Improvements in Machines for Making Coiled Wire Fabric.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention to be as follows:--
This invention relates to machines for making wire coiled fabric and comprises
the improvements hereinafter set forth.
In the Specification of a prior Patent No. 15831 A.D. 1892 there is described a
machine for coiling one wire at a time. An important feature of the present
invention is that two or more wires are coiled and woven into fabric simultaneously.
The wires are fed to two or more coilers by friction wheels or rollers which are
automatically separated to stop the feed when the proper amount of wire has been
fed to form one length of coil in the fabric, and then the various devices for cutting
off the wire and changing the position of the fabric are brought into operation,
after which the feed rollers are allowed to close to feed another length of wire to
form another coil, whereupon the operations are repeated. The feed wheels or
rollers are controlled by a cam which is loose upon its shaft and is moved inter-
mittently by lugs on a suitable chain, said chain being driven through a friction
cone and wheel. By moving the wheel across the face of the cone the speed of
the chain can be adjusted as required. Said mode of driving this chain and of
varying the speed thereof constitutes an important feature of this invention. The
speed at which said chain travels determines the length of wire which is run through
the coilers before being cut off. The means for separating the friction feed rollers
to stop the feed consist of a rocking shaft which is operated by the cam before
mentioned; said shaft is flattened at the end which projects under the spindle or
bearing of the upper roller so that when it is rocked by the cam the upper feed
roller is thereby raised and when it is rocked back to its normal position the upper
feed roller is brought back into contact with the lower one by a spring. The
operating cam may be made adjustable, and is also provided with a spring locking
catch or equivalent device that engages the lug on the chain belt and locks the
cam to the belt, when the lugs on the belt engage with the cam, to prevent the cam
overrunning the belt. The cutting-off knife is operated by a cam which has a
period of rest whereby the knife after it has severed the wires is retained for a
period over the wire holes and prevents the rear ends of the wires in the fabric
re-entering said holes or becoming entangled with the ends projecting from the
coilers when the fabric is moved backwaid or forward to bring it into position
for receiving the next coil.
The woven fabric passes over suitable supporting rollers or beams and is weighted
to cause it when released to feed upward into proper position for receiving the
next coil.
To provide for inserting more than the usual number of coils where required I
provide a star wheel which is driven intermittently by the lugs on the above
mentioned chain belt. Said star wheel controls another chain belt having similar
lugs adjustably fixed thereon. Said lugs control a clutch lever in such mauner
that when in engagement with said lever the clutch is moved and held out of gear
so long as the lug is in engagement with the clutch lever, and thereby the feeding
of the fabric is stopped until the proper number of coils is inserted, whereupon the

page_text: lug is moved out of engagement with the clutch lever, and the feeding of the fabric
then proceeds as before.
Means are provided to secure the proper engagement of the chain belt and cam
shaft when the fabric is to be fed forward again.
The fabric is held in place by two bars connected together and each having
horizontal pins projecting through the coils so as to hold the fabric in proper
position; said series of pins engage alternately with the coils and their
movement is controlled by an eccentric or cam which is driven by the aforesaid
chain belt.
Moreover I provide a bar having a V-shaped edge which can be pressed against
the fabric between two coils by a cam and lever arrangement. Said bar serves to
hold the fabric while the pins are changing their position and is then released to
allow the fabric to pull up against the last inserted pins. Said bar is preferably
carried loosely on one set of the horizontal pins.
A stop motion is provided to stop the machine when the coil is prevented from
running properly or is caught on the reels, and also when the wire is used up.
This motion comprises a lever or arm and guide roller over which the wire runs in
combination with a spring controlled belt-shifter that is released when the said
lever or arm is raised by the tension in the wire.
Another stop motion is provided for stopping the machine when the wire doubles
or is prevented from running. This motion consists of a hammer loosely resting
against or near the wire as it leaves the coiler and which is thrown over and
strikes a pin in the circumstances mentioned thereby releasing a spring-controlled
belt shifter.
I provide a roller worked by a ratchet and pawl for taking up the slack fabric.
For adjusting the coil to any desired pitch provide an adjustable piece or guide
through or around which the wire extends. Said piece or guide is preferably
placed inside the sleeve of the coiler..
Means are also provided for subjecting the wires to tension while being introduced
into the last coil or coils of the fabric.

