PROVISIONAL SPECIFICATION.
Improvements in Sheaf Binding Harvesters.
We, JAMES HORNSBY, and JOHN INNOCENT, both of Spittlegate Iron Works,
Grantham, in the County of Lincoln, Engineers, do hereby declare the nature of
this invention to be as follows:-
This invention relates to the mechanism by which the cut crop is arranged ready
to be bound into sheaves.
It has before been proposed to employ what is known as a buttor for passing the
stubble end of the cut crop from the elevators to the place where the sheaf is
bound, and for levelling the butt end of the sheaves.
The buttor is usually composed of a piece of board or sheet iron with projecting
pieces on the side next the crop and it is operated at one end by a crank whilst its
other end reciprocates to and fro.
According to this invention we support the end of the buttor furthest from the
crank on a crane shaped bar pivotted to the bracket carrying the crank. This bar
can be turned about its pivot so that when the buttor is at work the end of the
buttor against the sheaves may be adjusted to suit the length of the crop being
bound, this adjustment is effected by a suitable rod pivotted to the upper limb of
the crane.
Near its outer end the crane bar is cranked downwards and is then
again bent horizontally, the latter horizontal part of the bar carrying a sliding
bracket jointed to a bracket fixed to the buttor.
To part or separate the bound and the unbound portions of the crop we employ
above the crop a prong or prongs fixed to a horizontal bar caused to oscillate as
each sheaf is bound. The end of the bar is turned upwards to form a crank to the
end of which is pivotted a connecting rod whose other end is pivotted to a bracket
mounted on the knotter spindle. The knotter spindle makes one revolution and
the separating prongs therefore oscillate once for each sheaf that is bound. When
the prongs are in their normal position they are above the crop and do not intercept
it as it is passed forward to be bound, but when there is sufficient grain to form a
sheaf and the binding mechanism is started the needle in passing round the sheaf
makes a division between the sheaf and the unbound grain and into this division
the separating prongs are moved and press the unbound grain away from the back
of the needle so that the needle is free to pass around the sheaf and return without
the unbound grain being forced against it.
The separating prongs also prevent the unbound grain being dragged away by
the sheaf as it is discharged as sometimes happens when the crop is tangled.

DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation and Figure 2 a plan of part of a harvester shewing the
buttor.
a a are the clevator canvasses and a' a' their rolls, these deliver the cut crop onto
the roll b. c is the buttor consisting of a board having on the side next the cut
crop inclines c. At one end of the buttor is fixed a casting d having on it a
bearing which receives a crank pin e on a crank ¹ fixed to a crank shaft e² to
whose other end is fixed a bevel pinion e gearing with a bevel pinion b' at the end
of the roll b. In Figure 1 the crank is shewn at its extreme right hand position
and at Figure 2 in its midway position. f is a bracket fixed to the buttor and
having pivotted to it the tube which receives the end of the crane shaped bar g.
This bar is bent as shown in Figure 1 and its other end works in bearings hon
the bracket h to which is fixed the tube 2 in which the crank shaft e works. k is
the binding table. is a rod for adjusting and holding in position the crane shaped
bar 9. It will be observed that both the supports of the buttor namely the
castings d and f
are on its centre line so that no twisting strain is thrown on the
Figures 3 and 4 are perspective views of the machine showing the prongs m fixed
to the horizontal bar m² having its end m³ turned up to form a crank to which is
pivotted the connecting rod n whose other end is pivotted to the bracket o¹ on the
knotter spindle o. The prongs m therefore oscillate once for every revolution of
the knotter spindle. In Figure 3 they are shewn turned up into an approximately
horizontal position out of the way of the stream of cut crop and in Figure 4 they
have been turned down onto the binding table k so as to push back the cut crop
away from the needle p and thus prevent it from pressing against its back. In
these figures the buttor is omitted and the other parts of the machine are of
ordinary construction and require no description.
bearings of the crank.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we wish it to be understood
that we do not claim generally a buttor whose direction can be adjusted to suit the
length of the crop being bound nor do we claim generally an interceptor to prevent
the cut crop from pressing on the back of the needle but we declare that what we
claim is :-
1. A buttor hung from two points upon its centre line one support being adjust-
able round the other substantially as described.
2. The pivotted crane shaped bar g for supporting the buttor substantially as
described.
3. The arrangement substantially as described and shewn at Figures 1 and 2 of
the drawings.
4. Pushing the cut crop away from the back of the needle substantially as
described.
5. The prongs m and means for actuating them substantially as described and
shewn at Figures 3 and 4 of the drawings.
