Preparing Cotton and other Fibrous Materials.
I, GEORGE PALEY, of Bank Top Mills, Preston, in the County of Lancaster,
Cotton Spinner and Manufacturer, do hereby declare the nature of this invention.
to be as follows:-
According to this invention the tubular body part of bobbins used in machines
for preparing cotton and other fibrous materials is formed of corrugated sheet metal.
(preferably thin sheet steel tinned over). The corrugations or flutings extend
nearly throughout its entire length but so as to leave a plain or non-corrugated
part at each end. In the case of bobbins for use with Mason's long collars that end
of the tube which forms the top of my improved bobbin is made to grasp or fit
tightly around a cylindrical plug having a central hole slightly larger than the
diameter of the spindle the lower part of the central hole being bell-mouthed to.
facilitate the placing of the bobbin upon the spindle. The plug is preferably made.
of wood and it may be more securely held in place by causing the end of the sheet
metal tube to slightly overlap it and to be bent over so as to press the plug down
tightly against the topmost internally projecting corrugation below. The lower
end of the corrugated tube may be soldered or brazed into a metal ferrule having
suitable notches or openings of the usual kind to engage with the washer or bobbin
wheel or the tube may be carried through the ferrule and turned back over the
lower end of the ferrule and soldered or otherwise secured thereto. In the case of
ordinary or plain bobbins the lower and upper ends are each formed in the manner:
hereinabove described with reference to the upper ends of bobbins for Mason's
long collars either one or both ends of the bobbin being slotted or notched in
the usual way and the ends of the bobbins may if desired be strengthened by
the addition of metal ferrules such as hereinabove described with reference to the
lower ends of bobbins for Mason's long collars.

Improvements in the Construction of Bobbins used in Machines for
Preparing Cotton and other Fibrous Materials.
I, GEORGE PALEY, of Bank Top Mills, Preston, in the County of Lancaster,
Cotton Spinner and Manufacturer, 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:-
According to this invention the tubular body part of bobbins used in machines for
preparing cotton and other fibrous materials is formed of corrugated sheet metal
(preferably thin sheet steel tinned over). The corrugations or flutings extend nearly
throughout its entire length but so as to leave a plain or non-corrugated part at
each end. In the case of bobbins for use with Mason's long collars that end of the
tube which forms the top of my improved bobbin is made to grasp or fit tightly

page_text: around a cylindrical plug having a central hole slightly larger than the diameter of
the spindle the lower part of the central hole being bell-mouthed to facilitate the
placing of the bobbin upon the spindle. The plug is preferably made of wood and
it may be more securely held in place by causing the end of the sheet metal tube to
slightly overlap it and to be bent over so as to press the plug down tightly against
the topmost internally projecting corrugation below. The lower end of the
corrugated tube may be soldered or brazed into a metal ferrule having suitable
notches or openings of the usual kind to engage with the washer or bobbin wheel
or the tube may be carried through the ferrule and turned back over the lower end
of the ferrule and soldered or otherwise secured thereto. In the case of ordinary or
plain bobbins the lower and upper ends are each formed in the manner hereinabove'
described with reference to the upper ends of bobbins for Mason's long collars
either one or both ends of the bobbin being slotted or notched in the usual way and
the ends of the bobbins may if desired be strengthened by the addition of metal
ferrules such as hereinabove described with reference to the lower ends of bobbins
for Mason's long collars.

Fig. 1 is a front view-one half being in elevation and the other half in section-
illustrating the general construction of my improved bobbin as hereinbefore
described with reference to Mason's long collars. a is the body or tubular part
of the bobbin having corrugations which may be either lengthwise of the tube
(as indicated by the diagrammatic section of Fig. 2) or running round the tube.
(as shewn at Fig. 1) or the tube may be corrugated in both directions the
corrugations crossing each other (as indicated by the shading lines near the upper.
left hand part of Fig. 1). b is a wood plug or upper end piece which as shewn
at Fig. 1, is made fast within the tube a between an indented shoulder c and the
inwardly projecting flange d the latter being the upper edge of the tube a spun
down on to the plug in the usual well known manner. Figs. 3 and 4 illustrate other.
methods of securing the wood plug in position. In Fig. 3 the sheet metal is pressed.
into an annular groove e and in Fig. 4 the fastening operation is effected by
indenting or pricking the sheet metal into the wood as indicated at p. At Fig. 5
is shewn a substitute for a wooden plug or upper end piece which consists of an
annular sheet metal box m soldered into its place in addition to being held between.
a shoulder c and the flange d. At Fig. 6 a similar box m is shown filled with
wood n for the purpose of imparting if required increased strength. f is the metal
ferrule forming the bottom end piece of the improved bobbin, and notches
therein of the usual kind. As before stated the ferrule f may be soldered or
brazed into the tube a. At Fig. 1 the lower edge of the sheet metal tube is shewn
a little above the bottom of the ferrule and at Fig. 7 the sheet metal is shewn
brought down completely round the bottom edge of the ferrule. Fig. 8 shews a
method of adapting a metal ferrule of the kind shewn in the preceding Figs. 1
and 7 to my improved corrugated sheet metal bobbin as made for short collars in
which is employed an inwardly projecting flange j which forms a central hole of
the same diameter as the hole in the upper end piece or plug. Although in
practice I prefer to use a metal ferrule to form the bottom of my improved bobbin
it is obvious that the required strengthening of the bottom of the bobbin may be
obtained by other methods as for example by bending over and overlapping the
edge of the sheet metal plate of which the tube is to be formed the notches
being afterwards cut out or through the overlapped or strengthened part as will be
well understood.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
"
\ 1. A bobbin having its body or tubular part composed of corrugated sheet metal

page_text: 2. In a bobbin having its body or tubular part composed of corrugated sheet
metal the combination therewith of wood or metal top and bottom end pieces
arranged substantially as hereinbefore described and shewn in the drawings.
