I, WILLIAM ALEXANDER CARLYLE, of Constitution Hill, Birmingham, Warwick-
shire, Electrician, do hereby declare the nature of this invention to be as follows :-
The object of my Invention is to render the spindles of polishing lathes and
other spindles, counter-shafts, carriage axles and the like self lubricating by con-
structing them as hereinafter described whereby each such article forms an oil
reservoir in itself and the use of separate lubricators and oil cups for lubricating
their bearings is dispensed with.
I will first describe my Invention as applied to spindles of polishing lathes.
According to this example of my Invention instead of making such spindles
solid as heretofore I make them hollow and form them each of a piece of steel or
other metal tube welded up at the ends and suitably turned, preferably taper from
the bearings to the ends, which latter are screwed in the ordinary manner for
attachment of the polishing or other bobs or brushes. In any convenient part of
the spindle and preferably between one of the bearings and projecting end I provide
a hole or holes by means of which lubricating material can be poured into the
interior of the spindle. The said hole or holes are suitably closed by a screw or
screws or other suitable means. At each of the bearings of the spindle I provide
another hole or holes by which the lubricating material can flow from the interior
of the spindle to the outside thereof so as to lubricate the bearings. I thus ensure
a constant supply of lubricating material to the bearings without that risk of
choking through dust as has heretofore been the case when separate lubricators
are used.
Instead of closing the ends of the tubular spindle by welding as above described
they may be closed by having a screwed or other plug inserted which plugs may
also forin the screwed ends to which the bobs or brushes are attached.
When applying my Invention to countershafts, carriage axles and other revolving
axles and the like I make each countershaft, axle or the like of a piece of tube
closed at the ends the interior forming a chamber for containing oil or other lubri-
cating material which passes on the bearings similarly as above described with
reference to a spindle of a polishing lathe.

I, WILLIAM ALEXANDER CARLYLE, of Constitution Hill, Birmingham, Warwick-
shire, Electrician, 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:-
The object of my Invention is to render the spindles of polishing lathes and
other spindles, countershafts, carriage axles and the like self lubricating by con-
structing them as hereinafter described whereby each such article forms an oil
reservoir in itself and the use of separate lubricators and oil cups for lubricating
their bearings is dispensed with.
I will first describe my Invention as applied to spindles of polishing lathes.
According to this example of my Invention instead of making such spindles
solid as heretofore I make them hollow and form them each of a piece of steel or
other metal tube welded up at the ends and suitably turned, preferably taper from
the bearings to the ends, which latter pre screwed in the ordinary manner for
attachment of the polishing or other bobs or brushes. In any convenient part of
the spindle and preferably between one of the bearings and projecting end I provide
a hole or holes by means of which lubricating material can be poured into the
interior of the spindle. The said hole or holes are suitably closed by a screw or
screws or other suitable means. At each of the bearings of the spindle I provide
another hole or holes by which the lubricating material can flow from the interior
of the spindle to the outside thereof so as to lubricate the bearings.
On the accompanying drawings Fig. 1 represents in plan a polishing lathe spindle
constructed according to my Invention; Fig. 2 is a sectional side elevation of the
same with the polishing lathe headstock shewn by dotted lines; Fig. 3 is a sectional
elevation and Fig. 4 is a plan of part of the same spindle separately and Figs. 5
and 6 are cross-sections of the same.
The same letters of reference indicate the same parts in Figs. 1, 2, 3, 4, 5 and 6.
A is the polishing lathe spindle made of a piece of steel or other metal tube
welded up at its ends a¹, a², which are screwed in the ordinary manner for attach-
ment of the polishing or other bobs or brushes. B is an ordinary headstock
provided with two bearings 61, 62, for the spindle to revolve in. c¹, c, are holes
through which oil or other lubricant can be poured into the interior a³ of the
spindle, the said holes being closed by the screws d¹, d², or by other suitable means.
At each bearing 61, 62, is a hole in the spindle which holes are marked e¹, e², through
which the lubricating material can flow from the interior of the spindle to the
outside thereof so as to lubricate the bearings. I thus ensure a constant supply of
lubricating material to the bearings without that risk of choking through dust as
has heretofore been the case when separate lubricators are used. In order that the
size of the holes e¹, e³, may be readily altered so as to allow a greater or smaller
quantity of lubricating material to flow to the bearings I make such holes in a plug f
which plugs are screwed into the spindle (see Figs. 3, 4 and 6) and can readily
be removed and other plugs having either smaller or larger holes substituted
therefor.

page_text: Instead of closing the ends of the tubular spindle by welding as above described
they may be closed by having a screwed or other plug inserted which plugs may
also forin the screwed ends to which the bobs or brushes are attached.
This modification of my Invention is illustrated by Fig. 7 which represents a
tubular polishing lathe spindle having its ends plugged up by the screwed plugs g², g³,
which form the screwed ends to which the bobs or brushes are attached.
When applying my Invention to countershafts, carriage axles and other revolving
axles and the like I make each countershaft, axle or the like of a piece of tube
closed at the ends the interior forming a chamber for containing oil or other
lubricating material which passes on the bearings similarly as above described with
reference to a spindle of a polishing lathe.
Fig. 8 represents in longitudinal section a countershaft constructed according to
my Invention consisting of a piece of tube h plugged or otherwise closed up at
each end so as to form an oil reservoir and provided with filling holes c and oil
holes e similar to the polishing spindles bereinbefore described and illustrated by
Figs. 1 to 7, both inclusive.
Fig. 9 represents in longitudinal section a railway carriage or waggon axle
constructed according to my Invention which is made tubular and plugged or
otherwise closed up at each end and provided with filling holes c by means of
which lubricating material can be poured into the interior and oil holes e through
which the lubricating material can flow from the interior on to the bearings.
Fig. 10 represents in part longitudinal section part of an axle for a carriage or
other road vehicle constructed according to my Invention. i is that part of the
axle on which the wheel revolves and j is the bush which is fitted in the nave of
the wheel. The part i is made tubular by having a hole a³ bored up from the end
to form an oil reservoir a filling hole c being drilled downwards from the upper
part of the collar and closed by a screw. e, e, are oil holes through which the oil
flows from the reservoir a³ to lubricate the bush 7.
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:
1st. The improvements in spindles of polishing lathes and other like revolving
spindles hereinbefore described with reference to Figs. 1, 2, 3, 4, 5, 6 and 7 of the
accompanying drawings, that is to say, making such spindles of tubular form closed
at the ends so as to form internally an oil reservoir and provided with an inlet and
outlet hole or inlet and outlet holes substantially as and for the purposes herein-
before described and illustrated by the accompanying drawings.
2nd. The improvements in countershafts, carriage axles and the like herein before
described with reference to Figs. 8 and 9 of the accompanying drawings, that is
to say, making such countershafts, carriage axles or the like of tubular form closed
at the ends so as to form internally an oil reservoir and provided with an inlet
and outlet hole or inlet and ontlet holes substantially as and for the purposes
herein before described and illustrated by the accompanying drawings.
3rd. The improvements in the axles of carriages and other road vehicles herein-
before described and illustrated by Fig. 10 of the accompanying drawings which
consists of making the ends of such axles of tubular form so as to form oil
reservoirs provided with inlet and outlet holes substantially as and for the purposes
herein before described and illustrated by the accompanying drawings.
