Improvements in Machinery for the Manufacture of Coiled Wire
Fabrics.
I, CHARLES HARTLEY HARD, President of the Hard Manufacturing Company
of Oneida, in the County of Madison, State of New York, United States of
America, now residing at the Grand Hotel in the City of Birmingham, England,
do hereby declare the nature of this invention to be as follows:-
This invention relates to detail improvements in machinery for the manufacture
of coiled' wire fabrics for mattresses, sackings, seatings, mats and other articles of
an analogous nature, and is an improvement upon Letters Patent granted to the
present applicant conjointly with Orrin Filmore Franks and Albert Edward
Loomis dated the 4th day of November 1890 and numbered 17717.
"
The machinery consists of a horizontal bed, of any desired area, according to
the fabric to be woven. This bed is fitted with a reciprocating slide, carrying a
pair of fluted coil-supporting rolls, coupled together by gear, and driven by the
movement of a ratchet and pawl on the axis of one of them and receiving
intermittent motion from a cam on the main shaft through the medium of levers or
links. The aforesaid slide is intermittently reciprocated by a cam on the main
shaft also through compound arms or links.
Situated at the fore part of the framing, immediately in front of the rolls, is
a cutter adjustably mounted on the framing and automatically worked by a cam
on the main shaft, whilst disposed in front of the entrance to the fabric supporting
rolls, are a pair of feed rolls, mounted in an obliquely-directed bracket, and driven
in unison by a large gapped toothed wheel mounted on the main shaft. These rolls
are adapted to feed the wire into the coiler, which consist of a helically grooved
tool, wherethrough the wire from the feed passes and has a spiral form given
to it, and the rotatory motion imparted to the wire in forming the helix is
utilized in traversing the same along and making the same pick up the preceding
helix which is held by the supporting rollers.
After each helix has been made and interwoven with the preceeding one, it is
then cut off to a determined length, according to the length of fabric being woven,
by the automatic cutter before mentioned.
The feed rolls, after the necessary helical length has been formed, interwoven
and cut off, are stopped, and at the same time the reciprocation of the slide is
brought about through the medium of a closer sector, mounted upon a main axis:
and adapted to fill up the gap in the gapped toothed wheel, and the supporting
rolls are turned through a part of a circle to an extent equal to one flute, so as to
release the lower coil and clip the one last threaded.
The large toothed and gapped wheel is driven by a pinion on the driving axis,
which carries suitable clutch mechanism for starting and stopping the machine.
Situated at the front of the feed are two skeleton bobbins or reels, around
which the wire to be fed is wrapped, which reels are driven by leather faced
friction wheels, . thrown out of gear by a cam bar, adapted to throw the reels'
and their driving plates out of gear by bodily lifting the spool and taking the
friction parts which are driven from off the main shaft, out of contact with one
another.
:
To prevent the spools over-racing themselves, the same are provided with
governors which control, through self-acting means, the amount of frictional

page_text: contact which the parts shall have with one another, and thus the amount of feed
is equalized by the frictional gear being allowed to slip or release itself when the
speed is too high, hence a uniform feed.
Overhead guides or jiggers direct the wires (in double weaving) to a common
point in the feed rolls and prevent the wire from looping.
The length of feed is determined by employing a change of wheels at the end of
the feed rolls opposite to the gear, which change wheel is placed upon the axis
of the top feed roll and intergears with an intermediate motion transmitting wheel,
mounted in an adjustable bearing and driven from the large toothed wheel
aforesaid.
To determine the breadth of fabric to be woven, a change wheel of a greater or
less diameter is applied so as to cause the feed rolls to deliver in their feed more
or less wire.
The large toothed driving wheel on the main shaft makes one complete revolution
to every feed of the rolls, whether the fabric be narrow or wide, as the difference
in breadth is provided for by the gearing up of the feed rolls.
Carried upon one side of the toothed wheel on the main axis is a drum, having a
series of five or other number of markings upon the periphery, graduated into
equal divisions corresponding to like divisions set out upon a horizontal scale or
measure carried by and directed in the longer direction of, the bed and at the side of
the fabric supporting rollers before referred to. Situated upon the fixed framing,
adjacent to the first named graduated drum, is a fixed pointer, to which one or
other of the graduations is brought by freeing the intermediate wheel from gear
with the principal toothed wheel, which, when out of mesh is capable of being
turned, and any of the graduations on the drum brought round to the pointer.
Thus, in setting the traverse or throw of the coil, assuming that a given breadth
ie to be woven, first start the machine by hand, and make the coil traverse to the
given breadth, and assuming that it has been brought to 72 inches on the bed
scale, then the graduated drum is rotated till the 72 thereon is brought up to the
pointer. This will adjust the cams to their proper relative times. Now again fix
the graduated drum in its adjusted position by bringing the intermediate wheel and
its bracket, by means of a lever, into mesh with the principal toothed wheel, when
the coil evolved from the coiler will be delivered and run through the given length
of 72 inches.
It is understood that the series of graduations of the drum correspond to the
change wheels, that is, each ring graduation corresponds to the particular change
wheel with which it is employed.
