Improvements in Machinery for the Shaping or Bending of
Metallic Wire Lengths and Rods into Various Forms for
Various Purposes.
We, GEORGE SALTER of High Street West Bromwich in the County of
Stafford Manufacturer, and JOHN WALKER of Overend Street, West Bromwich
aforesaid, Manager of Works, do hereby declare the nature of this invention to
be as follows:-
This invention relates to improvements in machinery, for the shaping or
bending of metallic wire or rod lengths, into various forms for various purposes,
such for example as the skeleton base framing of a velocipede saddle, upon
which the seat framing is supported by pillar or other coiled springs interposed
between them; the framing of the seat of a velocipede, to wit, the skeleton rods
which pass immediately under the said seat, and to the front of which, the top ends
of pillar coiled or other springs are connected; the springs of lock work, consisting
of a loop at the return end of two parallel or obliquely directed arms, adapted to
impress themselves for producing a reaction, and further, all wire or rod portions of
cycle and other work or articles consisting of a frame, forked or bifurcated
character, with returned end, and with a loop at the said end.
In carrying out our invention in connection with the base framing of a velocipede
saddle seat, and which framing consists of two parallel or nearly parallel branches,
directed at about 2 inches apart, and with the fore and return end part curve
shouldered or gathered in, and provided with a loop, to pass around an half-inch or
other pin, whilst the terminal ends of the branches, are turned outwardly into loops,
for taking pins of a like size to the loop at the fore part, we take a wire or rod
length, sufficient to form the said article or framing, and place the same in position
between sets of the machine, which consists of a bed, channelled longitudinally up
its middle, wherein a dovetail-edged slide works, and with the top side coming flush
with the bed. This slide carries upon its said top side, a longitudinal block, with a
mose part of the inside shape of the shoulder part, and of the inside breadth of the
body part, of the article to be produced, and forward of the said nose, is a centrally
disposed and upright stud, at a distance equal to the length of the loop from its
extreme inside end, to the shoulder part aforesaid, and at the front of the said stud,
the wire or rod length, comes and takes a bearing against the front sides of rests,
curved or channelled inwardly to allow the wire length to lead off, when the same
is being pushed forwards at its unsupported middle.
The rear part of the machine, is provided with shaping jaws, working in unison,
and lineable with the slide, and adapted to close in upon the partly gathered in,
bent or returned end or fore part presented, and which said jaws consist of two
levers, pivoted near their fore parts, and with the tail ends being hooked inwardly,
against the insides of which a sliding plate impinges, on the said plate being struck
by a striker or kicker, carried at the extreme front of the slide.
The inside fronts of the levers, are formed alike unto hooks, with curved heads,
the shape of the outside front part of the article to be formed. These heads con-
stitute dies, with an open mouth or middle part, wherethrough the stud on the slide,
passes, before the kicker in front of it, strikes the sliding plate, which in its turn,
presses outwardly the rears of the levers, enclosing their fore parts upon the bent
or returned end of the article, hence the gathering in or contracting of the said end,
around the stud, and rearward of it.
Between the opposite sides of the block, and the rests, are spaces of the breadth
of the wire or rod length employed.

page_text: The slide is operated by an upright arm at the rear of it, being jointedly con-
nected to a link or coupling rod, which in turn is jointedly connected to a lever,
jointed and fulcrumed at its lower end, and at the top of which lever is an inertia
weight.
The machine, instead of being worked by a lever, may be worked by power or
other mechanical device.
OPERATION.
Assuming the jaws to be open, and the slide to be drawn back, with the stud
rearward of the rests, to the extent of the breadth of the wire or rod length, drop
the length between the sets, and against the rest, when the slide is moved forward,
and the front of the stud impinges against the inside middle part of the wire or rod,
which middle part being unsupported, the same is bent inwardly, and the branches
or ends directed in parallel directions, alike unto the arms of a staple, or the figure
of the letter U. The wire being thus carried forward by the stud, now impinges
upon the shaped inside fore parts of the jaws, which contracts or gathers in the
semi-circular front, by the stud forcing the metal through the gap between the jaws,
and against the shapings of them, and after this shaping has been performed, the
kicker upon the slide, strikes against the sliding plate, which on striking the ends
of the levers constituting the jaws, causes the said jaws to turn upon their joint
centres, and close the jaws upon the already gathered in or contracted front of the
article being shaped, hence the closing of the metal around the peg into a loop,
whilst at the same time perfecting the curved fore part rear of the loop.
The returning of the slides, brings the parts back into their normal positions,
and ejects the shaped frame as aforesaid, which is now curved or bowed, and the
terminal ends of the branches turned into outwardly directed loops or eyes.
The jaws, instead of being operated by the kicker, which stands above the top
face of the slide, may be operated by levers and connecting rods, worked by
the slide.
The application of our invention to the shaping of wire or rod lengths for the
production of other articles, differs in no essential respect from the shaping of a
base framing, as hereinbefore described, other than the disposition of the stud,
the shape of the nose, or both nose and sides, of the block, and the shapes of
the jaws.

