PROVISIONAL SPECIFICATION.
Improvements in or applicable to Self-acting Mules.
I, WILLIAM EDWARD DIXON, of 159, Deane Church Lane, Rumworth, Bolton,
in the County of Lancaster, Operative Spinner, do hereby declare the nature of my
said invention to be as follows:-
This invention relates to improvements in or applicable to self-acting mules for
spinning cotton and other fibrous substances and is designed to dispense with the
quadrant, quadrant arm, winding bands, and their appendages, and substitute
therefor simple and efficient contrivances to effect more regular winding, improve
This I accomplish
the nosing motion, and produce better yarn than hitherto.
in the following manner:-On the cylinder shaft in lieu of the present parallel
winding drum I mount a differential scroll which is driven from a similar scroll by
a chain or its equivalent. On the side of one of the scrolls is fixed a spur. wheel
gearing into a rack mounted in a box or casing on the mule room floor. By the
travelling movements of the mule carriage a catch or its equivalent is operated on
the side of the rack to automatically swivel or alter the position of the differential
winding scroll according to the requirements necessary for building the cop on the
spindle.
To take up any slack that may take place in the chain connecting the
differential scrolls suitable drums or their equivalents are provided driven or
operated from any convenient part of the mule. In conjunction with this apparatus
I dispose in any convenient position an arm provided with suitable mechanism to
operate a screw or its equivalent for the purpose of allowing the nosing peg to be
altered or moved automatically by the travelling movements of the mule carriage.
The whole of the mechanism is mounted in suitable bearings attached to the mule
or otherwise in any convenient manner according to the class or make of mule my
invention may be applied to.

Improvements in or applicable to Self-acting Mules.
I, WILLIAM EDWARD DIXON, of 159, Deane Church Lane, Rumworth, Bolton,
in the County of Lancaster, Operative Spinner, do hereby declare the nature of my
said 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 improvements in or applicable to self-acting mules for
spinning cotton and other fibrous substances and is designed to dispense with the
quadrant, quadrant arm, winding bands, and their appendages, and substitute
therefor simple and efficient contrivances to effect more regular winding, and

On the cylinder shaft in lieu of the present parallel winding drum I mount a
differential scroll which is driven from a similar scroll by a chain or its equivalent.
On the side of one of the scrolls is fixed a spur wheel gearing into a rack mounted in
a box or casing on the mule room floor. By the travelling movements of the mule
carriage a catch or its equivalent is operated on the side of the rack to automatically

DESCRIPTION OF DRAWINGS.
Fig. 1 is a longitudinal elevation of my invention for dispensing with the quadrant,
quadrant arm, and their appendages in self-acting mules.
Fig. 2 is a part sectional end elevation.
Fig. 3 is a part plan.
Fig. 4 is a plan of box or casing on mule room floor with rack removed.
Fig. 5 is a front elevation of ratchet wheel, lever, and "pawl" to rotate screwed
spindle in box or casing to operate rack, and
Fig. 6 is a sectional elevation through line A¹ B' in Fig. 1.
In all the figures the same letters are employed to indicate corresponding parts.
A is the tin roller shaft; B a spur wheel geared into the spur wheel C on the
shaft D;
E the mule carriage, and F the back framework of the mule. On the
shaft D' is mounted the differential scroll G in lieu of the parallel winding drum
at present employed in self-acting mules. In the fixings H attached to the mule
carriage E is mounted the shaft I, on which is fixed the differential scroll J; the
latter being connected to the differential scroll G by the chain K. The shaft I is
fitted with the spur wheel L gearing with the adjustable rack M mounted in the
box or casing N secured to the mule room floor. The box or casing N is constructed
as shown in section in Fig. 2 to allow of a sliding movement being given to the
rack M. The latter is mounted on the screwed spindle O; the latter being rotated
by the ratchet wheel P, "pawl" Q, and lever R on the shaft S in the bearings T
on the side of the box or casing N. On the shaft S is fixed the adjustable lever U
against which the projection V strikes or operates to swivel the shaft S to operate
the ratchet wheel P and screwed spindle O to automatically swivel or alter the
position of the differential winding scroll J each outward run of the mule carriage E
according to the requirements necessary for building the cops on the spindles.
After the mule carriage E has commenced to make an inward run and the adjustable
lever U is released from the projection V the levers U and R and the "pawl" Q
are re-set by the weighted lever W on the shaft S ready for the next outward run
of the mule carriage E to automatically adjust the rack M. The shaft D is fitted
with the band pulley Z, which is operated by a band and weight, as in existing
mules, to take up any slack that may take place in the chain K connecting the
differential scrolls G and J.
Although I have not shown a nosing peg I would have it understood that I can
fix one, if necessary, on the framework of the mule to operate on the chain K when
the mule carriage is completing each inward run, but I lay no claim thereto.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I would have it understood
that I do not confine myself to the precise details and configuration of the parts
have shown and described, as the same may be varied according to the class or
make of mule it may be applied to without departing from the principle of my
invention, but what I claim is :-
1. In self-acting mules the use and employment of differential scrolls mounted on
shafts or centres and connected by a chain, operated by a spur wheel and rack by
the travelling movements of the mule carriage for the purpose specified substantially
as described.
2. In combination with the differential scrolls G and J, chain K, and spur
wheel L, the adjustable sliding rack M mounted in the box or casing N to
automatically swivel or alter the position of the differential winding scrolls

page_text: according to the requirements necessary for building the cops on the spindles,
substantially as described.
3. In combination with the sliding rack M the use of apparatus consisting of the
shaft S in the bearings T, levers R and U, "pawl" Q, ratchet wheel P, weighted
lever W, and screwed spindle O, operated automatically by the projection V each
outward run of the mule carriage, substantially as described.
4. The construction, combination, and arrangement of parts forming my invention
for dispensing with the quadrant, quadrant arm, and their appendages employed in
self-acting mules, substantially as described and illustrated by the drawings.
Dated the 23rd December 1890.
