Improvements in Bundle Discharging Mechanism for Harvesting
Machines.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45, Southampton Buildings, in the County of Middlesex, 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 the bundle discharging mechanism of self binding
harvesters for grain, corn, and other crops, and particularly to that class of
machines where the knotter operating mechanism is driven by an intermittingly
operating shaft located above the deck or table on which the grain is bound,
and it has for its object to discharge the bundles from the binder without
danger of the straws being caught in the discharging mechanism and wound on
the shaft, and without tendency to carry the bundles up and 'over the shaft by
the action of the discharging arms.
The invention is illustrated in the accompanying drawings wherein Figure 1
is a perspective view, Figure 2 an end elevation, and Figure 3 a side view of
a part of the binder deck and frame of a self binding harvester fully illustrating
my discharging mechanism and the manner of operating the same.
In these views A denotes a part of the binder frame casting, C the knotter
operating shaft journalled therein, B a pipe rail by means of which the breast
plate D is connected with the frame of the machine. E denotes the binder deck
and F the usual drop leaf at its outer end. The knotter operating mechanism G
may be of any desired construction, that shown in the drawings being of a
type that is now well known.
"
On
The shaft C immediately adjacent the knotter operating wheel is cranked as
at c, and a vibrating discharge fork or arm H is sleeved about midway of its
length upon the pin of this crank. The upper end of the arm H is connected by
means of a link with the pipe rail B or other fixed part of the machine.
the opposite side of the knotter mechanism from the crank c, the shaft C is
provided with a removable crank arm I, the same being secured on the end of
the shaft by means of nuts i. This arm I extends radially from the shaft in
line with the cranked part c, and on a projection at the outer end of the arm is
sleeved another discharge fork or arm H which is similar in construction to the
fork H and is likewise link-connected at its upper end with the pipe rail B
by a pivoted link rod h.
These two discharge arms H, H¹, act in unison on the bundle, and as the
knotter operating shaft C revolves they describe the elliptical path indicated by
the dotted lines 1 in Figure 2, and this forms an efficient mechanism for the
purpose described. It is often desirable, however, in this class of machines,
to be able to turn the shaft C by hand for the purpose of threading up the

page_text: binder or forcing out a bundle by hand. This cannot conveniently be done
by means of the arms H, H', and I therefore provide the outer end of the
crank I with an outwardly projecting and rearwardly curving arm J which
acts as an auxiliary discharger, but which rotates with the arm I and describes
the path indicated by dotted lines 2 in Figure 2. This arm J practically forms
a continuation of the arm I, and is secured to or itself forms the projection at
the outer end of the arm I on which the fork H¹ is journalled, and these arms
are preferably so positioned and timed with respect to one another that all three
shall strike the bundle at about the same time, but so that the rotary arm J
shall gain on the non-rotary ones as the bundle is moved outwardly. This
increased movement of the rotary arm causes the head portion of long bundles to
be thrown well out of the binder, and effects a clean separation of the head
portion of the outgoing bundle from the unbound grain which for the time
being is in the binder. The position of the arm J relative to the non-rotary
arms H and H' may be adjusted by securing the former at different angles upon
the outer end of the arm I.
Having now particularly described and ascertained the nature of this 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 a self binder, the combination of the knotter operating shaft, one or
more non-rotatable bundle discharging arms, and a rotatable discharge arm
carried by the shaft.
2. In a self binder, the combination of a rotary shaft having cranks, one or
more non-rotatable discharge arms mounted on the cranks, and a rotatable dis-
charge arm carried by the shaft.
3. In a self binder, the combination of a rotary shaft having cranks, discharge
arms journalled on said cranks about midway of their length, and-controlled-in-
their movements by links connected with their upper ends, and a rotary discharge
arın rigidly connected to said shaft.
4. In a self binder, the combination of the rotary knotter operating shaft,
cranks on said shaft on which are sleeved elliptically moving discharge arms,
and a rotary discharge arm secured to one of said cranks.
5. In a self binder the combination of the shaft C cranked at c and the
arm I, of the discharge arms H, H¹ journalled midway of their length upon the
pins of said cranks and connected at their upper ends to a fixed part of the
machine by links, and the rotary discharge arm J rigidly secured to the crank
pin of the arm I.
