page_text: I ALFRED JULIUS BOULT of 323 High Holborn London in the County of
Middlesex, England Civil Engineer do hereby declare the nature of said invention
for IMPROVEMENTS IN GRAIN BINDING MACHINES to be as follows:-
DESCRIPTION.
This Invention relates to those automatic binding machines in which the grain
to form a gavel is delivered by a packing mechanism against an opposing arm or
compressor, and also against devices which throw into action the binding mechanism.
The invention relates to improvements in the clutch mechanism for imparting
notion to the binder, to the trip mechanism for throwing the binder into and out
of action; to improvements in the construction of the tyer; to a throat plate of
peculiar construction co-operating with the tyer to effect the proper placing of the
cord to an automatic tension device, and to other features of secondary importance.
Certain of the improvements are applicable to binding-machines of various;
classes.
The machine is of the type in which the packers and the needle or cord-carrying
arm act upward through a binding table on which the grain is supported, and in
which the tying, cutting and clamping devices are located above a fixed breast-
plate which overlies the table and the grain passage.
The tyer frame A may be of any form adapted to sustain the other parts.
The stationary breast-plate C is suspended above the table by an overhanging.
arm or standard D.
At one end the shaft has two oppositely projecting cranks a, carrying packer
arms F, the heel ends of which are pivoted to swinging links G, which carry the
grain forward and compact it into a gavel against an upright compressor-arm, F,,
which projects through and above the table. The driving shaft E carries at its.
lower end a pinion H which communicates notion to a large gear wheel K, which
latter is provided with a wrist or crank pin carrying one end of a pitman L.
The opposite end of this pitman is connected to a crank arm M on a rock-
shaft N, lying horizontally boneath the binding table and provided at the opposite

page_text: end with a needle or cord-carrying arm O, which is vibrated by the rocking motion
of the shaft so as to rise through the table and carry the cord around the gavel to
the tying device.
I divide the packer-shaft transversely at any suitable point in its length and
unite its two portions by a clutch G G², the disconnection of which permits the
needle-operating devices to stand at rest while the packers continue in motion.
The clutch consists of two hubs secured to the ends of the shaft and toothed on
their adjacent faces.
One portion G¹ is cast upon or secured rigidly to that portion of the shaft which
bears the cranks, while another portion G³ is arranged to slide endwise on the
other portion of the shaft, which is made of a square form.
A spiral spring g applied around the rear portion of the shaft bears at one end
against one part of the clutch, and at the opposite end against a collar h of the
shaft and tends to hold the parts of the clutch normally in engagement.
In order to effect the automatic disengagement of the clutch at the completion
of the binding operation, I provide an arm T secured firmly on one end of a
horizontal rock-shaft S, the opposite end of which is provided with a trip-arm R,
extending through and above the binding table in position to be depressed by the
gavel acting thereon.
The arm G which can be moved in a vertical direction only bears at its extremity
a stud or roller i.
One part G² of the clutch is formed on the outside with a spiral groove or with
a spiral flange, terminating in a shoulder at one end.
The arm T has a heel projection c from which a rod U extends backward
through a stationary guide d to receive a spiral spring V, which is mounted in its
outer end and held under compression by an adjusting nut W.
The spring and rod tend to elevate the trip-arm and depress the arm R toward
the clutch.
The gavel bearing on the trip-arm R depresses its end and through the rock-
shaft elevates the arm T, out of engagement, thereby permitting the parts of the
latter to engage under the action of the spring g and transmit motion to the binding.
and tying devices.
The discharge of the bundle releases the trip-arm, permits it to rise and thereby
permits an arm to descend until its roller engages the spiral groove or flange of
the clutch.
The packer shaft is required to make a number of revolutions during the ascent
of the needle and the elevation of the tyer, and is required to continue its rotation
after the bundle is relieved from the compressor F, so that it no longer bears
forcibly on the trip-arm.
I provide the heel end of the needle-arm, on its shaft, with a cam surface,
arranged to act against a heel projection on a trip-arm.
The trip-arm being depressed by the gavel, is held in the depressed position
until the needle is elevated, the projection thereof holding the trip arm down until
bundle is discharged.
Passing now to the details of the binder-arm and cord-fastening devices, the
tying bill is located above the breast-plate and rotated intermittingly by teeth on
a large wheel carried on a horizontal shaft which is sustained as usual in the
overhanging bracket of the binder-frame, and provided with the driving gear
before referred to.
