"IMPROVEMENTS IN RING SPINNING FRAMES AND IN FINISHING AND ROVING
MACHINERY."
My improvements relate to the arrangement and combination of mechanical
parts in connection with apparatus for the spinning of wool and other fibrous
materials.
In the spinning of worsted and other yarns by means of the ordinary ring and
traveller, it is the common practice to traverse the ring rail for the purpose of
building up the yarn on to the bobbins or cops. This method has the disadvantage
of moving the ring and traveller in a vertical direction to and from the eye through
which the yarn passes after leaving the front rollers of the spinning frame, so that
the drag upon the yarn is continually varying or changing, so much so that the
yarn is built on to the bobbins by a continually varying amount of drag, too tight
in one part and too slack in another, and, in consequence the yarn is liable to.
strained or broken.
be
To remedy these defects I fix the ring rail to the spindle rail by means of pillars
of a proper length, so that the ring rail is stationary, and in combination with the
ring and traveller I use the ordinary tube and spindle, such as are used in cap
spinning. The tube rests upon the lifter plate in the usual manner, but the lifter
plate works between the spindle rail and the ring rail, holes being made in the
lifter plate for the pillars which support the ring rail to pass easily through.
In order to apply my Invention to finishing and roving frames I secure the ring
rail to the spindle rail, as before described, but in place of using cap tubes I cut a

on each of the spindles I place a washer and collar, which rest upon the lifter plate,
each collar has a key secured therein and will easily slide on the spindle, and at the
top of each collar I secure one or more pins which fit into corresponding holes
formed in the flange of the bobbin. When the machine is in motion the bobbins
will revolve at the same rate of speed as the spindles, and the lifter plate slide' up
and down the traverse, the ring plate remaining stationary.
The advantages of this arrangement are:-
First. That the drag upon the yarn in the spinning frame, finishing or roving
frames, is always equal, the angle between the eye through which the yarn passes
to the ring being always the same.
Second. There are no special bobbins required, as the bobbins used for fly or cap
spinning and this arrangement of ring spinning are all alike.
Third. The lifter motion which is used to build up the yarn on to the bobbins or
cops in fly or cap spinning frames requires no alteration by my improved method
of ring spinning, whereas, in the ordinary method of ring spinning, the lifter has to
work in an opposite direction.

GEORGE Salt, of the Firm of Sir Titus Salt, Baronet, Sons, and Company, of

"IMPROVEMENTS IN RING SPINNING FRAMES AND IN FINISHING AND ROVING
MACHINERY."
My improvements relate to the arrangement and combination of mechanical
parts in connection with apparatus for the spinning of wool and other fibrous
materials.
In the spinning of worsted and other yarns by means of the ordinary ring and
traveller it is the common practice to traverse the ring rail for the purpose of
building up the yarn on to the bobbins or cops. This method has the disadvantage
of moving the ring and traveller in a vertical direction to and from the eye through
which the yarn passes after leaving the front rollers of the spinning frame, so that
the drag upon the yarn is continually varying or changing, so much so that the
yarn is built on the bobbins by a continually varying amount of drag, too tight in
one part and too slack in another, and, in consequence, the yarn is liable to be
strained or broken.
To remedy these defects I fix the ring rail to the spindle rail by means of pillars
of a proper length, so that the ring rail is stationary, and in combination with the
ring and traveller I can use the ordinary tube and spindle, such as are used in cap
spinning. The tube rests upon the lifter plate in the usual manner, but the lifter
plate works between the spindle rail and the ring rail, holes being made in the
lifter plate for the pillars which support the ring rail to pass easily through.
Another method of applying my Invention to spinning frames, which can also
be applied to finishing and roving frames, is as follows:-I secure the ring rail to
the spindle rail, as before described, but in place of using short cap tube spindles I
use long spindles, in each of which I cut two longitudinal grooves or key ways
opposite to each other the whole length of the traverse; on each of the spindles I
place a washer and collar, which rests upon the lifter plate; each collar has keys
secured therein and will easily slide on the spindle, and at the top of each collar I
secure one or more pins, which fit into corresponding holes formed in the flange of
the bobbin. When the machine is in motion the bobbins will revolve at the same
rate of speed as the spindles, and the lifter plate slide up and down the traverse,
the ring plate remaining stationary.
The advantages of this arrangement are, first, that the drag upon the yarn in the
spinning frames, finishing or roving frames, is always equal, the angle between the
eyes through which the yarn passes to the ring being always the sane; second,
there are no special bobbins required, as the bobbins used for fly or cap spinning.
and this arrangement of ring spinning are all alike; third, the lifter motion which
is used to build up the yarn on to the bobbins or cops in fly or cap spinning frames
requires no alteration by my improved method of ring spinning, whereas, in the
ordinary method of ring spinning, the lifter has to work in an opposite direction.
Such being the nature and object of this my Invention, I will now proceed to.
describe the same more in detail, and in order that the same may be fully under-
stood I have annexed one Sheet of Drawings, which represent the front elevation
of such portions of a spinning frame and roving frame as are required to elucidate
my Invention.
Figure 1 represents the front elevation of such portions of a spinning frame as
are required to elucidate my Invention; Figure 2 shews my improvement as
applied to spinning frames with long spindles, which arrangement is also applicable
to finishing or roving frames; and Figure 3 are details of a spinning, roving, or

page_text: finishing spindle as arranged according to my Invention. In all the Figures,
similar letters represent similar parts.
The spindle rail is indicated by the letters A, in which the spindles B, B, are
fixed in the ordinary manner, and on which revolve and slide the cap tubes C, C;
on the cap tube are placed the bobbins D, D. which revolve at the same rate of
speed as the tubes C. The yarn which is being wound on to the bobbins is shewn
at E, E, and the lifter plato F, F, on whtch the tubes C rest is worked in a vertical
direction by the lifter spindles G, G, which are connected to the lifter the same as
in ordinary cap spinning frames. The ring rail H, H, to which the rings I, I, with
their travellers J, J, are fixed, is held rigid and stationary by the pillars K, K,
which are also secured to the spindle rail A. The eye rail or wire board L, L,
through which the yarn passes from the front rollers (not shewn in Drawings) to
the bobbins D, is ordinary. The step rail M, M, is used as a guide for the lifter
spindles G, G, to pass through and stay for the frame ends.
When applying my Invention to spinning frames fitted with long spindles and
for finishing and roving machinery I secure the ring rail H, H, as before described,
and the lifter plate F, F, is worked in the ordinary way, but I arrange the
spindles N, N, with two grooves or key ways P cut opposite to each other the
length of the traverse. On each spindle I place a washer Q which rests upon the
lifter plate F, F, and on each spindle resting on the said washers I place a collar R
having two keys which fit into the longitudinal grooves Pl; the pins S secured in
collar R fit into corresponding holes in the flange of the bobbin, so that the bobbins.
revolve at the same rate of speed as the spindles and travel through the stationary
ring rail as before described.
What I claim as my Invention is, the arrangement of fixing the ring rail to the
spindle rail by means of pillars or other equivalents so that the ring rail is
stationary, and using a seperate lifter plate for the purpose of building up the
yarn or roving on to the bobbins or cops instead of using the ring rail for that
purpose, as hitherto.
The use of the ordinary cap tube and spindle in combination with the ring and
traveller secured to stationary rail, substantially as hereinbefore described and
illustrated by the accompanying Drawings.
The arrangement of two grooves cut in the spindles, used in combination with
the collars and washers, substantially for the purpose hereinbefore described and
illustrated by the accompanying Drawings.
