PROVISIONAL SPECIFICATION.
Improved Traverse Motion for Spinning Mules, Slubbing, Roving,
and Throstle Frames for Cotton or Wool.
THOMAS AINSWORTH 106 Acqueduct Street Preston Lancashire, Mechanic
do hereby declare the nature of this invention to be as follows:-
Consisting of one large wheel, and one small wheel, with an eccentric attached
to each wheel in the centre, giving motion to two levers, and one traverse rod.
The lever on the small wheel at one end works on the eccentric, the other end
having a stud to which is attached the second lever, which also works on an
eccentric fixed on large wheel in its centre, the other end of same lever having a
stud to work the traverse rod.
The motion for working the above is obtained from the back roller by means
of a worm wheel, which is geared into the large wheel mentioned above.

Improved Traverse Motion for Spinning Mules, Slubbing, Roving,
and Throstle Frames for Cotton or Wool.
I THOMAS AINSWORTH Mechanic of 106 Aqueduct Street Preston in the
County of Lancaster do hereby declare the nature of this invention and in what
maner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention relates to improvements in apparatus for traversing the yarn
guides employed in machines for preparing and spinning cotton or other fibrous
materials, and is for the purpose of imparting a variable traverse to the yarn
guides and preventing the covered rollers being cut or nicked by the yarn, and
the object above stated is effected as indicated by the accompanying sheet of
drawings in which-
Figure 1 is a plan of my improved traverse motion applied to the traverse rod
of a spinning mule.
Figure 2 is a side elevation of the same with one eccentric lever shown in
section.
Figure 3 is an end elevation with the other eccentric lever shown in section and
Figure 4 is a plan of the traverse motion on a larger scale.
The lines of rollers are designated a, b, and c, the traverse rod d upon which
are the yarn guides e, and back roller worm f. All the foregoing parts are of the
ordinary construction.
According to the present improvements a bracket g is fixed to the framing g'
and to which is secured studs h, k and I carrying wheels h¹, k¹ and 1.
Attached to or formed with the wheel is an eccentric m forming the axis of
and upon which is fitted the lever n. To one end of this lever is secured a stud o¹
upon which is fitted one end of a connecting rod o, the other end of this connecting
D

page_text: rod being attached to the traverse rod d by stud o¹¹¹. The opposite end of lever n
fits upon the stud p¹ which is secured to one end of the lever p the other end
fitting over the eccentric r formed with or attached to the wheel 11.
In action the worm on the back roller driving the eccentric r through
wheels h¹, k¹ and traverse is given to the traverse rod d through the levers p and n
and connecting rod o.
The eccentric m rotating with the wheel n¹ causes the axis of the lever n to be
constantly varying and imparting a variable traverse to the traverse rod d, the
length of traverse being adjusted as required by altering the position of stud o' in
the slot oll.
Although shown and described as applied to a spinning mule my improved
traverse motion can be applied to slubbing, roving, and throstle frames.
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:
The combination with the traverse rod d of the eccentrics r and m, levers p
and n, connecting rod o and wheels, k¹ and applied and operating substantially
as described and as illustrated in the drawings.
Dated this 8th day of May 1895.
