APPLICABLE TO THE BOBBINS AND TUBES USED IN SPINNING MACHINERY AND
IN PREPARING AND DOUBLING MACHINERY."
Our Invention relates to the bobbins and tubes used in preparing, spinning,
doubling, and winding machinery, and has for its principal object to improve and
strengthen, such parts of the bobbins and tubes as are most liable to wear and to
become cracked or broken. Previously to our Invention metal ferules or rings
have been applied to the tubes used in the treatment of fibrous materials, but such
rings have usually been formed by casting, and consequently add greatly to the
weight of the tubes. In our Invention we strengthen the end or each end of the
tube or hobbin by means of a ring made of tin plate, sheet brass, or other thin.
metal which is stamped, pressed, or spun into form. For some purposes the ring is,
flanched at one end, and the edge of the flanch is by preference turned up,
so that when the ring is forced on to the tube or bobbin the said edge penetrates
into the wood or enters the bore a short distance. The ring is secured by spinning,.
milling, or pressing down the other edge over a shoulder or into a groove turned in
the tube or bobbin. This part of our Invention is applicable to tubes or bobbins
having round, square, partly square, or polygonal ends. When the tube or bobbin
is formed with driving slots we saw or cut through both metal and wood to form.
the slots. In another form the ring is shaped to fit on the shoulder of the bobbin

page_text: collar or on to the end of the bobbin, and is further secured by forcing or turning
down parts of the metal into the driving slots. In some forms of bobbins, tubes,
or pirns, we force into the end or into each end of the bore of the bobbin or tube a
thin metal tube which is flanched out at one end, and by preference has the end of
the fanch turned up so that it enters into the wood. In the cases of very thin
tubes, such, for example, as are used in ring spinning, we use a very light ring
which is formed into a J. L. or U shape in cross section, or into a suitably stiff form.
We enlarge the bore at the end of the tube for a short distance, and force the ring
into this enlargement, and then fill up the enlarged bore from the ring to the end
of the tube with a wooden ferule or bush. In some cases we apply a thin ring
externally, and secure it by spinning or pressing down one or both edges into a
groove, and in some cases or in any case we further stiffen the tube by forcing a
thin metal tube into position at about the centre of the length of the bore.

by the said Joshua Henry Wilson and Lawrence Wilson in the Great Seal
Patent Office on the 25th October 1881.

APPLICABLE TO THE BOBBINS AND TUBES USED IN SPINNING MACHINERY AND
IN PREPARING AND DOUBLING MACHINERY."
Our Invention relates to the bobbins and tubes made of wood, paper, and other
material, and used in preparing, spinning, doubling, and winding machinery, and
has for its principal object to improve and strengthen such parts of the bobbins
and tubes as are most liable to wear and to become cracked or broken. Previously to
our Invention metal ferules or rings have been applied to the tubes used in the
treatment of fibrous materials, but such rings have usually been formed by casting,
and consequently add greatly to the weight of the tubes, besides being subject in
other serious objections. In our Invention we strengthen the end or each end of
the tube or bobbin by means of a ring preferably made of tin plate, sheet brass, or
other thin metal which is stamped, pressed, or spun into form. For some purposes
the ring is flanched at one end, and the edge of the flanch is turned up so that
when the ring is forced on to the tube or bobbin, the said edge penetrates into the
wood or other substance composing the tube, or enters the bore a short distance.
The ring is further secured by spinning, milling, or pressing down the other edge
over a shoulder or into a groove turned in the tube or hobbin. In the cases of
very thin tubes, such, for example, as are used in ring spinning, we use a very light
ring which is formed in a J. L or U shape in cross section, or into other suitably
stiff forms, as hereinafter specified. We enlarge the bore at the end of the tule
for a short distance and force the ring into this enlargement, and then fill up the
enlarged bore from the ring to the end of the tube with a wooden ferule or bush.

