IMPROVEMENTS IN RING AND FLY THROSTLE FRAMES For SPINNING AND DOUBLING COTTON AND OTHER FIBROUS MATERIALS
Year: 1884

page_text: We ROBERT DAWSON, Mill Manager 123 Shaw-Side, JOSEPH COOK, Spinning
Master 72 Shaw-Side and HENRY HOPKINSON, Spinning Master 123 Shaw-Side,
all of Shaw, near Oldham in the County of Lancaster do hereby declare the nature
of said invention for "IMPROVEMENTS IN RING AND FLY THROSTLE FRAMES For
SPINNING AND DOUBLING COTTON AND OTHER FIBROUS MATERIALS;" to be as
follows:-
In Ring and Fly throstles for spinning and doubling the tin roller or rollers
which drive the spindles by bands is driven from the motor power by a belt
working upon a pulley on the shaft or axis of the tin drum, or upon one of the tin
drums where two are used, and the rollers are geared up with the tin drum thus
driven.
The amount of twist to be put into the yarn being spun, or the threads being
twisted or doubled has been hitherto regulated by change wheels, which increased
or diminished the speed of the front rollers delivering the yarn or thread, but left
the speed of the spindles unaltered.
Our invention has for its object arrangements for increasing or decreasing the
amount of twist to be put in the yarn or thread without necessarily altering the
speed of the front rollers.
In some frames two tin drums are used to drive the spindles and the driving
pulleys are on the shaft of one of the tin drums.
We disconnect one part of this shaft having the driving pulley upon it, from the
other forming the axis of the tin drums, but the two parts of the shaft where
disconnected, may come end to end and run in the same long bearing, or the
disconnected portion of the shaft may be in independent bearings.
The disconnected or independent shaft is geared up with the rollers and the ratio
of speed between the rollers and shaft need never be altered, and it is also geared
up so as to readily vary the speed by carrier and change wheels, with the other tin
drun (which is ordinarily a guiding drum for the bands driving the spindles and
is driven by the bands passing round both tin drums) so that by our improvements
the driven tin-drum (as hitherto used) becomes, or may be made the driving tin
drum and vice-versa.

page_text: When there is only one tin drum to drive the spindles, we disconnect the driving
pulley end of shaft from the tin drum shaft, or use a separate shaft in independent
bearings, and then gear this disconnected or separate shaft by carrier and change
wheels with the rollers; and tin-drum or first gear it with a short shaft in suitable
bearings, which is geared up with the tin-drum.

We ROBERT DAWSON, Mill Manager, 123 Shaw-Side, JOSEPH Cook, Spinning
Master 72 Shaw-Side and HENRY HOPKINSON, Spinning Master 123 Shaw-Side,
all of Shaw, near Oldham in the County of Lancaster do hereby declare the nature
of said invention for IMPROVEMENTS IN RING AND FLY THROSTLE FRAMES For
SPINNING AND DOUBLING COTTON AND OTHER FIBROUS MATERIALS, and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :—
In Ring and Fly throstles for spinning and doubling the tin roller or rollers,
drum or drums which drive the spindles by bands is driven from the motor power
by a belt working upon a pulley on the shaft or axis of the tin drum or upon one
of the tin drums where two are used and the front or delivery rollers are geared
up with the tin drum thus driven.
The amount of twist to be put into the yarn being spun or the threads being
twisted or doubled has been hitherto regulated by change wheels which increased
or diminished the speed of the front rollers delivering the yarn or thread, but left
the speed of the spindles unaltered.
Our invention has for its object arrangements for increasing or decreasing the
amount of twist to be put in the yarn or thread without necessarily altering the
speed of the front rollers or the speed of the first motion driving shaft.
In some frames two tin drums are used to drive the spindles, and the driving
pulleys are on the shaft of one of the tin drums; we disconnect one part of this
shaft having the driving pulley upon it from the other forming the axis of the tin
drums, but the two parts of the shaft where disconnected, may come end to end
and run in the same long-bearing or the disconnected portion of the shaft may be
in independent bearings.
The disconnected or independent shaft is geared up with the rollers and the ratio
of speed between the rollers and the driving shaft need never be altered, and it is
also geared up so as to readily vary the speed by carrier and change wheels, with
the other tin drum (which is ordinarily a guiding drum for the bands driving the
spindles and is driven by the bands passing partly round both tin drums) so that
by our improvements the driven tin drum (as hitherto used) becomes or may be
made the driving tin drum and vice-versa.
When there is only one tin drum to drive the spindles, we disconnect the driving
pulley end of shaft from the tin drum shaft, or use a separate shaft in independent
bearings, and then gear this disconnected or separate shaft by carrier and change

