Improvements in Scythes.
I, WILLIAM EDWIN HEYS of 70 Market Street, Manchester in the County of
Lancaster, Patent Agent, do hereby declare the nature of this invention to be as
follows:-
This Invention relates to scythes and it has for its object to enable the blade of the
scythe to be moved to any desired angle relatively to the haft so that it may be
placed in the most favourable position both as regards the work to be done and the
mower.
For the purpose of this invention the blade is secured to the haft by means of an
angle plate attached to the haft by two bolts one of which forms an axis around which
the blade may be rotated. The other bolt passes through a slot in the angle plate. The
angle plate has upon one of its sides à crown wheel with say one hundred teeth.
The heel of the blade has also formed upon or attached to it a similar crown wheel
which engages with the wheel on the angle plate. The two wheels are connected by
a bolt passing through their centres; hence by this arrangement the blade may be
arranged in any one of one hundred different angles relatively to the haft. Since
other positions or angles may be desired for the blade intermediate between those
provided for by the wheels, a slotted gauge plate is placed over the bolt which passes
through the slot in the angle plate, and under the angle plate. By regulating the
position of the guage plate, the angle plate and with it both the wheels may be moved
through a small angle, and by this means intermediate positions for the blade may be
secured. The horizontal angle of the blade may be varied by moving the angle plate
around its pivotting bolt.
The right hand handle is attached to the haft by means of a band secured to the
handle and passing around the haft. A screw is inserted through the band and a
square, nut and abuts upon a pressure piece in contact with the handle. When the
screw is screwed up, the handle is thus secured to the haft, and when it is unscrewed,
the handle may be moved along the haft into any desired position.
The band acts as a safeguard and it is fixed in such a position that when the point
of the blade is brought below the baft it will also be below the centre of the band.

Improvements in Scythes.
I, WILLIAM EDWIN HEYS of 70 Market Street Manchester in the County of
Lancaster, Patent Agent, 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 scythes and it has for its object to enable the blade of the
soythe to be fixed at any desired angle relatively to the haft so that it may be placed
in the most favourable position both as regards the work to be done and the mower.
For the purpose of this Invention the blade is secured to the haft by means of an
angle plate attached to the haft by two bolts one of which forms an axis around which
the blade may be rotated. The other bolt passes through a slot in the angle plate. The
angle plate has upon one of its sides a crown wheel with say one hundred teeth.
The heel of the blade has also formed upon or attached to it a similar crown wheel

by a bolt passing through their centres; hence by this arrangement the blade may
be arranged in any one of one hundred different angles relatively to the haft.
Since other positions or angles may be desired for the blade intermediate between
those provided for by the wheels a slotted gauge plate may be placed over the
bolt which passes through the slot in the angle plate, and under the angle plate.
By regulating the position of the gauge plate, the angle plate, and with it both
the wheels, may be moved through a small angle, and by this means intermediate
positions for the blade may be secured. The horizontal angle of the blade may be
varied by moving the angle plate around its pivoting bolt.
The right hand handle may be attached to the haft by means of a band secured
to the handle and passing around the haft. A screw is inserted through the band
and a square nut, and abuts upon a pressure piece in contact with the handle.
When the screw is screwed up, the handle is thus secured to the haft, and when
it is unscrewed, the handle may be moved along the haft into any desired position.
The band acts as a safeguard and it is fixed in such a position that when the point
of the blade is brought below the haft it will also be below the centre of the band.
These Improvements are illustrated by the accompanying drawings in which Fig. 1
is a partial view of the under side of the blade, Fig. 2 is a partial view of the upper
side, and Fig. 3 is a partial end view.
In each of the Figures A is the angle plate; a is the bolt by means of which
the angle plate is secured to the haft and around which the angle plate may be
turned; a is a second bolt which passes through the slot a" in the angle plate,
so that when this bolt is loosened the angle plate may be moved into any desired
position within the limits of the slot and when it is tightened the angle plate is
securely held. This arrangement enables the mower to fix the edge of the blade
at a greater or less distance from the ground. c is the crown wheel or equivalent
notched plate formed upon or secured to the angle plate and hollowed towards its
centre. D is a similar wheel or notched plate formed upon or secured to the blade.
This wheel or plate is rounded towards the centre and fits into and gears with c.
A bolt passes through the two wheels and when tightened up secures the blade
firmly to the haft; when the bolt is loosened, the wheels may be lifted out of gear
and the position of the blade be altered as desired.
Having now particularly described and ascertained the nature. of my said Inven-
tion and in what manner the same is to be performed, as communicated to me
from abroad, I declare that what I claim is :-
(1) The herein before described method of and means for adjusting the edge of the
blade of a scythe at a greater or less distance from the ground; substantially as set
forth and as illustrated by the accompanying drawings.
(2) The herein before described method of and means for adjusting the angle of a
scythe relatively to its handle; substantially as set forth and as illustrated by the
accompanying drawings.
(3) In and in connection with a scythe; the combination and arrangement of the
slotted angle plate secured to the handle by two bolts, with two crown wheels or
equivalent notched plates one of which is fixed to the angle plate and the other to the
heel of the blade both of which are held together normally by a bolt passing through
their centres; substantially as and for the purpose hereinbefore described and as
illustrated by the accompanying drawings.
