I, GEORGE DYSON OWEN of Selwood Rotherham in the County of York, Engineer
do hereby declare the nature of the said invention to be as follows:-
The spokes which are employed in making iron or steel wheels are usually pieces of
bar thicker and wider in their middle parts than at each end, and these bars are bent
so that their middle parts become united to the rim of the wheel while the two end
parts are engaged in the boss. These bars are lengths cut off from a bar rolled with
thickened parts but of uniform width, and the narrowing of the two end parts of each
length cut off involves considerable labour in forging or other operations. This
invention relates to apparatus whereby the narrowing of one of these bars at each end
is rapidly and economically performed. For this purpose, I fit into the ram head of
a hydraulic or other forging press two parallel shear blades with an open space
between them equal to the width which the spoke bar is intended to have in its end
parts, and on the anvil or bed of the press I fix a bolster or die of the same width.
I lay on this bolster the bar that has to be narrowed and then the shear blades
descending cut off from the bar two strips of metal, one on each side leaving the
middle part of the bar of the required width. When one end of the bar is thus
treated, it is turned end for end and the other end is treated in the same way. Or, in
cases where the press is of sufficient size and power, there may be two pairs of shear
blades fixed in the head at a distance apart equal to the length of the wide middle of
the spoke bar, and both ends may be operated on simultaneously.
Dated this 2nd day of December 1886.

Apparatus for Shaping Spokes for Iron or Steel Wheels.
1, GEORGE DYSON OWEN of Selwood, Rotherham in the County of York, 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:
The spokes which are employed in making iron or steel wheels are usually pieces
of bar thicker and wider in their middle parts than at each end, and these bars are
bent so that their middle parts become united to the rim of the wheel while the two
end parts are engaged in the boss. These bars are lengths cut off from a bar rolled
with thickened parts but of uniform width, and the narrowing of the two end parts of
each length cut off involves considerable labour in forging or other operations. This
invention relates to apparatus whereby the narrowing of one of the bars at each end
is rapidly and economically performed, as 1 will explain referring to the accompanying
drawing Fig. 1 is a plan of a spoke bar S which is in the first place rolled of uniform
width but has to be made narrower at the end parts E.
I fit as shown in the section Fig. 2 into the ram head A of a hydraulic or other
forging press two parallel shear blades B B with an open space between them equal
to the width which the spoke bar is intended to have in its end parts E, and on the
anvil or bed C of the press I fix a bolster or die D of the same width.
I lay on this bolster the bar S that has to be narrowed and then the shear blades B
descending cut off from the bar two strips of metal e e one on each side leaving the
middle part of the bar of the required width. When one end of the bar is thus
treated, it is turned end for end and the other end is treated in the same way. Or in
cases where the press is of sufficient size and power there may be two pairs of shear
blades fixed in the head at a distance apart equal to the length of the wide middle of
the spoke bar, and both ends may be operated on simultaneously.
Having now particularly described and ascertained the nature of this invention
and in what manner the saine is to be performed I declare that what I claim is:-
For shaping spokes for iron or steel wheels in combination with a forging press,
two parallel shear blades and a bolster, arranged and operating, as herein described.
