Improvements in Rotary Shuttles of Sewing Machines and
Appliances Connected therewith.
I WILLIAM HENRY BEAL of No. 11 Gibbet Street, Halifax, in tho County of York,
Sowing machine dealer, and Mechanic, do hereby declare the nature of this invention
to be as follows :-
This invention relates to the class of shuttles for machines for purpose aforesaid
known as "Rotary" shuttles, and appliances connected therewith, and the object is
the construction of such shuttles so as to rotate in suspension, and afford facilities for
the use of one, or several shuttles in comparatively little space also to admit of
application of a large "cop," or supply of thread-so as to avoid the necessity and
loss of time consequent on frequent winding, or filling-and to improved apparatus
for taking up the slack thread of the shuttle.
In the construction of apparatus for purpose aforesaid I employ a circular spool, or
thread container, around which are teeth enclosed by side discs, or annular rings, the
teeth and edges of the discs have one or more recesses cut or formed therein so as to
form a passage way for the loop of the needle thread, and forming the hook for carrying
the loop forwards. The teeth of the circular spool gear with teeth of two corresponding
wheels the teeth, and rims of which enter between the flanges of the spool wheel which
is thus suspended, and is free to rotate without axis, or stud, or outside casing. These
wheels have spaces formed for passage of the hook, or loop carrier of the central, or
spool wheel which is driven, the said wheels receiving their motion from the main
shaft or other convenient going part of the machine.
As stated the hook or loop carrier may be formed on opposite sides of the discs so
that there will be two hooks, one carrying the loop round, whilst the other is delivering,
and the slack of the loop is being taken up the needle being timed to make the necessary
stitches.
The shuttles may be made very flat and narrow so as to admit of several being
employed in comparatively small space.
When the shuttle is required to carry a large supply, or "cop" of thread-the
shuttle is composed of a hollow circular tube within which the cop is received. The ends
of the tube are shaped so as to nearly complete the circle and form a hook or nose. for
entering the loop, and an exit or, passage way for the loop.

page_text: The loop of the thread being only equal to the section of the tube, while the diameter
of the circle may be extended to larger size. In this form of shuttle I employ in lieu
of the two wheels, three angular spaced V recessed supporting pulleys in which the
shuttle is suspended and free to revolve.
The outer rim, or periphery of the shuttle may be toothed, or have boles, so as to
be driven positively by cogs in one of the supporting pullies or by pins thereon which
enter the holes in the shuttle.
The tubular shuttle may be caused to make two revolutions to one stitch or stroke
of the needle, for purpose of admitting of the slack thread being taken up in the usual
way from the top of the work-the feed motion being timed to that of the shuttles
motion.
The slack of the shuttle thread is taken up by a pulley in which is contained a coil
spring the spring being coiled through the variation in the tension on the thread.
The under thread is by a catch or similar contrivance thrown to opposite sides of
the shuttle at alternate stitches so as to avoid tendancy to twist or snarl in the
thread.

I WILLIAM HENRY BEAL of No. 11 Gibbet Street, Halifax in the County of York,
Sewing Machine Dealer, and Mechanic, 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 the class of shuttles for machines for purpose aforesaid
known as "Rotary" shuttles, and appliances connected therewith, and the object is the
construction of such shuttles so as to rotate in suspension, and afford facilities for the
use of one, or several shuttles in comparatively little space, also to admit of application
of a large "cop" or supply of thread, so as to avoid the necessity and loss of time
consequent on frequent winding, or filling, and to improved apparatus for taking up the
slack thread of the shuttle.
In the construction of apparatus for purpose aforesaid I employ a circular spool, or
thread container, around which are teeth enclosed by side discs, or annular rings, the
teeth and edges of the discs have one or more recesses cut or formed therein so as to
form a passage way for the loop of the needle thread and forming the hook for carrying
the loop forwards. The teeth of the circular spool gear with two corresponding wheels
the teeth and rims of which enter between the discs of the spool wheel which is thus
suspended, and is free to rotate without axis, or stud, or outside casing. These wheels
have spaces formed for the passage of the hook or loop carrier of the central or spool
wheel which is driven, the wheels receiving their motion from the main shaft or other
convenient going part of the machine.
Thero may be a hook or loop carrier formed on opposite sides of the spool wheel so
that there will be two hooks, one carrying the loop round whilst the other is delivering,
and the slack of the loop is being taken up, the needle being timed to make the necessary
stitches.
The shuttles may be made very flat and narrow so as to admit of several being
employed in comparatively small space.
When the shuttle is required to carry a large supply or "cop" of thread the shuttle
is composed of a hollow circular tube within which the cop is received. The ends of
the tube are shaped so as to nearly complete the circle and form a hook or nose for
entering the loop, and an exit or passage way for the loop.
The loop of the thread is only required to be equal to the section of the tube, while
the diameter of the circle may be extended to larger size.
The outer rim, or periphery of the shuttle is provided with holes so as to be
driven positively by pins in the supporting pulley which enter the holes in the
shuttle.
The tubular shuttle may be caused to make two revolutions to one stitch or stroke
of the needle, for purpose of admitting the slack thread being taken up in the
usual way from the top of the work, the feed motion being timed to that of the shuttles
motion.
The slack of the shuttle thread is taken up by a pulley in which is contained a coiled
spring, the spring being coiled through the variation in the tension on the threads.
The under thread is by a catch or similar contrivance thrown to opposite sides of
the shuttle at alternate stitches so as to avoid tendency to twist or snarl in the
thread.

