Improvements in Apparatus Employed in Finishing Textile
Fabrics.
We, JAMES SHARP, MILTON SHERIDAN SHARP, JAMES SHARP the younger, and
JOHN CASSON, Dyers, all of the firm of Messieurs James Sharp and Sons, Tower Dye
Works, Low Moor, near Bradford, in the County of York do hereby declare the
nature of this Invention to be as follows
The object of our invention is in finishing textiles to expedite and produce a greater
and more permanent lustre than has hitherto been produced by any known method;
and consists in the application and use of additional mechanical appliances, not
hitherto employed in finishing textile fabrics, such additional mechanical appliances
may be used in conjunction with or separately from the mechanical appliances now in
general use for finishing textile fabrics especially for linings or Italian cloths, or other
heavy textile fabrics.
In finishing such goods after the well-known processes such as crabbing and singeing,
which are employed to obtain a smooth surface, and to develope the natural lustre of
the fibres, have been applied, the goods are dyed, washed and dried, in the ordinary
way, after which such goods are, or may be, conditioned for the final finishing pro-
cesses by the application under certain conditions of any one or more of the following
ingredients, namely, soap water, glycerine, oil, or oleaginous substances, wax,
spermaceti, gums, or other glutinous substances, or such other substances as are
known in the trade.
The goods so conditioned are then pressed with the ordinary steam presses, the
plates of such presses being constructed with hollow passages for the purpose of
being heated and cooled by water or steam, or other heating and cooling media, whilst
the goods are being pressed and finished under hydraulic or other pressure.
The defects hitherto arising in goods so finished are two-fold, first, the lustre so
produced is not sufficiently silky in appearance, and secondly, such lustre is not
permanent or fixed, so that when a wet cloth is put upon the goods so finished, and
a hot iron or Tailors goose is put upon the wet cloth much of the finish or lustre is
removed, and a dull imperfect appearance is manifest.

page_text: We especially claim as novel, the application and use of special additional
mechanical appliances for drying the goods after the conditioning process, in which
the goods have been impregnated or saturated with such agent or agents as are best
calculated to promote increased lustre and permanency of finish upon the goods,
whilst placed under and over a specially constructed metal plate in an ordinary
finishing press.
When applying our invention to the plates of ordinary presses we either form
corrugations or channels of any suitable form and by any suitable means in or upon
the ordinary pressing surfaces (above and below) of the pressing plates; or, we affix
upon each pressing surface a specially constructed metallic plate of iron, steel, copper,
brass, or other suitable metal, with similar corrugations or channels formed thereon,
and we then place upon each such corrugated or channelled surface a perforated
plate, preferably of copper or brass, but the same may be made of any other suitable
metal.
The corrugated or channelled surfaces above described covered with the perforated
metallic plates above mentioned and which may be constructed either in separate
parts or plates or applied to or constructed to form parts of the plates of an ordinary
finishing press act as channels or conduits through which the surplus conditioning
agents either in the form of a liquid or of vapours travel or escape during the
ordinary drying process which may be performed with or without pressure and
thereby and in consequence thereof a greater lustre is produced upon the goods being
finished and a permanent or fast finish is obtained.

Improvements in Apparatus Employed in Finishing Textile
Fabrics.
We JAMES SHARP, MILTON SHERIDAN SHARP, JAMES SHARP the younger, and
JOHN CASSON Dyers, all of the firm of Messieurs James Sharp and Sons, Tower Dye
Works, Low Moor, near Bradford in the county of York, 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 :-
The object of our invention is in finishing textiles, to expedite and produce a greater
and more permanent lustre than has hitherto been produced by any known method; and
consists in the application and use of additional mechanical appliances, not hitherto
emploved in finishing textile fabrics, such additional mechanical appliances may be
used in conjunction with, or separately from, the mechanical appliances now in
general use for finishing textile fabrics, especially for linings, or Italian cloths, or
other heavy textile fabrics.
In finishing such goods after the well known processes such as crabbing and singeing,
which are employed to obtain a smooth surface, and to develope the natural lustre of
the fibres have been applied, the goods are dyed, washed, and dried in the ordinary
way, after which such goods are, or may be, conditioned for the final finishing pro-
cesses, by the application under certain conditions of any one, or more of the following
ingredients, namely, soap, water, glycerine, oil, or oleaginous substances, wax,
spermaceti, gums, or other glutinous substances, or such other substances as are known
in the Trade.
The goods so conditioned are then pressed with the ordinary steam presses, the
plates of such presses being constructed with hollow passages for the purpose of being
heated and cooled by water, steam, or other heating and cooling media, whilst the
goods are being pressed and finished under hydraulic or other pressure.
The defects hitherto arising in goods so finished are two fold, first, the lustre so
produced is not sufficiently silky in appearance, and secondly, such lustre is not
permanent or fixed, so that when a wet cloth is put upon the goods so finished, and
a hot iron or Tailor's goose is put upon the wet cloth, much of the finish or lustre is
removed, and a dull imperfect appearance is manifest.
We especially claim as novel, the application and use of special additional
mechanical appliances for drying the goods after the conditioning process, in which
the goods have been impregnated or saturated with such agent or agents, as are
best calculated to promote increased lustre and perinanency of finish upon the goods,
whilst placed under and over a specially constructed metal plate in an ordinary
finishing press.
When applying our invention to the plates of ordinary presses, we either form
corrugations or channels of any suitable form, and by any suitable means in or upon
the ordinary pressing surfaces (above and below) of the pressing plates; or we affix
upon each pressing surface a specially constructed metallic plate of iron, steel, copper,

page_text: brass, or other suitable metal, with similar corrugations or channels formed thereon,
and we then place upon each such corrugated or channelled surface a perforated
plate or wire gauze, or other suitable equivalent, preferably of copper or brass, but
the same may be made of any other suitablo metal or substance.
The corrugated or channelled surfaces above described covered with the perforated
metallic, or other plates above mentioned, and which may be constructed either in
separate parts or plates, or applied to, or constructed to form parts of the plates of an
ordinary finishing press, act as channels or conduits, through which the surplus con-
ditioning agents, either in the form of a liquid, or of vapours, travel or escape during
the drying process which may be performed, with or without pressure and thereby.
and in consequence thereof, a greater lustre is produced upon the goods being
finished, and a permanent or fast finish is obtained.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a front elevation showing ordinary press plates, and our improved loose
Aluted or corrugated plates, and perforated plates in position.
Fig. 2 shows a modified elevation with channels or corrugations upon the pressing
surfaces of the press plates, and a perforated plate upon each such surface, above and
below.
Fig. 3 is a plan of corrugated or channelled plates.
Fig. 4 is a plan of perforated plates.
Fig.
5 shows corrugations or channels upon the plate in a diagonal form.
A is the press plate, B is the corrugated or channelled plate, C is the perforated
plate, or wire gauze, or other suitable equivalent.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed we declare that what we
claim is: -
The use and employment of corrugated or channelled surfaces covered with
perforated plates, metallic gauzes, (or their equivalent), which may be constructed,
wither in separate parts, or applied to, or form part of, the ordinary press plates, so
as to act as channels or conduits through which the surplus conditioning agents
travel or escape, substantially as and for the purposes as hereinbefore shown and
described.
