page_text: Improvements in Self Acting Mules.
I, ROBERT TAYLOR, of Asa Lees and Company Limited, Soho Iron Works,
Oldham, in the County of Lancaster, Machine Maker, do hereby declare the
nature of this invention to be as follows:-
My invention relates to those self acting mules, such as woollen and wasic
mules, in which two scrolls are employed on different axes and turning in
opposite directions, one being the drawing out scroll and the other the drawing
out check scroll.
It frequently happens that when one of the scrolls has been taken off its
stud or shaft it gets replaced out of its true relative position to the other scroll
and in consequence an excessive strain is put upon one or other of the ropes
connecting the scrolls to the carriage thereby frequently causing breakages of
the ropes or machine.
The object of my invention is to obvinte this defect and I accomplish this
object by employing flanged gears to connect the driving shaft with the driven
or drawing out scroll shaft and I cut away a small portion of the flange at a
certain point on each gear, so that the two-when on their shafts-can only
be slipped into gear at this point, thereby insuring that the two scrolls are in
their true positions relatively to one another; or instead of employing flanged
gears and cutting away portions of their flanges I might use gears one having
an extra large tooth and the other a corresponding recess or any equivalent
device for effecting the same purpose.

pel Acting mules.
I, ROBERT TAYLOR, of Asa Lees and Company Limited, Soho Iron Works,
Oldham, in the County of Lancaster, Machine Muker, 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:-
My invention relates to those self acting mules, such as woollen and waste
mules, in which two scrolls are employed on different axes and turning in
opposite directions one being the drawing out scroll and the other the drawing
out check scroll.
It frequently happens that when one of the scrolls has been taken off its

and in consequence an excessive strain is put upon one or other of the ropes
connecting the scrolls to the carriage thereby frequently causing breakages of
the ropes or machine.
The object of my invention is to obviate this defect and I accomplish this
object by employing flanged gears to connect the driven scroll shaft with the
check scroll, and I cut away a small portion of the flange at a certain point
on each gear, so that the two-when on their shafts--can only he slipped into
gear at this point, thereby insuring that the two scrolls are in their true
positions relatively to one another.
In the accompanying two sheets of drawings-
Figure 1 is an elevation of the two scrolls with the framing removed.
Figure 2 is a plan view of the same but showing the framing.
Figure 3 is an elevation of the gearing and Figure 4 is a sectional plan of
Fig. 3.
In these views. designates the framing, the driven scroll shaft, c the
drawing out scroll which is fast thereon, d the flanged gear also fast on the
scroll shaft b. e is the other flanged gear which is formed or combined with
the boss of the drawing out check scroll f both being mounted loose upon the
shaft and being held in position at one end by the framing a and at the other
end by a set hoop or collar h.
As clearly shown in the detail view. Fig. 3, part of the flange of the
gear and a corresponding part of the flange e' of the gear are cut away so
that the two wheels can only be slipped into pear with each other at this point.
Consequently when for any purpose the drawing out check scroll is removed
from its shaft, which it can be at any time by taking off the set hoop h, the
said scroll can only be replaced with its wheel è in gear with the wheel when
the two wheels are in the positions indicated in Fig. 3. which insures the two
scrolls c and being in their true positions relatively to one another.
Instead of employing flanged gears and cutting away portions of their flanges
I might use gears one having an extra large tooth and the other a corresponding
recess, or any equivalent device for effecting the same purpose.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed declare that what
I claim is:.
1. In a self acting mule in which two scrolls are employed on different axes
and turning in opposite directions, the use and application of means substan-
tially as herein set forth for insuring that the two scrolls can only be slipped
into gear in their true positions relatively to one another.
2. The combination with the drawing out scroll c, its shaft b and flanged
gear d having part of its flange removed, of the flanged gear having a
corresponding part of its flange removed, the drawing out check scroll f,
shaft g and set hoop or equivalent all substantially as and for the purposes
herein described and as illustrated by the accompanying drawings.
