"IMPROVEMENTS IN THE CONSTRUCTION AND ARRANGEMENT OF
MACHINES FOR GLEANING, ELEVATING, AND BINDING INTO SHEAVES CORN AND
OTHER CUT CROPS." A communication from abroad by Moses A. Keller, of Brock-
port, in the United States of America.
The said Invention consists in certain improvements in the construction and
arrangement of machines for gleaning, elevating and binding into sheaves corn and
other cut crops, and will be best understood by reference to the accompanying
Drawings, in which the nature of the mechanism employed is clearly shown.
Figure 1 is a perspective view of the front of the combined machine; Figure 2
is a similar view of the back thereof; Figure 3 is a plan; Figure 4, a back view;
Figure 5, a detached view of a portion of the mechanism; Figures 6 and 7, are
cross sections; and Figure 8 is a detached view of a portion of the elevating band.
The same letters of reference indicate like parts in all the above mentioned
Figures.
The main frame of the machine is composed of the end pieces A constructed of
wrought iron, and the sill pieces B, C, and D, which may be of wood; the main
frame is rectangular in shape and in two parts, that part thereof which is chiefly
composed of the sills B and C being lifted above the wheels, and that part which
is comprised between the sills C and D, and which is partly vertical and partly
horizontal is arranged substantially on a level with the axis of the wheels. The
foot pieces A are, preferably, composed of single pieces of wrought iron bent to the

page_text: required shape as shown in the Drawings, and securely bolted to the sill pieces
B, C, and D. The whole of the operative mechanism of the machine is mounted
upon this frame which is supported upon the wheels E and F, the wheel E being
the driving wheel mounted upon the shaft, which should extend the whole length
of the main frame, and which has its bearings upon suitable brackets mounted
upon the end of the latter. The said wheel is loose upon the said shaft, but is
caused to engage therewith by a ratchet and pawl, which, when in gear, permit
the said wheel to revolve backwards freely and cause it to engage with the shaft
when the machine is advanced; F is the grain wheel.
The horses necessary to propel this machine are attached by means of a tongue
or thills C, which are secured to the front sill B of the main frame. In the
operation of this machine it is sometimes desirable to tilt the front end upward or
downward, so that the gathering devices shall run at a greater distance from, or
nearer to, the surface of the ground, and to effect the desired object the tongue or
thills G is or are hinged to the front sill B, as shown in Figure 1. From the said
thills or tongue a slotted arm H is extended rearward along the side of the frame A,
and is there connnected with the bell-crank lever I which is provided with a latch
and segment rack J, whereby the frame may be tilted at the will of the driver
and locked in any desired position. Two brackets K are attached to the under side
of the front sill B, and depend therefrom as shown, and at their lower ends they
have the bearings for the cylinder L, which is provided with a series of curved
projecting teeth 1. This cylinder L has imparted to it a rotation in the direction
of the forward movement of the machine, and the teeth 7 gather the grain as it lies
upon the ground, moves the same a little backward towards the elevating device,
and thereby tends to straighten the straws which lie obliquely, thus rendering thein
all more nearly parallel, and placing them in a more favorable position to be taken
up and elevated. The cylinder L is provided at one end of its shaft with the
wheel M, which is preferably a sprocket wheel, and is driven by a chain from a
similar wheel on the axis of the main driving wheel E. It is preferred that the
cylinder L should have about two revolutions to each revolution of the said driving 3
wheel, although that particular speed is not essential.
There is attached to the sill B a slotted apron B', which depends therefrom, and
the lower end is turned forward beneath the cylinder L, the teeth 7 passing through
the slots of the same.