Improvements in Machines for Making Coiled Wire Fabric.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 machines for making coiled wire fabric and has for its
object to further improve machines of the kind or class described in the Specifi-
cation of prior British Letters Patent No. 15831 A.D. 1892. In the said prior
Specification there is described a machine which coils one wire at a time and weaves
the coils into fabric.
An important feature of the present invention relates to the provision of means
whereby two or more wires are coiled and woven into fabric simultaneously, and
hence by this improvement fabrics which have two or more wires in each coil can
be produced with the same rapidity as can single wire fabrics in the machine
described in the said prior Specification. Since multiple wire fabrics are now
more common than single wire fabrics it is obvious that this feature of the present
invention is very important.
The said invention comprises various improvements as will be hereinafter
explained.

Figure 21 is a view similar to Figure 20 but showing the adjustable part of the

Like reference letters denote corresponding parts in all the figures of the
drawings.
A is the frame of the machine supported on suitable legs not shown in the
drawings. At one end of the machine which may be termed the head is provided
a pair of rollers B, B for feeding the wire to the coilers C two of which are shown
side by side for coiling and feeding into the fabric two wires at the same time.
Said feed-rollers are mounted respectively on upper and lower parallel shafts b, b
sec Figures 1 and 5 which are supported in standards b', 6' and are connected at one
end by gear wheels 62 Figure 1. The lower of baid shafts is the driver and is
furnished with fast and loose pulleys b³, on which the driving belt 6° works. The
bearing-block of the upper shaft b at that end nearest the feed-roll is movable
up and down in the standard to admit of the feed-rollers being separated when
feeding is to cease. Said bearing-block is forced downwards by a spring 6,
Figures 5 and 6, the pressure of which can be regulated by a screw 6' and is raised

page_text: when required by means that will be presently described. D, Figure 1, is another
shaft mounted in bearings at the head of the machine and placed at an angle with
the shafts b, b. D₁ is a cone friction-drum fixed on said shaft D and engaging with
a friction driving wheel D³ carried by the lower driving shaft b. Said wheel D'
is connected by a feather key or equivalent means to its shaft so that while being
capable of sliding thereon it must turn therewith. E Figures 1 and 7, is a chain
wheel fixed to or formed with a sleeve loosely mounted on the shaft D but geared
therewith by a system of wheels d similar to the back gear wheels of a lathe.
The speed of the chain wheel is less than that of the shaft 1), and this speed can
be regulated to suit requirements by sliding the driving wheel D' along its shaft
nearer to or further from the base of the cone D'. By this means the speed of all
the moving parts of the machine can be adjusted relatively to that of the feed-rolls,
and the length of the woven fabric, that is to say, the length of each wire fed into
the machine before being cut off thereby adjusted.
The chain E which works on the wheel E and communicates motion to various
other parts of the machine is provided with lugs or brackets E* secured thereto at
intervals for a purpose hereinafter explained. Loosely mounted on the shaft D
by the side of the wheel E is a cam disc F which controls the feeding of the wire
to the coilers as follows, that is to say, the said cam disc is constructed with ears F1
formed or fixed on its periphery and adapted to be engaged and moved by the lugs
or brackets E of the chain E' as the said brackets successively arrive at the cam.
Two such ears F¹ are provided in the cam disc illustrated, these being placed
diametrically opposite each other, and each lug or bracket E2 of the chain on
engaging with either ear operates to turn the cam through half a revolution and
then automatically disengage itself from said ear as will be readily seen from
Figure 7 of the drawings. The cam proper is formed on the side of the disc F
and has in its periphery two diametrically opposed depressions F2, see Figure 7.
In each position of rest of the cam there rests in one of the depressions F' a roller G¹
mounted on the end of an arm or lever G the stem or axis G2 of which see Figure 6
is carried by and can turn in a bearing 68 Figures 1 and 6 formed on the standard ¹
adjoining the feed-rolls. The inner end of the stem G2 is partially cut away to
form a flat G³ see Figures 5 and 6 which flat part projects underneath the bearing-
block of the upper feed-roller shaft b. As the cam disc F is intermittently
rotated by the chain E', the roller G¹ carried by the arm or lever G is alternately
raised out of and then allowed to fall into the depressions F2 of the cam thereby
causing the stem or axis G2 of the said arm to rock in its bearing. By reason of
the flat G³ formed at the inner end of the axis, this rocking movement has the
effect of raising and lowering the bearing-block 6 of the upper shaft b. By this
means the feed-rollers are forcibly separated and then allowed to come together
again and thus the feeding of the wue is interrupted at regular intervals to allow
of the wires being severed and various changes take place in the different parts of
the machine as will be hereinafter explained before the feeding commences again
to form the next coil. While the roller G' is raised out of the depressions F
there would be some risk of the cam being carried round by the.friction of the
shaft D which shaft it will be remembered travels much more quickly than does the
chain wheel E. To prevent such an occurrence which would result in the rolls not
feeding at the proper time, provision is made as follows, that is to say, the cam
disc whilst being turned by the chain is locked thereto by means of a spring F
one such spring being mounted on the cam disc immediately in rear of each lug or
ear F. Before engaging with either ear F¹ each lug E must first depress and
pass over the corresponding spring F³ which spring then rises up behind the lug
and engages with the rear edge thereof while the forward edge of the lug is in
contact with the car F¹. By this means the cam disc is prevented from overrunning
the chain. The lug E' is able, by reason of its more or less radial movement with
respect to the cam as the chain leaves the cam disc, to disengage itself from the
ear F and spring F3 when at the lower side of the wheel.
The duplicate reels for supporting the wire for forming the fabric are hung from

