Sealed the 7th October 1876, and dated the 4th August 1876.

JOHN LEIGH TAYLOR, of the Firm of Thomas Taylor & Sons, of the Grecian
Mills, Bolton, in the County of Lancaster, Cotton Spinners, and ROBERT RAMSDEN,

AND DOUBLING."
"t
Our Invention is applicable to both self-acting and hand mules, and it consists in
certain improved arrangements of parts for keeping the yarn at the proper tension
previous to winding it on the spindles.
In performing our Invention we carry the taking-up chain around a pulley or
cam mounted at the end of a lever or slide which is connected to the carriage
square; the chain then passes under a pulley or cam on the faller lever slide, and
then it is wound on the backing-off scroll When the carriage arrives at the
end of its stretch the lever or slide comes against a catch or stop bracket, which
pushes the lever or slide back, and tightens the backing-off chain, thereby taking
up the slack of the chain, and bringing the faller wire near to the yarn pre-
paratory to backing off. The faller wire acts on the yarn at the moment when
the backing off takes place, thereby preventing snarls, and producing a better nose
to the cop.

Our Invention is applicable to both self-acting and hand mules, and it consists in
certain improved arrangements of parts for keeping the yarn at the
previous to winding it on the spindles.
proper
And in order that our Invention may be fully understood we will proceed to
describe the accompanying Sheet of Drawings, in which Fig. 1 represents an eleva-
tion of the carriage and part of the headstock of a self-acting mule for spinning
and doubling, to which our improvements are applied. a is the carriage; b, the
carriage square; c, the spindles; d, the faller shaft; e, the counterfaller shaft; f
the faller segment keyed on the faller shaft; g, the backing-off chain; i, the drum
for driving the spindles; and j, the backing-off chain motion lever.
All these parts and the various parts of the headstock are made in the usual
manner.
The chain g is secured above to the faller segment fas usual, and in passing from
thence to the ordinary backing-off scroll, or to a bush on the axle of the drum i it
is taken around the pulley or cam m¹ mounted on a stud at the end of the lever or
slide m, which is connected to the carriage square by bolts passing through slots.
The chain g then passes under a guide pulley n, and then over a pulley or cam j
on the backing-off chain motion lever 1, and then it is wound on the backing-off
scroll, or on a bush fixed to the axle of the tin drum i. When the carriage arrives
at the end of its stretch the end of the lever or slide m comes against a catch or
stop bracket o, which pushes the lover or slide m back, and tightens the backing-off
chaing, thereby taking up the slack of the chain, and bringing the faller wire near
to the yarn preparatory to backing off. The faller wire acts on the yarn at the
moment when the backing off takes place, thereby preventing snarls, and producing
a better nose to the cop. The stop bracket o is adjustable to allow the end of
the slide m to act against it sooner or later, according to the length of stretch
required.
Fig. 2 represents a modification of our Invention. In this case the lever or
slide m and the pulley or cam m¹ are dispensed with, and when the carriage is
nearly out the backing-off chain itself comes against and is acted upon by the
cam, stud, or pulley p, which is connected to the framing of the headstock, and the
position of which can be regulated so that the chain g may come earlier or later in
contact with it, as before described in reference to the stop o, in Fig. 1.
Having thus stated the nature of our Invention, and described two convenient
modes of performing the same, we wish it to be understood that we do not intend
to limit ourselves to the details given, as the same must be varied according to the
peculiar construction of the self-acting or hand mule to which it is applied; and we
claim, the improved combinations of machinery shewn and described, or any modifi-
cation of the same, for tightening the backing-off chain when the carriage is nearly
out, whereby the faller is brought down previous to backing off for the purposes
described.
In witness whereof, we, the said John Leigh Taylor and Robert Ramsden,
have hereto set our hands and seals, this Thirty-first day of January, One
