Improvements in Spindles used in the Preparation and Spinning of
Textile Fibres, and in the Lubrication of such Spindles.
I CHARLES BUTTERWORTH of 17, Queen's Road, Oldham, in the County of
Lancaster, Cotton Mill Manager, do hereby declare the nature of this invention to
be as follows:-
In
My said invention relates generally to spindles used in the preparation and
spinning of textile fibres, but is applicable particularly to the spindles of slubbing,
roving and intermediate frames. Such spindles are made solid and consequently, in
the larger sizes especially, they are of considerable weight' and require the
expenditure of more driving power than should be absolutely necessary.
addition to this the lubrication of such spindles is a constant source of trouble
especially in the case of slubbing, roving and intermediate spindles, and in frames
generally, where there are lifting rails or moving collars or bearings. At present
the proper lubrication of the collars of spindles of this type depends entirely upon
the care of the attendant, and such lubrication at the best is to a large extent of a
perfunctory nature. The result is that the spindles become soon worn and run out
of truth.
To remedy these defects, I make the spindles hollow thus materially reducing
their weight and securing much lighter running of the frame with less expenditure
of driving power. To provide for the lubrication of such hollow spindles, I utilise
the interior of the spindle as a receptacle for lubricant and arrange means whereby
the lubricant is automatically allowed to reach the bearing, and thus the lubrication
is effected uninterruptedly and without troubling the attendant.
In making my improved hollow spindles I use weldless steel tubing of sufficient
thickness and weight. The upper end to carry the flyer, if such is used, is reduced
or shaped from the tube by any suitable means and the foot of the spindle may be
formed from the tube in a similar manner, or I may form the foot of the spindle, or
it might be both ends from an inserted or brazed or welded plug or plugs. My
improved hollow spindle might be hardened or tempered throughout its length.
do not, however, limit myself to any particular mode of producing such hollow
spindles. For example it might be possible to draw or produce tubes with solid
blanks at the proper intervals from which the ends might be formed.
Such hollow spindles might be mounted and run in the same manner as ordináry
spindles and be lubricated in the usual fashion, but I prefer as aforesaid to utilise
the interior of such hollow spindles as a chamber for lubricant. The lubricant may
be introduced at the top of the spindle or through a hole in the side of the spindle and
situated beneath the shoulder of the flyer or in any other suitable position. The oil,
if such should be the lubricant, might be introduced into the hollow spindle through.
the inlet hole by means of a syringe or small portable pump. I also make a small
perforation in the spindle at the sliding collar bearing, and in such a position that
the said small lubricating perforation shall never be uncovered by the collar. The.
oil is raised by the centrifugal action of the revolving spindle and escapes through
the small perforation so as to lubricate the collar bearing. Thus the collar bearing
is automatically and uninterruptedly lubricated without troubling the attendant.
Similar means might if desired be employed to lubricate the foot step. Instead of
liquid lubricant, I might fill the interior of the spindle with solid lubricant the heat

perforations to the bearings.
I might even divide the hollow spindle into an upper and lower chamber, filling
the upper chamber with liquid lubricant to lubricate the collar bearing and the
lower chamber with solid lubricant to lubricate the foot or step of the spindle. In
conjunction with the solid lubricant I might use feeding means to regulate the
supply.

