Improvements in or relating to Self Acting Spinning Mules.
I, JOSEPH MOORHOUSE of 15 Oak Street Shaw near Oldham Lancashire
Mill Manager 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 :-
My invention relates to mules for spinning cotton and other fibrous substances
and refers to improved means for gradually relieving the counter faller shaft of the
weight of the counter faller lever or "salmon-head" during the backing off
motion and gradually applying said weight at the commencement of the winding
on of the yarn.
In carrying out my invention I employ a "bell-crank lever or a lever having
two arms at right angles to each other which lever is pivoted at the junction of
its arms on a stud or bolt on the side of the ordinary "salmou-head" lever. One
of the arms of this bell crank lever assumes a vertical position and is connected
to the ordinary counter faller chain for operating the counter faller and the other
arm of this lever assumes a horizontal position and is curved on its under side.
This curved arm is designed to come against and rest upon a stationary incline
and to serve the purpose of gradually relieving and applying the weight of the
"salmon-head " in the manner hereinafter described.
As the mule carriage reaches the end of its outward traverse the curved arm of
the crank lever comes upon the incline aforesaid. The "backing off" now takes
place causing the salmon head lever to be lowered the weight of which is now
received by the point of the curved arm of the bell crank lever and the said arm
owing to its curved formation rolls or slides upon the incline until the point of rest
is more or less beneath the supporting bolt thus gradually taking up the weight of
the "salmon-head" and relieving the counter faller as desired. In order now to
apply the weight of the "salmon-head" at the instant of winding on the yarn
the bell crank lever as the carriage moves away runs or slides off the incline the
curved arm of the lever gradually taking up the weight and applying it to the
counter-faller.
On the accompanying drawing
Fig. 1 is an end elevation of a mule carriage with my improvements shewn applied
thereto.
Fig. 2 is an enlarged detail view.
In accordance with my invention A is the bell crank lever mounted upon a stud
or bolt B on the side of the ordinary salmon-head lever C. The upright arm of
lever A is connected as illustrated with the faller-shaft chain D and the horizontal
arm is curved on the under side as shewn. The normal position of the lever is
shewn in Fig. 1 and as the mule carriage reaches the end of its outward traverse
the point of the horizontal arm comes in touching contact with or rests upon the
incline E. As soon as the salmon-head weight is to be relieved it will be evident
that the lowering of the "salmon-head" will cause the lever A to receive the weight
thereof and in so doing such lever owing to its curved edge A rolls or slides upon
the incline E and gradually takes up the weight and assumes the position shewn in
dotted line in Fig. 2 when the weight is really carried by the bolt B and the
slack of the chain D is more or less absorbed or taken up by the peculiar angle
assumed by the arm A.
On the carriage commencing to draw in or wind on the yarn the rolling or
sliding action of the lever is reversed commencing from the point of rest to the
tip of the lever thus causing the weight to be gradually applied again without
any shock or strain on the yarn.

page_text: A treble armed or "anchor lever" (see Fig. 3) or a lever with a rounded end
(see Fig. 4) might be used in lieu of the bell crank lever and would act more or less
in a similar manner but I prefer the arrangement previously described.
Having thus 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 self acting spinning mules the use and employment in conjunction with the
"salmon-head lever of a bell crank or other lever mounted and operating
substantially as and for the purpose hereinbefore described and illustrated on the
accompanying drawing.
