PROVISIONAL SPECIFICATION.
Improvements in Spools for Use on Sewing Machines, and for other
purposes.
I, FREDERICK WILLIAM FARR, of 434 Hackney Road, London, in the County
of Middlesex, Boot and Shoe Manufacturer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to spools for use principally on sewing machines, but they
may also be used for other purposes.
Spools to which this invention refers have been principally used for sewing
machines on which a thread that has been previously waxed is wound.
Hitherto these spools have been made chiefly of tin with the barrel and flanges
soldered together. These spools are very liable, owing to the wear and tear
to which they are subjected, to become damaged or bulged at the rim of the
flanges, and however slightly damaged the flange may be it causes the thread to be
unevenly wound, and when sewing produces a jerk which usually breaks the
thread.
Now the object of this invention is to construct a composite spool, that is, made
up of separate parts, of the same or different materials so that whenever one of such
parts become worn or damaged it may easily and readily be replaced with a new
one at a small cost.
According to this invention the spool is made of any suitable material, such as
wood, metal, tin, papier maché, or the like; or of two or more of such materials
combined and the portion on which the thread is wound (hereafter termed the
barrel) and the flanges are made in separate pieces capable of being screwed
or otherwise attached and screwed together. The barrel may be made either
straight or curved, that is, in a longitudinal direction, and a screw thread may be
cut or otherwise formed on each of its ends, for receiving and attaching the flanges
to the barrel. A screw thread or threads may also be cut or otherwise formed if
desired in other portions of the barrel, or each end of the barrel may be reduced in
diameter to form a shoulder for receiving the flange which is secured thereon by a
screw, pin, or its equivalent.
The barrel may be lined with a metallic tube which runs through its centre, and
which may be secured therein either by suitable washers screwed or otherwise
attached to the metal tube, or by any other suitable method, such as driving the
metallic lining tightly into the barrel. When washers are employed one or both of
the washers may, or may not, he let into the end or ends of the barrel, and upon
which the tension spring and washers may work.
The flanges are preferably secured to the barrel by screwing, but any other
suitable method of attaching and securing them in position may be employed.
When the flanges are screwed into the ends of the barrel, each flange may, if
desired, be retained or fixed thereon by means of a second screw, or a key, pin,
wedge, or its equivalent, to prevent them working loose.
The above described spool may be made in various sizes and employed for
receiving other threads or yarns than those that have been coated with wax or a
wax solution.
Dated the Seventh day of February 1894.

purposes.
I, FREDERICK WILLIAM FARR, formerly of 434 Hackney Road, London, but
now of 16 Mentmore Terrace, London Fields, London, in the County of Middlesex,
Boot and Shoe 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 :-
This invention relates to spools for use principally on sewing machines, but they
may also be used for other purposes.
Spools to which this invention refers have been principally used for sewing
machines on which a thread that has been previously waxed is wound.
Hitherto these spools have been made chiefly of tin with the barrel and 'flanges
soldered together. These spools are very liable, owing to the wear and tear
to which they are subjected, to become damaged or bulged at the rim of the flanges,
and however slightly damaged the flange may be it causes the thread to be unevenly
wound, and when sewing produces a jerk which usually breaks the thread.
Now the object of this invention is to construct a composite spool, that is, made
up of separate parts of the same or different materials so that whenever one of such
parts become worn or damaged it may easily and readily be replaced with a new
one at a small cost.
In the drawings I have shown several methods of carrying this invention into
practice, but I wish it to be distinctly understood that they are to be regarded as
examples only, as other ways could be adopted without departing from the nature
and principle of the said invention.
Figs. 1 and 2 are respectively a sectional elevation and a plan looking at
the top of a composite spool with the flanges screwed on and secured by a metal
bushing or tube.
Fig. 14 is a sectional elevation of composite spool with flanges screwed onto the
end of barrel.
Fig. a sectional elevation of composite spool without metal bushing or tube.
Fig. 4 a sectional elevation of composite spool with flanges placed on the
unscrewed end of the barrel and secured by metal bushing or tube.
Figs. 5 and 6 are respectively a sectional elevation and a plan looking at the top
of a composite spool having its flanges fixed to the barrel by projections and
a screw, pin, wedge, or its equivalent.
Figs. 7 and 8 are respectively a sectional elevation and a plan looking at
the top of a composite spool with say metal flanges held together by a tube
or bushing.
Fig. 9 a detail of barrel shown at Fig. 1.
Figs. 10, 11, 12, and 13 are respectively sectional elevations and plans looking at
the top of the flanges and barrel shown at Fig. 5.
Fig. 14 a detail of barrel shown at Fig. 7.
Like parts in all the views are marked with similar letters of reference.
A is the barrel on which the thread is wound and it may be made of wood, cork,
sheet tin or brass or other suitable metal, papier maché, wood pulp, or it or their
equivalents, or combination of two or more such materials; and its periphery may
be parallel as at Fig. 1, or curved longitudinally as shown by dotted lines a
at Fig. 14. A screw thread or threads may be cut upon its periphery at each end
thereof as at Fig. 1A. Or its ends may or may not be reduced as shown at Figs. 9
and 14. When reduced to form shoulders for the hereinafter described flanges B B,
the said ends may be screwed as at Figs. 1 and 9, or may be plain as at Fig. 4, or

