The same part is designated by the same reference sign wherever it occurs in
the several views.
Reference sign A, designates the frame of the machine; B, the binder deck;
C, the knotter operating shaft; D, the main operating shaft; E, the needle; F, the
packer cranks; G, the packers. The main operating shaft D, is journaled in
suitable hangers H, depending from the frame, and mounted on said shaft in
close relation to the plane in which the needle operates is the main operating
gear J, adapted to actuate the several devices as hereinafter more fully explained.
In a suitable bracket or brace rod or arm K, is journaled the packer shaft L,
carrying or formed with the packer cranks F. This shaft L, is continuously
rotated when the machine is in operation in the usual manner of machines of this
class. An extension M, of the packer crank shaft is journaled in a brace rod or
arm N, of the machine frame, and upon this extension is loosely mounted a
sleeve O, having or carrying gear teeth P, thus forming a pinion, said pinion P,
being arranged to drive main gear J, as, for instance, through an intermediate
pinion Q, suitably journaled in the frame of the machine. A clutch dog R, is
pivotally mounted upon sleeve 0, and revolves therewith upon extension M, though
capable of independent rocking movement about its pivot relative to said sleeve.
This clutch dog is provided with an extension S, adapted, when said dog is suitably
rocked about its pivot, to be thrown into the path of travel of the rollers T, or
other suitable engaging device carried by the packer crank. A spring U, is
arranged to constantly exert its tension upon said dog in a direction to rock the
same about its pivot and into position for the roller or engaging device T, to
engage the extension S, of the clutch dog, whereby said sleeve 0, and pinion P,
are rotated, thus effecting the actuation of main drive gear J. Clutch dog R, has
formed thereon a lug V, which arranged to be engaged by a lug W, on the
back of the needle when the parts are brought into suitable position, thereby
causing dog R, to be rocked about its pivot against the action of spring U, and in
a direction to permit the rollers or engaging devices T, to clear the extension_S,
of the dog, thus arresting the rotation of sleeve 0, and pinion P, and hence also
arresting the actuation of main drive gear J.
When the lug or stop W, on the needle is in engagement with lug V, of the
clutch dog, that is, when the main drive gear J, is out of action, the needle E,
occupies its fully retracted position. This is the position of the parts when the
bundle is being formed. When a sufficient amount of grain to form a bundle
has been collected it is necessary to set in motion the mechanism by which the
bundle or gavel is compressed, tied and ejected. To do this it is necessary to
trip the clutch by which the driving gearing is held out of action. In the
present instance the arrangement is such that the needle itself forms the trip,
and the arrangement by which the desired result is accomplished will now be
described.
In the framework of the machine is mounted a shaft, stud or other suitable
support A, upon which the needle E, is sleeved to rock. Beyond this point of
pivotal support the needle is provided with an extension B'," which, when the
needle occupies its retracted position, with lug or stop W, thereon in engagement
with lug V, of dog R, extends above the binder deck and in the path of the
grain while being acted upon by the packers G. Therefore, when the pressure
of the grain upon this extension attains a certain degree, the needle is slightly

page_text: rocked thereby about its pivotal support, thus carrying lug or stop W, out of
engagement with lug V, and hence permitting spring U, to rock dog R, into
position for extension S, thereon to be engaged by a roller or engaging device T,
on the packer cranks, thus rotating sleeve 0), and pinion P, and main drive
gear J, through which the compressing, knot-tying and bundle-ejecting
mechanisms are actuated, as will presently be more fully explained. If desired,
and in order to vary the sizes of bundles, the needle extension B', may be supple-
mented by an arm C', suitably bolted as at D', Fig. 3, to a flange E¹, formed on
the needle, and the supplemental piece C, may be provided with a heel exten-
sion F, arranged to engage under flange E¹. (See dotted lines, Fig. 4). By
this construction the supplemental piece may be suitably held and adjusted so as
to regulate the point at which the needle effects a tripping of the clutch. In
Figs. 9 & 10 this supplemental piece C₁, is shown as pivoted to the needle, and a
set screw G¹, regulates its position relative to the extension B₁, thus regulating
to some extent the size of the bundles of grain formed by the machine.