The endless elevator is composed of a series of belts or chains N, N, which above 3
pass over a roller O, the shaft P of which is mounted in bearings supported by the
sill C, below which the said bolts or chains pass over a similar roller Q, which is
supported at one end by a bracket R projecting from one end of the frame A, and
at the other end by a bracket S which is pendant from the sill C. The shaft of
the said roller is mounted in moveable boxes attached to the said bracket, and 4
the said boxes are retained in position by springs U or equivalent devices, whereby
the roller is continually depressed and the belts N kept tight, whilst at the
same time the roller Q is capable of being clevated when in the progress of the
machine it comes in contact with some obstruction over which it is necessary to
pass, thereby avoiding the breaking of any part of the machine.
4
The elevator belts or chains N, N, are each provided with a series of projecting
fingers n, whereby the grain is taken from the ground and carried upward above
the upper roller O, and is delivered to the receptacle V wherein it is bound. In
-practice it is preferred to use chains composed of square links, similar to those
shown in Figure 8, a portion of the said links being provided with the fingers n, 5
as shown in the said Figure.
The use of the said chains permits of the employment of sprocket wheels upon
the shafts P, Q, instead of rollers. And a further advantage of always keeping the
said chains in their exact positions is obtained, no slipping being possible. The
teeth of the respective chains are all in line and act uniformly in lifting the grain. 5
Above the elevator, and extending down in front of the same, there are a series of
yielding grain compressors W which extend downwards, and at their lower ends

page_text: are attached to the lower edge of tho apron B¹, and act as guards to retain the
grain in contact with the fingers n as it is. being elevated. The elevator chains
or belts move upward with a speed about equal to the revolutions of the
cylinder L, so that the gathering teeth and the fingers n upon the clevator on
their proximate side move with the same speed, and therefore co-operate in raising
all the grain from the ground and lifting it to a point behind the guards W. The
elevator is conveniently driven by the same chain, whichi: passes over the wheel M
to drive the cylinder L, but in order to change the direction of the rotation
for the elevator the said chain does not pass over a wheel upon the shaft P, but
over a wheel attached to the tooth wheel X which is in turn geared to the wheel Y.
upon the end of the shaft P, so that the cylinder L and the elevator are driven at
uniforin speeds, but in opposite directions. The travelling of the elevator in a
direction opposite to the rotation of the main wheel E causes the teeth m in their
movement round the roller Q to move along the ground in the direction of the
forward movement of the machine, and thereby prevents the escape of any grain
lying upon the ground in the path of the machine.
In machines of this kind it is necessary to provide for the inequality in length
of the straw to be elevated, but it is not necessary that the entire elevating device
should be equal in width to the length of the longest straw. The main frame is
therefore extended laterally beyond the limit of the elevating device to a sufficient
distance to enable the longest straw to pass up between the sills B and C, and
within the end of the frame A on the grain side of the machine, as shown in the
Drawings. When a machine of this description is used to gather and bind grain
immediately in the rear of the reaping machine, so that the grain is gathered and
bound as rapidly as it is cut, the position of the grain wheel in respect to the
remainder of the machine is not material, but when, as is frequently desirable,
grain is suffered to lie upon the ground for several days after being reaped, it is
necessary that the grain wheel of the gathering and binding machine shall be so
placed with respect to the machine that on each succeeding round the said wheel
shall not travel upon grain that has been cut and left lying upon the field. To
accomplish this the grain wheel F is placed close to, or in rear of, the outer end of
the elevating device, and at some distance within the outer limit or end of the
main frame, as shown in the Drawings.
The clevator N acting continuously would deliver a continuous stream of grain
to the receptacle V and the binding arm would be obliged to pass through this
continuous stream of grain, an operation which has always been attended with
difficulty, and to avoid this difficulty a cut off contrivance is employed in front of
the elevator, which is for the purpose of arresting the upward movement of the
grain before it passes over the principal roller, thereby dividing the stream into
sheaves suitable for binding. This cut off mechanism is composed of a series of
plates Y', which are jointed at their lower ends to the lower edge of the apron C.