Improvements in Machinery for the Shaping or Bending of
Metallic Wire Lengths and Rods into Various Forms for
Various Purposes.
We, GEORGE SALTER of High Street. West Bromwich, in the County of
Stafford, Manufacturer, and JOHN WALKER of Overend Street, West Bromwich
aforesaid 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:-
This invention relates to improvements in machinery for the shaping or bending
of metallic wire or rod lengths, into various forms for various purposes, such for
example as the skeleton base framings of velocipede saddles. The springs of lock
work, consisting of a loop at the return end of two parallel or obliquely directed
arms may be made by our said machine, and further, all wire or rod portions of

page_text: cycle and other work, or articles consisting of a frame, forked or bifurcated in
character may be made by the said machine.
In carrying out our invention in connection with the production of the base
framing of a velocipede saddle seat, we take a wire or rod length, sufficient to form
the said article or framing and place the same in position between sets of the
machine, consisting of a bed, channelled longitudinally up its middle, wherein a
dovetail-edged slide, works, and with the top side thereof coming flush with the
said bed. This slide carries upon its said top side a longitudinal shaping block,
with a nose part of the inside shape of the shoulder part, of the article to be
produced.
Carried by the said block and forward of the said nose, is a centrally disposed
and upright peg or stud, upon the front of which, the middle of the wire or rod
length comes, prior to the bending.
On the opposite sides of the channel, fixed shaping dies come, with a mouth
or entrance leading to the channel, and which mouth allows the wire length to
lead off, when the same is being pushed or carried forward at its unsupported
middle.
The rear part of the machine, is provided with shaping jaws, working in unison
and lineable with the slide, and adapted to close in upon the partly gathered in
bent or returned end or fore part presented, and which said jaws, consist of two
levers, pivoted near their fore parts and having tail ends, against which a sliding
plate impinges, on the same being struck by a striking nose at the extreme front of
the slide.
The inside fronts of the levers, are formed alike unto hooks, with curved heads,
of the shape of the outside front part of the article to be formed.
These heads constitute closing dies, with an open mouth or middle part, where-
through the stud, with the wire partly around it, passes, before, the striking nose
or kicker as aforesaid strikes the sliding plate.
After striking the rears of the levers, the fore parts of them, close upon the wire
or rod, and form the neck.
Between the shaping block and fixed dies spaces of the breadth of the wire or
rod come.
The slide is operated by an upright arm at the rear of it, being jointedly con-
nected to a link or coupling rod, which in turn, is jointedly connected to a lever,
jointed and fulcrummed at its lower end, and at the top of which lever, may be an
inertia weight.
The machine instead of being worked by a lever, may be worked by power, or
other mechanical device.
Figure 1 of the accompanying drawings, represents in plan, a machine for the
bending or shaping of wire rods or lengths, constructed and arranged according to
the said invention.
A wire length to be bent is shown in position between the sets, and with the
movable tools or parts of the machines, in the positions which they respectively
occupy when the said machine is at rest.
Figure 2 represents a like view as Figure 1, with a wire or rod length shaped by
the machine, and with the tools or appliances of the same in the positions which
they occupy when in operation.
Figure 3 represents a longitudinal vertical section of the said machine upon the
dotted lines A. B. Figure 2, whilst Figure 4 is a transverse section on the dotted
lines C. D. Figure 2.
Figure 5 represents a frame of a larger size, but alike in form to the one produced
by the machine Figures 1, 2 and 3.
Figures 7, 8 and 9 are other forms of base framings which admit of being
produced by our machine, by the changing of the shape of the slide shaping block
and fixed dies.
The same letters of reference indicate corresponding parts in Figures 1 to 6.
a is the fixed bed, having a channel a², directed longitudinally up its middle,

