Complete Specification Left, 26th Aug.. 1890-Accepted, 27th Sept., 1890
PROVISIONAL SPECIFICATION.
Improvements in Ring-frame Bobbins.
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 invention has reference to the bobbins used on ring spinning and doubling
frames and has for its object the strengthening of the hoops or bosses applied to the
lower end of such bobbins, thereby improving the bobbin and greatly increasing its
durability.
This invention relates to the hoop or boss, known as Southwells patent boss applied
to ring throstle bobbins. These bosses are made by being pressed or stamped out of
thin sheet brass, steel, or other metal. My improvement is attained by retaining a
small flange of the same metal projecting from the top of the taper of the boss or
hoop, in the process of stamping. That part of the bobbin I enlarge to suit the
diameter of the metal flange, and when the boss is applied to the end of the bobbin,
it can be secured on the bobbin, by the edge of the flange being milled over the
enlarged part of the bobbin, or, by the metal of the boss being punched into the
bobbin..

COMPLETE SPECIFICATION.
Improvements in Ring-frame Bobbins.
I, JOSHUA HENRY WILSON of Cornholme near 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 invention has reference to the bobbin used on ring spinning and doubling
frames, and has for its object the strengthening of the hoop or boss applied to the
lower end of such bobbins, thereby improving the bobbin and greatly increasing its
durability.
This invention relates to the hoop or boss, known as Southwells patent boss, applied
to ring throstle bobbins.
These bosses are made by being pressed or stamped out of thin sheet brass steel or
other metal. My improvement is attained by retaining a small flange of the same
metal projecting from the top of the taper of the boss or hoop, in the process of
stamping. That part of the bobbin I enlarge to suit the diameter of the metal flange,
and when the boss is applied to the end of the bobbin it can be secured on the bobbin
by the edge of the flange being milled over the enlarged part of the bobbin, or by the
metal of the boss being punched into the bobbin.
In the accompanying sheet of drawings
Figure 1 represents a bobbin with my improved hoop or boss on it.
Figure 2, represents a similar bobbin, shewing the part with the hoop on it in
section.
Figure 3, represents a hoop in section before putting it on the bobbin.
a represents the bobbin, 6 the boss or hoop, c the flange of the hoop, d the enlarged
part of the bobbin to fill the flange of the boss and over which the flange is shewn at
Fig. 2 as milled to secure the boss on the bobbin. When the flange is not milled

page_text: over the enlarged part of the bobbin, the boss is secured in its place by the metal of
the boss being punched into the bobbin in the manner well known.
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 what I
claim is
Applying hoops or bosses to the lower end of ring frame bobbins, having a flange
made at the top of the hoop so as to clip or cover an enlarged part made on the
bobbin, in the manner and for the purpose described.