The rotatory movement of the supporting rollers and the reciprocation of the
frame carrying them is made through a double cam, loosely mounted upon the
main shaft or axis, and made fast thereto by a clutch peg working through a boss
on the said shaft and taking into a clutch hole in the double cam, which hole
has a suitable lead. The said clutch peg or stud is carried by a hanging and
rocking lever, jointed at its lower end to a connecting link whose other end is
jointed to one end of a lever, having an inclined end, arranged to come within the
path of a series of faced cams carried by a cable or time wheel, which determines
where the common weaving is to cease and the parts of the fabric at which
compound weaving is to be conducted or a cable or thickening stripe inserted.
The said cable or time wheel, which is toothed upon its periphery, has inter-
gearing with it a worm, driven by a bevel wheel intergearing with another bevel
wheel on the principal axis. The cams on the face of the cable wheel are
detachable and adjustable so that the spaces between the cables in the fabric may
be determined.
Thus, when one of the cable spacing cams is taken round by the wheel, it
comes against the inclined end of the lever and pushes the same out of its path,
and thereby takes the clutch peg out of the cams thus causing a cessation of
the movement in the supporting rollers and their traversing slide during the
formation of the cable.

page_text: The cable wheel also carries an adjustable stud for operating a warning bell,
which indicates by its ringing that the desired length of fabric has been
completed.
Situated rear of the exit end of the coiler or giraffe is a threader, universally
adjutsable, or adjustable in four directions, viz., a back and forward adjustments,
a vertical plane adjustment and a tilting adjustment.
The said threader consists of a tool having a helical groove or a differentially
cut helical groove formed around its periphery, in which the wire from the coiler
runs for steadying the coil in its intercoiling passage into the shed of the prior
coiled helix. This threader is carried in a bracket which is universally adjustable
by pins, and works in common with the upper blade or knife of the cutters which
cut off the coiled wire.
The clutch on the driving shaft has an electrical switch for making and breaking
the electrical circuit which stops the machine in case the same should in any way
go wrong. The stopping apparatus consists of an insulated steel bar mounted on
the bed plate adjacent to the supporting rolls, and having attached to it a circuit
wire connected with a battery, the other wire of which is connected with the
framing and clutch.
As a modification of the governor part of my invention, the jiggers or hangers
are suspended from a spring having depending from it, a rod, loosely connected at
its lower end to a lever, which is jointedly connected at its inner end on a bar
coming under the friction reel forming the basis to the reel, so that should the reel
race, then the slack of the wire admit of the hauger or suspended pulley rising by
the contraction of the spring. The result is that the end of the long lever is
raised, and by it the friction driving plate is lifted and the frictional contact between
it and the driving rollers is partially relieved, when the speed of rotation of the
reels is reduced.
The frictional gear may consist of two cones rolling one upon another, with one
cone laterally adjustable through the influence of a lever operated through the
tension or slack of the wire being fed.

Improvements in Machinery for the Manufacture of Coiled Wire
Fabrics.
I, CHARLES HARTLEY HARD President of the Hard Manufacturing Company
of Oneida, in the County of Madison, State of New York, United States of
America, now residing at the Grand Hotel in the City of Birmingham, England,
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 detail improvements in machinery for the manufacture
of coiled wire fabrics for mattresses, sackings, seatings, mats and other articles of
an analogous nature, and is an improvement upon Letters Patent granted to the
present applicant conjointly with Orrin Gilmore Franks and Albert Edward.
Loomis dated the 4th day of November 1890 and numbered 17717.
The machinery consists of a horizontal bed, of any desired area, according to
the fabric to be woven. This bed is fitted with a reciprocating slide, carrying a
pair of fluted coil-supporting rolls, coupled together at one end by gear, and driven
by the movement of a ratchet and pawl on the axis of one of them and receiving

page_text: intermittent motion from a cam on the main shaft through the medium of levers or
links. The aforesaid slide is intermittently reciprocated by a cam on the main
shaft also through compound arms or links.
Situated at the fore part of the framing, immediately in front of the rolls, is a
cutter adjustably mounted on the framing and automatically worked by a cam on
the main shaft, whilst disposed in front of the entrance to the fabric supporting
rolls, are a pair of feed rolls, mounted in an obliquely-directed bracket, and driven
in unison by a large gapped toothed wheel mounted on the main shaft. These
rolls are adapted to feed the wire into the coiler, which consists of a helically
grooved tool, wherethrough the wire from the feed passes and has a spiral form
given to it, and the rotatory motion imparted to the wire in forming the helix is
utilized in traversing the same along and making the same pick up the preceding
belix which is held by the supporting rollers.
After each helix has been made and interwoven with the preceding one, it is
then cut off to a determined length according to the length of fabric being woven,
by the automatic cutter before mentioned.
The feed rolls, after the necessary helical length has been formed, interwoven
and cut off, are stopped, and at the same time the reciprocation of the slide is
brought about through the medium of a jointed sector arm mounted upon a main
axis and adapted to hold the feed rolls stationary whilst the threaded helix is cut
off, the supporting rolls turned through a part of a revolution to an extent equal
to one flute, so as to release the lower coil and clip the one last threaded, and also
whilst the slide.carrying the said feed rolls is reciprocated.
