Improvements in Apparatus for Ring Spinning, Doubling and
Twisting Machinery.
We, MARK LEACH, of Sunbridge Road, Bradford, in the County of York,
Machine Maker, JACQUES BRINDISI, of 24, Forster Square, Bradford, aforesaid,
Stuff Merchant, THOMAS WAIBLINGER BATEMAN, of 256, Swan Arcade, Bradford,
Manufacturer, and SAMUEL EDWARD ASQUITII, of 7 Grange Terrace, Allerton,
near Bradford, aforesaid, Mechanic do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in ring spinning machinery for
spinning doubling and twisting fibres and yarn, and its object is to increase the
speed of production as well as improve the quality of the yarn.
To carry out our invention we employ a rotary ring for each spindle fitted
with a loose traveller of suitable form. The rotary ring is mounted on a
stationary ring rail and the roving or its equivalent is preferably fed to the
traveller directly from the front roller without the intervention of a "top
board" or other guide. For this purpose the rollers are located nearer to the
top of the spindles than usual.
Any form of spindle and spindle bearing or bearings may be used that admits
of the spindle being "lifted" by a lifter motion to "build up" the yarn upon
the bobbin or its equivalent and a "button" or collar, preferably adjustable,
is fixed on the spindle to support the bobbin thereon.
The spindles may pass through bearings in a bearing rail below the ring rail
and may be supported in footstep bearings below fitted in a lifter rail operated
by a lifter motion.
"The rings may be formed with a cylindrical bearing piece or an annular groove
(which may be more or less vee shaped) above and below the driving wharles
and these cylindrical pieces or grooves bear against two pairs of anti-friction
discs, each pair of which is fixed upon a spindle mounted in suitable bearings
located in such a position behind and on opposite sides of the spinning spindle
that the band driving the ring draws the ring bearings against the said anti-
friction rollers and holds the ring concentric with the spindle.
Or we may mount the ring upon two uprights or their equivalent parallel to
the spindle and projecting from a disc or projection on a bearing sleeve fitting
the spindle and mounted in bearings in the top rail. In this case the above
mentioned ring rail is dispensed with: and the said uprights are approximately
as long as the longest bobbin.

page_text: The rings are driven at a suitably less speed than the spindles according to
the drag required.
An independent cylinder may be employed to drive the rings and this cylinder
may be driven from the cylinder driving the spindles by means of differential
gearing which may consist of conical pulleys connected by a belt capable of
being moved along the pulleys to alter the speed of the ring cylinder in relation
to the spindle cylinder.
As a modification the rings may be lifted instead of the spindles.

BRINDISI, of 24, Forster Square, Bradford, aforesaid, Merchant, THOMAS
WAIBLINGER BATEMAN, of 256, Swan Arcade, Bradford, Aforesaid, Manufacturer,
and SAMUEL EDWARD ASQUITH, of Grange Terrace Allerton near Bradford,
aforesaid, Mechanic 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 to improvements in ring spinning machinery for
spinning, doubling and twisting fibres and yarn, and its object is to increase the
speed of production as well as improve the quality of the yarn.

To carry out our invention we employ a rotary ring for each spindle fitted
with a loose traveller of suitable form. The rotary, ring is mounted on
stationary ring rail and the roving or its equivalent is preferably fed to the
traveller directly from the front roller without the intervention of a "top
board" or other guide. For this purpose the rollers are located nearer to the
top of the spindles than usual..
Any form of spindle and spindle bearing or bearings may be used that admits
of the spindle being "lifted" by a lifter motion to build up" the yarn upon
the bobbin or its equivalent and a "button" or collar preferably adjustable,
is fixed on the spindle to support the bobbin.
To fully describe our invention reference is made to the accompanying sheet
of drawings forming a part of this specification in which similar letters of
reference indicate corresponding parts in each of the figures.
Figure 1, represents a front elevation of such parts of a spinning frame as
are necessary to illustrate the application of our improvements, and Figure 2,
represents an end view of the same.
Figures 3 to 12, represent views of detail hereinafter referred to.
The frame A, the driving cylinder A2, the spindles A3, the roving bobbins A,
the back rollers A, the front rollers A, and the carriers A7 may be of anv
ordinary construction. But in order that the top guide board commonly employed
may be dispensed with the standards or bearers As supporting the roving bobbins,
drawing rollers and carriers are placed in a more vertical position than when

page_text: the usual top board is introduced between the front rollers and the spindles. In
this arrangement the yarn shown by the broken lines Y pasies directly from
between the "nip" of the rollers A to the travellers T without any intervening
guide or support.
The travellers T may be of any ordinary form and are loosely mounted so as to
freely move in the usual way round and upon the rings R, and for the purpose
of reducing the drag or strain upon the yarn which carries the travellers round
the rings rotary rings are employed.
Two arrangements for rotating or driving the rings are shown in figure 1
and in the detail figures, and we will first describe the arrangement shown in
figures 1 to 8.
The top spindle rail A is fitted with a hollow stud B for each spindle A
and the spindles pass through them. Figure 8, represents a cross sectional view of
the rail A diametrically through one of the studs B. A sleeve R is mounted upon
cach of the studs B and is provided with a driving wharle or pulley R3. Two
uprights R, R projecting from a disc or flange R on the top of the sleeve R
have the ring R fixed to them at the top concentric with the spindle.
Figure 7, represents a sectional view on a larger scale of the sleeves and
parts connected to it. The wharles R are driven at say from 15 to 40 per cent.
of the speed of the spindles A³ according to the extent it is desired to reduce the
drag, by hands Re from the cylinder C and this cylinder is driven from the
cylinder A by the strap C on the driving cones C and C. The step cones C
and Care provided in order that the relative speed of the two cylinders may
be varied to suit the different requirements of different classes of yarn and
different speeds of spinning.
The spindles A3 are fitted with wharles D and are driven in the usual manner
from the cylinder A. They are. mounted in footstep bearings 1 in the lift-r
plate or rail 1 and supported above by the said hollow studs. The lifter rail
is actuated by any suitable lifter motion to lower the spindles from the position
shown in figure 3 to that shown in figure 4 as the hobbins are filled. And the
bobbins are supported upon a collar or button on each spindle and are
driven by projections F3 on the upper face of the collars F2 engaging a notch
or notches formed in the underside of the bobbin.
Figure 5, represents a sectional view of figure 4 and Figure 6, a
of figure 3.1
plan view
Figure 9, represents a front view of a modified arrangement, Figure 10, a side
view and Figure 11, a plan view of the same.
The ring R is mounted upon two pairs of anti-friction rollers G, G and G, G.
In this case the ring is made with a plain cylindrical portion G on each side
of the wharle R³ to bear upon the peripheries of the anti-friction rollers and it
i kept against them and concentric with the spindle by the tension of the
driving band R. Shoulders G are provided immediately on each side of the
wharle R³ to confine the ring from vertical movement in relation to the anti-
friction rollers.
The anti-friction rollers are fixed upon spindles H mounted in bearings 113
which may be formed in the fixing H bolted to the top rail. Figure 12, repre-
sents a separate view of one pair of anti-friction rollers and their spindle.
It is obvious that a double frame may be constructed in a similar way, that
is to say: spindles may be fixed along both the front and the back of the frame.
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:
1. A machine of the type specified provided with rotary rings fitted with
loose travellers, substantially as herein shown and described and for the purpose
specified.
2. A ring spinning machine fitted with rotary rings R carried by one or more

page_text: uprights R projecting from the top of sleeves R2 mounted on hollow studs R
and provided with driving wharles K, substantially as herein shown and described
and illustrated.