The tying bill consists of a spindle provided at one end with two jaws or bills
extending at substantially right angles to the axis, one jaw being rigid and the
other pivoted in order that they may grasp the cord between them and draw it
through the knot previously formed by winding the cord around the loop.
The pivoted jaw is extended at its heel end and provided with a roller to ride
against the stationary cam by which it is opened.
A cam or flange is formed on the face of the driving wheel to ride beneath the
end of the spring and lift the same for a short period of time.

page_text: In rear of the tying bill there is a revolving cord clamping disk having a notched
periphery, which enters at one side a stationary grooved plate or shoe whereby the
cord previously laid in position in one of the notches, is clamped tightly in place.
This clamping disk receives an intermitting rotation the thread being of such
shape as to give the disk the proper period of motion and intervening periods
of rest.
Between the tying bill and clamping wheel is a cord cutting knife of angular
form pivoted to the frame with its cutting edge extended between the tyer and
clamp in such position that the cord will be laid across is by the needle-arm while
its opposite end is extended in the rear of the wheel in position to be acted on by
an incline or clamp formed thereon.
This slot in the breast plate I make of a peculiar form.
The main portion lies in a vertical plane passing one end of the tyer so that the
point of the needle-arm may pass closely by the tyer spindle, but as the slot
approaches the tyer it is curved laterally thereunder and then continued backward
with an inclination in the opposite direction away from the tyer.
Nearly opposite the tyer spindle the slot is reduced in width to ensure the
guidance of the cord against the bills of the tyer.
Acting devices rotate the tyer so that its bills, or jaws extend forward obliquely
across the narrow portion of the slot.
As a result of the oblique position of the bills and of the lateral deflection of the
slot in advance thereof, the cord wheel being driven forward is directed toward
the tyer and caused to ride backward over its bills when the latter are rotated.
I cause it to stop before completing the rotation its bills at such time extending
backward instead of forward, so that the knot is permitted to pass off freely as the
bundle is delivered from the machine.

page_text: Improvements in Grain Binding Machines.
I, ALFRED JULIUS BOULT, of 323, High Holborn, London, in the County of
Middlesex, England, Patent Agent, 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 those automatic binding machines in which the grain
to form a gavel is delivered by a packing mechanism against an opposing arm
or compressor, and also against devices which throw into action the binding
mechanism.
The invention relates to improvements in the clutch mechanism for imparting
motion to the binder to the trip mechanism for throwing the binder into and
out of action; to improvements in the construction of the tyer; to a throat-plate
of peculiar construction cooperating with the tyor to effect the proper placing
of the cord; to an automatic tension device and to other features of secondary
importance.
Certain of the improvements are applicable to binding machines of various
classes but in the drawings I have shown a machine of the form which I consider
most advantageous. The machine shown is of the type in which the packers and
the needle or cord-carrying arm act upward through a binding table on which the
grain is supported, and in which the tying, cutting and clamping devices are
located above a fixed breast-plate which overlies the table and the grain passage.

Figs. 19 and 20 are perspective views of said parts separated from each other.
Figs. 21 and 22 are respectively a side view and a cross section showing the
means for relieving tho tyer bill from the action of its closing spring.
In the drawings, A, represents the tyer frame which may be of any form adapted
to sustain the other parts; B, the table on which the grain is delivered and bound;
C, the stationary breast-plate suspended above the table by an overhanging arm or
standard, D, usual in machines of this type.
Beneath the binding table I mount in bearings in the frame the horizontal
shaft, E, from which all parts of the binding mechanism are driven, the shaft
receiving constant motion from any suitable part of the harvester. At one end
the shaft has two oppositely projecting cranks, a, carrying packer arms, F, the heel
ends of which are pivoted as usual to swinging links, G, so that the points of the
packers rise through the table alternately with a circulatory action to carry the
grain forward and compact it into a gavel against the upright compressor arm, F¹,
which projects through and above the table as usual. The driving shaft, E,
commonly known as the "packer-shaft" carries at its lower end the pinion, H,
which communicates motion as seen in Fig. 5 through intermediate gear wheels, I,
and, J, to the large gear wheel, K, which latter is provided with a wrist or crank
pin carrying one end of pitman, L, The opposite end of this pitman is connected
to a crank arm, M, on the rock-shaft, N, lying horizontally beneath the binding
table and provided at the opposite end with the needle or cord-carrying arm, O,
which is vibrated by the rocking motion of the shaft so as to rise through the
table and carry the cord around the gavel to the tying device in a manner familiar
to persons skilled in the art. It will be observed that the packer shaft transmits
motion directly to the packers but indirectly to the needle arm.
