IMPROVEMENTS IN
GRAIN BINDERS." A communication from abroad by Edwin Ruthven Whitney, of
Magog, in the County of Stanstead, in the Province of Quebec, Machinist, and
Thomas Conant, of Oshawa, in the County and Province of Ontario, Gentleman, all
in the Dominion of Canada.
This Invention relates to an attachment to harvesting machines in which the cut
grain is intermittently delivered from the table of the harvester to the platform of.
the binder, and from thence formed into a sheaf, tied, and pitched to the ground
automatically, and it consists,-
1. In an apron winding upon a cylinder intermittently delivering the straw to

for reloading.
2. The combination with an intermittently revolving apron cylinder of a rotating
cage or basket into which the rolled sheaf is delivered and bound by the winding
of a cord.
3. A rotating cage or basket having a hinged part intermittently and auto-
matically opening to receive the straw, and closing to press the same previous to
being wrapped by a cord.
4. The combination of the revolving cage as described of a cord-holding device
acting automatically at the loading and discharge of the sheaf.
5. The combination of a rotary needle, a thread catcher, and shears for looping,
holding, and severing the cord after winding on the sheaf.

page_text: 6. A spring lever and arm operating to close the hinged section of the cage at a
certain period of its revolution and compressing the straw therein during the
wrapping of the cord.
7. A stationary scoop having a yielding side spring in combination with a rotary
scoop or cage.
8. A delivery fork the shaft of which has a rotary swinging movement on a
fixed cam frame for discharging the bound sheaf from the scoop.

HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Patent Agents,
of 67, Strand, in the City of Westminster, Civil Engineer. "IMPROVEMENTS IN
GRAIN BINDERS." A communication from abroad by Edwin Ruthven Whitney, of
Magog, in the County of Stanstead, in the Province of Quebec, Machinist, and
Thomas Conant, of Oshawa, in the County and Province of Ontario, Gentlemen, all

This Invention relates to an attachment to harvesting machines in which the cut
grain is intermittently delivered from the table of the harvester to the platform of
the binder, and from thence formed into a shicaf, tied, and pitched to the ground
automatically, and it consists,-
1. In an apron winding upon a cylinder intermittently delivering the straw to a
revolving cage and a fixed table, and automatically unwinding from the cylinder
for reloading.
2. The combination with an intermitently revolving apron cylinder of a rotating
cage or basket into which the rolled sheaf is delivered and bound by the winding
of a cord.
3. A rotating cage or basket having a hinged part intermittently and auto-
matically opening to receive the straw, and closing to press the same previous to
being wrapped by a cord.
4. The combination of the revolving cage, as described, of a cord-holding device
acting automatically at the loading and discharge of the sheaf.
5. The combination of a rotary needle, a thread catcher, and shears for looping,
holding, and severing the cord after winding on the sheaf.
6. A spring lever and arm operating to close the hinged section of the cage at a
certain period of its revolution and compressing the straw therein during the
wrapping of the cord.
7. A stationary scoop having a yielding side spring in combination with a rotary
BCoop or cage.
8. A delivery fork the shaft of which has a rotary swinging movement on a fixed|
cam frame for discharging the bound sheaf from the scoop.
9. A discharging fork, as described, having spring prongs operated automatically
by a spring, cam bolt, and cam on the cam frame.
Fig. 1 is a perspective view of grain binder, and Fig. 2 is an elevation of the rear
side of the same.
A is a platform having a hinged connection to the table B of a harvester, and C is
a swivel by which the platform is attached to the harvester; D is an apron on
which the straw is delivered from the table of the harvester; the apron is inter-
mittently wound upon a cylinder E by means of a pinion a engaging with a cog
segment b on the main driving shaft c, and is unwound therefrom when the pinion

page_text: and cog segment are disengaged by the recoil of spring pulleys D, winding thereon
the cords e attached to the lower edge of the apron, and which apron is provided
with prongs f to retain the straw on the apron during the winding and casting the
load on to the scoop F and into a revolving cage or basket G having a spring sectional
part g which is closed in its revolution by the action of an arm H on a spring
lever I which is depressed by a rope or chain h winding on a pulley J which is
operated by a cog segment K on the main shaft; the closing of the part g presses
the contents of the basket ready for binding by the winding cord hereafter
described. The front part of the apron when unwound from its cylinder lies flat on
the platform A, the rear part lying at an angle corresponding to the angle of tho
side bars i, i, which is provided with a transverse rod j the ends of which work
against the under side of the bars i, i, which at the top are curved over the cylinder.
The action of the apron in winding causes the straw to be rolled into a bundlo
against the prongs fand is by them cast over into the basket and on to the table
to be bound. The hinged cover of tho basket when down is held closed by a
locking spring rack bars operated by a cam on the rear of disc k, which rack bar
has automatic releasing and engaging action with a projection on the cover of the
basket. L is the thread catcher, formed of a jaw closing on a bifurcated jaw to hold
the thread while the basket is revolving; these jaws are closed together by the
pressure of the contents of the basket on a lever which has the effect of operating
the jaws together to tightly hold the thread; when the contents of the basket are
removed the jaws relax their hold and the thread slides therein until the basket is
again loaded. M is a flanged pulley which guides the lock to open the basket, also
to open at the bottom the thread catcher; N is the thread catcher hinged at one
end to the platform, and is provided with a coil spring n to give tension to the
thread while being wound around the sheaf; O is the looper or needle which holds
the thread, and is so arranged to operate consecutively the hook and the holder Q
which is driven by the main wheel R, and is held by a spring and latch to keep
the needle in its place ready for use. P is a spool on which the binding thread is
wound for use. Fixed at S¹ to the shaft S to rotate therewith is a knife, which
when the looper comes down cuts the thread. T is the fork to throw the sheaf out
of the scoop.
The inner end of the fork is pivoted to a loose collar on the vertical
shaft p, which is driven from the main shaft by bevelled cog gears 9. The fork in
its swinging motion travels on a cam track which is provided with a cam t with
which a pivoted arm u on the shaft T of the fork comes in contact in performing
its gyration, and thereby draws down a spring bolt w which releases the prongs of
the fork to allow them to have a hinged movement on the shaft when casting the
sheaf from the machine. The main wheel R is provided with a segment flange 1
which engages with a curved arm 2 attached to the catch 3 to open the same to
allow the basket to revolve, also to hold it in its place while the parts of the
machine are working. The main wheel is also provided with segment cog racks 4, 5,
to engage with the spur cog wheel 6 on the shaft S to operate the needle, and
looper, and cather. The main wheel is also provided with a segment cam 8 to lift
a spring pawl of the holder Q out of engagement with a notched wheel on the
needle shaft, thereby allowing it to rotate sufficiently at the desired time to give
the required functional operation to the looper, which is operated by an arm 9
having a rack engaging with a cog pinion in the needle shaft. 10 is a break on the
main wheel engaging with shaft of the drum to ease its back when the apron is
unwinding therefrom; 11 is an arm pivoted at its rear end to a fixed projection
and is operated by a pin in the main shaft to raise the arm into contact with the
thread catcher L to close the same to secure the end of the twine before the basket
starts to revolve. Power will be transmitted to the binder by a cog pulley on
main shaft near the gearing for operating the fork, and another cog pulley on the
main shaft of the driving wheels of the harvester connected by an endless chain.
The scoop F is provided at one side with spring prongs 12 which give way to the
he af when being thrown from the scoop, and regain their vertical position when
the scoop is empty to hold the incoming load.
