Improvements in Knot Tying Devices for Wood Bundling Machines.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this 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 to knotting devices, but more particularly to a device
for tieing knots in the binding material of wood bundling machines.
The primary object of the invention is to provide an efficient device for
securing the cord or binding material which may be employed in wood bundling
machines so as to effectually prevent its slipping or dis-connection under great
pressure, such as that secured by a square or reef knot, and which will secure or
tie the knot in the binding cord or twine close to a hard and practically unyield-
ing substance or material.
A further object is to provide a simple and compact knotting device which
may be used for various purposes; which may be connected so as to operate
simultaneously with a series of devices of like character to tie a series or number
of knots in unison, and which will readily tie and secure the coarse binding cord
or twine usually employed for bundling wood and other materials.
With these and other objects in view the invention consists in the construction
and combination of the several parts substantially as hereinafter described and
then pointed out in the claims at the end of the description.

The knotting mechanism as illustrated in Figures 1 to 24 inclusive has a cord
or binding material carrier 10, which is provided with a slide 11, the latter
being arranged in a support 12, and carrying at one end thereof a clamping jaw,
as at 13, and has a bar or rod 14 pivoted thereto, as at 15. which is provided with
a clamping jaw 16 between which and the jaw 13 the twine or cord is adapted to
be clamped and fed forward from the roll (not shown) or other source of supply,
said jaws being normally pressed apart by means of a spring, as at 17 in
Figure 12. On the slide 11 may be arranged a bracket 18, which is connected
by means of a rod or link 19 to the lower end of the arm or lever 20, which latter
is arranged to swing or oscillate on the transverse shaft 21. The lever 20 may
be provided with the cam projection 22 (Figure 1) which is adapted to be
engaged at the proper time by the cams 23 and 24 arranged upon the disc 25,
which latter is secured to the transverse shaft 26, the cams being adapted to
engage the cam projection 22 and advance or force the cord carrier, and the
clamping or carrying jaws 13 and 16 forming a part thereof inwardly for the
purpose to be hereinafter explained. The cord carrier 10 is retired or brought
back to different positions by means of the cam projections 27, 28 and 29 on

page_text: he disc 30, which projections engage a sliding block 31, as at 32, the saru
liding block being slotted at both ends so as to span the transverse shafts 26
nd 21 and being provided with an elongated aperture in which is a pin 33
projecting outwardly from the lever or arm 20, so that when the disc 30 rotates,
the cam projections thereon, engaging the sliding block 31 will throw the
ower end of the arm or lever 20 rearwardly or outwardly, and through the
pitman or connecting rod 19 retire the slide 11 and the clamping jaws carried
thereby.
In order to cause the clamping jaws 16 and 13 of the carrier 10 to positively
engage the cord or twine, or be released therefrom, we may pivot a rocking block
or arm 34, as at 35, to the bracket 18. On one end of this rocking arm may be
arranged a wedge shaped cam 36 which is adapted to engage the inner edge of
the bar 14 carrying the jaw 16 so as to throw the same inwardly on its pivot,
while the reverse or open position is obtained through the pressure of the
spring 17. At or near each end of the rocking arm 34 may be arranged rods
or studs 37 and 38 which are adapted to move in the path of the collar or
bracket 39 (Figure 12) secured at or near the lower end of the pendent rod 40,
the said rod being secured to a bar 41, which may be pivoted at its outer or
forward end to a suitable support 42, and which is adapted to be engaged by
the cam projections 43 and 44 on the disc 45, which latter is secured on the
transverse shaft 26, as shown in Figure 6, in order that when the slide 11,
together with the rocking arm or block 34, is advanced so that the stud 38 is
in the path of vertical movement of the bracket 39, the cam projection 43
acting on the rod 41 will raise the bracket and tilt the rocking block so as
to tilt the bar 41 on its pivot and cause the jaw 16 to grasp the cord and carry
or advance the same forward at the proper time. On further advancing the
carrier 10, the bracket 39, through the cam projection 44 and the arm 41,
engages the stud or projection 37 on the rocking arm 34, and tilts the same to
a medium position or away from the arm or bar 14 carrying the jaw 16, so that
the clamping jaws may be released from the cord or string and permit the cord
to slip past the jaws when the latter are forced rearward or outwardly. A pin 16
projects outwardly from the pitman 19 and is adapted to engage a recess in the
spring block 47 in order to yieldingly retain the carrier in its proper position
while the loop is being formed, as will be hereinafter described.