In operating the machine the binder-arm must remain in a depressed position
during the accumulation of the gavel and until the latter has acquired a pre-
determined size.
To accomplish this end by disconnecting the needle driving portion of the shaft
from the cranked packer-carrying portion, I divide the packer-shaft transversely
at any suitable point in its length and unite its two portions by a clutch, G¹, G²,
the disconnection of which permits the needle operating devices to stand at rest
while the packers continue in motion.
The clutch consists as shown of two hubs secured to the ends of the shaft and
toothed on their adjacent faces. One portion, G¹, is cast upon or secured rigidly to
that portion of the shaft which bears the cranks, while the portion, G2, is arranged
to slide endwise on the other portion of the shaft which is made of a square form
as shown or provided with a spline to prevent the rotation of the part, G³, thereon.
A spiral spring, g, applied around the rear portion of the shaft bears at one end
against the part, G³, of the clutch and at opposite end against a collar, h, of the
shaft and tends to hold the parts of the clutch normally in engagement.
In order to effect the automatic disengagement of the clutch at the completion
of the binding operation, I provide an arm, T, secured firmly on one end of a
horizontal rock shaft, S, the opposite end of which is provided with a trip aim, R,
extending through and above the binding table in position to be depressed' by the.
gavel acting thereon.

page_text: The arm, G, which can be moved in a vertical direction only bears at its extremity
a stud or roller, 2. The part, G, of the clutch is formed on the outside with a spiral
groove or with a spiral flange, J¹, terminating in a shoulder at one end.
The arm, T, has a heel projection, c, from which, a rod, U, extends backward
through a stationary guide, d, to receive a spiral spring, V, which is mounted in its
outer end and held under compression by an adjusting nut, W. The spring and
rod tend to elevate the trip-arm and depress the arm R, toward the clutch. The
gavel bearing on the trip-arm, R, depresses its end and through the rock-shaft
elevates the arm, T, out of engagement thereby permitting the parts of the.latter
to engage under the action of the spring, g, and transmit motion to the binding and
tying devices. This action continues during the presence of the gavel above the
arm, R. The discharge of the bundle releases the trip-arm, R, permits it to rise and
thereby permits the arm, T, to descend until its roller, i, engages the spiral groove
or flange of the clutch. In consequence of this engagement the arm, T, being fixed
against lateral movement, the part, G2, of the clutch is caused to move endwise on
its shaft out of engagement with the part, G', thereby stopping the motion of the
needle and tyer.
The packer shaft is required to make a number of revolutions during the ascent
of the needle and the elevation of the tyer and is required to continue its rotation
after the bundle is relieved from the compressor, F, so that it no longer bears
forcibly on the trip-arm. In consequence of this action it is necessary to provide
mechanical means for holding the arm, T, positively out of engagement with the
clutch. For this purpose I provide the heel end of the needle arm on its shaft with
a cam surface, c, arranged to act against the heel projection, f, on the trip arm, R,
as plainly represented in Figs. 1 and 8. The trip-arm being depressed by the
gavel, is held in the depressed position thereby until the needle is partially elevated,
whereupon the projection, e, encountering the trip-arm holds the same down in a
positive manner until the bundle has been discharged.
In this manner the danger of the arm, R; unlocking the clutch at an improper
time is avoided.
Referring next to the compressor arm, F, against which the gavel is compacted
it is made of an angular or L-shape, and pivoted, as shown in Fig. 8 to the upper
end of a link, k, arranged to swing about a rock shaft bearing a crank, m, which is
connected by a link, n, to the heel of the compressor so that when the shaft is
rocked in one direction it will have the effect of throwing the compressor upward
and through the table in position to support the gavel while a rocking motion in
the opposite direction will have the effect of tipping the compressor downward
to the position shown in Fig. 8 in order that the bundle may be discharged over it.
The foot of the compressor is connected at its forward end by a link, o, to a heel
projection on the needle shaft so that as the needle rises to carry the cord around
the gavel the link is caused to draw the compressor bodily forward toward the
needle, thereby compressing the gavel between the needle and the compressor.
