An Improved Device for Fastening Scythes to Scythe-poles.
A communication by CARL FRIEDRICH LUDWIG GRABNER, of 43, Schwartauer
Allée, Lübeck, in the Empire of Germany, Gardener.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors 6, Lord Street, Liverpool, and 6, Bank Street
Manchester, both in the County of Lancaster and 323, High Holborn, in the
County of Middlesex, Civil 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 :-
This invention has for its object an adjustable double screw device to enable a
scythe blade to be fastened to the scythe pole in an easy and simple manner, and
to render it possible to rapidly and easily release or unfasten the scythe blade from
the pole when it is desired to sharpen it.
The invention is shown in the accompanying drawings,
Figure 1 being a view in perspective of the adjustable double screw device.
Figure 2 a section through the upper end of the scythe pole.
Figure 3 a view of the scythe pole with the double screw apparatus attached.
This improved double screw device consists essentially of two closed loops a
and b, which are adjustably connected with one another above and below by means
of bars c d e d'. Each of the bars c d' has a slot, whilst the others c¹d have a
fixed pin rivetted on, which, being easily adjustable in their slots, allow the two
loops a and b to be adjusted to or from one another. In the centre of the semi-
circular part of the loops, are inserted screws e and e¹ which allow the loops to be
fastened to the scythe pole. A plate, which is shown in section in Figure 2 and
is attached to the end of the scythe pole, prevents the screws e e¹ from penetrating
into the wood of the same. The scythe A, which has a tang g bent at the end in
the form of a hook in the usual way, is attached to the scythe pole B by means of
the new double screw device in the following manner :-
The scythe pole is first levelled off a little at the side where the part g is to fit,
and opposite this flattened part the plate f is firmly screwed by means of wood
screws. The adjustable double screw device is then passed over the scythe pole in
such a way that the rounded part of the latter comes to lie with the plate funder
the screws e and e¹ as shown in Figures 2 and 3. The tang g is then laid on the
end of the scythe pole, the loops a and b are drawn apart to correspond with the
length of this tang 9, and by means of the screws e e¹ the tang 9 is strongly
clamped onto the scythe pole B. A wedge k may also be preferably inserted
between the tang g and the loops a and b, but this is not absolutely necessary, and
the parts a and b may rest directly on g. If it be desired to release the scythe
from the scythe pole, it is only necessary to slacken the screws e and e', and to draw
the wedge and tang out of the adjustable double screw device.
Having now particularly described and ascertained the nature of the said inven
tion, 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 :-
An adjustable double screw device for fastening a scythe to the scythe pole,
consisting of two loops mutually adjustable and provided with set screws and
counter plate with the object of producing, by tightening the set screws, a firm

page_text: clamping of the tang of the scythe to the scythe pole, the counter plate f preventing
any penetration of the set screws into the wood, substantially as herein before
described and shown on the accompanying drawing.
Dated this 11th day of July 1894.
