PROVISIONAL SPECIFICATION.
Improvements in Self-lubricating Axles and Bearings, especially
adapted for Colliery Trams.
I, ALBERT CHARLES ATTWOOD of 2 Agents Terrace, Pentrebach, near
Merthyr Tydfil, in the County of Glamorgan, Colliery Clerk, do hereby declare
the nature of this invention to be as follows
The object of this invention is to provide a simple cheap and efficient self-
Jubricating device for axles and which is of special value for colliery trams.
The axis is formed with a bored central recessed hole at each end deep enough
at least to reach the centres of the bearings, or passing right through the axle.
One or more passages are made from each bearing to the central hole which forms
the oil reservoir. The ends of same are fitted with screwed plugs provided with
flange fair with the outside of the axle and having a short central hole communi-
cating with the oil reservoir in the axle, and two slanting holes branching off
therefrom to the outside of the flange part. A cover put on with bayonet joint or
the like closes for the slanting holes. This cover has however a hole which when
brought fair with the one of the slanting holes which happens to be uppermost
allows of oil being supplied to the reservoir in the axle by means of a syringe or
spout can. Or the cover may be held on by a thin rim or flange parts bent or
spun over a corresponding rim or flange parts of the plug and be fixed in its closed
position by means of a central screw and nut. Horns or short handles are provided
on the cover for taking hold of it for conveniently turning it round as required.
The bearings are each formed with horns provided with inner vertical feathers or
grooves for the under block to be guided in. The latter may be of hard wood,
iron or other suitable material and its upper half round portion is made with a
recess for a sponge or porous pad to receive a small quantity of oil from the oil
hole each time it passes over it. The block is held in place by a bolt passing
through the horns or by a cotter.

Improvements in Self-lubricating Axles and Bearings, especially
adapted for Colliery Trams.
I, ALBERT CHARLES ATTWOOD of 2 Agents Terrace, Pentrebach, near
Merthyr Tydfil in the County of Glamorgan, Colliery Clerk, 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 this invention is to provide a simple cheap and efficient self-
lubricating device for axles and which is of special value for colliery trams.
Figure 1 of the accompanying drawings is a plan view partly in section and.
Figure 2 an end view of an axle for a colliery tram constructed according to this
The
invention. Figure 3 is a part sectional end view of a bearing for same.
axle A is formed with a bored central recessed hole B at each end deep enough at
least to reach the centres of the bearings C or as greatly preferred and shewn
here passing right through the axle. A piece of so called hydraulic pipe answers

therefrom to the outside of the flange part D'. A cover F put on with a bayonet-
joint or the like closes the slanting holes E. This cover has however a hole F¹
which when, as here shewn, brought fair with the one of the slanting holes E¹
which happens to be uppermost allows of oil being supplied to the reservoir in the
axle by means of a syringe or spout can. Or the cover may be held on by a thin
rim or flange parts bent or spun over a corresponding rim or flange parts of the
plug. The cover F may as shewn be fixed in its closed position by means of a
central screw G and nut. Horns F or short handles are provided on the cover for
taking hold of it for conveniently turning it round as required against stops D² on
the flange D'. The bearings H are each formed with horns H' provided with inner
vertical feathers or grooves H2 for the under block I to be guided in. The latter
may be of hard wood iron or other suitable material and its upper half round
portion is made with a recess 11 for a sponge or porous pad to receive a
small quantity of oil from the oil hole each time it passes over it. The block is
held in place by a bolt K passing through the horns or by a cotter and is kept
from dropping out by a piece of bent wire K' or by other suitable means.
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
J. claim is
1. An axle for colliery trams and other wheeled vehicles provided with oil
"reservoir consisting of an axial recess at each end or a hole right through with one
or more passages to the bearings the reservoir being closed at each end by a plug
with one or more passages diverging from the central oil reservoir and by a cover
movable on the plug and having a hole, through which oil can be supplied to
a diverging passage in its upper position when moved fair therewith substantially
as described and shewn.
2. An axle constructed as firstly claimed in combination with bearing blocks or
brasses having a recessed part for a pad or sponge which is intended to receive or
absorb a small portion of lubricating material as it is passed by the hole in the
axle which leads to the axial oil reservoir substantially as described and shewn.
Dated this 25th day of July 1894.
