PROVISIONAL. SPECIFICATION.
I, JOSEPH SHELTON, of 16, Pool Street, Wolverhampton, in the County of
Stafford, Machinist, do hereby declare the nature of my invention for IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR STRAIGHTENING, CUTTING OFF, AND
HEADING, LENGTHS OF WIRE, SPECIALLY APPLICABLE FOR THE MANUFACTURE OF
THE METALLIC SPOKES OF VELOCIPEDE WHEELS AND SIMILAR WHEELS, to be as
follows:-
The mechanism, constructed according to this invention, for straightening and
cutting off the lengths of wire is, preferably, constructed as a separate machine
from that for heading the lengths of wire after the same are cut off.
I will first describe that part of the mechanism for straightening and cutting off
the lengths of wire. The coil of wire from which the lengths are to be cut off is
carried on a reel at the front of the machine. A series of vertical and horizontal
rollers are carried at the front of the machine and arranged to be adjustable in
relation to one another so as to take out from the wire any curve or bend therein.
Two dies having their faces grooved for the passage of the wire, are carried behind
the rollers. One of these dies is pressed towards the other by means of a weighted
lever, or a spring, and thus friction is put upon the wire on its passage between
the dies. A shearing die is carried within a block capable of longitudinal motion
upon a slide running backwards from the friction dies, and a shear arm is
fulcrumed to the back face of this block and has a cutting edge working against
the back face of the shearing die so that, if the shear arm is raised, any length of
wire projecting through the back face of this die is cut off. When not pushed
forwards as hereinafter described, this block is kept in position backwards against
a stop by means of springs or a weighted lever. At the back of the last mentioned
block, and carried upon the same slide, is a second sliding block upon which is
mounted a gripping lever. The forward end of this lever has a set-pin there-
through forming a top gripping die the nose of which is marked across with teeth
and comes opposite to a grooved bottom gripping die carried upon the block. The
back end of the lever is pressed down, when such lever is not gripping, by means
of a spring so as to keep the front end raised and the top gripping die well above
d

page_text: mule
bottom die so as to allow room for the wire to enter easily between such
dies. Parallel with the slide before-mentioned is a second slide or bar, and upon
this slide is carried a sleeve. An arm projects from this sleeve over the second-
mentioned sliding block upon which it is held down by means of a pin, passing
through a hole in the arm slotted lengthways of the machine and fixed within the
block. A stud projects from the other side of the sleeve from which a connecting-
rod passes to a crank arm rotating upon a cross shaft at the back of the machine.
A cam is fixed upon the cross shaft, aforesaid, and during part of its rotation
presses forwards a rod carrying an inclined plane which comes in contact with a
similarly shaped end of a lever which bears under the shear arm, aforesaid, to raise
such arm.
The rod is held back in its normal position by means of a spring or
weighted lever in which case the lever and shear arm are in their downward
position.
In order to work the machine, the wire to be cut into lengths is fed between the
straightening rollers, through the friction dies and shearing die to the back face of
such shearing die, and the gripping block is pushed forwards against the shearing
block carrying such block forwards and leaving the end of the wire projecting
somewhat beyond its back face. The machine is then set in motion by driving the
cross-shaft at the back end thereof, either by hand, or other motive power and
with suitable gearing as may be necessary. The crank arm is in position, to draw
forwards the sleeve, aforesaid, and consequently the arm projecting therefrom, and
tlie slotted hole through such latter arm permits of it travelling backwards upon
the gripping block. The back end of the part of the arm upon the gripping block is
formed as an inclined plane to act against a correspondingly shaped part on the
lower side of the back end of the gripping lever, and thus as the arm is pulled
backwards upon the block the back end of the lever is raised and the top gripping
die is brought down upon the end of the wire projecting through the shearing die,
tightly gripping.it between itself and the bottom gripping die. As the back end of
the lever cannot be further raised, the continued backward motion of the arm carries
back with it the gripping block also.and draws back the wire through the shearing
die, friction dies, and the straightening rollers, the shearing block itself, however,
returning to its backward position against a stop. As the crank-arm, aforesaid;
commences its return stroke, the arm on the sleeve begins to move.forwards upon
the gripping block and the back end of the gripping lever is pressed down
by its spring, thus raising the top gripping die and, releasing the end of
the wire.
