PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Preparing, Spinning, and Doubling
Cotton and other Fibrous Substances.
I JAMES WILLIAM BULLOCK of 128 Frog Lane Wigan in the County of
Lancaster, Book Keeper do hereby declare the nature of this invention to be as
follows:-
This invention relates principally to improvements upon the invention for which
I have made an application for Letters Patent No. 19053 dated November 27th
1889, the object of my present improvements being to simplify the construction
and improve the action of my apparatus as specified in the above named application
and also to render the same applicable to roving and similar frames.
In the first place instead of providing the shell which carries the bobbin with a
flange at the lower end resting on a flange on an inner fixed tube, I now fix at the
upper end of the fixed spindle a ring or flange of suitable thickness and diameter
upon which I place a cloth or other suitable washer and upon this washer the
closed end or top of the shell rests, and the requisite drag is thus applied to the
bobbins. The flange or ring above named is grooved round its periphery to receive
a split ring or similar device for preventing the bobbin shell from accidentally
being drawn off the end of the spindle when doffing.
The tube which extends upwards and forms part of the flyer is provided at its
upper end with an inwardly projecting flange so that the oil as it rises from the
oil cup is not allowed to Hy ontwards from the top of this tube but is directed
inwards and caused to descend again between the long collar or bolster upon which
the flyer revolves and an internal tube or shell, surrounding the spindle, the long
collar or bolster being rifled internally for that purpose or a space being otherwise
formed or left between the said collar or bolster and the internal tube or shell, and
openings being made in the long collar for the passage of this oil back to the
oil cup
I also place a small tubular washer encircling but not touching the lower end of
the flyer tube which runs in the oil cup so that the oil will not be thrown outwards
by the revolution of the said tube.
In some cases I prolong the internal tube or shell (or the holster itself) in a
downward direction below the bolster rail and I cause the pin or peg of the bobbin
shell to pass through the same, thereby itself forming the spindle, which in this
case will not be a fixed spindle but will revolve in a suitable footstep in the lifting
or spindle rail. In this case the drag may be given by an enlargement or flange
fixed to the spindle and resting on a washer on the spind'e rail, this enlargement
being also by preference so made as to form an oil cup into which the prolongation
of the bolster or tube dips at every traverse of the spindle rail and thus lubricates
the spindle. Or the spindle may rest on the flange instead of revolving in a
footstep.
The flyer may be made if preferred with ordinary inverted arms extending
upwards instead of being cup-shaped as described in my previous Specification
above referred to, or may have part of the said cup cut away or may be otherwise
similarly formed, to act as an inverted flyer.
I also propose to place the lifting rail of my apparatus above the bolster rail
after the manner of a ring spinning frame.
In this case also there will be no fixed spindle required but the flyer will still
revolve upon the long fixed tubular collar of the bolster and the peg of the bobbin
shell will be the only spindle required. The drag upon the bobbin shell may be
obtained as above described, or when the peg or spindle is a long one a disc may
DOJ1

page_text: be fixed at or near to the lower end of the revolving peg or spindle resting on a
suitable fixed washer (or even revolving in oil in a convenient chamber) or other
fixture attached to or forming part of the bolster or bolster rail.
A suitable ring is fixed to the lifting rail concentric with the axis of rotation of
the flyer which is, in this case, preferably in the form of a disc or shallow dish
provided with upwardly extending arms.
These arms rim in grooves notches or loops or between projections upon a louse
ring which is so formed as to slide very easily upon the fixed ring above named.
This loose ring is provided with a twirl or eye (or more than one twirl or eye)
fixed thereto.
The flyer arms drive the loose ring round upon the fixed ring and as the latter
rises and falls with the lifting rail the said arms must be sufficiently long to allow
of this notion. They may also be provided with curls at their upper ends so that
the yarn or thread may be wound once or twice round one of them before passing
to one of the eyes or twirls on the loose ring. The wharve may be made with a
cover shielding the oil cup.
Each of the flyer arms may be made donble, that is, with two wires or projections
one nearer the centre than the other so that when the thread passes from the inner
wire or arm to the twirl on the loose ring the outer arm will prevent "balooming
as the flyer revolves. The loose ring will be driven by the outer arm or wire.
"
In applying my invention to roving frames the flyer cup or dish carries upon it
an arched limb similar to the ordinary presser flyer and provided with the usual
presser arm but in frames where the lifting rail is above the bolster rail, as
hereinbefore described, the presser arm and its appertenences will be moved up
and down by the loose ring above named. In the roving frame the spindle will of
course be a driven spindle and not fixed.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Preparing, Spinning, and Doubling
Cotton and other Fibrous Substances.
I JAMES WILLIAM BULLOCK of 128 Frog Lane Wigan in the County of
Lancaster Book Keeper 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 relates principally to improvements upon the invention for which
Letters Patent No. 19053 dated November 27th 1889 were granted to me the
object of my present invention being to simplify the construction and improve the
action of my apparatus as described in the Specification of such Letters Patent
and also to render the same applicable to roving and other similar frames.
The nature of my said invention and the innumer in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the two sheets of drawings hereunto annexed and the following explanation
tliercof.
Fig. 1. on Sheet 1 of the drawings is a section of a spindle flyor and bobbin
illustrating the first part of my invention.
In the first place, instead of providing the shell a which carries the bobbin b
with a flange at the lower end resting on a flange on an inner fixed tube as
previously now fix at the upper end of the dead spindle a ring or flanged of
suitable thickness and diameter upon which I place a cloth or other suitable
washere and upon this washer the closed end or top of the shell a rests, and the
requisite drag is thus applied to the bobbin b.

