Improvements in Machines for Making Wire Spokes and like
Articles Requiring to have a Reduced Diameter for a Portion
of their Length.
I, JAMES YATE JOHNSON of 47 Lincoln's Inn Fields in the County of
London Gentleman do hereby declare the nature of this invention (which has
been communicated to me from abroad by George Joseph Capewell and William
George Allen both of Hartford Connecticut, in the United States of America,
Machinists) and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention has reference to the manufacture of wire spokes for wheels of
bicycles and other vehicles, and similar articles requiring to have a reduced
diameter for a portion of their length, and its principal object is to accomplish the
production of these articles in a rapid and economical manner.
Spokes for bicycle wheels are made from steel wire, and the principal qualities
required of them are lightness and strength. The wire stock, from which the
spokes are made, is cut up into pieces of suitable length (considerably shorter than
the length of the finished spoke) and the thickness of the piece is then reduced for
the greater portion of its length, leaving the ends of larger diameter, this
reduction of diameter being attended by the elongation of the piece. One end
is then threaded for engagement with the rim of the wheel, and the other is
usually provided with a head by means of which it is connected to the hub of the
wheel.
The most effectual means heretofore applied for reducing the middle portion of
the spoke, is by swaging in a machine similar to needle swaging machines, the wire
being subjected to repeated and very rapid blows from vibratory dies, these dies
being reciprocated by a series of balls or rollers carried in a ring-shaped support
and successively acting upon the rear ends of the dies.
The result of this operation is, besides reducing and elongating the wire, to
compress the fibre, and to impart to the surface a high-polish. The operation, of
course, is comparatively slow, admitting of the production of about one spoke a
minute. Moreover, in reducing, by this means, the diameter of the wire to the
required extent, the compression of the metal and the concussion to which it is
subjected are likely to be carried further than the limit at which the greatest
tensile strength is developed.
The machine, on account of the severity of the operation, wears rapidly and is
liable to breakage, and the necessary adjustment of the dies, as the reduction of the
wire proceeds, is difficult to secure in a satisfactory manner.
According to the present invention the wire after being cut to the proper length,
is reduced between the ends very nearly (say within one or two thousandths of an
inch) to the desired diameter, this operation being performed by means of two
pairs of rolls, the axes of the second pair being at right angles to those of the first
pair. Any suitable mechanism may be used to feed the wire stock to the inachine
and to cut it off to the proper lengths.
In the machine hereinafter explained in detail, and which exhibits the best
embodiment of the invention now known to me, the first pair of rolls flatten the
wire between its ends, while elongating it, and the second pair restore the circular

page_text: form while further elongating it. The object of this construction will be evident
upon brief explanation. If rolls with a circular pass were brought to act on the
wire at an intermediate point, they would cut into the wire, besides raising two
large fins, but by first flattening the portion to be reduced, and then acting on the
edges of the flattened portion with rolls at right-angles to the first pair, the desired
result is effected.
Special features of construction, hereafter explained, are adopted, whereby the
action of the rolls is exerted only upon the intermediate portion of the wire,
whereby the wire is brought to the proper length, whereby the rolls, while turning
continuously, operate without mutual interference, and whereby the machine may
be adjusted to produce different sizes of spokes. Other features of novelty in this
portion of the machine will be hereinafter explained.
The wire passing from the second pair of rolls is fed by the latter to the swaging
device, the relations of these mechanisms being such that the rolls deliver the wire
in just the proper position for the beginning of the swaging action. The forward
end of the wire is grasped by a gripping device (which may be in the form of a
chuck, or set of spring jaws or of other suitable form) and thereby carried at the
proper rate of speed between the:swaging dies.
The wire, during, this part of its travel, is rapidly rotated. The result is the
same as when the dies are rotated, but in the preferred form of machine it is more
convenient to rotate the device which feeds the wire..
When the wire is delivered from the swaging device it is completely finished
over the surface of the reduced portion and over the surface of the shoulders
joining such reduced portion to the enlarged ends. It only remains to finish the
ends, which require separate operations not forming part of this invention.
It is obvious that the speed of movement of the wire through the swaging device
is very many times greater than the inaximum speed possible when the reduction is
effected by swaging. As the rolls operate simultaneously with the swaging device,
no additional time is consumed by them.
In addition to the great economy and increased product thus effected, the
finished spokes are believed to have greater tensile strength than those heretofore
made, the working or forging under the blows of the dies not being excessive.
The invention embraces not only the combinations of the elements constituting
the complete organized machine, but also special improvements, which may be
advantageously used in machines devised for making articles which require to have
a reduced diameter for a portion of their length other than wheel-spokes. In the
swaging device as hereinafter described in detail, one of the dies is rapidly
vibrated, while the other die is relatively stationary during the swaging operation.
