Improvements in or Applicable to Mules and Twiners.
Year: 1886

We JOSEPH MOORHOUSE of 25 Blakelock Street, Shaw, in the County of
Lancaster, Mule Overlooker, and JOHN ASHTON of Oak House, Beal Lane, Shaw,
in the County of Lancaster, Cotton Spinner, do hereby declare the nature of
our invention to be as follows:-
The object of this invention is to obviate the great wear and tear upon the
counter belts of Mules and Twiners in consequence of the width of such belts and
the great power required to move the same from the fast on to the loose pulleys or
vice versa.
In performing our invention instead of having a single wide strap as heretofore,
we employ two or more narrower straps and a corresponding number of fast and
loose pulleys upon the rim shaft. These narrower straps thus only require to be
moved to and fro by the strap fork a distance corresponding to their width and as
a consequence less power is required and greater rapidity of change is also effected.
Doted this 3rd day of August 1886.

We JOSEPH MOORHOUSE of 25 Blakelock Street, Shaw, in the County of
Lancaster, Mule Overlooker and JOHN ASHTON of Oak House, Beal Lane, Shaw
in the County of Lancaster, Cotton Spinner do hereby declare the nature of our
invention 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 obviate the great wear and tear upon the
counter belts of Mules and Twiners in consequence of the width of such belts and
the great power required to move the same from the fast on to the loose pulleys or
vice versa.
In performing our invention instead of having a single wide strap as heretofore
we employ two or more narrower straps and a corresponding number of fast and
loose pulleys upon the rim shaft.
On the accompanying drawing Fig. 1 represents a plan view of so much of the
head stock of a mule as is necessary to explain our improvements which are
illustrated as applied thereto.
In performing our invention instead of having a single pair of wide pulleys (fast
and loose) upon the rim shaft (a) and driven by a single wide belt (which owing
to its width has been difficult to move to and fro and has resulted in great wear
and tear upon the edge of the belt) we employ two narrower fast and loose pulleys
marked (b. b.) and (c. c.) respectively mounted upon the same rim shaft (a.) and
which are driven by a pair of belts of corresponding narrower width from a single
drum of the requisite diameter upon the counter shaft the strap fork (d.) in this
case being arranged with a double head (e.) as illustrated to move the two belts to
and fro simultaneously.
In this manner and with these narrower belts we obtain a better grip upon the
pulleys than that afforded by the wide belt hitherto used whilst in practice it is
also found that the driving is steadier and that as these narrower belts only
require to be moved to and fro a distance corresponding to the width of the fast
pulleys as a consequence less power is required to move them and greater rapidity
of change is also effected.
Instead of two sets of fast and loose pulleys being employed as hereinbefore
described and illustrated it will be apparent that three or more sets might be so
employed and it will be further obvious that instead of having a double headed
strap fork and rod as hereinbefore described and illustrated that a separate strap
fork and rod could be employed for each driving belt and operated simultaneously
but these we should consider to be a modification of our invention.
. Although only hereinbefore described and illustrated as applied to a mule it will
be obvious that our improvements are equally applicable to Twiners.
We wish it to be understood that we are well aware that a double pair of fast
and loose pulleys have hitherto been sometimes used upon the rim shaft of a mule
but the same have been driven at different speeds froin different sized pulleys on
the counter shaft and with a different object to that of our invention and this we
only mention to say that we make no claim to double pairs of pulleys when so
mounted and driven at different speeds.

page_text: Having thus particularly described and ascertained the nature of our inven
tion and in what manner the same is to be performed we declare that what we
claim is:-
1st. The improved method of driving the rim shaft of a Mule or Twiner sub-
stantially as and for the purposes hereinbefore described.
2nd. In a Mule or Twiner the employment of two or more fast and loose pulleys
mounted upon the rim shaft and driven simultaneously by a corresponding number
of belts from the counter shaft substantially as and for the purposes hereinbefore
described.
3rd. In a Mule or Twiner the employment of two or more fast and loose pulleys
upon the rim shaft driven simultaneously by a corresponding number of belts from
the counter shaft in combination with a strap fork or forks capable of moving such
belts to and fro simultaneously substantially as hereinbefore described.