The large toothed and gapped wheel is driven by a pinion on the driving axis,
which carries suitable clutch mechanism for starting and stopping the machine.
Situated at the front of the feed are two skeleton bobbins or creels, around
which the wire to be fed is wrapped, which creels are driven by leather faced
friction wheels, thrown out of gear by a cam bar, adapted to bodily lift the spools
and take the friction parts, which are driven from off the main shaft through the
medium of suitable gear, out of contact with one another.
To prevent the spools over-racing themselves, the same may be provided with
governors which control, through self-acting means, the amount of frictional contact
which the parts shall have with one another, and thus the amount of feed is
equalized by the frictional gear being allowed to slip or release itself when the
speed is too high, hence a uniform feed.
Overhead guides or jiggers direct the wires (in double weaving) to a common
point in the feed rolls and prevent the wire from looping.
The length of feed is determined by employing a change of wheels at the end
of the feed rolls opposite to the gear, which change wheel is placed upon the axis
of the bottom feed roll and intergears with an intermediate motion transmitting
wheel, mounted in an adjustable bearing and driven from the large toothed wheel
aforesaid.
To determine the length of fabric to be woven, a change wheel of a greater or
less diameter is applied so as to cause the feed rolls to deliver in their feed a greater
or less length of coiled wire.
The large toothed driving wheel on the main shaft makes one complete revolution
to every feed of the rolls, whether the fabric be narrow or wide, as the difference
in length is provided for by the gearing up of the feed rolls.
Carried upon one side of the toothed wheel on the main axis is a drum, having a
series of seven or other number of ring markings upon the periphery, each graduated
into a progressively increasing number of equal divisions (say from 65 to 71)
corresponding to the divisions set out upon a horizontal inch scale or measure
carried by, and directed in the longer direction of, the bed and at one side of the
fabric supporting rollers before referred to. Situated upon the fixed framing,
adjacent to the first named graduated drum, is a pointer, to which one or other of
the graduations, of any particular ring scale, according to the width of fabric
being woven, is brought by freeing the intermediate wheel from gear with the

page_text: principal toothed wheel, which, when out of gear is capable of being turned, and
any of the graduations on the drum brought round to the pointer.
Thus, in setting the traverse or throw of the coil, assuming that a given length
is to be woven, first start the machine by hand, and make the coil traverse to the.
given length, and assuming that a length of 71 inches is being woven and that the
coil being fed by hand has been brought to 60 inches on the bed scale, then
the graduated drum is rotated till the 60 thereon is brought up to the pointer.
This will adjust the cams to their proper relative times. Now again fix the
graduated drum in its adjusted position by bringing the intermediate wheel and its
bracket, by means of a lever, into gear with the principal toothed wheel, when the
next coil evolved from the coiler will be delivered and ran through the proper full.
length of 71 inches.
It is understood that the series of graduations of the drum correspond to the
change wheels, that is, each ring graduation corresponds to the particular change
wheel with which it is employed. Thus the ring scale divided into 71 inches is
employed in conjunction with a change wheel which will make the feed rolls deliver
a coil 71 inches long, and so on.
The rotatory movement of the supporting rollers and the reciprocation of the
frame carrying them is made through a double cam, loosely mounted upon the
main shaft or axis, and made fast thereto by a clutch peg working through a boss
on the said shaft and taking into a clutch hole in the double cam, which hole has
a suitable lead. The said clutch peg or stud is carried by a hanging and rocking
lever, jointed at its lower end to a connecting link whose other end is jointed to one
end of a lever, having an inclined end, arranged to come within the path of a series
of faced cams carried by a cable or time wheel, which determines where the
common weaving is to cease and the parts of the fabric at which compound weaving
is to be conducted or a cable or thickening stripe inserted.
The said cable or time wheel, which is toothed upon its periphery, has inter-
gearing with it a worm, driven by a bevel wheel intergearing with another bevel
wheel on the principal axis. The cams on the face of the cable wheel are
detachable and adjustable so that the spaces between the cables in the fabric may
be varied as desired.
Thus, when one of the cable spacing cams is taken round by the wheel, it comes
against the inclined end of the lever and pushes the same out of its path, and
thereby takes the clutch peg out of the cams, thus causing a cessation of the
movement in the supporting rollers and their traversing slide during the formation
of the cable.
The cable wheel also carries an adjustable stud for operating a warning bell,
which indicates by its ringing that the desired breadth of fabric has been completed.
Situated rear of the exit end of the coiler or giraffe is a universally adjustable
threader, consisting of a tool having a helical groove or a differentially cut helical
groove formed around its periphery, in which the wire from the coiler runs for
steadying the coil in its intercoiling passage into the shed' of the prior coiled helix.
This threader is carried in a bracket which is universally adjustable and works
in common with the upper. blade or knife of the cutters which cut off the
coiled wire.
The machine is provided with an electrical switch for making and breaking the
electrical circuit which stops the machine in case the same should in any way go
wrong.

