PROVISIONAL SPECIFICATION.
Improvements in Tightening Apparatus for Rim Bands on
Spinning Mules.
.
I, SAMUEL ROWBOTTOM, of Meadow Mills, Glossop, Derbyshire, Cotton
Spinner, do hereby declare the nature of this invention to be as follows:-
The improvements relate to mules for spinning, and have for object to provide
more adequate means for tightening the rim band, or taking up the slack therein,
without stopping the mule.
In apparatus as at present constructed, the rim band is caused to pass over a
single carrier pulley actuated by racks, slide-screws, or the like, which carrier
pulley is thereby capable of being moved, to a certain extent, to regulate the tension
on the band.
Such arrangement, however, does not give the requisite scope for taking up the
slack.
To effect my improvements, I employ one or more additional carrier pulleys,
with their necessary racks, slide-screws, and brackets, or other adjustable means,
which I mount upon the headstock of the mule, at convenient parts thereof, and in
such manner or position as may be most effectual for the purpose.
By this additional means, the rim band aforesaid, which passes over the carrier
pulleys, may be tightened to any desired extent.
Variations in detail, such as the position of the apparatus on the headstock, the
form thereof, and the mechanical mode of adjusting the same for tightening
purposes, may be made without departing from the peculiar character of the
invention.

COMPLETE SPECIFICATION.
Improvements in Tightening Apparatus for Rim Bands on
Spinning Mules.
I, SAMUEL ROWBOTTOM, of Meadow Mills, Glossop, Derbyshire, Cotton
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 :-
The improvements relate to mules for spiuning, and have for object to provide
more adequate means for tightening the rim band, or taking up the slack therein,
without stopping the mule.
In apparatus as at present constructed, the rim band is caused to pass over a
single carrier pulley actuated by racks, slide-screws, or the like, which carrier
pulley is thereby capable of being moved, to a certain extent, to regulate the
tension on the band.
Such arrangement, however, does not give the requisite scope for taking up the
slack.
To effect my improvements, I employ one or more additional carrier pulleys,
with their necessary racks, slide-screws and brackets, or other adjustable means,
[P77

page_text: which I mount upon the headstock of the mule, at convenient parts thereof, and in
such manner or position as may be most effectual for the purpose.
By this additional means, the rim band aforesaid, which passes over the carrier
pulleys, may be tightened to any desired extent.
But that the improvements may be better understood I will, with the aid of the
accompanying drawings, proceed more fully to describe means employed by me.
DESCRIPTION OF DRAWINGS.
The figure shews an elevation of part of a mule headstock, provided with
apparatus for tightening the rim band according to my improvements.
The same letters indicate corresponding parts wherever they occur.
a is a special carrier pulley, employed to supplement the ordinary carrier pulley b,
both of which pulleys in the example shewn, turn upon pins, studs, or other
projections attached to blocks c, c, which blocks receive motion, when desired, from
the screws d, d, actuated by hand-wheels e, e, and mounted within the brackets or
projections h, h.
k, is the rim band, which passes from the carrier pulley b, which, in this case, is
a non-adjustable pulley, then over the special adjustable carrier pulley a, and under
the ordinary carrier pulley b, to the actuating parts of the mule.
Variations in detail may be made, such as the position of the apparatus on the
headstock, the form thereof, and the mechanical mode of adjusting the same for
tightening purposes, without departing from the peculiar character of the
invention.
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 :-
:―
In apparatus for tightening the rim bauds of mules for spinning, the combination
of one or more special carrier pulleys, one of which is adjustable, with the ordinary
carrier pulley, and with brackets or projections for supporting the same, in manner
substantially as herein shewn and described.
