Improvements in Means for Strengthening and Protecting Tubes
and Bobbins Used in the Preparation and Spinning of Fibrous
Materials.
I JOSHUA HENRY WILSON of the Firm of Wilson Brothers Limited, of the
Cornholme Bobbin Works, Todmorden, in the County of Lancaster, Bobbin,
Manufacturers, do hereby declare the nature of this invention to be as follows:-
My said invention relates to improvements in and in the application of light
metal rings or shields for strengthening and protecting tubes and bobbins used in
the preparation and spinning of fibrous materials as is well understood.
Generally speaking my invention consists in taking a suitable length or strip of
thin sheet metal, made of such a shape in cross section, that when pressed into a
groove or grooves made to receive it in the material of the bobbin, the metal strip
is expanded as to its breadth and the edges of the strip are forced into the sides
of the groove or grooves so as to take a firm hold and remain thus locked in
position.
For example when applying my invention to an ordinary tube or bobbin, I take
such a strip of thin sheet metal as I have described and bend it as to its breadth so
as to make it in cross section of a curved or semi-circular or angular or trough or
other suitable shape or the strip might be corrugated, the object in all cases being
to provide sufficient material in the breadth of the strip to enable it to expand or be
more or less flattened out when pressed or milled into its place. The edges of this
strip might be plain or they might be notched or serrated or roughened either
continuously or at intervals so as to enable the edges to take a better hold. I then
turn a groove or grooves in the bobbin at the point where it is intended to apply
the ring, the groove being of just sufficient width to admit the strip before being
pressed down or flattened. I then apply the strip and roll it into the groove or
grooves, applying a milling and pressing tool to the back of the strip so that it is
pressed in the form of a ring into the groove. The pressure on the back tends to
flatten down the section of the strip and expands or pushes outwards the edges
which are thus thrust or sprung into the sides of the groove, and remain fixed or
locked therein so that the ring cannot be removed or can only be removed with
difficulty.
The joint between the two ends of the ring strip might be soldered or caused to
overlap or be fixed by nails if such further security should be thought necessary or
desirable.
These rings might be applied at the foot or at the head of the bobbin and might
be used for the interior as well as for the exterior of such bobbins and tubes.

Improvements in Means for Strengthening and Protecting Tubes
and Bobbins Used in the Preparation and Spinning of Fibrous
Materials.
I JOSHUA HENRY WILSON of the Firm of Wilson Brothers Limited, of the
Cornholme Bobbin Works, Todmorden, in the County of Lancaster, Bobbin
Manufacturers, 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 and accompanying drawings
._
My said invention relates to improvements in and in the application of light
metal rings or shields for strengthening and protecting tubes and bobbins used in'
the preparation and spinning of fibrous materials as is well understood.
Generally speaking my invention consists in taking a suitable length or strip of
thin sheet metal, made of such a shape in cross section, that when pressed into a
groove or grooves made to receive it in the material of the bobbin, the metal strip
is expanded as to its breadth and the edges of the strip are forced into the sides
of the groove or grooves so as to take a firm hold and remain thus locked in
position.
My invention will be more clearly understood by a reference to the annexed
sheet of illustrative drawings.
Fig. 1 is an external view of a bobbin having my improved strengthening ring
applied at the foot.
The remaining enlarged sectional views Figs. 2 to 6 illustrate the improved ring.
and the mode of applying the same.
.
The ring on the tube a. Fig. is marked .b.and it is formed and applied in the
following manner. I take such a strip of thin sheet metal as I have described and
bend it as to the breadth (see Fig. 2) so as to make it in cross section of a curved
or semi-circular shape, the object being to provide sufficient material in the
breadth of the strip 6 to enable it to expand or be more or less flattened out when
pressed or milled into its place. The edges of this strip might be plain or they
might be notched or serrated or roughened either continuously or at intervals so as
to enable the edges to take a better.hold. I then turn a groove in. the bobbin a
(see Fig. 3) at the point where it is intended to apply the ring 6 the groove being
of just sufficient width to admit the strip before being pressed down or flattened. I
then apply the strip as shown at Fig. 4 and roll it into the groove, applying a
milling and pressing tool to the back of the strip b so that it is pressed in the form
of a ring into the groove. The pressure on the back tends to flatten down the
section of the strip, (see Fig. 5) and expands or pushes outwards the edges, which
are thus thrust or sprung into the sides of the groove as clearly appears in Fig. 5
and remain fixed or locked therein so that the ring cannot be removed or can only
be removed with difficulty.
Fig. 6 is a complete section showing the ring 6 fixed in position.
The joint between the two ends of the ring strip 6 might be soldered or caused
to overlap or be fixed by nails if such further security should be thought necessary
or desirable.
Although I have described the ring strip bs bent into a curved or semi-circular
shape, the said ring strip might be bent into an angular or trough or other shaped
section, or it might be corrugated, the object in all cases being to provide sufficient
material in the breadth of the strip to enable it to expand or be flattened out when
pressed or milled into position. Any number of these rings or bands might be
applied.
These rings might be applied at the foot or at the head of the bobbin and might
be used for the interior as well as for the exterior of such bobbins and tubes.

page_text: 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.
As means for strengthening and protecting tubes and bobbins used in the
preparation and spinning of textile fibres, the embracing ring or band 6 made from
a strip or portion of thin metal and bent or formed to such a shape in cross section
as will permit of its being easily inserted and flattened down in a groove formed to
receive it in the external or internal circumference of the bobbin or tube, the edges
of the said strip, band or ring being forced into the edges of the groove in such a
manner as to hold the strip, band or ring in position, substantially as hereinbefore
described and as illustrated.