The same letters of reference iudicate corresponding parts in the several figures
of the drawings.
Mounted upon upright axes or spindles a¹, carried by slide rests or carriers a,.
whose opposite tenon sides a², are supported upon and works within opposite-
grooves, formed with a cross bed b³, of an end framing 2, bolted across the back.
end of the primary framing b, are a pair of rotating and independently mounted
and adjusted creel frames or bobbins a³, carrying bundles of wire c, which rest
upon the topside of the pulley bases a, each having an underside boss a, bearing
upon a jointed and rising and falling arm a, pivoted at a', to the slide rest
carrier a, through the opposite side bossed parts 8, of which, traversing shafts a³, a,
having their respective opposite ends wormed, pass, with one wormed end passing.
through the screw box all, in one side of the one carrier, and the other passing.
through the screw box a", of the other carrier, so that as the said traversing shafts.
are rotated either by the handles a¹³, or hand-wheels a", at the near or off sides of
the machine, the slide rest carriers and with them, the creel frames, are traversed
and the said creels, with their bundles of wire, are made to approach or recede
from cach other and their relative speeds increased or decreased by bringing parts.
of the undersides of their pulley bases of greater or less diameter over the
peripheries of one or other of the leather faced friction drums d, d¹, and d², d³,..
which are made fast on the creel-driving shaft d, which works within bearings or
journals d', supported by the principal framing b.
Thus, the nearer the friction pulleys are to the centres of the creels,, the greater
is the speed at which the said creels are driven, so that by taking the friction,
pulleys nearer to the spindles of the creels the said creels are rotated at a higher
speed and the wire paid out accordingly.
When the pulley d', is clear of the creel pulley base a, then the driving friction
pulley d, is operative and drives the creel in the direction of the arrow Figure 1,...
but on the other said friction pulley d', being brought into operative contact with
the ereel pulley base, then the said creel is rotated in the reverse direction. The
traversing screws both give the traverse to the creel bases for adjusting their speed
and also for bringing them into operative contact with either their off or near side-
friction pulleys.
The creels are stopped by the pulley bases a, and their bundles of wire, being
bodily lifted from out of contact with their friction pulleys d, d¹, d³, d³, by the
pair of lifting levers a, by a facetted cam bar e, turning within bearings e², at.
opposite sides of the framing of the machine, with the same being partly rotated:
by a crank arme, having jointedly connected to it, a link es, whose forward end is.
jointed and connected at e', to a crank arme, made fast to an axis e³, supported by
a pillar bracket e, carried by the general bed 64, of the framing b, so that by
turning the said axis e, through the medium of the handle e, the cam bar is.
rotated through a quarter of a revolution and the creel pulley bases are lifted from.
out of contact with the friction pulleys.
Motion is communicated to the creels from the driving shaft f, which is directed:
laterally across the back of the machine, through the bevel wheel f¹, intergearing
with an intermediate toothed wheel, which itself drives a toothed wheel f³, made
fast on the creel driving shaft d⭑.
'
The said driving shaft f, works in bearings f carried by the general framing b....
and runs parallel with, but at a lower plane than, the creel-driving shaft d², and is -

page_text: connected at its off-side end with clutch mechanism f", operated by the branched
or bifurcated end f, of a swinging and depending arm, jointed to the framing
at f, and operated or rocked by a connecting rod or link f running across the
framing and jointed at its near side end to a cranked lever fo, jointed in turn at f
to the after end of a rod 12, whose fore end is connected to a stopping and starting
lever, pivoted to the framing at 1, and terminated at its upper part by a
handle The said lever is normally held in its operated position by the bell
cranked catch lever f, whose hooked end, engages with a shoulder 6, of the
bed and is drawn to a stop position when the catch is disengaged by a spring 18,
connected to it and the main framing.
The wires co, in their passage from the creels to the feed rolls pass through
spring suspended pulleys or jiggers e, for preventing them from looping, and then
converge at 3, and pass through small and cross directed straightening rolls c³,
mounted in the gap e, of a bracket co, carried from the holsters c carrying the
upper and lower feed rolls and 9', coupled together at both ends by two pairs of
toothed wheels g³, 9³, and 98, 9³, made fast upon the spindles 94, 97, whose necks
work within bearings fitted within the said holsters and brought together by
springs g which equalize the nip of the rolls.
The upper roll g, is divided or split into two halves each independently mounted,
whilst the lower roll g¹, is solid, and the peripheries of these rolls are respectively
formed with coincident channels or grooves, which, on coming together, form a
series of passes g18 for the wires, and in the present instance, for double weaving,
only two of these passes are engaged at a time.
.
The double wires, after leaving the small straightening rolls, pass through two
of the series of 8 passes formed through a trunk guide c', with the nose end_c
being presented to the division between the meeting peripheries of the feed rolls,
and after the wires have passed tlirough the rolls they are then fed forward and
forced through double passages c, in the throat of the giraffe or coiler clo, which
consists of a helically grooved mandril c", supported in common with the throat by
a bracket e, from the holsters of the feed rolls.
