Improvements in Lubricating Wheels.
We, WILLIAM EDGAR WILLIAMS of Exchange Buildings, Cardiff, in the County
of Glamorgan, Colliery Proprietor and REES RODERICK of Pandy Cottages Hirwain
in the County of Glamorgan Colliery Manager, do hereby declare the nature of
this invention to be as follows:-
Our invention relates to improvements in lubricating wheels and. is applicable more
particularly to the wheels of colliery trams.
In carrying it into effect an annular space is cored out of the boss of the wheel.
This runs around the axle, leaving a sufficient thickness of metal between the cored
out space and the axle. This space is filled with lubricating grease.
Holes are
formed in the metal, so as to allow the grease to pass through from the annular space
to the axle. A comparatively large opening is made in the boss between the arms for
the purpose of admitting the grease into the annular space. A hinged flap or door,
kept close by a suitable spring is made to cover the opening.

Improvements in Lubricating Wheels.
We, WILLIAM EDGAR WILLIAMS, of Exchange Buildings, Cardiff, in the County
of Glamorgan, Colliery Proprietor, and REES RODERICK, of Pandy Cottages, Hirwain,
in the County of Glamorgan, Colliery 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:-
This invention relates to improvements in the construction of wheel-hubs for
lubrication purposes and is applicable more particularly to the hubs of the wheels of
colliery trams.
The following is a description of our invention, reference being had to the
accompanying sheet of drawings, in which :-
Figure 1 is a side elevation, and Figure 2 a central section of a wheel, shewing
hub constructed according to our invention.
Similar letters of reference, denoting different views of the same parts.
In carrying our invention into effect, an annular cavity a, is cored out of or other-
wise formed within and around the substance of the nave or hub b, of the wheel; a
mouth or entrance c to the said annular cavity a, being provided, (preferably, situated
between the spokes or arms of the wheel), for the purpose of admitting the lubricant.
Beneath this annular cavity a, sufficient substance is left to form a proper bearing for
the axle. The cavity itself is utilised to contain the lubricant, which latter is inserted
or fed-in through the mouth or entrance c, above referred to. Through the

page_text: substance d, at the bottom of the said annular cavity, at intervals, aro formed
holes f, for the purpose of conveying the lubricant from the cavity to the bearing
and axle.
A hinged flap, cover or lid g, normally held closed by a spring h, on top thereof, is
provided to keep the contents within and free from dust.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A wheel hub or nave having an annular cavity concentric with its axis, an inlet
hole or holes, covered by a lid, leading into the said cavity, and radial outlet holes
extending from the cavity to the surface of the bearing, substantially as and for the
purposes described.
2. In combination with the arms, and felly of a wheel, a hub or nave having an
annular cavity concentric with the axis thereof, an inlet hole to the said cavity covered
by a lid, and radial outlet holes extending from the said cavity to the surface of the
bearing, substantially as and for the purposes described.
