WILLIE RAWSON, of 42 Alma Street, Halifax in the County of York Engineer
and JOHN JAMES ALLEN of 12 St. James's Street, Halifax, aforesaid Engineer, do
hereby declare the nature of this invention to be as follows
This invention relates to improvements in the construction of caps to be attached
to the bushes of the wheels of vehicles and also where wheels with caps on their
bushes are employed for other purposes.
Whereas under the present system it is the practice when a supply of oil is required
in the bushes of wheels to detatch the cap from the bush in order to recharge the cap
with oil, which involves the use of a spanner or key for the purpose of removing the
cap and when the cap is removed it has to be recharged with oil and replaced on the
bush. During the operation of replacing the cap on the bush a considerable amount
of oil is wasted.
This Invention consists of a small plug or screw inserted on the exterior face of
the cap which can easily be removed by hand without detatching the cap and the
required quantity of oil poured into the cap without waste and with a considerable
saving of time and labour.

Improvements in Caps for Bushes of Wheels of Vehicles and other
Purposes.
We WILLIE RAWSON of 42 Alma Street, Halifax, in the county of York, Engineer,
and JOHN JAMES ALLEN of 12 St James's Street, Halifax aforesaid, Engineer, 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 caps to be attached to
the bushes of the wheels of vehicles, and also where wheels with caps on their bushes,
are employed for other purposes.
Whereas under the present system it is the practice when a supply of oil is required
in the bushes of wheels, to detach the cap from the bush, in order to recharge the cap
with oil, which involves the use of a spanner or key, for the purpose of removing the
cap, and when the cap is removed, it has to be recharged with oil, and replaced on
the bush.
During the operation of replacing the cap on the bush, a considerable amount of oil
is wasted.
This invention consists of a small plug with spring, inserted in a cylinder which is
screwed into the cap, the face of the plug closing up an opening in the exterior face
of the cap, which can easily be pushed back by hand, or by the spout of the oil can,
to admit the lubricant without detaching the cap, and the required quantity of oil
can be poured into the cap without waste, and with a considerable saving of time
and labour; the cylinder is perforated to allow the lubricant to run through to
the axle.

means whilst lubricating.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
Constructing the caps of axle boxes, with external apertures for lubricating, so that
the axles can be lubricated without removing their caps, and the apertures
automatically closed, as and for the purposes shown and described.
