page_text: the needle B comes in contact with the rear end of the arm C rocking the said arr
so as to bring the upright G in contact with the trip plate F and the extension I
with the drop board E thereby forcing the trip plate F and drop board E into th
position they are shown in Figure 1. Instead of the arm C acting directly on th
needle it can be arranged to act upon an independent shaft connected to the trip
mechanism by which the needle shaft and parts connected therewith are put into
action. As this invention has nothing whatever to do with the construction of the
trip mechanism herein referred to it is not illustrated, nor is it necessary to enter
into a description of it, as every harvester binder is provided with trip mechanism
by which the needle shaft and parts connected therewith are put into action
During the period that the needle and its parts are moving as described the cord
is carried around the bundle and knotter. The parts of the mechanism for effecting
this purpose being as follows:-
M is a cam wheel fixed to the knotter shaft N, and revolving therewith. The
segment of the gear O formed on the cam wheel M engages with the spur pinion P
formed upon or fixed to the spindle of the bill hook Q.
R is an arm fixed to the spindle S which is suitably journalled in the knotter
frame T and has on it and opposite to the arm K an arm U the opposite end of
which arm is connected to the push-plate V. This push plate passes between the
frame of the knotter and the tension plate W, which is held in position by a
suitable spring X. On one side of the frame T opposite to that on which the
push plate V is placed, is a knife Y pivotted at d. (see Figure 7). A pin Z projects
from the plate V through a slot è made in the frame T. This pin fits into a
curved slot made in the knife Y. All the parts so connected together. are
arranged so that the movement of the arm R shall put each part in motion at the
time it is required to act. To effect this movement the arm R projects into a
cam groove made in the face of the cam wheel M (see Figure 7) which cam groove
is shaped so as to give the arm the necessary movement during the revolving of
the cam wheel M. On reference to Figure 9 it will be seen that the spring X
fits over a stud g which projects from the frame T and is provided with a nut h,
so that the pressure of the spring X against the tension plate W may be increased
or decreased at pleasure. When the needle first enters the knotter it lays the
cord in the position indicated in Figure 4 the bill hook having revolved and
grasped the cord. At this time the hook part of the plate V is behind the tension
plate W and the cord k is clear of the hook m formed on the back of the knife Y.
Before the needle has finished its forward stroke, the push plate V is drawn out in
the position it is shown in in Figure 5 the cord k being held taut at this time.
Owing to the position of the needle it will be drawn in position ready to receive
the hook n. Just before the needle commences to return, the push plate V begins
to move back again towards the tension plate. The hook n formed on the push
plate V catches the cork k and forces it between the tension plate W which acts
as a cord holder to fasten this end of the cord until the needle has returned from
its initial position with the cord to surround the sheaf. While the cord k is being
released by the withdrawal of the push plate from the cord holder the knife Y
which had fallen below the cord k commences to rise and catches the said cord in
the hook m formed on the back of the said knife raising the cord into the position
indicated in Figure 5 so that it is clear of the cutting edge of the knife as
indicated in Figure 5. The knot is by this time in a position to be pulled off the
bill hook the knife Y descending and cutting the single cord which has been
carried around the sheaf by the needle. It will thus be observed by this arrange-
ment only one cord has to be cut by the knife Y. It will be observed that the
tension plate W has a curved extension o against which the cord k is pressed by
the forward action of the push plate V raising the cord above and in the path of
the upward movement of the knife so that the hook m will assuredly come in
contact with and raise the cord. On reference to Figure 7 it will be observed that
a plate p is placed on the frame T. The knife Y passes between this plate p and
the frame T. This plate supports the cord k while it is being cut by the action of

Improvements in Sheaf Binders.
A communication from JOHN SMITH MERCER, of Alliston, in the County of
Simcoe, Province of Ontario, Canada.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of
Middlesex, M.I. Mech. E., and Chartered 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 :-
The object of the invention is to improve and simplify the mechanism by which
the sheaf is compressed and the cord tied upon it, and it consists, essentially, in the
construction and arrangement of the parts hereinafter explained.
Referring to the drawings filed with the Provisional Specification

:
Like letters of reference indicate corresponding parts in each figure.
A is the needle shaft to which the needle B is fixed in the usual way. C is an
arm loosely journalled on the needle shaft A. One end of this arm extends back
immediately below the needle B against which it butts, as indicated in Figure 1.
The other end of this arm extends forward and has an extension D, which forms a
support for the drop board E. The trip plate F, is hinged to the table at a and is
supported by the upright G, which extends from the arm C as shown.
His a curved plate connected to the frame of the binding table and extending
through a slot in the arm C.
When the grain is being packed into a sheaf it presses against the trip plate F