Heretofore it has been customary to pivot the compressor for this purpose directly
to the heel end of the needle the result of which was that before the completion
of the action the compressor was tipped downward and backward in such manner
as to receive a part of the grain at the top and cause an undue strain on the
binding cord. By this improvement this trouble is avoided as the compressor is
drawn and held squarely across the grain.
For the purpose of giving to the compressor F, a yielding or spring support
during its action on the gavel, I provide instead of the customary spring con-
nections the arrangement represented in Fig. 5. The rock shaft, l, to which the
heel of the packer is connected by the link, n, as before explained, is provided on
its outer end with a crank arm, ql, the end of which is pivoted to an arm, l, which
is in turn jointed to an arm, 81, jointed at its upper extremity to an angular
lever, t¹, pivoted to the main frame and actuated by means of a stud on its side
engaging in a cam groove, u¹, in the main gear wheel before referred to.

page_text: The two parts, i¹, and, s¹, constitute jointly a toggle lever. They are provided at
their adjacent ends with lateral arms or extensions, w, and w³, through which
there is extended a spindle, x', bearing on one end a spiral spring, y¹, and a com-
pressor nut, z¹. These parts tend to hold the two parts of the lever out of line with
each other or in other words in a bent condition.
While in this bent condition the lever through intermediate connections serves.
to sustain the compressor in its normal operative position. When, however, the
compressor is subjected to excessive strain by the accumulating gavel, the spring, y',
will yield and permit the toggle lever to straighten and elongate the effect of which
is to permit the rock shaft, l, to turn in the direction indicated by the arrow in
Fig. 5, thereby permitting the compressor to tip backward to a limited extent.
By turning the nut, ¹, the tension of the spring may be varied so that the
compressor will offer more or less resistance.
The lever, r, s, is moved bodily upward and downward by the cam wheel, and
lever, t, to lower the compressor below the table when the bundle is to be dis-
charged and to raise it thereafter to the normal position. The jointed lever and
spring constitute an improved yielding connection between the cam wheel and
packer shaft to take the place of the complicated devices now employed.
Passing now to the details of the binder arm and cord-fastening devices, X, is
the tying bill located above the breast-plate and rotated intermittingly by teeth
on the large wheel, Y, carried on the horizontal shaft, Z, which is sustained as usual.
in the overhanging bracket or standard of the binder frame and provided with the
driving gear, K, before referred to. The tying bill as shown in Figs. 14 and 15,
consists of a spindle provided at one end with two jaws or bills extending at
substantially right angles to the axis, one jaw being rigid and the other pivoted
in order that they may grasp the cord between them and draw it through the knot
previously formed by winding the cord around the loop. The pivoted jaw, q, is
extended at its heel and provided with a roller to ride against the stationary
cam, 82, by which it is opened. It is closed by the sliding rod, r, lying in a groove
in the spindle, and acted on by a stationary spring, 8, these features constituting no.
part of this invention.
The closing pressure applied to the pivoted jaw causes, in machines of the usual
construction an excessive friction and wear upon the roller of the bill and upon
the operating cam. I avoid this trouble by relieving the bill automatically during.
a part of the revolution of the tyer.
The most simple means for the purpose is a cam or flange, a³, formed on the face
of the driving wheel, Y, as in Figs. 21 and 22, to ride beneath the end of the
spring, s, and lift the same for a short period of time. In rear of the tying bill
there is a revolving cord clamping disk, t, having a notched periphery which enters
at one side a stationary grooved plate or shoe, u, whereby the cord previously laid
in position in one of the notches is clamped tightly in place. This clamping disk
receives an intermitting rotation from a thread or rib, w, formed on the periphery
of the wheel, Y, the thread being of such shape as to give the disk the proper
period of motion and intervening periods of rest.
Between the tying bill and clamping wheel is a cord-cutting knife, x, of angular
form pivoted to the frame, Z', with its cutting edge extended between the tyer and
clamp in such position that the cord will be laid across it by the needle arm while
its opposite end is extended in the rear of the wheel, Y, in position to be acted on
by an incline or clamp, z, formed thereon. The wheel, Y, makes one revolution
during the binding of each bundle and in so doing the cam, z, acting at the proper
time on the knife arm, x, causes the blade to rise against the overlying cord and
sever the same in the rear of the tyer thereby disconnecting the applied band from
the remaining portion of the cord, leaving the bill or spool end confined in the
clamp. A flat spring, h, secured to the breast plate at one end bears at its opposite.
end on the knife as in Figs. 9 and 10, to throw its edge downward after the action
of the cam, z,

page_text: The breast plate has the usual slot through which the point of the needle
ascends to present the end of the cord over the tying bill to the clamping wheel
or disk.
