PROVISIONAL SPECIFICATION.
Improvements in Bobbins used for Spinning and Twisting Frames.
I, JOSHUA HENRY WILSON of Cornholme Todmorden in the County of
Lancaster, Bobbin Manufacturer, do hereby declare the nature of this invention to
be as follows:-
My improvements have reference to bobbins used in spinning and twisting
frames where the bobbins are driven by projections attached to or forming part of
the spindles, & which go into recesses in the lower end or flange of the bobbin for
the purpose of driving. These recesses may be two or four, and radiate from the
centre of the bobbin. They are liable when unprotected to wear by the action of
the projections of the spindle on the wood of the bobbin. My invention consists in
applying a protector to the recesses in the bobbin, (of a simple and effective con-
struction), which I make out of sheet metal stamped into shape into two or four
oblong parts, to fit in the recesses of the bobbin, the inside to admit easily the
projections on the spindle. The ends of the oblong parts of the projector are left
open, and bent outwards, and the bent parts cut or shaped into the form of a spike
or nail. The centre part of the protector may be inserted into a groove cut in the
bottom of the bobbin.
When putting the protector into its place the spikes at the end of the oblong
parts are driven into the wood, thus keeping the protector secure in its place.
Dated this 13th day of May 1891.

COMPLETE SPECIFICATION.
Improvements in Bobbins used for Spinning and Twisting Frames.
I, JOSHUA HENRY WILSON of Cornholme Todmorden in the County of
Lancaster Bobbin Manufacturer 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:—
My improvements have reference to bobbins used in spinning and twisting
frames where the bobbins are driven by projections attached to or forming part of
the spindles and which go into recesses in the lower end or flange of the bobbin
for the purpose of driving. These recesses are liable when unprotected to wear by
the action of the projections on the wood of the bobbins.
My invention consists in applying a protector to the recesses in the bobbin-of
a simple and effective construction-which I make out of sheet metal stamped into
shape, with two or four oblong parts to fit in the recesses of the bobbin, the inside
to admit easily the projections on the spindle.
The centre part of the protector may be inserted in a groove in the bottom of
the bobbin. The ends of the oblong parts are left open and a spike cut out or
formed at their ends; they are left sufficiently long to admit of being bent outwards
for a short distance for the purpose of the spikes being driven into the solid wood

page_text: when inserting the protector in its place, thus securing the protector in the
bobbin.
If the flange of the bobbin is large enough in diameter the ends of the oblong
part may be left straight, but their full length.
In the accompanying sheet of drawings the same letters refer to the same parts
as shewn in the different figures.
Figure
represents the bottom end, of the flange of a bobbin with a protector,
having two oblong parts.
.
Figure 2 represents a bobbin shewing an end view of the protector in its place
in the bobbin flange part of the wood being broken off for the purpose.
Figure 3 a section view across the circular part and
Figure 4 a section view lengthways of the protector as shewn at Fig. 1.
Figure 5 a side view of the protector.
Figure 6 represents the bottom end of the flange of a bobbin with a protector
having four oblong parts.
a is the bobbin, the bobbin flange, c the protector, d the part of the protector
plate which connects the two sides of the protector, the bent part of the end of
the oblong parts of the protector on which is cut or formed the spikes or nails,
f the spikes.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that I am aware
that it has been previously proposed to employ metal protectors for the purposes
above stated and I wish it to be understood that I lay no claim. to metal protectors
as such, but what I claim is-
Applying sheet metal protectors to the ends of bobbins having the oblong parts
left open, and a spike formed at their end in the manner and for the purpose as
shewn and described.