page_text: the framework of the machine at a convenient part thereof. They are constructed
substantially as described in the Specification of former British Letters Patent
No. 11461 dated 10 June 1893. H, H are the wires coming from said reels. Said
wires are guided by pulleys HH' and pass through the feed-rollers B, B to the
coilers C whence they are projected in the form of coils or spirals and enter a
receiver h hereinafter described.
The coilers are shown clearly in Figures 17 to 21. The wires H H coming from
the feed-rolleis pass through a grooved guide el which is provided with a removable
top plate c² and with tension devices which can be regulated by screws c³, e³ for
adjusting the tension on the wires. The wires next pass around the coiling barrels
proper which are grooved spirally as clearly shown in Figures 19 to 21 and are
surrounded by loose sleeves c³, c that while free to rotate cannot move end wise.
The barrel of each coiler is fixed in place by a pinching screw but can be released
to allow of adjustment either axially or rotary as may be required for setting the coils
coming from adjacent coilers parallel, or for taking up wear or other purpose. The
wire is delivered to the groove in the barrel at the proper angle to pass into said
groove without being bent. At the delivery end of each barrel c is a short loose
continuation thereof which is formed with a spiral groove much wider than that
in the barrel ct. This part c is secured to a handle or arm e' that passes through
a hole in a pin c which can be moved along a slot c in a stationary plate c¹ and
secured in any desired position in said slot by a thumb-nut c¹. By loosening said
nut and moving the pin along said slot the piece can be turned about its axis
and by this means the edge c¹ of its spiral groove can be made to press more or
less hard upon the wire coils issuing from the groove in the coiler barrel and
thereby alter the pitch of said coils. For example in Figure 21 the part c¹ is
shown adjusted to press on the coils and thus produce a longer pitch than is the
case in Figure 20 where the part e¹ does not press on the coils. The sleeves c³, ca
are rotated by the pressure of the wires thereon as the latter pass through the
spiral grooves of the coilers.
A
The receiver into which the coils enter on leaving the coiler consists of a
rectangular tube extending the full length of the machine and having an open top.
This receiver is mounted upon suitable stationary supports upon the frame of the
machine and is located in line with the coilers so that as the spirals leave the
coilers they enter said receiver and pass along therein. Arranged in this receiver
is a plate Figures 3 and 4 capable of sliding longitudinally therein as hereinafter
explained. Said plate is provided with a series of evenly spaced vertical pins /³
against which the coils bear as they pass through the receiver. The pins are
spaced somewhat further apart than the pitch of the spirals, and the first pin is so
placed with reference to the coilers that when the coils pass into the receiver the
forward ends thereof come into contact with the said first pin on the side thereof
farthest from the coilers, and as they pass this pin considerable pressure is exerted
by the pin on the wires whereby the coils are stretched or put into tension.
similar action occurs as the ends of the coils strike the next pin thus putting
additional tension on the wires and so on throughout the receiver, and as the wie
coils strike each pin in succession the pressure on the preceding pin is released:
thus the tension or pull is exerted between the coiler and the pin at the advancing
end of the coils while the coils are practically free from the other pins. Owing to
this feature of passing the coils into the receiver under tension the said coils can
be formed successfully of almost any length. After each pair of coils has been
passed the proper distance into the receiver and interlocked with the last preceding
coils in the fabric, the wires are severed by means hereinafter described, and then
the plate is moved longitudinally a distance equal to half the pitch of the coils
for the purpose of moving the coils just formed into proper position for receiving
the next or incoming coils. The means provided for moving the plate h' are as
follow. The chain E is supported at the extreme end of the mach ne furthest
from the head by a chain wheel I which is mounted loosely on a shift carried in
suitable bearing brackets Jo. Also mounted loosely on the shaft by the side of

