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, Mil Manager, do hereby declare the nature of this invention to 'be as
follows:-
:-
My invention relates to spindles and bobbins for ring and traveller spinning and
doubling frames and consists in forming the bobbin with a conical flange at the
bottom and fixing upon the spindle a conical cup into which the bobbin flange fits,
the angle of the cone being so large that the bobbin cannot become jammed fast in
the cup, but is rotated by frictional contact with said cup, and the bobbin or bushes
inserted into the bobbin being near to the upper and lower end of the same bored
out so as to fit the spindle or the sleeve and spindle loosely but without any per-
ceptible amount of side play. By this arrangement the bobbin, which may be a
double flanged bobbin or a pirn, is held centrally and steadied on the spindle
without being jammed as in the ordinary Rabbeth spindle and bobbin and can easily
be doffed and put on the spindles.

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 and bobbins for ring and traveller spinning and
doubling frames, and consists in forming the bobbin with a conical flange at the
bottom and fixing upon the spindle a conical cup into which the bobbin flange fits,
the angle of the cone being so large that the bobbin cannot become jammed fast in
the cup but is rotated by frictional contact with said cup, and the bobbin or bushes
inserted into the bobbin, being bored out near to the upper and lower end of the
same so as to fit the spindle or the sleeve and spindle loosely, but without any
perceptible amount of side play.
The manner of carrying out my invention is explained in the following statement
reference being had to the accompanying sheet of drawings.
In the said drawings
Figures 1, 2 and 3 are sectional elevations of bobbins and spindles formed
according to my said invention.
Figure 1 represents a spindle having a sleeveless "wharve," and cup carrying a
flanged bobbin.
The bobbin or 66
pirn" A is formed with a conical flange or base a, the incli-
nation of the conical face of the flange or base to the axis varying within a
workable margin of from about 30 to about 50 degrees. The bobbin or a bush
inserted therein is bored at or near to its extremities a² a³, to fit the spindle B
Figure 1, and sleeve c' Figures 2 and 3, loosely, the said spindle being preferably
turned parallel above the sleeve c¹ and having a reduced diameter at its upper

page_text: portion as shewn in each of the said figures. The cup C is preferably formed upon
the "wharve " c, the inclined wall of the said cup being of a corresponding angle
in the interior to that of the conical flange or base a of the bobbin. In Figures 2
and 3 the "wharve" is shewn deeply recessed from the underside and having an
extension upwards forming a sleeve c' which fits tightly the spindle in the manner
shewn. The exterior of the sleeve is fitted loosely into the bobbin, and in these
cases the bush at a³ may be omitted. The cup is preferably provided with air
holes which prevent the air in the bottom of the cup from cushioning and allow
the conical base to properly bed in the cup.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
Firstly. In ring and traveller spinning and doubling frames the employment of
bobbins formed with conical bases in combination with conically recessed cups fixed
to the spindle as and for the purposes hereinbefore described and illustrated in the
accompanying drawings.
Secondly. In ring and traveller spinning and doubling frames the combination
with the spindles thereof of conical cups carrying bobbins having bases coned to
fit said cups substantially as and for the purposes hereinbefore described and
illustrated in the drawings."
