Improvements in and relating to Machines for the Manufacture of
Endless Wire Cloth or Bands Used in Paper Manufacture.
I, PAUL TOURASSE of No. 95 Boulevard Beaumarchais, Paris, in the Republic
of France, Manufacturer of Wire Cloth, do hereby declare the nature of this inven-
tion to be as follows:-
This my invention relates to improvements in machines for making endless wire
cloth or bands, such as are used in the manufacture of paper, and the object of
my invention is to make such endless wire cloth or bands by the means hereinafter
described.
My improved machine is constructed to form the wire of which said wire cloth
is to be made, into a series of spirals of suitable length and, dimensions. Each
spiral is automatically interlaced during its formation with the spiral previously
completed, in the manner hereinafter described.
In carrying out my invention I provide the upper portion of a suitably con-
structed frame with a sliding plate capable of receiving longitudinal movement by
means of a cam. To said sliding plate I attach two bearings, one of which is fixedly
attached, whereas the other is capable of receiving endwise movement in order that
it may be brought closer to or moved further from said fixed bearing.
Said bearings are adapted to receive suitable shafts, each of which is provided
with a friction-disc, which friction-dises engage with one another, on the movable
bearing being brought sufficiently close to the fixed one, thereby transmitting any
motion received by one shaft on to the other.
I find it advantageous that said shafts and their attachments hereinafter referred
to, should revolve at a great speed and consequently the shaft. which is situated in
the movable bearing is preferably provided with a small pulley which receives
motion from a relatively large pulley by means of a belt. Said large pulley is
suitably supported at a convenient part of the frame and is adapted to receive
motion by suitable means from any convenient motor.
The shaft which is situated in the fixed bearing is provided or adapted at the
opposite end to that at which the friction-disc is situated, with a suitable
chuck, capable of gripping one end of a steel rod for the purpose of imparting
motion thereto.
'The loose end of said steel rod is adapted to pass within a worm of suitable
construction and dimensions which is removably fixed at each end to suitable
bearings attached to the sliding plate referred to and also adapted to receive
endwise motion.
The frame is also provided with a suitable bracket for the purpose of
supporting a spool around which the wire used in making the wire cloth, has
been wound.
For the purpose of forming the spirals referred to the steel rod upon which
the worm is situated, is set in motion and the end of the wire is attached thereto,
which causes said wire to twist round said rod and by means of the aforesaid, worm,
at the same time to travel forward, thus forming a spiral.
Said spiral is permitted to travel forward until a sufficient length thereof projects
through a support situated on the sliding plate, when the machine is stopped and
the length of spiral cut off. Said spiral is now moved a little to one side on to
a suitable bench, and is there held fast by spring clips or other suitable means, so
that on the machine being again set in motion, the new or second spiral is formed
and interlaces as it travels forward with each thread of the fixed or first spiral.

page_text: The machine is again stopped, said second spiral is cut off in a similar manner to
the first, the first spiral is removed and the second is fixed in its place when the
machine is again set in motion and a third spiral caused to interlace with the
second, and so on, the number of spirals depending upon the length of wire cloth
to be made. When a sufficient number of spirals have been formed and joined in
the manner described, the one last formed and the one first formed are so placed
on the machine that a new spiral on being formed in the usual way interlaces with
both of said spirals and thereby forms one endless band of wire cloth whose width
is that of the length of the spirals. The edges of said endless band may be
woven or interlaced in a similar manner to that above described and the said band
will then be complete.
The spool from which the wire is unwound, is preferably provided with a
suitable brake so as to keep the wire taut on the steel rod; and I wish it also to
be understood that the dimensions of the spiral, other than its length, may be
altered by removing the worm and steel rod which shape the spiral and substituting
others of suitable dimensions and configuration as may be required.
For the purpose of driving more than one machine from the one driving pulley,
each such machine is provided with a driving shaft adapted by means of suitable
couplings to be coupled together; and for the purpose of stopping all machines
simultaneously I provide the main shaft upon which the driving pulley. is fixed and
the first driving shaft, with a suitable friction clutch adapted to be put into or out
of gear by suitable levers.