The axis g of the split rolls g, is outwardly terminated by a square end 920, for
turning the said rolls by a handle when necessary. The said axis g, is split at g¹º,
at the division of the rolls. The near side end of the axle g7, has fast upon it, an
attachable and detachable toothed pinion or change wheel ge, which intergears
with an intermediate toothed wheel ", receiving its motion from the large toothed
wheel, driven by the pinion h, fast on the driving shaft f.
The said intermediate wheel g", is loosely mounted upon a spindle g¹³, adjustable
by a set screw g¹ within bearings of a lifting and swinging quadrant arm g¹³, hung
from the end of the axis g, inward of the change wheel g¹, and adapted to be
taken out of tooth with the large wheel by rotating the handle e, which has upon
its spindle a circular cam e³, working within the loop or strap g, in the end of the
arm g, so that by turning the handle e", both the creels are stopped and the feed
rolls arrested in their notion simultaneously.
The large wheel h, is fast upon the main shaft 2, and contains within itself
means for momentarily and periodically stopping the movement of the feed rolls.
whilst the automatic cutting-off of the wire and other movements to be here-
after described, are effected, and has upon its off side, a drum 20, marked with
cross and other graduations for facilitating the setting of the machine on
re-starting.
:
The said large wheel is rotated in the direction of the arrow in Figure 17, and
has working in conjunction with it, a counterpoised sector arm h³, with the toothed
end, having a radial movement or traverse within a gap or sinking h³, formed out
of the normal breadth of the wheels periphery. The middle of the sector arm is
formed into a drum, having located within it, a volute spring h², with one part
made fast to a boss, keyed to the shaft, and the other end attached at A, to
the inside of the drum. The tail end of the said arm has a counterpoise, whilst ..
the sector end, which keeps the feed rolls at rest during the time which it takes

page_text: for the wheel to travel a distance equal to the space lying between the head of
the toothed quadrant and the shoulder " of the wheel, by the said sector arm
remaining quiescent and holding the rolls stationary with it during the said portion
of the wheels rotation.
The sector arm is held during the feeding movement of the rolls by the catch
end of a jointed catch ³, fulcrumed at 4, and normally pressed outwards
by a spring, and having a curved tail end h, which on each rotation of the
wheel, is timed to wipe over a swell or rise 6º, coming within its path and carried
by the main framing, and be thereby rocked so as to take its catch end ¹² from
engagement with the sector arm (which is released), as represented in dotted lines
in Figure 18. Immediately the hooked or catch end has wiped over the sector, it is
then taken into its former position by the spring, ready to again engage with
the sector arm when the same is brought back by the volute spring after having
held the feed rolls during the required period.
Referring back to the giraffe or coil-former e, the same has upon its terminal
end or after part, a pitch gauge e, cousisting of a single helical projection, of a
slightly greater pitch than the giraffe, so as to give slightly greater tension to the
helix or coil, which travels forward and at the same time partakes of a rotatory
motion about its own axis, consequent upon the impelling force of the feed rolls
and the direction of motion taken in passing through the giraffe.
From the pitch gauge, the compound coil or double helix proceeds across a
gap c, and then takes upon a universally mounted threader i, which is a device
similar to the pitch gauge, only longer, and is adapted to keep the wire still on the
stretch and to direct the said wire as it issues from it, perfectly in a line with the
generatrix of the previously formed helix, which is, at the time lying between and
held by the fabric supporting rollers. The said threader, which has a mandril
lead passes through a hole, in an adjustment bracket 3, and is made fast
therein by a cross pin, and fits snugly within a hole, formed through a radial
adjustment plate, pivoted at ", to the movable cutter carrying plate, which is
conuerted to the cutter slide, by a set screw 10, which admits of the vertical
adjustment of the whole of the threader cognate parts referred to, relative to the
cutter, carried by the slide 2, which works within a' guide, carried by the
part of the general framing of the machine.
The threader carrying bracket is transverse-augularly and longitudinally
adjustable upon a stalk or peg 4, pivoted at 2, to the radial plate iº, and
being itself vertically adjustable with respect to the said plate. The adjustment
of the stalk 2, is affixed by a threaded plate "fast with it, and set screws is
A further general adjustment of the threader and the movable knife is effected by
connecting the framing, to the bed 6x, by the former having long slots 10 (best
seen in Figure 1) through which loose set pins 0, pass.
Thus, the threader Pas six adjustments, viz., a vertical adjustment relative to
the cutter slide, a radial adjustment relative to the said slide by means of the
plate, and curved slot, a horizontal, a transverse angular and a vertical
angular adjustments on or by means of the stalk, and the general adjustment
with respect to the bed of the machine by the framing ¿¹³.
is a fixed cutter adjustably secured to the framing of the machine, with
the cutting edge 22, coming in line with the upper movable cutter i, and on
the two coming together the helical coil between them is severed or cut off to
a dead length.
