PROVISIONAL SPECIFICATION left by the said James Murphy at the
Office of the Commissioners of Patents, with his Petition, on the
28th May 1873.
I, JAMES MURPHY, of Newport, in the County of Monmouth, Civil
Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF WHEELS AND AXLES," to be as
follows:-
-
I propose to make the axles of railway and any rolling stock with
flanges upon the axle at such a distance from the journal as would
be occupied by the inner boss of ordinary wheels when secured on the
axle.

page_text: and finally secure the whole together by bolting (or otherwise fastening)
through flanges, wheels, and washers.
I propose to secure the tyres upon wheels by means of two flat rings
of unequal breadth, dovetailing into the tyre, and bolted or riveted
together through the wheel.
In the case of metal wheels the washer D may be dispensed with.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 2
filed by the said James Murphy in the Great Seal Patent Office on

Letters Patent, bearing date the Twenty-eighth day of May, in the year
of our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said James Murphy, Her special licence that
I, the said James Murphy, my executors, administrators, and assigns, or
such others as I, the said James Murphy, 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 THE MANUFACTURE OF
WHEELS AND AXLES," upon the condition (amongst others) that I, the
said James Murphy, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and 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 James Murphy, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Sheet of Drawings
hereunto annexed and forming part of this my Specification, to tho
Figures drawn thereon, and to the letters of reference placed on the
Diagrams.
My improvements in the construction of wheels for engines and
vehicles used on railways, consist in making certain new and improved
forms of axles for railway and any rolling stock with flanges upon
the axle at such a distance from each journal as would be occupied
by the inner part of the boss of ordinary wheels when secured upon.
the axle.
Also in making certain new and improved forms of retaining rings
or tyre fastenings and fixing them in such a manner in combination
with the tyres and bodies of wheels as will firmly secure them together,
so as to prevent the tyre from leaving the body of the wheel in case of
fracture of the tyre.

page_text: In the case of metal wheels with spokes and an ordinary boss, or
made entirely of solid metal, the wheel after being bored and pressed
on the axle in the usual way is bolted to the axle flange C, no outside
washer plate being then necessary.
The advantages to be derived from this plan of constructing wheels
are the strengthening of the axle, whereby the frequent breakage of
axles immediately behind the boss of the wheels is prevented, also
securing the tyre from leaving the wheel in case of fracture.
I need scarcely observe that I do not confine myself to any particular
shape or dimension of axle flange O or washer D.
Having now described and ascertained the nature of my said In-
vention, and in what manner the same is or may be performed, I
claim as secured to me by the herein-before in part recited Letters
Patent,-
Firstly. The use, for the purposes herein-before set forth, of axles
flanged, substantially as herein-before described and illustrated on the
annexed Sheet of Drawing.
Secondly. The use of wheels having the tyre secured to the body of
the wheel by means of two flat rings dovetailed into the tyre, and bolted
and rivetted, or otherwise fastened together through the wheels, sub-
stantially as herein-before set forth and illustrated on the accompanying
Sheet of Drawing.
In witness whereof, I, the said James Murphy, have hereunto set
my hand and seal, this Twenty-fourth day of November, in
the year of our Lord One thousand eight hundred and seventy-
three.