The slide 11 of the carrier 10 has a rod 48 journaled thereon, around which may
be arranged a spring 49 adapted to retain said bar or rod normally against
rotation. On one end of the rod 48 is arranged an arm 50, which is adapted to
engage the beveled end 51 of the support 12 and lift the outer end of said
arm when the carrier is forced rearward so as to rotate the rod 48 and throw
O the lower end of the arm 52, arranged on the opposite end of the bar 48, laterally.
The arm 52 engages a block 53, which carries a pin 54, which is adapted to be
thrown beneath the lower side of the loop at the proper time to retain and hold
the same while the loop is being folded, a couple of rollers, as at 54, Figure 17,
being arranged in the jaw 13 of the carrier 10 between which the cord from the
5 source of supply is adapted to pass.
The string or cord carried by the clamping jaws 13 and 16 of the carrier 10
when moved forward is engaged by the jaws of the gripper 55.
The gripper 55. is provided with opposed jaws 56 and 57 adapted to grasp
the twine or string, these jaws being pivoted together and pressed normally
50 into closed position by the spring 58 (see Figure 14). The body of the gripper 55
is slotted so as to ride on the shaft 58, and the shaft is pierced also by the
pin 58b, which extends longitudinally through the slot of the gripper. The
shaft 58 is journalled on the end of the sliding rod 59, to be presently referred
to, and in the path of the shaft 58 is a curved guide 62, which is held on the
55 head 60. It will be seen therefore, that the gripper may move vertically up
and down on the shaft 58 when in position shown in Figure 13, but if the rod 59

page_text: is moved outwardly, then the shaft 58ª engages the curved guide 62, and partially
rotates, thus tipping up the gripper 55 to the position shown in Figure 11.
The rod 59 is longitudinally movable in the head 60, which latter is supported
so as to have a transverse or lateral movement in the frame 61, and said rod has
upon its outer or rear end springs 62ª and 63 arranged on opposite sides of a
pendent bracket 64, so that when the latter is given a longitudinal movement
the rod 59 and the gripper 55 will be forced forward or outwardly with a yielding
pressure according to the direction in which the bracket 64 is moved. The rod 59
is provided with a pawl or detent 65, having one end thereof adapted to pass
over the plate 66 on the frame 61 so as to retain the rod and gripper in a
forward position, a notch 67 being provided in the plate 66 to permit the rod 59
to be forced rearwardly when the pawl is in alignment therewith. The bracket
64 connects with an arm or bar 68 which has its inner end connected to a lever 69
pivoted so as to oscillate on the transverse shaft 70 as best shown in Figure 10.
The upper end of the lever 69 is provided with a projection 71 adapted to be
engaged by the cam 72 arranged upon a disc 73, the latter being also provided
with a cam 73, a raised portion 74 and a projecting cam 75 adapted to engage
the projection 7.1 on the lever 69 to operate the same so as to throw the lower end
thereof forward to various positions, as will hereinafter appear. A sliding
block 76 has a pin and slot connection 77 with the lever 69 and is adapted to
be engaged by the cams 78 and 79 on the disc 80, as at 81, in order to force the
lower end of the lever 69 rearward or outwardly. The yielding member 57
of the gripper 55 has a projection 83 (Figure 14) thereon adapted to be engaged
by a pin or lug 84 on the disc 85 which is secured to a rocking shaft 86. This
rocking shaft extends longitudinally of the machine, and at or near the rear
end thereof is provided with a finger 87 adapted to be engaged by a bracket or
trip SS (Figure 4) secured to the lower end of a rod 89, the latter being secured
at its upper end to one end of an arm 90, which is pivoted so as to have vertical
movement on the support 91 spanning the transverse shafts 70 and 82, as shown
in Figure 7. This arin 90 is arranged in the path of movement of the cams 92
and 93 of the disc 94 so that as the latter rotates with the shaft 82 the cams
will engage an adjustable bolt or other portion of the arm 90 and raise the
latter so as to rock the shaft 86 in its bearings.
