A TARDARDMENT IN RAILS FOR RAILWAYS
Year: 1867

page_text: LETTERS PATENT to William Frederick Henson, of New Cavendish
Street, in the County of Middlesex, Civil Engineer, for the Invention of
"A TARDARDMENT IN RAILS FOR RAILWAYS"
PROVISIONAL SPECIFICATION left by the said William Frederick Henson
at the Office of the Commissioners of Patents, with his Petition,
on the 21st May 1867.
I, WILLIAM FREDERICK HENSON, of New Cavendish Street, in the County
of Middlesex, Civil Engineer, do hereby declare the nature of the said
Invention for "AN IMPROVEMENT IN RAILS FOR RAILWAYS," to be as follows:-
My Invention consists in the construction and employment of double-
headed rails for railways with webs or flanges to the web of the rail, all as
hereafter described.
According to one arrangement I form double-headed rails for railways in a
piece with lateral or longitudinal webs or flanges on the web of the rail;.
these webs or flanges do not extend the whole length of the rail, but portions.
are omitted at intervals; the webs or flanges may be plane, double bevilled,,
or corrugated. To secure rails made in this manner to the sleepers I lay
them in sleepers with longitudinal grooves and pass bolts through the flanges
into the sleepers; the rails can be turned by removing the bolts.

page_text: According to another arrangement I form flanges or webs to the rails by
rivetting on each side of the web of the rail pieces of iron, and then securing
them in the sleepers as before described.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Frederick Henson in the Great Seal Patent Office on
the 21st November 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAN
FREDERICK HENSON, of New Cavendish Street, in the County of Middlesex,
Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of May, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William Frederick Henson, Her special licence that I, the said William
Frederick Henson, my executors, administrators, and assigns, or such others
as I, the said William Frederick Henson, 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 "AN IMPROVEMENT IN RAILS FOR RAILWAYS," upon the condition
(amongst others) that I, the said William Frederick Henson, 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 William Frederick Henson, 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 accompanying Drawings, that
is to say:
My Invention consists in the construction and employment of double-
headed rails for railways with webs or flanges to the web of the rail, all as
hereafter described.

page_text: According to one arrangement I form double-headed rails for railways in
a piece with lateral or longitudinal webs or flanges on the web of the rail;
these webs or flanges do not extend the whole length of the rail, but
portions are omitted at intervals; the webs or flanges may be plane,
double bevilled, or corrugated. To secure rails made in this manner to the
sleepers I lay them in sleepers with longitudinal grooves, and pass bolts
through the flanges into the sleepers; the rails can be turned by removing the
bolts.
According to another arrangement I form flanges or webs to the rails by
rivetting on each side of the web of the rail pieces of iron, and then securing
them in the sleepers as before described.
The accompanying Drawings illustrate the manner in which I prefer to
carry my Invention into effect.
Figure 1 is a plan, Figure 2 is a section, and Figure 3 is a side elevation
of the rail.
a, a, are the flanges on the web of the rail; b, b, are apertures through
which the bolts are passed to secure the rail to the sleepers. Where the
flanges a, a, are rivetted to the web the rail is secured by bolts to the sleeper,
as in the other arrangement.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim, the construction
and employment of rails for railways by forming in a piece with or attaching
to the web of rails of a flange or flanges, substantially in manner and for
the purpose herein-before described and illustrated in the accompanying
Drawings.
In witness whereof, I, the said William Frederick Henson, have here-
unto set my hand and seal, this Twenty-first day of November, in the
year of our Lord One thousand eight hundred and sixty-seven.
W.
T. HENSON.
