of Farnworth, in the County of Lancaster, Spinner and Manufacturer, for the
Invention of "IMPROVEMENTS IN THE MANUFACTURE OF CERTAIN WOVEN
FABRICA
"
Sealed the 5th September 1879, and dated the 27th March 1879.
PROVISIONAL SPECIFICATION left by the said Alfred Topp at the Office of
the Commissioners of Patents on the 27th March 1879.
ALFRED TOPP, of the Firm of Messieurs Topp and Hindley, of Farnworth, in
the County of Lancaster, Spinuer and Manufacturer. "IMPROVEMENTS IN THE
MANUFACTURE OF CERTAIN WOVEN FABRICS."
My Invention relates to the manufacture of the woven fabrics known as mole-
skins, and it consists in an improved mode of floating the weft over the warp to
produce the desired result.
In performing my Invention I use a loom of the ordinary construction with oight
shafts, but instead of weaving the cloth with the whole of the weft on the face, as
is now customary, I divide the weft equally between the back and the face; this
is done by floating the weft under two and over six warp threads, and over two
and under six warp threads alternatoly.
By this means the cloth will finish equally well both on the hack and face sides,
instead of finishing on one side only, like moleskins made in the ordinary manner.
Our improved cloth can be printed on both sides, so that when one side is worn
it may be turned and the other side used.

IMPROVEMENTS IN THE
My Invention relates to the manufacture of the woven fabrics known as mole-
skins, and it consists in an improved mode of floating the weft over the warp to
produce the desired result.
In performing my Invention I use a loom of the ordinary construction with 8
shafts, 16 picks to the round, but instead of weaving the cloth with the greater
part of the weft on the face, as is now customary, I divide the weft equally between
the back and the face; this is done by floating the weft under two and over six
warp threads, and over two and under six warp threads alternately. By this
means the cloth will finish equally well both on the back and face sides, instead of
finishing on one side only, like moleskins made in the ordinary manner.
The accompanying diagram represents the pattern or tie up for producing my
improved fabric; the blank spaces and dots shew the order of succession in which
the threads of the warp rise and fall to form the sheds.
My improved cloth can be printed on both sides, so that when one side is worn
it may be turned and the other side used.
Having thus stated the nature of my Invention, and described the manner of
performing the same, I declare that I claim,-Floating the weft under and over the
warp for the purpose described.
In witness whereof, I, the said Alfred Topp, have hereunto set my hand
and seal, this Twenty-fourth day of September, One thousand eight
hundred and seventy nine.
ALFRED TOPP. (L.S.)
