PROVISIONAL SPECIFICATION.
New or Improved Machine for Forming Heads on Wire Spokes for
Bicycle Wheels or on Lengths of Wire for other purposes.
I GEORGE ELLIOTT of 17, Alderson Place Highfields, Sheffield, in the County
of York, Mechanical Engineer, do hereby declare the nature of this invention
to be as follows:-
My present invention relates to a new or improved machine for forming heads
upon wire spokes for bicycle wheels, or upon lengths of wire for other purposes,
the object being to so combine a holding die with mechanism for pressing, hammering
or stamping the heads to required size and shape that the said heads are formed as
quickly as it is possible to feed the lengths of wire to the machine; for this
purpose I arrange a die carrier which has an oscillating jaw attached or fixed to a
shalt which receives a rocking motion, so as to move one part of the die away from
the other for the reception of the end of a piece or length of wire, and subsequently
closes when immediately a hammer press or stamp forces the head into shape within
the die, and the die then opens for the withdrawal of the wire so headed. The
improved combined mechanism and arrangement of my new or improved machine
will be understood by the following description.
I form a bed or frame of suitable height and shape, horizontally within which
I arrange a shaft which bears at the fore end in a bracket adjustably secured to the
front of said bed, and also at the back part made with or secured to the
machine.
This horizontal shaft has keyed to it near its fore end the boss of one half of the
die carrier, and it bears freely in the boss of the other half of said die carrier,
which latter is fixed in stationary position to the bed of machine by a set screw or
bolt.
The upper part of the die carrier is recessed or grooved for the reception of the
split or divided die, and set screws are arranged to pass through lugs for adjusting
the lateral positions of the halves of said die.
The horizontal or rocking shaft extends the length of the machine or thereabouts,
and has keyed or otherwise secured to it at its back end a crank or lever which is
arranged with a runner or similar device to bear against the face of a cam fitted to
the driving shaft of the machine thereby imparting to the horizontal shaft the
desired rocking motion.
The said runner may run in grooves formed in said cam, or the end of crank or
lever may be kept pressed thereto by a weight or spring as will be obvious.
The upper part of the bed immediately at the back of the die box or carrier is
arranged with an adjustable horizontal groove, within which works the press
hammer or stamp head, which is caused to strike or press the end of wire within
the die when the wire is firmly gripped by said die. The said press haminer or
stamp is connected to or made with a rod or extension which bears in a circular or
other suitably shaped bearing made with or attached to the top of bed, and its end
receives a runner against which bears the tappet end of a vertical lever which is
fulcrummed upon an adjustable pin carried in two adjustable brackets secured to
the back of the bed, and the opposite end of said vertical lever receives a runner or
a similar device which bears on the peripheral part of the before describel cam,
which peripheral part has a cam shaped projection in order to give the vertical
lever the required throw so that the tappet end drives home the hammer press or

page_text: stamp at each revolution, and the cam is so arranged that the vertical lever aforesaid
only receives motion when the die grips the wire.
The driving shaft runs at right angles to the horizontal shaft and is carried in
bearings or pedestals inade with or fitted to the machine and the cam is adjustable
thereon by a key or screw, and the position of said shaft is adjustable by collars
and an adjustable bush.
A fast and loose pulley or driving mechanism may be arranged on said driving
shaft at any desired and convenient part.
In order to keep the hammer press or stamp away from the die when allowed by
the tappet end of the vertical lever I secure within the bed and so as so stride the
horizontal shaft a fork shaped spring the top part of which bears against a projection
on the slide and the lower parts are coiled round pins secured to the bed and their
ends extend to stops screwed to the said bed as will be well understood.
Where preferred the movable boss of the die carrier may extend the full length
of the horizontal shalt and the rocking lever or crank may be secured thereto
instead of to the shaft. The whole of the working parts of my said improved
machine are adjustable.

