Complete Specification Left, 16th Sept., 1889-Accepted, 19th Oct., 1889
PROVISIONAL SPECIFICATION.
Improved Means of and Apparatus for Regulating the Delivery of
Yarn in Looms for Weaving.
We, FRANK WILSON of 67, Oxford Road, Burnley in the County of Lancaster,
Mill Manager, and ABRAHAM TOWLER of the same place, do hereby declare the nature
of this invention to be as follows :-
This invention is designed to provide a self-regulating motion or drag, the amount
of which varies in proportion to the decreasing diameter of the warp beam, For this'
purpose, we fix to one or both ends of the warp beam a disc or flange, to which
friction is applied by two levers, one on each side of the disc or flange. These
levers are drawn towards each other by means of a bolt, to obtain the requisite
degree of friction, and are secured to a horizontal shaft. To the same shaft is
attached another lever, the upper end of which bears against the warp on the beam,
in such a
manner, that as the yarn decreases in diameter, the friction clips or
levers will be moved towards the centre of the disc, and will therefore exert less
resistance to the delivery of the yarn, in accordance with the reduced diameter of
the yarn on the beam.

COMPLETE SPECIFICATION.
Improved Means of and Apparatus for Regulating the Delivery of
Yarn in Looms for Weaving.
We, FRANK WILSON of 67 Oxford Road, Burnley, in the County of Lancaster,
Mill Manager, and ABRAHAM TOWLER, of the same place, 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 is designed to produce a self-regulating motion or drag-for-
regulating the delivery of yarn in looms for weaving-the amount of which varies in
proportion to the decreasing diameter of the warp beam.
In the accompanying drawing A represents the warp beam to which is keyed or
otherwise fixed at one or both ends thereof a disc or flange B, friction being
applied thereto by two arms or levers C, C, one of which bears on each of the two
sides of said disc or flange. These levers-which are provided with suitable hollow
friction plates lined with leather or like material--are drawn towards each other
by means of a bolt a to obtain the requisite degree of friction, and are secured to
a horizontal shaft D. To this shaft which is suspended in bearings carried by
the arms of a suitable bracket secured to the loom rail c-is attached another lever É
the upper end of which carries a roller F bearing against the warp on the beam,
in such
a manner, that as the yarn decreases in diameter the friction clips or
levers C, C, will be moved towards the centre of the disc B and will therefore
exert less resistance to the delivery of the yarn in accordance with the reduced
diameter of the yarn on the beam.

page_text: 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 :-
The improved apparatus for regulating the delivery of yarn in looms for weaving
substantially as herein described and shown.
