IMPROVEMENTS IN APPARATUS EMPLOYED IN MULES FOR SPINNING
Year: 1884

page_text: We, ROBERT CHARLES HAWORTH, Cotton Spinner, and ROBERT RYLES, Spinning
Overlooker, both of Hindley near Wigan in the County of Lancaster, do hereby
declare the nature of our Invention for "IMPROVEMENTS IN APPARATUS
EMPLOYED IN MULES FOR SPINNING." to be as follows:-
Our invention has reference to improvements for effecting the operation of
winding in machinery known as mules for Spinning, particularly to those well-
Platt's" Self-acting Mules, and consists in means for the better
adjustment of the spring for operating the winding apparatus.
known as
26
We accomplish this by providing suitably shaped metallic filling or strength-
ening pieces on the outside of the spring which operates the winding catch
or ratchet wheel in self-actor mules, through which passes a bolt, stud or other
equivalents, by which the spring is held firmly on the boss on the winding
wheel on winding shaft; the spring is provided on the inside with strips or linings
of leather to rest on the boss of the said winding wheel.
Under the present system when these leather strips become worn or the tension
of the spring decreases, the spring is liable to come loose, consequently does not
perform its work efficiently, causing the spring to slip on the ratchet wheel it
operates, and thus causes miswinding which is very detrimental to good spinning.
By our improvement the spring is always kept up to its work, thus preventing
any inconvenience from slipping, at the same time being easy of adjustment, and
can be altered or set as required without stopping the machinery, as well as that of
prolonging the life of the winding apparatus in the kind of mules for spinning
before described.

page_text: We, ROBERT CHARLES HAWORTH, Cotton Spinner, and ROBERT RYLES, Spinning
Overlooker, both of Hindley near Wigan. in the County of Lancaster. do hereby
declare the nature of our Invention for "IMPROVEMENTS IN APPARATUS EMPLOYED
IN MULES FOR SPINNING." and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :—
Our invention has reference to improvements for effecting the operation of
winding in machinery known as mules for spinning, and consists in means for the
better adjustment of the spring for operating the winding apparatus.
We accomplish this by providing suitably shaped metallic filling or strengthening
pieces on the outside of the spring which operates the winding catch or ratchet-
wheel in self-actor mules, through which passes a bolt, by which the spring is held
firmly on the boss on the ratchet or winding wheel on winding shaft. The spring
is provided on the inside with strips of leather to rest on the boss of the said
winding wheel.
Under the present system when the leather strips become worn, or the tension of
the spring decreases, the spring is liable to come loose, consequently does not perform
its work efficiently, causing the spring to slip on the ratchet or winding wheel it
operates; with the result of miswinding which is detrimental to good spinning.
In order that our invention may be better understood we will proceed to describe
the same by reference to the annexed sheet of drawings, similar letters of reference
indicate like parts throughout the drawings.
Figure. 1. represents a side view or elevation of the spring A supported on the
boss B on the ratchet or winding wheel for operating the winding shaft M. The
spring A is provided with the filling or strengthening pieces C on the outside as
shewn; having suitable holes, as well as the spring, to admit the screwed bolt D.
This bolt is provided with the nut E and check uut F, the latter being for the
purpose of locking the nut E in position after the requisite tension is attained, thus
firmly securing the spring in position on the boss B of the ratchet or winding shaft
wheel.
To prevent the bolt D turning when operated by the nut E, the underside of the
head H is made square at I; the hole in the filling piece being made to correspond.
The leather strips G are provided as usual on the inside of the spring A, for the
purpose of resting or sitting on the boss B, and thus prevents any wearing of the
metallic parts; the spring being easily adjusted in case the leather strips & wear,
by tightening the bolt D as before described.
Figure 2 is a plan of the spring with our improvements applied.
Figure 3 is a sectional elevation through the spring A and filling pieces C at the
point where the bolt D passes through them.
By the application of our improvements the spring A is always kept up to its
work, with the result of dispensing with the inconvenience from slipping; being
easy of adjustment, which can be performed without stopping the machinery.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed we declare that what
we claim is :-
The improved apparatus attached to the spring A for operating, the ratchet or

with the nuts E and F, and the filling or strengthening pieces C, for the purposes
herein set forth, substantially as described and shewn on the drawings.