Extension B, of the needle is slotted as at H', and through this slot is loosely
connected to said extension one end of a pitman J, the other end of the pitman
being pivotally connected to a wrist pin K¹, mounted upon the face of drive gear J.
From this construction it will be seen that when said gear J, is rotated the
needle E, is rocked about its support A', and thus advanced to its work. By the
provision of slot H', in extension B', the needle is permitted a slight movement
about its pivotal support A', independent of driving pitman or link J. This
slight independent movement enables the needle to serve as a trip for the clutch
mechanism which controls the actuation of main gear J. A spring L', is arranged
to exert its tension at one end upon link J, and at the other end against a
convenient part of needle extension B₁. This spring normally acts to hold the
needle yieldingly against rocking movement independent of its operating pitman J,
and hence the tension of said spring regulates the degree of pressure required
to rock the needle sufficiently to trip the clutch. The tension of this spring may
be regulated by adjusting screw M¹.

The relative arrangement of the connections of pitman J, to needle extension B¹,
and wrist pin K¹, on drive gear J, is such that the needle, after being rocked
independently of its power driving mechanism sufficiently to trip the clutch thus
setting in motion drive gear J, is advanced to its work from its normal position
of rest beneath the binder deck, during the rotation of gear J, through the first
quarter of its revolution. During this period the angle between a radial line
of said gear which includes said wrist pin K¹, and the line of pitman J¹, gradually
approaches a right angle. Thus the needle advances to its work rapidly. During
the second quarter of the revolution of gear J, the speed of advancement of the
needle gradually diminishes, while the power exerted in effecting its advancement
increases as the wrist pin K¹, passes its dead center," until the needle completes
its advance movement This point is indicated in dotted lines, Figs. & 7. At
this point the tying and knotting operations, presently to be described, are accom-
plished while the bundle is held under the maximum compression. Further
rotation of drive gear J, causes the needle to begin to recede, the receding move-
ment being slow at the beginning, by reason of the position of the wrist pin K.
This is advantageous for the reason that expansion of the compressed bundle is
gradual, thus drawing the knot in the binder cord tight, and hence resulting in
a compact well formed bundle. During the last quarter of the complete revolution
of gear J, the needle is rapidly retracted to its normal position of rest beneath
the binder deck and into position for the lug W, thereon to engage stop V, thus
disengaging the clutch mechanism and arresting the operation of gear J.
Co-operating with the packers G, in forming the grain into a bundle and with
the needle in effecting a compression of the formed bundle, is the compressor
hook N¹. This hook is carried by the compressor lever 01, suitably sleeved to
rock upon the support A', upon which the needle is pivoted. Also sleeved to rock
upon this support is the compressor bar P. This bar is provided with an arm Q',

page_text: depending therefrom, in position for the end thereof to be engaged by a mutilated
peripheral cam flange R¹, formed on the face of drive gear J. Mounted on a
rod S', carried by the compressor bar 1", is a spring T, said spring being inter-
posed between the compressor lever 01, at one end, and an adjustable nut U¹, at
the other end. From this construction it will be seen that the compressor hook N',
is supported by a yielding spring pressure, when said hook occupies its position
above the binder deck in co-operative relation with respect to the packers and
needle. In order to reduce friction, I provide an anti-friction roller V¹, in the
end of arm Q, as shown. Preferably the mutilated cam flange R¹, is of a length
somewhat less than a semi-circumference, and at its end is provided with a seat
or projection W, in or upon which the end of arm Q¹, rests when the compressor
hook is in position elevated above the binder deck. When gear J, is rotated the
cam flange R', engages the end of arm Q', and thereby raises the compressor lever
and hook, holding said hook elevated above the binder deck through the yielding
medium of spring T. This is the condition of the parts while the bundle is being
formed and tied. A lug A2, (see Figs. 4 & 5) on the framework engages the
compressor lever and limits its rocking movement. By the time the bundle-
forming and knot-tying operations are completed the main drive gear J, has
reached that point in its revolution where the end of arm Q¹, rides off the mutilated
cain flange R', thereby permitting the arm Q1, and with it the compressor lever
and hook, to drop back into their initial and normally inert positions beneath
the binder deek and out of the way of the bundle-ejecting mechanism.
