PROVISIONAL SPECIFICATION.
Improvements in the Method of Reducing Wire for Cycle Spokes,
Sewing Machine Needles, Hackle Pins, and other purposes.
I, WILLIAM KENDALL of Ragley Mills Alcester in the County of Worcester,
Manufacturer do hereby declare the nature of my said invention to be as
follows:-
My invention has for its object improvements in the method of reducing wire for
cycle spokes sewing machine needles, hackle pins and other purposes whereby I am
enabled to greatly cheapen the production and improve the quality and finish, and
cycle spokes manufactured according to my invention which I am about to explain
will stand a higher tension or strain than those as at present manufactured.
In carrying my invention into practice I take two dies and cut a groove in the
centre of the face of each which has been previously rounded and formed at a
slight angle. I then grind the top side of the end of each die nearest to the face
so as to form a cutting edge at the top end of each groove. These dies are then
set in a machine and the wire, when making cycle spokes, is cut to the necessary
length, and headed then fixed in the machine which when set in motion causes
the spoke to travel backwards and forwards between the two grooved dies. The
cutting edges of the dies evenly cutting or reducing the spokes to within a
short distance of either end and at the same time imparting a good finish
and polish so that when it leaves the machine it is in a perfectly finished
state.
Instead of forming a cutting edge at the top end of each groove I may make
it slightly rounded in which case when the wire passes between to be reduced it
will be drawn out instead of being cut and this method gives a higher polish or
finish to the spoke.

Improvements in the Method of Reducing Wire for Cycle Spokes,
Sewing Machine Needles, Hackle Pins, and other purposes.
I WILLIAM KENDALL of Avenue Works Astwood Bank Redditch late of
Ragley Mills Alcester in the County of Worcester Manufacturer do hereby
declare the nature of my said invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement :-
My invention has for its object improvements in the method of reducing wire
for cycle spokes, sewing machine needles, hackle pins and other purposes whereby
I am enabled to greatly cheapen the production and improve the quality and finish,

page_text: and cycle spikes manufactured according to my invention which I am about to
explain will stand a higher tension or strain than those as at present manufactured..
In order that my invention may be clearly understood and easily carried into
practical effect I have appended hereunto a double sized sheet of drawings upon
which I have illustrated an example of my method of reducing wire and also
several modifications of my tools.
Figure 1 is a side elevation shewing the arrangement for drawing the wire
through the tools.
Figure 2 is an enlarged view of part of the tools.
Figure 3 is a front view of part of my tools shewn in a modified form.
Figure 4 is a side sectional elevation of Figure 3.
Figure 5 is a plan view shewing the groove in the tool tapered.
Figure 6 is a side sectional elevation of part of my tools with a rounded instead
of a cutting edge.
In carrying my invention into practise I mount the slide A on the bed B which
is operated by the lever C. This lever is pivotted at one end to the slide and at
the other end to the short arm or lever D which is fixed on the shaft d on which
the toothed wheel d is keyed. This toothed wheel gears with the worm E formed
on the shaft e¹ on which the fast and loose pulleys Fare fixed. Mounted in
bearings at each end of the slide are the small jaws or chucks a' and a for holding
the wire W as it is operated upon by the reducing tools G and G' which are held
in the chucks H and H.
When forming the reducing tools I take two dies and cut the parallel groove g
in the centre of the face of each which has been previously formed at a slight
angle with the portion 93 at the front of each edge cut away as shown at Figures 1
& 2 or I may form them as shown at Figures 3 and 4. I then grind these ends of
the tools so as to form a cutting edge on the front end of each groove. After
these tools or dies have been fixed in the chucks as previously described the
machine is set in motion the action of which causes the short lever D to revolve
carrying with it the end of the lever C which moves the slide A backwards and
forwards thereby drawing the wire between the dies. When the slide reaches the
end of its backward movement the pawls or catches J and J which take into
the teeth of the ratchet wheels K and K are operated by a series of cams,
or in any other suitable manner thereby causing the chucks and the wire to turn
slightly by which means it is evenly reduced to within a short distance of either
end and at the same time a good finish and polish is imparted to it so that when it
leaves the machine it is in a perfectly finished state.
At Figures 5 and 6 I have shown a modification of my tools. In the method as
shown at Figure 5 I form the groove 9' taper instead of parallel. In some cases
instead of forming the groove with a cutting edge I form it slightly round as
shown at g Figure 6 which draws the wire out instead of cutting it as it passes
between the tools.
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 :-
First. The improvements in the

CLAIMS.
First. The improvements in the meshed of reducing wire for cycle spokes,
sewing machine needles, hackle pins and other purposes consisting essentially of
two tools or dies such as G and G¹ held in chucks mounted on a stationary bed
while the wire to be reduced is drawn between in the manner substantially as
herein before described and as shewn upon the accompanying sheet of drawings at
Figure 1.
Second. Tools or dies for reducing wire formed with a groove on the face
of each either parallel or taper and a cutting edge at the front of each groove

as shewn upon the accompanying sheet of drawings, at Figures 3 to 5 inclusive.
Third. Tools or dies for reducing wire formed with a groove on the face of each
either parallel or taper in the manner and for the purpose substantially as
hereinbefore described and as shewn upon the accompanying sheet of drawings at.
