Machinery for the Manufacture of Wire Spring Bandings and Loop-
coiled Spring Wire Work, and in Tools to be employed in
connection with the said Manufacture.
I, PATRICK ALPHONSUS MARTIN of the Firm of Martin and Martins, of
Granville Street, in the City of Birmingham, Manufacturer, do hereby declare the
nature of this invention to be as follows:-
This invention pertains to machinery or means for the manufacture or production
of loop-coiled wire spring bandings, and loop coiled spring wire work generally,
such for example, as the wire spring bandings, or spring wire work, as described
and represented in the Specification of Letters Patent granted to John Jackson,
No. 3830 dated March, 25, 1885..
The said wire spring bandings or spring wire work of John Jackson (and known
as the "Martin") consists of a series of zig-zag arranged arms or lever lengths,
united or connected together at their ends by loop-coil springs, constituting joints,
upon which, the arms or lever lengths open out, or close, on the distension or
contraction of the same.
Machinery for the manufacture of the "Martin" wire spring banding consists of
a bed or frame work, carrying a main axis or shaft, mounted and running within
suitable bearings.
Mounted upon the said main axis is a driving crank-plate, having a connecting
rod, whose outer end is jointedly connected to the short arm of a rack acting lever,
fulcrumed to an outstanding bracket of the main framing.
The end of the longer arm of the rack lever is, by a pin or stud, connected to a
sliding rack, reciprocated within guides, and operated by the crank plate, through
the medium of the connecting rod and lever aforesaid.
The rack works horizontally, and its teeth intergear with the teeth of a pinion
or wheel, surmounting and made fast upon the upper end of a coiling member,
rotating within, and vertically suspended from, a bracket bearing of the general
framing.
Spring wire wound upon a bobbin, is directed through, and down the middle of
the coiling member, consisting of a depending carrier, connected to the lower end
of a hanging spindle, and with the carrier part fitted or provided with grooved
rollers, arranged vertically one above another, aud with their peripheries coming
lignable, & between them the wire fed is drawn.
The lower end of the said carrier has a cross bracket with depending ends; the
one side is terminated by an eye or opposed faced rollers, wherethrough, or between
which, the wire directed down the middle of the spindle passes, after the same has
passed around a pulley at one end of a rod, working horizontally through cross
holes in the said ends of the cross bracket.
Disposed between a collar on the rod, and the plain end of the bracket, is a
coiled spring, which forces the rod and pulley outwardly, and so keeps the wire
constantly taut, during the operation of coiling or twisting and directing the same
around and between rising and falling mandril pegs, as hereinafter described.
The guide eye is disposed excentric to the axis of the spindle, and rotates
around, and clear of, the pegs, between which is a post stop, to prevent the coils
and band formed, from descending or travelling downwards with the pegs, when
they descend.
The top of the stop lies in the same plane as the underside of a coil formed, so
that as the coiling member rotates, and the eye describes a circle, the wire is coiled
twice around one peg, while the top of the other peg is clear of the second, and

