Complete Specification Left, 25th Oct., 1893-Accepted, 25th Nov., 1893
PROVISIONAL SPECIFICATION.
Improvements in or applicable to Ring Frame Bobbins.
We, THOMAS WHITELEGG of Water Lane, Wilmslow, Cheshire, Spinning
Manager, and WILLIAM SKERRATT, of 160 Barton Lane, Eccles, Lancashire,
Engineer, do hereby declare the nature of our said invention to be as follows:-
Our invention relates to ring frame bobbins and consists in the application of a
thimble or cap of metal to the tip or nose of the hobbin to prevent the abrasion
and wearing away of the substance of the bobbin by the yarn and so increase the
durability of the bobbin and cause better yarn to be produced and prevent the
production of "snarls" and waste of yarn arising from imperfect or worn bobbins.
The metal shield or thimble is made of by preference stamped steel or brass and
as light as possible and shaped to the general form of the tip of the bobbin. The
thimble is pressed on to the bobbin which may be necked down to receive it. The
thimble may be more perfectly affixed by indenting the thimble from the outside
into the substance of the bobbin after the manner of fixing an umbrella ferrule.

COMPLETE SPECIFICATION.
Improvements in or applicable to Ring Frame Bobbins.
We, THOMAS WHITELEGG of Water Lane, Wilmslow, Cheshire, Spinning
Manager, and WILLIAM SKERRATT of 160 Barton Lane, Eccles, Lancashire,
Engineer, do hereby declare the nature of our said invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
Our invention relates to twist ring frame bobbins and consists in the application
of a thimble or cap of metal to the tip or nose of the bobbin to prevent the
abrasion and wearing away of the substance of the bobbin by the yarn and so
increase the durability of the bobbin and cause better yarn to be produced and
prevent the production of "snarls" and waste of yarn arising from imperfect or
worn bobbins.
And in order that our said invention shall be the more readily understood and
carried into practical effect we have hereunto annexed a sheet of drawings illus-
trative of the same and will now proceed to describe the same with the assistance
of the various figures and letters of reference marked thereon.
Fig. 1 is an exterior view of a twist ring frame bobbin with our improved
protector shewn applied thereto.
Fig. 2 is a similar view of a twist ring bobbin without the protector and shewing
the way in which the tip or nose of the bobbin is prepared to receive the
protector.
Fig. 3 is a sectional view of Fig. 1 and
Fig. 4 illustrates the protector separately.
(A) designates the protector which is made of, by preference stamped steel or
brass and as light as possible and shaped to the general form of the tip (B) of the
bobbin (C). In applying it to the bobbin the protector is forced onto the bobbin
and is caused to lie flush with the outside of the bobbin by reason of the tip (B)
being necked down as illustrated in Fig. 2.

page_text: The protector is best fixed on the bobbin by indenting it as illustrated in
Fig. 1 after the manner of fixing an umbrella ferrule.
Having thus particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we would point out that
the distinctive feature of our invention is the application of a metal or other
similar protector to a twist ring frame bobbin for preventing "snarls" in the yarn
and to preserve the bobbin ends and what we desire to secure by Letters
Patent is.-
The application of a metal or other similar tip or ferrule to twist ring frame
bobbins substantially as and for the purposes herein before described and illustrated
on the accompanying drawing.