Behind the said apron, and having its bearings at one end attached to the frame A,
and those at the other end to the bracket S, there is a rocking shaft D' having.
crank arms & projecting therefroin, and each of the said arms is connected with one
of the plates Y by a link b which passes through the apron C. When the said
rocking shaft is partly rotated the plates Y₁ are turned forward against the
yielding grain compressors W sufficiently far to press the same back beyond the
points of the fingers n, so that the grain is stripped therefrom as the said fingers
pass upward, and the grain continues to accumulate between the said cut off
plates Y', and the said compressors W, thus arresting the flow and dividing the
natural stream of the grain into the sheaves for the convenience of the binding
arm. The said rocking shaft is actuated by a crank at one of its ends, and a
connecting rod E' driven by a cam upon the binding arm shaft. The receptacle
V is preferably made of two pieces of sheet metal, the front edges being secured to
the front side of the sill C, and slotted to permit the passage of the fingers n, and
the rear edge being secured to the sill D. The space F' is left between the two
pieces which constitute the said receptacle, so that the head of the binding arm

page_text: may pass below the surface of the said receptacle in gathering the sheaf and
pressing and binding the same. The wind or guard board G' is placed along the
inner end of the elevator and receptacle for the purpose of limiting the movement
of the buts of the grain towards the driving mechanism, and to prevent the wind
from disturbing the same as it passes into the receplacle from the elevator. The
driver's seat All is mounted upon a suitable support fastened to the sill C above
the driving wheel E, or thereabout, so that the weight of the driver will not inter-
fere with the balance of the machine on the main axle, and in front of the said seat
a foot board J' is placed between the sills C and B.
The binding devices are rotary in character, and are supported upon suitable
brackets J, which are mounted upon the rear sill D.
The principal shaft K¹ of the binding apparatus is mounted in boxes supported
upon and above the rear sill D, as above stated, and is driven by an open chain or
belt L', which passes over suitable wheels M¹, N¹, the former upon the main axle,
and the latter upon the shaft K'. It is desirable, however, that the shaft K' and
the operativo mechanism driven by it shall have an intermittent motion, so that
the frequency of action shall be properly adjusted to the thickness of the grain
stalks, that is to say, when the crop is heavy, bundles must be bound more
frequently than when the grain is sparse and thin. The wheel M¹ is therefore
mounted loosely upon its shaft, and on one of its faces is placed a ratchet or other
clutch, whereby it may be thrown into or out of engagement, at will. In the
Drawings is shown for this purpose an ordinary ratchet clutch, which will permit
the main wheel E to revolve backwards without rotating the wheel M¹, but will
engage and rotate the said wheel when the wheel E revolves forward.
A lever O' is pivoted. to the frame A, and is provided with a shoulder or stop h,
so located that a cam g upon one face of the wheel M' will engage with the said
shoulder or other part of the lever O' and force the ratchet clutch out of engage-
ment. A movement of the said lever upon its pivot will disengage the said cam
and permit the wheel M' to re-engage with its clutch and set the binding mechanism
in motion. A foot rod P¹ is connected with the said lever so that the driver can at
will effect the said disengagement and start the binder. A spring suitably arranged,
as will be well understood, imparts a reverse motion to cause a re-engagement of
the said lever and cam and a disengagement of the wheel M' from its driver.
The lever O may also be actuated automatically and periodically by the opera-
tion of some proper part of the driving mechanism by the application of well known
devices; or it may be automatically actuated by the passage of the sheaf when the
same is received in that way either by reason of its having been left in that way
by the reaper or by the action of the cut off mechanism hereinbefore described. The
latter node is preferred, and as a convenient method the lever O' is connected to
the crank arm at one end of a rocking shaft R¹, a crank arm or lever k at the other
end of which rests upon the receptacle V near its upper end or upon the elevator,
so that it is raised up by the passage of a mass of grain beneath it.
