This Invention relates to that class of spinning machinery known as the
" American or Booth Sawyer" spinning throstle, and consists of an arrangement
whereby the spools can be instantaneously doffed from the spindles and replaced by
empty spools without the necessity of winding on a few turns by hand before com-
mencing the fresh spools as heretofore practised.
Instead of placing the wooden spool directly upon the spindle as usual we employ
an intervening shell or spool carrier made taper, and both shorter and of smaller
diameter than the spool itself. The latter fits upon the upper part of the spindle as
usual, and passes over the shell or spool carrier with its lower edge resting upon a
cylindrical collar or flange projecting from the bottom of the same, and which is
slightly concave on its circumference. As soon as the winding of the spools has
been completed the attendant lowers the guide rail so as to wind a few coils upon
this collar and then stops the machine. All that the attendant has now to do is to
break the threads between the collars and the finished spools and to remove the
latter and replace them with empty ones. He then raises the guide rail and imme-
diately puts the machine in motion without the necessity for winding the end of
each thread round its respective spool as hitherto practised, and by these means
about two-thirds of the time occupied in doffing the spools are saved, and hence a
great economy of time, labor, and expense is effected.

PROVEMENTS IN APPARATUS EMPLOYED IN MACHINERY FOR SPINNING COTTON OR
OTHER FIBROUS SUBSTANCES."
This Invention relates to that class of spinning machinery known as the
"American" or "Booth-Sawyer" spinning throstle, and consists of an arrangement
whereby the spools can be "doffed" from the spindles and replaced by empty spools
without the necessity of winding on a few turns by hand before commencing the
fresh spools as heretofore.
Such being the nature and object of our said Invention, we will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect, and in order that the samne may be clearly understood
we have annexed hereunto a Sheet of Drawings illustrative thereof, and have marked
the same with figures and letters of reference corresponding with those in the follow-
_ing explanation thereof.
Instead of placing the wooden spool a, a, Fig. 1, directly upon the spindle as
usual, we employ an intervening shell or spool carrier b, b, Fig. 2, made taper, and
both shorter and of smaller diameter than the spool a, a, itself.
The latter fits upon
the upper part of the spindle c, c, see Fig. 3, as usual, and passes over the shell or
spool b, b, with its lower edge resting upon a cylindrical collar or flange d, d,
projecting from the bottom of the same, and which is slightly concave on its circum-
ference, see Fig. 3, which shows the spindle c, c, supported by the collar e, e, fixed
in the bolster rail, the spool a, a, and spool carrier b, b, being shown in section.
As soon as
The upper parts of the spool and spool carrier fit on to the spindle c, c.
the winding of the spools has been completed the attendant lowers the guide rail so
as to wind a few coils upon the collar d, d, and then stops the machine. All that
the attendant has now to do is to break the thread between the collars d, d, and the
finished spools a, a, and to remove the latter and replace them with empty ones. He
then raises the guide rail to its original position and immediately puts the machine
in motion without the necessity for winding the end of each thread round its
respective spool as hitherto practised, and by these means about two-thirds of the
time occupied in doffing the spools are saved, and hence a great economy of time,
labor, and expense is effected.

Having now described the nature and object of our said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, we wish it be understood that we claim as our Invention the adaptation
to the spindle of the American
"
or Booth-Sawyer" spinning throstle of an in-
tervening shell or spool carrier between the spool and the spindle, the lower part of
such shell or spool carrier being furnished with a cylindrical collar or flange upon
which the lower edge of the spool rests, substantially in the manner and for the
purposes herein-before more particularly set forth.
In witness whereof, I, the said Walter Allen Whitaker (on behalf of myself
and the said Oswald Lawrence Whitaker, Janes Pearson, and Leonard
Entwistle) have hereunto set my hand and seal, this Third day of April,
in the year of our Lord One thousand eight hundred and seventy-seven.