Improvements in and relating to Machines for the Manufacture of
Endless Wire Cloth or Bands Used in Paper Manufacture.
I, PAUL TOURASSE of No. 95 Boulevard Beaumarchais, Paris, in the Republic
of France, Manufacturer of Wire Cloth, do hereby declare the nature of this inven-
tion and in what mauner the same is to be performed, to be particularly described
and ascertained in and by the following statement:—
This my invention relates to improvements in machines for making endless wire
cloth or bands, such as are used in the manufacture of paper, and the object of my
invention is to make such endless wire cloth or bands by the means hereinafter
described.
My improved machine is constructed to form the wire of which said wire cloth
is to be made, into a series of spirals of suitable length and dimensions. Each
spiral is automatically interlaced during its formation with the spiral previously
completed, in the manner hereinafter described.
In order that my invention may be readily understood, reference is made to the
accompanying drawings wherein like letters indicate corresponding parts throughout
the several figures and in which :-
Figure 1, represents my invention in side elevation.
Figure 2 represents an end elevation thereof.
Figure 3, represents a transverse section showing the manner in which the wire
cloth is supported during manufacture.
Figure 4 represents on an enlarged scale, the mechanism which I employ to
produce the spirals.
Figure 5, represents a longitudinal section of the framing which supports the
mechanism shown in Figure 4.
Figure 6 represents on an enlarged scale the formation of a spiral.
In carrying out my invention I construct a suitable frame E which is adapted to
support all the mechanism of the machine. Supported in suitable bearings with

page_text: which the frame E is provided, I mount a shaft B which receives rotary motion
from any desired source by means of a belt A. Said shaft B is provided at its
opposite end with a coupling flange F which corresponds to a coupling flange on the
shaft of the next machine, the whole being arranged in such a manner that when
the said flanges F are coupled or bolted together, several of these machines can be
driven by the belt A. For the purpose of stopping all the machines which are
driven by the shaft B, I provide said shaft B with a suitable friction clutch C
which may be operated by a lever C' in the usual manner.
The shaft B has also mounted on it a comparatively large pulley D, which, by
means of a belt D', drives a comparatively small pulley D" which latter is mounted
on the end of a shaft H which is supported in suitable bearings I l'. It is essential
to the efficient working of the machine that the shaft H shall revolve at a high rate of
speed, hence the difference in the sizes of pulleys D D. The bearings II' are
supported by a sliding plate J, which sliding plate is adapted to receive longitudinal
movement by means of a cam K' which is provided with a stud K". Said stud K"
enters into a suitable socket k formed in the sliding plate J and motion is imparted
to the whole by means of a handle K which is fixed to the axis K¹ of the cam K¹.
As has been already stated, the clutch C is provided for the purpose of
enabling all the machines which are coupled to the shaft B being stopped, but in
order that any one of the machines may be stopped, the shaft H of each machine
is.made of two parts H H. The part H' which is situated on the left hand side,
is provided at its right hand end with a friction disc H 1', which is adapter to be put
into frictional engagement with a corresponding friction disc H2 mounted on the
left hand end of the part H as will be hereinafter described. The bearing I is
provided on its under side with a plate N¹ which is adapted to fit between guide
plates N fixed to the sliding plate J, the arrangement being such that the bearing
may receive any necessary longitudinal movement by means of a lever M which is
pivoted at M' and the short end m of which lever M enters an aperture m¹ with
which the plate N' is formed. The opposite end of the lever M is formed with an
elongated aperture M" with which a pin on the lever L engages, so that the
bearing I may be moved in either direction by correspondingly moving the lever L,
and thereby the friction discs H and H2 may be moved into or out of engagement.
After the machine has been in motion, if the friction discs be suddenly thrown out
of engagement as described, the shaft H and its attached friction disc H², would
normally continue to revolve for some time by reason of their stored up energy. To
prevent this, I pivotally attach a brake or the like O at O" which brake is
normally pushed against said friction disc H2 and thereby causes it to stop and in
order to keep said brake out of contact with its disc during the time that both discs
are in engagement, I fix a finger or the like P to the plate N' so that, when the
said plate N¹ is moved towards the bearing I¹ the finger P will push the brake O
out of contact with the disc H*.
The shaft H is formed or provided at its right hand end with a suitable chuck h
which is adapted to grip the preferably conical end of a steel rod h¹. The said
rod is adapted to be passed through a screw thread worm or the like " which is
removably fixed at each end to suitable bearings Q Q¹ mounted on a plate J' which
is suitably supported by the plate J. The distance between the worm " and the
chuck h may be regulated by means of set screws J".
The wire S from which the wire cloth is to be made, is wound on a suitable
bobbin or reel R which is provided with a brake R' from which reel R said wire
passes over a pulley r with which the suitably mounted guide R" is provided, by
means of which guide R and pulley the wire S may receive any necessary
inclination. The wire S is next wound for a short distance spirally around the
rod h¹ and between the threads of the worm h" so that the said worm and the
wire S will form between the bearings Q Q two spirals in juxtaposition. When
the steel rod is caused to revolve the wire S will be twisted round with it as it
automatically unwinds from the reel R, thereby forming a spiral which will be
caused to travel forward through the bearing Q₁on account of the worm " being