page_text: then twice around the top part of the second peg, when the same is clear or the
first, and so on.
The coil on one peg is in a reverse direction to that on the other, and with an
inclined length of wire disposed between them.
Vertically working slides carry the pegs, with the stop lying quiescent between
them.
These slides are worked and timed from off cams on the main axis, through
fulcrumed levers, pulled home upon the faces or peripheries of the said cams by
springs.
Stripping off of the formed coils from the pegs is performed by alternate
retirings of slides, through cams and intervening agencies.
The take-away of a formed band, consists of soft faced rollers, with ratchet
wheel and pawl, the latter operated by a jointed lever, worked by a cam on the
main axis, which has fast and loose pulleys mounted thereon, and with other well
known accessories, employed in driving mechanism.
OPERATION.
On motion being communicated to the main axis, the crank plate rotates, and by.
it the connecting rod reciprocates, and turns the rack lever, and by its radial
traverse, the rack is slid forward, and the pinion and its accessory parts rotated
with the eye wherethrough the wire runs, turned in a circle, twice around the top
part of the up peg, then this first named peg retires, whilst the other peg rises, and
before the retiring peg by its downward movement completely strips off the formed
double loop coil, the down peg has risen to its full height, with its extreme upper
end horizontally clear of the top of the now retiring peg.
The rack is now pulled in a reverse direction by the cam on main axis, when the
coiling member is re-rotated twice in a reverse direction, taking the wire from the
first formed coil across to the second and up peg, then coiling the same twice
around the said up peg in a reverse direction to that of the first, hence the
formation of two loop-coils, with an oblique or inclined arm or wire length between
them.
The inclination or angle of the intervening arm-length of wire is made, by the
dispositions of the pegs, with respect to each other.
On each loop-coil formed, the take-away means is brought into action, and
each coil with arm length of wire pulled, and then released, when the same resumes
its normal figure.
Thus, the take-away action first pulls and then releases, so that the formed band
is thereby removed from out of the range of the pegs as it is made.
The formation of spring wire-work distensible surfaces for bed sackings, seat
bottoms and the like, differs in no essential particulars from its application to that
of a two-coil band as herein described, other than the employment of a series of
pegs, according to the breadth of the resilient surface required to be fabricated.
The loop-coils may be closed or flattened, by a subsequent operation, and by the
employment of tools, consisting of a peg plate with a ratchet toothed shaped
surface or bed, which on the coils being passed collectively over the pegs, and
then pressed forcibly down onto the bed, they become symetrically and equi-
distantly arranged.
Or the closing or flattening of the coils may be performed at the same time, or
immediately after their formation, and without the same being taken or stripped
from off the pegs, on which they were formed.
Thus each coil may be pressed by a descending tool, taking over the peg, and
pressing on the coil so as to close it to a permanent set. Or a series of pegs may
be made to travel with the coils, and then be subsequently pressed before the
return of the said pegs to again do duty.
Or the coils may be transferred from the coiling pegs to carrying pegs, and
upon these last named, the pressing is or may be performed...
i

page_text: I wish it to be observed, that my invention is applicable to the formation of all
kinds of looped spring bandings of a like construction as described, and made from
spring wire.
In more clearly elucidating the flattening or closing of the coils inserted upon
the pegs of the peg-plate, and which constitutes the finishing process in connection
with the production of the spring wire band, I may add that the coils of the wire
band, as they leave the machine, are at an angle, or incline to the general plane of
the crossing connection wires or parts, and that such coils or border loop coils, are
required to lie somewhat or nearly in the same plane as the said band, and further,
that the border coils themselves, require to become more or less contiguous, in
order to form a close band, and still further, hardness is required to be imparted
to the coils, so as to maintain the springiness of the band.
The tools for forming the closing, twisting the border coils into planes
approaching that of the band, and setting the loop coils, are as follows:-
The lower tool consists of two rack bars, or ratchet toothed bars, separated from
each other to a distance equal to about the breadth of the band, and directed from
the inclines or middles of the teeth, which slope downwards from vertical or other
shoulders, are upright pegs, and fitting upon the said pegs are like rack bars, with
the planes of the teeth following those of the lower rack bars, and between which
teeth or rack surfaces, the border coils of the band come, and on the said teeth
being forced together, the said coils are shaped.
The operation is as follows :-
--
Assuming an unfinished length of wire to be taken, then the loop coils of the
same are passed alternatively over the pegs one after another, and at the same time,
the said border loop coils are brought closer to each other. This done, the upper
rack faced tool comes down, and passes over the pegs, and with the inclined planes
respectively impinging upon the loops or coils, forcing the same down the pegs,
and upon the inclined planes of the bed.
The coils, which incline upwardly from the summits of the teeth of the rack
bars are pressed down until they become parallel to the planes of the said teeth,
thereby twisting the coils, which slightly return by their elasticity, and take a dead
set in planes nearly allied to that of the band itself.
The twisting of the coils, the setting of the metal of them, and disposing of them
at equal distances apart, twists also the inclined transverse connecting parts into
proper planes.
Instead of the transverse connections of the border coils crossing each other,
they may be disposed parallel.
The fashioning of other spring wire banding than that described differs only in
respect to the shape of the tools, and the particular requirements of the special
bands.

