Flint, North Wales, for the Invention of "IMPROVEMENTS IN SELF-
LUBRICATING WHEELS AND AXLES FOR CORVES OR TRAMS USED IN COAL AND
OTHER MINER
ADDT.TMÅ DE W MO OSVED Supraaur DHANISING LUBRICARIAN }}
Sealed the 21st May 1875, and dated the 14th January 1875.
PROVISIONAL SPECIFICATION left by the said Arnold Lupton at the
Office of the Commissioners of Patents, with his Petition, on the
14th January 1875.
I, ARNOLD LUPTON, of Bagillt, in the County of Flint, North Wales,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN SELF-LUBRICATING WHEELS AND AXLES FOR CORVES OR TRANS USED IN COAL
AND OTHER MINES, APPLICABLE TO OTHER Surfaces requIRING LUBRICATION," to be
as follows:-

page_text: The wheel is made of cast iron, steel, or other metal, and is hollow so
An
that it will hold a considerable quantity of oil or other lubricant.
aperture is made on one side or other convenient place closed with a
screw or other kind of plug, or a spring valve or other kind of valve.
Through this aperture the hollow of the wheel can be charged with oil, ||
and afterwards the aperture closed.
It is purposed that the wheel shall run loose on the axle; the wheel
boss to be bored and the axle turned to fit. The oil in the hollow of tho
wheel reaches the axle through a small hole bored through the boss,
and in this hole is placed a piece of iron or other wire or other suitablo
"needle," as in the "needle lubricator," and as the wheel revolves this
"needle" moves up and down, and so keeps the hole from being clogged,
and allows the oil to reach the axle. In order to facilitate the intro-
duction or removal of this "needle" it may be made supple, of twisted
wire, india-rubber, or other material, but this is not necessary, as it can be
introduced through a hole bored in the periphery of the wheel, which
hole is afterwards plugged up; or it may be introduced through a hole
in some other part of the wheel, also closed with a plug either screwed
or rivetted.
The Invention is also applicable to wheels which are fast on the axle.
In this case a hole is bored from the hollow part of the wheel through
the bars into the centre of the axle, and a hole is bored along the centre
of the axle, meeting the hole in the wheel, and a hole is also bored from
the outside of the axle in the middle of the bearing to the centre of the
axle meeting the hole on the centre of the axle. The hole bored along :
the centre of the axle is closed at the end by a screw or other suitable
plug, then the oil will run from the hollow wheel along the hole in the
axlc, and escape by the transverse hole on to the bearing. The hole in
the wheel is kept open by means of a "needle;" the hole along the
axlo is also kept open by a "needlo" rolling in it, and the short hole
across the axle is kept open by another "needle," either separato or
fastened to the "needle" along the axle.
The lubrication may be effected in other ways, ouc of which is by
boring two holes diagonally and putting a bent "needle" in; this
method is preferred for simplicity.
It is not necessary that the whole of the wheel should bo hollow, a
segment of the circle only can be made hollow, but it is preferred to
have it all hollow.

page_text: Important points in my Invention are the hollow wheel forming its-
own reservoir of oil or other lubricant, and as applied to coal trams, or
trams or corves used in mines other than coal mines, applicable however
to other purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Arnold Lupton in the Great Seal Patent Office.
on the 13th July 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ARNOLD
LUPTON, of Bagillt, in the County of Flint, North Wales, send:
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of January, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors, givo
and grant unto me, the said Arnold Lupton, Hor special licence that
I, the said Arnold Lupton, my executors, administrators, and assigns,
or such others as I, the said Arnold Lupton, my executors, admini-
strators, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN SELF-
LUBRICATING WHEELS AND AXLES FOR CORVES OR TRAMS USED IN COAL AND OTHER
MINES, APPLICABLE TO OTHER SURFACES REQUIRING LUBRICATION," upon the con-
dition (amongst others) that I, the said Arnold Lupton, my executors
or administrators, by an instrument in writing, under my, or their, or one
of their hands and scals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to
be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.

page_text: By Figure 2 of said Drawings is shewn a section of a wheel fast on
the axle, and the arrangements for lubrication which I prefer is as
herein-after described.

page_text: It is not necessary that the whole of the wheel be hollow, a segment
only can be made into a reservoir for oil, but it is preferred to make the
whole wheel into a reservoir.
The advantages in this Invention are a saving in oil or other lubricant,
and a constant and efficient lubrication; also a saving in the labour of t
lubrication, and simplicity and strength of design.
Having now particularly described and ascertained the nature of the
said Invention, and in what manner the same is to be performed or
carried out in practice, I hereby declare that I claim the herein-before
described Invention of "Improvements in Self-lubricating Wheels and 1
Axles for Corves or Trams used in Coal and other Mines, applicable to
other Surfaces requiring Lubrication," in which Invention the arrange-
ments constituting a hollow wheel, forming a reservoir for oil or other
lubricant for the lubrication of its own axle, for use in coal trams or
corves, or corves used in mines other than coal mines are peculiar and 1
important matters.
In witness whereof, I, the said Arnold Lupton, have hereunto set
my hand and seal, this Eighth day of July, in the year of our
Tawl One thousand night hundund and somente fira
Witness,
VALENTINE EYRE,
Bagillt,