The latter die, however, is provided with automatic regulating or adjusting devices,
for controlling its position with respect to the vibratory die. Thus, in making
spokes the space between the dies is at first a little wider than the diameter of the
enlarged ends of the spokes, then it gradually diminishes to the diameter desired
for the intermediate portion of the spoke, remaining at that size until near the end
of such portion, when it again enlarges to the diameter of the end of the spoke.
This adjusting device may be, and preferably is, in the form of a cam properly
constructed to set the adjustable die at its respective working positions with
reference to the different portions of the stock on which it acts.
The action of the vibratory die is preferably effected by a cam of special
construction, comprising a disc shaped support provided with a series of rollers
near the periphery and projecting beyond the same a proper distance to give
to the die a blow of the desired force. Special means are provided to take the
shock of the blow off the shaft of the die, and other improvements are embraced
in this part of the invention which will be explained hereafter.
The invention includes certain other specific improvements in parts, details,
and combinations, which can be most conveniently described in connection with
the accompanying drawings which illustrate a spoke-making machine constructed
in accordance with the invention in the form best known to me.

A represents a pair of rolls on vertical axes, to which rolls the wire stock,
severed into pieces of proper lengths, is fed continuously by any suitable feed
mechanism which it has not been considered necessary to illustrate as it forms no
part of this invention. A' represents. cutter, of any ordinary or suitable
description for severing the wire stock into proper lengths. It acts just as the
rolls A take hold of the wire.
Rolls A have plain or smooth surfaces, so that they simply flatten the wire in
passing between them. Portions of the surfaces of the rolls A are cut away, as
shown at a leaving acting surfaces extending part way (in this case nearly half
way) around the rolls, to a distance corresponding to the length of the portion of
the wire to be reduced. When the cut-away portions of the rolls A are opposite
each other a blank or length of the wire b is fed in and left in the position shown
in Figure 1, with the forward end projecting a proper distance beyond the axes of
the rolls. The rolls rotating in the direction of the arrows the blank is seized and
drawn in between the acting surfaces of the rolls which then besides flattening the
wire feed it into the second set. of rolls B, which are so positioned, and timed in
their operation, that their acting surfaces come into operation just after the rolls A
release the wire.
The rolls A are driven from the main shaft A' by means of bevel gears a¹ a²,
cross-shaft A3 and bevel gears a³ a, the latter being on the shaft of one of the
rolls A. The construction and operation of the driving mechanism are, of course,
matters of minor importance.
The distance between the primary rolls A, and secondary rolls B must be such
that the wire, when released by the rolls A, will be advanced to such a point that
the beginning of the flattened portion will be just in the bite of the rolls B. In
order to adapt the machine to making spokes of different lengths the rolls B
with their support are adjustable on the bed of the machine towards and from
rolls A.
To this end, the casting or frame B' supporting the rolls B is secured to the
bed plate K of the machine by means of bolts & which pass through a slot b³ in
the said bed-plate.
Between the rolls A and the rolls B is a small spring friction guide c to keep
the wire from twisting and to insure its being delivered to the rolls B with its
flat faces in a vertical plane.
It is very desirable that the same rolls should be available for use in making
spokes of different lengths, as the expense of providing a separate pair of rolls for

page_text: each size of spoke would be very great. To this end we have devised means
whereby the acting surfaces of the rolls (A and B) may be increased or diminished
in length. This feature of the invention is illustrated in Figures 1 and 3.
Each roll is provided with an extension block a set into a dove-tailed socket at
one end of the acting surface of the roll, and having a portion forming a continuation
of the acting surface. The length of the acting surface may therefore be varied
by using different blocks, a number of which may be furnished for each roll, the
several blocks, of course, having extension acting surfaces of various lengths.
The wire b after passing through the rolls A is somewhat elongated and brought
to the shape shown in Figure 15. The rolls B are fluted or grooved as shown and
act upon the edges of the flattened portion of the wire the elongation thereof being
mainly effected by the said rolls.
In addition to the adjustment of the length of acting surface of the rolls, already
explained, several other adjustments are provided. One of these adjustments has
for its object to bring the grooves in one roll exactly opposite to or in register with
those of the other roll, this adjustment having also for its object to enable the same
rolls to be used to produce spokes of different diameters.
As shown in Figure 2, the rolls B are mounted each on a shaft B' journalled in
bearings in standards B2 B. The shaft of the lower roll is driven by bevel
gears T, T (Figure 1) from the main shaft A2, and drives the upper roll shaft by
means of gears 62 63 (Figure 2).
