Year: 1859

page_text: LETTERS PATENT to Etienne Juzet, of 29, Boulevart St. Martin, Paris,
in the Empire of France, Mechanician, for the Invention of "IMPROVE-
MONTO IN LUDI A
PROVISIONAL SPECIFICATION left by the said Etienne Juzet at
the Office of the Commissioners of Patents, with his Petition, on the
4th November 1859.
I, ETIENNE JUZET, of 29, Boulevart St. Martin, Paris, in the Empire of
France, Mechanician, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN. LUBRICATING APPARATUS," to be as follows:-
My Invention relates to an oil box or lubricator for lubricating the axles of
railway and other carriages. In this box the journal or bearing of the axle
is completely enclosed so that no dust or foreign matters can, enter; one-half
of the surface of the axle is continually in the oil.
I have represented in the annexed Drawing a central vertical section of the
box according to my Invention. a, journal of the axle; b, oil receptacle
under part of the box forming the outside; c, upper part of the box; d, bearing;
e, elastic ring or washer (of leather, india-rubber, gutta percha), which
prevents the oil escaping at that part; f, channel for the introduction of the
oil; g, cover closing hermetically the channel f; for this purpose it is faced
with leather, so that when shut the air enclosed in the box maintains the level
of the oil at the height of the centre of the journal; h, spring which acts on the
cover g to close it; i, plates of the springs supporting the carriage; j, cover,
k, bolts holding these, parts together.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ETIENNE
JUZET, of 29, Boulevart St. Martin, Paris, in the Empire of France,
Mechanician, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of November, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Etienne Juzet, Her special licence that I, the said Etienne
Juzet, my executors, administrators, and assigns, or such others as I,
the said Etienne Juzet, 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 "IMPROVE-
MENTS IN LUBRICATING APPARATUS," upon the condition (amongst others).
that I, the said Etienne Juzét, my executors or administrators, by an instru-
ment 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Etienne Juzet, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the Sheet of Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say):-
My Invention relates to an oil box or lubricator for lubricating the axles of
railway and other carriages. In this axle box the journal or bearing of the
axle is completely enclosed so that no dust or foreign matters can enter; one-
half of the surface of the axle is continually in the oil.
I have represented in the annexed Drawing at Fig. 1 a side view, Fig. 2
a plan, & at Fig. 3 a central vertical section of the axle box according to
my Invention.
a, journal of the axle; b, oil receptacle, lower part of the box
forming the front; c, upper part of the box; d, bearing; e, elastic bearing or
ring resting in a groove e', made in the axle. This ring can be made of india-

page_text: rubber or gutta percha. In that case I cover the part in contact with the
axle with a thin sheet of copper to prevent the dilatation produced by the
friction on the india-rubber or gutta percha. If this ring is of common leather
I surround its exterior part with a sheet of india-rubber to afford the necessary
elasticity. This annular piece can also be made of wood or it may be of
metal in pieces forced up by elastic packing, & of any suitable form other
than as described.
Instead of the ordinary arrangement I can dispense with the groove e¹,
and place the ring on the circumference of the axle; f, channel for the
introduction of oil. Between the channel and the reservoir is a space
enclosing air, which by its pressure forces the oil to remain at the same
elevation, that is to say, half covering the journal; g, cover closing hermetically
the channel f; for this purpose it is faced with leather, so that when shut the
air enclosed in the box maintains the level of the oil at the height of the
centre of the journal; h, spring which acts on the cover g to close it; i, plates
of the springs of the carriage. In this box the suspension springs of the
vehicle are fitted into instead of being held by a strap to the upper part of
the box; j, cover; k, bolts holding the parts together.
The advantages resulting from this new lubricator are,-
1st. To prevent the deviation of the blades of the springs after being in use
a length of time, which is the case in other lubricating axle boxes.
2ndly. In the application of a pressure of air which causes the oil to remain
at a uniform level.
3rdly. Preventing dust or foreign matters entering the box, and in the
same way preventing the escape of oil by the rotation of the axle.
Having described the nature of my Invention, and the manner of performing
the same, I declare that what I claim as my Invention, to be protected by the
herein-before in part recited Letters Patent, is,-
First, fitting the lubricating box to the springs i as described.
Secondly, the application of an elastic ring or bearing surface e hermetically
closing the box towards the journal.
In witness whereof, I, the said Etienne Juzet, have hereunto set
my hand and seal, this Twentieth day of April, in the year of our
Lord One thousand eight hundred and sixty.
ETIENNE JUZET. (L.S.)