COMPLETE SPECIFICATION.
Machinery for the Manufacture of Wire Spring Bandings and Loop-
coiled Spring Wire Work, and in Tools to be employed in
connection with the said Manufacture.
I, PATRICK ALPHONSUS MARTIN, of the Firm of Martin and Martins, of
Granville Street, in the City of Birmingham, Manufacturer, 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 pertains to machinery or means for the manufacture or production
of loop-coiled wire spring bandings, and loop coiled spring wire-work generally, such

page_text: for example, as the wire spring bandings, or spring wire work lengths, known as
the "Martin" banding.
The said wire spring banding, or spring wire-work in question, consists of a series
of zig zag arranged arms or crossing levers, united or connected together at their
ends by loop-coil-springs, constituting the border to the band and also joints, upon
which the arms or crossing levers open out or close, on the said band being distended
or on the same being contracted.
The machinery for the manufacture of the said spring banding consists of a bed
or framework, carrying a main axis or shaft, mounted and running within suitable
bearings, and made fast upon the said main axis is a driving crank-plate, having, a
connecting rod, whose outer end is jointedly connected to the short arm of a rack
lever, fulcrummed to an outstanding bracket of the main framing.
The end of the longer arm of the rack-lever is by a pin or stud, connected to a
sliding rack, reciprocated within guides, and operated by the crank plate, through
the medium of the connecting rod and lever, aforesaid.
The rack works horizontally and its teeth intergear with the teeth of a pinion
or wheel, surmounting and made fast upon the upper end of a coiling member,
rotating within, and vertically suspended from, a bracket bearing of the general
framing.
Spring-wire is payed from off a bobbin, and is directed through, and down, the
hollow middle of the coiling member, consisting of a depending carrier, connected
to the lower end of a hanging spindle, and with the carrier part fitted or
provided with grooved rollers, arranged vertically one above another and with
their peripheries coming lignable, and between them the wire fed, is drawn.
The lower end of the said carrier has a cross bracket with depending ends; the
one side is terminated by an eye or opposed faced rollers wherethrough or between
which, the wire directed down the middle of the spindle passes, after the same has
passed around a pulley at one end of a rod, working horizontally through cross
holes, in the said ends of the cross bracket.
Disposed between a collar on the rod, and the plain end of the bracket is a
coiled spring, which forces the rod and pulley outwardly, and so keeps constantly,
taut, the wire, during the operation of coiling or twisting and directing the
same around, and between, rising and falling mandril pegs, as hereinafter
described.
The guide eye is disposed excentric to the axis of the spindle, and rotates
around and clear of the pegs, between which is a post stop, to prevent the coils
and band formed, from descending or travelling downwards, with the said pegs
when they descend.
The top of the stop lies in the same plane as the underside of a coil formed, so
that as the coiling member rotates, and the eye (or guide rollers) describes a circle,
the wire is coiled twice around one peg, while the top of the other peg is clear of
the second, and then twice around the top part of the second peg, when the same is
clear of the first and so on.
The coil on one peg is in a reverse direction to that on the other, and with an
inclined length of wire disposed between them.
Vertically working slides carry the pegs, with the stops lying quiescent between
them.
These slides are worked and timed from off cams, on the main axis, through
fulcrummed levers, pulled home upon the faces or peripheries of the said cams by
springs.
Stripping off of the formed coils from the pegs is performed, by alternate retirings
of the slides, through cams and intervening agencies.
The take-away of a formed band consists of soft faced rollers, with ratchet wheel,
and pawl, the latter operated by a jointed lever, worked by a cam on the main
axis, which has fast and loose pulleys mounted thereon and with other well known
accessories, employed in driving mechanism.
Figure 1 of the accompanying drawings, represents, in plan, machinery for the

page_text: manufacture of the "Martin" wire spring banding, constructed and arranged
according to my invention.
A left hand part of the said machine is shown broken away, in order to exhibit a
portion of the slide, and its connection with the pin of the connecting rod, and
through which slide, the rack for giving an alternate reciprocation to the twisting
spindle, is operated.
Figure 2 represents a plan of the lower bed, or.a plan of that part of the machine
supporting the rising and falling, slides, which carry the rising and falling pegs

machinery, with the lower bed in section, and with the driving part of the
machinery cut away.
It also shows in section, the coiling frame terminating the lower part of the
rotating spindle, which is made to alternately rotate through the medium of the
reciprocating rack.
Figure 4 represents upon an enlarged scale to that of Figure 3, the pegs upon
which the coiling of the loops is performed.