Figs. 16 and 17 are detached enlarged views or details.
In the construction of apparatus for purpose aforesaid I employ a circular spool, or
thread container 1 on pin 1ª, around the spool are teeth 2 (see fig. 1b) enclosed by side a
discs, or annular rings 3-4, the teeth and edges of the discs 3-4 have one or more
recesses 5-6 cut or formed therein so as to form a passage way for the loop 7 of the
needle thread and forming the hook 9 for carrying the loop forwards. The teeth 2 of
the circular spool gear with two or more corresponding wheels 10-11 the teeth and
rims of which enter between the discs 3 and 4 of the spool wheel 1 which is thus a
suspended, and is free to rotate without axis, or stud, or outside casing. These
wheels 10-11 have spaces 12 formed for the passage of the hook or loop carrier 9
of the central or spool wheel 1 which is driven, the wheels 10-11 receiving their
motion from the main shaft 13 or other convenient going part of the machine.
There may be a hook or loop carrier 9 formed on opposite sides of the spool wheel 14
so that there will be two hooks 9, one carrying the loop 7 round whilst the other
hook 9 is delivering, and the slack of the loop is being taken up, the needle being
timed to make the necessary stitches.
The shuttles may be made very flat and narrow so as to admit of several being
employed in comparatively small space as illustrated by fig. 2.
When the shuttle is required to carry a large supply or "cop" of thread the
shuttle is composed of a hollow circular tube 14 (see figs. 4 & 5) within which the cop
or reel is received. The ends of the tube are shaped so as to nearly complete the
circle and form a hook or nose 15 for entering the loop, and an exit or passage way
for the loop.
The loop of the thread is only required to be equal to the section of the tubo of
the shuttle 14, while the diameter of the circle of the shuttle 14 may be extended to
larger size.
The outer rim, or periphery 16 of the shuttle is provided with holes 17 so as to be
driven positively by pins 18 in the supporting pulley 19 which enter the holes 17 in 5
the shuttle. The pins 18 (fig. 4) are caused to slide and protrude into the holes 17 of
the shuttle 14 by means of the cam 17" acting on the runners 18ª of the said

page_text: pins 18, the latter and runners being withdrawn by the recess part of the cam at 18bb
so as to pass clear of the loop, whilst in figs. 6 and 7 the pins 18 are pivoted on
studs 18 and reciprocated by the cams 18° acting on the runners 18ª.
The shuttle
The cam 18 is forced by the hand lever 19b pin 19¹ and cam race 198 against the
set screws 19ª for holding the shuttle in position, reverse motion of 19° will move
back the cam and release the shuttle which can then be removed.
thus rotates in suspension without axis of its own.
The tubular shuttle 14 may be caused to make two revolutions to one stitch or stroke
of the needle, for the purpose of providing continuous motion whilst the slack thread
is being taken up in the usual way from the top of the work, the feed motion being
timed accordingly.
For carrying large supply of thread the hollow ring revolving tubular shuttle 14
carries within it the reels 28 on which a continuous thread is wound, the several reels
are mounted on stationary axis 29 the flange of the reels having teeth 30 which gear
with teeth on the adjoining flanges so as to impart simultaneous rotation by the tension
on the thread for the delivery thereof. The ends 31 of the axis 29 are attached to the
solid ends of the shuttle by set screws 32, the tube being of C section (see 13") so
that the reels and their carrying axis can be readily inserted.
The slack of the shuttle thread 20 is taken up by a pulley 21 in which is contained.
a coiled spring 22 the spring being coiled through the variation in the tension on the
threads so as to keep the thread tight, as shewn in the drawings, the hole 23 by which
the thread leaves the shuttle, being in such position as that the thread will pass the
front side of the shuttle during the revolution when the needle is up or out of the
work, and when the needle is down taking the loop the latter carries the thread. with
it to the opposite side (see figs. 8, 9 & 10). Or the under thread 20 is shifted to
opposite side by catch 23ª on axis 24 connected by rod 25 to the cam lever 26 the end
of latter being by the double cam race 27 caused to reciprocate, giving motion to the
end of the catch 23 for the purpose of transferring the thread from side to side of
the shuttle at alternate revolutions so as to avoid tendency to twist or snarl in the
thread.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is
1. The improved construction of rotary shuttles comprising a spool within a toothed
wheel and in combination with outer suspending and driving wheels as described.
2. The hollow revolving shuttle carrying the supply of thread with it, in com-
bination with a device such as herein described for transferring the thread from side
to side of the shuttle, for purpose set forth.
3. The combination of a rotary shuttle and a pulley, the pulley supporting and
rotating the shuttle by means of sliding or pivotted pins engaging with holes in the
shuttle as herein described and illustrated by annexed drawings.
4. A hollow revolving tubular open ring shuttle in combination with the series of
reels or with cop of thread therein contained as illustrated by fig. 13 and herein fully
described.