page_text: wheels with the rollers, and tin drum, or first gear it with a short shaft in suitable
bearings which is geared up with the tin drum.
Fig 1 is an end elevation and fig 2 a plan illustrating the mode of carrying our
invention into effect in the case of frames having only one "tin roller or drum" for
driving the spindles.
Figs 3 and
are views corresponding to figs 1 and 2 respectively illustrating
the mode of carrying out our invention when two " tin rollers" or drums are used
for driving the spindles.
In figs 1 and 2-a are the fast and loose driving pulleys on a shaft a¹ in
bearings a² and a³.
In the ordinary arrangement this shaft a is also the shaft of the tin drum b
being in the same axial line, but the shaft b₁ for the latter, according to our
invention is a separate and disconnected shaft from the shaft a¹ though having
a bearing a³ at one end common to both shafts a¹ and b'.
The train of spur wheels from the pinion on the shaft a¹ to the front roller
shaft c is the same as in the ordinary arrangement, that is, a pinion c¹ on a shaft a¹
gears with a wheel c² having its axis in a bearing in a bracket secured on an
arm swivelling and adjustable round the shaft a¹, a pinion e' on the axis of the
wheel c² gears with a carrier wheel c which gears with a wheel c on the front
roller shaft c on one side, a similar carrier c gearing with the carrier c³ drives the
front roller wheel c on the other side.
The tin drum bis driven from the shaft a¹ by a wheel b on the latter gearing
with an adjustable carrier be driving a wheel b (which may be the change wheel)
on the end of a short shaft in bearings in a bracket. The other end of this shaft
has a wheel b upon it gearing with one (66) on the tin drum shaft b¹.
In fig 1, the pitch lines only of the wheels are shown in peculiar dotted line.
With the exception that the pulley shaft a¹ is disconnected or detached from the
tin drum shaft bi and that the wheels b2 63, 64 b and be are introduced the gearing
is the ordinary arrangement where the spindles are driven from one tin drum.
If desired the shaft a¹ may be arranged on one side, then three wheels need only
be used between the shaft a¹ and the tin drum shaft b' as hereinafter described in
reference to figs 3 and 4.
J
In figs 3 and 4 the fast and loose pulleys a and their shaft a¹ are arranged as
described in reference to figs 1 and 2, the driving shaft a¹ being in the same axial
line and bearing but separate from the shaft b' of one of the tin drums b which is
driven by the spindle bands passing partly round the other tin drum bx which
latter is driven by spur wheels one (6) of which is on the shaft a¹ and gears with
a carrier 63 on a stud adjustable in a bracket and gearing with a wheel b' on the
end of the shaft 6° for the tin roller bx, which latter wheel b is or may be the
change wheel.
The front rollers c are driven by a train spur gear from the shaft a¹ as in the
ordinary arrangement-that is, a wheel c¹ on the shaft a¹ gears with one c² on a
shaft having a bearing in a bracket secured to an arm swivelling and adjustable
round the shaft a¹, and a pinion c* on the axis of the wheel c² gears with a carrier
wheel c³ on a stud and with another carrier c gearing with the wheel ce on the
front roller c, the front roller c on the opposite side being driven by a carrier
wheel c gearing with the carrier c³.
The pitch lines of the wheels referred to are only shown in fig 3 in peculiar
dotted line. With the exception that the shaft a¹ is disconnected or separate from
the shaft b' of the tin drum b and that the latter is driven by the spindle bands
from the other drum 6* which is positively driven from the shaft a¹ by the
wheels b³, b³ and 6, the gearing in the arrangement shown by figs 3 and 4 is that
in ordinary use in machines having two tin drums b and 6×.
In both modifications hereinbefore described the mechanisin may be varied in
gearing and arrangement, but that described is unobjectionable and easily applied
with the least change to frames or machines of ordinary arrangement and
construction.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed-We declare that what
we claim is
1. In ring and Fly throstle spinning and doubling frames, arranging the gearing
so that the twist may be altered without altering the speed of the front or delivery
rollers or the first motion or belt shaft, substantially as hereinbefore described.
2. In Ring and Fly Throstle spinning and doubling frames, the combinations
and arrangements of mechanism for changing or altering the twist without altering
the speed of the front roller or that of the first motion belt shaft substantially as
herein before described and illustrated by the drawings.
