PROVISIONAL SPECIFICATION.
An Improved Axle Cap.
I, WILLIAM THOMAS HERBERT of 1 Clarendon Road, Walthamstow Clerk to
an Engineer, do hereby declare the nature of this invention to be as follows:-
This invention refers to the brass or other caps screwed or otherwise attached to
the ends of axles-or axle-boxes.
In order to avoid the necessity of removing the cap to introduce oil, I drill and
tap or otherwise make a hole in the front or side of the cap, and I fit a plug of
metal into the hole either by screwing it in or otherwise, so that it can be easily
removed when oil has to be inserted. The plug would be about a quarter of an
inch in diameter or larger and would have a recess formed in its face to receive a
key, or a thumb-bit or eye attached thereto for convenience in unscrewing or with-
drawing. The plug may be attached to a chain or to a cross-bar inside the cap so
that it can be sufficiently withdrawn for oiling but cannot be entirely separated from
the cap.

COMPLETE SPECIFICATION.
An Improved Axle Cap.
I, WILLIAM THOMAS HERBERT of 1 Clarendon Road, Walthamstow, Clerk to
an 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 is designed to effect the oiling of axles without the troublesome
operation of unscrewing the cap as is now necessary.
It refers to the metal caps screwed or otherwise attached to the ends of axles or
axle-boxes of vehicles.
In order to avoid the necessity of removing the cap to introduce oil, I drill and
tap or otherwise make a hole in the front or side of the cap, and I fit a plug of
metal into the hole either by screwing it in or otherwise, so that it can be easily
removed when oil has to be inserted. The plug would be about a quarter of an
inch in diameter or larger and would have a recess formed in its face to receive a
key, or a thumb-bit or eye attached thereto for convenience in unscrewing or
withdrawing.
It may be
The plug would preferably be flush with the surface of the cap.
attached to a chain or to a crossbar or ring inside the cap so that it can be
sufficiently withdrawn for oiling but cannot be entirely separated from the cap.
I will now describe the invention with reference to the accompanying drawings
in which
Fig. 1 shows an axle cap with the oil plug fitted in the centre of the front of
the cap.
Fig. 2 shows an axle cap with the plug fitted out of the centre of the cap to suit
axles such as Collings' which project against the centre.
Fig. 3 is a side view of the cap showing that the plug is flush with the surface of
the cap.
Fig. 4 shows a section of the cap with the plug in position and chain attach-
ment.
D

page_text: Fig. 5 shows the plug with its chain and ring or bar detached from the cap.
a, is the cap. b, is the plug. c, is the chain. d, is the ring or bar.
It will be understood that with the aid of my invention the axle can be oiled
without removing the cap.
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
The combination of an axle cap with an oil plug and with or without a chain
and ring or bar, or other device for preventing the plug being lost, as herein
described and set forth.