As soon as. this last operation has taken place, the cam. upon
the cross-shaft, aforesaid, presses. forwards the rod carrying the inclined plane
and raises the shear arm which, cuts off the length of wire projecting through
the, shearing die, aforesaid. As the cam passes out of action with the rod,
the latter returns to its backward position and the shear arm falls again into its
former position, this action of the arm being facilitated, if necessary, by means of a
weight or spring. A set-pin or other adjustable stop is fixed upon the gripping
block and as the sleeve, aforesaid, is continued to be moved forwards the arm
thereon comes against such stop, and thus carries such gripping block forwards
again. The gripping block is thus brought against the shearing block, and this
forward motion of the gripping block continues until the shearing block is pusbed
sufficiently far to allow the gripping dies to come into position with the end of the
wire between them which is left projecting after the movement of the shearing
block, the friction' dies securely preventing, the, wire from being moved as the shear
block is pushed forwards. As the sleeve, aforesaid, is pulled backwards again, in the
manner already described, the projecting end of the wire is gripped and the wire is
pulled through the machine as before, the cutting-off being effected also in the
manner before-described. One revolution of the cross-shaft has thus the effect of
straightening, drawing through, and cutting off, one length of wire, and placing the
parts in position to draw the wire through again. A slanting guide is placed
behind the gripping tools so as to throw the length of wire sideways during the
forward or return stroke of the gripping block.

page_text: I will now describe that part of the mechanism for heading the lengths of wire
cut off by the mechanism above described. A heading die is carried upon the end
of a bolt working in a suitable guide and actuated by means of a connecting-rod
driven from a crank upon a cross-shaft at the back of the machine framing. This
connecting rod is in two parts connected together by means of a lap-joint and pins
or bolts. The holes for such pins or bolts are slotted through one of the laps to
allow of any necessary adjustment in the length of the rod. The outer end of each
lap of the joint faces a shoulder at the root of its opposite lap, and a wedge or liner
may be driven or inserted between such faces and shoulders to relieve the strain
upon the pins. A pair of gripping dies are carried in a box at the front of the
machine and just in front of the heading die. These dies are properly grooved on
their faces to receive and grip the wire between them; and the faces of these dies
which are towards the heading dies have counter-sunk, parts surrounding the
grooves to shape the inner surface of the heads to be formed. The four side
faces and the two end faces of each of these dies are grooved and counter-sunk,
respectively, so that as one face is worn another face may be brought into use.
The upper of these dies is kept raised from the other die, when in its normal
position, by means of a spring which presses a wedge in between the two dies on
one side thereof; and this upper die is forced down to grip the wire to be headed,
by means of a lever which is actuated by a cam upon the cross-shaft aforesaid.
This cam is preferably constructed as a disc-crank for working the heading tool, the
crank pin for such purpose being cast solid with or otherwise fixed to the cam.
The pressure of the lever is conveyed to the top die by means of a pin or bolt
passing through the top of the box, aforesaid. The side edges of the gripping dies
are rounded over to facilitate the action of the wedge forced in between them to
raise the top diè, and also to allow of such wedge being forced back against the
spring as the top die is forced down to grip the wire. A grooved guide is fixed at
the front of the machine by which to guide the end of the wire properly between
the gripping dies. A gauge, against which the end of the wire is pushed, is held
by means of a spring in the proper position at the back of the gripping dies until
the wire is gripped tightly, and as the heading tool advances it acts against an
inclined part of the gauge and pushes such gauge clear until the wire has been
headed and the heading tool is partially drawn back, when the gauge springs in
again as before.
