As is well known, the cops are wound on to the spindles

Another object of the present invention is to provide
a releasable lock means of the above type which can
be used either with that type of spindle assembly where
the spindle rests on a springy support while supported
for rotary movement or where the spindle is supported
for rotary movement by a rigid bearing.
An additional object of the present invention is to
provide a releasable lock structure of the above type
which will automatically become operative when a spindle
together with the spinning bell ?xed thereto is mounted
on the bearing.
It is furthermore an object of the present invention
to provide a releasable lock device which will form part
of the whorl of the spinning bell and which will as a
result simplify the manufacture of the spinning bell.
Also, the objects of the present invention include the
provision of a releasable lock structure which is simple
