Improvements in or connected with Bobbins used in Ring Spinning
and Doubling Machinery.
We, JAMES ANDERTON SUTCLIFFE, of Globe Works, Blackburn, in the County
of Lancaster, Sheet Metal Engineer, and GEORGE PALEY, of Bank Top Mills,
Preston, in the same County, Cotton Spinner and Manufacturer, do hereby declare
the nature of this invention to be as follows;-
The object of this invention is to obviate the difficulty heretofore experienced
in connection with bobbins used in ring spinning and doubling machinery by
reason of the contraction and expansion of the upper wooden ends of such bobbins
namely that portion which fits upon and provides the required frictional grip
on the upper end or point of the spindle. Our improvements are applicable to
both sheet metal bobbins having wooden tops and also to wood bobbins with
similar tops separately introduced.
In carrying our invention into effect we employ a wooden top or plug of novel
construction. We make the extreme or uppermost end of the plug to fit the upper
portion of the outer shell of the bobbin but the lower part of the plug we make
of less diameter to allow of expansion and provide a number of vertically disposed
slits so that when the point of the spindle is inserted within the central hole of the
plug the latter is capable of not only springing out so as to accommodate itself
to varying diameters of spindle points but also allows provision for the expansion
and contraction of the wood plug owing to varying degrees of moisture and
humidity of the atmosphere.
By preference we do not bore the central hole of the plug right through but
only partially so the result being that the bobbins can only be pushed down on
the spindles to a uniform distance and cannot be jammed too tightly on the spindles.

page_text: 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:-
The object of this invention is to obviate the difficulty heretofore experienced
in connection with bobbins used in ring spinning and doubling machinery by
reason of the contraction and expansion of the upper wooden ends of such bobbins,
namely that portion of each bobbin which fits upon and provides the required
frictional grip on the upper end or point of the spindle with which it is used.
For this purpose a bobbin according to this invention is provided with a wooden
top or plug of improved construction as we shall now describe with reference to
the accompanying illustrative drawings wherein Fig. 1 shews, in vertical section,
a sheet metal bobbin with plug according to this invention applied to a spindle
which is shown in elevation; Fig. 2 is a similar view to Fig. 1, but showing the
upper end portion of the bobbin with the top or plug disengaged from the top of
the spindle; and Fig. 3 is a cross section on the line of Fig. 2, Fig. is a
similar view to Fig. 1, showing a modified construction.
The upper end 1" of the wooden top or plug 1 (hereinafter called the plug) is
made to fit the upper portion of the outer shell 2 of the bobbin in which it is
firmly secured, as for example by the upper end of the bobbin shell being turned
over so as to grip a portion of the upper end of the plug. The lower part 1b of
the plug is made of smaller diameter than the upper part and is formed with a
number of vertically arranged slits 3 that extend upward some distance so that
when the point of a spindle 4 is inserted within the central hole 5 of the plug 1,
the latter is capable of not only moving outwardly so as to accommodate itself
to varying diameters of spindle points but also allows provision for the expansion
and contraction of the wood plug owing to varying degrees of moisture and
humidity of the atmosphere.
In the example shown, the plug 1 is formed with an annular recess 1° between
its two end portions 1", 1b to facilitate the opening and closing movements of the
slit lower portion.
In Figs. 1. 2 and 3, the central hole 5 is shown as extending entirely through
the plug. It is however found preferable in practice to only bore the plug for
a portion of its length, as shown in Fig. 4, so that the bobbin can only be pushed
down on the spindle to a uniform distance and cannot be jammed thereon too
tightly.
The invention is applicable not only to sheet metal bobbins having wooden
plugs, but also to wood bobbins having similar plugs separately introduced
therein.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what I
we claim is:-
1. A bobbin for a ring spinning and doubling machine constructed with a
hollow wooden top or plug the upper end of which fits the upper portion of the
shell of the bobbin and the lower portion of which is made of less diameter than
the interior of the bobbin shell and is slit vertically, substantially as herein
described for the purposes specified.
2. A bobbin for a ring spinning and doubling machine provided with the
improved plug hereinbefore described with reference to and shown in Figs. 1, 2
and 3 of the drawing annexed, or modified according to Fig. 4.
