Improvements in Harvesters.
A communication from THE MASSEY-HARRIS COMPANY, LIMITED, of Toronto,
County of York, Province of Ontario, Canada.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., 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 balance the binder as nearly as possible and to
simplify the driving mechanism thereof, and it consists, essentially, of removing the
gearing from the front of the machine to a point at or near its centre and arranging
the said gearing in a simple and compact form, substantially as hereinafter more
particularly explained.
Figure 1, is a perspective skeleton view of the mechanism arranged in connection
with this invention.
Figure 2, is a detail of the supporting bracket and gearing supported thereby.
In the drawing, A, represents a bracket rigidly fastened to the frame of the
machine and projecting sufficiently far to form a support for the driving gear, as
indicated.
B, is a bail rigidly fastened at one end to the frame of the machine and at its
other end to the bracket A, the bail and the bracket forming a rectangular enclosure
within which the needle operates and the driving gear is enclosed.
C, is packer shaft with the packer cranks D, and F, formed on it. This packer
shaft is suitably supported by the bracket A, and bail B, and operates in the
usual way.
The driver E and packer crank F, are made in one piéce and the
roller studs G, of the driver E, are rivetted or otherwise securely fastened on
the crank F.
The spur wheel I, is loosely journaled on the stud J, which projects from the
packer crank F. The dog K, is pivoted at a, to the spur wheel I, in the usual way.
L is a stop arm fixed to the spindle M, which is suitably journaled and has fixed
to its other end an arın N, on the end of which a roller O, is journaled. A trip
lever P is pivoted on the spindle M, and is provided with a pinching screw Q,
which projects through a slot b, in the arm N, thereby enabling the trip lever P,
to be raised or lowered as desired to alter the position of the trip lever, so that the
grain which acts against it will trip it sooner or later, as required. The stop arm L,
which engages with the dog K, is provided with a spring R, for the purpose of
holding the said stop arm in the path of the dog K, except when otherwise acted
upon.
When sufficient grain has accumulated on the binding table to press upon the
trip lever P, with sufficient force to raise the stop arm L, clear of the dog K, the
said dog falls into the path of one of the roller studs G, thus forming a connection
between the spur wheel I, and the revolving packer shaft C, and meshes with the
spur wheel S, which is connected go to the binding mechanism. The said binding
mechanism is put into operation the moment that the dog K is released as stated.
In order to hold the stop arm out of the path of the dog K, while the mechanism
makes the necessary number of revolutions, we form a cam T, on the hub of the
needle N, which cam comes in contact with the roller O, on the arm N, immediately
after the dog has been released, and as this arm N, is fixed to the same spindle M,
as the arm L, the said stop arm L, is held out of the path of the dog K, until the
gear has made the required number of revolutions, when the cam releases the arm N,
and permits the stop arm L, to drop once more into the path of the dog.
V, is a flat spring held at one end to the bracket A, and extending from the path

page_text: of the cam W, which projects from and is fixed to the spur wheel I. This cam
projection is so shaped that the spring will slip past the highest point of it and
assist the spur or driver wheel I, in completing its revolution, so that the end of the
spring shall be behind the cam projection W, and prevent the gear revolving in
the reverse direction.
Having now particularly described and ascertained the nature of the said inven-
tion, as communicated to me by my foreign correspondents, and in what manner
the same is to be performed, 'I declare that what I claim is :-
1. The combination with the binder frame of a bracket extending from the frame
and arranged to form a support for the packer shaft, driving gear, etc.; substantially
as and for the purpose specified.
2. A rectangular frame composed of a bracket A, and bail B, fixed to the frame
below the binder table and arranged to support the packer shaft, the driving and
tripping mechanism of the knotter; substantially as and for the purpose specified.
3. A stop arm arranged to engage with a dog K, and fixed to a spindle suitably
journaled and having a slotted arm projecting from it in combination with a trip
lever pivoted on the spindle of the stop arm and adjustably connected to the
projecting arm; substantially as and for the purpose specified.
4. A stop arm arranged to engage with a dog K, and fixed to a spindle suitably
journaled and having a slotted arm projecting from it in combination with a cam
formed on the hub of the needle; substantially as and for the purpose specified.
5. A stop arm held in the path of the dog K, by a spring R, and fixed to a spindle
suitably journaled and having a slotted arm projecting from it in combination with
a cam formed on the hub of the needle; substantially as and for the purpose
specified.
6. A spring V, fixed to a bracket A, in combination with cam projection W,
fixed to the spur wheel I; substantially as and for the purpose specified.
