We BENJAMIN ALFRED DOBSON, of the firm of Dobson and Barlow, Machine
Makers, of Kay Street Works, Bolton, Lancashire, and EDWARD GILLOW, Foreman
at the same place, do hereby declare the nature of said Invention for AN
IMPROVED DEVICE FOR ASSISTING THE TRAVELLER IN SPINNING UPON THE BARE
SPINDLES OF SPINNING FRAMES, OR IN WINDING UPON DOUBLING FRAME SPINDLES,
to be as follows:-
Our invention consists in an improved device or arrangement for assisting the
traveller to revolve in spinning weft or soft yarns and we accomplish this in
the following manner:-
On the ordinary thread board we place a plate which is turned up at right angles
at the top and the bottom perpendicularly to the axis of the spindle and the top
part of the bend. Part of the plate is grooved or nicked to form the first guide
from the roller. The bottom part of the plate which is bent at right angles has an
open slot which surrounds the spindle for a portion of its circumference and may
come forward a little in advance of that portion of the circumference of the
spindle farthest from the front rollers. The spindle point is between these two
guides, namely the upper groove which acts as a thread guide and the bottom slot
which acts as a ballooning plate, and as an additional thread guide the top groove
or nick in the plate is placed a little nearer the front roller than the centre of
the spindle.

As regards the direction in which the spindles run;-If the spindle is running
"twist
way when looking at the spindle with the thread guide behind it,
the upper nick will be a little to the left of the centre of the spindle. If, on the
contrary, running "weft" way, the upper groove or nick will be a little to the
right of the centre of the spindle. The result of this arrangement is, that as
the thread is drawn round by the tension of the yarn on the traveller it rests or
passes across a certain portion of the top of the spindle until the traveller has
passed the point when a thread line from the traveller to the upper groove will
clear the spindle, then the thread will free itself from the spindle and the necessary
.

page_text: winding on will take place. As the traveller continues its revolution the thread
is gradually drawn across the spindle and the motion of the traveller is assisted
thereby and the tension on the thread reduced.
We are aware that an arrangement for assisting the motion of the thread by
discs, corrugated or otherwise, on the top of the spindle is not new and we do not
intend to claim any novelty of principle, but our idea is, to as simply as possible
imitate the action of the thread in passing over the point of a mule spindle as
applied to the ring frame, and our Invention is principally useful for fine or soft
yarns as we have before stated, but we do not tie ourselves to this special arrange-
ment nor to any particular distance from the top groove to the bottom slot or
ballooning motion and these too, may be separate and either taken back by a
motion or taken away from the spindle to allow doffing in any convenient manner.
The top and bottom guides may also be separate.

We BENJAMIN ALFRED DOBSON, of the firm of Dobson and Barlow, Machine
Makers, of Kay Street Works, Bolton, Lancashire, and EDWARD GILLOW, Foreman,
at the same place, do hereby declare the nature of said Invention for AN IMPROVED
DEVICE FOR ASSISTING THE TRAVELLER IN SPINNING UPON THE BARE SPINDLES OF:
SPINNING FRAMES OR IN WINDING UPON DOUBLING FRAME SPINDLES, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
Our invention consists in an improved device or arrangement for assisting the
traveller to revolve in spinning weft or soft yarns and we accomplish this in the
following manner :-
On the ordinary thread board we place a plate which is turned up at right
angles at the top and the bottom perpendicularly to the axis of the spindle and the
top part of the bend. Part of the plate is grooved or nicked to form the first
guide from the roller. The bottom part of the plate which is bent at right angles
has an open slot which surrounds the spindle for a portion of its circumference,
and may come forward a little in advance of that portion of the circumference of
the spindle farthest from the front rollers. The spindle point is between these two
guides, namely, the upper groove which acts as a thread guide and the bottom slot
which acts as a ballooning plate and as an additional thread guide the top groove
or nick in the plate is placed a little nearer the front roller than the centre of the
spindle. As regards the direction in which the spindles run,-If the spindle is
running "twist" way when looking at the spindle with the thread guide behind
it, the upper nick will be a little to the left of the centre of the spindle. If, on the
contrary running "weft" way the upper groove or nick will be a little to the
right of the centre of the spindle.
And in order that our Invention may be fully understood and readily carried
into effect we will describe the accompanying Sheet of Drawings, reference being
had to the figures and letters marked thereon.
Figure 1 is a side elevation of part of a spinning frame to which our improved
device for assisting the traveller is applied and Fig. 2 is a plan of the said device
and part of the thread board.

The upper plate g is nicked at g' to form the first guide from the rollers a for the

between the two plates g and h so that the nick g¹ in the upper plate acts as a
thread guide and the open slot h¹ as a ballooning plate.
drawn round by the
The result of this arrangement is, that as the thread
tension of the yarn on the traveller e it rests or passes across a certain portion of
the top of the spindle b until the traveller e has passed the point when a thread
line from the traveller to the upper groove g¹ will clear the spindle b, then the
thread will free itself from the spindle and the necessary winding on will take
place. As the traveller e continues its revolution the thread is gradually drawn
across the spindle and the motion of the traveller is assisted thereby and the
tension on the thread reduced.
We are aware that an arrangement for assisting the motion of the thread by
discs, corrugated or otherwise on the top of the spindle is not new and we do not
intend to claim any novelty of principle, but our idea is to as simply as possible
imitate the action of the thread in passing over the point of a mule spindle and
to apply the same to the ring frame.
Our invention is principally useful for fine or soft yarns as we have before
stated but we do not tie ourselves to this special arrangement nor to any
particular distance from the top groove g¹ to the bottom slot h¹, and the plates g
and h may be either taken back by a motion or moved away from the spindle to
allow doffing in any convenient manner as for instance by hinging the thread
board to the rail f¹;
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. The improved device for assisting the traveller in spinning upon the bare
spindles of spinning frames or in winding upon doubling frame spindles, said
device consisting of an adjustable nicked plate or thread guide combined with a
slotted plate or ballooning motion, substantially in the manner and for the
purposes herein described and as illustrated by the Drawings annexed.
2. In a ring spinning or doubling frame the combination with the spindle b, the
point of which lies between the two plates g and h of the adjustable thread guide
or nicked plate g and the ballooning motion or open slotted plate h, substantially
as and for the purposes herein set forth.
3. The combination with the plates g and h of means whereby the said plates
can be turned up or moved away from the spindles when doffing.
