PROVISIONAL SPECIFICATION.
Improvements in and connected with Spindles for Spinning Fibres.
I, IRA ICKRINGILL of Laurel Mount, Keighley, in the County of York, Spinner
do hereby declare the nature of this invention to be as follows:-
This invention has for its object the construction of spindles and the combination
of the same with certain portions of a spinning machine, in such a manner, that
short stapled fibre may be spun, with fewer breakages, and facilities afforded for
placing the bobbins or the like on the spindles, and the removal or "doffing" of the
same when full.
In spinning machines as hitherto constructed, the top of the spindles have, by the
construction and mounting of the said spindles, of necessity been at such a distance
from the front delivery rollers, as to allow the placing on, and removal of the
bobbins or the like, from the spindles and by the top of the spindles being at a
distance from the front delivery rollers greater than the length of the staple of fibre
under operation, frequent breakages of the yarn occur, resulting in a corresponding
number of piecings, therefore imperfect yarn.
I accomplish my object by mounting each spindle in a socket, in which is placed
a spiral spring, slightly compressed between a collar on the spindle and the bottom
of the socket.
A lifter plate for supporting and traversing the bobbins or the like on the
spindles, is mounted above the sockets, which are so placed that the ends of the
spindles are brought comparatively close to the "nip" of the front delivery rollers,
by which arrangement the fibre is twisted and a thread formed directly it is
delivered by the front rollers.
The yarn as it is spun, is built on the bobbin, tube, or cop, by the reciprocation
of the lifter rail, operated in any suitable manner, and when the bobbin or the
like is full of yarn, it is removed from the spindle, by drawing the spindle through
the socket away from the front delivery rollers, such a distance as to allow the
bobbin or the like to be removed, and another replaced; on liberating the spindle,
the before mentioned compressed spiral spring causes it to move back to its original
position, with the end near to the front delivery rollers.
Dated this 9th day of November 1893.

COMPLETE SPECIFICATION.
Improvements in and connected with Spindles for Spinning Fibres.
I, IRA ICKRINGILL, of Laurel Mount, Keighley, in the County of York, Spinner,
do hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention has for its object the arrangement of spindles and the combination
of the same with certain portions of a spinning machine in such a manner that,
short stapled fibre may be spun with fewer breakages; and to afford facilities for
placing the bobbins or the like on the spindles and the removal or "doffing" of
same when full of yarn.

page_text: In spinning machines as hitherto constructed, the top of the spindles have of
necessity been at such a distance from the front delivery rollers so as to allow the
placing on, and the removal of the bobbin or the like from the said spindles; and
by the top of the spindles being at a greater distance from the front delivery
rollers than the length of the staple of fibre under operation, frequent breakages
of the yarn occur, resulting in a corresponding number of piecings, therefore
imperfect yarn.
In describing my invention in detail reference is made to the accompanying sheet
of drawings representing sections of such portions of a spinning frame as are required
to illustrate how my invention may be carried into effect, and in which similar letters
represent similar parts where they appear.
A portion of each spindle S. is mounted in a socket suitably supported. In Fig. 1
the socket A. is shown mounted on two rails B. B. in section, which extend the
length of the machine. The bottom portion of the spindle at S' is preferably made
square and passed through a hole of similar section through the bottom portion
of said socket. A wharl W. is formed on the socket around which a band or
tape C. the band or tape passing over rotating cylinder D. also driven in the usual
manner.
By the spindle S. passing through the socket in the manner described, the former
is caused to rotate along with the socket.
Upon the spindle within the socket A. is a collar E. between which and the
bottom of socket is a spring F. slightly compressed, the spindle passing through the
lifter rail G. terminating with a flyer H.
By enclosing a spring F. in the manner described, the top of the spindles S. are
kept comparatively close to the "wire board" J. and nip of front rollers K. when
in their normal condition and during spinning, by which arrangement the fibre
is twisted and a thread formed directly it is delivered by the front rollers.
When utilizing spindles of the ordinary construction, they extend some distance
into a socket M. supported by a rail L. extending the length of the machine.
In each socket M. is mounted a foot step N. as in Fig. 2 or O. in Fig. 3. In
both cases the footstep is supported by a spiral spring F. and the spindles driven by
a band or tape C. combined with a tension pulley P. of the usual construction.
At the foot of spindles shown by Fig. 3 is a collar Q. grooved on the underside
for the reception of balls placed in a similar groove formed in footstep plate O. upon
which the respective spindles S. and balls rotate.
The yarn as it is spun is built on the bobbin R. tube or cop, as the case may be,
by the reciprocation of the lifter rail G. operated in any suitable manner, and when
the bobbin or the like is full of yarn it is removed from the spindles S. by pressing
the spindle in a downward direction away from the front rollers K. such a distance
as to allow the bobbin or the like to be removed and another replaced. On
liberating the spindle, the compressed spring F. expands and forces the spindle
back to its original and normal position ready for repeating the operation of
spinning.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,
In a spinning or like machine the supporting of a spindle by a spring in a manner
that the spindle may be moved vertically in its bearing for the purpose as herein-
before set forth.