New or Improved Machine for Forming Heads on Wire Spokes for
Bicycle Wheels or on Lengths of Wire for other purposes.
I GEORGE ELLIOTT of 17 Alderson Place Highfields Sheffield in the County
of York Mechanical 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 :-
My present invention relates to a new or improved machine for forming heads
upon wire spokes for bicycle wheels, or upon lengths of wire for other purposes,
the object being to so combine a holding die with mechanism for pressing
hammering or stamping the heads to required size and shape that the said heads
are formed as quickly as it is possible to feed the lengths of wire to the machine;
for this purpose I arrange a die carrier which has an oscillating jaw attached or
fixed to a shaft which receives a rocking motion so as to move one part of the die
away from the other for the reception of the end of a piece or length of wire and
subsequently closes when immediately a hammer press or stamp forces the head
into shape within the die and the die then opens for the withdrawal of the wire so
headed.
The improved combined mechanism and arrangement of my new or improved
machine will be well understood by reference to the accompanying sheets of
drawings and the following description thereof.
Fig. 1 is a plan of my said improved machine.
Fig. 2 is a longitudinal sectional elevation taken on line a a of Fig. 1 and
Fig. 3 is a cross sectional elevation taken on line 6b of Fig. 2.
Fig. 4 is a front end elevation and Fig. 5 is a back end elevation of said
machine.
Similar letters of reference denote corresponding parts in each view.
I arrange a die carrier C which has an oscillating jaw c¹ attached or fixed to a
shaft D which receives a rocking motion so as to move the part of the die F
away from the part of said die F for the reception of the end of a piece or
length of wire H and subsequently closes when immediately a hammer press or
stamp J forces the head ' of said wire into shape within the die F and the die F

page_text: then opens for the withdrawal of the wire so headed. The improved combined
mechanism and arrangement of my new or improved machine will be fully
understood by the following description reference being made to the accompanying
drawings.
I form a bed or frame K of suitable height and shape horizontally within which
I arrange the shaft D which bears at the fore or front end in a bracket L and at
the back part in a bearing K' preferably made with the frame K.
The shaft D
has keyed to it near its fore end the boss c² of one half c¹ of the die carrier C and
said shaft D bears freely in the boss of the other half of said die carrier C which
latter is adjusted to stationary position upon the bed or frame K by a set screw c³
or similar device.
The oscillating part e' of the die carrier C may also be adjusted as to its travel
of oscillatory movement by a set screw e as shown Fig. 4. The upper part of
the die carrier C is recessed or grooved at c for the reception of the split or divided
die F and screws m² are arranged to pass through lugs m³ for adjusting the lateral
positions of said halves of die F. The rocking shaft D extends the length of the
machine bed K or thereabouts and has keyed or otherwise secured to it at its back
end a crank or lever N which is arranged with a runner n¹ or similar device to bear
against the face of a cam O which is secured to the driving shaft P of the machine
thereby imparting to the shaft D the required rocking motion.
It will be obvious that the weight of the crank N will keep the runner n¹ pressed
constantly against the face of cam O but where desired a spring or springs may be
employed for this purpose.
The upper part of the bed K immediately at the back of the die carrier C is
arranged with an adjustable horizontal V groove S within which works a slide T
which has a straight groove t' and a cross groove t for the reception of a press
hammer or stamp head J which is caused to strike or press the end of wire H within
the die F when the said wire H is firmly gripped by the said die.
The said press hammer or stamp J receives its motion from a rod V which bears
in a circular or other suitably shaped bearing v made with or attached to the top
of bed K and its end receives a runner ² against which bears the tappet end w¹ of
a vertical lever W which is fulcrumed upon a pin w³ carried in two brackets or
sides k preferably made in one with the back part of bed K and the opposite end
of said vertical lever W receives a runner w³ or similar device which bears upon
the peripheral part o' of the cam O and the part o¹ receives a cam shaped
projection o in order to give the lever W the required throw so that the tappet
end drives home the hammer press or stamp J by the medium of the rod V and
runner at each revolution of the driving shaft P and the cam part o³ is so
arranged that the lever W only receives motion when the die F grips the wire H.
The driving shaft P runs at right angles to the oscillating shaft D and is carried
in bearings or pedestals p¹ made with or fitted to the machine bed K and the cam O
is secured thereon by a key or screw and the shaft P preferably receives a fly
wheel p. A fast and loose pulley p* p* or other driving mechanism may be arranged
on said driving shaft P at any desired and convenient part. In order to keep the
hammer press or stamp J away from the die F when allowed by the tappet end w
of the lever W I secure within the bed K and so as to stride the shaft D an
inverted Ushaped spring Y the upper part of which bears against or within the
slide T and the lower parts are coiled round and secured to the bed K by means of
a bolt y' as shown Fig. 3.
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. In a machine for forming heads upon wire spokes for bicycle wheels or upon
lengths of wire for other purposes. The combination of a die carrier C one half ct
of which oscillates so as to open and close the die F with shuft D lever N and cam
substantially as described.

page_text: 2. In a machine for forming heads upon wire spokes for bicycle wheels or upon
lengths of wire for other purposes the combination with a die carrier C having an
oscillating part c¹ and carrying a die F of mechanism consisting of a slide T
spring Y hammer or press J rod V tappet lever W and cam O substantially as
described.
3. A machine combined and arranged substantially as described and illustrated
and for the object specified.