The upper end of the rocking shaft R¹ is supported in a bracket S₁, the foot of
which is bolted to the bracket J". The shaft K' is tubular, and the shaft T¹
extends through it, having upon one end the compressing arm U¹, and upon the
other end a pinion V'. The shaft K¹ has upon its inner end an arm W', to which
the binding arm A¹ is pivoted at some little distance from the axis of the said
shaft K'. The arm A¹ has a vibrating movement upon the said pivot, which move-
ment is limited upon a pin a upon the said arm moving within the curved slot c in
the arm W. The vibratory movements of the arm Ware determined by a cam k¹¹
which is fixed to the bracket J. There is also pivoted to the side of the arm A¹
a secondary arm m, which at the proper time is caused to be thrown forward by a
cam p, and thereby the bundle is thrown forward clear of the binding arm and
discharged from the machine. The binding arm A¹ is pointed at its outer end so
as to easily pass through the flowing stream of grain if required to do so; and upon
the side near the head a smaller finger or arm q is rigidly secured, the position of
which is parallel to the side of the head; its purpose is to catch the binding cord

page_text: as the arm revolves and carry it down through the slot in the receptacle V around
the bundle of grain and deliver it to the knotting devices which are located beneath
tho said receptacle and immediately. over the sill D. Thero is also on the head of
the binding arm and radially more distant from the finger q a roller r, over which
the binding cord also passes and in the action of the binding head conveying the
said cord to the knotting mechanism the said knotting mechanism passes between
the finger q and the roller, and the cord is thereby conveyed positively into the
knotting hook.
८
The standard 8 is also, mounted upon an outer end of the bracket J¹ to support
the cord spool and tension device at a sufficient elevation to be above the orbit of
the binding arm A¹. The cord spool & may be removed and replaced at pleasure,
and is supported upon a spindle projecting from the side of the standard s. The
said spool may be subjected to any proper tension device to prevent undue discharge
of the cord therefrom, but the device for this purpose which is proferred is a belt u,
which passes over a pulloy on the end of the said spool or connected therewith,
and over a similar pulley upon the shaft K, the belt u being adjusted to give a
backward revolution to the spool when it is being actuated by the revolution of the
shaft K, and thereby a proper tension upon the said spool is secured because when
the cord is being withdrawn from the same the said spool is caused to slip upon
the belt u, the belt being at that time moving in one direction and the spool in an
opposite direction, or the belt u will be obliged to slip upon the pulley on the
shaft K', which will accomplish the same purpose. The slipping of the belt u will
likewise take place at all times except when during the action of the binding
mechanism the binding cord is slack, at which time the belt will cause the spool to
revolve backwards and take up the slack, and thereby restore the tension upon the
binding cord.
It is necessary, however, to provide a still further tension upon the binding cord
to enable a bending arm to draw the same around the bundle with sufficient tight-
ness, because if the entire tension pressure were placed upon the belt u, which is
constantly in action, the wear upon the same would be greater than desirable.
Therefore upon the standards and in front of the spool t is also placed the tension
device v, which consists of two plates between which the cord is required to pass,
and between which it is compressed with as much force as it is desirable to give the
requisite tension; the said tension, however, being elastic produced by a spring w
through which a stud from one of the said plates passes and is thereby pressed
with the power of the said spring against the opposite plate and the cord com-
pressed between them. To adjust the pressure of the said spring a screw nut is
placed upon the said stud, whereby the said spring may be more or less compressed
and its tension thereby varied. In order to prevent the accidental turning of the
said nut and the unintentional variation of the said pressure the lower end of the
nut is made square, and through the end of the spring is made a corresponding
square orifice, so that the pressure of the said spring upon the said square will
restrain and prevent the turning of the nut from any accidental cause. When it is
desired to vary the tension of the said spring it may readily be done by compressing
the same with the end until free from the square described, when the nut may be
turned either forward or backward, and may again be locked when the spring is
released.