For the purpose of positively engaging the end of the loop centrally thereof,
so as to rigidly hold the same while being folded, I may provide a needle 95
secured at one end to a block 96, which is guided on a rod or pin 97 projecting
outwardly from a support 97*. The block 96 may have a recess in the lower
portion thereof, which is engaged by the end of the cam 98 (Figure 14) secured
to the shaft 99 so that as the latter is rocked in its bearings the needle 95 will
be forced inwardly to engage the cord, while a reverse movement, or releasing
of the needle from the cord or end of the loop, is secured by the inner face of
the block 96 engaging the block 533 located on the cord carrier 10, as shown in
Figure 16. The shaft 99 is journaled in the head 60 and has a lug 100 (Figures
1 and 4) projecting outwardly from or near the outer end thereof which is adapted
to be engaged at a predetermined time by means of the lower end of a vertically
movable lever 101. This lever may be substantially T-shaped and pivoted at
one end, as at 102, to a suitable support and is adapted to be engaged by the
cam 103, shown in dotted lines in Figure 1, so that as said cam rotates the
lever 101 will be raised and through it and the lug or projection on the shaft.99
will force the needle inward so as to pierce a portion of the cord centrally of
the loop.
The head 60 is adapted to have a lateral movement in the support 61 and
for this purpose the lower end of the lever 104 (Figures 1 and 4) is pivoted to
lugs projecting outwardly from the head, while the upper end of the lever 104
is adapted to rock or oscillate on the shaft 105 of the driving mechanism. The
upper end of the lever 104, as at 106, may be provided with a roller which is
arranged in the path of movement of the cam 107, so that as the latter rotates

page_text: the arm 104 will be rocked on the shaft 105 and cause the head to move across
or transversely of the machine, the reverse movement of the head being secured
by means of a spring 108 arranged around a shaft or rod 109 and abutting against
one side of the head and a suitable stop on said rod, though the lateral shifting
of the head in both directions may be secured in any desired manner.
The block or support 97ª in which the needle 95 is arranged may be secured
to a slide 110 arranged to move back and forth in the head 60. This slide may
be provided with a projection 111 which may have its upper end slotted and
adapted to be engaged by the end of a bar 112, this bar being provided with a
pin 113 adapted to engage a projection 114 on the slide 110 so that at the
proper time the said slide may be moved either back or forth according to the
direction of movement of the bar 112. The bar 112 has a link 115 connected
rocking lever 116
thereto at one end thereof, while its other end is connected to a
(Figure 1) arranged upon the transverse shaft 70 of the driving mechanism. The
upper end of the rocking lever 116 has a projection 117 adapted to be engaged
by a cam 118 so as to force the link 115 and bar 112 rearward, and has a pro-
jection 119 adapted to be engaged by a cam 120 for forcing said parts in a
reverse direction.
To fold or double the loop upon itself, as shown in Figure 26, we may
arrange the bracket 121 so as to move with the bar 112. This bracket is adapted
to engage a pin 122 on the rod 123 when moving in one direction, while a
yielding connection or spring 124 is arranged between the same and the rod 123
to permit the bracket to move a certain distance without operating said rod.
The rod 123 may be connected by a yoke to the rods 125 and 125ª, which are
adapted to move longitudinally in the head 60 and have at the outer ends thereof
fingers 126 and 126 respectively. The upper folding finger, and rod 125 may
be yieldingly supported in the head 60, and is normally retained in a raised
position by means of a spring 127, arranged between the connecting yoke and
the outer or rear end of the rod 125, a stop or bracket 128 (Figures 11 and 12)
being arranged on the jaw 16 of the cord carrier in order to prevent the loop from
being forced laterally or to one side of a central position while being doubled
over upon itself by the folding fingers.
The gripper 55 when the loop has been doubled over upon itself is then forced
upwardly so as to pass the free end carried thereby through the folded portions.
To secure this result a lever 129 (Figure 1) has one end thereof extending
upwardly and its other end pivoted to the support 61 and intermediate of said
ends is connected to the lower end of a vertically moving connecting rod 130.
