PROVISIONAL SPECIFICATION.
Improved Rolls for Rolling Scythe Blades.
I, HARRY PERRINS, of Sidney Valley, Great Elm, Frome, in the County of
Somersetshire, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in rolls applicable to scythes.
The object of this invention is to roll the scythe from the end to the point. by
the mould constructed in the rolls, instead of forging the scythe plate under a
hammer.
This invention is constructed with a series of rolls mounted in housings, the said
rolls being parallel with its axis. The top set of rolls are formed with a plain face
on their periphery. To the bottom set of rolls I cut one or more moulds in the
periphery of the said rolls in order to form the "pass" this said "pass" being so
cut, and as the rolls revolve the "pass" will form the scythe when the metal is
inserted by one revolution of the said rolls.
It will be understood that the foregoing is given by way of illustration, and
that the shapes and parts may be varied in many ways within the scope of my
invention.

COMPLETE SPECIFICATION.
Improved Rolls for Rolling Soythe Blades.
I, HARRY PERRINS, of Sidney Valley, Great Elm, Frome, in the County of
Somersetshire, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :—
My invention relates to improvements in rolls for rolling scythe blades.
The object of this invention is to roll the scythe from the end to the point by
the mould constructed in the rolls, instead of forging the scythe plate under a
hammer.
This invention is constructed with a series of rolls mounted in housings, the said
rolls being parallel with its axis. The top set of rolls are formed with a plain face
on their periphery. To the bottom set of rolls I cut one or more moulds in the
periphery of the said rolls in order to form the "pass" this said "pass" being so
cut, and as the rolls revolve the "pass" will form the scythe blade when the metal
is inserted by one revolution of the said rolls.
The accompanying drawing illustrates the design in elevation, with the housings
described by dotted lines, reference being had to letters.
"
In carrying out my invention I fix the top rolls a, b, c, and d, on a shaft h, and on
the bottom shaft i I fix the bottom rolls j, k, l, and m, the said rolls being parallel
with its axis and mounted in housings g. The top rolls a, b, c, and d, are formed
with a plain face on their periphery. To the bottom set of rolls j, k, l, and
my I
cut moulds n in their periphery of the said rolls in order to form the " passes,
these said "passes "being so cut, and as the rolls revolve one
pass" will form
the scythe blade. Thus the mould is cut in the rolls at o and finish at the point e.
Four grooves or moulds n are shown on the drawing to indicate the various
positions, but only one set of rolls a, and k, are required to roll the soythe
blade

page_text: The blank is inserted in the pass f and roll a commences to roll the blade, 6 the
middle of the blade, a near the point and d the end of the point, these rolls are
shown on the drawing for the purpose of indicating the various positions of the
mould as one pair of rolls revolve.
It will be understood that the foregoing is given by way of illustration, and
that the shapes and parts may be varied in many ways within the scope of my
invention.
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 :-
1. The combination of the top roll a, and the bottom roll k, with the mould n cut
in the roll k, for rolling scythe blades from the end to the point, substantially as
herein described and according to the accompanying drawing.
2. The process of forming a scythe blade from a blank inserted in the "pass" as
the rolls revolve, substantially as herein described.
