I FRANK MOORE of 15 Richard Street Cornwell Road Lambeth in the County of
Surrey Mechanic do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide a lubricating cap for axles and shafts and
especially for carriage and other wheel axles in and through which the oil or other
lubricating matter can be supplied to the bearing when required without necessitating
the removal of the caps as is usual.
To carry out this object I make this cap in any usual or convenient manner and in
the centre of the closed end of the cap or thereabouts I make a small aperture
preferably somewhat larger on the inner circle of the closed end than on the outer side
into which exactly fits a plug which plug is kept normally laid against its seat in the
aperture by a coiled or other spring inside the cap whereby the exit of any of the
lubricating matter from the cap is prevented but when a fresh supply of the lubricating
material is required the plug can be pressed inwards and the required material
introduced through this aperture.
Preferably the sides of the aperture are counter sunk or made sloping towards the
aperture on the inside of the cap thus assisting the plug to automatically close on the
aperture.

page_text: I, FRANK MOORE of 15 Richard Street Cornwall Road Lambeth in the county of
Surrey 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 :-
The object of this my invention is to provide a lubricating cap for axles and shafts
and especially for carriage and other wheel axles in and through which the oil or other
lubricating matter can be supplied to the bearing when required without necessitating
the removal of the cap as is usual.
In the accompanying drawing I have shewn a cap for axles and shafts fitted with
and constructed according to this my invention.
Figure 1 is an elevation of the outer face of the cap. Figure 2 is an elevation of
the inner face of the same. Figure 3 is a section of the same taken at a, b, in
Figure 2.
The cap "A" may be constructed and formed and fitted in any usual or convenient
manner having regard to the particular axle or shaft with which it is to be used and
in the centre or thereabouts of the closed end of this cap "A" I make a small
aperture "B" the walls whereof are preferably bevelled as shewn or that is to say the
aperture "B" is somewhat larger on the inner face of the closed end of the cap "A"
than on the outer face thereof.
•
A plug "D" is fitted to this aperture "B" which plug "D" is kept normally hard
against its seat in the aperture "B" by a coiled or other spring "E" mounted in any
convenient position preferably inside the cap "A." This spring "E" may be of any
description and I shew in the drawing a very suitable kind and style of spring wherein
a bar "F" is secured to the walls of the cap "A" in a sectoral manner round which
bar "F" are coiled the ends of the spring "E" and this spring "E" is attached to
or bears against the base of the plug "D" forcing the plug "D" close home to
its seat.
When a fresh supply of the oil or other lubricating matter is required the plug "D"
can be pressed inwards against the spring "E" and the lubricating matter in the
desired quantity can be introduced into the cap "A" through the aperture "B."
Then when the pressure is removed from the plug "D" the spring "E" forces the
same home to its seat immediately and thus this lubricating matter cannot escape and
to ensure that this plug "D" shall tightly close the aperture "B" I can very

page_text: conveniently make the same in manner as is shewn in the drawing wherein the base
or body of the plug "D" is formed of leather or other somewhat compressible
material and somewhat overlaps or extends beyond the walls of the aperture "B"
while a small disc of metal or other hard substance is secured in the centre of the
outer side of the same to receive the aforesaid pressure by which this plug is forced
inwards.
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 :-
"B"
In a lubricating cap for axles and shafts the combination of the aperture
with the plug "D" and the spring "E" substantially as and for the purpose
hereinbefore described and declared.
