We, WILLIAM BARBOUR & SONS, Limited, of Hilden, Lisburn, in the
County of Antrim, Thread Manufacturers, do hereby declare the nature of this
invention to be as follows:-
When thread is rapidly drawn off a reel free to rotate, as for instance from reels
such as are used in boot sewing machines, and the thread is suddenly released, the
reel continues to rotate for a short time and a further quantity of thread is
unwound which is liable to become entangled, and interfere with the subsequent
drawing off of a further quantity of thread.
Now this invention has for object to prevent the rotation of the reel and
consequent withdrawal of thread therefrom when the pull on the thread is removed.
For this purpose there is used in conjunction with the reel carrier, a brake that is
held out of engagement with the reel carrier whilst thread is being drawn off the
reel but automatically comes into action to stop the rotation of the reel and reel
carrier immediately the pull on the thread ceases as I will now proceed to explain
by aid of the accompanying drawings in which
Figs. 1 and 2 are elevations at right angles to each other and
Fig. 3 a plan of a reel carrier and reel provided with brake apparatus according
to this invention.
1 is a reel carrier mounted to rotate upon a fixed pin 2 carried by a supprt 3*
that is fixed to any convenient part of the sewing or other machine to which
the apparatus is to be applied. Upon the reel carrier, which is in the form of a
tube formed at one end with a flange 1", is a reel or tube 3 that is made to fit the
carrier so as to rotate therewith and upon which thread 4 is wound. 5 is an eye
or thimble through which the thread is drawn from the reel; it is carried by a
support 6 which is fixed at one end to the pin 2. Upon this support, which in the
example shewn is formed of wire bent to hold the eye 5, is pivoted a brake con-
sisting of a tubular part 7 one end of which carries an extension 8 adapted, when
in the position shewn in dotted lines, to bear against the periphery of the flange 1*
of the reel carrier which may advantageously be surrounded by an india rubber
ring 1. At the other end of the tubular part 7 is an extension 9 which in the
example shewn, is formed of a piece of wire bent upon itself so as to form a loop
through which the thread passes on its way to the eye 5.
With the arrangement described, whilst thread is being drawn through the eye 5
from the reel or tube 3, the loop or extension 9 will be raised by the pull of the
thread into the position shewn in full lines, and the brake or extension 8 will be
held clear of the flange 1 of the reel carrier, thereby permitting the reel carrier
and reel to freely rotate. When however the thread ceases to be pulled, the
extension 9 will immediately fall by gravity into the position indicated in dotted
lines and move the brake or extension 8 into contact with the periphery of the
flange 1* thereby automatically arresting the motion of the reel carrier and the reel
thereon, and consequently the further withdrawal of thread until the same is again
pulled through the thimble 5 by the action of the machine to which the apparatus
is applied, when the loop or extension 9 will be again moved into the position
shewn in full lines and the brake removed from the flange of the reel carrier.
As
will be obvious the thread 4 may if desired be wound upon a reel formed with a
flange against the periphery of which the brake or extension 8 would act. In
this case the reel carrier 1 could be dispensed with. It is however preferred to use

page_text: the arrangement described and shewn because each reel 3 may then simply consist
of a paper tube adapted to tightly fit the rotary reel carrier.
A spring may in some cases be employed to assist the action of gravity to apply
the brake when the pull on the thread ceases.
To prevent recoil of the reel carrier, in the opposite direction, when the brake is
applied, a spring detent 10 may be provided arranged to bear against the periphery
of the flange 1 but so as to permit of free rotation of the reel carrier when the
thread is pulled through the eye 5.