The adjustment for effecting the exact alignment or register of the grooves, in
the rolls B is provided for by forming screw threads 6 6 respectively, on the upper
shaft B at the sides of standard B2. These threads are engaged by corresponding
threads in collars 66 67 which are transversely split at one side and connected by
screws (see Figure 13) whereby the collars may be tightly fixed on the shaft.
By loosening the screw 8 and turning the collars, the shaft may be given a limited.
longitudinal adjustment. A collar similar to collars 66 67 is arranged on lower
shaft B' to take up wear.
To take up wear between the peripheral surfaces of the rolls B the bearing of
the lower shaft B' in the standard B³ rests upon a wedge-shaped block 610 which
may be adjusted to raise said bearing by a bolt 6" and nuts 61. This adjustment
is, of course, very slight.
The rolls B are, as shown, bolted on the ends of their respective shafts,
two washers d being interposed between each roll and an annular shoulder or
abutment on the shaft, the rolls being secured by nuts d¹. Each roll has five grooves
or flutings, which, though of different sizes, are the same distance apart from centre
to centre. The washers d are each of a thickness equal to this distance. The
centre groove is that which is in the line of action. By removing one washer d
the adjacent groove on one side can be brought to the working position, and by
removing the roll from the shaft and replacing it with the outer face inwards, the
corresponding groove on the other side of the central groove cau be brought in to
working position. Removal of both washers d permits in like manner either of the
outside grooves to be used. By using two washers au adjustment to any one of the
several grooves may be obtained, or if there are but three grooves the adjustment
may be effected by a single washer.
Between the rolls B and the swaging device is another small friction guide aº,
by which the partly finished spoke is supported until seized by a clutch hereafter
described.
The rolls B are so arranged with reference to the swaging device, as to deliver
the wire between the swaging dies, while the latter are open, with the enlarged
forward end projecting beyond the dies. In this position a feeding device seizes
the forward end of the wire, drawing it between the dies, while rapidly turning it,
until the enlarged rear end of the wire reaches the dies, at which moment the dies
separate to allow this end of the spoke to pass.
Leaving the feed mechanism for the moment, the construction and operation of
the swaging mechanism will next be explained.

page_text: The die g (Figures 7 and 8) is herein termed the vibratory die, and the die h
the adjustable or anvil die. These dies are carried respectively by slides g¹ h
supported so as to move freely in ways of the frame K. The die g receives its rapid
vibratory movement from a rotating disc or wheel G Figures 1, 4, 5 and 6 provided
with a series of cam projections g in the form of rollers set into sockets in the
wheel or support G (see Figure 14), and successively striking against the roller g
in the end of slide g'.
The wheel G has an annular web of reduced thickness at its periphery and
through this web are bored the holes for the rollers g2, which are placed loosely
therein. They are retained in place by holding rings g, one on each side (see
Figures 5, 6 and 14). The rollers and g both tura in striking thereby constantly
presenting fresh surfaces, and reducing friction. To reduce as far as possible,
vibrations of the shaft of the wheel G there is placed on the opposite side of the
wheel from the die a bearing block or support G2 which is concaved to correspond
to the convexity of the wheel, over which concave surface the rollers g³ travel.
The block G is held in a socket in the frame by means of screw 9", and it may be
adjusted by means of the said screw and set screws g'. The slide h' is also pro-
vided with a roller 2 on its end to receive the action of a cam H the function of
which cam is to set the die h at its different working positions during the process"
of swaging a spoke. Figure 5 shows the die in the position it occupies while the
body of the shank is being swaged. When the cam has made nearly half a revolu-
tion from that position the incline on the cam H permits the die h to recede
thereby separating the dies so that the enlarged rear end of the spoke can pass
from between them, and 'the enlarged forward end of the next spoke enter.
incline on the cam now comes into action, and gradually closes the die h upon
the die g, until they are at the right distance apart to form the bo.ly of the spoke.
A spoke is finished at each revolution of cain H, which turns at the saine axial
speed as the rollers A and B.
An
Figures 7, 8 and 9 clearly show how the dies are set in their slides or supports.
The end of each slide is provided with a rectangular socket, of the proper width
and height to receive the die. Behind the die g in a recess in the slide g' is a
backing plate 9 of hardened steel to receive the thrust of the die, the latter being
loose in its socket. The die is provided with an adjustment to take up wear, and
to compensate for regrinding the dies. To this end the back-plate h³ is wedge-
shaped, and the recess in which it fits is also inclined. The plate has a cross-
piece at the top through which passes an adjusting screw h, which screw engages
in a threaded socket in the slide 1, the wedge shaped plate h being firmly clamped
in its adjusted position by a set-screw hs, which screws into the cross-piece he and
bears at its end against the top of said slide.
