We, JOHN WILKINSON, the younger, SAMUEL FILLINGHAM, and JAMES
PARDOE, all of St. Helen's Mills, Leeds, in the County of York, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR SCOURING, PREPARING FOR PRINTING, BLEACHING,
CLEANSING, DRYING, AND BEAMING WORSTED, WOOLLEN, OR OTHER YARNS," to be
as follows:-
―:
The object of our Invention is to operate upon woollen or worsted
yarns in a more effectual manner than has heretofore been done when
these yarns are operated upon in the hank in the processes of washing,
scouring, bleaching, and mordanting such yarns. To this end we
separate the yarns from each other so that the chemical solutions or
water through which they are conducted will effectually act on all
parts, and the several processes will be carried on with greater
certainty and in a more perfect manner than heretofore. To this end
the bobbins containing the yarns to be operated upon are by preference
taken direct from the doubling frame and without the yarns being

page_text: rewound or made into hanks, the bobbins are mounted in a creel from
which the yarns are drawn, and when properly separated, by being
passed through a reed or other analogous device they are conducted
into a tank or vessel containing soapsuds, or other lees; after passing
over and under carrying rollers they pass between a pair of pressing
rollers, the upper one of which is weighted in any convenient manner;
the superabundant moisture is pressed from the yarns and runs back
into the tank or vessel, after which the yarns may be conducted through
a second tank containing soapsuds or other lees, and between a second
pair of pressing rollers, and then through a vessel containing water,
which with the addition of another pressing operation will wash out
the soap or other lees from the yarns. The yarns are then passed
through a bath containing a solution of salts of tin, or other mordanting
preparation, and then through a bath of water to wash out the super-
fluous mordanting preparation.
Either before or after this mordanting process yarns may if desired
be conducted thro' a bleaching solution, such as chloride of lime or
other suitable preparation, and ultimately through one or more vessels
containing water for the purpose of washing out or removing the
superfluous bleaching solution. Pressing rollers are adapted to all the
several tanks for the purpose of expressing the moisture from the
yarns, which are finally dried by being passed round one, two, or more
heated cylinders. The yarns having thus been washed, mordanted,
bleached, and dried, are then passed through a reed, and ultimately
wound on to a warp beam or beams ready for printing or weaving.
It will be evident that by combining several processes in one machine
or apparatus, so that they may be carried on in succession, a very
considerable economy of labour will be effected. We would however
observe that some of the processes, such as either the bleaching or
mordanting, may under some circumstances be dispensed with.
