'. My Invention. consists, firstly, in a method of constructing and adapting the
bobbins used in ring and traveller frames, especially in those machines where the
bobbins are driven by the friction of the spindle blade; it is however applicable to
machines where the bobbin is driven positively. The bobbins I construct as tubes
(paper by preference), and on the spindle I attach rigidly the bushes or interior
bearings of the ordinary wood. bobbins. On theso I place a loose tube which fits
them, and is driven by one or both. The yarn is wound on this tube in the ordinary
manner. Or instead of making both of the above bushes or bearings rigidly
connected with the spindle, I only so connect the lower one, and the upper one then
becomes a part of the tube.
Secondly. My Invention relates to a method of obtaining a drag in "throstle"
frames, and especially in those machines in which a carrier is used between the bobbin
and the spindle blade, and consists in adopting a loose weight to the spindle, pressing
the bobbin or carrier downward, thereby producing an increased and more regular
friction, and this weight fits slackly on the spindle blade.

"IM-
ALFRED HIGGINS, of Salford, in the County of Lancaster, Machine Maker.
PROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING COTTON AND OTHER
FIBROUS MATERIALS."
My Invention consists, firstly, in a method of adapting and constructing the bobbins
used in "ring and traveller frames," especially in those machines when the bobbins
are driven by the friction of the spindle blade; it is however applicable to those
machines where the bobbin is driven positively.
One form of this part of my Invention is shewn at Fig. 1, in which 1 is the
spindle having fixed thereon two bosses 2, 3, answering to the bushes of the ordinary
wood bobbins, and upon these is placed the surface which constitutes the bobbin, and
which consists of a tube 4, of paper or other:such material, which can be rolled or
moulded. The bottom of the said tube in this case rests upon the braid 5, and for
doffing it is readily drawn off the fixed bosses 2, 3, and as readily re-adapted.
Instead of making both of the bosses shewn at 2, 3, fast with the spindle, the
lower one 3 only may be so adapted, the upper one 2 being in that case fixed to
the tube 4, and thus becoming a part thereof; or in place of these arrangements
the two bosses 2; 3, may be attached to and become a part of the paper (or other
such tube 4.
The above arrangements suppose the bobbin to be driven by friction, but it may
be driven positively by any suitable arrangement, as for instance, by a peg fixed to
the braid 5, and projecting through the tube 4 into the boss 3, as shewn by the dotted
lines 6, but in this instance the said tube must of course be formed with a notch at
its lower end as is well understood.
Fig. 2 shews a modification, the upper boss 2 being provided with saw gates or
other such cuttings away of its substance, and in any number as at 7, so that its
upper end may possess an elasticity for the more ready adaption of the tube 4, and
the same provision may be made in reference to the lower boss 3; and at 8 are loadings
of heavy material, such as lead, for acting 'by centrifugal force, whereby the pressure
of the boss 2 against the tube 4 may be 'increased.
Fig. 3 shews another modification, the upper boss 2 in this instance 'being provided
with two or more springs 9, which enable the bobbin to be readily adapted and keep
it connected with the boss 2.
Fig. 4 shews another modification; the top and bottom bosses 2, 3, are similar to
those shewn at Fig. 2, but the cup of the 'braid 5 is formed taper, so that when the
tube 4 is adapted it fits tightly therein.
Secondly. My Invention relates to throstles and consists in a method of obtaining
the "drag," and especially in those machines in which a carrier is used between the
bobbin and the spindle. This is shewn in one form at Fig. 5, in which 10 is a
carrier interposed between the bobbin 11 and spindle 12, such carrier being provided
with a flange which rests upon the copping plate 13, or upon flannel placed thereon.
This carrier at its lower end is provided with a flange 14. upon which is placed a
weight 15 fitting the spindle slackly, and which tends therefore to retard the rotation
of the carrier 10, and thus becomes an additional drag which may be modified.at
pleasure, but such drag need not necessarily be greater than usual.
The above describes the weight 15 as supported laterally by the spindle, but
it may be mounted upon the carrier by making the latter extend through it.
Fig. 6 shows a modification of this part of my Invention; in this instance the
carrier 10 extends upward, so that the top of the bobbin runs upon it as well as
the lower part thereof, and the weight 15 is hung on the carrier as before, but the
method of adapting the said weight may be varied in many ways.
Fig. 7 shews another modification, the carrier 10 and weight 15 being as before,

page_text: but the bobbin 11 is mounted upon a shell 16, the upper end of which bears against
the spindle, and the lower against the carrier.
The weight 15 as above described is free to revolve, but it may be prevented from
doing so by a wire attachment to the copping plate, as shewn by dots at 17 in Fig. 5,
such attachment being of sufficient elasticity to allow the said weight to act by
gravity, or projecting into a slot formed in the weight.
Instead of placing the weight as above described, it might be adapted in the
space between the spindle, and bobbin or shell, so as to rest on the top of the
carrier.
Having thus described and ascertained the nature of my said Invention and the
manner in which the same is to be performed, I desire it to be understood that I
claim as secured to me under the above in part recited Letters Patent, and for the
purposes above set forth,-
Firstly. The use of tubes of paper or other such material, which together with
bosses or bushes adapted to the spindle or to the said tubes in the methods described
constitute bobbins.
Secondly. The use of the weight illustrated at 15 for regulating the rotation of
the carrier.
In witness whereof, I, the said Alfred Higgins, have hereunto set my hand
and seal this Third day of December, in the year of our Lord One thousand
ALFRED HIGGINS. (L.s.)
