IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR SPINNING AND TWISTING FIBRES
Year: 1885

page_text: We WILLIAM BLACKBURN Worsted Spinner and SAMUEL BLACKBURN Foreman
Mechanic both of Clarence Mills and Brook Mills Cleckheaton in the county of
York, do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE METHOD OF AND APPARATUS FOR SPINNING AND TWISTING FIBRES 33 to be as
follows:-
The object of this invention is to give a long traverse, and so use long bobbins
also to insure a regular twist in spinning and twisting fibres, and to take up the
bands automatically as the spindles rise and fall, also to deliver the bands on to
the wharles in a direct straight line.
I employ two loose pulleys for each spindle, between the tin cylinders and the
wharles, the bands running under and over the pulleys, respectively each of the
pulleys are carried by a forked lever, which is pivotted on a second pivotted lever,
which is carried by a rail, the other end of the fork lever carries an adjustable or
compensating weight acting automatically to regulate the balance of the fork and
pulleys, the other end of the second pivotted lever carries an adjustable balance
weight acting automatically; when the lifter rail and spindle is in the centre of
its lift the pulleys take up the slack of the bands, by moving nearer the tin
cylinder, by means of the second pivotted lever; the pulleys are self lubricating,
the studs being hollow and split, or perforated and contain a fibrous material
which is saturated with lubricant; or the fork and pulleys may be pivotted on a
shaft, and the tin cylinder carried on pivotted bearings.

Fig. 1 shews an elevation of spinning frame with our improvements attached.
Figs. 2 and 3 shew details of self-lubricating pulley.
We employ two loose pulleys A, A, for each spindle B, between the tin cylinder D,
and the wharles E, the bands running under and over the pulleys respectively each
set of the pulleys are carried by a forked lever F, which is pivotted on a second
pivotted lever H, which is carried by a bar or rail J, the other end of the fork
lever carries a compensating weight Л, adjustable by the slot K, and screw L, or
other suitable means, acting automatically to regulate the balance of the fork and
pulleys: the other end of the second pivotted lever carries a balance weight at its
end M, acting automatically when the lifter rail and spindle tube is in the centre
of its lift, the pulleys take up the slack of the bands, by moving nearer to the tin
cylinder by means of the second pivotted lever. When a band breaks the lever H,
moves forward as shewn in dotted lines, and is prevented from coming in contact
with the cylinder by means of the flat bar J, by means of the second pivotted
lever; the pulleys A. A are self lubricating, the studs N being hollow and split or
perforated, and contain a fibrous material which is saturated with lubricant, or
the fork and pulleys may be pivotted on a shaft if preferred in lieu of the bar J.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
1. The pivotted automatic balance levers, with pulleys for taking up the slack of
the bands as shewn and described.
2. The self lubricating pulleys as and for the purposes shewn and described.
