Improvements in Spindles used in Braiding Machines.
I GEORGE ASHWORTп of 92 Bold Street Mose Side Manchester in the County
of Lancaster Mechanic, do hereby declare the nature of this invention to be as
follows:
This invention relates to improvements in the construction of the spindles which
are used in braiding machines, and the objects of the said invention, are first to
enable a larger bobbin to be employed, than can be used on the ordinary braiding
spindles, secondly to ensure the locking of the bobbin so as to prevent the formation
of loose ends, thirdly to diminish the noise and prevent the wear and tear of the
bobbins occasioned by their knocking against each other and fourthly to compensato
for the wear of the barrels just below the flyer..
According to the first part of my invention instead of making the flyer in the
usual form with a hole or slot at or near the middle and another at the top, I forin
the lower part which connects it with the barrel somewhat as usual and provide it
with a vertical bar (preferably of a square section) on which works a slide and this
slide carries the lower hole through which the thread passes. As the thread unwinds
from the bobbin this slide moves up and down so that the thread is always drawn.
in a straight line off the bobbin and hence a much longer bobbin than ordinary can
bo used.
At the top of the vertical bar of the flyer is fixed or formed a small bracket
through which the upper hole for the thread is made. Both these holes are
preferably fitted with bushes of glazed earthenware.
The "drop-lever" is made of a piece of wire passed through the small bracket
above named, then bent into an eye or curl and its end prolonged and bent'so as to
press against the top part of the barrel so as to prevent it from being pushed
sideways. The bobbin is locked by means of a pin driven into the top thereof
coming against the side of the "drop-lever."
The flyer is also provided just below the bobbin, and above the bead of the top
plate of the braider with a flange, rather larger than the base of the bobbin, and so
formed that as the spindles are carried round by the "roses these flanges work
together, and prevent the bobbins from striking against each other.
"
To compensate for the wear of the barrels just below the flyers 1 bend round' the
same at this point a metal tube or ferrule whilst hot, so that in cooling it shrinks
on tight, and I make the notches in the "roses" correspondingly wider. As the
tubes or ferrules become worn I remove them and shrink on frosh ones in their
place, so that the life of the machine is thereby considerably prolonged.
Dated this 25th day of August 1891.

COMPLETE SPECIFICATION.
Improvements in Spindles used in Braiding Machines.
I GEORGE ASHWORTH of 92 Bold Street Moss Side, Manchester in the County
of Lancaster, 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 construction of the spindles which are used in

page_text: '
braiding or plaiting machines and, the objects of the said invention are first to
enable a larger bobbin to be employed than can be used on the ordinary braiding
or plaiting spindles, secondly to ensure the locking of the bobbin so as to prevent
the formation of loose ends, thirdly to prevent the wear and tear of the bobbins
occasioned by the flyer knocking against the bobbins and fourthly to compensate
for the wear of the barrels just below the flyer.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the annexed sheet of drawings and the following explanation thereof.
Fig. 1 is a side elevation and Fig. 2 a vertical section of my improved braiding
spindle, Fig. 3 is a section taken horizontally through the same at about the
line A B and Fig. 4 is an elevation (partly in section) of a slight modification
thereof.
a is the hollow spindle or barrel and 6 the bobbin.
According to the first part of my invention instead of making the flyer in the
usual form with a hole or slot at or near the middle, and another at the top I form
the lower partc which connects it with the barrel a somewhat as usual and provide
it with a vertical bar d (see Figs. 1 and 2) (preferably of a square section) on which
works a slide e and in this slide is made the lower hole through which the thread
passes. As the thread unwinds from the bobbin & this slide e moves up and down so
that the thread is always drawn in' a straight line off the bobbin and hence a much
longer bobbin than ordinary can be used.
At the top of the vertical bar d of the flyer is fixed or formed a small bracket g
through which the upper hole for the thread is made. Both these holes are.
preferably fitted with bushes of glazed earthenware.
The "dropper" is made of a piece of wire passed through the small bracket.g.
above named, then bent into an eye or curl and its end prolonged and bent so as
to press against the side of the top part of the barrel a so as to prevent it from
being pushed sideways. The bobbin is locked by means of a pin i driven into the
top thereof coming against the side of the "dropper" h.
"
The flyer is also provided just below the bobbin, and above the bead of the top
plate of the braider with a flange k, rather larger than the base of the bobbin, and
so formed that as the spindles or barrels a are carried round by the "roses
these flanges & work together, and prevent the bobbins 6 from striking against each
.other.
To compensate for the wear of the barrels a just below the flyers c, I drive on
the same at this point a metal tube or ferrule tight see Fig. 4 and I make the
notches in the "roses" correspondingly wider.
As the tubes or ferrules become worn I remove them and drive on fresh. ones
in their place, so that the life of the spindles is thereby considerably prolonged.
In the modification shown at Fig. 4 I have a tube m'in place of the vertical
bard and the slide e works inside thereof. A pin n attached to the slide works
up and down through a vertical slot in the tube m and the thread passing under
this pin supports the slide e' which travels up and down as the thread is unwound'
off the bobbin b.
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 1
claim is :-
First. The combination with the flyer of a, braiding or plaiting spindle of a
vertical bar or tube outside or inside which travels a slide in which is formed the
lower hole through which thread passes together with a bracket.or projection at
the top of the said bar or tube in which is made the upper hole for the passage of
the thread.
Secondly. I claim tho "dropper" preferably formed of wire bent into an eye
or curl and its end prolonged and bent so as to press against the side of the top part

page_text: Thirdly. The peg or pegs driven into the top of the bobbin for locking the
latter by.coming against the side of the "dropper."
.
Fourthly. The combination with the flyer of the projecting flange below the
bobbin and above the bead of the top plate of the machine to prevent the bobbins
from striking against each other.
Fifthly. I claim the renewable tube or ferrule driven on the barrel just below
the flyer to compensate for the wear thereof, and
Sixthly. I claim the whole combination of braiding or plaiting spindle, and
flyer substantially as hereinbefore described and illustrated by the drawings
annexed.