This rod is secured at its upper end to a vertically moving arm 131, which may
be pivoted to a support 132 arranged to span the transverse shafts 70 and 82.
and has a portion thereof arranged in the path of movement of the cam 133
(Figure 8) so that as the latter rotates the arm 131 will be raised and through
it and the rod 130 the outer end of the arm 129 will engage the under surface of
the base of the gripper 55 when in the position shown in Figure 13 and will
force the same upwardly, thus causing the free end of the cord held thereby
5 to be passed through the folded loop, as shown in Figure 23. The end of the
cord at this time is engaged by a nipper 134. This nipper comprises two members
pivotally held together, one of which, as 135, is yieldingly forced outwardly by
means of a spring, or otherwise, and is adapted to be engaged by means of a
cam 136 (Figure 14) on the disc 85 in order to tilt the member 135 on its pivot
O and grasp and rigidly hold the free end of the cord at the proper time. The
nipper has one of its members secured to or formed integrally with the slide 137
which is adapted to move back and forth in the head 60 and has a portion thereof
secured to the rocking shaft 86 so that the disc 85 may move longitudinally of
the device with the nipper.

In order to separate the cord after the knot has been formed, I may use any
suitable cutting mechanism, and as shown the mechanism 138 has two transversely
moving bars 139 and 139ª, each suitably supported in portions of the machine

page_text: or fold the loop upon itself places the detent or pawl 65 in alignment with the
slot 67 of the plate 66, and as the nipper 134 retires to complete the knot the
bracket 64 engages with the spring 63 on the rod 59 and through it forces the
rod 59 rearwardly and causes the gripper 55 to ride upon the slide or guide 62
so as to be restored to its normal position or that shown in Figures 1 and 11.
The cord between the knot and the cord carrier may now be separated by the
cutting device 138, as already described, at which time the bundle may be removed
in any desired manner and the cord carrier again forced forward by the driving
mechanism so as to cause the end of the same to be engaged by the jaws of
the gripper 55 when the cord carrier is again retired, thus placing the cord in
a horizontal plane as shown in Figure 11, to receive and be carried downwardly
by another bundle of wood or other material when dropped upon the same or
into suitable compressing arms, as already described.
We thus provide a simple and compact knotting device which will secure or
tie the knot with binding cord or twine close to a hard and practically un-
yielding substance or material and of such a nature as to prevent its slipping
or disconnecting while under great pressure.
In actual practice it is my intention to provide a series of knotting devices
when desired and connect the same so as to operate in unison in order that wood
may be bound in lengths and then separated into the proper sized bundles or
packages. Only a single device is shown and described herein, as this is deemed
all that is necessary, and ordinarily where a series of knotters are employed the
driving mechanism shown at the upper portion of the device may be located at
either or both ends of the bundling machine and provided with single connections
with the various working parts in order to simplify and reduce the number of
parts to as smail a number as possible. It will of course be understood that the
knotting device may be used singly or in connection with similarly constructed
or other devices if found desirable.
In Figures 29 and 30 the cord carrier is substantially the same both in
operation and in construction to that described in the other form, except that
the disc 30 on the shaft 26 is provided with two cam projections 147 and 148
respectively, instead of three as previously described, so that one less movement
of the sliding block 31 is secured, as will hereinafter appear. Here the string
or cord carried by the clamping jaws 13 and 16 of the carrier 10, when moved
forward, is received by the gripper 149, which comprises two spring-pressed
gripping jaws 149ª and an arm 150 pivoted to the inner end of the rod 151,
and on which arm the gripping jaws are arranged. The arm 150 is normally
pressed upward by a spring as 152, or otherwise, and on the arm 150 may be
arranged a plate 153 having its forward edge beveled and adapted to engage the
inner surface of a bar 154, said bar extending transversely of the machine and
being adapted to operate the arm 150 of each knotter in unison. The bar 154
may be connected to a rod 155, which slides in the bracket or support 156
and has its outer end engaged by an arm or lever 157, which is pivoted so as to
oscillate on the transverse shaft 158 and has a projecting end provided with a
set screw or other engaging portion adapted to be engaged by the cam 159,
which is arranged on the transverse shaft 160 and is adapted to tilt the arm or
lever 157 on its pivot and advance the bar 154, and through the plate 153 force
the rod 151 and arm 150 forward and downward into the position shown in
dotted lines in Figure 29, the said bar 154 being returned to its normal position
by means of a spring 161, having one end thereof secured to the bar and its