1
The operation of. the machine is as follows:-The end of the wire to be headed
is pushed along the guide and against the gauge. The upper gripping die is forced
down, pushing outwards the wedge between itself and the bottom die, and tightly
holds the wire. The heading tool advancing pushes outwards the gauge and beads
the wire. The heading die is then drawn back, the gauge returning to its former
position, and the gripping lever rises and allows the wedge to be forced in by its
spring thus raising the top gripping die and releasing the wire which is now
removed with the head completely formed thereon. A second length of wire is
then fed in and so on as before.

page_text: I, JOSEPH SHELTON, of Kingston House, Sedgley Street, Wolverhampton in the
County of Stafford, Machinist (formerly of 16 Pool Street, Wolverhampton,
aforesaid) do hereby declare the nature of my invention for IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR STRAIGHTENING, CUTTING OFF, AND HEADING
LENGTHS OF WIRE, SPECIALLY APPLICABLE FOR THE MANUFACTURE OF THE
METALLIC SPOKES OF VELOCIPEDE WHEELS AND SIMILAR WHEELS and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the accompanying
drawings:
The mechanism, constructed according to this invention, for straightening and
cutting off the lengths of wire, is, preferably, constructed as a separate machine
from that for heading the lengths of wire after the same are cut off.
I will first describe that part of the mechanism for straightening and cutting off
the lengths of wire, and in doing so will refer to the drawings on sheet 1 herewith,
of which figure 1 is a side elevation of such mechanism and figure 2 a plan thereof.
The coil of wire from which the lengths are to be cut off is carried on a reel at the
front of the machine so that the wire therefrom may enter the machine through the
tube a, curved on plan approximately to the curve of the coiled wire so as to give
such wire a lead in. This reel is not shewn, but will be readily understood. It is
simply placed so as to turn upon its axis and allow the wire to be unwound as it
is drawn in by the machine. A A etc. are legs supporting the framing composed of
the bars B B and plates C, D D and E. bb and b¹ are vertical grooved rollers carried
upon short standards fixed to a plate F which is itself fixed to the bars B B so as to
be adjustable therealong. The standards supporting the rollers are adjustable as to
height by means of the lock nuts thereon, as shewn in figure 1, and the roller b¹ is
adjustable also by means of the slot c and set screw d. c¹ is a screwed lever to lock
the set pin d. The wire is passed over the rollers bb and under the roller b¹ so
as to take out any kink or curve vertically, the roller b¹ being set at a level in
relation to the rollers b b as required for this purpose. e e and el el are corre-
sponding rollers to those already described but are placed in a horizontal plane.
Each of the rollers e e and the pair of rollers e¹ el are capable of a vertical adjust-
ment by means of lock nuts on the standards supporting them, as shewn, and are
capable also of a transverse adjustment by means of the slots a¹ a¹ a', screwed
spindles c¹ cc' through slides or blocks d" which carry the studs supporting the
rollers and handles d' d' d. One of the standards supporting these last described
rollers is shewn at figure 3, which is a transverse section on line x of figure 1.
fff is the wire and is shewn as if straight where passing between the rollers,
though it would in reality be curved, according to the relative position in which it
may be found necessary to place the rollers for the purpose of taking out kinks or
curves in the wire. From the last set of rollers the wire passes between a pair of
friction dies f¹¹ carried in a block G fixed to the plate Ċ which is itself fixed to
the plate D D as are also the two bars B B. These dies f¹ f¹ are grooved on their
inner faces to more effectually grip and guide the wire, and pressure is put upon
them by means of the lever g, having a weight h hung on the end thereof, and
pin g¹, which latter passes down through a hole in the top of the block G and bears
upon the top of the upper die. From these dies the wire passes through a solid

page_text: This shaing
shearing die h¹ carried in a projecting part H of a sliding block J.