મે
The movable cutter is operated by a lever, fulcrumed at to the framing
at, and having a handle, for cutting off the wire if necessary by hand. To
this lever,
jointed a rod j³, having a screw-box adjustment, at its lower end
and jointedly connected to a rocking lever j, fulcrumed at 7, and having a roller
fore end, which is acted upon by the triangular wiper, of a cam j, keyed fast
to the main shaft 2. The said cam gives one cut-off movement to the lever for
every rotation of the shaft, which cut-off is timed to nip the wire at the
termination of each run of a coil.

page_text: The movable, cutter and its operating-lever are taken back to their non-acting
positions by a spring ", whilst the back movement of the said cutter is limited by
a stop
It will be understood that the threader and wire carried by it move together
with the knife, with the end of the pitch gauge constituting, as it were, the fulcrum.
k are a pair of fluted or channelled fabric-supporting rolls, turning within
cross-adjustable end bearings k, k³, and coupled together at their extreme ends
by toothed gear wheels k, and carried by a traversing slide k, working upon
rest or set-down edges of the bed 6x, which is longitudinally gapped at 610, to
admit of the dropping of the formed fabric onto a table 6, as set forth in
Figure 26.
The inward neck A, of the off-side supporting roller is extended at k, carrying
at its extremity a ratchet wheel k', having teeth equal in number to the grooves in
each of the supporting rollers, and constituting the means for giving an inter-
mittent part rotation to the said rollers on the termination of the run, and the
cutting off, of each helix. The said ratchet wheel 7, is operated by a pawl A,
carried by an arm k, hung or pivoted at its inner end upon the end of the
neck, and operated or rocked through the medium of a lifting rod kle and kept
in tooth by a spring ".
The lifting rod is worked by a hell cranked lever 1, upon the rollered end ¹³,
of which, the nose of a cam s, loose upon the shaft, and made twin. with
another cam loose upon the said shaft and with a bolt engages as hereafter
fully described for, making rigid connection between shaft and cams in ordinary
driving.
On each rotation of the shaft 3, the fabric supporting rolls are intermittently
rotated to the extent of one tooth on the ratchet wheel h, and one groove or
channel on their peripheries.
:
The fabric roller slide, is traversed upon its bed through the medium of a
rocking lever mounted upon a pin ki, adjustable in slots formed in a hanging
extension 6, of the bed and with the bulbous upper end 8, taking into a pocket .
on the underside of the slide. The other and lower end of the arm 15, is adjustably
connected to the outer end of a pull and push rod 20, whose inner end is
adjustably connected at 2, to a slotted pendulum arm, whose lower part 23,
carries an escapement consisting of an anchor-shaped arm, pivoted at 25, and
capable of reversing itself from one side to the other of the lower end of the lever
arm 2, by the roller, of the cam k", passing and re-passing the centre of the
escapement arm k24, whose tail end rests alteruately against stops 28, 29. The
cam, is loose on the shaft and is adjustably connected to the supporting-roller
rotating cam ¹.
It will thus be seen that as the roller of the cam k, comes round, it impinges
upon the inclined plane formed by one side of the latch, and slides down and past
the centre, and during ench traverse, it reciprocates the pull and push rod 20 in the
direction of the arrow Figure 4, and the slide carrying the fabric supporting rollers
in a forward direction (see dotted arrow Figure 4) and immediately the roller ³,
gets past the centre, and reaches the point then the latch tilts, and allows
the roller to pass, at the back of it and the cam moves now without any effect until
it comes round again onto the top of the latch in its new position, when the
pendulum arm k, is moved in the direction of the curved dotted arrow Figure 4,
and the slide taken back to its former position.
The extent of the movement of the slide is about one half the pitch of the
helices being coiled; which has the effect of separating the opposed ends of
the severed wire and changing the position of the termination of the helix held
by the supporting rolls, so that the next helix intercoiled shall not strike the end
of the one previously coiled on its rotation into the same, or to run on the top
or outside of the same without intercoiling and so preventing a miss-coil.
The swing of the pendulum arm A, is limited by adjustable stops, carried by
a fixed hanger 3, depending from the underside of the bed.

page_text: Thus, the cut-off precedes to a very limited extent, the rotation of the fabric
supporting rolls, which brings the last threaded helix lower than the axis of the
coil next the threader, and the traverse of the slide carrying the rollers is
subsequent to both the aforesaid movements and bring the generatrix of the
coil held into an adjacent and slightly overlapping position to admit of the inter-
coiling of the next helix.
Fixed along one side of the slide and running parallel with the near side
fabric-supporting roll, is a graduated scale m, markel off into inches, which is
read in conjunction with the scales m³, on the drum 20, which scales are equivalent
to the said inch scale m, on the bed. Now these divisions m³ are intersected by
ring lines m³, respectively corresponding to the different change wheels employe I
with the feed rolls. Thus, for instance, the drum is divided off into seven or any
other number of circumferential divisions, respectively corresponding to change
wheels employed in conjunction with the feed rolls and speeded to feel
respectively 65, 66, 67, 68, 69, 70 and 71 inches of helical wire (which are
the standard lengths of mattresses usually woven, to every rotation of the large
wheel and these circumferential ring scales are in turn divided off cross-wise
into 65, 66, 67, 68, 69, 70 and 71 spaces.