Upon the end of the shaft T¹ there are two arms U₁ and Y", the former is fixed
upon the said rod, and the other is moveable but restrained and held in position by
a spring y which has its bearing upon a short arm z also fixed to the said rod; this
arm Y is the compressor against which the binding arm A¹ forces the sheaf while
the binding is being performed, and compresses the same without strain upon the
binding cord; and the springy is useful in making the said compression to a certain
degree elastic, so that there is no danger of breaking any of the parts, provided the
bundle be larger than desired. When the binding has been completed, the arms U¹
and Y are caused to rest by the turning of the rod T'in its bearings within

page_text: the tubular shaft K¹ so as to release the bundle which is therupon discharged by
the advance of the binding arm A¹.
Upon the shaft K¹ and represented in the Drawings as about midway thereof
there is a cam a¹, and the connecting rod E¹ which actuates the cut off mechanism
is forked and bent in the form of a hook at its outer end so as to partly surround
the said shaft and embrace the cam a', so that periodically during the revolution of
the said shaft K¹ the connecting rod E¹ is thrown forward, and the cut off is actuated
as hereinbefore described. Upon the outer face of the wheel N' there is a cam b¹
which is represented as a groove, though that form is not essential. Transversely
in front of the said wheel there is also a slight arm d, one end of which is sup-
ported and guided in the stationary box i adapted to the bracket J". The other
end of the said arm is provided with a large slot sufficient to embrace the pinion
V₁. Along one side of the said slot there is a series of gear teeth which mesh with
the teeth of the said pinions, so that the said arm as it is reciprocated backwards
and forwards imparts to the said pinion a vibratory rotation. A pin or stud
projecting from the side of the said bar & engages with the cam 61, so that as the
wheel N revolves the bar is caused to reciprocate backward and forward in the
bearings. The outline of cam b' is such that it imparts to the said bar d' an inter-
mittent reciprocation with intervening intervals of rest, and the pinion V has a
corresponding intermittent vibratory rotation with corresponding periods of rest,
and the compressors U₁ and Y are thereby hold rigidly in position while the
bundle is being bound, and are caused to recede at the proper time for the bundle
to be discharged.
The mechanism applied for the purpose of knotting the binding cord may be of
any approved description, and is located upon the sill D beneath the receptacle V
with its knotting devices projecting into the slot F', so that the binding cord is
properly carried thereto by the binding head. For this purpose devices which have
à vibratory rotation are preferred, but it is not designed to restrict this Invention
to devices of any particular character. Supposing however that a knotting device
having a vibratory rotation had to be employed, the shaft g' is placed in proper
bearings above the sill D, whereby the said knotting devices may be actuated and
the requisite vibratory reciprocation of the said shaft g¹ may be effected by a
vibratory rack in mesh with the pinion I upon the end of the shaft g¹. The
said rack is pivoted to the end frame A, or to a suitable bracket projecting there-
from, and is caused to reciprocate at the proper time by a cain k placed upon the
side of the wheel N₁, the said cam being similar in configuration to the cam b', but
adapted to the position of the arm from the vibrating rack which engages with the
said cam k².
As herein before stated it is desirable in discharging the bundle to discharge it
towards one side of the machine, so as to leave a clear path into which the driving
wheel may pass on the next round, and for this purpose attached to the rear sill D
is a horizontal projecting and curved horn or arm m³ which supports one end of the
bundle as it is discharged from the receptacle V and prevents it from falling upon
the ground, also attached to the machine at some convenient point is a curved arm
or horn n for the purpose of arresting and preventing the discharge of the bundle
at one end. This arm or horn may be conveniently attached to the bracket Ju
which is slotted for the purpose of making it adjustable, though it is not essential
that it should be attached to the said bracket. When, therefore, the binding arm
A¹ advances after the completion of the binding of the bundle to discharge the said
bundle from the machine, one end of the sheaf is arrested and held by the horn n¹
while the other end of the said bundle rests and slides upon the arm m³, and the
bundle is thereby caused to swing round and fall to the ground with its length in
the direction of the advance of the machine or thereabouts, and its position nearly
in line with that side of the machine which is towards the driving wheel. The
arios or horns m' and n¹ may be dispensed with, if for any reason it is not necessary
to deliver the sheaf towards one side of the machine as described.