page_text: held stationary in its bearings. After having passed through the bearing Q₁ the
spiral S is guided by a suitable support T through which it is allowed to pass until
a sufficient length thereof projects beyond said support. The rod is stopped as
above described and the projecting spiral is cut off in any suitable manner a little
to the right of the support T. The cut off spiral is next placed upon a bench or
the like V upon which it is held by means of a series of grips V pivotally
mounted, on a common rod W in such a manner that the whole of said grips Vi
may be manipulated simultaneously by manipulating the said rod W. The
ends V of the grips being pushed by means of a corresponding series of
springs Vin such a manner the ends V₁ grip the spiral S. Said spiral S is
arranged and held in such a position on the bench V, that when the rod ' is again
set in motion, the right hand end of the spiral being formed, will interlace with
each of the threads of the spiral already formed so that when a sufficient length of
the second spiral has been formed, and cut off as the first, the two spirals will
form one band in which each thread of the one spiral will be interlocked with the
corresponding thread of the other spiral. The first spiral is now released and the
second spiral fixed upon the bench V when a third spiral is formed as described,
being caused to interlace with the second spiral and then cut off as before, and so
on, auy desired number of spiral lengths being in this manner joined together to
form a band whose width is equal to the length of the spirals. For the purpose of
supporting the length of wire cloth during manufacture, I provide a drum U to
which the end of said cloth may be attached in any suitable manner, and upon
which drum U the wire cloth is wound as it is made, in the following manner.
Said drum is provided preferably at each end, with a worm-wheel U₁ which is in
engagement with a worm Ul adapted to be revolved in any desired direction by
means of a crank or equivalent Uit When a sufficient length of wire cloth has
been made, the spiral first made and the spiral last made are fixed on the bench V
in such a position that on a new spiral. being formed in the usual way, said new
spiral interlaces with both the.first and last spirals referred to and thereby the ends
of said wire cloth are joined together, forming an endless band without seam
specially adapted to be used in paper manufacture.
A machine as above described, is adapted to manufacture endless wire cloth or
bands of greater or less fineness as the "pitch" of the spiral depends upon and
corresponds with the pitch of the worm " which worm may be removed from the
bearings. QQ and a worm of different "pitch" inserted. The internal diameter
of the spirals depends upon the diameter of the rod.h" which also may be removed
from the chuck and another rod of greater or less diameter inserted.
According to the thickness of the wire S employed in the manufacture of the
wire cloth, it is found desirable that the distance between the guide T and bearing Q
shall be regulated, which may be accomplished by means of the handle K and
attached mechanism as hereinbefore described. I also prefer to affix or provide a
table or bench X which is adapted to receive the necessary tools and accessories.
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 :-
An improved machine for the manufacture of endless wire cloth or bands used in
paper manufacture, having a suitable frame-E-adapted to carry the mechanism of
the machine, a shaft B provided with a coupling. flange F, friction clutch C and
pulleys A and D which latter pulley transmits its motion by means of a belt D¹ to

longitudinal movement by means of levers M and L; a sliding bed J adapted to
receive longitudinal movement by means of a cam K¹ provided with a stud K" and
handle K, bearings QQ mounted on a plate J' and supporting a suitable worm ",
a bearing T, bench V grips VI pivotally mounted on a common rod W, springs Vui

page_text: adapted to operate the grips V₁, a drum U provided with worm wheel U¹, gearing
with a worm U which may be revolved by means of a crank U¹, a reel R
provided with a brake R¹, a guide Ru and pulley r all adapted, arranged and
operating for the purposes and substantially as described and illustrated.
