PROVISIONAL SPECIFICATION.
Improvements connected with Sheet Metal Bobbins for Ring Spinning
and Doubling Machines.
We, GEORGE PALEY, of Bank Top Mills, Preston, in the County of Lancaster,
Cotton Spinner and Manufacturer, and JAMES ANDERTON SUTCLIFFE, of Globe
Works, Blackburn, in the same County, Sheet Metal Engineer, do hereby declare
the nature of this invention to be as follows:-
This invention relates to improvements connected with sheet metal bobbins for
ring spinning and doubling machines and has for its object improved means for
causing such bobbins to adhere to the spindles more firmly or securely than
heretofore and at the same time to be more adjustable to the varying diameters
of the spindles and to be more easily detachable therefrom.
According to one arrangement we enclose within the sheet metal body or shell
of the bobbin in suitably formed upper and lower annular recesses or grooves a flat
coiled or convolute spring which when twisted on to the spindle in one direction
tightens itself thereon and when untwisted in the other direction as readily loosens
itself. It will be obvious that the direction of the coiling of the spring must be
such that the drag of the yarn or thread as it is wound on to the bobbin during the
operation of spinning or doubling will have the tendency to twist or tighten the
bobbin upon the spindle.
According to another arrangement in lieu of flat coiled or convolute springs we
employ crinkled or wavily corrugated flat springs in the form of an annulus.
Dated this 3rd day of November 1896.
COMPLETE
CIFICATION.
Improvements connected with Sheet Metal Bobbins for Ring Spinning
and Doubling Machines.
We, GEORGE PALEY, of Bank Top Mills, Preston, in the County of Lancaster,
Cotton Spinner and Manufacturer, and JAMES ANDERTON SUTCLIFFE, of Globe
Works, Blackburn, in the same County, Sheet Metal 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:―
This invention relates to improvements connected with sheet metal bobbins for
ring spinning and doubling machines and has for its object improved means for

page_text: causing such bobbins to adhere to the spindles more firmly or securely than
heretofore and at the same time to be more adjustable to the varying diameters
of the spindles and to be more easily detachable therefrom.
According to one arrangement we enclose within the sheet metal body or shell
of the bobbin in a suitably formed annular recess or
groove a flat
coiled or convolute spring which when twisted on to the spindle in one direction
tightens itself thereon and when untwisted in the other direction as readily loosens
itself. It will be obvious that the direction of the coiling of the spring must be
such that the drag of the yarn or thread as it is wound on to the bobbin during the
operation of spinning or doubling will have the tendency to twist or tighten the
bobbin upon the spindle.
According to another arrangement in lieu of flat coiled or convolute springs we
employ crinkled or wavily corrugated flat springs in the form of an annulus.
In the accompanying drawings Fig. 1 is a side view partly in section and Fig. 2
a plan view shewing the application of a convolute spring a to a sheet metal
bobbin and Figs. 3 and 4 are corresponding side and plan views shewing the
application of a crinkled spring a¹ to a sheet metal bobbin according to our said
invention.
In the said figures b is an annular recess formed by enlarging the lower end
of the bobbin into which the springs a or a (as the case may be) are inserted and
c is a sheet metal cap or annulus which when a spring has been inserted in the
groove is soldered fast to the outside of the lower enlarged part of the bobbin.
Instead of making the crinkled spring a in the form of a regular annulus we
find it more effective if made in the form shewn at Fig. 4 and with an over-
lapping split joint a (see also Fig. 5).
In our Provisional Specification we referred to the use of springs of the kind
hereinabove described as applied both to the upper and lower ends of the bobbin.
Although they may be so used we find in practice that ordinarily the application
of only one spring namely at the lower end of the bobbin is sufficient for the
purpose required.
Having now particularly, described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is:
With sheet metal bobbins for ring spinning and doubling machines the use of
springs in manner substantially as herein described and shewn in the accompanying
drawings for the purpose specified
pated this 3rd day of August 1897.