This slot I make of a peculiar form represented in Figs. 11 and 21. The main
portion lies in a vertical plane passing one end of the tyer so that the point of the
needle arm may pass closely by the tyer spindle, but as the slot approaches tho
tyer it is curved laterally thereunder as shown at, b', and then continued backward
with an inclination in the opposite direction away from the tyer as shown at, e¹.
Nearly opposite the tyer spindle slightly in advance thereof, the slot is reduced
in width to ensure the guidance of the cord against the bills of the tyer. It is
preferred to effect the reduction in width by securing on top of the breast-plate
a small plate, d, having a pointed end extended over the slot as in Fig. 11 and a
beveled or rounded edge to prevent the chafing or breaking of the cord which
would be likely to occur were it drawn over a thin or sharp edge.
Acting devices presently to be described rotate the tyer to the position shown in
Fig. 11 so that its bills or jaws extend forward obliquely across the narrow portion
of the slot with their ends overlying the edge of the plate, d².
The tyer remains in this position during the presentation of the cord. As a
result of the oblique position of the bills and of the lateral deflection of the slot in
advance thereof the cord-wheel being driven forward is directed toward the tyer
and caused to ride backward over its bills when the latter are rotated. This is an
important feature in that it prevents the possibility of the cord escaping over the
ends of the bill during the twisting operation and because it avoids the necessity
for using cord placing devices hitherto required in machines of this type. The
tyer, like others of this class, makes one complete revolution to form the knot.
Instead of being turned as usual with a continuous motion to its original position,
I cause it to stop before completing the rotation in the position shown by dotted
lines in Fig. 11, its bills at such time extending backward instead of forward so
that the knot is permitted to pass off easily as the bundle is delivered from the
machine.
During the discharge of the bundle the cord passing thence upward through the.
slot to the tying bills is drawn against the rear inclined edge, c¹, of the slot, which
assists in urging the cord toward the end of the bills, the slot being thus rendered
available as a stripper to assist in removing the knot from the tyer.
After the knot is delivered the tyer continues its rotation and assumes its
original position indicated by full lines in Fig. 11.
The means for stopping the tyer in different positions or at different points in
its rotation is shown in Figs. 9, 12, 13, and 16. The tyer spindle carries a
mutilated pinion, e, having teeth on one side only, and having on the opposite side
a flat delay surface, 1, and a shoulder, n¹. The driving wheel, Y, is provided with
teeth, n, to impart a. partial rotation of the pinion also with an annular delay
surface, o', to cooperate with the surface, l, of the pinion to prevent the rotation of
the tyer, and also with an annular delay surface, p¹, to encounter the shoulder of
the cam and prevent the tyer from being turned too far ahead.
It will be seen that the delay surfaces, o¹, and, p', extend but partly around the
wheel and that the gear teeth are located at an intermediate point.
The tyer stands normally in the position shown in Fig. 11, being held by the
action of the delay surface, o¹, against the corresponding surface of the pinion. As
the driving wheel revolves, the delay surface, o¹, leaves the pinion and the teeth, n¹
engaging therewith impart to the tyer about two-thirds of a revolution causing its
bills to twist the ends of the cord together into the form of a loop thereon, and
grasp the ends preparatory to drawing the same through the loop. When the tyer
reaches the position shown by dotted lines in Fig. 11, with the bills extended in a
rearward direction the teeth of the pinion leave the wheel and the motion of the
tyer ceases, its further rotation being prevented by the strain of the cord passing
thence to the sheaf,

page_text: The bundle is ejected in the usual manner sweeping the completed knot from the
tyer, after which the delay surface of the wheel acts against the delay surface of
the pinion completing the rotation of the latter so that it assumes its original
position preparatory to the application of the band to the next bundle.