page_text: The mechanism for making the knot and securing a band around the bundle
which it is preferred to use will now be described. The details of the same are
shown in Figures numbered from 9 to 26.
A is a rotary knotting hook. Its initial position is shown in perspective in
Figure 14. The end of the cord a being held by the gripper B2 extends therefrom
upward and rests in the bend of the hook A² and thence extends to the spool. The
cord carrying arm C² at the proper moment seizes the cord a and conveys it around
the bundle into the hook As and in contact with the grippers B³, so that the grain
is enclosed within a loop of the binding cord, two parts of which come together at
the hook and gripper. At this point the operation of the knotting device com-
mences. The two parts of the cord represented by the single cord a³ in Figure 13
occupy the bend of the hook at the moment when the movement of the acting
mechanism of the hook commences. The first movement of the said mechanism
thrusts forward the finger D² so as to enclose within the bend of the hook the cord
a². This position is shown in Figures 15 and 16. When so enclosed the rotation
of the hook A commences, and its second position is represented in Figures 17 and
18, wherein the reciprocating jaw E has been drawn back towards the bend of the
hook. The fourth position represented in Figures 19 and 20, when one revolution
of the hook has been completed, carrying the binding cord around the neck of the
hook. The reciprocating finger D2 has been withdrawn from the point of the hook
and rests on the end of the jaw E, so that that part of the cord which rests above
the finger D is permitted to slip within the point of the hook between it and the
jaw E. The further revolution of the hook shown in Figures 21 and 22 causes
the jaw E again to advance so as to positively seize that part of the cord which
is between it and the point of the hook holding the same firmly while the loop of
the cord which surrounds the neck of the hook is caused to slip off by the operation
of the mechanism. The final discharge of the knot from the knotting mechanism
is effected by the recession of the jaw E as represented in Figures 23 and 24.
The gripper B is a sliding bar having a notch or L shaped end be faced with a
blade of hardened steel so as to form at one end a cutter which severs the cord at
the proper moment by shearing against a similar cutter attached to the franic of
the apparatus. Below the cutting blade the gripper is somewhat enlarged and has
a roughened surface and acts in connection with a moveable counter having a
similar surface, the end of the cord being firmly gripped between the gripper and
the counter at the moment the cord is being severed. The movement of the gripper
B takes place about the time represented in the fifth position in Figures 21 and
22 when it is advanced as shown in Figure 22 so as to release the end of the cord
to receive the cord between the twister and head of the binding arm C³, so that
when the said gripper is retracted again the cord will be severed and the bundle
liberated and the new end firmly held as before.
These in general terms are the various movements which effect the knotting
of the cord. The mechanism whereby the said movements are produced will now
be described.
The hook A is placed at the end of a shaft F³ to which is imparted a vibrating
rotary movement, that is, it is caused to rotate for a time in one direction and then
rotate for an equal time in the opposite direction so as to bring it back to the
point of starting. The forward rotation spoken of produces the knot, and the
return rotation brings the book back into position to receive the cord for another
knot.
The vibratory rotation may be produced by any convenient and known mechanism
but such mechanism does not form any part of the Invention desired to be protected,
therefore it is not shown nor described. Means of application, however, is shown
in the pinion G³ which is attached at the rear end of the shaft Fº.
It is not,
however, proposed to limit the apparatus to this means of connecting the said shaft
with its prime mover.
