CLARKE, of the Borough of Leicester, Dyer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Eleventh day of April, in the sixth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Uriah Clarke, Her especial licence, full power, sole privilege and authority,
that I, the said Uriah Clarke, my exors, admors, and assigns, or such others
as I, the said Uriah Clarke, my exors, admors, or assigns, should at any
time agree with, and no others, from time to time and at all times during
the term of years therein expressed, should and lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick-upon-
Tweed, my Invention of "IMPROVEMENTS IN THE MANUFACTURE OF NARROW
ELASTIC AND NON-ELASTIC FABRICS OF FIBROUS MATERIALS;" in which said
Letters Patent is contained a proviso, that I, the said Uriah Clarke, shall
cause a particular description of the nature of my said Invention, and in
what manner the same is to be performed, to be inrolled in Her said Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of the said in part recited Letters Patent, as in and by the
same, reference being thereunto had, will more fully and at large appear.
NOW KNOW, YE, that in compliance with the said proviso, I, the said
Uriah Clarke, do hereby declare that the nature of my said Invention, and

Figure 1 represents a side view of a machine constructed according to my
Invention Figure 2 is a plan thereof; and the other views shewn by the
Drawings represent various parts, separately, and combined, which are referred
to by the same letters of reference as are used in Figures 1 and 2; and as the
nature of each of the views are written on the Drawings, it will not be neces-
sary to repeat them here. The machinery is so arranged, that bobbins or other
suitable holders of spun yarn, or other suitable fibrous material, in the form
of thread or otherwise, are caused to revolve in circuits, the circuits being
arranged in such manner that they intersect each other, and the threads or
yarns of one circuit are caused to link in with the threads or yarns of other
circuits, thus producing linked fabrics, in which longitudinal strands of india-
rubber or of non-elastic material are introduced, thus producing narrow elastic
or non-elastic fabrics of a novel character, which will readily be understood on
examining Figures 3 and 4, where the fabric is shewn on a magnified scale;
Figure 3 shewing a portion of fabric having no longitudinal threadsintroduced,
it simply consisting of the threads a and b linked together; Figure 4 showing
the same fabric having longitudinal threads of india-rubber, or of non-elastic
yarn, or other fibrous material introduced, as is shewn at c, c, and when india-
rubber strands are introduced they are in what is called the non-elastic state,
and when the fabric is made and removed from the machine, elasticity is
restored to the india-rubber by means of a heated iron, as is well understood,
when restoring elasticity to india-rubber, made up into woven or braided fabrics.
d is the lower plate of the machine (shewn separately at Figure 5 in plan, edge
view, and section), having various recesses formed therein to receive the
rings e, e, which rotate in the recesses formed in the plate d, and also other
recesses to receive the cog wheels f, f, and the cog wheel g, as is shewn in
Figure 6, which Figure shews a plan of the plate d, having in the recesses
formed therein the cog rings e, c, and the cog wheels f, f, and the cog wheel g
the cog wheel g moving on the tubular axis 7, which is fixed, and the cog
wheel I, when caused to turn, as hereafter explained, gives motion to the cog
rings e, which give motion to the cog wheels f, and the cog wheels f, together
with the cog wheel g,give motion to the toothed segments, hereafter described,
which move in circuits which intersect the circuits in which the cog rings e
cog