Figure 12 is an edge view of the same.
Figure 13 is a part section and part elevation of the tools employed in the
setting up of the band Figures 9 and 10, transforming the same into the band
Figures 11 and 12.
Figure 14 is an inverted plan of the upper tool Figure 13, and Figure 15 is a
top side plan of the lower tool of the pair of tools Figure 13.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.
The said machine consists of a top mechanism upper supporting bed a, mounted.
at the summit of an upright framing a', suitably supported by, and bolted at its
lower part to, a lower bed a², supported by legs a³, upon which bed the bottom.
mechanism of the machinery is also carried.
The driving shaft, which is marked b, runs and is mounted within bearings 62,.
and which shaft has made fast upon it, cams c and d. for the working of the
mandril pegs, around which the loops of the band are formed as hereinafter,
described, and a driving crank plate e, with stud or crank arm e² прол
its face, to
which the right hand end of the connecting rod f, is connected and jointed.
This said shaft also carries a take-off cam g, for operating mechanism for
alternately pulling the loops of the coils formed from out of the range of a loop.
being formed.
Also running loosely upon the said shaft is an idle pulley and made fast to the
shaft is a fast pulley i, and a hand wheel j.
The left hand end of the connecting rod, is jointed by a stud or pin 2, to the
short arm p², of a rocking or rack lever p, fulcrummed at p', and with the upper
end of the long arm p³, connected by a stud or pin, to a reciprocating slide k,
carrying a toothed rack k², whose teeth intergear with the teeth of a pinion m,
J

page_text: mounted and made fast upon the upper end, of a hollow and revolving spindle or
coiling member n, terminated at its lower end by a bracket carrier q, by which the
tensioning and twisting part of the mechanism is carried and rotated.
Now the rack 2, is made adjustable by an end bolt 3, and the slide is made
to reciprocate steadily within its frame by a dovetail base k¹.. The rocking
lever p, is adjustable at both ends, whilst the revolving spindle or coiling
member n, is suspended and revolves within a bracket k', bolted to the upright
framing a¹.
The coiling member, which consists of a hollow spindle n, freely rotating within
bearings, and operated by the pinion and rack, carries a bracket g, which is fitted
with tensioning rollers q', g2; the former g', turn upon axes made fast upon the
bracket, whilst the latter g, turn upon axes q³, carried by an adjustable bearing
carried by the bracket carrier, and adjustably fitted by a screw pin q.
Now as the spring wire o, is payed out from off a bobbin or the like, and is
conducted down the middle of the spindle of the coiling member, and drawn between
the rollers 9, 92, whose inner peripheries lie out of a vertical plane on their inner
presented sides, and give a wave figure to the wire being drawn therethrough,
automatic self-tensioning of the wire is performed as the same is drawn over the
pulley r, mounted at the end of a self-tensioning and sliding spindle 7, working
within guides 2, of a cross-head bracket 3, and located between a collar 4, and
the outer end of the said crosshead bracket 3, is a coiled spring, which forces
the rod or spindle r', forcibly outwards, and keeps the wire being fed through the
guiding rollers constantly on the stretch during the operation of coiling or
twisting.
The one end of the carrier bracket, on the pulley side of the coiling
member, is made of a hanging construction (marked 6), and forms the carrier
bearing for two horizontally directed and grooved guide rollers s, between the
grooves of which, the inner end o¹, of the spring wire o, to be fabricated into a wire
spring band is drawn by a coiling action.
Thus the rollers. s, are excentric to the axis of the coiling system, and rotate in a
circle around one or other of the mandril pegs t, t¹, according to which one is up,
and which pegs are carried by vertically-working slides ³, t³, rising and falling
within guides t, and being worked by rocking levers u, u', fulcrummed at u³,
and taking their motion from off the cams c and d, respectively upon the main
shaft b.
The rocking levers are connected at their inner ends to the slides t², t³, by
studs to, and have at their outer and cam ends, nose pieces, u³, u', which come upon
the peripheries of the cams, and follow their contour by being drawn down by
springs u, u.
Now the mandril peg-operating cams c, and d, are each formed with stripping
rises c, d, clearance rises c', d', and lifting faces c³, d³, so that the said mandril
pegs are respectively lowered first for clearance, secondly for stripping and then
lifted again for recoiling.
Now the wire being coiled is rotated first in the one direction about twice around
one of the mandril pegs when the same is up, then the said peg, with the coil upon
it, falls to a position below and clear of the next loop coil to be formed, which is
coiled in a reverse direction upon the second mandril peg, which has ascended at
the same time that the other peg descended. Then the first named peg, after the
coil has been formed on the second peg, falls to a lower degree, when the loop coil
formed is tripped from off it, and is at the same time drawn out of the way by the
take-away mechanism v, consisting of rubber faced wheels v', mounted upon axes v²,
and driven and intergeared by toothed wheels v³, and fitted with a ratchet wheel v₁,
having a wiper pawl, carried by a loose and reciprocating rocking arm vⓇ, brought
back by a spring 7, and operated forward by the long arm w³, of a lever w,
fulcrummed at w, and taking its motion from off a cam 9, through the short arm w³,
which is made to horizontally rock and work the said, band take-off primarily by
the swell gl.