block J is carried upon a square bar K fixed to a carrying block L at its forward
end, and to the plate E at its back end by means of the pin q. A front elevation
of this block is shewn by figure 4, which is a vertical section on line xx¹ of
figure 1. i is a shear arın having a steel cutting part or blade at ¹. This lever is
fulcrumed to the block J at j¹ so as to be carried entirely by such block, and is held
in its downward position by a weight j hung on its outer end. M M are springs
connected at one end to the arms N1 N1 projecting from the block J and to a pair
of legs not shewn (in consequence of the framing of the machine being broken in
its middle for convenience of illustration) at their other ends, so as to pull the
block J against a stop k, which acts also as a guide to the outer face of the shear
arm i. N is a second sliding block (hereinafter called the gripping block) upon
the bar K, and O is a gripping lever mounted thereon. k¹ is a set-pin through the
forward end of the gripping lever forming a top gripping die the nose of which is
marked across with teeth and comes opposite to a grooved bottom gripping die
carried upon the block N. When the lever O is not gripping the weight of its back
end balances up the front end so as to keep such end raised and the top gripping
die well above the bottom die, so as to allow room for the wire to enter easily
between the dies. P is a second slide or bar carried in blocks n n¹ upon the
framing of the machine, and Q is a sleeve formed to slide thereon. R is an arm
projecting from the sleeve Q across the top face of the block N and is held down to
such block.by means of a pin passing through a hole in the arm slotted lengthways
of the machine and fixed within the block S is a stud projecting from the sleeve Q
from which a connecting rod T passes to a crank arm U rotating upon a cross
shaft V at the back of the machine. A cam W is fixed to a disc X upon the cross
shaft, aforesaid, and during part of its rotation presses forwards a rod Y carrying a
curved or inclined lifter Z which raises the end of a lever A¹, bearing under
the shear arm. i, to raise such arm. The end of the rod Y is curved as shewn to
allow of an easy action of the cam W which rotates in the direction of the arrow
adjacent to it. The rod Y is carried in suitable guides one of which is shewn
as an open-topped guide at F¹, and is held back in its normal position, with its
curved end almost touching the periphery of the disc X, by means of the spring B',
in which case the lever A¹ and shear arm i are in their downward position. In
order to prevent the curved end of the rod Y from banging against the periphery.
of the disc a cross piece or stop m¹ is fixed to the bar and forins a stop thereto
backwards against the front of the guide F¹.
In order to work the machine, the wire to be straightened and cut into lengths
is fed between the straightening rollers, through the friction dies f' f' and shearing
die h', to the back face of such shearing die. The machine is then set in motion
by driving the cross-shaft at the back end thereof, through the medium of a fast
pulley C¹, pinion D¹ and spur wheel E¹, or the machine may be worked by hand
if desired. The gripping block N is thus pushed forwards against the shearing
block J, carrying such block forwards and leaving the end of the wire projecting
somewhat beyond its back face, as the wire, being held in the friction dies f¹ f' is
prevented from being pushed back with the block J. The crank arm U is now in
position to draw forwards the sleeve Q, and consequently the arm R projecting
therefrom, and the slotted hole through such arm permits of the sleeve travelling
backwards upon the gripping block for a short distance. The back end of this arm
is curved over as shewn at o to act against a friction roller o¹ in the end of the
gripping lever O, and thus, as the arm R is pulled backwards upon the block, the
back end of the lever O is raised and the top gripping die is brought down upon
the end of the wire projecting through the shearing die ', tightly gripping it
between itself and the bottom gripping die . As the back end of the lever O
cannot be further raised, the continued backward motion of the arm R carries back.
with it the gripping block also and draws back the wire through the shearing die h¹,
friction dies f f and the straightening rollers, the shearing block J; however,

page_text: returning to its backward position against the stop k before the wire can be drawn
through it. As the crank arm U commences its return stroke (after drawing the
block N to its furthest extremity backwards) the arm R begins to move forwards
upon the block N, and the back end of the gripping lever O, falling by its own
weight, raises the top gripping die and releases the end of the wire. As soon as
this last-described operation has taken place, the cam W presses forwards the rod Y
and the curved lifting block Z and raises the lever. A¹ and the shear armi, thus
cutting off the length of wire projecting through the shearing die h¹. As the
cam W passes out of action with the rod Y, the latter is brought to its backward
position by the spring B¹, and the shear arm i falls again into its former position.
