Improvements in the Spindles of Self Acting Mules and Twiners.
We, GEORGE HESKETH, of Linwood, Astley Bridge, near Bolton, in the County
of Lancaster, Cotton Spinner, and WALTER HAMER, Junior, of Ash Bank, Astley
Bridge aforesaid, Mill Manager, do hereby declare the nature of this invention
to be as follows:-
Our invention relates to improvements in the spindles of self acting mules
and twiners the object of our invention being to prevent the yarn from being
pulled or drawn off the spindle blade and point during the outward run of the
carriage.
To accomplish this object we cut a small notch or groove straight, diagonally
or spirally across or partly across the face and near the top of the spindle in a
direction either corresponding with or parallel to the layers of yarn as they are
wrapped upon the spindle blade or otherwise. The upper edge of this notch or
groove is preferably made at a right angle or thereabouts to the axis of the
spindle or otherwise shaped to prevent the yarn being drawn off the spindlo
blade and point when the carriage is running out. The lower edge of the notch.
or groove is bevelled off so as not to hold the yarn or interfere with backing off.
Instead of the notch described a groove could be cut at any angle from near the
top of the spindle to a point below, or we could cut two grooves in opposite
directions so as to be able to spin with spindles running in either direction-for
weft or twist, or as an alternative a piece of metal might be secured to the spindle
in such a way as to effect the same object.
An important advantage attained by the use of our invention is that we are
enabled to set the spindles at a greater angle relatively to the vertical line without
any risk of the yarn slipping off the points of the spindles whereby we improve
the spinning and make better noses on the cops.

and ascertained in and by the following statement:-
Our invention relates to improvements in the spindles of self acting mules
and twiners the object of our invention being to prevent the yarn from being
pulled or drawn off the spindle blade and point during the outward run of the
carriage.
To accomplish this object we cut a small notch or groove straight, diagonally
or spirally across or partly across the face and near the top of the spindle in a
direction either corresponding with or parallel to the layers of yarn as they are
wrapped upon the spindle blade or otherwise. The upper edge of this notch or
groove is preferably made at a right angle or thereabouts to the axis of the
spindle or otherwise shaped to prevent the yarn being drawn off the spindle
blade and point when the carriage is running out.
In the accompanying sheet of drawings
Fig. 1 is a view of a mule spindle to which our improvement is applied and
Figs. 2 and 3 show the end of the spindle on an enlarged scale, in two positions
in order to illustrate the object of the inventioni more clearly.
In the drawings a is the upper portion or blade of a spindle, near the top of
which is cut a groove b preferably corresponding to the path of the yarn c on the
spindle blade as shown clearly in Figs. 2 and 3. The yarn c is coiled from the
cop nose (not shown) upward on the spindle blade and falls or is pulled into
the groove b between the cop nose and the spindle point, and the effect of this
groove is to hold the yarn during the outward run of the carriage and so prevent
it from being pulled or drawn off the point of the spindle during the outward
run as is liable to happen under ordinary conditions.
The lower edge of the notch or groove is bevelled off so as not to hold the yarn
or interfere with backing off.
Instead of the notch described a groove could be cut at any angle from near the
top of the spindle to a point below, or we could cut two grooves in opposite
directions so as to be able to spin with' spindles running in either direction for
weft or twist.
An important advantage attained by the use of our invention is that we are
enabled to set the spindles at a greater angle relatively to the vertical line without
any risk of the yarn slipping off the points of the spindles whereby we improve
the spinning and make better noses on the cops.
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:-
-
A mule or twiner spindle with a groove or grooves cut near its top substantially
as and for the purposes herein set forth.
