Improvements in the Construction of Bobbins used in Machines for
Winding Yarns.
A
We, GEORGE PALEY of 15 Ribblesdale Place, 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 a method of constructing or forming of sheet metal-
but preferably of thin sheet steel coated with tin-bobbins of the class known as
"winders' bobbins" used in machines for winding cotton or other yarns.
We make the barrel part of such bobbins in the shape of a sheet metal cylinder
or tube corrugated if desired having near each of its extremities an outwardly pro-
jecting bead or collar pressed out or "spun" by any of the ordinary methods.
The flanges of the bobbin are made also of sheet metal in the form of an annulus
or washer (corrugated if desired to give the flanges additional strength) the ends of
the cylinder or tube being passed through the central holes of the flanges which
rest upon the bead or collar and against which they may be secured by one or other
of the methods hereinafter described. In one arrangement we employ a smaller
inner cylinder or tube concentric with the outer cylinder the inner tube having its
internal diameter suited to its required fit on the winding machine spindle. The
inner tube is shorter than the outer one and is connected at each of its ends to the
narrow-end of a sheet metal funnel or cone-shaped mouthpiece whose wider or
outer end extends somewhat beyond the projecting extremity of the outer tube the
outer edge of the funnel being bent over so as to nip or enclose the end of the outer
tube projecting through the flange and the three thicknesses of sheet metal thus
formed are then pressed down flat upon the flange which thus becomes firmly
secured in place.
Another arrangement consists in dispensing with an inner tube and filling up
each end of the barrel part of the sheet metal bobbin with cylindrical plugs
(preferably of wood although they may be of metal) having a central hole bell-
mouthed from the inside the holes being of suitable diameter to fit the spindle and
the bell-mouths being designed to facilitate the guiding and placing of the bobbin
upon the spindle. In the case of wooden plugs they may be secured in place
either by indenting the surrounding sheet metal tube the indentations being pressed
into the wood or by means of an inwardly projecting bead which may be pressed
or spun into a corresponding groove on the periphery of the plug. In either case
the ends of the sheet metal barrel are turned over on to the flange and presse.I
down against an outwardly projecting bead. A third arrangement consists in
cutting out spaces in the ends of the barrel or cylinder so as to leave at intervals
ears or projecting parts which are passed through corresponding holes in the flange
and are rivetted down thereupon. In this case the flange has a central hole smaller
than in the other arrangements hereinabove described through which is fitted a
smaller inner cylinder or tube which fits upon the spindle and this inner tube may
be fastened to the flange by means of an internal outwardly projecting collar or
bead and the ends of the said inner tube brought down flat and soldered upon the
onter side of the flange

page_text: In the several joints or fastenings hereinabove referred to soldering may if
desired be employed to impart additional firmness or strength thereto.

DE MOITIATION.
Improvements in the Construction of Bobbins used in Machines for
Winding Yarns.
We, GEORGE PALEY, of 15, Ribblesdale Place, 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 a method of constructing or forming of sheet metal-
but preferably of thin sheet steel coated with tin-bobbins of the class known as
"winders' bobbins " used in machines for winding cotton or other yarns.
We make the barrel part of such bobbins in the shape of a sheet metal cylinder
or tube corrugated if desired having near each of its extremities an outwardly
projecting bead or collar pressed out or spun" by any of the ordinary methods.
66
The flanges of the bobbin are made also of sheet metal in the form of an annulus
or washer (corrugated if desired to give the flanges additional strength) the
ends of the cylinder or tube being passed through the central holes of the
flanges which rest upon the bead or collar and against which they may be
secured by one or other of the methods hereinafter described. In one arrange-
ment we employ a smaller inner cylinder or tube concentric with the outer
cylinder the inner tube having its internal diameter suited to its required fit
on the winding machine spindle. The inner tube is shorter than the outer
one and is connected at each of its ends to the narrow end of a sheet metal
funnel or cone-shaped mouthpiece whose wider or outer end extends somewhat
beyond the projecting extremity of the outer tube the outer edge of the funnel
being bent over so as to nip or enclose the end of the outer tube projecting through
the flange and the three thicknesses of sheet metal thus formed are then pressed
down flat upon the flange which thus becomes firmly secured in place. Another
arrangement consists in dispensing with an inner tube and filling up each end of
the barrel part of the sheet metal bobbin with cylindrical plugs (proferably of
wood although they may be of metal) having a central hole bell-mouthed from
the inside the holes being of suitable diameter to fit the spindle and the bell-mouths
being designed to facilitate the guiding and placing of the bobbin upon the spindle.
In the case of wooden plugs they may be secured in place either by indenting
the surrounding sheet metal tube the indentations being pressed into the wood or
by means of an inwardly projecting bead which may be pressed or spun into a
corresponding groove on the periphery of the plug. In either case the ends of the
sheet metal barrel are turned over on to the flange and pressed down against an
outwardly projecting bead. A third arrangement consists in cutting out spaces in
the ends of the barrel or cylinder so as to leave at intervals ears or projecting parts
which are passed through corresponding holes in the flange and are rivetted down
thereupon. In this case the flange has a central hole smaller than in the other
arrangements hereinabove described through which is fitted a smaller inner cylinder
or tube which fits upon the spindle and this inner tube may be fastened to
the flange by means of an internal outwardly projecting collar or bead and the