other end secured to a bracket or support 156, the sliding rod 151 being returned
by means of a spring, as at 162. The bar or plate 163 is arranged transversely
of the support or bracket 156, and has its upper end fitting over the rod or
bar 155 and has its lower end slotted so as to span the rod 151 of each knotter,
the rod 155 being reduced in size so as to permit the bar 163 to be forced
downward by the action of the spring 164 when the arm or lever 157 advances
the rods 155 and 151 sufficiently to permit the said bar or plate 163 to slide over

page_text: he latter rod, thus preventing the rod 151 from being forced rearwardly as
he rod 155 and bar 154 are advanced, in order to cause the arm 150 to be rocked
on its pivot and forced to the position shown in dotted lines, so as to carry the
end of the string or cord below the path of movement of the clamping jaws 13
and 16 of the carrier. The clamping jaws are now advanced by means of the
mechanism heretofore described to a point substantially midway over the open-
ing A and between the compressing jaws B of the bundling machine so as to
double or form the string in the shape of a loop, as shown diagrammatically by
broken lines in Figure 29, the clamping jaws being frictionally held in this
position by a pin or lug 46 on the pitman 19 engaging a recess in the upper
surface of a spring-pressed stop or block 47, as herein before described. At this
time the loop is folded over in the form shown in Figure 25. To secure this
result the arm 165 may be pivoted to the bracket 166, projecting outwardly from
the support 156, and has its inner end 167 arranged in the path of the loop
and its other or outer end pivoted to a link, as 168, this link being pivoted to
the sliding rod 169 arranged in the bracket or support 156, and having its other
end engaged by the lower end of the arm or lever 170 pivoted so as to oscillate
on the transverse shaft 158, and provided at its upper end with an adjustable
bolt or other engaging portion, which is adapted to be engaged by a cam 171
secured to the transverse shaft 160, so that the rods or cams will engage the
bolt or projection on the lever 170 and carry the sliding rod 169 rearward, and
through the link 168 throw the end 167 on the arm 165 inward so as to fold
the loop upon itself, as in Figure 25, a spring 172 being provided to return
the arm to its normal position or that shown in Figure 29.
The upper and lower members of the loop may be doubled over by means of
the inwardly projecting forward end of the lever or arm 173 arranged upon the
carrier 10. This arm may have a portion thereof arranged in a suitable bracket,
as at 174, which may be pivoted to the slide 11, as at 175, and yieldingly con-
nected to said bracket by means of a spring 176 arranged between the bracket
and a suitable collar on said arm or lever. The outer end of the arm 173 is
arranged in the path of movement of a rocking lever 177, which latter is arranged
on the transverse shaft 21 and has a suitable projecting portion thereon adapted
to be engaged by a cam 178 secured to the transverse shaft 26, so that as said
cam rotates the lever will be rocked on its shaft and force the rod or arm 173
forward so as to tilt the same or throw the forward edge thereof inwardly or
across the face of the carrier and double the loop over to the position shown in
detail in Figure 26. At this time the sliding rods 155 and 151 are permitted
to return to their normal position, and in doing so the end of the string or cord
carried by the clamping jaws 149" of the gripper will be passed through the loop
and engaged by the nipper 179. This nipper has one member 180 slidably held
in the support or frame 156 at or near one end of which is pivoted a second or
clamping member 181, as at 182, said members having their clamping ends or
jaws normally pressed apart by means of the spring 183. The end of the
member 180 is engaged by the lever 184, pivoted so as to oscillate on the trans-
5 verse shaft 158, and provided with a projection portion 185 adapted
to be engaged by a 186 for forcing said member rearwardly and
a cam
be engaged by
with the projection 187 adapted to
its normal position. The member 181 of
restoring said member to
or inclined
one end thereof,
at 189, beveled
as
the nipper 179 has
50 and adapted to engage a beveled or inclined portion of the support 166, as at 190,
so that immediately as the arm or lever 184 is forced so as to throw the member
180 outwardly or rearwardly, the action of the beveled portion 190 upon the
end 189 will close the member 181 so as to grip the string or twine, and by a
further movement thereof the bend of the loop will move inwardly across the
55 end of the string engaged by the nipper so as to cause the two portions to slip
and interlock. as in Figure 27, and on further separation the nipper and cord
carrier will tie the knot as shown in Figure 28.

and from there drop into the compressing arms B, both of which are adapted to
open and close by suitable mechanism on the bundling machine, not shown, the
frame or support 156, as well as the frame or support 61 of the form shown in
Figures to. 24 inclusive, being adapted when desired to open and close simul-
taneously with the compressing jaws B.