In order to insure a tripping of the clutch by the independent rocking movement
of the needle, the compressor lever O', is provided with a finger or projection B2,
arranged to engage under the needle. Therefore, if, through any cause, the
pressure of the grain against the needle extension B', or its supplemental piece C
should fail to trip the clutch the pressure against the compressor hook will.
When the needle is in advanced position the incoming grain for the next succeed-
ing bundle collects behind it and continues to pile up until the needle is again
retracted below the binder deck. The pressure of this incoming grain against the
back of the needle tends to prevent the needle from being fully retracted beneath
the binder deck. In order to avoid this objection and to insure the retraction of
the needle to its fullest extent, a lug C2, is formed on the needle, and in position
to be engaged by pitman J, or else a roller D2, on wrist pin K¹, as the needle
nears its retracted position, thus positively forcing the needle home to its retracted
position beneath the binder deck.
In the operation of a grain binder embodying the invention, a pounding of the
parts results from the rollers F, of the packer cranks riding over the tail of clutch
dog R, thus causing undue wear and looseness, besides a disagreeable noise. In
order to avoid this objection the seat or shoulder W, is provided in the end of
mutiliated cam flange R¹, this seat or shoulder receiving the end of arm Q¹, and
hence locking the main drive gear against any tendency to reversely rotate.
In order to accommodate for any variations in the size or construction of parts,
a string E2, is arranged to bear against the cam flange R¹, said string operating
to overcome any back-lash therein.
In order to prevent stalks of grain from catching in the gears which drive the
main drive gear J, and also under the clutch dog, whereby the proper tripping
of the clutch is prevented, the train of gearing is preferably enclosed in a casing F2,
(see Figs. 4 & 5).
In the practical operation of a machine embodying the present invention, it is
important to impose on the twine with which the bundle is formed a certain
degree of tension during the action of the packers in forming and preliminarily
packing the bundle of grain, and it is desirable that this tension be comparatively
slight in order to prevent the packers, especially at the beginning of the operation,
from tilting the straws about the binding cord as a fulcrum, this being objection-
able because it thrashes out the grain, and also in the case of short grain disturbs
the symmetry of the bundle, whereas if only a slight tension is imposed upon the

page_text: binding cord, such cord yields gently to the pressure of the packers and still is
held with sufficient tautness around the forming bundle to prevent bulging of
the bundle while it is being formed. However, after the bundle has been formed
and the needle is advanced to its work of compressing the gavel and co-operating
in the tying of the knot, it is important to increase the tension on the cord in
order that such cord may be drawn tight around the bundle before the knot is
tied. To accomplish this result, the following arrangement is provided; (see
Figs. 3 & 4). The cord E, is threaded through an opening in a depending lug F2,
on a tension plate G2; thence the cord passes under said plate and between the
same and a rib or flange He, formed on the framework; thence on in any suitable
manner through a guide 2, and the eyes in the needle in the usual manner. A
desirable tension is imposed on plate G2, by means of a spring K², mounted on a
bolt L2, which is secured to said plate, the tension of spring K2, operating to clamp
plate G2, down upon the cord lying underneath it. A nut M2, serves to adjust
the tension of the spring. In order to increase this tension as the needle approaches
the limit of its compressing movement, a spring N2, is arranged to bear at one end
upon the upper surface of plate G2, and intermediate its ends said spring is coiled
around a suitable part of the frame, for instance, the journal bearing of the packer
shaft, and the inner end of said spring is arranged to be engaged by a cam sur-
face 02, on the hub of the needle. By this construction an increasing tension. is
imposed on the cord as the needle is advanced to its work, thus causing the cord to.
be drawn tight around the bundle before the knot is tied.
In Fig. 24 is shown a slightly modified arrangement of spring K2, for increasing
the tension upon the binder cord, and wherein, instead of coiling said spring about
a fixed part, a straight spring is employed, bearing at one end upon tension.
plate G2, and passing intermediate its ends through an eye in a lug P³, the inner
end of said spring arranged to be engaged by cam surface 02, in the manner above
described.
