Year: 1855

page_text: Sealed the 11th April 1856, and dated the 20th December 1855..
PROVISIONAL SPECIFICATION left by the said Evan Evans at the
Office of the Commissioners of Patents, with his Petition, on the
20th December 1855.
I, EVAN EVANS, of South Wales, do hereby declare the nature of the
Invention for "IMPROVEMENTS IN COMBINING AND FIXING RAILWAY BARS" to be
as follows:-
I
This Invention consists of using two forms of railway bars, in order that by
their combined use the bars of a railway may be better fixed and the whole
rendered more secure. For this purpose, what are called trough rails are
employed, together with other rails, each formed with a web or intermediate
part between the head and foot, or lower part of each rail. The hollow of
the trough rails and the webs and feet or lower parts of the other rails are
made to fit each. other, so that by removing the head or upper part of a rail it
may enter the end of the next trough rail and give support thereto, and these
parts may be fixed together by bolts and nuts, or otherwise, if desired. The
trough rails are fixed in like manner to what trough rails have heretofore been
fixed, and the other rails may be also similarly fixed, or only short lengths of
such other rails may be used between two trough rails.

filed by the said Evan Evans in the Great Seal Patent Office on the

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EVAN
EVANS, of South Wales, send greeting.--....
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of December, in the year of our Lord
One thousand eight hundred and fifty-five, in the nineteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Evan Evans, Her special licénce that I, the said Evan Evans,
my executors, administrators, and assigns, or such others as I, the said
Evan Evans, 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
COMBINING AND FIXING RAILWAY BARS," upon the condition (amongst others) that
I, the said Evan Evans, 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 Evan Evans, 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 state-
ment thereof, that is to say:-
This Invention consists of using two forms of railway bars, in order that by
their combined use the bars of a railway may be better fixed and the whole
rendered more secure. For this purpose, what are called trough or bridge rails
are employed, together with other rails; each formed with..a web or, interme-
diate part between the head and foot, or lower part of each ráil: The hollow
of the trough or bridge rails and the webs and feet or lower parts of the other
rails are made to fit each other; so that by removing the head or upper part
of a rail it may enter the end of the next trough rail and give support
thereto; and these parts may be fixed together by bolts or nuts; or otherwise, if
desired. The trough rails are fixed in like manner to what trough rails have
heretofore been fixed, and the other rails may be also similarly fixed, or only
short lengths of such other rails may be used between two trough rails.

page_text: Having thus stated the nature of my said Invention, I will proceed to
describe the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure shows an end view of the form of solid rail which I prefer to
employ; Figure 2 shows an end view of the form of hollow or trough rail which
I prefer to use. The sectional form, however, of the two classes of rails used
in carrying out my Invention may be varied, so long as the surfaces of the two
rails on which the wheels are to run correspond with each other, and the
stems or webs with the lower flange or foot of the solid rails is made to pass
into the hollow or trough rail. a is the solid rail; and b is the hollow or
trough rail, which is to be fixed to the longitudinal or other bearers of the rail-
way, as heretofore. Figure 3 shows a side view or elevation of a portion of a
railway constructed according to my Invention. This Figure shows two
portions of solid rails a, a, with a short length of a hollow or trough rail b
between them, and such hollow or trough rail is the means of fixing the three
parts to the longitudinal bearer c. I would state, that in place of having
short lengths of the trough rails b and longer lengths of the solid rails a, the
reverse may be the case, and long lengths of trough or hollow rails b be used
with short lengths of solid rails a, or comparatively long lengths of both
rails may be similarly combined. I would state, that the solid rails may, if
desired, be fixed at intervals to the longitudinal bearers, as well as the hollow
or trough rails b. In order to facilitate the taking out of a rail, a filling piece
D may be used, as shown at Figures 4, 5, 6, and 7, such filling piece being
fixed by a screw bolt E, or otherwise.
Having thus described the nature of my said Invention, and the manner of
performing the same, I would have it understood that I make no claim to the
use of solid rails separately, nor to the use of trough or hollow rails separately,
when constructing railways; but what I do claim is, the combined use of solid
and hollow rails in constructing railways, as herein described.
In witness whereof, I, the said Evan Evans, have hereunto set my hand
and seal, this Ninth day of June, in the year of our Lord One thousand
eight hundred and fifty-six.