page_text: the wheel I is a boss J' forming one part of a clutch which is normally geared with
the other part of the clutch J which is connected with the shaft J by a feather
key or its equivalent so that it cannot turn on the shaft but can slide axially
thereon. The part J of the clutch is finished with a pair of diametrically
opposite radially projecting fingers Js which are adapted to be engaged by the
lugs E2 of the chain E, and when so engaged to be carried round by the said lugs
thus rotating the clutch and consequently the shaft J when the two parts of the
clutch are in gear but not otherwise. Each lug E of the chain tuins the clutch
through half a revolution and consequently always leaves one of the pins or
fingers Jin position to be acted upon by the next lug. Fixed on the shaft J is a
bevel wheel K that is only furnished with teeth on a part of its circumference.
This wheel is adapted to gear with a bevel wheel K see Figure 1 also furnished
with teeth on a portion only of its circumference. The said wheel K drives
through its shaft K, and ordinary bevel wheels K³, K³, a vertical spindle K* at
the lower end of which is an eccentric K³, see Figure 10, or like device which is
connected by the link K with the plate of the receiver h. It will be seen
therefore from the above description that the said eccentric K³ or equivalent device
will be rotated at regular intervals by the engagement of the successive lugs of
the chain E with the fingers J³ of the clutch J, and by this means the plate /
will be moved intermittently first in one direction and then in the other direction
the proper distance in the receiver h. The fabric is thus adjusted, after the
insertion of each set of coils thereinto, to the proper position for receiving the
next coil.
In order to allow of the insertion of several sets of coils into the fabric at any
desired place to secure increased strength, provision is made as follows, that is to
say, the part 2 of the clutch above described is coupled to the forked upper end
of one arm of a bell-crank lever L which is pivoted at L' to a bracket L carried
by the frame of the machine. The other arin of the said lever is depressed by a
spring L2 which normally maintains the clutch in gear. M is a star wheel which
is mounted loosely on a vertical spindle M' and connected with a chain wheel M²
on which works an endless chain M³. Said chain passes round another chain
wheel M and is furnished at suitable intervals with removable and adjustable
lugs Ms.
The said star wheel M is rotated intermittently by the lugs E2 of the
chain as the said lugs successively pass the said wheel. By this means the
chain M³ is moved intermittently, and the lugs M thereon are brought successively
at definite intervals of time underneath the horizontal arm of the bell crank lever L,
and they remain thereunder for a definite interval of time. Each lug so passing
under the horizontal arm of the lever I ra.ses said arm and thereby throws the
clutch out of gear thus arresting the shaft J and all the mechanism which is
operated by said shaft whereby the fabric is maintained in the same position while
another set of coils is introduced thereinto. The addition of sets of coils at the
same place in the fabric continues until by the movement of the star wheel M the
lug of the chain M³ is withdrawn from underneath the lever L whereupon the clutch
is immediately put into gear again by the spring L2 and the shaft J once more
operated to effect the changes in the position of the fabric, as will now be
explained.
This
For the purpose of securely holding the final coils in the receiver while the
incoming coils are being inserted I provide a plate N Figures 1, 3 and 4 mounted
upon the receiver so as to be capable of sliding thereupon. The said plate is
adapted to be moved forward to partially cover the open top of the receiver.
plate which extends the whole length of the receiver is formed with a bevelled
forward edge as clearly shown in Figure 4 and is adapted to project into the space
between the last series of coils and the next to the last series, and thus hold the
said last series of coils of the fabric rigidly in position in the receiver for the incoming
coils to be interlocked therewith. This plate is connected by links N' to cranks N'
fixed on a rock shaft N³ carried in suitable bearings. N Figures 1 and 2 is an arm
or lever fixed to one end of said rock shaft and coupled to a link N' which is