As the arm R continues to move 'forwards upon the block N, the end of the slotted
hole therethrough comes against the pin , or the arm itself comes against a stop
on the block: N, and thus, by the continued forward motion of the arm R, the
gripping block N is again brought against the shearing block J, and this forward
motion of the block N continues until the block.J is pushed sufficiently far to allow
the gripping dies ; to come into position with the end of the wire between
them which is left projecting after. the movement of the block J. As the sleeve Q
is pulled backwards again, in the manner already described, the projecting end of
the wire is: gripped and the wire is pulled through the machine as before, the
cutting off being effected also in the manner before described. One revolution of
the cross-shaft V has thus the effect of straightening, drawing through, and cutting
off, one length of wire and placing the parts in position to draw the wire through
again.
The arm N projecting from one side of the block J is provided at its outer
extremity with a set pin f the end of which is formed flat and bears upon the
guard or slide gl¹ so as to act against the tendency which the shear arm i has to
twist the block J on the bar K as it shears the wire.
'
The crank arm U is provided with a number of holes, as shewn, so that the
length of stroke of the block N may be varied to suit the lengths of wire required
to be cut off, and the connecting rod is also made adjustable as to length, as shewn,
(by being formed in two parts bolted together through slotted holes in oue part)
in order that it may be lengthened as the stroke of the block N is shortened, as
such, block must always be moved to the same position at the forward end of its
stroke.
The machine may be driven at any convenient speed, but I have found that a
speed of from twenty to thirty revolutions per minute of the cross shaft V carrying
the crank arm answers very well.
$:
Figures 5 and 6 are respectively a plan and side elevation of an arrangement for
throwing off a length of wire after it is cut off. Only sufficient of the machine is
shewn in these two views to make the illustration clear, and any parts occurring on
these views corresponding to parts shewn on figures 1 and 2 are correspondingly
-lettered. G is a bar carried upon a fulcrum pin H¹ and pulled inwards by means
of a spring connected to the top of a rod t. The bar G₁ has a nose s¹ which is
niched or grooved to.bear around one side of the wire f. Jis an angle-piece carried
upon a fulcrum u¹ and drawn inwards by means of a spring v. The angle-piece J1
has a nose w niched or grooved to bear around one side of the wire, and has also
a guard running across the machine in an upward direction to prevent the cut-off
length of wire from flying up. Immediately the end of the wire is released from
the gripping, dies the angle-piece J₁ springs. inwards and forces such end of wire
sideways, and immediately a length of wire is cut off the lever G¹ springs inwards
and throws the wire sideways clear of the machine. As the block N travels towards
the block J.the side a¹¹ of the angle-piece J comes in contact with the curve c¹¹ of
the bar G, and travelling along inside the curved and inclined part of, the bar G₁
forces such bar outwards.. During the continued movement of the block N towards
the block Jithe side d of a projection 6 comes against the outer curved side of a
.

page_text: part e“ nxed to the projection of the block J, and by this means both the bar
and the angle-piece J' are moved outwards clear of the wire which projects through
the block J as such block is moved backwards, thus enabling the gripping dies
to take hold of the wire. As the wire is drawn back the bar G¹ and angle-piece J¹
are drawn back by their springs with their noses around the wire.
