PROVISIONAL SPECIFICATION.
Improvements in or in connection with Weaving Fast Weft Pile
Cotton Dusters or Polishing Cloths.
I, DUGALD SCOTT of 12 York Street, Manchester, in the County of
Lancashire, Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in or in connection with weaving fast
weft pile dusters or polishing cloths of cotton and has for its object to increase the
rate of production of such fabric that is to say to greatly increase the output of
the looms without increasing the rate of running, material alteration in, or increased
cost in operating, said looms; whereby I am enabled to greatly cheapen the cost of
production of said dusters or polishing eloths.
My present invention is as follows:-
I first wind two threads (of any suitable quality and count for producing a weft
pile fabric of the character known as cotton velvet or velveteen with a fast pile)
on one cop or pirn, for use in an ordinary or any suitable shuttle.
To ensure these two threads running off the pirn or cop evenly and exactly
together and obviate the possibility or likelihood of same becoming entangled or
unequally woven into the fabric I twist these two threads together.
This twist (which may be of any desired. amount for instance one twist in 3 or
4 inches) may be imparted in any suitable manner either before same is wound on
the cop or pirn or in the operation of so winding on. Great care should be taken
to have the two threads carefully and evenly laid together and for this purpose I
bave found it advantageous to first draw off the thread from each of two cops (just
as same come from the mule or spinning frame) on to a reel or bobbin without
twisting them together and then run said two threads on to the cop or pirn ready
for the shuttle now imparting the desired twist in any suitable manuer for instance
by a flyer as same are wound on to the said cop.
The cop or pirn (with the two threads thus carefully wound thereon) is now
placed in the shuttle and the shuttle in the loom in the usual well known or other
suitable manner.
I now proceed to weave a fabric on a fast pile tie-up so that at each traverse of
the shuttle through the warp I thereby produce the effect or equivalent of two
picks and thus the rate of production is doubled or nearly so i.e. two yards of fabric
of about the same number of weft threads to the inch will according to my present
invention be made in the same number of traverses of the shuttle as would produce
only one yard with a single thread of same size.
The pile is cut in the manner known as fustian cutting or any other suitable
manner and then when the cut pile ends are brushed and finished (in the usual
manner) the cut ends of each pair of threads will readily untwist and each individual
pile end will be free and clear of the other as in the ordinary single weft eut pile
fabric as made heretofore.
Instead of using two threads on one cop or pirn I may use two cops or piros
in the shuttle although in practice the former will be found very advantageous
as it enables existing shuttles and shuttle boxes etc. to be used without alteration.
In order to thus weave a fast pile fabric (with two weft threads at one traverse
of the shuttle) I effect the tie-up in the following manner.

page_text: I put in a lash pile (on say 8 shafts, to float 5 ends or other suitable number of
shafts and ends in the proper proportions as is well understood-always binding on
3 ends or more of the warp so as to ensure a fast pile) 3 face picks i.e. three double
picks, to one binder pick (i.e. one double thread binder) and when using No. 60
weft (2 as 1) I find about 240 picks i.e. 240 double picks per inch to produce a
good material although other counts of weft and other number of picks to the
inch and also other proportions of face picks to binder picks may be used if
desired.
If desired a pile surface may be woven on both sides of the fabric according to
my present invention. The tie up in this case being so arranged as to produce on
both sides of the fabric the effect before described as having been produced on one
face only for instance three (double) pile picks on the front and three (double)
pile picks on the back (these picks being alternately front and back) and then a
binder pick.
The fabric thus produced is now finished singed etc. and cut up in the manner
specified in my Patent No. 21,399 of 1891 or in any other suitable manner and these
dusters or polishing cloths are now ready for the market being thus produced in a
very expeditious and economical manuer.

