Improvements in Spindles for Spinning Machines.
I, CARL BITTER, of Rheydt, near Crefeld, Germany, Spinner, do hereby declare
the nature of this invention and in what manner the same 18 to be performed, to
be particularly described and ascertained in and by the following statement:-
My invention relates to improvements in spindles for spinning machines and
it has for its object to make these spindles fit for taking up the peculiai bobbins
used with the braiding machines, in order to be able to wind the yain upon these
bobbins direct on the spinning machine, so as to save the time and labour now
required for winding and unwinding the yain first on ordinary spinning machine
spindles and then from these, in one or even two intermediate operations, upon
other bobbins, until it is finally wound upon the braiding machine bobbins.
On the accompanying diawing I show the new spindle provided with the device
making it fit for taking up, the wide bored braiding machine bobbins, which
consists in the main in a spring or springs so aanged, that by then action the
bobbin can be stuck conveniently upon and taken off from the spindle and held
there exactly centrally and perpendicularly or parallel to the axis of the spindles
I use three forms of springs for carrying out my idea, they are shown in the
figures of the drawing.
Figure 1 shows the spindle provided with (four) flat curved spings without a
bobbin put thereon,
Figure 2 shows the same in a central vertical section with a bobbin fixed
thereon,
Figure 3 is an outside view of the same,
Figure 4 18 a horizontal section,
Figure 5 shows a spindle in vertical view with a modified form of spings,
Figure 6 is another variation, in which in place of flat springs, a thin strel
tube is used partly cut out at top and bottom and bulged out to form springs
Figure 7 shows the steel tube in detail
The spindle proper consists of a 1ound steel 10d A provided with the grooved
pulley B, which forms the lower part of a thimble of an acoin shaped boss Ę
A flange or cup D is placed 1ound this boss leaving an annular space between
it and the boss and in this space ale fixed, in the example shown 4 flat steel
springs F, which at their upper end are connected to a ring placed movably
upon the spindle A
The diameter of the flange D is exactly as wide as the
lower edge of the bobbin C stuck upon the spindle as will be seen from Figure 2
The springs Fare a little bent outwards so that the greatest distance from
the center of the spindle is somewhat larger than the radius of the bore of the
bobbin When then the bobbin is stuck upon the spindle, the springs in the
middle part spring inwards, the inner side of theu lower ends bearing upon
the circumference of the bush E, the outer side touching the inner circumference
of the hole in the bobbin and their upper part again springs outwardly, so that
they have a wavelike form, as seen in Figure 2, the upper wave bearing also
against the inner side of the hole in the bobbin, thereby steadying the same,
both at top and bottom, and so holding it securely perpendicularly and centrally
to the spindle, while at the same time the sharp edges of the springs prevent the
bobbin from turning round upon the spindle.
The variation shown in Figure 5 differs from the preceding one by the con-

page_text: struction of the springs and by this, that the boss E is cut away. The grooved
pulley B is here keyed duect upon the spindle A and the flange or cup D is cast
in one piece with the pulley In the annular space between the cup D¹ and the
spindle A I put upon the spindle movably a ring H, to which are fixed the
spings F, these here start from the ring H in an oblique duection upwards
and outwards to a distance of somewhat moie than 'the radius of the hole in the
bobbin, than they run parallel to the spindle to a length about equal to the
length of the bobbin and then they are bent inwardly again and go back again
to the spindle, where they are connected to a 11ng G₁ fixed to the spindle. A.
When a bobbin 18 now stuckiapon' the o constructed spindle the springs II
ale pressed inwardly, the ring H moves downwards a certain distance, then
the spings spring inwards at the bending points, the inwardly curved part of
the sping has now the tendency to press the corners outwards and so the
bobbin 18 held fast and perpendicularly upon the spindle
The thud form of my new, spindle is shown in Figure 6 The driving
pulley B and the flange part D are here of same construction as in the preceding
case, the flange part 1 is only shorter. In the annular space between the
pait D³ and the spindle I place upon the spindle A a tube K of nearly the same
diameter as the hole of the bobbin, at the upper end this tube is provided with a
hub or cover L being bored out centrally to allow the spindle A to pass through.
The cucumference of this tube 18 partly cut out at two parts of its length at M
and A, leaving only small strips al' and N' and these are bulged outwardly as
seen from the detail Figure 7, they act now like gpings and it will be easily
understood that a bobbin put upon a spindle provided with this tube will be held
in the same manner as by the springs shaped as, shown in Figures 2 and 5.
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 18:
1/ In a spinning machine spindle for duect winding of yain on braiding
machine bobbins on the spinning machine the combination of a spindle A, a
grooved pulley B, an acoin shaped boss E above said pulley with a cup or flange
shaped pait put 1ound said boss E, springs fixed in the annular space
between the boss E and the flange D, a ing & put movably on the upper part
of the spindle A and having the upper ends of the springs F fixed to it, the
whole as described and for the purpose set forth.
2/ In a spinning machine spindle for duect winding of yarn on braiding
machine bobbins on the spinning machine, the combination of a spindle A, a
grooved pulley B with a cup or flange shaped part D combined with said
pulley B, a ing G¹ fixed to the upper part of the spindle A, a ng H put
movably round the spindle A inside the cup D'; springs of the form shown
in l'igure 5 of the diawing and fixed to the rings G¹ and H, the whole as described
and illustrated and for the purpose set forth
3/ In a spinning machine spindle for direct winding of yarn on braiding
machine bobbins on the spinning machine, the combination of a spindle A, a
grooved pulley B³ with a cup D, a tube K placed round the spindle A in the
annula space between the cup and the spindle A, said tube K having bulged out
strips, toimed thereon, the whole as described and illustrated and for the
purpose set forth.
