Improvements in the Construction of Sheaf Binding Harvesters.
I, ERNEST SAMUELSON of Banbury in the County of Oxfordshire, Engineer do
hereby declare the nature of this invention to be as follows:-
My invention relates more particularly to that type of Sheaf Binding Harvesters
which is technically known as a "Low-down" machine as described in my pre-
vious patent No. 16,818-1893, and consists in making the upright gavelling
chamber which extends from the platform to the binding table, expansible, so
that when working in heavy crops, the space in the gavelling chamber through
which the grain passes becomes automatically enlarged to allow of the free passage
of the grain to the binding table, and I effect this by placing springs behind the
upright gavelling chamber so that it may bodily move outwards, or by hinging
it at the lower end with a spring attachment at the upper, or by placing a series
of springs inside the chamber which will yield to the pressure of the grain.
I also arrange a spring or an equivalent yielding arrangement under the needle
plate, so as to relieve the latter of any extra pressure of the grain in its passage
under same to the needle.

I, ERNEST SAMUELSON of Banbury in the County of Oxfordshire, Engineer 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:

page_text: I illustrate in the accompanying drawings the manner in which I carry these
Improvements into effect.
The general arrangement of the machine is, similar to the drawings shown in
my Patent No. 16,818 1893, and I have used the same letters to denote similar
parts in the two specifications; A, being the main travelling wheel, C, the endless
travelling apron known as the platform, D), the revolving drum fitted with a series
of projecting fingers or hooks 'D', D', D',
which take the cut corn
from the travelling apron C into the upright gavelling chamber E, E, which is
formed by the series of guard irons H, H, ... supported in position by a fixed
portion of the framing of the machine as shown in Fig. 3A, and the sheet iron H¹, H
from whence it is taken to the binding table by suitable mechanism, and bound
into sheaves as described in my previous patent 16,818-1893, and my
Improvements consist.
at H³, H2,"
Firstly in making this upright gavelling chamber E, E, expansible by placing
springs S, S,
as shown in Fig. 1 behind the guard irons H, H,
which form one side of the upright gavelling chamber, so as to allow
'them to yield or move bodily outwards as shown by dotted lines, or, as an alternative
I hinge the guard irons H, H,
and place behind them
springs S, S,
may radiate out-
wardly, and so increase the space in the upper portion of the gavelling chamber
as shown in Fig. 2 in full and dotted lines, or, as another alternative, I make the
guard irons H, H,
fixed, but insert in the gavelling chamber E, E,
which will yield to the pressure of the grain,
so that the bars H, H,
a series of springs S, S,
as illustrated in full and dotted lines in Figs. 3 and 3A.
The second portion of my Improvement is shown in Figs. 4, 4a, 5, 5a, and
consists of a spring or springs J, J, fixed to the needle plate J, so as to yield
when necessary to the flow of grain as it passes from the gavelling chamber E, E,
to the binding mechanism on the top of the table H¹. These springs may be as
shown in Figs. 4, and 4a, of flat section, curved and fixed at one end of the needle
plate by bolts or other suitable means; or, instead of using flat springs I make
the needle plate in two portions, the upper portion. J as before, with a hinged
portion J2, which radiates on pins J, J, carried by lugs J, J3, on the needle
plate J, and at the other end kept in its normal working position by means of a
bolt J5, and a spring Jo, as shown in Figs. 5, and 5a.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
.
1st. In Lowdown Sheaf Binding Harvesters of the form shown and described
in my Patent 16,818-1893 making the upright gavelling chamber E, E, expans-
ible by means of springs attached to the upright guard irons which form part of
the said chamber, or by placing springs inside the said chamber.
2nd. In Sheaf Binding Harvesters and more especially Harvesters of the type
of Low-down machine forming the subject of my Patent 16,818-1893, making
the under-side of the needle plate so that it may yield to the pressure of the grain
as shown.
3. In Low-down Sheaf Binding Harvesters the combination of an upright
expansible gavelling chamber, and a yielding needle plate as shown and described
in accompanying drawings, or in an equivalent manner.
