Luke Stott at the Office of the Commissioners of Patents, with
their Petition, on the 8th March 1872.
We, MORGAN BRIERLEY, of Rochdale, in the County of Lancaster,
Flannel Manufacturer, and FREDERICK LUKE STOTT, of the same Place,
Machine Maker, do hereby declare the nature of the said Invention for
" IMPROVEMENTS IN THE MANUFACTURE OF YARNS OR THREADS FORMED OF MIXED
COTTON AND ANIMAL WOOL," to be as follows:-
:-
Hitherto the ordinary method of manufacturing mixed cotton and
animal wool yarns or threads has been by spreading layers of wool and
oiling them with alternate layers of cotton, and then passing the mixed
materials through a "willow" or opener, then through a "scribbler," from
which the carded material is taken in a rolled or twisted sliver and
folded in a diagonal zig-zag lap to feed into the carding engine. There
are objections to this process, inasmuch as the oil intended for the wool
alone gets mixed with the cotton in passing through the "scribbler,"
which having to act upon the mixed fibres is overworked as compared
with our improved process herein-after described by having to operate
upon both materials, and performs the work less satisfactorily than by

page_text: our improved process, which incorporates the cotton and animal wool
fibres in such manner that all the subsequent processes are carried on
with less labour and the yarn or thread produced is more even, strong,
and perfect than by the ordinary process of manufacture, even when
inferior materials are used.

Our improved manufacture of yarns or threads of mixed cotton and
animal wool relates to the preparatory process. We prepare the cotton
fibre and card, and get it into the form of a "sliver" just as it is treated
when intended for cotton yarn or thread. The sliver may, if preferred;
be passed several times through an ordinary drawing frame, and may
either have a little twist or be without twist, and may be placed or "coiled"
in a can or other receptacle or wound on a bobbin. The wool is
subjected to the usual and ordinary processes-for manufacturing wool by
itself, and is passed through the scribbler by itself. The sliver of cotton
is drawn from the "can or bobbin placed on one side of the scribbler
and across the delivery end thereof, passing through the ordinary appa-
ratus for giving twist to the sliver from the scribbler, and from this
twisting apparatus the cotton sliver passes to the diagonal zig-zag lap
forming apparatus of the. ordinary carding engine. Thus arranged the
'cotton sliver with its fibres longitudinal acts as a core, and the carded
animal wool as delivered from the scribbler is wound round it as it
passes along to the carding engine, the wool fibres being mostly across
those of the cotton sliver. The combined sliver is fed in the ordinary
diagonal zig-zag manner, and it is subsequently treated by all the
ordinary processes for making yarn or thread of mixed cotton and
animal wool. The bobbin or can containing the cotton fibre may
be rotated as the sliver is delivered to twist and wind the carded animal
wool round it, or this rotation of the " can may be given to assist the
action of the ordinary twisting apparatus.
