4, South Street, Finsbury, London, and 39, Rue de l'Echiquier, Paris,
Patent Agent, for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION
Sealed the 12th September 1854, and dated the 28th June 1854.
PROVISIONAL SPECIFICATION left by the said Peter Armand le Comte
.de Fontaine Moreau, at the Office of the Commissioners of Patents,
with his Petition, on the 28th June 1854.
I, PETER ARMAND le Comte DE FONTAINE MOREAU, of 4, South Street,
Finsbury, London, and 39, Rue de l'Echiquier, Paris, Patent Agent, do
hereby declare the nature of the Invention of "IMPROVEMENTS IN
CONSTRUCTION OF AXLE BOXES" to be as follows:-
ΤΗΣ
The Invention communicated to me consists in an improved mode of con-
structing axle boxes.
The accompanying Drawing is a plan of the mechanical arrangements. A,"
fusce; B, box; C, double supporters; D, nut; F, cap; G, orifice for the
introduction of oil; H, cap; I, J, & K, washers.
The box B, inclosed in the nave of the wheel, is of a truncated conical form,
its greatest width being in the interior of the vehicle. It is provided internally
at each of its extremities with projecting supporters G, on which the fusee of

page_text: the axle bears without touching the other parts of the box; between the two
supporters is a space for containing oil. The box outside of the vehicle is
closed with a cap, at the extremity of the fusee. To close the box at the
inner side behind the supporters, I set two washers I, J, one of leather, and
one of vulcanized caoutchouc, superposed, and behind them another leather
washer K; and, finally, a cast-iron cap, which is fixed to the box by means
of screws. This stuffing is in the interior of the box.
The barrel of the axle is provided with a shoulder piece E, serving to join
internally the external supporters..
The nut being larger than the box at the part where the supporter is set,
prevents it from sliding towards the exterior. The box is fixed to the nave of
the wheel in the usual manner.
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 13th December 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER
ARMAND le Comte DE FONTAINE MOREAU, of 4, South Street, Finsbury,
London, and 39, Rue de l'Echiquier, Paris, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of June, in the year of our Lord
One thousand eight hundred and fifty-four, in the eighteenth 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, adminis-
trators, and assigns, or such others as I, the said Peter Arniand 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 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 of "IMPROVEMENTS IN
THE CONSTRUCTION OF AXLE BOXES," communicated to me by 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

page_text: 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 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 ascertained in and
by the following statement thereof, reference being had to the Figure of the
Drawing hereto annexed, and to the letters marked thereon, that is to say:-
The Invention communicated to me consists in an improved mode of con-
structing the oil chambers of the axle boxes of wheel carriages, to improve the
lubricating of the axles.
The accompanying Drawing is a plan of the new incchanical arrangements;
in which, A represents the journal; B, oil chamber; C, C, supports; D, nut;
E, shouldering; F, cap; G, orifice for the introduction of the oil; H, cap;
I and K, leather washers; J, caoutchouc washer. The oil chamber B is, as
in the ordinary construction of axle boxes, enclosed in the nave of the wheel;
it is of a trun-conical form, its greatest width being on the inner side next the
vehicle. The chamber B is provided internally and near each of its two
extremities with bearings or circular supports C, C, upon which the journals
of the axletree bear, without touching any other part of the oil chamber B;
between these supports is a space for containing oil. The oil chamber is closed
on the outer side by a cap F and nut D. To close the chamber B on the
inner side, I place behind the inner support C, C, two vulcanised india-rubber
and leather washers I and J, superposed, and behind them a leather washer
K, which are all adjusted inside the chamber B by a cast-iron cap H and
screw.
The leather washer superposed ou the india-rubber washer forms a perfect
junction with the support .C, C, and the other part of the packing entirely
surrounds the axle. To cause the packing to adhere to the support C, C, I
tighten the cap H means of its screw, which forces the washer I against
the support C, C, and to adhere to the axle; the bands thus form an elastic
ring round the journal, and prevent the escape of the oil which constantly
lubricates the supports and journal. The oil chamber B being set in the space
between the supports C, C, the oil is introduced through the orifice G, which
is closed after its introduction.
The journal is furnished with a shoulder piece, so placed that it joins
internally the external supports of the oil chamber; this shoulder piece serves
to keep the chamber in its position, and maintains the journal in its proper
position. The nut D being larger than the chamber at the part where the
outer support C, C, is set, prevents it from sliding towards the exterior.

page_text: The journal A is introduced into the chambers B at the inner side, where
the chamber is the widest. The packing is bevelled off so as to enter the cap
H, where it is fixed permanently, and prevented from being drawn along by
the action of the journal when it enters the chamber.
And having now described the nature of the Invention communicated to
me, and the manner of carrying the same into effect, I wish it to be under-
stood that I do not confine myself to the precise details of construction herein
laid down; but what I claim as new, and intended to be protected by the said
in part recited Letters Patent, is,-
The new mode of constructing the oil chambers of axle boxes for improving
the lubricating of the axles of wheel carriages, as herein-before described, and
referred to in the accompanying Drawing.
In witness whereof, I, the said Peter Armand le Comte de Fontaine
Moreau, have hereunto set my hand and seal, this Twelfth day of
December, in the year of our Lord One thousand eight hundred and
fifty-four.
L' DE FONTAINE MOREAU. (L.S.)
