Improvements in Bobbins.
We, FRANK LAWSON and JOHN HENDERSON, both of Jubilee Mills, Dalbeattie,
in the County of Kirkcudbright, Bobbin Makers, do hereby declare the nature
of our invention to be as follows:-
This invention has reference to and comprises improvements in bobbins of the
class formed of a barrel or body part having two disc ends secured on same, and
usually employed for holding thread or yarn and has for its object the securing
of these ends so that any tendency to come off is obviated.
In carrying into practice the improvements of this invention the barrel part is
made much as usual, having its extremities turned to a smaller diameter so as to
form a shoulder on which smaller part the bobbin end is secured. A small
groove, however, is formed around each barrel close to each extremity.
Each bobbin end has the usual hole formed in it to fit on to the barrel end
but instead of this hole being made parallel throughout it is bevelled or widened
out towards the side that is placed outwards. When the bobbin end is placed in
position on the end of the barrel a piece of soft iron or other metal wire preferably
devoid of elasticity and shaped as a ring with an open part is forced through the
small space formed around the barrel end by the bevelling of the opening in the
bobbin end until it enters the groove around the barrel end, by which means the
bobbin end is prevented from coming off. The bobbin end and the wire may be
pressed into position simultaneously by the usual machine or the wire may be
forced into position by any suitable tool.

We, FRANK LAWSON and JOHN HENDERSON, both of Jubilee Mills, Dalbeattie,
in the County of Kirkcudbright, Bobbin Makers, do hereby declare the nature
of our invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement in writing
reference being made to the accompanying sheet of drawings:-
This invention has reference to and comprises improvements in bobbins of the
class formed of a barrel or body part having either one or two disc ends secured

page_text: on same, and usually employed for holding threads or yarn and has for its object
the securing of the end or ends so that any tendency to come off is obviated.
And in order that our said invention may be properly understood we have here-
unto appended one sheet of explanatory drawings in which Figure 1 is the barrel
part of a bobbin, Figure 2 a side view and Figure 3 a plan respectively of a disc
end, Figure 4 is the securing wire, and Figure 5 is a complete bobbin partly in
section to show the method of securing on the end disc.
Referring to these drawings:-
-
In carrying into practice the improvements of this invention the barrel part A
is made much as usual, having its extremities turned to a smaller diameter so
as to form a shoulder on which smaller part the bobbin end is secured. A small
groove A however is formed around each barrel close to each extremity.
Each bobbin end B has the usual hole formed in it to fit on to the barrel end
but instead of this hole being made parallel throughout it is bevelled or widened
out as shown towards the side that is placed outwards. When the bobbin end B is
placed in position on the end of the barrel A a piece of soft iron or other metal wire C
preferably devoid of elasticity and shaped as a ring with an open part is forced
through the small space formed around the barrel end by the bevelling of the
opening in the bobbin end until it enters the groove around the barrel end by
which means the bobbin end is prevented from coming off. The bobbin end B
and the wire C may be pressed into position simultaneously by the usual machine
or the wire may be forced into position by any suitable tool.
'
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
First. The method of securing disc ends on bobbins all substantially as herein
described and illustrated by the accompanying drawings.
Second. The securing of disc ends on bobbin barrels by means of a divided wire
ring pressed into position between the disc end and barrel all substantially as
herein described and illustrated by the accompanying drawings.
