PROVISIONAL SPECIFICATION.
Improvements in Means for Strengthening and Protecting Tubes
and Bobbins Used in the Preparation and Spinning of Fibrous
Materials.
I HERBERT WILLIAM WILSON of Wilson Brothers Limited of Cornholme,
Todmorden, in the County of Lancaster, Bobbin Manufacturers, do hereby
declare the nature of this invention to be as follows:-
-―
My said invention refers to an improved method of forming, and applying the
light metallic rings, hoops, ferrules and shields which it is now the practice to place
upon tubes and bobbins used in textile machinery.
Under an invention for which I have obtained Her Majesty's Letters Patent
No. 18790 of 1891, I made such rings and hoops with a projecting flange, edge or
lip standing at about right angles to the body of the ring or hoop, the said flange,
lip or edge being pressed into a groove preferably cut in the wooden tube or bobbin
to receive it.
My present invention is for similar objects but instead of forming the metallic
hoops or rings with the said penetrating flange or lip I fold or double over the
lower part of the hoop thus presenting a flat raised band at the foot of the interior
of the hoop.
When the hoop is applied to a tube or bobbin or flange I press this raised
folded edge into the wood of the bobbin or tube the pressure being sufficient to
bury the folded edge in the wood, the edge of the doubled over portion thus serving
as a confining ring to prevent the hoop from coming off. The upper edge of
the hoop is formed as set forth in my foregoing Patent or in any other
convenient or suitable manner so as to engage with or lay hold of the tube or bobbin
or flange.
I have found that the folded over edge gives a perfectly secure holdfast to the
hoop and obviates many difficulties that occur in applying the, said metal hoops
under my aforesaid former Patent of 1891.
It is not necessary to groove or recess the wood of the bobbin or tube to receive
the folded edge as pressure. alone suffices to sink the latter into the solid wood,
where it remains as a binding and securing ring. The rounded lower edge of the
folded over foot of the hoop being smooth and polished, there is no sharp edge to
cut or catch the yarn while the doubled edge increases the strength and rigidity of
the hoop. My improvement can be applied in conjunction with hoops, ferrules,
shields and rings of all descriptions and for all types of tubes, pirns and bobbins
that admit of its application.

I HERBERT WILLIAM WILSON of Wilson Brothers Limited, of Cornholme,
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 refers to an improved method of forming and applying the
light metallic rings, hoops, ferrules and shields which it is now the practice to place
upon tubes and bobbins used in textile machinery.
Under an invention for which I have obtained: Her Majesty's Letters Patent
No: 18790 of 1891, I made such rings and hoops with a projecting flange; edge or
lip standing at about right angles to the body of the ring, or hoop, the said flange,
lip or edge being pressed into a groove preferably cut in the wooden tube or bobbin
to receive it.
My present invention is for similar objects but instead of forming the metallic
hoops or rings with the said penetrating flange or lip I fold or double over the
lower part of the hoop, thus presenting a flat raised band at the foot of the interior
of the hoop.
When the hoop is applied to a tube or bobbin or flange I press this raised
folded edge into the wood of the bobbin or tube, the pressure being sufficient to
bury the folded edge in the wood, the edge of the doubled over portion thus
serving as a confining ring to prevent the hoop from coming off. The upper edge
of the hoop is formed as set forth in my foregoing Patent or in any other
convenient or suitable manner so as to engage with or lay hold of the tube or bobbin
or flange.
In order that my invention may be more clearly understood I will now proceed
to describe the same in greater detail with the assistance of the annexed sheet of
drawings.
Fig. 1. is a sectional view of my improved metallic strengthening ring or ferrule
before application to a tube.
Fig. 2. shows the same applied to the tube but before being pressed down
and fixed.
Fig. 3. shows the ring or ferrule pressed down and fixed on the tube.
Fig. 4. shows my improved ring applied to the interior of the foot of a ring
spinning bobbin, while
Fig. 5. shows the same applied to the exterior of a similar bobbin.
Figs. 6 and 7. illustrate the application of my improved strengthening ring to
the flanges of a bobbin.
I form the metallic ring a as shown in Fig. 1 with a downwardly projecting
flange or lip a¹ as in my said former Patent and intended to enter the wood of the
tube at the top. At the foot of the ring I fold or double over the margin inwards
so as to present a flat raised band a 2. The ring thus formed is now applied to the
top of the tube b as shown in Fig. 2. the flange a¹ being pressed into the material
of the bobbin at the top. I then mill or press inwards the lower part of the
ring a so as to bury the folded edge a 2 in the wood of the bobbin. The ring a is
thus held at two points, viz. by the flange a¹ and the lip a 2 so that it cannot come
off. Instead however of the flange a¹ I might provide the ring a with any other
suitable holding means at the top.
In Fig. 4 I show the ring a applied at the foot of a ring spinning bobbin b and

page_text: to the interior thereof. The upper edge a 2 of the ring a is folded over as shown
and is pressed or sunk into the wood of the bobbin 6 the lower flange a having
been previously forced into the foot of the bobbin. In Fig. 5 I show a similar
ring similarly applied to the exterior of the bobbin foot.
Figs. 6 and 7 illustrate the application of my improved ring a to a flanged
bobbin . In this instance I make both edges a 2 folded over or doubled as shown
in Fig. 6 which is a separate sectional view of the ring.
In applying the ring to the flange 62 of the bobbin, I mill, press or force these
folded edges a into the upper and inner sides of the flange b2 the sunk in edge a¹
shown in the other figs. not being required although I do not debar myself from
using it if I should think fit. This double lipped ring might be applied to other
forms of tubes and bobbins..
I have found that in these and in other similar applications of the ring a to
tubes and bobbins the folded over edge a 2 of the ring or hoop a gives a perfectly
secure holdfast to the hoop and obviates drawbacks which occur in applying the
said metal hoops under my aforesaid former Patent of 1891. For example it is
not necessary to groove or indent the wood of the tube or bobbin to receive the
folded edge a 2, as pressure alone suffices to sink the latter into the solid wood
where it remains as a binding and securing ring. The rounded lower edge of
the folded over foot of the hoop being smooth and polished there is no sharp edge
to cut or catch the yarn while the double edge increases the strength and rigidity
of the hoop.
My improvement (videlicet the folded over edge or lip) is applicable in conjunction
with all descriptions of hoops, ferrules, shields and rings of this nature for
application to all types of tubes, bobbins, bobbin flanges and pirns admitting of
such application.
.$
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.
1. In rings, hoops, shields and ferrules for application to tubes, bobbins, pirns,
and flanges for the purpose of protecting and strengthening the same, forming
the said rings, hoops, shields and ferrules with a folded or doubled over edge or
lip such as a 2 which is pressed into the wood or material so as to hold the ring
or hoop securely, in conjunction with a flange or lip a' at the other end or edge of
the ring or ferrule substantially as described and shown.
2. In rings, hoops, shields and ferrules for application to tubes, bobbins, pirns
and flanges for the purpose of protecting and strengthening the same, forming
the said rings, hoops, shields, or ferrules a with folded or doubled over edges or
lips a 2 which are both pressed into the wood or material so as to hold the ring
or hoop securely, substantially as described and as shown.
3. The improved rings or ferrules for application to tubes and bobbins substan-
tially as described and as illustrated.