page_text: operat
represented in Figures 9 and 10, and is subsequently set-up or
upon by tools Figures 13, 14 and 15, to produce the finished banding 11 and 12.
The movements of the slides of the mandril pegs are limited or controlled by
stops u, whose legs come upon the lower bed, and keep the said slides, or the
mandril pegs, at a dead height, without any variation whatsoever in the relative
positions of the pegs when working, whilst the coils are stripped from the pegs by a
stripper y, in the form of a fixed stop, carried by or from a fixed part of the
framing, so that as the said pegs descend, or are lowered by their slides below. a
given point, the impingement of the crosswire of coil against the stop prevents the
coils being carried down with the pegs, hence the stripping.
OPERATION.
Assuming that the machinery has been set in motion, and that a coil has been
formed upon the mandril peg t, and that a partial coil has been put upon the mandril
peg ; then as the shaft b, continues to rotate, and communicates motion to the
crank or stud plate e, and through its stud or crank pin e², to the connecting rod f,
which turns the rock lever p, upon its centre p¹, the slide k, is traversed from left
to right, and with it, the rack k², the motion of which is indicated by the arrow.
Now the rack is shown as having traversed through a distance of about two-thirds
of its throw, so that the up peg t, has formed upon it a part coil, which is then
completed by the rack making its full traverse and the coiling member a double
rotation in the one direction as indicated by the curved arrow.
At this juncture, the swell d2, of the cam d, has been brought up to the nose u³,
of the rock lever u, and then momentarily depresses the slide t², through the said
lever u, to its fullest extent, and with it the peg t, and on the crossing wire a², of
the coils, coming or impinging upon the fixed stop y, whilst the said peg t, still
descends, the coil, is stripped, and now being free, the band is then stretched and
the loops distended, and the last formed loop brought away clear of the peg upon
which it was formed, which now fully rises by the part d³, of the cam d, being
presented to the nose of its slide rocking lever.
There is now upon the peg t¹, a full coil, which now falls or descends with its peg
at the same time as the other peg t, rises to a position for receiving another coil,
but the top of the peg t¹, has been lowered to a position below and clear of the
lower loop of the coil again to be formed upon the peg t.
The rack now reciprocates in a reverse direction through the action of the crank
plate, connecting rod, rocking lever and slide, and as the peg t, with its coil, is now
in a position of its first descent, a twice-round movement in a reverse direction of
the coiling member ", q, is made, which puts upon the peg t¹, another coil, and
immediately on its completion, the coil a, is stripped from the peg t by the said peg
fully descending and is pulled by the take-off thus taking it out of the range of the
peg upon which it was formed. The said peg t, then immediately rises, and as the
same ascends, so the peg t¹, with its coil, makes the first stage of its descent, so as
to bring its top clear of the next coil to be formed upon the peg t, which has just
risen. Now as the rack is traversed in a reverse direction, and the up peg t, is
within the path of the coiling wire, the said wire is coiled twice around this peg as
a centre, as before, and so on alternately coiling upon the one peg and then upon
the other peg in reverse directions.
20,
In the take-off, whose motion is taken from the main shaft through the swell g¹,
which
of the cam g, coming against the end of the short arm w³, rocking the lever
operates the arm ve, and through it the pawl v, turning the ratchet wheel, hence
the rotation of the axes v², and the take-off wheels, which intermittently draw
away, and at the same time stretch the band æ, formed. The act of stretching and
delivery comes into operation at the time immediately following the stripping of a
loop from a peg, and the taking of the same out of the range of the peg thus
stripped when again ascending.

