IMPROVED MANUFACTURE OF SPOOLS, AND APPLICATION THEREOF TO SEWING MACHINE PURPOSES
Year: 1879

page_text: LETTERS PATENT to Walter Conway Joyce, of Ruthin, in the County of
Denbigh, North Wales, for the Invention of "IMPROVED MANUFACTURE OF
SPOOLS, AND APPLICATION THEREOF TO SEWING MACHINE PURPOSES."
3 OLL A 100 dated the 17th Fehmar 1870
PROVISIONAL SPECIFICATION left by the said Walter Conway Joyce at
the Office of the Commissioners of Patents on the 17th February 1879.
WALTER CONWAY JOYCE, of Ruthin, in the County of Denbigh, North Wales.
"IMPROVED MANUFACTURE OF SPOOLS, AND APPLICATION THEREOF TO SEWING
MACHINE PURPOSES."
In shuttle and some other kinds of sewing machines an immense amount of time
is wasted by the operator in winding the spools. Without more care too than is
conveniently bestowed upon it this winding cannot be done evenly, consequently a
lesser quantity of thread than the spool could hold is wound upon it, requiring
thereby more frequent windings. Now my Invention is designed to remedy this
evil, and consists in substituting for the ordinary metallic spool one made of wood
or other cheap material machine wound. Taking the Singer machine for example,
instead of the metal spool with accurately turned pivots ordinarily used I substitute
a solid wooden spool, preferably with pivots and spool all in one piece, for as it has
only to last one usage the soft wooden pivots will not wear out till no longer
required by the thread wound on it being used up.
When the spool is empty, its cost being almost infinitessimal, it is thrown away
or into a basket to be sent back to the cotton factory, and another machine wound
spool used in its place.
In this process while saving the operator's time in winding there is actually no
extra waste beyond what there is at present, as the cotton is sent out from the
factory wound on larger and more expensive spools, and re-wound by hand, whereas
now it will be wound on smaller but cheaper spools, and all the waste of time,
soiling, and abrading of the thread, and waste of ends at present entailed are
saved.

the said Walter Conway Joyce in the Great Seal Patent Office on the 16th
August 1879.

"IMPROVED MANUFACTURE OF SPOOLS, AND APPLICATION THEREOF TO SEWING
MACHINE PURPOSES."
In shuttle and some other kinds of sewing machines an immense amount of time
is wasted by the operator in winding the spools. The thread is supplied on ordinary
spools, and has to be rewound onto the sewing machine spools, six of which are
usually supplied with each machine for the purpose. The operator usually winds
all the spools before commencing with a suitable thread for the special job in hand.
Consequently, when a change of thread is necessary what is unused on the set of
spools is almost invariably wasted, and in any case has to undergo the additional
wear, abrasion, and soiling caused by unwinding and winding again at a subsequent
time twice over; this is especially bad with silk thread, without more care too than is
conveniently bestowed upon it, this winding cannot be done evenly, consequently
a lesser quantity of thread than the spool could hold is wound upon it, requiring:
thereby more frequent windings.
Now my Invention is designed to remedy this evil, and consists in substituting
for the ordinary metallic spool one made of wood or other cheap material, machine
wound.
Taking the Singer machine for example, instead of the metal spool with
accurately turned pivots ordinarily used I substitute a solid wooden spool, pre-
ferably with pivots and spool all in one piece, for as it has only to last one usage
the soft wooden pivots will not wear out till no longer required by the thread
wound upon it being used up. When the spool is empty its cost being almost
infinitessimal it is thrown away or into a basket to be sent back to the cotton
factory, and another machine wound spool used in its place. In this process while
saving the operator's time in winding there is actually no extra waste beyond what
there is at present, as the cotton is sent out from the factory wound on larger and
more expensive spools, and rewound by hand, whereas now it will be wound on
smaller but cheaper spools, and all the waste of time, soiling, and abrading of the
thread, and waste of ends at present entailed are saved. In bobbin manufactories.
the spare wood too small for ordinary bobbins can be used for this purpose.
In the Drawings Fig. 1 shows a spool made of a single piece of wood turned
to shape; Fig. 2 is end view of same; Fig. 3, filled spool placed in shuttle ready
for use.
Having now described my Invention, and the best mode known to me of
carrying it into effect I wish it to be understood that what I believe to be new
and desire to protect under the herein before in part recited Letters Patent is,
1st. The manufacture of sewing machine spools by turning them and their
bearings out of wood, or moulding them of other similar cheap material, substan-
tially as described.
2nd. The application to sewing machines of plain wooden spools, machine
wound, and formed with wooden bearings in the cheapest manner, so that they
can be thrown away when done with.
In witness whereof, I, the said Walter Conway Joyce, have hereunto set my
hand and seal, this Fifteenth day of August, in the year of our Lord
One thousand eight hundred and seventy nine.
