I GEORGE FREDERICK REDFERN of the General Patent Office, No. 4 South Street,
Finsbury, in the county of Middlesex, Patent Agent do hereby declare the nature
of this invention to be as follows :—
This invention relates to improvements in grain binders in which the grain is
automatically bound as it comes from the harvester in a continuous stream as is
the case in the well known type of binders now in use wherein a tripping device,
a locking device and a packing device are employed; the object of this invention
is to provide an arrangement whereby the usual locking lever shall be securely
fastened at the conclusion of the binding operation, the locking lever at the time
of contact with the retaining dog being positively held in such contact until the hand
is placed around the sheaf thereby preventing the knotter from repeating or making
the second vibration incident to the rebound of the locking lever.
For this purpose the larger wheel when used in connection with the full train
of gearing meshes with an intermediate gear wheel into which a third wheel gears
whilst a driving pinion loosely mounted upon a continuously revolving shaft gears
with the latter wheel upon one side by which it is driven while the reverse side of the
said wheel meshes into and drives the intermediate wheel which in turn drives
the large gear-wheel. Or the pinion can be caused to gear with the gear wheel
having attached thereto a sprocket wheel which engages with a sprocket chain
by means of which the large wheel is driven thereby dispensing with the intermediate
gear wheel referred to. The improvement does not however relate to the manner
of operating the binding mechanism but consists in the method of securing the

page_text: locking arm; and the knotter repeating process is prevented by the use of the locking
dog, acting in conjunction with the locking arm in a manner substantially the same
in the several modifications in each of which the locking lever carries a supplemental
arm which in the arrangement of gear first herein before described rises diagonally
from the upper side and at the axial end thereof; the said arm when the mechanism
is locked abuts against a stud projecting from the face of the intermediate gear wheel
a crank arm is mounted upon a shaft and carries upon its free end a wrist pin by
which in conjunction with a connecting rod and wrist pin upon the face of the large
gear-wheel the said gear wheels and crank arm are united pivotwise for the purpose
hereinafter described.
i
Rising from the said arm is a rearwardly curved rod which passes through an ear
projecting laterally from the said arm and around which is coiled a spiral spring the
lower end of which rests upon the face of the ear, the other end abutting against
a nut mounted upon the free-end of the curved rod.
This spring is for the purpose of keeping the lever down to its work and retaining
it in a vertical line with the spring dog pivotally connected with the pinion ; a clutch
head engages with the heel end of the dog when the parts are unlocked by means
of which the operating wheels are set in motion for the purpose of binding the gavel.
The head is permanently secured to the pinion shaft and at all times revolves with it.
The said shaft also carries the packing fingers which are operated in the usual well
known manner.
In practical operation the grain is automatically packed in the binding receptacle
and when a sufficient quantity is gathered therein to work the trip, the locking lever
is (through the necessary mechanism) raised, which disengages it from the spring
dog, the heel of which immediately upon its release is caught by the revolving head
and by this means the train of gearing is set in motion and with it the entire binding
mechanism so that by the time the large gear wheel has made one entire revolution
the gavel has been bound and the shenf discharged from the machine. By this one
revolution of the large wheel the locking lever (by the connecting rod) is made to
rock backwards and to return so as to lock the driving mechanism until a succeeding
gavel shall be formed when the operation is repeated. In the above described type
of machine, when the locking lever is brought forwards and in position for locking
the binding mechanism by its engagement with the spring dog the movement is
rapid and as the dog during this descent is revolving with considerable speed the
concussion is so great that in striking the locking lever, it will cause the lever to
rebound so that the binding operation is repeated and by so doing a small bundle
is made or the discharged grain is scattered upon the ground in an unbound condition.
To obviate this objection an upright arm is placed upon the locking lever which armi
when the lever is in position to catch the revolving dog abuts against a stud placed
upon one of the gear wheels or against a swinging stud or a similar result can be
obtained by causing the upright arm to strike against a centrally pivotted stud the
upper end of which abuts against a crank pin or stud upon the large wheel.
This swinging stud is provided near its upper end with lugs the said stud being
connected pivotwise with another stud which forms part of a bracket; a spiral spring
is coiled round the latter stud one end of which is secured to the swinging stud while
the other end is so attached to the bracket as to allow of a spring adjustment of the
stud but the same is restricted in its throw by the lugs so placed upon the swinging
stud as to form a recess within which a stop pin enters after passing through the
fixed stud thus serving the double purpose of retaining the swinging_stud in its
lateral adjustment and limiting the vibratory movement of the same. In operation
the swinging stud (when the locking lever is brought down in position to form the
lock) immediately comes in contact (in a direct line) with the upright arm at the
same moment that the jaws of the locking lever and dog form a junction when
the free end of the swinging stud (upon the recoil of the spring dog) is advanced
by a pin so as to allow the usual tripping mechanism to operate for the purpose
of binding the succeeding gavel.