apparatus for carrying thread or yarn in combination therewith, the thread
or yarn of the bobbins of the toothed segments will interlink.with the threads
or yarns of the cog rings, and thus produce a fabric which will be in a tubular
form or flat, according as all of the bobbins & threads are used, or less than all
the bobbins & threads are used. On the upper surface of the plate d is affixed
the plate h, composed of many pieces, as will readily be traced by examining
Figure 7,which shews a plan and under side view of the plate h, and the screw
holes for connecting the parts of the plate h to the plate d, there being circular
circuits e¹, e¹,formed through the plate h, around or in which the stems of the
bobbin apparatus move, such stems being affixed in the cog rings e, e; and
there are also openings through the plate h for the passage of the cog wheels
f,f; and the cog wheel 9, in order that those cog wheels may take into and
give motion to the toothed segments i, i, which move in the circular recesses
formed in the plate h, as is shewn, and each of these segments i carries a
bobbin, the stem of which is fixed thereto; and it will be readily understood,on
examining the nature of these parts and their mode of working together, that
as each of the cog rings e, e, carries two bobbins, and each of the segments i
carries a bobbin, and as the segments in their rotation intersect the circuits
performed by the bobbins carried by the cog rings, the threads or yarns from
the bobbins of the segments i will interlink with the threads or yarns carried
by the cog rings e, e, and thus produce a linked fabric, similar to Figure 3,
should there be no india-rubber strands or strands of non-elastic yarn intro-
duced into the fabric; and the fabric would be similar to Figure 4, if elastic or
non-elastic yarns were introduced in the making. The plan of the covering.plate
j, which covers over the working parts of the apparatus of the plate d and the
plate h, has spaces or circuits intersecting each other, through which the stems
of the bobbins move, as is shewn in Figure 2. The machine receives motion
in the following manner :-k is a pulley, which is affixed to the boss of the cog
wheel g, which moves on the fixed axis 7, the pulley receiving motion by an
endless band driven by any suitable power, and the cog wheel, as before men-
tioned, gives motion to the cog rings e, and the cog rings e give motion to the
cog wheels f, and cog wheels f, together with the cog wheel g, give motion
to the toothed segments i, as above described; and by such means the various
bobbins carried by the cog rings e and the toothed segments i will be con-
stantly movingaround in theirrespectivecircuits without departing out thereof..
the linking of the threads of the toothed segments with the threads of the cog
rings resulting from the circuits of the two sets of threads intersecting each
other, as is shewn, and as is above described. One of the cog wheels/gives

page_text: n,
motion to the cog wheel m, which gives motion to the hollow axis which
turns upon a pin affixed to the lower plate of the machine. The hollow axis
has a worm n¹ affixed thereon, which, taking into, drives the toothed wheel a
on the axis o¹, on which is affixed a graduated pulley p, which gives motion to
1.the driving band q, which is kept sufficiently tight by a dancing weight q¹, the
! band q giving motion to the bobbin r by means of the pulleys, as is shewn.
The surface motion of the bobbin being greater than the surface motion of
the largest groove of the graduated pulley 2, by which means the work as it is
produced is wound on to the bobbin, and is kept in a state of tension to ensure
: a sufficient degree of friction of the fabric upon the graduated pulley,the work
as it is produced being drawn through the guide t, and over the pulley v, as is
shewn. The bobbins for carrying the yarns which link together are similar
to those used in braiding machines, and have somewhat similar apparatus for
carrying them, but the slack is shewn to be taken up by springs in place of
weights, and the stems of the carrying apparatus of the bobbins are fixed in
the cog rings and toothed segments, as above explained. I would remark, that
the machine above described is capable of working with as many as sixteen
yarns or threads, which would, if they all be.used, produce atubular fabric; but
if two of the yarns be removed, which revolve in one circuit, then it will pro-
duce a flat fabric; and other machines may be made capable of working with
i other numbers of threads or yarns, and the parts of the machine may be other-
wise varied in their construction and mode of working, so long as the threads
respectively do not move out of their own circuits, and are caused to link
together by the circuits intersecting each other; and when it is desired to intro-
duce longitudinal threads or yarns of elastic or non-elastic materials in the
fabrics made, then the yarns are placed on suitable bobbins, which may be
affixed to a frame underneath the machine, and conducted up through the tubes
.w, w, by which means these longitudinal threads will be shut within the fabric
as the same is produced; or the bobbins or holders of the longitudinal yarns
may be otherwise conveniently applied; and when making the narrow fabrics
in the form of tubes, a longitudinal core may be introduced up the hollow axis
of the cog wheel g.

Having thus described the nature of my Invention, and the manner in which
the same is to be performed, I would wish it to be understood that I do not
claim any of the parts separately; but what I claim is,-
First, the mode of manufacturing linked narrow fabrics with or without
longitudinal threads or yarns of elastic or non-elastic materials introduced
therein, as above described.
And, secondly, I claim the making an elastic linked fabric, such as is