page_text: which plate, being hinged or pivoted as shown, is forced down pressing against the
upright G causing the arm C to rock on its pivot forcing the rear end of the said
arm against the needle B which is thereby raised until its shaft A is revolved
sufficiently to trip the mechanism by which the needle shaft and parts connected
therewith are put into action.
When the needle B is put into motion it moves away from the rear end of the
arm C, permitting the front end of the arm C to fall until the hooked end of its
bolt J comes in contact with the shoulder formed on the curved plate Has
indicated. As the needle B continues to revolve, its heel I comes in contact with
the bolt J which being supported by a spring K recedes down sufficiently to permit
the heel of the needle to pass. At this period, the needle compresses the sheaf and
puts the cord around it. When the needle commences to return to its initial
position, the heel I immediately comes in contact with the end of the bolt J pushing
the said bolt longitudinally so as to carry its hooked end clear of the shoulder
permitting the arm C to fall by its own gravity into the position indicated in
Figure 2 permitting the trip plate F and the drop board E, to fall clear of the
sheaf which is then immediately thrown off the machine by the action of the
discharge arms L. By the time that the sheaf is discharged the back of the needle B
comes in contact with the rear end of the arm C rocking the said arm so as to bring
the upright G in contact with the trip plate F and the extension D with the drop
board E thereby forcing the trip plate F and drop board E into the position they
are shown in Figure 1. Instead of the arm C acting directly on the needle it can
be arranged to act upon an independent shaft connected to the trip mechanism by
which the needle shaft and parts connected therewith are put into action. As this
invention has nothing whatever to do with the construction of the trip mechanism
herein referred to it is not illustrated, nor is it necessary to enter into a description
of it, as every harvester binder is provided with trip mechanism by which the
needle shaft and parts connected therewith are put into action. During the period
that the needle and its parts are moving as described the cord is carried around the
bundle and knotter. The parts of the mechanism for effecting this purpose being
as follows:-
M is a cam wheel fixed to the knotter shaft N, and revolving therewith. The
segment of the gear O formed on the cam wheel M engages with the spur pinion P
formed upon or fixed to the spindle of the bill hook Q.
R is an arm fixed to the spindle S which is suitably journalled in the knotter
frame T and has on it and opposite to the arm K and arm U the opposite end of
which arm is connected to the push-plate V. This push plate passes between the
frame of the knotter and the tension plate W, which is held in position by a
suitable spring X. On one side of the frame T opposite to that on which the push
plate V is placed, is a knife Y pivotted at d. (see Figure 7). A pin Z projects
from the plate V through a slot e made in the frame T. This pin fits into a curved
slot made in the knife Y. All the parts so connected together are arranged so
that the movement of the arm R shall put each part in motion at the time it is
required to act. To effect this movement the arm R projects into a cam groove
made in the face of the cam wheel M (see Figure 7) which cam groove is shaped
so as to give the arm the necessary movement during the revolving of the cam
wheel M. On reference to Figure 9 it will be seen that the spring X fits over a
stud g which projects from the frame T and is provided with a nut so that the
pressure of the spring X against the tension plate W may be increased or decreased
at pleasure. When the needle first enters the knotter it lays the cord k in the
position indicated in Figure 4 the bill hook having revolved and grasped the cord.
At this time the hook part of the plate V is behind the tension plate W and the
cord k is clear of the hook m formed on the back of the knife Y. Before the
needle has finished its forward stroke, the push plate V is drawn out in the position
it is shown in in Figure 5 the cord k being held taut at this time. Owing to the
position of the needle it will be drawn in position ready to receive the hook n.
Just before the needle commences to return, the push plate V begins to move back

page_text: again towards the tension plate. The hook n formed on the push plate V catches
the cord k and forces it between the tension plate W which acts as a cord holder to
fasten this end of the cord until the needle has returned from its initial position
with the cord to surround the sheaf. While the cord k is being released by the
withdrawal of the push plate from the cord holder the knife Y which had fallen
below the cord k commences to rise and catches the said cord in the hook m formed
on the back of the said knife raising the cord into the position indicated in
Figure 5 so that it is clear of the cutting edge of the knife as indicated in Figure 5.
The knot is by this time in a position to be pulled off the bill hook Q the knife Y
descending and cutting the single cord which has been carried around the sheaf by
the needle. It will thus be observed by this arrangement only one cord has to be
cut by the knife Y. It will be observed that the tension plate W has a curved
extension o against which the cord k is pressed by the forward action of the push
plate V raising the cord above and in the path of the upward movement of the
knife so that the hook m will assuredly come in contact with and raise the cord.
On reference to Figure 7 it will be observed that a plate p is placed on the frame T.
The knife Y passes between this plate p and the frame T. This plate supports the
cord while it is being cut by the action of the knife. It is also shaped, as
indicated to hold the cord while the jaws of the bill hook are open and revolving
to grasp the cord.
On reference to Figures 8 and 10 the improved formation of cord slot in the
breast plate will be understood. A half moon recess p is made on one side of the
cord slot r at a point where it is desired to hold the cord while the knot is being
effected. On the opposite side of the cord slot r a plate s is fixed having a hooked
end t which projects into the half moon recess q as shown. One point of the plate
forming the half moon recess 9 overlaps the plate s leaving just sufficient space
to permit the cord to enter the said recess; this point overlapping the plate s
prevents the cord escaping from the recess 9 and the shape of the half moon
recess forces the cord up the bill hook during its revolution. The hooked-shaped
point t of the plates holds the cord in position and prevents it slipping off the
bill hook before it begins to revolve. On reference to Figure 10 the bottom
side of the point is shown. A downward projection w is formed on the bottom
of the point which projection prevents the cord slipping off the point until the
bill hook has grasped the cord.
