Iм- PROVEMENTS IN RAILWAY AND OTHER WHEELS
Year: 1870

page_text: LETTERS PATENT to William Owen, of No. 47, Wind Street,
Aberdare, in the County of Glamorgan, for the Invention of “Iм-
PROVEMENTS IN RAILWAY AND OTHER WHEELS."
Sealed the 6th September 1870, and dated the 19th July 1870.
PROVISIONAL SPECIFICATION left by the said William Owen at the
Office of the Commissioners of Patents, with his Petition, on the
19th July 1870.
I, WILLIAM OWEN, of No. 47, Wind Street, Aberdare, in the County
of Glamorgan, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN RAILWAY AND OTHER WHEELS," to be as follows:-
The object of this Invention is to provide car and other wheels which
run loose upon their axles with oil chambers arranged to deliver the
oil upon the axles while running, but to withhold it while standing,
and in which the oil will be retained without plugs or stoppers. For
this purpose I form, by casting or otherwise, one or more cylindrical oil
chambers on the exterior of the hub of the wheel parallel with the bore. -
At one end of each oil chamber a central opening is formed to admit
of pouring in oil, and this opening is by preference surrounded with

page_text: an internal flange. From the bore or central hole for the axle a tube
passes into the interior of the chamber near to or beyond its central axis
so that while the wheel is standing, and if the chamber is only about
half. filled with oil, no oil will pass out through tube in whatever
position the chamber may be, whether it be above or below the axle.
To the interior of each chamber a lip or scoop is also fixed, which, when
the wheel revolves, and consequently, when the oil chamber is being
carried around the axle, delivers a small portion of oil at each revolution
of the wheel to the tube, and it passes down through the tube to the
axle. Or in place of the tube and lip or scoop a diaphragm may be
placed across the oil chamber near its end, and an opening formed
through the diaphragm at the outer side of the oil chamber, so that at
each revolution of the wheel oil may flow through the opening and
pass down at the back of the diaphragm to the axle.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Owen in the Great Seal Patent Office
on the 18th January 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
OWEN, of 47, Wind Street, Aberdare, in the County of Glamorgan, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of July, in the year of
our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Owen, Her special licence,
that I, the said William Owen, my executors, administrators, and
assigns, or such others as I; the said William Owen, my executors,
administrators, 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 RAILWAY AND OTHER WHEELS," upon the condition (amongst others)
that I, the said William Owen, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and

page_text: seals, 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.
NOW KNOW YE, that I, the said William Owen, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
The object of this Invention is to provide car and other wheels which
run loose upon
their axles with oil chambers arranged to deliver the oil
upon the axles while running, but to withhold it while standing, and in
which the oil will be retained without plugs or stoppers: For this
purpose I form, by casting or otherwise, one or more cylindrical oil
chambers on the exterior of the hub of the wheel parallel with the bore.
At one end. of each oil chamber a central opening is formed to admit of
pouring in oil, and this opening is by preference surrounded with an
internál flange. From the bore or central hole for the axle a tube
passes into the interior of the chamber near to or beyond its central
axis, so that while the wheel is standing and if the chamber is only
about half filled with oil no oil will pass out through the tube in
whatever position the chamber may be, whether it be above or below
the axle. To the interior of each chamber a lip or scoop is also fixed,
which when the wheel revolves, and consequently when the oil chamber
is being carried around the axle, delivers a small portion of oil at each
revolution of the wheel to the tube, and it passes down through the tube
to the axle. Or in place of the tube and lip or scoop a diaphragm may
be placed across the oil chamber near its end, and an opening formed
through the diaphragm at the outer side of the oil chamber, so that at
each revolution of the wheel oil may flow through the opening and
pass down at the back of the diaphragm to the axle.

Having thus described the nature of my Invention, I will proceed
to describe more fully the manner of performing the same.

page_text: ...
In these Figures a is the oil chamber; ba central opening at one end
thereof to admit of the chamber being supplied with oil. c is an internal
flange placed around the opening 6 in order to prevent the escape of oil
through this opening; or in place of this internal flange the end of the
chamber may be dished inwards in the manner shown at Figure 6. dis
a tube passing from the bore or central hole e for the axle into the
interior of the oil chamber a. f is a lip or scoop, which at each revolution
of the wheel takes a small portion of oil and delivers it into the tube d.
A single lip feeder may be employed, as shewn in the sections Figures 2
and 3, or the feeder may be a double lip feeder, as shewn in the section
Figure 4.
Figure 5 shews a side elevation of a wheel having combined with it two
oil chambers, each having a diaphragm g placed across it near its end in
place of the tube d and lip feeders f. Figure 6 shews a vertical trans-
verse section taken through the line x, x, Figure 5. Through the
diaphragm g of each oil chamber an opening his formed close up to
the side of the chamber which is furthest from the bore or central hole e.
When the oil chambers are below the axle oil will flow through the
openings h, and when as the wheel is revolving the oil chambers come
uppermost the oil will pass down the space k at the back of the
diaphragm and be delivered to the axle. When the wheel is standing
no oil will pass from the oil chamber to the axle in whatever position
the oil vessel may be. The oil chambers may either be cast together
with the wheel, or they may be formed separately and suitably attached
to it.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that what I claim
is, the combining with a railway or other wheel running loosely on
its axle one or more oil chambers arranged substantially as herein
described.
In witness whereof, I, the said William Owen, have hereunto set
my hand and seal, this Seventeenth day of September, in the
year of our Lord One thousand eight hundred and seventy.
W. OWEN. (L.S.)