page_text: furnished at its upper end with an antifriction bowl Nº that rests on a cam N' fixed
on the shaft J. The arm N is held down by a spring N° secured to said arm and
to the frame of the machine. The cum N shown more clearly in Figure 8 is so
shaped that at the proper time it operates to raise the arm N and thereby to rock
the shaft N and push the plate N into contact with the fabric, to hold said fabric
for the purpose above stated, and then releases said arm N' again at the proper
time to allow the plate N to be withdrawn by the spring No, whereupon the fabric
is fed upward.
Besides the retaining plate N just described, and the vertical pins /², there is
provided for holding the fabric a double series of horizontal pins O Figures 1 and 3
which are projected alternately through the coils for a purpose that will be
explained. Said pins are carried by the two upwardly projecting sides of a frame P
see Figure 3 that is situated beneath the receiver h and extends the whole length
thereof. Said frame P is supported by the framework of the machine in such a
manner that it can slide transversely for a limited distance. It is reciprocated by
means of crank arms P¹ fixed on a rocking shaft P2, said crank arms being forked
or recessed at their upper ends to engage with downwardly projecting lugs P³
formed on or fixed to the underside of the frame P. On the end of said rock-
shaft P is fixed an arm P4 Figures 1 and 2 which arm is coupled by a link P³ to
the pin P of a crank fixed on the shaft K' before referred to. The shatt P is by
this means rocked intermittently, and at the proper moment changes the positions
of the horizontal pins with respect to the fabric. The pins on one side the frame I'
engage and lock the last series of coils of the fabric when the frame is at one
extreme of its movement, and those on the other side engage and lock the fabric
when the frame is at the other extreme of its movement. After one set of pins has
been withdrawn and the other set introduced into the fabric the fabric is released
and is permitted to be moved upwards a distance equal to the diameter of the coils
thereby bringing the final coils into such a position in the receiver that the next or
incoming coils will engage therewith. The pins on one side the frame slide freely
through the plate N above described and move independently of said plate. The
eccentric for sliding the fabric longitudinally in the receiver is preferably so timed
that it moves the fabric at the instant when both sets of horizontal pins are
disengaged from the fabric, that is to say, while the fabric is prevented from moving
upwardly only by the plate N, which plate however does not prevent the fabric
from sliding longitudinally in the receiver. After the fabric has been moved a
distance equal to half the pitch of the coils, the other set of horizontal pins are
introduced and then the plate N is withdrawn whereupon the fabric moves upward
a distance equal to the diameter of the coils and is then arrested by the horizontal
pins last introduced. These movements are repeated after each coil is
introduced.
The woven fabric in passing upward out of the receiver slides off the vertical
pins and passes over a curved beam Q and then over a rotating beam or
windlass R which has studs or pins projecting from its surface to prevent the fabric
slipping thereon. The fabric hangs down between the two beams Q and R as shewn
in Figure 2 and is weighted by a roller Q. It is this weight that keeps the fabric
tight and draws the same off the pins when released by the plate N above
described. The beam or windlass R is supported in bearings in brackets R' and has
secured to one end of its spindle a ratchet wheel R with which engages a pawl R³
pivoted on the rocking arm P. When said arm is rocked as above described the
pawl R³ operates to turn the beam R through a suitable angle and thus intermittently
feeds the fabric forward. R' is another pawl engaging with the lower side of the
ratchet wheel R to prevent same bei: g turned back. Said pawl is pivoted at R' to
the frame of the machine, and is loaded at its tail end to keep the forward end
thereof in engagement with the ratchet wheel.
In lieu of driving the arm P by a crank as above described, I sometimes drive
it by means of a cam groove p see Figure 9 with which an antifriction roller or
pin p¹ carried by the arm engages. By this means the horizontal pins are so