In order that tension plate G2, may be raised, should occasion therefor arise, said
plate is provided with a hook Q2.
It is desirable to operate the binder attachment of a harvesting machine by
hand, occasionally, and independent of the main driving means and of the other
parts of the machine, for the purpose of adjustment and the like. To accomplish.
this result, a sleeve R2, (see Fig. 1), is mounted to rotate with the packer shaft.
A shaft S2, is mounted in to rotate with this sleeve, and upon this shaft is mounted
the hand wheel T2. The packer shaft drive gear wheel U2, is mounted to rotate
freely upon said shaft S. Hand whcel T2, is provided with a drive dog V2.
spring W2, operates to hold said dog in position to engage a convenient part of
gear U2, and drive said gear when the hand wheel is rotated in one direction, but
which rides freely over or past said gear when the hand wheel is rotated in the
opposite direction, thus enabling the packer shaft to be independently rotated
when occasion arises.
A
From the foregoing description it will be seen that the gearing for actuating
the needle, including the clutch by which said gearing is thrown into and out of
action, is arranged in close proximity to the plane in which the needle operates,
instead of at the end of the binder deck as is usually the case in machines of
this class. Therefore, it is important to provide means whereby ready access
may be had to such gearing for the purposes of inspection, adjustment and repair,
and it is desirable that this access be had without the necessity of removing the
binder deck. To accomplish this result, an opening is provided in the binder
deck in proximity to the gearing, and a hinged trap door A3, is arranged to cover
such opening.
The knot-tying mechanism will now be described.
The shaft C, from which the knotter mechanism is operated is journaled in the
upper part of the frame A. This shaft may be a rotating shaft, as in Figs. 5 & 6,
or an oscillating or rocking shaft, as shown in Figs. 1, 2, 3, 4 & 17. In the case
of a rotating shaft, the rotations are imparted thereto by means of a pitman B³,

page_text: connected at the ends thereof to cranks C3, D3, respectively, carried by knotter
operating shaft C, and main drive shaft D, the main drive gear J, being mounted
on the latter for rotating the same. Carried by pitman B3, at about midway the
length thereof, are suitably spaced projections preferably in the form of anti-
friction rollers E3, and formed on or suitably secured to the binder frame are the
lugs 3, one at the top and the other at the bottom of the standard of the frame,
and spaced a distance apart corresponding approximately to the length of stroke
of the pitman. These lugs are V-shaped with their points presented towards each
other. From this construction it will be seen that when the pitman B³, reaches
either limit of its stroke, that is, when the crank arms C3, D3, are about in line
with each other, a lug F3, is received between the rollers or projections E3, thereby
serving as a fulcrum about which pitanan B³, may rock to assist the crank arms
in passing their dead centres. By this arrangement it follows that by every
complete rotation of the shaft D), that is, of main drive gear J, one complete revolu-
tion is imparted to the knotter shaft C, as shown in Figs. 5 & 6. In Figs. 1,
2, 3, 4 & 17, however, the arrangement is such that only a partial rotation is
imparted to the knotter operating shaft upon each rotation of main drive gear J.
That is, the knotter operating shaft is a rocking instead of a rotating shaft, but
the rocking motion is imparted thereto by a pitman B³, connected at its ends to
crank arms 03, and D³, respectively mounted on shafts C, and D. In this case,
however, since shaft C, only rocks, the projections E³, and lugs F³, may be
dispensed with.
In the case where the knotter operating shaft C, revolves, the discharge arm G³
is mounted thereon to rotate therewith, and its function is to discharge the bundle
from the machine after it is formed, compressed and tied.
The construction and operation of the knot-tying apparatus will now he
described, particular reference being had to Figs. 1, 2, 3, 17, 18, 19, 20, 21,
22 & 23.
