IMPROVEMENTS IN WEAVING DOUBLE PILE FABRICS
Year: 1859

page_text: LETTERS PATENT to Philip Hill, of Manchester, in the County of Lan-
caster, Weaver, and John Moore, of Salford, in the same County, Small
Ware Manufacturer, for the Invention of "IMPROVEMENTS IN WEAVING
DOUBLE PILE FABRICS."
Sealed the 10th June 1859, and dated the 12th April 1859.
PROVISIONAL SPECIFICATION left by the said Philip Hill and John Moore
at the Office of the Commissioners of Patents, with their Petition, on
the 12th April 1859.
We, PHILIP HILL, of Manchester, in the County of Lancaster, Weaver, and
JOHN MOORE, of Salford, in the same County, Small Ware Manufacturer, do
hereby declare the nature of the Invention for "IMPROVEMENTS IN WEAVING
DOUBLE PILE FABRICS," to be as follows:-
This Invention has for its object improvements in weaving double pile
fabrics. For these purposes, in place of the arrangements of warp rollers and
of leaves of heddles heretofore used when weaving such fabrics, six warp
beams or rollers are employed and eight leaves of heddles. Two of the six
rollers or beams have the ground warps wound thereon, and the pile warps are
wound on to the other four beams or rollers. The ground warps are passed
through and actuated by four leaves of heddles, and the pile warps are passed
through and actuated by four leaves of heddles. The batten or slay is caused
to beat up twice for each weft, and the shed in the warps is changed between
the two beats. An extra leaf of heddles is used to divide the warps, in order
to keep the warps clear.

by the said Philip Hill and John Moore in the Great Seal Patent Office
on the 11th October 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, PHILIP
HILL, of Manchester, in the County of Lancaster, Weaver, and JOHN MOORE,
of Salford, in the same County, Small Ware Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of April, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Philip Hill and John Moore, Her special licence that we, the
said Philip Hill and John Moore, our executors, administrators, and
assigns, or such others as we, the said Philip Hill and John Moore, our
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 WEAVING
DOUBLE PILE FABRICS," upon the condition (amongst others) that we, the said
Philip Hill and John Moore, our executors or administrators, by an instru-
ment in writing under our or their hands and seals, or under the hand and
seal of one of us or them, should particularly 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 immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Moore, on behalf of myself and
the said Philip Hill, 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 :-
This Invention has for its object improvements in weaving double pile
fabrics. For these purposes, in place of the arrangements of warp rollers
and of leaves of heddles heretofore used when weaving such fabrics, six warp
beams or rollers are employed and eight leaves of heddles; two of the six
rollers or beams have the ground warps wound thereon, and the pile warps
are wound on to the other four beams or rollers. The ground warps are
passed through and actuated by four leaves of heddles, and the pile warps
are passed through and actuated by four leaves of heddles. The batten or
slay is caused to beat up twice for each weft, and the shed in the warps is

page_text: changed between the two beats. An extra leaf of heddles is used to divide
the warps, in order to keep the warps clear. This extra leaf of heddles
remains stationary during the process of weaving, no eyes being used therein,
but only single heald threads, between which the warp threads move up and
down, thus clearing themselves. The clearer leaf of heddles is set at the
back of the other leaves of heddles.
Having thus stated the nature of our Invention, we will proceed more fully
to describe the manner of performing the same.
The Diagram hereunto annexed shows the tie-up, which we prefer both in
respect to the ground and the pile yarns; the same, however, may be varied
without departing from our Invention, so long as the arrangement of leaves
of heddles and rollers or beams herein described be retained. There are four
leaves of heddles for the pile and four leaves of heddles for the ground warp,
and an extra or clearer leaf of heddles in order to keep the warps clear.
In witness whereof, I, the said John Moore have hereunto set my
hand and seal, this Thirtieth day of September, in the year of our
Lord One thousand eight hundred and fifty-nine.
JOHN MOORE.