page_text: the reduced part may be armed with one or more projections a' as at Figs. 5, 6
and 12. A recess a* may or may not be formed in one end of the barrel as
shown.
BB are the flanges which may be made of any of the hereinbefore mentioned
materials or combinations of them, but when made say of metal they may be cast,
stamped, spun, or otherwise formed into shape, and when desired strengthened by
any desired concentric, radiating, or other rims, projections, or ribs.
The said flanges are made either plain as at Figs. 1 and 4, or armed with a boss b
cast or formed on or attached thereto or provided with a facing as at Fig. 7.
When a boss b is provided the recess a* may, if desired be formed in it and the
boss may be arranged to be screwed or say soldered to the flange and to be simply
placed within or screwed to the end of the barrel A. Or if desired the flanges B B
may be provided with a recess or recesses * corresponding in number with
projections a' on the reduced end of barrel A-and arranged to communicate with
the central hole in each flange. The projections a' are made to pass through the
recess or recesses and on slightly turning the flange B the lip 3 will pass under
the projection or projections a' for connecting it to the barrel.
C is a wedge, screw, pin, key, or its equivalent (all of which are hereinafter
termed a key C) which may be used for securing the flanges in position on
the barrel, either in addition to the washer or washers D', or when such washers
are not employed, or its use may if desired be dispensed with altogether.
D is a metallic tube or bushing, hereafter termed bushing, which acts as a lining
for the barrel A. It is arranged to run through the centre of the barrel and may
be secured therein either by a suitable washer or washers D' screwed or otherwise
attached to the bushing D or by any other suitable method such as driving the
metallic lining tightly into the barrel. When washers D' are employed one or both
of the washers may or may not be let into the end or ends of the barrel; and upon
which the tension spring and washers may work. At Fig. 1 the bushing D. is
shown armed with a head d but when preferred the head d may be dispensed with
and the bushing fixed in position by a washer at each end, or the bushing may be
screwed at each end arranged so that one of its ends screws into the boss b formed
on one of the flanges B as at Fig. 7 whilst the other end of the bushing screws into
the opposite flange, or both its ends may be screwed directly to the flanges, or the
bushing may be driven tightly into the barrel A or into a solid spool or the bushing
if desired may be dispensed with altogether.
In the drawings I have shown various methods for fixing the flanges to the
barrel, as for instance :-
'
:
At Figs. 1 and 2 the spool is composed say for example of wood and its
flanges B B are screwed onto the reduced ends of the barrel A. The barrel A is
lined with a bushing D provided with an enlarged head d which is let into the
recess u* provided in one end of the barrel as shown, and the opposite end of the
bushing is secured in position by the washer D'. In this case the use of a key C is
optional.
But at Fig. 1 the flanges B B are shown screwed on to the periphery of the
barrel A and each of the said flanges is fixed or retained in position by a
key C.
At Fig. 3 the flanges are shown screwed to the reduced ends of the barrel A in
which the bushing D is dispensed with, and the use of a key C is optional.
At Fig. 4 the flanges B B are shown pressed on to the reduced plain (unscrewed)
ends of the barrel A and fixed in position by glue, cement or its equivalent.
At Fig. 5 the reduced ends of the barrel are shown armed with projections a¹
arranged to pass through the recesses * in the flanges B B, and by slightly turning
the latter, the projections a' engage with the lips 3 of the flanges. A key or
keys C may be employed for retaining the flanges in position upon the barrel when
a bushing D and washer or washers D' is or are not employed.
At Fig. 7 a barrel A with one or both ends recessed, and made say of wood is
armed with metal flanges B B, one of which is provided with a boss b and the

page_text: opposite one with a facing or facings b'. In this case the spool is held together by
screwing the ends of the bushing D respectively into the boss b and one of the
flanges B.
It will be readily understood that the parts of the herein described composite
spool may be made of the same or different materials and the flanges fixed to the
barrel by the same or any of the herein described methods as for example the
barrel A might be formed say of wood with one end reduced, and the other with a
screw thread cut on its periphery, whilst one flange might be made say of
papier maché to be say glued to the barrel whilst the other flange might be made
Bay of metal and to screw thereon.
The above described spool may be made in various sizes and employed for
receiving other threads or yarns than those that have been coated with wax or a
wax solution.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In spools such as described a parallel or curved barrel in combination with
flanges made separately and of the same or different materials and fixed to the
barrel substantially as and for the purposes described and illustrated in the
accompanying drawings.
2. In spools such as described the combination of a barrel such as A. with the
flanges such as B B secured to the said barrel by a bushing such as D with
or without the use of washers such as D¹ substantially as and for the purposes
described and illustrated in the accompanying drawings.
3. In spools such as described the combination of a barrel A with or without a
bushing D, and the flanges B B screwed or otherwise fixed to said barrel and
secured thereto by glue or by a key C substantially as and for the purposes
described and illustrated in the accompanying drawings.