The knotter operating wheel H³, in the form of a casting and having gear
teeth J³, on the face thereof, is mounted to rock with shaft C. Also supported
by the shaft C, is the knotter frame K³, and to which is secured the breast-plate L³,
in the usual manner. Suitably journaled in the knotter frame is the knotter
bill M³, carrying a drive pinion N³, arranged to be engaged and rotated
by the gear teeth J. Pinion N³, (see Fig. 21), is provided with a flat delay
surface 30, arranged to co-operate with a corresponding surface 31, on
the knotter wheel H³, to lock said pinion, and also the knotter bill, against
rotation except when the pinion N³, intermeshes with gear teeth J³. In order that
pinion N3, may be efficiently thrown into commission at the desired moment, a
pawl 32, is pivotally mounted on knotter wheel H³. A spring 33, is arranged to
normally but yieldingly hold one end of the pawl in position to engage a lug 34,
on the pinion.
The operation of this feature is as follows: When knotter wheel H³, is rocked
in one direction, namely, in a direction opposite to that indicated by the arrow
in Fig. 17, the pawl 32, rides over the lug 34, the spring 33, permitting the
engaging end of pawl 32, to be depressed sufficiently to pass over the lug, but
restoring such end to elevated position when the lug is cleared. Should, for any
reason, the spring fail to restore the engaging end of the pawl to elevated position,
a lug 35, (see dotted line, Fig. 17), is provided which engages the tail end of the
pawl and hence forces the engaging end of such pawl into elevated position ready
to engage lug 34, when the knotter wheel is rocked in the opposite direction. In
Fig. 17, the parts are shown in position at one limit of rocking movement of
knotter wheel H³, ready to rock in a direction to throw knotter bill pinion N³,
into commission. When such rocking motion occurs, in the direction indicated by
the arrow, the elevated end of pawl 32, engages the lug 34, and rotates the
pinion N³, into efficient engagement with the gear teeth J³.
Reference sign 78, designates the cord clamp suitably and adjustably mounted
on the knotter frame. Co-operating with the cord clamp to clamp the cord E³,

page_text: is the cord holder 80, carried by a shaft 79, suitably journaled in the knotter frame.
A gear 81, serves to actuate shaft 79. This gear is provided with two engaging
teeth 82, 83, arranged to be engaged respectively by the abrupt ends 84, and 85,
of the cam surface 86, of the knotter gear according to the direction in which the
knotter gear is rocked. Gear 81, is locked against rotation except when cam
surface 86, is passed by means of the projections 87, and 88, engaging said
cam surface. Thus, when wheel H³, is rocked in one direction the end 85, of
cam 86, engages tooth 83, and rocks the same, and with it the cord holder, and
when said wheel is rocked in the other direction end 84, engages tooth 82, thereby
rocking the cord clamp in the opposite direction. These rocking movements of
shaft 79, are suitably timed to effect the clamping of the binder cord at the
proper moments in the operation of tying, as will be explained hereinafter.
The cord-severing knife 89, is carried by cord holder 80, and has a cutting edge
curved in the direction of its length, as indicated in Fig. 17, thus securing
the advantage of a draw-cut. The curved back of the knife enables the knife when
returning to its initial position to readily ride under the cord. The cord clamp 78,
is provided with a crotch or opening 90, (see Fig. 23), into which the cord is laid
by the needle when the latter is advanced to its work, and on each side of this open-
ing said holder is provided with a clamping surface between which and the co-
operating cord holder 80, the cord is clamped. In Fig. 18, the cord holder 80,
is shown co-operating with one clamping surface of clamp 78, while in Figs. 19
and 20 the holder is shown co-operating with another portion or surface of the
clamp.
Pivotally mounted upon the breast-plate L³, at 92, is a stripper 91. A slot in
one end thereof is arranged to receive a projection 93, preferably in the form of a
roller, to reduce wear, secured to the cord holder. (See dotted lines, Figs. 19
& 20). This roller is eccentrically mounted with respect to the axis of rotation
of the cord holder. Therefore, when shaft 79, is rocked said roller, working in the
slot in the heel of stripper 91, effects a rocking of said stripper about its pivot.
The stripper is provided with horns or fingers 40, 94, on opposite sides of a slot
or opening 95, in which opening the cord is received. The function of the exten-
sions 94 and 40, is to maintain the cord in proper position to be operated on by the
knotter bill.
