JAMES SEED, of Preston, in the County of Lancaster.
MACHINERY OR APPARATUS FOR SPINNING AND DOUBLING COTTON AND OTHER
FIBROUS SUBSTANCES." Partly a communication from abroad by Thomas Seed, of
Krahnholm, Narva, in the Empire of Russia
This Invention relates to the machine known as the "ring throstle" and other
continuous spinning and doubling machines to which the ring and traveller are
applicable, and which are used for spinning and doubling cotton and other fibrous
substances, and consists, firstly, in an improvement to assist the winding on of the
yarn or thread, more particularly on the bare spindle or on a tube, the external
diameter of which is the same size as the spindle, and at the nose of the cops, or
on bobbins or spools of smaller diameter than hitherto, which also automatically
regulates the tension on the yarn or thread, so that immediately on the yarn or
thread having any tendency to become unduly tight or overstrained, it causes the
traveller" to rotate quickly, thereby avoiding the breakage of the yarn or thread
and enabling much finer yarn to be spun.
The mechanism is so placed that it causes no inconvenience whilst doffing the
cops or bobbins. This is accomplished by placing concentrically in the annular
space between the cop or bobbin and the part known as the "ring," a tube to
which we give the name of "helper."
The said "helper" is caused to rotate by the spindle or otherwise.
The top of the said "helper" is placed so, and the diameter is such, that wher
the tension is too great on the yarn or thread, the traveller is brought mor

page_text: or less in contact with the external circumference of the. helper, whereby the
"traveller" is caused to rotate faster, thereby relieving the yarn or thread of the
excessive tension. In the place of a tube for the "helper" it may consist of a boss
having two or more legs or wires, at the top of which a short tube may be
fastened; or it may consist of a short tube with a wharve on it.
The "helper" may be driven by the spindle or separately, and at the same
rate as the spindle, or at another uniform rate. Friction discs or wheels may be
used to drive or steady the "helper."
In some cases the helper is caused to be brought out of action or less in action
when winding on the thicker-diameter of the cop or bobbin, -and this. is-effected by
suitable mechanism causing the "ring rail" and the rail holding the helper to
vary relatively to one another in their up and down motion. The upper part of
the "helper" may be made conical, and either notched, or fluted, or smooth.
Various mechanical modifications may be made in the details of construction
whereby the same result is effected, in all of which the "helper" is driven at
uniform rates by means situated below the traveller and is so placed as not to
interfere with the doffing.
In some cases it is preferable to use a "traveller" having a projection, round
which the yarn is passed and which may be brought more or less in contact with
the "helper." According to the-second-part-of-the Invention, the "ring," instead
of being stationary as heretofore, is caused by suitable means to revolve at the
same rate as the spindle, or at a different uniform or variable rate.
A "traveller" of suitable form is placed on the "ring" to which is applied a
constant or variable break, so actuated that it will cause the necessary winding on.
In most cases this arrangement requires the break or drag to be applied stronger
when winding on the smaller diameters, or less at the large diameters, being the
reverse to the ordinary "ring throstle."
99
A stationary "ring may also be used together with the rotating "ring," a
traveller of suitable form being placed on each, which travellers may be connected
together or otherwise.
A further modification consists in dividing or constructing the "ring" in two
parts, one part of which is caused to revolve round the other part which remains
stationary, the "traveller" is placed over the two parts.

"
This Invention relates to the machine known as the "ring throstle and 'other
continuous spinning and doubling machines to which the "ring and traveller" are
applicable, and which are used for spinning and doubling cotton and other fibrous
substances, and consists
First. In an improvement to. assist the winding on of the yarn or thread, more
particularly on the bare spindle or on a tube, the external diameter of which is
the same size as the ordinary spindle and at the nose of the cops or on bobbins, or
spools of smaller diameter than hitherto, which also automatically regulates the
tension on the yarn or thread, so that immediately on the yarn or thread having
any tendency to become unduly tight or overstrained, it causes the "" traveller
rotate more quickly, thereby avoiding the breakage of the yarn or thread, and
enabling much finer yarn to be spun. The mechanism is so placed that it causes
no inconvenience whilst doffing the cops or bobbins.

to
The second part of our Invention consists principally in causing the ring itself
to rotate and applying a break acting directly on the "traveller,' as hereinafter
described, for the purpose and advantages as described in the first part of our
Invention.
:
Such being the nature and object of the said Invention I 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 same may be clearly understood
I 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 following explanation thereof:-
According to the first part of the Invention we place concentrically in the
annular space between the cop or bobbin and the part known as the "ring," a tube
to which we give the name of "helper." The said "helper" is-caused to rotate by
the spindle or otherwise. The top of the said "helper" is placed so; and the
diameter is such, that when the tension is too great on the yarn or thread, the
traveller is brought more or less in contact with the external circumference of the
"helper," whereby the "traveller" is caused to rotate faster, thereby relieving the
yarn or thread of the excessive tension.
"
Fig. 1 in the annexed Drawing shows (partly in section) the application to a
rabbeth spindle" of the first of our Invention, a, a, being the 'spindle; b, b, the
long collar; c, c, the ring; and d, d, the "traveller."
In this modification (instead of a tube) the "helper" consists of a boss or ring
e, e, having two or more legs or wires f, f, at the top of which a short tube g, g,
is fastened; or it may consist of a short tube with a wharve on it. The
helper may be driven by the spindle by means of a disc g¹, (see Fig. 1), or it
may be driven separately and at the same rate as the spindle, or at another
uniform rate.
Fig. 2 shows a modification of the "Booth Sawyer" spindle; wherein the
'helper" g, g, is driven by means of a cup-shaped disc h, h, from the spindle; the
disc is formed with notches or slots through which the arms f, of the "helper"
pass, and the lower part of the "helper" is steadied by the long' collar 'b, b

