:
I, WILLIAM REID, Manager to Messieurs Donald, Matheson, and
Company, of Govan Croft Dye Works, in the County of Lanark, North
Britain, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN APPARATUS FOR SATURATING YARNS AND OTHER TEXTILE MATERIALS WITH
BLEACHING, PREPARING, MORDANTING, DYEING, CLEARING, OR OTHER LIQUIDS,”
be as follows:—
This Invention has for its object the constructing or arranging of
apparatus for saturating yarns and other, textile materials with liquids
of various kinds in an improved manner, and so that the materials may
be subjected to less handling and less risk of injury than in existing
apparatus for the same purpose.
In carrying out the Invention the liquid with which the textile
materials are to be saturated may be contained in a vat, tank, boiler, or
vessel of any convenient form. The materials are conveyed into,
through, and out, of the vessel by means of a pair of endless conveying

webs, which are led round a series of guide rollers. These guide rollers
are placed so that the two webs may for portions of their courses be
near and parallel to each other, and proper motions are given to the
webs by driving their rollers, or some of them, so that the parts of the
two webs which are near together may move in the same direction. The
yarns or other textile materials are introduced between the contiguous
parts of the two webs, and are conveyed along the desired course by
their action. The web which is undermost at the entering part is there
carried further out than the upper one by being passed round an
additional guide roller, and thus forms an uncovered surface on which
the yarns or textile materials may be laid, the motion of the web then
carrying them in between itself and the upper web. The lower web
may be similarly extended at the exit end to facilitate the delivery of the
materials. Some of the rollers may be arranged to compress the
materials, and in particular there may be one or more pairs of rollers at
the exit end strongly compressed together, in order to expel the liquid
as much as possible from the materials on their leaving the vessel.
The conveying webs may be made of any suitable woven fabric or
permeable material, and wire gauze or other metallic webbing will
probably be found to be conveniently and advantageously applicable in
some cases.
Two or more vessels may be placed in connection and with the
delivery part of the conveying webs of one arranged to deliver the yarns
or other textile materials upon the entering part of the next. In this
way the yarns or other textile materials may be passed continuously
through a number of vessels, and be saturated with different liquids
in each, without the frequent handling and consequent labour required
with existing apparatus for the same purposes.
The improved apparatus will be very well adapted for treating wool or
other fibrous materials in the unspun or partly spun state. Or one pair
of conveying webs may be led through two or more separate vessels.