page_text: When sprocket wheels and a chain are employed instead of tooth gear wheels,
the gear wheels being caused to revolve a lock dog is by means of a diagonal arm
caused to come in contact with the tail pieces of the locking dog in such manner
that when the locking lever is brought into the right position to form the usual lock
the tail piece of the dog rests against the diagonal arm while the straight end of
the dog will abut against the wrist pin upon the underside thereof so as to effectively
prevent the rebound of the locking lover.
In each of the herein described modifications the same result is obtained, namely
the locking arm is held down in position until the full bundle is bound and discharged
by the same mechanical means thereby causing the locking dog to come in contact
with the arm of the locking lever thus preventing the repeating of the knotter.

page_text: I GEORGE FREDERICK REDFERN, of the General Patent Office, No. 4, South Street,
Finsbury, in the County of Middlesex, Patent Agent do hereby declare the nature
of this invention (A communication from abroad by Byron Eugene Huntley of
Brockport, State of New York, United States of America, Manufacturer) 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 improvements in grain binders in which the grain is
automatically bound as it comes from the harvester in a continuous stream as is the
case in the well known type of binders now in use wherein a tripping device, a
locking device and a packing device are employed; the object of this invention is to
provide an arrangement whereby the usual locking lever shall be securely fastened at
the conclusion of the binding operation, the locking lever at the time of contact
with the retaining dog being positively held in such contact until the band is placed
around the sheaf thereby preventing the knotter from repeating or making the second
vibration incident to the rebound of the locking lever.
In order to enable the invention to be fully understood I will describe how the
same can with advantage be carried into practical effect by reference to the
accompanying drawings in which figures 1, 2 and 4 are plan views of as much of
the gear-train of a binder as is neccessary to illustrate the invention, shewing the
locking lever in contact with the spring-locking pawl and the lock in operative
position the relative position of the parts when the locking lever is approaching the
locking pawl being indicated in dotted lines. Figures 3 and 5 are front elevations of
the gear-train shewn in figures 1, 2 and 4 and its immediately accessory parts.
Figures 6 and 7 are detached views of parts of the mechanism shewn in figures 4
and 5. Figure 8 is a plan view of locking mechanism similar to that shewn in
figures 1, 2 and 4, except that one of the intermediate gear-wheels is removed and
sprocket wheels and a chain which act as an operating motor are substituted therefor,
the view also illustrating the means of securing the locking lever upon machines thus
modified. Figures 9 and 10 are detached views drawn to a larger scale of the
supplemental locking dog shewn in figure 8. Similar letters refer to similar parts
throughout the several figures of the drawing.
For the purpose of this invention the larger wheel A when used in connection
with the full train of gearing (as shewn in figures 1 to 5) meshes with an intermediate
gear wheel A', into which a third wheel A³, gears whilst a driving pinion A³,
foosely mounted upon a continuously revolving shaft B, gears with the wheel A³,
upon one side by which it is driven while the reverse side of the wheel A², meshes
into and drives the intermediate wheel A', which in turn drives the large gear-
wheel A. Or (as shewn in figure 8) the pinion A³, can be caused to gear with the
gear wheel A³, having attached thereto a sprocket wheel which
a
with
engages
a

