamp 12, the running cord being outside the ring, and passing
thence back through one of the notches, over the tongue 1320 of the breast-plate B²
and thence to the eye of the needle. When the needle rises and carries the cord
around the bundle, it passes through the slot 2 of the breast-plate B², and enters the
ring from below near the inner.edge, passes through it, and overhangs the outer
edge, as shown in Figure 1, 3 and 4. In this process the running cord is carried
through the slot ², and encountering the transverse tongue B20 is laid across it, and
thence extends alongside the fastened end of the cord into the notch r, as shown in
Figure 5. The slope of the tongue B20 on its inner side 20, tends to cause the cords
lying across it, to slide toward shank or spindle of the looper H, as the cord is tightened
around the bundle. The looper bill at this stage, stands at rest in the position shown
in Figures 1 and 5, pointing obliquely outward and downward toward the plane
of the cord, and with the point a little lower than the cord as the latter runs from the
tongue B20, to the notch, as shown in Figure 1. At this stage the gear segment E²
on the knotter actuating wheel E, engages the pinion, and the ring R. is thereby
revolved one sixth of a revolution-the distance between the notches from right
to left, carrying the double cord which lies in the notch r, toward the spindle or shank
of the looper H and into the clamp L2, and stops, leaving the cords running from the
tongue B. over both jaws of the looper bill, and into the clamp. Meanwhile, the
looper H. has started, the gear segment E having come into engagement with the
pinion 3, and the axis of the looper being inclined toward the cord as the latter is
stretched from the tongue B to the clamp L2, and the bill or jaws of the looper being
about at right angles to the axis, the revolution of the said looper carries the jaws
upward behind the cords and gathers the latter into the angle formed by the shank
and bill of the said looper, and when the looper has completed about one sixth of its
revolution the position of the bill, holder and cords is as shown in Fig. 6., the relation
of the cords to the bill having changed about 135°-the revolution of the looper bill
toward and past the cord having caused part of the change, and the revolution of the
holder ring R in the opposite direction having caused the remainder of the change. The
looper now continuing its revolution the upper jaw, which hitherto has been kept down
upon the lower jaw by the strain of the cord across it, is forced up, by the engagement of
its heel H20 under the eccentric portion B of the cam on the bearing B, and the bill
continues to stand open while the heel H20 passes over the flat portion B12 of said
that is to say until the bill reaches a position about 270° from the starting point-
seen in Fig. 7. At this point it encounters the cord ends as they are stretched across
from the clamp, to the looper shank, and the said bill at that point receives said cords
between the open jaws. The cords at this stage are stretched tight from the point
where they are drawn around the looper shank, to the point where they enter the
clamp, and their being in the exact position necessary to be received by the
open jaws
is ensured by means of the notch 20 in the inner wing L of the clamp L², the cords
cam,

page_text: having been guided by the sides of said notch into its angle or end, as the ring R.
carried them into the clamp. Up to this point it will be evident that the cord needed
to encircle the looper jaws may be drawn from the portion of cord surrounding the
bundle, but at this stage the cords being crossed on the looper bill and drawn light,
no more cord can be drawn from that source; also it will be seen, that in the further
revolution of the looper, the point at which the cord leaves it moves away from the
point at which the cord is held in the clamp, and that therefore some further cord must
be yielded from some source to permit any further revolution without breaking the cord.
This necessary cord is partly furnished by the closing of the jaws of the looper which
occurs at this stage, shown in Fig. 8, the heel H" of the jaw H2 passing off the flat
portion B12 of the cam, and falling into the recess 13 and thereafter, to the finish,
running over the concentric portion 13110 and so remaining stationary with reference
to the lower jaw, H.
And further cord needed is drawn through the holder, the spring yielding
sufficiently for the purpose of allowing the cord to slip through between the ring R,
and the clamp L².
The bill is held very firmly closed by the cords which encircle it while it continues
its revolution drawing the cord as described to the position shown in Fig. 9, where
it comes to rest, the cords being stretched as tightly as they will bear without breaking,
from the clamp to the looper shank. At this point the cam E has come into engage-
ment with the spring arm of the cutter, and depresses it so that its cutting edge
strikes and severs the taut cords between the holder and the looper, inside the ring R.
The cord between the looper bill and the bundle, has been drawn over the inner
sloping edge 20 of the tongue B20 while the looper has been making its revolution
up to about the point where the opened jaws receive the ends of the cord. At about
that point the cords between the bundle and the looper were carried around the point
of the tongue B320 and swung over into the portion of the slot 62, and thereafter
the cords run together from the knotter bill to the bundle over the oblique curved
edge of the slot -the direction of said portion of the cords being slightly oblique
to that of the jaws of the looper in their position of rest.-Figures 5. and 8. During
all the first stage therefore, the tongue 120, tended by virtue of the slope of its eige
to keep the cords close up to the shank of the bill, notwithstanding any swaying of
the bundle which might tend to dislodge them..
