COMPLETE SPECIFICATION,
Improvements in Apparatus for Dyeing, Bleaching, and otherwise
Treating Cops of Yarn.
1, WILLIAM BEAUMONT, of 85 Booth Street, Stockport, in the County of Chester,
Engineer, 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:-
My invention relates to improvements in apparatus for dyeing, bleaching and
otherwise treating cops of yarn and the object of my improvements is to construct
a cheap, simple and efficient apparatus for this purpose.
In the accompanying Sheet of Drawings
Fig. 1 is an elevation partly in section of an apparatus constructed according
to my Invention and Figs. 2 and 3 are detail views of parts of the same.
In the Drawings, represents the vessel in which the operation of dyeing
bleaching or otherwise treating cops of yarn is carried out, 3 the cover held down
by bolts hinged to the upper part of the vessel, ti a cop plate shown in plan in
Fig. 3, connected to a handle bar 7, and the cop plate, when in position in the
vessel, rests upon an annular ledge S. The bottom of the vessel is connected to
a pipe 9, in communication with a circulating pump 10, which is connected by a
pipe 11 to the upper part of the vessel, in which is a plate 12 for deflecting the
liquor as it enters; to another portion of the vessel above the cop plate 6 is con-
nected a steam pipe 13 the mouth of which is preferably protected by a perforated
or other plate 14 for breaking up the jet of steam. A pressure gauge 15 is con-
nected to the upper part of the vessel and a vacuum gauge 16 is connected to the
vessel just below the cop plate. The cops are placed upon perforated cop tubes 17
which are fitted in the cop plate 6, and when the latter is filled with cops and is
placed on the ledge 8 the vessel is filled nearly up to the top with boiling dye or
other liquor and the cover 3 is placed on the vessel and secured by the pivoted
bolts 4. The pump 10 is then set in motion by a driving band, not shown, on one
of a pair of pulleys 18; the effect of this is to withdraw the dye or other liquor
and so form a partial vacuum below the cops thereby drawing the liquor from the
upper part of the vessel through the cops and tubes to the under side of the cop
plate 6 and so long as the pump is kept in motion the liquor is circulated through
the vessel and cops, the temperature of the liquor being maintained by admitting
steam through the pipe 13.
When the cups have been sufficiently dyed, bleached or otherwise treated the
cover is removed and raised in any convenient manner, after which the cop plate
can be withdrawn and a fresh one filled with cops placed into the vessel ready for
another dyeing or similar operation.
A waste cock is fitted on the pipe 9 in order to draw off the liquor when
required.
Having now particularly described and ascertained the nature of my said In-
vention and in what manner the same is to be performed I declare that what I
claim is:-
1. In combination, a dyeing bleaching or similar vessel, a perforated cop plate

page_text: dividing such vessel into two chambers and inlet and outlet passages in com-
munication with a circulating pump substantially as and for the purposes herein
described and as shown.
2. The general construction combination and arrangement of parts embodying
my improvements in apparatus for dyeing, bleaching and otherwise treating cops
of yarn substantially as herein set forth.
