PROVISIONAL SPECIFICATION.
Improvements in or applicable to the Drawing In and Checking
Mechanism of Self Acting Mules for Spinning.
I THOMAS STOTT of 34 Cheetham Street, Shaw near Oldham in the County
of Lancaster, Spinner, do hereby declare the nature of this invention to be as
follows:
:-
This invention relates to the mechanism which effects the drawing in and
checking of the carriages of self acting mules for spinning, the object of the
invention being to render the said motions more perfectly even in their action
than is at present possible.
For this purpose instead of attaching the ends of the drawing in bands or
ropes to the carriage, as usual, I provide scrolls upon the back shaft, actuating the
said shaft by a spring pawl and ratchet wheel, and I fasten the ends of the said
bands or ropes to eyes on these scrolls, so that when the scroll shaft is rotated it
will actuate the back shaft and the squaring bands will draw in the carriage.
In some cases the two drawing in scrolls on the back shaft may be made in one,
and a single band passed through an eye or its equivalent thereon, and arranged to
be wound from these scrolls upon the two scrolls on the scroll shaft, the two ends
of the band being fixed to these last named scrolls respectively.
I propose also to increase the strength of the squaring band at the headstock
to compensate for the increased strain thereon caused by disconnecting the scroll
bands from the carriage.
The checking band instead of checking the carriage as before will pass up to
a scroll upon the back shaft and so check the latter, as the scrolls of this band will
be reversed in action to those of the drawing in bands, or band.

Improvements in or applicable to the Drawing In and Checking
Mechanism of Self Acting Mules for Spinning.
I THOMAS STOTT of 34 Cheetham Street, Shaw, near Oldham, in the County
of Lancaster, Spinner, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
This invention relates to the mechanism which effects the drawing in and checking
of the carriages of self acting mules for spinning, the object of the invention
being to render the said motions more perfectly even in their action than is at
present possible.
The invention will be readily understood on reference to the accompanying sheet
of drawings, of which
Fig. 1 is a face view, and Figs. 2 and 3 views taken from each side of Fig. 1,

page_text: shewing so much of the headstock of a spinning mule as is necessary to illustrate
my invention.
Fig. 4 is a face view and Fig. 5 an end view shewing a modification hereafter
referred to.
a is the frame of the beadstock, 6 is the back shaft and c the scroll shaft.
Instead of attaching the ends of the drawing in bands or ropes to the carriage,
as usual, I provide scrolls & mounted loosely upon the back shaft b, actuating
the said shaft by a spring pawi and ratchet wheel d² keyed or fixed thereon
or equivalent devices, and I fasten the ends of the said bands or ropes & to eyes d³
on these scrolls, so that when the scroll shaft c is rotated it will actuate the
back shaft through the scrolls ee and the squaring or draw bands alone will
draw in the carriage.
In some cases the two drawing in scrolls d d on the back shaft b may be made in
one (as seen on Fig. 4) and a single band a passed round a projection d' (see also
Fig. 4) or through an eye or its equivalent thereon, and arranged to be wound
from these scrolls d d upon the two scrolls e e on the scrolls shaft c the two ends of
the band being fixed to these last named scrolls respectively. I sometimes employ
two sets of scrolls d d e e one on each side of the headstock as seen at Fig. 4.
I propose also to increase the strength of the squaring or draw bands at the
headstock to compensate for the increased strain thereon caused by disconnecting
the scroll bands from the carriage.
of
The checking band y instead of checking the carriage as before will pass up to
a scroll upon the back shaft 6 and so check the latter, as the scrolls f and
this band will be reversed in action to those of the drawing in bands a x, or
band. The scroll f may be fixed upon the back shaft or connected thereto by
a ratchet and pawl as shewn on the drawings.
The band y may be tightened or adjusted by passing round an adjustable pulley h
at the outer end of the headstock (see Fig. 5).
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination of scrolls and bands or scrolls and band for actuating the
back shaft from the scroll shaft in such a manner that the carriage is connected to
the squaring or draw bands and scrolls on the back shaft only and is not at any
time drawn in directly by the scroll shaft as usual, substantially as hereinbefore
described and illustrated by the annexed drawings.
2. The combination of scrolls and band for checking the back shaft instead of
checking the carriage as usual substantially as hereinbefore described and
illustrated by the annexed drawings.
3. The combination of scrolls and bands for actuating and checking the back
shaft, for drawing in and checking the carriage directly from the said shaft only,
substantially as hereinbefore described and illustrated by the annexed drawings.