A slot is made through the back of the hook A³ to receive the jaw E³, and along

page_text: the back of the shaft and connecting with the said slot, there is a groove within
which the shank d² of the jaw E³ is placed, and in which it may move backward
and forward. Near the end of the said shank there is a small stud f" projecting
outward radially to engage with a suitable cam whereby the shank and the jaw E
are moved at suitable times. Upon the opposite side of the shaft F there is a
similar groove for the shank of the finger D2, the end of which extends into an
L shaped notch in the sleeve H, whereby the said finger D2 may be moved back-
ward and forward at the proper times as hereinbefore stated. Upon the side of
the shaft F³ there is also a transverse notch I in which the latch g³ engages at the
proper time and offers a slight resistance to prevent the said shaft from revolving
and retains it in its initial position during its period of rest. Near the rear end of
the shaft there is a bevilled pinion J which takes its revolution from the pinion
G, and is used to actuate the cams which determine the movements of the finger
D and the gripper and cutter B². In gear with the said pinion J² is a gear ring
K, and within the said ring is a cam wheel L having upon its face a cam groove
, the outline of which is shown in Figure 11. The said cam wheel is mounted
upon a shaft P which passes downward through the frame plate M³ of the apparatus
and engages with the said gear ring K2 by means of a spring latch * and notch t²,
whereby the revolution of the ring K³ in one direction causes a corresponding
revolution of the cam L, but its revolution in the opposite direction leaves the
said cam at rest. Above the cam I there is a traveller N2, the upper edge of
which is concave and fitted to the clutch groove k on the sleeve H, and the bottom
of the said traveller is provided with the stud n which rests in the groove ³, and is
moved backwards and forwards longitudinally when the cain L is rotated. The
stud n may be provided with the ordinary friction roller as represented. The
revolution of the pinion J and the gear ring K* thereof causes the sleeve H2 to
traverse backwards and forwards on the shaft F2, at times determined by the
cuvature of the cam groove and thereby causes corresponding advances and
retreats, with intervals of rest, of the finger D2 as above set forth. As hereinbefore
described the first and second positions included merely a change of position of the
jaw, as shown in Figures 13 and 16. That movement of the finger D2 prior to the
commencement of the revolution of the shaft F is produced by means of a slot in
the pinion J, or as shown in the Drawings (Figure 10) of the sleeve connected
with the pinion J2 and the pinion G, and a pin O which is inserted in the shaft
F and placed within the slot whereby the first movement of the pinion G would
be a free rotation upon the shaft F throughout the limit of the slot because the
said shaft will not be actuated until the pin 0% traverses from one end of the said
slot to the other, but this rotary movement prior to the revolution of the shaft F
will be communicated through the gear ring K² to the cam L' and is just
sufficient to thrust the tinger D2 forward from its position in Figure 13 to its
position in Figure 15.
The stud feugages with a cami groove m³ which is made in the stationary block
permanently attached to the frame 1, so that the jaw E is caused to move only
during the revolution of the shaft F. As above stated the shaft P passes through
the frame plate M³ and on the lowest side thereof has mounted thereon a cam
wheel Q, having upon its inner face a heart shaped cam groove p³ the larger portion
whereof is concentric to the axis of the wheel Q. The shank of the gripper B²
moves in guides on the under side of the frame M, and at its rear end has a stud
b³ which rests in the cam groove p² and may be provided with the ordinary friction
roller. The gripper and cutter B² is reciprocated at the proper times by a revolution
of the said cam. On the outer edge of the cam wheel Q there is a notch 9 which
engages with the end of the spring latch r and the said cam wheel Q³ is thereby
prevented from backward rotation. The gripper and cutter B2 act in connection
with and in position to a counter R as hereinbefore stated. The counter R²
being placed within guides on the under side of the frame M2 as shown in Figure
12, and made elastic or yielding to accominodate the gripper to cords of different

page_text: diameters by means of a spring S which constantly presses the said counter
forward into engagement with the gripper, but as stated, it is enabled to yield
slightly to accommodate the varying diameter of cords.
A rotation of the shaft F may vary from one and a half to ono and three
quarter turns and back again to the point of starting.
Having thus described and ascertained the nature of the said Invention and in
what manner it is to be performed, it should be observed in conclusion that it is
not desired to claim the several parts of the apparatus and mechanism hercinbefore
described separately and apart from each other as constituting the said Invention,
but that what it is desired to claim are,-
First. The construction and arrangement of the main frame of the machine
and the combination therewith of the mechanism for altering and retaining the
position of the same, substantially as hereinbefore described and set forth.