The string or twine of each knotting device is carried forward by the carrier 10
so as to be engaged by the clamping jaws or block 149 of the gripper and rigidly
held thereby, at which time the jaw 16 of the carrier is released from the twine
by means of the bracket 39 engaging the pin 37 of the rocking arm or block 34,
so as to tilt the same to a medium position as hereinbefore described. The
slide 11 now retires or is forced rearward by means of the cani 147 on the disc 30
engaging the sliding block 31, which, through the pin 33, rocks the arm or
lever 20 on the shaft 21. The jaws B then.open by reason of suitable mechanism,
thus opening the forming arms C so that the wood falls downward between the
jaws carrying with it the string or twine, the latter at this time being held at
one end by the clamping jaws 149 of the gripper, and being fed from the source
of supply through or past the clamping jaws 13 and 16 of the cord carrier. The
jaws B are now closed so as to firmly compress the wood and to allow the forming
arms to close by gravity ready to receive a new supply of wood. The rod 155
of the knotting mechanism is then forced inwardly by means of the arm or
lever 157 so as to tilt the arm 150 on its pivot and force said arm and the rod 151
inwardly so that the end of the string will project upwardly, as shown in dotted
lines in Figure 29. The rocking arm 34 is now operated so as to cause the jaws
of the carrier to rigidly grip the string or twine. The cord carrier is then
advanced or moved inwardly to substantially the central vertical plane of the
compressing jaws or arms, during which movement, owing to the rigidity of
the string or twine, a loop substantially of the form of that shown by short
dotted lines in Figure 29 will be formed, the position of the clamping jaws being
at this time about midway between the jaws B. The arm 165 is now operated
by means of a lever or arm 170 through the link 168 and sliding rod 169 so as
to throw the inner end 167 of said arm inwardly and fold the loop upon itself,
as shown in Figure 25. The folding arm 173 is then operated so as to double
or fold the, members of the loop as shown in Figure 26. At this time the rod 151
will return to its normal position, and in so doing the end of the string, which
now extends upwardly, will be passed through the folded loop by the upward
movement of the arm 150, as shown in dotted lines in Figure 26, and will be
engaged by the nipper 179, which at this time is being moved rearwardly by the
lever 184 and the cam projection 186 on the shaft 160. As the nipper 179 moves
rearwardly or outwardly carrying with it the end of the twine, the carrier 10
will also be retired or forced outwardly by means of the cam 148 engaging the
sliding block 30, so as to tilt the lever 20 on the shaft 21, and through the
link or pitman 19 force the cord carrier 10 in the same direction, thus rigidly
securing the parts and forming the knot as shown in Figure 28. The string
or twine may now be separated by mechanism substantially as that already
described.
In using the term "cord" it is intended not only to include that commonly
so-called by such name, but also to include any material suitable for binding
purposes and which may be secured or tied into a knot.
It is obvious that various changes in the arrangement and operation of the
parts may be made if desired, such as that the cord carrier 10 may be made to
have a lateral movement instead of the head 60 while the loop is being folded,
or that some of the parts which are shown as being operated by gravity may be
positively operated, and that some of the parts or features of the invention may
be differently constructed or other parts substituted therefore without departing
from the spirit of my invention.

page_text: Having now fully described and ascertained the nature of my said invention
and the manner in which it is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is:-
1. A knotter, having in its organization the following characteristics: A cord
carrier movable to various positions, a movable gripper receiving the cord
from the carrier, a movable nipper receiving the cord from the gripper,
mechanism for folding the cord upon itself, a needle to pierce and
rigidly hold the loop of the cord, mechanism for completing the knot, and details
of the character described for working the above-named groups of mechanism.
2. A knotter, comprising a machine constructed, arranged and operating sub-
stantially as described in the foregoing specification, and illustrated in the
accompanying drawings.
3. A knotter, having a carrier, gripper, nipper and cord folding mechanism,
substantially as described, by which the loop is formed in the cord and the knot
tied, the mechanism being adapted to tie the knot tightly and snugly to the
bundle.
4. The general organization of the cord carrier, the movable gripper, movable
nipper, the cord folding mechanism, the needle mechanism, the means for com-
pleting the knot, and also the details as illustrated and described, which con-
stitute the above-named groups of mechanism.