COMPLETE SPECIFICATION.
Combined Reel Carrier and Brake.
A communication from abroad by THE BARBOUR FLAX SPINNING COMPANY,
of Paterson, New Jersey, United States of America, Thread Manufactuters.
We, WILLIAM BARBOUR & SONS, Limited, of Hilden, Lisburn, in the
County of Antrim, Thread Manufacturers, 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:-
When thread is rapidly drawn off a reel free to rotate, as for instance from reels
such as are used in boot sewing machines, and the thread is suddenly released,
the reel continues to rotate for a short time and a further quantity of thread is
unwound which is liable to become entangled, and interfere with the subsequent
drawing off of a further quantity of thread.
Now this invention has for object to prevent the rotation of the reel and
consequent withdrawal of thread therefrom when the pull on the thread is removed.
For this purpose there is used in conjunction with the reel carrier, a brake that is
held out of engagement with the reel carrier whilst thread is being drawn off the
reel, but automatically comes into action to stop the rotation of the reel and reel
carrier immediately the pull on the thread ceases as we will now proceed to explain
by aid of the drawings filed with our Provisional Specification in which
Figs. 1 and 2 are elevations at right angles to each other and
Fig. 3 a plan of a reel carrier and reel provided with brake apparatus according
to this invention.
1 is a reel carrier mounted to rotate upon a fixed pin 2 carried by a support 3*
that is fixed to any convenient part of the sewing or other machine to which the
apparatus is to be applied. Upon the reel carrier, which is in the form of a tube
formed at one end with a flange 1º, is a reel or tube 3 that is made to fit the carrier
so as to rotate therewith and upon which thread 4 is wound. 5 is an eye or
thimble through which the thread is drawn from the reel; it is carried by a
support 6 which is fixed at one end to the pin 2. Upon this support which in the
example shewn is formed of wire bent to hold the eye 5, is pivotted a brake
consisting of a tubular part 7 one end of which carries an extension 8 adapted,
when in the position shewn in dotted lines, to bear against the periphery of the
flange 1 of the reel carrier which may advantageously be surrounded by an india
rubber ring 1b. At the other end of the tubular part 7 is an extension 9 which in
the example shewn, is formed of a piece of wire bent upon itself so as to form a
loop through which the thread passes on its way to the eye 5.
With the arrangement described, whilst thread is being drawn through the
eye 5 from the reel or tube 3, the top or extension 9 will be raised by the pull of
the thread into the position shewn in full lines, and the brake or extension 8 will
be held clear of the flange 1ª of the reel carrier, thereby permitting the reel carrier

page_text: and reel to freely rotate. When however the thread ceases to be pulled, the
extension 9 will immediately fall by gravity into the position indicated in dotted
lines and move the brake or extension 8 into contact with the periphery of the
flange 1 thereby automatically arresting the motion of the reel carrier and the
reel thereon, and consequently the further withdrawal of thread until the same is
again pulled through the thimble 5 by the action of the machine to which the
apparatus is applied when the loop or extension 9 will be again moved into the
position shewn in full lines and the brake removed from the flange of the reel
carrier. As will be obvious the thread 4 may if desired be wound upon a reel
formed with a flange against the periphery of which the brake or extension 8 would
act. In this case the reel carrier 1 could be dispensed with. It is however
preferred to use the arrangement described and shewn because each reel 3 may
then simply consist of a paper tube adapted to tightly fit the rotary reel carrier.
A spring may in some cases be employed to assist the action of gravity to apply
the brake when the pull on the thread ceases.
To prevent recoil of the reel carrier in the opposite direction, when the brake
is applied, a spring detent 10 may be provided arranged to bear against the
periphery of the flange 1 but so as to permit of free rotation of the reel carrier
when the thread is pulled through the eye 5.
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 :-
1. A combined reel carrier or reel and brake so constructed and arranged with
relation to each other that whilst thread is being pulled from the reel the brake
will be held out of action by the thread and when the pull on the thread ceases,
the brake will be automatically brought into action to arrest the motion of the
reel and prevent further unwinding of the thread substantially as herein
described.
2. The combined reel carrier and brake constructed and operating substantially
as described and shewn, whether with or without the detent 10.