The backward rotation of the knotter between the time of the action of the teeth
and the action of the delay surface is prevented by the roller on the heel of the
tyer bearing with a spring pressure against the abrupt shoulder of the opening cam
before alluded to. As regards the tyer the essence of the invention consists in
giving the same a partial rotation at a time, and causing its bill to be presented in
à forward direction to receive the cord and in a backward direction to release
the knot. The skilled mechanic will understand that the details of the driving
mechanism may be variously constructed to this end.
.
To ensure the passage of the cord through the opposite portion of the slot in the
breast plate and against the tying bill, a yielding tucker arm, g, is attached to the
needle on its inner edge near its point to ride against the underside of the breast
plate. This tucker may be variously formed but it is preferably made as shown
by bending an elastic wire into a U form the wire thus bent being fixed astride of
the needle and secured thereto as plainly represented in Figs. 3 and 10. The
forward end of the tucker is of a width greater than the slot in the breast-plate.
While the needle is depressed the tucker lies closely against its under face and
is inactive but as the needle ascends the end of the tucker rides against the under
face of the breast-plate and being held downward thereby it forces the cord before
into or beyond the tyer as in Figs. 10 and 21. The bound bundle may be
discharged by any suitable means but I recommend the use of the ordinary
revolving arm, 2. To automatically increase and diminish the tension of the cord.
I provide the devices shown in Figs. 17 to 20, consisting of a fixed casting having
two arms, b, through which the cord passes and of a rock shaft, c², having a long,
arm, d², and a short arm, e², both of which are perforated to permit the passage of.
the cord through them. The rock shaft is mounted in a casting so that its arms,
may swing to and fro past the fixed arms or guides, and the entire device is applied
to the machine in such position that the point of the needle will pass the same and.
extend the cord therefrom first in one direction and then in the other.
The cord being extended through the four arms and carried to and fro by the
needle, will by straining on the long arm, d², cause it and its companion c², to
assume such changing relations to the fixed arms that the cord will be compelled to
assume a bent or irregular course and then be permitted to straighten again.
The result is an automatic increase in the tension of the cord while the band is
being laid around the bundle and subsequently a decrease in tension. While I have
represented in the drawings the preferred form and arrangement of the parts it is
to be understood that the details may be modified in various respects without
changing the mode of action. Among other modifications of this character would.
be the formation of the cam, e, independently of the needle instead of integral
therewith and the attachment of the link, o, to an arm or projection on the needle
shaft instead of attaching it directly to the needle.
OPERATION.
The bundle having been bound and discharged the parts assume the position
represented in Figs. 2, 3, 5, and 6, the arm, T, holding the clutch, G, G¹, disconnected
so that the binding devices remain at rest while the packers continue in action.
The grain delivered from the harvester upon the upper edge of the binding table in
a continuous stream as usual, is carried downward by the packers beneath the
breast-plate and accumulated and compacted into a gavel against the compressor, F,
on top of the trip-arm, T. When the gavel attains the proper size it acts with

page_text: caused to operate the binding mechanism.
The cord held at one end in the
clamping wheel extends thence over the tyer bill and through the slot in the
breast-plate beneath the gavel to the eye of the needle and thence through
the tension device to the ball, spool or other source of supply.
The needle ascends and carries the cord over the gavel upward through the
breast-plate and backward across the tying bill in front of the advancing tucker, g',
to the clamping wheel.
During this action the inclined edge, b³, of the slot and the end of the tucker
cooperate to force the strands of cord backward over and across the tying bill,
which is at this time extended forward across the slot as in Fig. 11.
As soon as the cord is in position the tyer makes a partial revolution looping the
cord and grasping its ends and then stopping in the position shown by dotted lines
in Fig. 1, with its points towards the rear. The knife then severs the band, the
compressor arm, F, falls below the table and the ejector discharges the bundle, after
which the tyer continuing its rotation assumes its original position. During the
above action the cam, e, at the heel of the needle acts to hold the trip-arm, R, down,
and thus prevents the arm, T, from disengaging the binder clutch but as the needle
retreats at or about the time the bundle is delivered it releases the trip-arm so that
the clutch may be thrown out of action. The compressor having been in the
meantime elevated by the motion of the rock-shaft, l, the binding mechanism stops
and the formation of the next gavel begins.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent I declare that what I claim is:
1. In an automatic grain binder, the binder-driving shaft. E, and its actuating
clutch provided with an inclined or spiral surface, in combination with the rock-
shaft, S, mounted in fixed bearings and the trip-arm, R, and clutch driving