Supposing the feed rolls are speeded with a change wheel to run the coil
65 inches to every revolution of the large wheel and its axis, and supposing the
machine should, from any cause run wrong, then the machine is automatically
stopped by electrical means as hereinafter described, and the coil which is goije
wrong is severed by hand by operating the knives through the handle. The
change wheel is then thrown out of gear by the handle e, which also lifts the
ereels. Then by hand the feed rolls are rotated through the spindle 9%, and a coil
is fed along the scale on the bed to any point, say to 60 inches. The large wheel
is then turned by hand until cross division 60 on the 65 inch ring division marked 1,
brought under the pointer n, (in Figure 1) which is adjustable so as to bring its
point over any one of the ring divisions 1, 2, 3, 4, 5, 6 and 7. By so doing the
cams on the main shaft have been set or brought into the proper positions relative
to the ends of the several levers upon which they act, when the feed rolls are again
put into connection with the large wheel and the creels lowered onto their friction
pulleys by turning back the handle e The machine is then started, when the
rolls feed and the respective parts operate just in the same sequence as though no
cessation of work had occurred.
The mechanism so far described is designed to weave plain wire coiled fabric
only, without forming any cabling edges, body stiffening stripes, thickenings and
fillings.

I will now proceed to describe the means by which what is technically known as
cabling" or the introduction of strands or hollow strengthening stripes is effected,
that is, the running of helices screw-wise, one within the other.
Carried upon the offside end of the main shaft, is a bevel wheel o, intergearing
with a like bevel wheel o¹, made fast on an upright wormed shaft o, whose middle
part is cut with a worm. o; which intergears with the teeth of, of a cabling wheel oº,
runuing or mounted upon an axis of, carried by a hand lever o', fulcrumed at its
lower end at o, to the framing, and fitted at its upper end with a catch lever, oº,
for fixing the cable wheel into and out of gear with the worm, by a stud oo, on
the end of the catch lever taking into one or other of a pair of holes 1,613,
formed in a part of the framing 14. This cable wheel has 325 teeth upon its
periphery, corresponding to the number of component helices employed to make up
the greatest length of fabric capable of being woven un this particular machine,
and is speeded to make one 325th part of a rotation to every revolution of the main
axis and the said wheel (see Figure 8) carries a scale corresponding to the teeth
upon the periphery.
Cut all around the outer face of the wheel, and near the edge, is an annular
groove o, wherein the cranked and fout ends o", of face cabling or pause cams o¹³,

page_text: are fitted and secured by set pins o, which pass through holes 015, formed to
receive them in the flange o, of the wheel.
These face cams are placed around the cabling wheel, in positions corresponding
to the points in the fabric in which it is desired to form cables, which said came
constitute means for giving periods of rest to the fabric supporting rolis and their
traversing slide, without interfering with the feed rolls, coiler, cut-off and other
parts of the machine. Each cam forms a separate cable or strand in the body
fabric and occupies a space taken up by three teeth of the cabling wheel and
represents three helical feeds, and the spaces between the cams represent
corresponding extents of plain weaving.
The cabling wheel also has upon its face, a starting point o", and as a typical
illustration, proceeding round the wheel in the direction of the dotted arrow
(Figure 5) one cam (8) is placed against point 30 on the scale, another at 63
(marked 9) another at 95, (marked 10) and others at 100 (11) and 105 (12);
another at 140 (13) the next three at 205, (14), 210 (15) and 215 (16) and on the
latter of these is a projection o¹8, for ringing a bell to denote the width of fabric is
finished, The next cam (17) is for the commencement of the next length of
fabric and is a small one representing only two helices or wires and is interspaced
from the next cam by a distance the equivalent of one coil only, which is, as
hereinafter described, removed by the operator after a certain length of wire
fabric has been made and is then introduced into the said first cable or strand
of two helices, so as to make up a cable or strand having the full complement of
three helices and constituting the commencement of another mattress or breadth
of fabric, whereby waste of the joining up coil between two lengths of fabric is
prevented.
The cabling is performed by an arrangement and combination of parts as
follows:-
p is a hanging lever, swinging in the direction of the main shaft h², and
fulcrumed at p², to a bracket hanging from the underside of the bed, and with the
lower end gapped or formed into a loop p, fitted with two half trunnion clips or
straps p³, each trunnion working respectively within bearings, in the inside of
the loop and with the said strips or half clips taking upon a circumferentially
flanged bush p" threaded loose upon the main shaft h2, so as to admit of the bolt-
peg p, carried by the bush taking a parallel movement for entering the hole ³,
in the boss of the supporting-rolls reciprocating cam 27, which is twin coupled to
the other cam by a pin 4, taking through a radial slot and entering a hole
in the arm of the cam. By such means of adjustment, the relative positions of
the cams can be set for giving the rotation to the fabric, supporting rolls and the
reciprocation of the slide carrying them at the proper period.
The said bolt peg p, lies within a hole p', formed through a fixed boss or
collar ps, made fast to the shaft h2, so that during the rotation of the parts, the
end of the peg traces the face of the cam, and is directed into the hole 435, by
the lead, by which both the bush and the cams are locked together and to the
boss på, and the whole of the parts rotated together as one and with the shaft.