During the latter stage, after the cords are crossed on the bill, and the knot is ready
for completion by stripping the loop off the jaws over the ends of the cord held therein,
the guiding edge of the part of the slot 62, gives direction to the strain which
the cord receives by the pressure of the discharger F, against the bundle.
Examining Figure 8, it will be apparent that if the knot were stripped from the
bill by a strain applied to the cords, in the direction of the dotted line v, r,
such strain would tend to pry open the jaws and release the ends g', g, and so,
prevent the formation of the knot, and that such tendency will diminish as the direc-
tion of strain is shifted toward that side of the bill on which the cords are crossed;
also, that the resistance to the stripping will be least when the strain is applied approxi-
mately in line with the jaws. In order therefore to avoid prying open the jaws, and at
the same time strip the loop from the jaws as easily as possible I form that part of the
slot which is beyond the looper-the part so that the edge 122 over which
the cords are drawn in the discharge of the bundle, is at that side of the bill on which
the cords are crossed,-which is the side toward the vertical plane of the needle; so
that when the looper completes its revolution and comes to rest in the position shown
in Fig. 9, the cord is pulled slightly sidewise and downward on the bill by the pressure
of the discharger against the bundle, thereby tending to hold the vibrating jaw H2,
down upon the ends of the cord, until the loop has been stripped off over the closed
jaw of the looper. The case of stripping is also furthered by the fact that the jaws
point downward-the axis being oblique to the plane of the axes of the needle and
the knotter actuating wheel.
In the process of stripping off the loop, the presence of the barb has the effect
to cause the knot to finish at a point on the cord nearer to the bundle than it other-

page_text: wise would. This will be understood by inspection and comparison of Figures 10 and 11.
When the looper comes to rest in the position shown in Figure 9, and the process of
stripping the loop and finishing the knot begins, the strain applied by the discharger
reaches the loop through the cords g., and tends to tighten the loop, around the jaws,
and the latter being tapering, tends also to slide the loop forward that is toward the
point of least circumference, and as the loop slips toward the point, the ends of the
cord held under the upper jaw, also slide in the same direction. Thus as the loop
becomes smaller, as it is drawn toward the point, the point of cord grasped by the
upper jaw remaining the same, all the cord taken out of the loop, as the latter tightens,
passes into the band, and slackens it by that amount. When the form of bill is the
common one shown in Fig. 11, without the barb, the process just stated continues
until the loop slips off the point of the bill, the ends of cord being at that instant
grasped at the last possible holding point of the bill, and the loop being as small as
the circumference of the bill at the last point at which it could remain on the bill.
This situation is illustrated in Figure 11. When, however, the barb His employed,
the ends grasped under the jaw H2 can not slip forward further than such barb, and
as the loop continues to slip forward, and diminish in size, the cord subtracted from
it passes equally into the band and into the ends. And the band, when the knot is
finished will be shorter than in the absence of the barb, by one half the difference
between the lengths of the cord which enters into the loop in the position shown in
Figure 10 and the length of cord in the loop in Figure 11.
From the position in Figure 10, the loop is drawn off and tightened, by the
continued pressure of the discharger against the hundle, and the ends yg are pulled
out of the loop and then slip lengthwise from under the jaw A2, being drawn around
the barb H, and the bundle being entirely free is discharged. Meanwhile the needle
retiring carries the running cord back through the next notch », in the cord holder
ring R, and down over the tongue B20 and leaves the cord as at starting ready for the
next bundle, and all parts come to rest in the initial position.
The detached ends of cord held in the clamp are cast out when the ring R advances
another stage in making the next knot.
K, is the stripper, whose function is to strip the bundle off the discharger and
prevent it being carried on around the upper arm of the binder frame. This part is
commonly made rigid with the breast plate as an outward extension thereof. I have
made it hinged to the breast plate and provided it with a spring tending to keep it
folded down toward the deck against the bundle. The reason and advantage of this
construction will be hereinafter explained. It consists of the rock shaft K', journaled
in the lugs B330 on the breast plate, and having the two parallel arms K K². Around
the shaft Kis coiled the spring k, having the loop by which it is stopped against
the breast-plate, and having the ends hooked around the arms K³, K, as being
adapted to act as a torsion spring to force the arms down and inward against the
bundle.
The effect of this construction is that the bundle will be discharged as soon as the
discharger behind it has, by forcing it against the stripper lifted the latter far enough
from the deck to allow space for the bundle to pass out under it. When the stripper
is rigid with breast plate, it must be so situated as to allow room for the largest bundle
to pass.
A small bundle is thereby allowed to be carried by the discharger, farther.
than necessary, and is brought against the stripper at an angle unfavorable for
stripping, and requiring more force to strip it. The spring-actuated stripper which
I provide adaps itself automatically to all sizes of bundles, and strips each at the most
favorable point.
