An Improved Sheaf Binding Harvester.
We, JOSEPH BISPHAM LEATHER BARROW, of York House, Dickinson Road,
Longsight, Manchester, in the County of Lancaster, Engineer, and THOMAS
BUTLIN MARGETTS, of Flowerdale, Table Cape, Tasmania, Grazier, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:
Our invention relates to an improved construction of sheaf binding harvesters
with the object of improving the means for bundling and tying the sheaves and
dispensing with the packers. For the purpose of more clearly describing the
nature of our invention we have annexed hereunto two sheets of drawings. In
the several views shewn therein similar letters refer to similar parts.
Fig. 1 is a side view showing our invention applied to any ordinary reaping
machine.
Fig. 2 is a plan, and Fig. 3 an end view, but in both of these cases to prevent
confusion the discharging arms and needle with mechanism for tying are omitted.
Fig. 4 is an end view, Fig. 5 a side view, and Fig. 6 a plan of a part of the
machine showing the discharging arms and needle.
The improvement which forms the subject of this invention may be affixed
to any reaping machine such as partly indicated at in which the grain after
being cut falls on to the platform, and is carried up between canvas elevators j
that are supported on rollers j.
In this our invention the grain passes from the elevator and is received on a.
cradle that is formed of a row of semicircular arms b when they are in the
position shown by dotted lines in Fig. 1, said arms being fixed to a cross shaft e
extending from side to side of the frame d, and supported in brackets e¹. A
lever e is fitted to one or both ends of the shaft c; at the inner end of this lever
a balance weight for an equivalent is attached and the opposite or outer end e
is connected by a rod or chain g to a lever k that is fitted on the end of a trans-
verse shaft which is placed above the shaft and parallel thereto. A row of
semi-circular arms 7 are fitted on and depend from the shaft 7 which is pivotted
in brackets as m.
The needle is fitted on the frame so that when encircling the sheaf the
back of the needle is outwards, and the needle eye 22 inwards, or the reverse of
the ordinary position. Any preferred form of knotter may be employed for
binding the sheaf. The binder attachments employed in combination with the
mechanism herein above described may be such as shown or has been in use
hitherto.
In working our invention the inner end of the lever e with the weight for
spring connected thereto will be in the position indicated by dotted lines in
Fig. 1 which will cause the cradle also to be in the position so indicated:
the lever e passes through a slot in the rods whose upper end works in a
guide and the lower end of said rod is connected to the free end of the bar u
which is pivotted to the side of the frame d.

page_text: The end u engages with the catch of the trip when the cradle 6 and the
lever e are in the positions herein before named and prevents action of the trip.
When a supply of grain has been deposited in the cradle having sufficient
weight to overcome the resistance of the weight for spring at the end of the
lever e, the cradle will be lowered to the position shown in full lines in Fig. 1
of the drawings at the same time the opposite end e¹ of the lever e will cause the
shaft to rotate and the guard will be placed in proximity to the elevators
thereby temporarily preventing the grain passing on to the cradle b; the raising
of the weighted end of the lever e withdraws the end of the bar from the
catch thereby permitting the sprocket wheel a to revolve and actuate the
sprocket wheel causing the needle to encircle the sheaf which is then
fastened by the knotter, and the needle withdrawn when the arms discharge
the sheaf from the cradle b which then rises by the action of the weight for
equivalent, the guard g is lifted, the end of the lever engages with the
catch stopping the motion of the sprocket wheels and and the operation
herein before described is repeated.
a is the driving wheel from which power is transmitted in the ordinary
manner to the binder attachments through the sprocket wheel, chain,
wheel, shaft, bevel wheels shaft a² and wheels at and a: 7³ is the
bearing for the needle shaft: the wheel which is fitted on the shaft a drives
the binder attachment is the bearing for the discharge arm and
connection with the sprocket wheel af.

Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. In sheaf binding harvesters the combination with an ordinary reaping
machine in which elevators as are employed, of a guard as a balance lever
or levers as e and a cradle as automatically actuated by the weight of the
grain by which a connection is intermittently formed by levers and with the
binder attachments in the manner shown and described and for the purposes
set forth.
2. In sheaf binding harvesters the combination with mechanism herein before
described of a needle as that is fitted so that the needle point is inwards when
the sheaf is being tied by the knotter in the manner herein described.