page_text: sprocket chain H, by means of which the large wheel A, is driven thereby dispensing
with the intermediate gear wheel A', hereinbefore referred to and shewn in figures i
to 5. The improvement does not however relate to the manner of operating the
binding mechanism but consists in the method of securing the locking arm; and the
knotter repeating process is prevented by the use of the locking dog, acting in
conjunction with the locking arm in a manner substantially the same in the several
modifications in each of which C is the locking lever; it carries a supplemental
arın C, which in the arrangement of gear shewn in figure 1 rises diagonally from
the upper side and at the axial end thereof; the said arm when the mechanism is
looked abuts against a stud c, projecting from the face of the intermediate gear
wheel A'; D is a crank arm mounted upon a shaft D'; it carries upon its free end a
wrist pin d, by which in conjunction with a connecting rod d', and wrist pin d³, upon
the face of the large gear wheel A, the said gear wheels and crank arm are united
pivotwise for the purpose hereinafter described.
Rising from the arm D, is a rearwardly curved rod e, which passes through an
ear c, projecting laterally from the locking lever C, and around which rod is coiled a
spiral spring e', the lower end of which rests upon the face of the ear c³, the other
end abutting against a nut e³, mounted upon the free end of the curved rod e.
This spring is for the purpose of keeping the lever C, down to its work and retaining
it in a vertical line with the spring dog F, pivotally connected with the pinion A³.
F¹, is a clutch-head engaging with the heel end of the dog F, when the parts are
unlocked and by means of which the operating wheels are set in motion for the
purpose of binding the gavel. The head F, is permanently secured to the shaft B
and at all times revolves with it. The shaft B, also carries the packing fingers.(not
shewn in the drawing) which are operated in the usual well known manner.
In practical operation the grain is automatically packed in the binding receptacle
and when a sufficient quantity is gathered therein to work the trip, the locking
lever C is (through the necessary mechanism) raised, which disengages it from the
spring dog F, the heel of which immediately upon its release is caught by the
revolving head F¹, and by this means the train of gearing is set in motion and with
it the entire binding mechanism so that by the time the wheel A, has made one entire
revolution the gavel has been bound and the sheaf discharged from the machine. By
this one revolution of the large wheel the locking lever (by the connecting rod d²)
is made to rock backwards and to return so as to lock the driving mechanism until a
succeeding gavel shall be formed when the operation is repeated. In the above
described type of machine, when the locking lever C, is brought forwards and in
position for locking the binding mechanism by its engagement with the spring dog F,
the movement is rapid and as the dog during this descent is revolving with
considerable speed the concussion is so great that in striking the locking lever C, it
will cause the lever to rebound so that the binding operation is repeated and by so
doing a small bundle is made or the discharged grain is scattered upon the ground
in an unbound condition. To obviate this objection the upright arm C¹, is placed
upon the locking lever C, which arm when the lever is in position to catch the
revolving dog abuts against a stud c, placed upon the gear wheel A¹, in the
arrangement shewn in figure 1, upon the wheel "A", in that shewn in figure 2, or
against a swinging stud 1 in the arrangement shewn in figure 4; or (as shown in
figure 8) a similar result can be obtained by causing the upright arm (", to strike
against a centrally pivotted stud or dog G, the upper end of which abuts against a
crank pin or stud d, upon the large wheel A.
I will now describe the construction and operation of the swinging stud I, shewn
in figure 4, this swinging stud I is provided near its upper end with lugs I¹, the said
stud being connected pivotwise with another stud i, which forms part of a bracket;
a spiral spring, is coiled round the stud i, one end of which spring is secured to
the swinging stud I, while the other end is so attached to the bracket, as to allow of
a spring adjustment of the stud but the same is restricted in its throw by the lugs I',
so placed upon the swinging stud I, as to form a recess within which a stop pin r,

page_text: enters after passing through the fixed stud i, thus serving the double purpose of
retaining the swinging stud in its lateral adjustment and limiting the vibratory
movement of the same. In operation the swinging stud I (when the locking lever Č
is brought down in position to form the lock) immediately comes in contact (in a
direct line) with the upright arm C¹, at the same moment that the jaws of the locking
lever C, and dog F, form a junction when the free end of the swinging stud I (upon
the recoil of the spring dog F) is advanced by a pin P, so as to allow the usual
tripping mechanism to operate for the purpose of binding the succeeding gravel.
When sprocket wheels and a chain are employed instead of toothed gear wheels (as
shewn in figure 8) the gear wheels being caused to revolve, the diagonal arm C³, will
be caused to come in contact with the tail piece of the locking dog G, in such a
manner that when the locking lever C, is brought into the right position to form the
usual lock the tail piece of the dog rests against the diagonal arin while the straight
end of the dog will abut against the wrist pin d, upon the underside thereof so as to
effectually prevent the rebound of the locking lever.
In each of the herein described modifications the same result is obtained namely
the locking arm or lever is held down in position until the full bundle is bound and
discharged by the same mechanical means thereby causing the locking dog to come in
contact with the arm of the locking lever thus preventing the repeating of the
knotter.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :-
:-
1. In a grain binder, operating automatically, the combination with the locking
lever having the supplemental uprising arm of a stop co-operating with the
supplemental arm whereby the locking mechanism is secured in the locked position
substantially as described.
2. In a grain binder operating automatically, the supplemental locking-dog
pivotted upon a stud secured to the frame-work of the binder between the operating
wheels, co-operating with the arm upon the locking lever and the stop & upon the
wheel A substantially as described.
3. In a grain binder operating automatically the combination with the locking-lever
having the supplemental uprising arm of the swinging stud I, having the operating
spring for bringing the same in a line with the supplemental arm, the parts co-
operating, substantially as described and for the purpose set forth.
4. In a grain binder operating automatically the combination of the locking-lever
having the uprising supplemental arm, the swinging stud I, the stud-operating spring,
the lugs I', and pin r, for limiting the throw of the stud substantially as described.
