PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Twilled Cloths.
I, JOHN VINCENT REBBLA of Providence Mills, Batley in the County of York,
Woollen Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention consists of an improved manufacture of small twills or diagonals,
effecting economy in cost of weaving and in quantity of warp or ends required, the
weave will be fully understood from the following comparison between the old or
ordinary way of producing twills and the improved or new way.
In the old way there is employed one pick of face weft to one pick of backing
weft whereas I employ two picks of face weft to one pick of backing weft producing
a finer face to the piece.
In say a piece of 60 picks per inch, pick to face and pick to backing gives 30 picks
to each, but if the piece be woven according to my improvements of two to one then
45 picks only would be required, 30 to the face and 15 to the back to produce like
result thereby effecting a considerable saving in labour and loom work as whereas 12
shafts would be requisite to produce a 4 twill on the old plan, 10 shafts would suffice
on the new, effecting a saving of 2 shafts and whilst 12 shafts would require 3800
ends for a whole warp in worsted 10 shafts would require 3160 ends effecting a
saving of 640 ends and producing equally fine appearance on face of the piece.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Twilled Cloths.
I, JOHN VINCENT REBBLA of Providence Mills, Batley, in the County of York,
Woollen 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 consists of an improved manufacture of small twills, or diagonals,
effecting economy in cost of weaving, and in quantity of warp or ends required.
Such being the nature and object of my said invention, the following is a complete
description of same, and the weave will be fully understood from the comparison
between the old or ordinary way of producing twills, and the improved or new way,
and in aid of the description I have annexed a diagram of the weave, which will be
fully understood by those practically acquainted with weaving.
In the old way there is employed one pick of face weft to one pick of backing
weft, whereas I employ two picks of face weft to one pick of backing weft, producing
a finer face to the piece.
In, say a piece of 60 picks per inch, pick to face, and pick to backing, gives 30
picks to each, but if the piece be woven according to my improvements of two to
one, then 45 picks only would be required, 30 to the face and 15 to the back, to
produce like result, thereby effecting considerable saving in labour and loom work,
as whereas 12 shafts would be requisite to produce a 4 twill on the old plan, 10 shafts
would suffice on the new plan, effecting a saving of 2 shafts, and whilst 12 shafts
would require 3800 ends for a whole warp in worsted, 10 shafts would require
3160 ends, effecting a saving of 640 ends, and producing equally fine appearance on
the face of the piece.

page_text: Having now particularly described and ascertained the nature and object of
my invention and in what manner the same is to be performed I declare that what
I claim is:-
The improvements in the manufacture of twilled cloths effected as and by the
