PROVISIONAL SPECIFICATION.
Improvements in Spindles for Winding and Drawing Machines used
Principally in the Manufacture of Silk.
ALFRED RIDGWAY Machinist Bank Street Macclesfield in the County of Chester do
hereby declare the nature of my invention for IMPROVEMENTS IN SPINDLES to be as
follows :-
The invention consists in employing a spring or springs made out of sheet steel or
other suitable material cut and shaped to form a series of springs parallell with the
centre part of the spindle or spindle proper.
The said sheet of steel being cut or
slotted so as to leave the ends intact to bend round the spindle thereby forming a
ferrule at each end of the spring or springs by which it is kept in position one end
or ferrule is left loose or made to fit easy on the spindle to allow it the requisite
amount of play in the working of the spring the springs by being thus made in one
piece act concentrically thereby keeping the spool or bobbin running true thereon as
by bending or deflecting any one of the springs, will cause the others to act
simultaneousely.
The said springs are bowed up in the centre to form a swell.
The spring may be secured at one end by driving on the friction lump or other-
wise as may be found suitable for the different purposes for which it may be
employed.

ALFRED RIDGWAY, Machinist Bank Works, Macclesfield in the County of Chester do
hereby declare the nature of my invention for IMPROVEMENTS IN SPINDLES, PRINCI-
PALLY USED IN THE MANUFACTURE OF SILK and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
The invention consists in employing a spring or springs made out of sheet steel
or other suitable material cut and shaped to form a series of springs parallel with the
centre part of the spindle or spindle proper. The said sheet of steel being cut or
slotted to form a series of bars or strips, running parallel with the centre bar or
spindle proper and slotted so as to leave the ends intact to bend round the bar
or centre part of the spindle thereby forming a ferrule at each end of the spring
by which it is kept in position one end or ferrule being left loose or made to fit easy
on the centre bar or spindle to allow it the requisite amount of play in the working
of the springs. The springs being thus made in one piece act concentrically thereby
keeping the spool or bobbin true thereon, as by bending or deflecting any one of the
springs will cause the others to act simultaneousely.
The springs are bowed up in the centre to form the requisite swell or spring.
The springs may be secured fast at one end by driving on the friction lump or
otherwise as may be found suitable for the different purposes for which it may be
employed.
The said springs may be made with one or more ferrules in. the middle of the
springs thus forming two or more bulbs or springs in the length of the spindle.

page_text: DESCRIPTION OF DRAWINGS.
Fig. 1 of the drawings anexed shows a general view of the spindle as used for
winding.
F2 shows the blank of sheet steel cut ready for bending round the spindle a Fig. 1.
The said spring is afterwards bowed up as shown at Figs. 1 and 3, (Fig. 3 being
a section through the spindle at Fig. 1.) to form a bulb or spring which will bend
or spring when pushed into the bobbin or pirn thereby holding the bobbin or pirn in
position thereon.
Fig. 2 also shows the spring cut and the ends and middle c left uncut which
bended round the spindle a Figs. 1 form ferrules which hold the spring in position.
The said spring may be held on the spindle by the friction lump & Fig. 1.
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 I claim is:
1. Making or forming a series of springs in one part or piece as and for the
purpose herein described.
2. The making or forming two or more series of springs in the length of the spindle
in one piece or part as and for the purpose herein described.
