IMPROVE- MENTS IN FLYERS FOR SPINNING, ROVING, DOUBLING, DRAWING, AND TWISTING WOOL AND, OTHER FIBROUS SUBSTANCES to be as follows:
Year: 1884

page_text: I, THOMAS BROUGHTON, of 22, Mornington Street, Keighley, in the county of
York, Spinner, do hereby declare the nature of the said invention for "IMPROVE-
MENTS IN FLYERS FOR SPINNING, ROVING, DOUBLING, DRAWING, AND TWISTING
WOOL AND, OTHER FIBROUS SUBSTANCES to be as follows:-
"
This invention relates to improvements in flyers for spinning, roving, doubling,
drawing and twisting wool and other fibrous substances.
In carrying out my invention instead of forming the twizzle with a sharp curve
or curl at the top as has hitherto been the practice whereby the yarn was com-
pelled to run in one part only of the twizzle thereby cutting a groove in the twizzle
and producing much friction on the yarn, I form the upper part of the twizzle
or curl of the flyer on which the yarn runs straight and perfectly horizontal so that
the yarn can pass along any part of it with equal facility thus considerably
lessening the friction as the yarn has a more extended surface to work upon.
Or instead of forming the twizzles as hereinbefore described I sometimes fix
short horizontal bars at the extremity of the legs of the flyer with a pin or stop at
the end of each of such horizontal bars to prevent the yarn from running off.
By either of these means I prevent the yarn from running all in one place and
cutting a groove in the twizzle of the flyer or its equivalent and provide a straight
horizontal surface upon any part of which the yarn may work.

page_text: I, THOMAS BROUGHTON of 22 Mornington Street, Keighley, in the County of
York, Spinner, do hereby declare, the nature of my invention for "IMPROVEMENTS
IN FLYERS, FOR SPINNING, ROVING, DOUBLING,, DRAWING AND TWISTING, WOOL,
AND OTHER FIBROUS SUBSTANCES," and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
My invention relates to improvements in the form of the twizzle or curl of flyers,
the top part of which twizzle, whereon the yarn passes, being made straight and
horizontal, for the purpose of allowing the yarn to traverse a given distance,
instead of the top part of such twizzle being curved, in a similar manner to the
bottom part, as has been the practice hitherto, whereby the yarn passing through
the twizzle, is confined to, and constantly bears upon, one narrow space, in the top
curve of the twizzle, and wears a notch or groove therein.
To carry out my invention, in forming the twizzles at the extremities of the legs
of a flyer, instead of turning over the top part of such twizzle in a similar curve
to the bottom part, and thereby leaving only a small circular eye for the yarn to
pass through, I produce or continue the wire or other material of which the flyer is
formed, in a horizontal straight line, thereby leaving a level space, within which the
yarn can traverse from side to side, instead of being confined to one narrow place,
and thereby wearing a groove or notch in the upper curve of the twizzle, as has
been hitherto the case.
Instead of forming the twizzles in the manner herein before described, I sometimes
fix short horizontal bars at the lower extremity of the legs of a flyer, to answer the
same purpose as my improved form of twizzle, and projecting downwards from
the ends of these horizontal bars I fix pins or stops to prevent the yarn from
slipping off.
By either of these means I prevent the yarn from running all in one place, and
thereby cutting a notch, or groove, in the upper curve of the twizzle of a flyer
or its equivalent, and provide a straight horizontal space, within and from side to
side of which, the yarn may freely traverse.
In order to enable my invention to be fully understood I will proceed to describe
the same with reference to the accompanying drawings in which,
Figures 1 and 2 represent elevations of flyers which have their twizzles or curls
formed according to my improved method..
Figure 3 represents an elevation of the ordinary form of flyer hitherto in use.
In Figure 4 a short horizontal bar is fixed at the bottom ends of the legs of a
flyer, at each end of this horizontal bar studs or guards are fixed projecting down-
wards to prevent the yarn from slipping out.
Similar letters refer to similar parts in Figures 1, 2 and 3.
In Figures 1 and 2 the twizzle A is represented as being slightly elongated
horizontally, and having the lower part curved, but the upper part in the line B C is
perfectly straight and horizontal, and may be made of any required width in the

page_text: line B C, and upon this portion the yarn traverses freely from side to side in
passing rapidly through the twizzle, and consequently wears no notch or groove in
the upper part of the twizzle, but maintains a straight, smooth, and unbroken
surface. In Figure 3 the yarn by its friction in one place, in the upper curve of the
twizzle bas worn a notch or groove as represented at D, which notch interferes
with the free passage of the yarn, and causes undue friction.
•
In Figure 2, the end of the upper part of the twizzle G, of my improved con-
struction, is represented as being bent down to form a guard or stop to prevent the
yarn from slipping off.
In Figure 4 the legs of the flyer are represented at A, and the horizontal
bars B C, having studs or guards D E, projecting downwards to prevent the yarn
from slipping off the ends of the horizontal bars.
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 construction, in a straight horizontal line, of the upper part of the twizzles
or curls of flyers in the manner and for the purpose as set forth.
2. The construction in a straight and horizontal line of that part of the twizzles
or curl of flyers upon which the yarn passes on its way to the spool, so that the
yarn may traverse from side to side of the straight part of the twizzle, instead of
being confined to one part, as is the case in twizzles of which the upper part is
curved, as described.
3. The construction of flyers with a short horizontal bar at the bottom extremity
of the legs, and with stops or pins projecting downwards from the ends of such
horizontal bars, for the purpose and in the manner herein set forth.