The operation of the knotter mechanism is as follows, reference being had to
Figs. 3 & 19: It will be seen that the end of the binder cord E, is held between
the surfaces of clamp 78, and holder S0. From thence the cord extends around
the flange of the holder and through the slot 90, Fig. 23, in the clamp, thence
over the knotter bill, over extension 40, of stripper 91, through the opening in
breast-plate L3, to and through the eye in the point of the needle, through guide J²,
underneath tension plate G2, and to ball in the twine holder in the usual manner.
This is the condition at the beginning of the operation of forming a bundle, as
seen in Fig. 3. Now the packers begin their operation of crowding the grain down
upon that portion of the cord lying between the point of the needle and the knotter
mechanism. This operation continues until the gavel is formed, whereupon the
pressure thereof against extensions B', or C¹, of the needle causes the needle to
rock about its pivot a sufficient distance for lug W, to clear stop V, of the drive
dog, whereupon rotation is imparted to main drive gear J, thereby rocking the
needle about its pivot and advancing it to its work, thus completing the loop of
the cord around the bundle, as indicated in Fig. 17. At the same time a rock-
ing movement is imparted to knotter shaft C, and hence to knotter operating
wheel H³, in the direction indicated by arrow, Fig. 3. During the entire extent
of rocking movement of the knotter operating wheel in this direction the knotter
bill-actuating pinion N3, will be locked against movement by reason of the engage-
ment of delay surface 30, thereof with the plane surface 31, of wheel H³, and also
by reason of the pawl 32, moving in a path such as to engage the edges of the two
extreme teeth of the pinion, as shown in Fig. 21. This movement of knotter
wheel H³, causes the end 85, of can surface S6, to engage tooth 83, of gear 81,
and thereby rock shaft 79, thus swinging holder 80, and with it knife 89, from the

page_text: positions occupied thereby as seen in Fig. 19, into the relative positions shown in
Fig. 18, the curved outline of the rear edge of the cutter causing the cord to ride
easily thereover. By reason of the engagement of roller 93, carried by holder 80,
in the slot in the tail of stripper 91, during the rocking movement of said holder
as above described, said stripper is also rocked about its pivot from the position
shown in Fig. 19, to the position shown in Fig. 18. This brings the stripper into
position for the cord to drop into the opening or crotch 95, in the stripper, as indi-
cated in Figs. 17 & 18, the cord still lying over the knotter bill, and the extreme
end of the cord instead of being folded around the flange of the cord holder, as
in Fig. 19, is simply held between the inner surface of clamp 78, which surface is
preferably scored or grooved as indicated at 39, Fig. 23, and the outer surface
of the flange on holder 80, as seen in Fig. 18. With the parts in these positions
the advancing movement of the needle is completed, thereby bringing the other
side of the loop of the cord around the bundle, up through the opening in breast-
plate L, and laying the same in the crotch 95, of the stripper, over the knotter
bill, through the opening 90, in the cord clamp. and between the flange of cord
holder 80, and the body of the knotter frame. While in this position the knotter
wheel H. which has previously attained the position indicated in Fig. 17, begins
to rotate in the direction indicated by the arrow in said figure. In the meantime
the engaging end of pawl 32, has been elevated into position to engage lug 34,
on pinion N³. Therefore, the rocking motion of gear H. will cause the end of the
pawl 32, to engage lug 34, and thereby turn said pinion into mesh with gear
teeth J, thus causing rotation to be imparted to the knotter bill, which effects
a tying of the knot in the usual manner well understood in the art. Before the
knotter bill completes its revolution, the end 84, of cam 86, engages tooth 82, on
pinion 81, and causes said pinion to begin its rocking movement in the opposite
direction to that above described, thus advancing knife 89, and the flange of the
cord holder across opening 90. This movement of the holder results in grasping
the end of the cord as delivered by the needle between the cord holder and the
clamp 78. also in releasing the original end of the cord, that is, the end shown
in Fig. 18. By this time the knotter bill has completed its revolution and has
formed the knot, and a continuation of the swinging movement of the knife severs
the clamped portion of the cord, as indicated in Fig. 20. The completion of the
swinging movement of the cord holder in this direction causes stripper 91. to draw
the knot tight and strip it from the knotter bill as shown in Fig. 20. When the
cycle of operations is completed the needle is again retracted to its initial position
beneath the binder deck, leaving the end of the cord clamped between clamp 78.
and the flange of holder 80, and folded around said flange as above explained
with reference to Figs. 3 & 19, ready for the formation of the next bundle.