page_text: wherein a flush and dovetail edged slide works, and is reciprocated by a connecting
rod or other means connected to links, pivotedly jointed at 2, to an upright
smug, carried at the after part of the said slide 6, which carries upon its upper
side, a he shaping block e of an outside figure of the inside figure of the branches
of the article to be produced.
!, so
This slide, besides carrying upon its top side a shaping block c, carries a round
or angular stud or peg d, at a short distance from the nose e, of the block " whilst
the extreme fore part of the slide has a striking nose e, which strikes a jaw opening
slide, situated at the other end of the machine, and guided by a square block
that as the said jaw opening slide, is within the path of motion of the nose e,
it is struck by it, and made to traverse backwards, and its back side", to
impinge against the inside parts of the tail ends, of necking jaws h, pivoted
at respectively, and having at their front inner ends, gathering-in or nipping
noses *.

of the branches of the articles to be produced.
jis a coiled spring, for bringing back the necking jaws to their normal positions,
after the retiring of the slide, which has a shoulder d, which comes against a
stop a³, formed at near the back end of the channel a, and forms a stop to the
traverse of the slide.
On the shaping block, coming to the end of its forward traverse, the space
between its sides, and the sides, form cavities or side channels of the breadth and
direction which the sides of the frame is to acquire.
The slido is faced with thin choot stool to reduce the woun
TERA
Assuming the jaws to be open, and the slide and shaping block drawn back as in
Figure 1, and with a length of wire, or a rod 1, sufficient to form a frame, placed
between the sets, and with the middle part of the wire or rod coming against the
front of the peg or stud d.
On the moving forward of the slide, the wire is bent inwardly, and the branches
or ends brought between the outside edges of the shaping block c, and the inside
edges, of the dies i, and made to take a figure somewhat resembling an elongated
letter V.
The wire being thus carried forward and partly shaped, its fore part is carried
between the nipping noses of the jaws, and with the same partially wrapped round
the stud, when the impingement of the striking nose e, against the jaw opening
slide, knocks the same rearwardly, which in its turn, strikes the after ends ², of
the rocking jaws h, and causes their said after ends to open out and thereby close
their fore ends or nipping noses upon the fore part of the frame, and gather in or
neck the same forward of the peg or stud, hence the production of a frame or
article.
The opening of the necking jaws or rocking levers is performed by the
spring j.
The terminal ends of the said frames or articles may be looped prior to, or after,
the formation or shaping of the same.
The making of the frames Figures 7 and 8, which are of an elongated U forma-
tion, (which are only examples of framings capable of being produced) is performed
by changing the shape of the shaping block and dies, to the inside and outside
figures of the articles to be made or produced, and also by changing the figure of
the nipping noses of the necking jaws to the shape of the neck required, as it will
be observed that the neck in Figure 8 is longer than that of Figure 7, likewise the
neck in Figure 7 is more pronounced than that in Figure 5, and that the terminal
ends of the members of the frame Figure 7, are mouthed or opened out, and are
produced by shaping the entrances to the dies and the fore part of the shaping
block accordingly.

page_text: In producing the frame Figure 9 the necking jaws are dispensed with.
The application of our invention to the shaping of wire or rod lengths for the
production of other articles, differs in no essential respect, from the shaping of a
base framing as herein before described, other than the disposition of the stud,
the shape of the nose, or both nose and sides, of the block, and the shapes of
the jaws.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed 1 declare that what I
claim is :-
First In machinery for the shaping or bending of metallic wire lengths and
rods into various forms, by passing the same between a sliding block or tool, and
stationary or fixed dies, and which parts are arranged, combined, and perform the
work substantially as described and set forth.
Secondly-In machinery for the shaping or bending of metallic wire lengths or
rods, necking the fore part of a frame or article by necking jaws, working in unison,
and operated in manner as described and set forthi.
Thirdly-In machinery for the shaping or bending of metallic wire lengths or
rods, automatically closing or operating the necking jaws or rocking levers h, 2, 1ª,
by an interposed slide, which is struck by the fore or nose part of the slide, carrying
the shaping block for the inside shaping of the said article, substantially as described
and set forth.
Fourthly-The general construction, arrangement and combination of the parts
of machinery for the shaping or bending of metallic wire lengths and rods into
various forms for various purposes as described and set forth, and which parts
operate and co-operate in the way and for the purpose, substantially as described
and set forth.
