We THOMAS TETLOW and JOHN THOMAS TETLOw both of High Lee Mill Lee
Street Oldham in the County of Lancaster Cotton Doublers do hereby declare the
nature of our invention for "AN IMPROVEMENT IN MACHINES CALLED TWINERS'
EMPLOYED FOR DOUBLING YARN" to be as follows:-
The object of this invention is to prevent the accumulation of dirt in the slots
or notches of the slotted guide plate through which the doubled yarn passes on its
way to the spindles, whereby a cleaner and better yarn is produced, the occurrence
of "threefold or bad knots is prevented as well as the liability to dirt and
"Blubs" in the single yarn.
The invention, consists in an improved guide and also in an improved application
of the same to the twiner whereby the cleaning of the yarn is improved and the
passage of bad ends and knots in doubling the yarn is entirely prevented.
We make the guide plate wider than heretofore and we strengthen the same
also by the addition of a bar or otherwise and we cut the notches or slots in the
same deeper than usual, and we cause the yarn to traverse constantly up and down
in the said notches or slots so as to keep them quite clear from dirt by fixing the
said guide plate in the position and in the manner following: that is to say we fix
the guide plate to the "slide" of the twiner at the back thereof (or on that side
nearest to the spindles) and we secure it thereto in such a way that there is a space
left between the guide plate and the slide for dirt and lumps to fall down through
such space.
The position of the "slide" being higher than that of the spindles it will be
evident that the angle of inclination of the thread or yarn between the "slide" and
the spindles will be varied as the "slide" traverses to and fro, and by attaching
the guide plate to the back of the slide this varying angle of inclination will cause
the yarn to rise and fall alternately in the slots or notches and thus keep them
quite clear of dirt.
By the use of this invention a finer notch or slot can be employed than heretofore
and the passage being kept quite clear and no accumulation of dirt being possible
a cleaner and better yarn will be produced.

An Improvement in Machines called "Twiners" Employed
for Doubling Yarn.
We THOMAS TETLOW and JOHN THOMAS TETLOW both of High Lee Mill, Lee
Street, Oldham, in the County of Lancaster Cotton Doublers do hereby declare the
nature of our invention for "AN IMPROVEMENT IN MACHINES CALLED 'TWINERS'
EMPLOYED FOR DOUBLING YARN" and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
The object of this invention is to prevent the accumulation of dirt in the slots
or notches of the slotted guide plate through which the doubled' yarn passes on its
way to the spindles whereby a cleaner and better yarn is produced, the occurrence
of "threefold" or bad knots is prevented as well as the liability to dirt and "slubs"
in the single yarn.
The invention consists in an improved guide and also in an improved application
of the same to the twiner whereby the cleaning of the yarn is improved and tho
passage of bad ends and knots in doubling the yarn is entirely prevented.
Such being the nature and object of our said invention we will now proceed to
describe in detail the manner in which the same is to be performed or carried into
practical effect, which will be readily understood on reference to the sheet of
drawings hereunto annexed and the following explanation thereof.
Fig. 1. is a sectional view of so much of a "twiner" as is necessary to illustrate
our invention. Fig. 2. is a front view of our improved guide plate, and Fig. 3. is
a section of the "slide " drawn to a larger scale and showing more clearly the
application of our invention.
a, a is part of the framing of the "twiner" b, b.the "slide," c, c the spindles and
d, d the creel, e, e is the slotted guide plate which we make wider than heretofore,
and we strengthen the same also by the addition of a bar f, f (see Fig. 2) or
otherwise, and we cut the notches or slots g, g in the same deeper than usual, and
we cause the yarn to traverse constantly up and down in the said notches or slots
(as indicated by the dotted lines in Fig. 3.) so as to keep them quite clear from dirt
by fixing the said guide-plate in the position, and in the manner following: that is
to say, we fix the guideplate e, e to the slide b, b of the "twiner" at the back
thereof, or on that side nearest the spindles c, c as shown on the drawing and we
secure it thereto in such a way that there is a space left between the guide-
plate e, e and the back of the slide b, b (see Fig. 3) for dirt and lumps to fall down
through such space.
The position of the slide 6, 6 being higher than that of the spindles c, c it will be
evident that the angle of inclination of the thread or yarn between the slide and
the spindles will be varied as the slide in traversing to and fro moves from the
position in which it is drawn at the left hand of Fig. 1. to the position in which it
is drawn in dotted lines in the same Fig. and back again and by attaching the said
guide-plate to the back of the slide as previously mentioned this varying angle of
inclination will cause the yarn to rise and fall alternately in the slots or notches
and thus keep them quite clear of dirt.

page_text: By the use of this invention a finer notch or slot can be employed than heretofore
and the passage being kept quite clear, and no accumulation of dirt being possible,
a cleaner and better yarn will be produced.
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
In twiners employed for doubling yarn the particular construction of notched
guide-plate as herein before described and illustrated by the drawings annexed and
the application of the same to the back of the "slide" substantially in the manner
and for the purposes herein before set forth.