The means for discharging the bundle after it is formed, compressed and tied,
will now be described.
In Fig. 6, wherein the knotter operating shaft C, revolves, the bundle is dis-
charged by means of suitable arms G5, mounted to rotate with said shaft. It is
desirable, however, to provide a construction wherein the least possible effort is
exerted and power expended during the discharge operation. This result cannot
be accomplished where the discharge arms are given an entire swing around the
axis of the knotter operating shaft. It has been endeavored to employ springs as
discharge arms, such springs mounted on a rocking shaft. This, however, is in-
efficient for the reason that the spring arms are advanced against the bundle before
the compressor hook begins to recede and hence before the bundle is ready to be
discharged, thereby storing up a tension in the spring arms representing the useless
expenditure of power. In the present instance the desired object is secured by
the following construction: Upon the end of shaft C, is mounted a sleeved
casting 57, and formed integrally with wheel H³, is a similar and co-operating
casting 58. Pivotally mounted, as at 60, in the outer end of each
of the castings 57, 58, are the discharge arms
proper 59. Pivotally
connected, as at 62,
to
each of the
arms
59,
is a rod G1, each

page_text: rod being arranged to pass through the chamber of the casting, and a spring 63,
is mounted on each rod and arranged to bear at one end against a collar 64, on
rod 61, and at the other end against the inner wall of the chamber of said casting.
The tension of the springs 63, is excrted in a direction to normally and yieldingly
maintain arms 59, in substantial alignment with the castings 57, 58, and radially
with respect to the axis about which shaft C, rocks, the end of the castings forming
stops for the arms. The heel of the arms 59, is also arranged when rocked about
their pivots to their fullest extent under the influence of springs 63, to engage the
rod 61, which thus forms an additional stop for the arms 59. And as above
explained, shaft C, is rocked instead of being rotated. The edges of arms 59,
presented towards the bundle when in position to discharge the bundle is shown
slightly curved in the direction of its length, as indicated in Fig. 17.
By the construction and arrangement above described the greatest amount of
leverage is secured during the discharge movement of the arms, while the said
arms are rigidly held during such movement by the abutment of the inner ends
thereof against the ends of castings 57, 58, and the rods 61, as above explained,
the curved edge conforming in a measure to the shape of the bundle, thus securing
a more efficient engagement with the bundle. The reverse movement of the arms
after the completion of the discharge movement is easily accomplished, and without
danger of carrying any portion of the straw forming the next succeeding gavel with
them, for the reason that when the arms in their reverse movement encounter the
gavel of the next succeeding bundle which is in process of formation, said arms yield
or fold back against the action of springs 63, and are thus enabled to pass freely
over the top of the gavel without interference. If for any reason the springs 63,
fail to return the arms 59, to their abutment with the ends of castings 57, 58, or
rods 61 when the limit of their reverse movement is reached, the following safety
provision is made. The ends of rods 61, are arranged to pass freely through the
rear or inner ends of castings 57, 58, and into position to engage suitable lugs 65,
formed on the framework. The engagement takes place as the discharge arms
approach the limit of their reverse movement, thus positively rocking the arms
by the endwise projection of rods 61. Thus the advantages of an increased lever-
age is: secured for the reason that crank arm C, by which knotter operating shaft C,
is rocked may be made longer than arm D³, by which reciprocation is imparted
to pitman B³, The curving of the discharge arms enables the arms to engage
the bundles without crowding them down upon the binder deck. In the construc-
tion above described, strippers: for the discharge arms are not required, and hence
the machine may operate closer to fences, trees or the like, without danger of
undue obstruction. At the same time, the discharge arms operate as stops to pre-
vent previously ejected bundles from rolling back into position to be caught by
the compressor hook when it is raised above the deck in case the bundle-carrier
should become overloaded.
The operation of the machine as a whole will be readily and fully understood
from the foregoing description.
Many variations in the details of construction and arrangement would readily
suggest themselves to skilful mechanics and still fall within the spirit of the
invention.
