PROVISIONAL SPECIFICATION.
Improvements connected with Spindles and Bobbins for Ring and
Traveller Spinning and Doubling Frames.
I, THOMAS WRIGLEY of Waterside House, Todmorden in the County of
York, Mill Manager, do hereby declare the nature of this invention to be as
follows:-
--
My invention relates to spindles for ring and traveller spinning and doubling
frames and to specially constructed bobbins for use with the same, such spindles
having full or hollow conical seatings of such an inclination of their sides to the
spindle that the bobbins constructed to fit the said seatings with their undersides
cannot become jammed in or upon the same, but are rotated by the frictional
contact between said seatings and undersides caused by the gravity and shape of
the bobbin and construction and shape of the seatings, and consists in improve-
ments in the seatings and blades of said spindles and in the bobbins for the same.
I form grooves preferably in the surface of said conical seatings, or they may be
made in the bobbins, for the purpose of facilitating or promoting the expulsion of
air from between the seating and bobbin and causing the bobbin to adhere more
firmly to the seating. The depth of the grooves may be uniform or may increase
towards the edge of the seating or vice-versa, and as seen from above may be radial
or curved backwards or in the opposite direction to that in which the spindle is
rotated. The blades of the spindles fitted with such grooved conical seatings are
made cylindrical in those parts where the bobbin or a bush in the bobbin fits upon
then with a sliding fit and may be of the usual length, extending to or nearly to
the top of the bobbins, but preferably I use short blades extending only to about
the middle of the length of the bobbin, the top end of the spindle being made
cylindrical and the bobbin or a bush in the bobbin being bored so as to fit this part
with an easy sliding fit. This shortened spindle is much lighter and has its centre
of gravity lower than the ordinary spindle with long blade and may be used with
conical seatings without the grooves or with the grooves hereinbefore described, the
bobbins being held so truly central and firmly by such seatings that the spindle
blade may be shortened without impairing the steadiness of the bobbins when
running.

COMPLETE SPECIFICATION.
Improvements connected with Spindles and Bobbins for Ring and
Traveller Spinning and Doubling Frames,
I THOMAS WRIGLEY of Waterside House, Todmorden in the County of York,
Mill Manager, 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 :-
My invention relates to spindles for ring and traveller spinning and doubling
frames and to bobbins specially constructed for use with the same similar to those
described in my Specifications No. 4779 and 19206 A.D. 1890, such spindles having
full or hollow conical seatings of such an inclination of their sides to the spindles
that the bobbins constructed to fit said seatings with their undersides cannot become
17

page_text: jammed in or upon the same but are rotated by the frictional contact of said seatings
and undersides caused by the gravity and shape of the bobbin and construction and
shape of the spindle, and my invention consists in improvements in the seatings and
blades of said spindles and in the bobbin for the same.
On the sheet of drawings appended hereunto
Fig. 1. shows an improved spindle with full cone in elevation and bobbin in
. Bection,
Fig. 2 a plan of the same,
Fig. 3 a spindle with hollow cone and bobbin in section.
One of my improvements consists in forming grooves preferably in the surface of
said conical seatings, or they may be made in the bobbin, for the purpose of
facilitating or promoting the expulsion of air from between the seating and bobbin.
Figure 1 shows such a groove a in the full cone of the spindle c on one side and
a groove a¹ in the bobbin d on the other side, and Figure 3 a similar groove a in
the conical cup seating 6¹ on one side and a groove a in the bobbin d' on the other
side of the figure. The depth of the grooves may be uniform or may increase
towards the edge of the seating or vice versa, and as seen from above, the grooves
may be radial as shewn at I Fig. 2, or slanting backwards as shewn at II, or curved
backwards or in the opposite direction to that in which the spindle is rotated as
.shewn at III. The blades of the spindles fitted with such grooved conical seatings
or intended to be used with such grooved bobbins are preferably made cylindrical
in those parts where the bobbin or a bush in the same fits upon them with a sliding
fit, or they may be taper or partly taper and partly cylindrical, and may be of the
usual length extending to nearly the top of the bobbin similarly to those described
and illustrated in my Specifications hereinbefore referred to, but preferably I use
short spindles extending only to from one half to three quarters of the length of
the bobbin, and my further improvement consists in the arrangement of such short
blades for spindles having full or hollow conical seatings with or without grooves in
them or in the bobbins used with them.
This shortened spindle is shewn by Figs. 1 and 3. The upper part or blade c¹ of
the same is preferably made cylindrical as shewn on the drawings but may be
tapered or partly cylindrical and partly tapered, and the bobbin or a bush e in the
bobbin bored so as to fit this part of the spindle with an easy fit allowing the bobbin
to come fully down upon the seating. This shortened spindle is lighter and has its
centre of gravity lower than the ordinary spindle with a long blade, the bobbins
being held so truly central and firmly by such conical seatings with or without
grooves that the spindle blade may be shortened without impairing the steadiness
of the bobbins when running, while the reduced weight and lower centre of gravity
reduces the driving power required and increases the steadiness of the spindle when
running.
Having now. particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is―
Firstly. The arrangement or formation of grooves in the surfaces of full or
hollow conical seatings of spindles for ring and traveller spinning and doubling
frames or in the undersides of the bobbins fitting said seatings substantially as
hereinbefore described and illustrated by the drawings.
Secondly. The construction or arrangement of spindles for ring and traveller
spinning and doubling frames with full or hollow conical seatings having grooves in
the surfaces supporting and driving the bobbins by frictional contact with their
undersides, substantially as herein before described and illustrated.
Thirdly. The construction or arrangement of bobbins for ring and traveller
spinning and doubling frames with grooves full or hollow conical undersides for
fitting hollow or full conical seatings on the spindles, substantially as hereinbefore
described and illustrated...

page_text: Fourthly. The construction or formation of spindles for ring and traveller
spinning and doubling frames having hollow or full conical grooved or plain
seatings for the bobbins with short blades to said spindles extending only to from
one half to three quarters of the length of the bobbins, substantially as herein before
described and illustrated by the drawings.