page_text: The flange or ring is grooved round its periphery to receive a split ring for
similar device for preventing the bobbin shell a from being accidentally drawn off
the end of the spindle c when doffing. I also prefer to make an extra lift at a* at
the bottom of the shell a to wind a coil of the yarn onto previously to doffing.
The tube * which extends upwards and forms part of the cup-shaped flyer g is
provided at its upper end with an inwardly projecting flange so that the oil as it
rises from the oil cup is not allowed to fly outwards from the top of this tube, but
is directed inwards and caused to descend again between the long collar or bolster i
upon which the flyer revolves and an internal tube or shell k surrounding the
spindle c, the long collar or bolster i being rifled internally for that purpose, or a
space being otherwise formed or left between the said collar or bolster and the
internal tube or shell & and openings being made in the long collar i for the passage
of this oil back to the oil cup; I also place a small tubular washer / encircling
but not touching the lower end of the flyer tube g which runs in the oil cup h so
that the oil will not be thrown outwards by the revolution of the said tube.
In the modification shown in section at Fig. 2, the inner tube & is prolonged
downwards below the bolster rail and the spindle c is shown as a live spindle
running in a footstep m at the bottom, carried in the lifting or spindle rail, the
bobbin shell a is fixed on the top of the spindle c, thus forming part thereof, and
the drag is obtained by an enlargement or flange o fixed on the spindle c and
resting on a suitable washer or washers e placed on the lifting or spindle rail.
This enlargement if preferred may be made in the form of an oil cup as shown
at o into which the prolongation of the inner tube & dips at each traverse of the
spindle for lubrication.
In the modification shown at Fig. 3 the tube k is dispensed with and the bolster i
is prolonged downwards below the bolster rail, and in the modification shewn at
Fig. 4 the inner tube or shell k and the bolster i are both prolonged downwards
below the bolster rail.
In both these modifications the footstep m is preferably made in the form of an
oil cup and is provided with a cover m*; the oil rising from the cup / in these two
last modifications, descends between the spindle c and the bolster i (in Fig. 3) or
inner tube k (in Fig. 4) respectively into the oil cup m forming part of the footstep.
One or more passages p are made in the bolster i to allow a portion of the oil in
the oil cup m to flow back into the oil cup when the lifting rail is in its highest
position as shown on the drawings Figs. 3 and 4.
The drag may be obtained by the enlargement o resting on the washer or
washers e placed on the footstep at the bottom of the oil cup m.
The flyer instead of being cup-shaped may be made, if preferred, with ordinary
inverted arms extending upwards, or it may have part of the cup cut away or it
may be otherwise so formed as to act as an inverted flyer.

In applying my invention to roving slubbing or intermediate frames as illustrated
by Fig. 5 on the drawings the flyer cup g will carry upon it an arched limb
similar to an ordinary presser flyer and provided with the usual presser armı, part
of which is shown at r.
The spindle in this case will be a driven spindle and not a fixed one.
Having now 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 :-
First. The combination of the cup or inverted flyer having an inner tube running
upon the bolster tube with an internal flange formed at the top of the said
inner tube.
Secondly. The combination of the cup or inverted flyer, the inner tube with
internal flange at the top, and the drag washer inside the bobbin shell.
Thirdly. The combination of the cup or inverted flyer, the inner tube with
internal flange at the top, and the live spindle extending below the bolster, and
running in a suitable footstep m fixed in or resting on the spindle rail.

page_text: Fourthly. The prolongation downwards of the inner tube or spindle shell, or the
bolster, or both the inner tube and the bolster, below the bolster rail.
Fifthly. The combination of the arched limb with the top of the cup or inverted
flyer for roving slubbing and intermediate frames.
All constructed arranged and operating substantially as hereinbefore described 5
and illustrated by the drawings annexed.
Dated this 4th day of June 1891.
