SPECIFICATION in pursuance of the conditions of the Letters Patent,' filed
by the said Peter Armand le Comte de Fontaine Moreau in the Great
Seal Patent Office on the 17th November 1854.
5 TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER
ARMAND le Cointe DE FONTAINE MOREAU, of 4, South Street, Finsbury,
London, and 39, Rue de l'Echiquier, Paris, Patent Agent, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of May, in the year of our Lord
One thousand eight hundred and fifty-four, in the seventeenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Peter Armand le Comte de Fontaine Moreau, Her special license that I,
the said Peter Armand le Comte de Fontaine Moreau, my executors, admi-
nistrators, and assigns, or such others as I, the said Peter Armand le Comte
de Fontaine Moreau, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 of "IMPROVE-
MENTS IN CONNECTING THE PERMANENT RAILS OF RAILWAYS," being a communi-
cation from a foreigner residing abroad, upon the condition (amongst others)
that I, the said Peter Armand le Comte de Fontaine Moreau, by an instrument
in writing under my hand and seal, 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 Oflice
within six calendar months next and immediately after the date of the said
Letters Patent.*
NOW KNOW YE, that I, the said Peter Armand le Comte de Fontaine
Moreau, do hereby declare the nature of the said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, reference being had to the
Drawings hereto annexed, and to the letters marked thereon, that is to say:
The Invention communicated to me consists in connecting the permanent
rails of railways, by adapting to one side of the joints an iron fish, and fixing
the same by means of a key.
The accompanying Drawings represent the new mechanical arrangements
which I employ.
Figure 1 represents an elevation of the general arrangements; Figure 2,
plan; Figure 3, section.
Figure 4, side of the cast-iron fish which is next to the chair.
Figure 5, side of the cast-iron fish which is next to the rail.
Figure 6, section of the cast-iron fish.
Figure 7, plan and section of the key.
The object proposed by this Invention is to obtain rigidity at the joints of the
rails, by fixing them in their chairs in such a manner that, without opposing

page_text: any obstacle to their expansion and contraction, they may have the rigidity of
a continuous rail from one end of the line of railway to the other.
To effect this, I employ in place of a wooden key a cast-iron fish, which is
kept in its place in the chair by an iron key, which is interposed between the
chair and the fish, as shewn in Figure 1.
The fish may vary in length. One side of the fish is made to fit exactly
against the rail, so as to press against and support it; the other side next to
the chair is grooved out, so as to allow the key, Figure 7, to fit in between it
and the chair. This groove is terminated at each extremity by a swelling, so
as to make the key when driven home to take a curved form, and thus prevent
its becoming loose. The key, Figure 7, is made of good wrought iron, a
little smaller at the point than at the head, so as to be able to enter easily and
wedge all up tightly. The iron at the head is sufficiently thick to admit of
a rectangular hole being made for the purpose of withdrawing the key when
necessary. This mode of connecting the joints of rails is applicable either to
single or double headed rails, and the only change necessary to put this
Invention into practice is to substitute the fish and iron key for the ordinary.
wooden key. The Invention may be applied either at the joint chairs only or
at the joint and intermediate chairs, in which case the fishes at the inter-
mediate chairs may be of smaller dimensions than those at the joints.
Having now described the nature of the said Invention communicated to
me, and the manner of carrying it into effect, I wish it to be understood that
I do not confine myself to the precise details herein laid down; but what I
claim as new, and intended to be protected by the herein-before in part recited
Letters Patent, is, the securing the joints of rails by means of an iron fish and
key, as herein-before described and referred to in the several Figures of the
Drawings.
In witness whereof, I, the said Peter Armand le Comte de Fontaine
Moreau, have hereunto set my hand and seal, this Seventeenth day of
November, in the year of our Lord One thousand eight hundred and
fifty-four.