"
The cabling or forming of strands is effected by the freeing of the cams k¹, 27,
from the main shaft by the pushing back of the swinging arm p, as represented in
Figure 11, thereby taking the bolt p, out of position in the hole kas, by a link pl
jointed at one end to the extreme lower end of the said arm p, and at the other end
to a rocking lever or beam p³, fulcrumed at po, to a bracket p, on the framing,
and with the nose end p, of the short arm, wiping over one of the cabling cams o
on the face of the cabling wheel and so long as the said cam holds the bolt out of
its locking position, so long will the cams 1, 2, be thrown out of gear and the
supporting rolls remain in a state of rest, and after the cam, has passed out of the
range of the nose of the lever p, then the spring p13, pulls the parts back to their
normal positions, with the bolt p, engaging with the supporting roller rotating and
traversing cams, when the said rollers again take up the movements and plain
: :

page_text: weaving is resumed, until the next cam on the cabling wheel comes against the nose
of the lever again when the operation proceeds as before.
Immediately the first three cables of the second breadth of fabric have beeu
formed by those cams o¹³, which are numbered 17, 18 and 19, the cabling wheel is
disconnected from its worm by releasing the catch o° and pulling over the lever o',
so as to take the stud olo, of the said catch from the hole 6, into the hole 63. The
cable wheel is then turned on by hand until the projection o", is brought thirteen
graduations on the scale (or teeth of the wheel) beyond the starting point q, which
is done to allow for the cables woven in advance by the cams 17, 18 and 19. The
machine is continuously running during this momentary change of position of the
cabling wheel, which is either pushed on one or two points to allow for the plain.
spirals woven during the interim of the said turning on or no notice is taken of the
said spirals.
The completion of the weaving of a determined breadth of fabric is indicated to
the operative by the ringing of a bell through the nose o18, coming round and just
before it reaches the starting point lifting the pawl arm 9', which in turn raises the
jointed arm g, and lifts the rod q³, having mounted upon its end a frictional.
wheel, which is brought in contact with a like rotating frictional wheel os, at
the summit of the worm shaft o. Immediately contact is made, the spindle 93, is
rapidly revolved and swinging clapper arms at the summit of it, strike the bell q³,
hence the ringing.
In the event of a coil running wrong, the machine is provided with means for
stopping the same automatically by electrical agency.
Direct along and over the space between the fabric supporting rollers is a steel
bar, supported overhead by bracket arms, and insulated from the bed or
framing of the machine.
Connected to one end of this rod is a branch wire r³, connected to an insulated
L-shaped contact bar r, which is in electrical contact with the wire, of the
electric battery 6. The other wire r', of the battery is in connection with an
electrical magnet, and connected to the magnet is another wire ³, which is in
electrical connection with the general framing b, bx.
In front of the electric magnet is a catch, holding down a lever, fulcrumed
at, and normally forced upwards by a spring. The other end of the lever,
has a catch end, which engages with a shoulder 15, of a bell cranked hand
lever 16, jointed to the framing at 17, and normally kept in its holding position by
a spring. Connected with the said hand lever, is a long beam or lever 1,
turning about a fulcrum at 0, and with the inner end, resting under the catch
end; of the lever catch 16, which holds the stopping and starting lever in its
"starting" position.
Should a running helix go wroug, that is to say, run or be diverted out of its
assigned course, it strikes either against the L-shaped contact bar (in case it
runs wrong before reaching the threader) or against the bar r, over the fabric
supporting rolls when it runs out of truth during the intercoiling, by which
electrical connection is made between one wire of the battery through the rods r
or, and the other wire, contacting with the framing through the medium of the
helix or coil being threaded and the said framing, whereby the electrical circuit is
completed and the electro magnet made operative, which pulls back the catch 10,
and admits of the intermediate lever i, being rocked on its point by the spring 13
This removes the catch end 14, from engagement with the bell cranked lever,
which is in turn rocked by its spring, the long lever 1, turned so that its
nose, makes an upward movement and raises the hook end 17 of the holding
catch of the stopping lever from out of engagement with its holding shoulder
By these movements the stopping lever 13, is freed, drawn back by the coiled
spring 18 and the machine thereby stopped.
The mis-fed coil having been cut off and the machine restarted, the catch end f",
is then put into its holding position, and the other automatic stopping parts are

page_text: returned to their normal positions by the springs and of the parts
- and 7:15
Should the sector arm of the large wheel not act and the interweaving wire
over-race itself, its end impinges against a stop bar s, adjustable on a framing s',
and is thereby cambered or arched and is brought into contact with the bar r,
when the electrical circuit is instantly made and the machine stopped.
The fabric supporting rolls are kept parallel by-part back bearings, represented
in dotted lines in Figure 21.
It is understood that the words "length of fabric" throughout this Specification
"means the distance from one end of a woven coil to its other end, and 'that
"breadth" means the extent of fabric comprehended between the first helix passed
into the supporting rollers and the helix or coil last woven.