page_text: ;
Fig. 3 shows a spindle specially constructed to be used in conjunction with the
"helper" g, g; the ring rail and the rail i, i, holding the "helper" are stationary.
A hollow stud is fixed in the rail i, i, having an oil cup k, k, in which the lower
end of the "helper" works. The helper is driven by the wharve 1, 1, which
drives the spindle a, a, through a dog m, m. By this plan the spindle may be
'made very short:
The spindle is supported by a long collar b, b, passing through the rail i, i, and
is moved up and down by a rail n n, below, to which the requisite motion is
given. Fig. 4 is a plan view of the ring traveller and "helper."
Friction discs.or wheels may be used to drive or steady the "helper." In some
cases the "helper" is caused to be brought out of action, or less in action, when
winding on the thicker diameter of the cop or bobbin, and this is effected by
suitable mechanism (such as cams, for instance), causing the "ring rail" and the
rail holding the helper to vary relatively to one another in their up and down
motion. The upper part of the "helper" may be made conical, and either notched,
or fluted, or smooth. In Fig. 5, four notches o, o, are cut out of the upper part of
the "helper," and in Figs. 6 and 7, two projections are formed to assist the action
of the helper on the "traveller."
Various mechanical modifications may be made in the details of construction,
whereby the same result is effected, in all of which the "helper" is driven at
uniform rates by means suitated below, the traveller, and is so placed as not to
interfere with the, doffing.
In some cases it is preferable to use a
traveller" having a projection round
which the yarn is passed, and which may be brought more or less in contact with
the "helper," as shown at Fig. 1.
According to the second part of the Invention, the " ring," instead of being
stationary as in the: ordinary "ring throstle," is caused by suitable means to revolve
at the same rate as the spindle or at a different uniform rate. A traveller of
suitable form is placed on the ring, to which is applied a constant or variable
break, causing the necessary winding on. In most cases the arrangement of
. variable break requires the break or drag to be applied stronger when winding on
the smaller diameters, and less at the larger diameters, being the reverse to the
ordinary. "ring 'throstle."
÷
Fig. 8 shows the revolving ring p, p, on which is placed our improved traveller
dd, which works against a break rim q, q. The lower part of the apparatus
which drives the ring is supported by a rail having an oil cup in it; this passes
up and down on a long collar b, b; the ring may be driven by any of the means
by which the helper" is driven. The traveller which we find most suitable
consists of two, loops through which the yarn or thread passes, as shown at plan
view, Fig. 9.: sly
The yarn or thread is deflected at a greater angle than by the ordinary
"traveller,giving the yarn greater power to pull the traveller more or less
from the breakır,r. Figs. 10 and 11 show the plan in which an ordinary
traveller may be used; part of the break rim is cut away (see Fig. 11) to admit
of the yarn.or thread being passed under the traveller in the ordinary way.
A: stationary ering may also be used together with the rotating ring," a
traveller of suitable form being placed on each, which travellers may be connected
- together or otherwise.
A further. modification consists in dividing or constructing the ring in two
parts, one: part. spis, of which (see Fig. 12) is caused to revolve round the other
part, t; t; which remains stationary; the "traveller" d, d, is placed over the two
parts.
to olbr
Fig. 13 shows a further modification of the revolving ring with the fixed break
rim, the traveller," being of the form shown.
Fig. 14-ista plan view and shows the revolving ring with fixed break rim r, r;
u, u, is a variable, break placed near each ring 7, r, which is moved more or less
in contact with the traveller as required by a selfacting arrangement; each of the

page_text: parts u, u, which move more or less in contact with the traveller, are attached to
a bar v, v; a lever is attached to this bar having the fulcrum on the rail, the other
end of which lever is pressed by a spring or other suitable means against an
incline, which is raised higher as the building of the cop or bobbin proceeds either
by the rail or other suitable mechanism; the variable break u, u, may have its
surface straight, curved, notched, or fluted, or smooth.
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, I wish it be understood that we claim as our Invention,-
First. The "helper" for assisting the winding on and the method of automatically
governing the tension of the thread by bringing the traveller more or less in
contact with the said "helper," substantially as shown and described.
Secondly. The revolving ring supporting a suitable traveller in combination
with a constant or variable break acting directly upon the traveller, substantially
as specified.
Thirdly. The combination of the revolving and stationary rings, substantially as
shown and described; and
Fourthly. We claim the combination therewith of a variable break, substantially
as hereinbefore specified.
In witness whereof, I, the said James Seed, have hereunto set my hand and
seal, this Seventh day of February, in the year of our Lord One thousand