page_text: The band x, (see upon a full scale in Figures 9 and 10) now requires to be set
up, so as to produce a band alike unto that of Figures 11 and 12.
Thus the said banding x, is converted into a banding a³, by a subsequent operation,
by the employment of tools Figures 13, 14 and 15.
In Figures 13, 14 and 15, 1 is an upper tool, having ratchet-tooth shaped facings 1,
separated from each other by a clearance or distance piece 1', and with each tooth
or inclined plane, having within the middle of it, a hole 1, wherein a peg 2", in the
middle of each of the ratchet-toothed planes or surfaces 2ª, of the bottom tool 2,
takes, and ensures a proper registering or coinciding of the opposed acting surfaces
of the inclined planes which may be separated in both cases by clearances or
distance pieces 1b, 2b, and which set up the coils, so that the whole of the said coils
will become practically horizontally lignable.
The process of setting up the coils is performed by placing a number of coils a¹,
upon the pegs of the lower tool 2, and then forcing the upper tool 1, down upon the
lower one, with the coils a¹, between the opposed and ratchet-toothed surfaces or
inclines. By this compression, or forcing home of the upper tool. the coils are
twisted about their joining members a², beyond the positions which they require to
assume, so that when bent or twisted to such a degree and then subsequently
released, the springiness of the metal brings the coils back to a lignable or given
plane, as represented in the plan Figure 11 and the edge view Figure 12.
Thus after a length of spring banding Figures 9 and 10 has been formed by the
machinery as herein before described, given lengths of the same are then operated
upon by placing the loops upon the pegs of the lower tool, and then bringing the
upper tool down upon the said lower one, whereby the loops of the coils are set up,
and their planes adjusted by first distorting the planes of them by applying torsion
to the joining members, and then on the upper tool being removed from the lower
tool, the said loops spring back, and take a general plane, as in Figure 12, and with
the loops of the coils symetrically and equidistantly arranged.
Or the disposing of the planes of the coils, and permanently setting the same up
may be performed during the formation of them upon the pegs, and prior to stripping,
by providing the shanks of the pegs with inclined shoulders or planes, and arranging
for a descending setting-up tool to come upon the coil, and press the same to the
plane of the shoulder, and which when released, springs back to a given plane.
Or the unfinished band, as it leaves the machine may be conducted upon travelling
pegs constituting a lower tool, and then in an intermittent manner an upper tool
descends, and forces the coils of the band between ratchet shaped planes.
In addition to the proper disposing of the planes of the coils, all irregularities in
their positions are rectified, and further the coils are closed if not sufficiently
together, and further the metal is made to take a permanent set, and additional
springiness is thereby imparted to the coils by the crystallizing of the metal.
Instead of the border coils having crossing or oblique connection wires or
members, they may be united by parallel crossing members.
The finishing and fashioning of the coils of other wire spring bandings differs in
respect to the shape of the tools, and the special requirements of particular bands.
The application of my invention to the production of spring wire work distensible
surfaces generally, and particularly to those employed for bed sackings, seat
sackings and the like, differs in no essential respect from its application to the
manufacture or the production of a two-coiled band as herein described, other than
in the employment of pegs in number equal to the number of coils in the breadth of
the spring surface to be fabricated.
Further, instead of each coil being made of two loops, each coil may have one,
three, four or other number of loops. In such a case, the coiling member is made
to rotate once, three times, four or other number of times around the pegs, and
further in order to prevent the loops of the coils riding one upon another when
there are more than two loops to coil to be formed, the pegs are made to have
part continuous and part intermittent rising and falling movements, at given periods
and sub rata with the coiling.

page_text: It will be seen that the ratchet toothed surfaces of each tool are in double order,
and arranged differentially or non-coincident, according to the pitch or inclination
of the connecting limb members of the loops.
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 In machinery for the manufacture of wire spring bands or bandings
formed with loop coils or having borders of loop coils, producing an alternate
rotatory movement of the coiling member by or through the medium of a rack and
pinion, with the latter connected to the rotating spindle of the coiling member,
substantially as described and set forth, in Figures 1 to 8.
Secondly-In machinery for the manufacture of wire spring bands or bandings
formed with loop coils, or having borders of loop coils, forming the coils or the
loop coils by delivering or drawing the wire through or between excentrically
arranged or mounted guide rollers, guide eyes or their equivalents, markeds,
substantially as described and set forth.
Thirdly-In the coiling member of machinery for the manufacture of wire
spring bands or bandings formed with loop coils or having borders of loop coils, the
combination with a spindle, mounted and hung within bearings, and driven by a
pinion made fast to it, of a carrying bracket, with a depending and excentrically
disposed eye or bracket part, coming lignable with, and outside, mandril pegs,
around which the wire is coiled, by the said eye or bracket part making a single,
double or other rotation about a peg or the pegs as a centre or centres of motion,
substantially as described and set forth in Figures 1 to 8.
Fourthly In the coiling member of machinery for the manufacture of wire
spring bands or bandings formed with loop coils or having borders of loop coils,
the combination with the carrier bracket part of the coiling member of self-
tensioning means for the tightening of the wire, substantially as described and set
