Year: 1833

page_text: TO ALL TO, WHOM THESE PRESENTS SHALL ME, I, ROBERT
WILLIAM SIEVIER, of Southampton, now in the Parish of Saint George,
Bloomsbury, in the County of Middlesex, Gentleman, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourthi,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Seventeenth day of January, One thousand eight hundred
and thirty-three, and in the third year of His reign, did, for Himself, His
heirs and successors, give and grant unto me, the said Robert Williamı Sievier,
His especial licence, full power, sole privilege and authority, that I, the said
Robert William Sievier, my executors, administrators, and assigns, or such
others as I, the said Robert William Sievier, my executors, administrators, 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 mentioned, should and lawfully
might inake, use, exercise, and vend, within England, Wales, and the Town
of Berwick-upon-Tweed, my Invention of "AN IMPROVEMENT OR IMPROVEMENTS
IN THE MAKING OR MANUFACTURING OF ELASTIC GOODS OR FABRICS, APPLICABLE TO
VARIOUS USEFUL PURPOSES;" in which said Letters Patent is contained a proviso
obliging me, the said Robert William Sievier, by an instrument in writing
under my hand and seal, particularly to describe and ascertain the nature of
my said Invention,, and in what manner the same is to be performed, and to
cause the same to be inrolled in His 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.

page_text: NOW KNOW YE, that in compliance with the said proviso, -1, the said
Robert William Sievier, do hereby declare that. the nature of my said Inven-
tion, and the manner in which the same is to be performed, are particularly
described and ascertained in and by the following description thereof, that is
to say:
My Invention of "An Improvement or Improvements in the Making or
Manufacturing of Elastic Goods or Fabrics applicable to various useful
Purposes," are designed for the production of an elastic webb, cloth, or other
manufactured fabric for bandages, and for such articles of dress as the same
may be applicable to.
The first object which I propose, is to manufacture an article by the
ordinary knitting frame or similar kind of machinery, in which cords
or strands of india rubber shall be introduced between the loops or stitches.
of the fabric for the purpose of forming elastic cords or bands round the
margins or other parts of stockings, socks, gloves, night caps, drawers, and
various other articles of clothing.
The second object is to manufacture in the ordinary loom an elastic
woollen cloth by the introduction of cords or strands of india rubber among
the longitudinal threads or yards, which constitute the chain or warp; and
also among the transverse threads or yarns which constitute the weft or
shoot, and which cloth shall be capable of being afterwards felted and dressed
with a nap:
The third object is to produce a cloth from cotton, flax, or other suitable
material not capable of felting, in which shall be interwoven elastic cords
or strands of indian rubber, coated or wound round with a filamentous
material.
The first of these improvements I effect by preparing knitting frames or
other similar machines in the usual way, for the production of the knitted
materials called stocking fabric, and when the same are set to work, and the
fabric has been manufactured by the ordinary knitting process up to the part
at which I desire to introduce the elastic cord or strand, I then, by the adjusting
screws of the machine, provide for the elongation or contraction of the lengths
of the loops or stitches of the row next to be produced across the machine, in
order to form a channel to receive the said elastic cord or strand; and having
prepared fine strips of indian rubber, which may, if desired, be coated or covered
with a filamentous material, as described in the Specification of my Patent,
dated the First day of December, One thousand eight hundred and thirty-one,
and inrolled in the Office of the Rolls Chapel, in the High Court of Chancery,
in June, One thousand eight hundred and thirty-two. I conduct such

page_text: thread cord,. strand, or strip of indian rubber by means of a long needle, hook,
pincers, or other suitable apparatus answering the purpose of a shuttle,
across the machine, between the row of stitches or loops which were last
made and those which are then about to be formed, and having drawn the
said indian rubber thread, cord, or strand straight and smooth, I complete the
last-mentioned row of loops or stitches by the ordinary movements of the
machine, which encloses the indian rubber thread, cord, or strand, and keeps
it securely in its place interwoven with the threads of the fabric. A second
thread of indian rubber is in like manner introduced between the next or other
subsequent row of stitches, and is in the same way confined; and any further
number of these threads, cords, or strands may, by the same means, be
inserted and interwoven into the fabric at such parts as may be required for
the purpose of producing (when the selvages are connected or whipped
together) elastic bandages, garters, or bracings round the stocking, sock,
glove, nightcap, or other article of wearing apparel.
In effecting the second improvement, the production of an elastic woollen
cloth, I introduce into the loom among the longitudinal or warp threads
or. yarns of the intended fabric longitudinal threads, cords, or strands of
indian rubber, or I constitute the warp entirely of such strands, either
covered with a filamentous material or not, as before. described, and through
or between the threads, cords, or strands of warp I pass the transverse weft
or shoot threads or yarns in the ordinary way of weaving, for the purpose,
of effecting that intervention, which produces the cloth, these transverse or
weft threads being composed in part of the indian rubber strands, or of the
ordinary threads or yarns of the fabric, according as I may wish to produce
a cloth which shall be elastic lengthwise only or in both directions. If the
elastic cloth so produced should be intended for outer garments, with a nap
upon its surface, I should employ, in connection with the indian rubber strands,
yarns spun from short wool, which, after having been woven, I should finish.
as the woollen cloths are usually finished, that is, felt the wool in the fulling
stock, raise the pile by gig machinery, or by hand, cards, or teazles, and
afterwards shear the nap down to a fine smooth surface. In manufacturing
an elastic cloth from cotton, flax, or other material, which is not intended to
be milled or fulled, I introduce into the fabric, threads or strands of indian
rubber, which have been previously covered by winding filaments tightly
round them through the agency of an ordinary covering machine or otherwise,
these strands of indian rubber being applied as warp or weft, or as both,
according to the direction of the elasticity required. By thus combining the
strands of indian rubber with yarns of cotton, flax, or other non-elastic material,

page_text: I am enabled to produce a cloth which shall afford any required degree.of
elastic pressure, according to the proportions of the elastic and non-elastic
material. It remains only to add, that the strands of indian rubber are in the
first instance stretched to their utmost tension and rendered non-elastic, as
described in my former Patent; and being in that state introduced in the
fabric, they acquire their elasticity by the application of heat after the fabric
is made.
Lastly, as my Invention consists solely in the employment of strands of
indian rubber in connection with yarns in the way described for manu-
facturing elastic goods or fabrics, I have-not deemed it necessary to describe
any particular kind of machinery for carrying the same into effect, as such
machinery is well known and forms no part of my Invention.
In witness whereof, I, the said Robert William Sievier, have hereunto
set my hand and seal, this Seventeenth day of July, in the year
of our Lord One thousand eight hundred and thirty-three.
ROBERT WILLIAM (L.S.) SIEVIER.
AND BE IT REMEMBERED, that on the Seventeenth day of July, in the
fourth
year of the reign of His late Majesty King William the Fourth, the
said Robert William Sievier came before our said Lord the King in His
Chancery, and acknowledged the Instrument aforesaid, and all and every
thing therein contained and specified, in form above written. And also the
Instrument aforesaid was stamped according to the tenor of the Statute made
in tlie fifty-fifth year of the reign of His late Majesty King George the
Third.