page_text: And in order that our said Invention may be properly understood, we will now
proceed more particularly to describe and ascertain the same, reference being had
to the annexed Sheet of Drawings and to the letters and figures marked thereon.
ln
Fig. 1 is a sectional view of an ordinary press intermediate slubbing or roving
tube to which our Invention is shewn applied. The ring a at the foot of the tube
is made of tin plate, sheet brass, or other light metal, and is formed in any suitable
manner into the required shapes. In the example shewn the ring is Hanched at
the lower end, the outer edge of the flanch being turned up so as to enter the bore
of the tube for a short distance. To secure the ring in position, the upper edge is
milled or pressed over a shoulder on the tube, which prevents it from being
withdrawn. The driving slots may be sawn or cut through both the metal and
the material of the tube, or, if preferred, the slots may be cut in the tube previous
to the application of the ring, and portions of the ring be pressed or folded down
into the driving slots. The upper end of the tube is or may be provided with a
similar ring c. Fig. 2 is a sectional view of a similar tube, wherein the upturned
portion of the flange on the ring a is forced into the substance of the tube end,
instead of entering the hore, as described and shewn with reference to Fig. 1.
both of these examples a shoulder. is shewn on the outside of the lower end of the
tube, over which shoulder the edge of the ring can be bent or milled. Fig. 3 shews
a tube formed without such shoulder, and having the edge of the ring milled or
pressed against or into the material of the tube or into a groove formed for its
reception. Fig. 4 is a view of part of a tube shewing the lower end hexagonal in
form, and to which a similarly formed metallic protector is applied in the manner
set forth. Our Invention is applicable to any other polygonal form of tube end.
Fig. 5 is a view of a tube having the rings a inserted into the bore instead of being
outside, as hereinbefore described, Fig. 6 being a modification of the same appli-
cation of our Invention. In Fig. 5 the upturned edge of the flanch is forced into
the material of the tube. In Fig. 6 the edge prolonged and surrounds the outside
of the tube. In Fig. 6ª the upturned edge is dispensed with and the ring is of an
L shape. In some or in all cases where the ring is applied to the inside of the
tube, we may secure the ring by milling or pressing the upper edge thereof into
the side of the bore or into a groove cut to receive it, as shewn at Fig. 7, or we
may groove the ring, as shewn at Fig. 8, spirally or otherwise, or punch, indent,
notch, or pin, or tement it in after it has been placed in position or during the
process, so as to cause adhesion between the ring and the bore of the tube. Similar
means may also be employed to secure the exterior rings and ferules. Fig. 9 shews
a portion of a tube having a U shaped ring a sunk into the end. Fig. 10 shews
the lower end of a tube having a ring introduced into the bore in the manner
indicated. The contracted portion of the bore is enlarged at the foot for a certain
distance upwards, so as to admit the flanched ring, and when the ring has been
fixed in position the enlarged part of the bore is filled up by an annular plug e
which retains the ring in position. Fig. 11 represents in section the lower end of
a warping or winding or other similar bobbin provided with a busb d, to which a
ring shield is applied in a manner similar to that shewn at Fig. 5. Fig. 12 is a
similar bobbin fitted with a projecting or pivot bush. The principal object of
the ring or shield in the latter two Figures is to protect the bush from injury.
Fig. 13 is a sectional view of a long collar spinning or doubling bobbin, into the
bore of which is inserted and secured the J form of ring. Fig. 14 is a spinning or
doubling bobbin with ring applied. The remaining Figs. illustrate the tubes
and bobbins employed in ring spinning and doubling. Fig. 15 is a view of a
hobbin, to the foot of which a J shaped ring a is applied. Fig. 15 shews a straight
ring, and Fig. 15h an L shaped ring. Fig. 16 is a cop or pirn bobbin similarly
fitted. In Figs. 17, 18, 18, 19, 20, and 21, the rings are all introduced for a certain
distance into the bore in the manner already described with reference to Fig. 10,
that is to say, the bore is first enlarged and the ring forced or slipped into position,
the enlargement being afterwards filled up by an annular plug. In Fig. 17 the
ring is of a J form; in Fig. 18 of an L form; in Fig. 19 of a U form; in Fig. 20 of

page_text: a H form; and in Fig. 21 of a T, form. In Fig. 18ª a straight ring is shewn. In
some cases and with the object of strengthening the tubes against compression, we
force one or more thin metal tubes into position at or about the centre of the length
of the bore, as shewn in Fig. 15. The said thin metal tubes may also be employed
in lieu of some of the forms of rings herein before described as applied to the press
tubes, in which case they might be secured in position by indenting, grooving,
cementing, or pinning in the manner described with reference to Figs. 7 and 8.
Although we prefer to form the rings, hoops, shields, and ferules from sheet
metal, some of them may be malleable castings, and we therefore do not confine
ourselves to the methods of producing the said rings, hoops, shields, and ferules, so
long as they are made of the novel forms and applied in the novel manners set
forth and indicated, but what we consider to be novel and original, and therefore
claim as our Invention is as follows:-
Firstly. Strengthening and protecting the bobbins and tubes used in preparing
spinning and doubling machinery by the application thereto of thin metallic
ferules, hoops, and shields formed and applied, substantially as herein before
described and shewn.
Secondly. The hoops, shields, and ferules applied to press, slubbing, intermediate;
and roving tubes, as set forth, and having the driving slots sawn or cut after
application, substantially as set forth and indicated.
Thirdly. Applying hoops, shields, and ferules of the indicated forms to the
exterior of tubes and bobbins in such a manner as that the upturned edge of the
flanch shall either enter the bore of the tube for a short distance or enter
the material of the tube, as herein before described and shewn.
Fourthly. The application of the internal metallic rings, hoops, and ferules of
the indicated forms, either with or without flat or upturned flanches, to tubes and
bobbins, substantially as herein before described and shewn.
And, Lastly, the application of flanched and hollow rings, hoops, and ferules to
the interior of bobbins, the said rings and ferules being partially concealed by
annular plugs, substantially as described and shewn.

of the said Joshua Henry Wilson, have hereunto set my hand and seal,