Improvements in Spindles used in the Preparation and Spinning of
Textile Fibres, and in the Lubrication of such Spindles.
I CHARLES BUTTERWORTH of 17 Queen's Road, Oldham, in the County of
Lancaster, Cotton 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 and accompanying drawings:-
My said invention relates generally to spindles used in the preparation and
spinning of textile fibres and for other cognate purposes, but is applicable
particularly to the spindles of slubbing, roving and intermediate frames. Such
spindles are made solid and consequently, in the larger sizes especially, they are
of considerable weight and require the expenditure of more driving power than
should be absolutely necessary. In addition to this the lubrication of such spindles
is a constant source of trouble especially in the case of slubbing, roving and
intermediate spindles, and in frames generally where there are lifting rails or
moving collars or bearings. At present the proper lubrication of the collars of
spindles of this type depends entirely upon the care of the attendant, and such
lubrication at the best is to a large extent of a perfunctory nature.
that the spindles become soon worn and ran out of truth.
The result is
To remedy these defects I make the spindles hollow, thus materially reducing
their weight and securing much lighter running of the frame with less expenditure
of driving power.
To provide for the lubrication of such hollow spindles, I utilise
the interior of the spindle as a receptacle for lubricant and arrange means whereby
the lubricant is automatically allowed to reach the bearing, and thus the
lubrication is effected uninterruptedly and without troubling the attendant.
Although my invention will be apparent to those making or using spindles,
without illustration, I have preferred to add hereto a sheet of drawings to which
I will hereinafter refer.
Fig. 1 is a vertical section of my improved hollow spindle a portion of the length
being removed for want of space.
Fig. 2 shows an improved mode of applying the flyer to such hollow spindles.
Fig. 3 is an improved form of footstep.
In making my improved hollow spindle a I use weldless steel tubing or tubing of
any other suitable metal of sufficient thickness and weight. The upper end to
carry the flyer, if such is used may be reduced or shaped from the tube by any
suitable means, and the foot of the spindle may be formed from the tube in a
similar manner, but I prefer to form the top and foot of the spindle from inserted
or brazed or welded-in plugs bb. My improved hollow spindle might be hardened
or tempered throughout its length.
I do not, however, limit myself to any particular mode of producing such hollow
spindles. For example it might be possible to draw or produce tubes with solid
blanks at the proper intervals from which the ends bb might be formed.

page_text: Such hollow spindles might be mounted and run in the same manner as ordinary
spindles and he lubricated in the usual fashion, but I might also utilise the interior
of such hollow spindles as a chamber for lubricant. The lubricant may be
introduced at the top of the spindle when such is convenient or through a hole c in
the side of the spindle and situated beneath the shoulder of the flyer or in any
other suitable position. The oil, if such should be the lubricant, might be
introduced into the hollow spindle a through the inlet hole e by means of a syringe
or small portable pump. The inlet hole c could be closed by a plug or other
means.
I also make a very fine perforation d in the spindle at a point which is covered
by the sliding collar bearing, and in such a position that the said small lubricating
perforation d shall never be uncovered by the collar. The oil is filled up to about
the level of the inlet hole e, or if the oil level is beneath the hole d, I would
depend upon the centrifugal action of the revolving spindle to raise the oil until it
reached the small perforation & through which it would pass so as to lubricate the
collar bearing.
Thus the collar bearing is automatically and uninterruptedly lubricated without
troubling the attendant. Similar means might if desired be employed to lubricate
the foot step. Instead of liquid lubricant, I might fill the interior of the spindle
with solid lubricant the heat of the spindle liquefying it sufficiently to let it
percolate through the perforation or perforations to the bearings.
I might also divide the hollow spindle into an upper and lower chamber, filling
the upper chamber with liquid lubricant to lubricate the collar bearings at d and
the lower chamber with solid lubricant to lubricate the foot or step of the spindle
through a small perforation.
In conjunction with the solid lubricant 1 might use feeding means to regulate
the supply.
I might either apply the flyers to the solid top of the spindles in the usual
manner or I might reverse the usual mode of application and as in Fig. 2 have a
tapered prolongation from the boss of the flyer, which would fit the tapered
mouth of the hollow spindle.
A pin e driven through the hollow spindle constitutes a driver which takes into a
slot formed at the foot of the tapered portion f of the flyer so that the flyer is
caused to partake of the motion of the spindle.
The oil feed hole c could be so situated as to be covered and stopped by the
tapered part so that no plug would be necessary. The hollow spindle a might
also be run without a solid foot, in the foot step g as shown in Fig. 3. In this
case the footstep would require to be lubricated in the ordinary way. At present
when the ordinary spindle is raised, as in doffing for example, and drops again into
the foot step, the lubricant is displaced and splashed out so that considerable waste
occurs. In the hollow end foot step shown, the oil displaced would be splashed
only into the interior of the spindle and would descend again.
The cone in the centre of the foot step acts as a guide to centre the spindle
properly.
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 [
claim is.
In the manufacture of spindles for slubbing roving and intermediate frames,
making the said spindles hollow, for the purposes and substantially as herein before
described and illustrated.