I will now describe that part of the mechanism for heading the lengths of wire
cut off by the mechanism above described, and in doing so will refer to the drawings
upon sheets 2 and 3 herewith, of which figure 7 is an elevation and figure 8 a plan
of the mechanism for heading the lengths of wire. Figure 9 is a section on line xx
of figure 7, and figure 10 a.sectional plan on line y y of figure 7. A is a strong
frame or block carried upon legs or standards B B, and C is a cross-shaft driven
from a fast pulley D through the medium of the shaft H, the pinion E and spur
wheel F. G is a fly-wheel on the shaft H. J is a cam formed upon a disc L carried
upon the shaft C, and the outer curve a of this cam is struck from the centre of the
shaft. K is a stud preferably cast solid with the disc. M is the connecting-rod
connecting the stud K with a bolt N. This rod M has an eye at one end to fit
around the stud K, and is connected to the back end of the bolt. N by means of
plates bb and pins cc, the back end of the bolt N bearing in the curved or hollowed
end of the connecting-rod M, as shewn by dotted lines figure 7, so as to receive the
direct thrust of the rod. The bolt N slides within a guide block O formed with or
fixed to the block or frame A. d is a heading die fixed in the front end of the
bolt N, and ee are gripping dies carried in a box or opening formed therefor in the
block A and just in front of the heading die. These dies e e are grooved on their
abutting faces to receive and grip the wire between them; and the faces of these
dies which are towards the heading die are counter-sunk, as shewn at f, to shape
the inner surface of the heads to be formed. A space is preferably left in the box
under the lower die into which a liner of the required thickness is inserted to keep
the die at its proper level. gg are plates bolted to the face of the block A by
means of bolts h h etc., so as to keep the gripping dies in position when at work,
and be removable for removing and replacing them. The upper of these dies is
kept raised from the lower, when in its normal position, by means of the spring i
pressing against a bar j having a wedge-shaped end k which enters between the two
dies at one side thereof, and this upper die is forced down to clip the wire to be
headed by means of a lever P, having its fulcrum pin Q carried between snugs R R
on the block A, and actuated by means of the cam J bearing underneath a friction
roller S in a jaw forming the back end of the lever. The front end of this lever
presses a vertical bolt upon the top die e when the cam J raises the back end of
the lever; and as the back end of the lever falls, by its own weight, as the cam
passes away therefrom, the front end of the lever rises and the wedge k forces up
the top die e and vertical bolt 7. As the top die e is forced down it forces back the
wedge k against the pressure of the spring i. The side edges of the dies e e are
rounded over to facilitate the action of the wedge k in forcing up the die and the
re-action of the die in forcing back the wedge. T is a grooved guide plate fixed to
the block A by means of the bracket U, and acts to guide the end of the wire m
properly between the dies e e. o is a flat piece of metal carried on the end of a
spring n' (shewn by dotted lines only figure 10) fixed to the part O. When the
bolt N is pulled back from the position shewn the part o springs inwards with its
nose against the block A, and acts as a gauge in front of the gripping dies e e so as
to fix the distance to which a wire is to be pushed through such dies to allow 'of
sufficient metal projecting in front of such dies for the formation of a head. p is a'
curved projection on the spring n, and as the front end of the bolt advances it'
comes in contact with this projection p and forces the gauge o outwards, into the
position shewn, so as to be clear of the advancing heading die d.
The operation of the machine is as follows:-When the upper die e is raised and'
the heading die back from the face thereof, the end of the wire m to be headed is
pushed along the groove in the guide T and against the gauge o.
The upper'

page_text: gripping die e is forced down by means of the cam J, lever P, and bolt L, and grips
the wire between itself and the lower die, and is held in such position by the curved
part a of the cam J. The wedge-ended bolt j is forced outwards by the die as it
descends. The bolt N advancing pushes the gauge o clear of the heading die d,
and the continued, advancement of the bolt N causes the heading die d to press
upon the short length of wire projecting in front of the dies e e and thus form a
head at the end of the wire. The heading, die is then drawn back, the gauge o
returning to its former position, and the front end of the gripping lever P rises, as.
the cam J passes out of action with 'the roller S, and allows the wedge k to force
up the top die e and release the wire, which is now removed with the head
completely formed thereon. A second length of wire is then pushed in by hand,
and so on as before. It will be seen that the wire is tightly gripped between the.
dies ee whilst the head is being formed thereon.
The connecting-rod M is in two main parts, as shewn, and these are connected
together by means of a lap joint A' B', and pins a¹ a¹ etc; the holes for these pins
are slotted through one of the laps to allow of any necessary adjustment in the
length of the rod as the parts wear or as the length of the tools may be slightly
varied. The outer end of each lap A¹ B' of the joint faces a shoulder at the root of
its opposite lap, as shewn, and a wedge or liner may be driven or inserted between
such faces and shoulders to relieve the strain upon the pins.
The four side faces and the two end faces of the dies e e are preferably grooved
and counter sunk, respectively, so that as one face is worn another face may be
brought into use.