Improvements in or in connection with Weaving Fast Weft Pile
Cotton Dusters or Polishing Cloths.
I, DUGALD SCOTT of 12 York Street, Manchester, in the County. of
Lancashire, Manufacturer, 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 improvements in or in connection with weaving fast
weft pile dusters or polishing cloths of cotton and has for its object to increase the
rate of production of such fabric that is to say to greatly increase the output of
the looms without increasing the rate of running, material alteration in, or increased
cost in operating, said looms; whereby I am enabled to greatly cheapen the cost of
production of said dusters or polishing cloths.
My present invention is as follows:-
I first wind two threads (of any suitable quality and count for producing a weft
pile fabric of the character known as cotton velvet or velveteen with a fast pile)
on one cop or pirn, for use in an ordinary or any suitable shuttle.
To ensure these two threads running off the pirn or cop evenly and exactly
together and obviate the possibility or likelihood of same becoming entangled or
unequally woven into the fabric I twist these two threads together.
This twist (which may be of any desired amount-for instance one twist in 3 or
4 inches) may be imparted to the threads in any suitable manner either before they

should be taken to have the two threads carefully and evenly laid together and for
this purpose I have found it advantageous to first draw off the thread from each of
two cops (just as same come from the mule or spinning frame) on to a reel or bobbin
without twisting them together and then run said two threads on to the cop or pirn
ready for the shuttle now imparting the desired twist in any suitable manner for
instance by a flyer as same are wound on to the said cop.

page_text: The cop or pirn (with the two threads thus carefully wound thereon) is now
placed in the shuttle and the shuttle in the loom in the usual well known or other
suitable manner.
I now proceed to weave a fabric on a fast pile tie-up so that at each traverse of
the shuttle through the warp I produce the effect or equivalent of two picks and
thus the rate of production is doubled or nearly so i.e. two yards of fabric of about
the same number of weft threads to the inch will according to my present invention
be made in the same number of traverses of the shuttle as would produce only one
yard or thereabouts with a single thread of same size.
The pile is cut in the manner known as fustian cutting or any other suitable
manner and then when the cut pile ends are brushed and finished (in the usual
manner) the cut ends of each pair of threads will readily untwist and each individual
pile end will be free and clear of the other as in the ordinary single weft cut pile
fabric as made heretofore.
In order to thus weave a fast pile fabric (with two weft threads at one traverse of
the shuttle) I effect the tie-up in the following manner.
I put in a lash pile (on say 8 shafts, to float 5 ends or other suitable number of
shafts and ends in the proper proportions as is well understood-always binding on
3 ends or more of the warp so as to ensure a fast pile) 3 face picks i.e. three double
picks, to one binder pick (i.e. one double thread binder) and when using No. 60
weft (2 as 1) I find about 240 picks i.e. 240 double picks per inch to produce a
good material although other counts of weft and other number of picks to the
inch and also other proportions of face picks to binder picks may be used if
desired.
If desired a pile surface may be woven on both sides of the fabric according to
my present invention. The tie up in this case being so arranged as to produce on
both sides of the fabric the effect before described as having been produced on one
face only for instance three (double) pile picks on the front and three (double)
pile picks on the back (these picks being alternately front and back) and then a
binder pick.
The fabric thus produced is now finished singed etc. and cut up in the manner
specified in my Patent No. 21399 of 1891 or in any other suitable manner and these
dusters or polishing cloths are now ready for the market being thus produced in a
very expeditious and economical manner.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I would remark that I
am aware that it has been proposed to use two separate threads on two separate
cops or pirns in one shuttle so that two picks are thereby produced at each traverse
of the shuttle but so far as I am aware two threads on one cop or pirn in a shuttle
have not heretofore been used in the manner herein described therefore I declare
that what I claim and claim only is :-
:-
1. In weaving fast weft pile cotton dusters or polishing cloths-the employment
of two threads loosely twisted together on one cop or pirn to produce the effect or
equivalent of two picks at each traverse of the shuttle.
2. In weaving fast weft pile cotton dusters or polishing cloths-the employment
of two threads on one cop or pirn in the shuttle said threads being twisted together
substantially in the manner and for the purposes herein before described.
3. Weaving fast weft pile cotton dusters or polishing cloths substantially in the
manner and for the purposes herein before described.
