IMPROVEMENTS IN THE MANUFACTURE OF PRINTED TAPESTRY' CARPETS
Year: 1867

page_text: LETTERS PATENT to William Wood, of Monkhill, near Pontefract, in the
County of York, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE
OF PRINTED TAPESTRY' CARPETS."
Sealed the 22nd November 1867, and dated the 30th May 1867.
PROVISIONAL SPECIFICATION left by the said William Wood at the
Office of the Commissioners of Patents, with his Petition, on the 30th.
May 1867.
1, WILLIAM WOOD, of Monkhill, near Pontefract, in the County of York,.
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF PRINTED TAPESTRY' CARPETS," to be as follows:-
In the manufacture of printed "tapestry" carpets it is customary to use-
straight threads of warp in the back, or body of the fabric, which are called-
"dead," for the purpose of filling up the interstices between the lines of the
real or binding warp, and for supporting the pile warp; this dead warp is
usually made of linen threads dressed smooth with size, and having 3 or 4.
threads in each space between the dents of the reed; the effect of using this
smooth sized dead warp of threads being to make the carpet comparatively
thin, hard, inelastic, and cold.
Now the object of my Invention is to make the carpet thicker, softer, more
elastic, and warm, and consists in making the dead warp wholly or partly of
certain other materials in suitable forms.
Firstly, I make the dead warp of yarns composed wholly or partly of silk.
obtained from cuttings and rags of fabrics wholly or partly of silk, which I
tear up and form into yarns of suitable size. -

page_text: Secondly, I form the dead warp of yarns made wholly or partly of wool,
hair, or such like animal fibres, either new, or obtained from cuttings and
rags, or old carpeting.
"as
In
Thirdly, I form the dead warp of jute or other vegetable fibres in the state
of "rovings" as thick as the reed will allow to pass freely through it.
any case of improved dead warp I prefer to spin or twist and size the yarns or
rovings only in a sufficient degree to enable them to be woven properly, that
is, I preserve as much softness and elasticity as possible in the dead warp,
which I also prefer to dye some suitable color.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Wood in the Great Seal Patent Office on the
29th November 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WOOD, of Monkhill, near Pontefract, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of May, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said William Wood, Her special licence that I, the said William Wood, my
executors, administrators, and assigns, or such, others as I, the said William
Wood, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN; THE MANUFACTURE
OF PRINTED. TAPESTRY' CARPETS," upon the condition (amongst others) that
I, the said William Wood, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause, the same to be filed
in the Great, Seal Patent, Office within, six, calendar months next and imme-
diately after the date of the said Letters, Patent.
NOW KNOW YE, that I, the said; William Wood, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and, by the following
statement thereof, that is to say :-

page_text: In the manufacture of printed "tapestry" carpets it is customary to use
straight threads of warp in the back or body of the fabric, which are called
dead," for the purpose of filling up the interstices between the lines of the
real or binding warp, and for supporting the pile warp. This dead warp is
usually made of linen threads dressed smooth with size, and having generally
three threads in each space between the dents of the reed, the effect of using
this smooth sized dead warp of threads being to make the carpet com-
paratively thin, hard, inelastic, and cold.
Now the object of my Invention is to make the carpet thicker, softer, more
elastic and warm, and consists in making the dead warp wholly or partly of
certain other materials in suitable forins and combinations.
partly of silk
partly of silk,
suitable fibres
Firstly, I make the dead warp of yarns composed wholly or
obtained from cuttings and rags of woven fabrics wholly or
which I tear up, and either alone or combined with any other
form by the usual or other convenient processes into yarns of suitable size
and strength.
Secondly, I form the dead warp of yarns made wholly or partly of wool,
hair, or such like animal fibres, either new or obtained from cuttings and rags
of woollen, union, or linsey fabrics and spun waste, and new or old carpeting,
these also either alone or mixed with other fibres I form by the usual or other
convenient processes into yarns of suitable size and strength. In the formation
and application of these improved yarns for dead warps I prefer to twist
and size the yarns to such extent only as will enable them to be woven
properly, that is, I preserve as much softness and elasticity as possible in the
dead warp, and to enable this to be carried out with a minimum of twist or
size, I sometimes "double" or intertwist the yarn made wholly or partly of
silk, wool, or animal fibre with a linen or other strong thread, so as by binding
them to assist the weaving of soft or short fibred yarns, and by preference
coating such thread with cementing matter.
In witness whereof, I, the said William Wood, have hereunto set my
hand and seal, this 28th day of November, in the year of our Lord
One thousand eight hundred and sixty-seven.
WILLIAM WOOD. (L.s.)