page_text: ends of the said inner tube brought down flat and soldered upon the outer side
of the flange. In the several joints or fastenings hereinabove referred to
soldering may if desired be employed to impart additional firmness or strength
thereto.
The accompanying drawings illustrate the method of constructing our improved
sheet metal bobbins as hereinabove described.
In the several figures a is the sheet metal barrel part of our said improved
bobbin shewn corrugated at Figs. 1, 2, 4, 5 and 6 and plain (or uncorrugated) at
Figs. 3 and 7. Fig. 1^ illustrates in cross section the form of corrugation we
preferably employ.
66
"
At Fig. 1 the two extremities of the corrugated barrel are left plain the upper
and lower edges d d of the barrel being turned or spun inwardly so as to
enclose or embrace a wooden cylindrical plug b-preferably bell-mouthed on each
side as shewn-between a shoulder c on the ends of the corrugations and the
turned-in part.
In this arrangement we form each flange of the bobbin of two
washers or annular plates of sheet metal so as to form a hollow box the inner
washere being plain and the outer one f corrugated concentrically so as to afford
additional strength and the plates e and f being soldered together and the box-like
flange being then secured to the barrel part a by the operation in the process of
soldering known as "sweating."
At Fig. 2 the corrugations in the plates ff are formed radially the flange (e ƒ )
being held in place between an outwardly projecting bead g and an outwardly
projecting lip on the end of the corrugated barrel a. The flange e f is to be
affixed in its place on the barrel a by being sweated thereon as in the previously
described arrangement.
In Figs. 1 and 2 i is a sheet metal shield or lining for protecting the wood
plugs the said shield being secured in place in the manner shewn at Figs. 1 and 2
or in any other convenient manner.
Fig. 3 is a diagrammatic sectional view in which the flange is formed of a single
sheet metal plate having radial corrugations jj which bulge or project outwardly
as shewn. In the arrangement shewn at the said Fig. 3 a is the barrel-made
plain or without corrugations-k is a smaller inner cylinder or tube made to
suitably fit the winding machine spindle a sheet metal funnel or cone-shaped
mouth-piece and g an outwardly projecting bead or collar " spun on the
barrel a the several parts referred to being secured together by overlapping
(ns shewn in Fig. 3) and after having been pressed tightly together by soldering
or sweating.
"
In practice we prefer to use radial corrugations-bulging outwardly-in the
case of single plate flanges (of the kind shewn at Fig. 3.) in preference to
concentric corrugations the annular indentations or recesses of which on the inner
sides of the flanges-might in some cases be liable to interfere with the free
unwinding or running-off of the yarn or thread from the bobbin.
Fig. 4 illustrates a method of securing the wood plug in place by means of
indentations m in the periphery of the barrel a and
Fig. 5 another method of securing the wood plug in place namely by means of
an inwardly projecting bead n which may be pressed or spun into a corresponding
groove on the periphery of the plug. In both the said arrangements the ends d d
of the barrel a are shewn turned over on to the flange so that the latter may be
pressed down against the outwardly projecting beads g g and thus secured in
position.
Fig. 6 shews another arrangement or modification for securing the wood plug
and flange in position and
Figs. 7 and 8 illustrate in elevation and plan view respectively the arrangement
hereinabove referred to in which spaces are cut out in the ends of the barrel a so
as to leave the projecting ears o o which are passed through correspondingly shaped
holes p p in the flange and are rivetted down thereon or they may also be soldered
thereto.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The improved bobbin consisting essentially of the combination with a sheet
metal barrel whether corrugated or plain of corrugated sheet metal flanges the said
parts being constructed formed and arranged substantially as hereinabove described
and shewn in the drawings.