The swaging device as a whole is supported on the frame K which rests on the
bed K' of the machine and is provided with a groove engaging a rib or spline k¹ on
the bed, whereby the swaging device can be set closer, to or farther from the rolls B,
according to the length of spoke that is being made.
The feed inechanism for carrying the wire through the dies comprises a slide L
(Figures 1 and 4) moving in ways in the frame K, the said slide making a complete
reciprocation back and forth to each revolution of the main shaft. The slide L
receives its movement through a long arm or lever L' from a cam L' on the main
shaft A, the arm L' being fulcrumed at L³. The slide L carries a hollow
spindle M, supported in bearings M2 on the said slide, and rotated by means of a
pulley M. At the forward end of the spindle inside the forward bearing M2 is a
head M having a flaring opening. Within the hollow spindle M is a rod m having
on its forward end split spring jaws n, forming a chuck, for grasping the end of
the wire spoke. In operation, as the slide advances the jaws are open. When the
slide comes to rest, the spoke having entered the jaws, the latter are drawn into
the hollow head, the bevel of the latter causing the jaws to close firmly upon
the spoke. The slide then retracts, drawing the spoke through the dies, the

page_text: spindle M being in constant rotation.. When the slide reaches the limit of its rear-
ward motion the chuck rod is pushed forward, and the jaws springing open release
the spoke.
The devices for automatically opening and closing the chuck-jaws may be con-
structed in different ways. As shown in the drawings a rod n gives to the chuck
a slight motion sufficient to open and close the jaws. This rod. has two adjustable
stops o, o'. When the slide has advanced (as in Figure 1) the stop o! is in contact
with the end of a lever o, the other end of which engages in a camigroove o. At
this instant the lever o, actuated by the cam o pushes the rol n¹ to the rear,
thereby drawing in aud closing the jaws. When the slide. L has fully retracted. a
reverse movement is given to the rod n! by the lever o acting on the stop o.
Connection between the rod and chuck rod m is made in the following way.
The rod n' is attached to an arm n³, pivotted at n. to an upright on the slide L.
The arm 3 carries a yoke which embraces a collar which is loose and free to
slide on the spindle M.. A pin passes, through the chuck rod m and has a limited
movement lengthwise of the spindle in a slot therein, this movement being sufficient
for the opening and closing.of the chuck-jaws.
The arm n³ has a small lug n which is engaged by a spring-catch attachel
at one end to the bearing, M. When the rod n! has been pulled back, the catch n
engages the front side of the lug n', and prevents the chuck from moving out of
the head. When the rod n¹ is moved in the opposite direction the catch springs
onto the other side of the lug and holds the chuck jaws open. In order that the
backward movement of the rod ' may not inove the slide, the latter is locked in
position when the lever o2 acts on the stop o'. This is effected by a locking armr
which, at the proper moment, drops into a notch in a block on the rear bearing M³
(Figure 1). The other end of arm r carries a pin or roller which enters a
groove of proper shape in a cam R on the shaft R', which carries the cam o.
The cam R is so constructed as to move the locking arm into engagement with the
lock at the proper moment.
It has been stated that the auvil die h can be adjusted to compensate for wear
on both dies. Such adjustment necessitates a corresponding adjustment of the
feed devices to keep the axis of the chuck always in line with the axis of the dies.
To this end the slideway K2, upon which the slide L works, can be adjusted
slightly on the base K. The said slideway is attached to the base K by a pin qand
screws q, the latter passing through slots in the slideway. By loosening the screws
the desired adjustment can be effected, the slideway turning on the pin q as a pivot
When properly adjusted screws q³, one on each side of the slideway, are brought to.
bear on the sides thereof, and hold it firmly in position (see Figure 4). The
adjustment of the throw of slide L is provided for by making the fulcrum L of the
arm L' adjustable lengthwise of the said arm, which arm is slotted or grooved; and
in the slot or groove is a square block L perforated to receive the journal pin L.
This pin is journalled in a support S, and may be set nearer to or farther from the
cam L³, as desired. The support S is itself adjustable in a liné parallel to the main
shaft, it being secured to the bed by means of bolts s passing through slots in the
support S, or in the bed, or in both.
The connections and gearing for driving the various parts of the machine are
clearly shown on the drawings.
The gearing for driving the rolls A and B has already been explained. The
shaft R which carries the cams. H, R. and o, is driven from the shaft A? by bevel-
gears T2 T3, cross-shaft T and bevel gears T5 T. All the gears on the main
shaft A are adjustable lengthwise thereof. The shaft G which carries the cam G
is driven by a belt and pulley. G.
It will be seen that three revolutions of the main, shaft carries a blank entirely
through the machine, and completes it. At the first revolution it passes through
the rolls A, at the second through the rolls B, and at the third through the
swaging device. Consequently at each complete revolution a finished spoke will be
delivered.
