Improvements in and relating to Rollers for the Spinning of Unoiled
and Untwisted Wool Fibre.
We, GEORGE MITCHELL, of Cullingworth Mills, Cullingworth, near Bradford,
in the County of York, Spinning Manager, and ARTHUR CRAVEN, of Hallas
Lodge, Cullingworth, aforesaid, Worsted Spinner, 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 the spinning of wool fibre, such, as in the prepara-
tion for spinning, has not been oiled nor received any twist in the process of
reduction to what is known as "roving," as is the case with wool fibre prepared
and reduced for spinning on throstle frames as hitherto constructed.
Our object is to arrange throstle frames in such a manner that, they may be
utilized for the spinning of unoiled and untwisted wool fibre; and in describing
our invention in detail, reference is made to the accompanying drawings in
which Fig. 1 represents a front elevation of a short length of intermediate
rollers constructed in accordance with our invention, with carriers resting upon
the same.
Fig. 2 is a cross sectional elevation through line a, b, and
Fig. 3 is a front elevation of a short length of intermediate rollers with
fluted carriers resting upon same constructed in accordance with our invention.
In carrying out our object, we utilize a cap or fly throstle frame provided
with front and back drawing rollers of the ordinary construction, and operated
in the ordinary manner, but instead of utilizing the ortuary intermediate
rollers and carriers mounted between the before mentioned rollers, we intro-
duce in the same position, fluted rollers A, driven in a suitable manner at a
speed proportionate to the surface speed of the ordinary front rollers, and upon
the said fluted rollers A, we place metallic carriers B, supported by journals C,
and driven by frictional contact with the before mentioned fluted rollers, the
journals C, are secured to saddles D, of the ordinary construction.
Instead of fluting the intermediate rollers, as hereinbefore described, our
object may be accomplished by fluting the metallic carriers B', shown by Fig. 3,
and constructing the intermediate rollers A', with a smooth circumference, the
rotation of the rollers is the same in either case, and the unoiled and untwisted
fibre passes between the said rollers and carriers in its travel from the roving
to the rotating fly spindle or cap spindle tube as the case may be; the rollers
and carriers constructed in the manner described sustain the unoiled and
intwisted fibre in its travel between the ordinary back and front rollers of the
pinning frame.
Having now particularly described and ascertained the nature of this inven-
ion, and in what manner the same is to be performed, we declare that what
re claim is;-
-
A throstle spinning frame provided with front and back drawing rollers
ombined with intermediate rollers and carriers arranged substantially in the
anner and for the purpose as hereinbefore set forth."
