PROVEMENTS APPLICABLE TO MACHINES FOR SPINNING AND DOUBLING COTTON AND
OTHER FIBROUS MATERIALS."
Our Invention refers to those machines for spinning and doubling known as ring
and traveller frames, and consists,―
Firstly. In an adaptation to the bobbins, whereby fresh ends are connected
thereto after doffing. For this purpose we provide the bobbins with parts which
form a clip, into which the yarn passes when the bobbin is adapted to the spindle.
Thus we adapt to the lower part of the bobbin a piece or pieces of thin metal or
wire, between which and the surface of the bobbin the yarn passes as above
mentioned, and these two parts therefore hold it while the breakage for removing a
filled bobbin is effected, but leaving the end attached to the fresh bobbin.
In place of the above-mentioned arrangement the holding clip may be formed by
cutting notches in the bobbin itself.
Another part of our Invention relates to a method of casing the bobbin on the
spindle when it has to be doffed. For this purpose we use a blade or fork or other
such apparatus carried by the ring rail, which, when the bobbin has to be doffed,
is protruded inward beneath the said bobbin, and being then lifted by the rising of
the rail the bobbin is eased from the spindle; or with the same object we use a
blade independent of the ring rail, and which, as it is moved inward, is caused to
rise by means of inclines.

PROVEMENTS APPLICABLE TO MACHINES FOR SPINNING AND DOUBLING COTTON AND
OTHER FIBROUS MATERIALS."
Our Invention refers to those machines for spinning and doubling known as ring
and traveller frame, and consists,-
Firstly. In an adaptation to the bobbins, whereby fresh ends are connected
thereto after doffing.
Secondly. To a method of easing the bobbin on the spindle when it has to be
doffed.
The first part of our Invention is shewn in the elevation of a ring and traveller
bobbin at Fig. 1, and in plan view at Fig. 2.
At a is the bobbin constructed in the well-known manner, but at the lower end
thereof we form notches, as at b, 61, 62, 63, to be used as will be described by
reference to Fig. 5, which is a plan view of certain parts explaining how the end
is made fast to a fresh bobbin when the doffing has taken place. At c is a portion
of the ring rail; at d, the ring; and at e, the traveller, from which the thread f
passes to the filled bobbin g, which has been removed from the spindle h, and is
now held in the position shewn. This having been done by the left hand of the
attendant, the thread will, in its unbroken state; lie against or near to the spindle h,
and the attendant then, with the right hand, adapts a fresh bobbin, as shewn at a.
As this bobbin is pushed downward it arrives in contact with the thread f, and by
pressing it draws the ring e round, which motion traverses the said thread along the
bottom of the bobbin, and as there is a certain amount of tension thereon it passes
into one of the notches b, by which it is securely held, and the attendant then, by
breaking off the filled bobbing, leaves an end on the fresh bobbin, after which the
spinning may go on as usual.
The Drawing shews the bobbin provided with four notches, but the number may
be varied. When, however, there are four, the attendant should adjust the bobbin,
so that the said notches assume about the angle shewn in the Drawing, by which
means that shewn at 6 or 62 will be sure to receive the thread, and the adaptation
of these angles may be facilitated by colouring or otherwise marking one side of
the bobbin.
Figs. 3 and 4 represent a modification of this part of our Invention. In this
case the bottom of the bobbin a is provided with a ring of thin metal i, from
which there extend downward fingers k, l, k², k³, which press lightly upon or are
slightly free from the bottom part of the bobbin, and which fingers, when a fresh
bobbin is adapted, receive or catch as it were the thread, and act as a clip thereon
in the manner described in reference to Figs. 1, 2, and 5, excepting that in this
case the thread passes between the surface of the bobbin and a finger k, and upon
the same principle other arrangements of clips may be formed upon or adapted to
the bobbin ends.
The second part of our Invention is shewn in side elevation at Fig. 6, and in
cross section at Fig. 7, these two views representing portions of a ring and traveller
frame with our improvements adapted.
At l, m, are the two spindle rails, and at n the ring rail, on which the rings o
are mounted, the spindles being shewn at p, and a filled bobbin at q. The collars
of the spindles are at extending through a bar or plate 8, which by means of pro-
jections, as at t, rest upon the upper spindle rail l, and solid parts of this bar or
plates are therefore situate beneath the bottoms of the bobbins, as seen at a¹.
The bar or plates may extend across the whole length of the frame, or may be

page_text: adapted in several lengths, each one corresponding to a certain number of spindles.
At u is a rod connected by a link v to a lever w, capable of turning upon a centre x,
and mounted on this rod are hooks y situate within slots z formed in vertical bars 1,
which at their upper ends are turned over, as at 2, and there rest upon the spindle
rail between the projections t and bosses 3 of the collars r, by which two parts
of the said bars are therefore confined.
The use of the slots z is simply to facilitate the adaptation of the parts.
The bobbins having been filled, and it being required to ease them from the
spindles preparatory to doffing, the attendant turns the lever handle w upon its
centre x, by which means the rod u will be drawn forward, whereby the bars 1
will be turned as it were upon a centre, and a top corner thereof will be thrust
against the plate 8, thereby acting as an incline, and by elevating it will project it
against the bottoms a¹ of the bobbins, thus pushing then upward, and easing them
from their fit upon the spindles, after which they may be doffed and fresh bobbins
adapted, according to the first part of our Invention, or in any other manner.
Having thus described and ascertained the nature of our said Invention, and
the manner in which the same is to be performed, I desire it to be understood that
we claim as secured to us under the above in part recited Letters Patent and for
the purposes above set forth,-
Firstly. Providing the bottoms of the bobbins with nicks or clips, substantially
as described.
Secondly. The lifting rail illustrated at 8 acting substantially as described.
In witness whereof, I, the said Samuel Thornton, have hereunto set my hand
and seal, this Fifteenth day of January, in the year of our Lord One
thousand eight hundred and seventy-nine.
