COMPLETE SPECIFICATION.
Shields for Bobbins and the like..
1 CURSETJEE NOWROZJEE WADIA of Cumballa Hill, Bombay, India,
Consulting Engineer, 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 said invention relates to means for rendering more durable tubes, skewers,
bobbins and the like, used for holding fibrous substances in the various operations
to which such substances are subjected whether in the process of preparing and
spinning into yarn or in subsequent manipulation or treatment, or for wire
working, rope making, or other purposes in which threads or wires in a wound
state are employed.
In my invention I strengthen one or both ends of the tube or bobbin by means
of a corrugated ring made of tin plate, sheet brass, or other thin metal stamped,
pressed, spun or otherwise fashioned to the required form.
The ring is secured by spinning, milling, pressing, burnishing or bracing
down into a groove or grooves which may be previously turned in the tube or
bobbin.
In order that my invention may be more clearly understood I will describe the
same with reference to the accompanying drawings.
Figure 1 is a view half in section of an ordinary press (slubbing, intermediate
or roving) bobbin to which my invention is applied externally. The corrugated
shield a at foot of the tube is made of tin plate, sheet brass or other light metal
and is formed in any suitable manner to the required shapes. To secure the
shield in position it is pressed over and milled down into hollow grooves which
have been previously turned in the head or ends of the tube.
The upper end is or may be provided with a similar ring b.
In Figure I a shoulder is shown on the outside of the lower end of the tube.
Figure II shows a tube formed without such shoulder and having the grooves
milled into the tube as before.
Figure III depicts a similar bobbin but with the shield applied on the inside or

page_text: My invention is applicable to any polygonal form of tube end as well as to tubes
with cylindrical or conical ends.
Figure IV is a section of a spinning or doubling bobbin to which a corrugated
ring shield a has been applied in the manner previously set forth.
The remaining figures illustrate various types of tubes and bobbins employed in
ring spinning.
Figure V represents a taper ring spinning bobbin in which the ring is secured
by being pressed into a groove at the upper edge of the ring.
Figure VI represents a similar bobbin with two grooves pressed in on the
outside.
Figure VII is a modification by using a narrow ring only in which only the
concave part of a corrugation is present.
In Figure VIII the ring is shown internally applied.
Figure IX shows a shield covering the head of the bobbin and having only the
concave part of a single corrugation.
Although I prefer to form rings, hooks, shields and ferrules fashioned from
sheet metal they may be produced in other ways for example malleable castings
may be used and I do not confine myself to any particular method of manufacturing
the said rings, hooks, shields, ferrules or the like so long as they are made of the
corrugated forms and applied as set forth.
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. The method of strengthening and protecting bobbins, tubes, skewers used in
preparing spinning and doubling machinery by application thereto of thin corru-
gated metallic ferrules, hooks or shields formed and applied substantially as
hereinbefore described and shown.
2. Corrugated hooks, shields or ferrules applied to press (slubbing, intermediate
and roving) bobbins and tubes substantially as set forth and indicated.
3. The use of corrugated internal metallic rings, hooks or ferrules applied to
tubes and bobbins substantially as hereinbefore described and shown.
Dated this 23rd day of April 1892.
