PROVISIONAL SPECIFICATION.
Improvements in Machinery for Dyeing Loose Cotton, Wool, and
other Fibres.
We, ENOCH HEPPENSTALL, of Turnbridge, Huddersfield, Yorkshire, Dyer, and
EDWIN SYKES, of Turnbridge, aforesaid, Machine Maker, do hereby declare the
nature of this invention to be as follows:-
This invention relates to a loose fibre dyeing machine referred to in prior Letters
Patent granted to Leonard Weldon bearing date the 26th day of November
A.D. 1889 No. 18,973 and our improvements in such machines consist in causing the
dye liquor in the dye vessel to circulate, that is to say, we employ a pump which
draws the dye liquor from one portion of the vessel and makes it enter in another
portion of the said vessel. By this means the liquor is in a constant state of
circulation, consequently it will impinge against the fibre in all parts of it. The
action of the pump may at times be reversed. The pipes which feed the liquor
may be perforated so as to distribute the liquor in different parts of the vessel.

We ENOCH HEPPENSTALL of Turnbridge Huddersfield Yorkshire Dyer and
EDWIN SYKES of Turnbridge aforesaid Machine Maker 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 relates to a loose fibre dyeing machine referred to in prior Letters
Patent granted to Leonard Weldon bearing date the 26th day of November 1889
No. 18973 and our improvements in such machines consist in causing the dye
liquor in the dye vessel to circulate, that is to say, we employ a pump which draws
the dye liquor from one portion of the vessel and makes it enter in another portion
of the said vessel.
Such being the nature and object of our said invention we will now proceed to
describe the same more fully and for that purpose make reference to the accom-
panying sheet of drawings, wherein
Fig. 1 is sectional elevation, Fig. 2 end elevation and Fig. 3 plan of such parts of a
dyeing vessel as are necessary to shew the application thereto of our improvements.
A is the vat or cistern containing the liquor, and in order to keep the said
liquor in a constant state of circulation, I employ a centrifugal pump B caused
to rotate by driving pulleys C. The liquor which is supplied to the vat A from
any suitable source is drawn by the pump B through pipe I, and forced into pipe D
from whence through another pipe or pipes E, arranged at the bottom of the dye

page_text: vessel into perforated pipes F connected to said pipe or pipes E, so that on the
liquor escaping through the perforations, it impinges on the fibre and assists to dye
it equally in all parts.
To reverse or change the circulation of the dye liquor the valve J may be shut
off and valve K opened whereby the liquor will be taken from the top of the vessel
at point H instead of from the bottom thereof and as in the previous case will be
forced into pipes F and distributed equally amongst the fibre. By keeping the
dye liquor in a constant state of circulation the shade of colour upon the fibre will
be equal throughout. On the pipe D is a four-way valve G which is used to shut
off communication either with the vessel A or with the pump B when it is desired
to discharge the dye liquor into the drain, that is to say if the valve is closed to
the vessel A the liquor from the pump B is forced through pipe G¹ into the drain
and if closed to the pump, the liquor runs from the vessel through pipe D into
pipe G which is also in communication with the drain. When however the liquor
is required again it is forced by the pump through a pipe D¹ into a suitable
storage tank from which it is resupplied to the dye-vessel by a separate service of
feed pipes.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
In a dyeing machine for dyeing loose cotton, and other fibres, the combination
therewith of an arrangement of pipes and pump for circulating the dyeing liquor
all arranged and operating in the manner substantially as shewn and described.