page_text: moved that a pause is ensured just as one set of pins is withdrawn from the coils in
the fabric and before the other set is introduced. Time is thus allowed for the
fabric to move up as above described.
The cutting-off knife S shown in Figure 1 and on a larger scale in Figures 12
and 13 is pivoted at S¹ and is operated or swung to and fro by a cam S Figures 1
and 11 through a rod S3 which is adjustably secured at S to the tail end of the
knife, and carries near its other end a roller $5 which works in the groove of the
cam S. The coils coming from the coilers gradually come together and then
coil around a stud T and finally emerge through an opening T¹ over which opening
the knife blade is oscillated and against the upper edge of which the shearing is
effected.
The cam S2 is constructed to afford a period of rest just after each shearing is
effected, and the knife blade is retained during this period over the opening T¹ so
that the rear ends of the coils that are in the fabric cannot be projected back into
said opening or become entangled with the ends of the coils projecting from the
coilers.
The stop-motion for stopping the machine when the wires double or do not run
properly comprises a hammer U Figures 1 and 15 which is pivoted at its lower end
to the frame of the machine and rests lightly in a slightly inclined position see
Figure 15 against the stud T and also the wire coils between the coilers and the
said stud T. Should the said hammer be pushed back a little beyond the vertical
position by reason of the wires doubling or running crooked for example it inime-
diately overbalances and falls and strikes a pin U as indicated by dotted lines in
Figure 15 driving sand pin downwards and forcing a lever U2 on which said pin
rests into the position shown by dotted lines in Figure 14. The lever U2 is pivoted
at U to the frame of the machine and is coupled by a link U to the lower end of
a lever U which is pivoted at U to the frame of the machine and the upper end
of which engages a pin U7 fixed in the belt shipper rod U8. U is a spring extended
between the lower end of the lever Us and a fixed hook U.; said spring when free
to act, pulls the lever U³ and thereby slides the belt shipper so as to throw the
driving belt Figure 1 from the fast to the loose pulley. Such action of the
spring is restrained however so long as the lever U2 is raised as shown in full lines in
Figure 14 by reason of the fact that the said lever and link U' form in that position
an elbow joint which is bent slightly upwards so that the pull of the spring tends
to force the lever U2 upwards against the frame of the machine. Immediately
however, the lever U is driven downwards thereby first straightening and then
bending the elbow joint in the other direction the pull of the spring tends to turn
the lever U2 downwards which it is quite free to do and so moves the belt as above
described.
Another stop-motion which operates to stop the machine should the wires coming
from the reels become stretched too tight is shown in Figure 16. The wires H are
conducted around a guide roller V which is mounted on an arm V₁ pivoted at V
Connected with the arm V' is another arm V3 which projects above the lever U
between said level and the frame of the machine. Should the wires be stretched
too tight the roller V is drawn upwards thereby raising the arm V and depressing
the arm V3. The lever U2 is thus depressed with the effect of throwing the driving
belt on the loose pulley, and stopping the machine as above described.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me by
my foreign correspondents, I declare that what I claim is-

speed of the rollers which feed the wire to the coilers, for the purpose specified.
2. The means for regulating the specd of the various parts of the machine with
respect to the speed of the rollers for feeding the wire, comprising the cond

purpose
6. A coiler comprising two barrels c¹, c both of which are provided with spiral
