page_text: LETTERS PATENT to Jean Baptiste Gabriel Marie Frédéric Piret, of
29; Boulevart St. Martin, Paris, Civil Engineer, for the Invention of
"IMPROVEMENTS IN LUBRICATING APPARATUS.'
PROVISIONAL SPECIFICATION left by, the said Jean Baptiste Gabriel
Marie Frédéric Piret at the Office of the Commissioners of Patents,
with his Petition on the 10th March 1862..
I, JEAN BAPTISTE: GABRIEL MARIE: FREDERIC PIRET, of 29, Boulevart
St. Martin, Paris, Civil Engineer, do hereby. declare the nature of the said:
Invention for IMPROVEMENTS IN LUBRICATING APPARATUS;" to be as follows:-
My Invention relates to an improved apparatus, which I term a helico--
winged crown, represented in the: Drawings annexed;, showing the journal.
of a railway carriage axle with my improved apparatus applied thereto..
Fig. 1 is a longitudinal vertical section of the apparatus; Fig. 2 a transverse
vertical section of the same; Fig. 3 a plan; while Fig. 4: represents details..
On examining these Figures the arrangement and working of the apparatus
will be readily understood. a, b, c, cast-iron axle box formed of three parts.
solidly connected together; the part a receives the brass lining d, upon which:
is exerted the friction of the axle, the second b-serves to enclose the axle ; and
the third c forms the fore part, and contains the helico-winged crown e, which.

page_text: the
forms the main feature of my Invention; it is composed of a ring f, set and
held on the end of the axle by a key, on the periphery of this ring fare placed
the pallets or wings in a curved or oblique direction to the axle, joined together
two and two and in contrary directions, so as produce the lifting of the lubri-
cating liquid in both directions; it must be understood that the number of
wings or pallets, and their curve and inclination, may be varied without in any
way changing my principle as above described. h is a flat part forming a
partition between the two parts of the oil box a, b, against. which part turns
the ring f, on which ring are fixed the curved wings or pallets; this straight
part has an opening in the top communicating with the chamber j, cast with
upper part of the box a, and it is into said chamber that the liquid or oil
is discharged on being raised by the helico-winged crown e; c is a cover already
mentioned, which is placed in front of the two parts a and b; this cover has a
concentric crown i fitting on the part of the box a, b, and covering the
helico-winged crown so as to prevent any projection of the liquid; k is a lid-
closing a rectangular opening in the box c, through which opening, the liquid
I is introduced; m is a coupling box, with circular grooves, working into similar
grooves cast in the lower part of box b, for the purpose of preventing friction
and also all loss of liquid contained in the interior of the box b. Besides
said arrangement a small channel may be added, uniting the bottom of the
grooves in the interior of the box 6 to permit the flow of the liquid contained
in the empty spaces of the circular grooves.
From the description I have given above, it is easy to understand that the
axle in its rotary motion carries with it the crown, the helical wings of
which, from their form and inclination, and also the flat part against which
they turn carry a quantity of liquid; which is projected into the opening in the
part h, thence said liquid drops into the chamber j, from whence it disperses
itself into the interior of the lining d. It must be understood that.this helico-
winged crown is applicable to all kinds of journals, whatever be their form
or arrangement or the nature of the lubricating liquid: to be raised.n
The principal feature of my Invention' is the application of. the helico
winged crown, as above described,, turning against a flat surface soi as
to raise the lubricating liquid; for the purpose and in the manner above
specified..

by the said Jean Baptiste Gabriel Marie Frédéric Piret in the Great
Seal Patent Office on the 8th September 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I JEAN BAP-
TISTE GABRIEL MARIE FRÉDÉRIC PIRET, of 29, Boulevart St. Martin, Paris,
Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of March, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Jean Baptiste Gabriel Marie Frederic Piret, Her special licence that I, the
said Jean Baptiste Gabriel Marie Frederic Piret, my executors, administrators,
and assigns, or such others as I, the said Jean Baptiste Gabriel Marie Frederic
Piret, 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 LUBRICATING
APPARATUS," upon the condition (amongst others) that I, the said Jean Baptiste
Gabriel Marie Frederic Piret, 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 Jean Baptiste Gabriel Marie Frederic
Piret, 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 Sheet of Drawings
hereunto. annexed, and to the letters and figures marked thereon (that is
to say:
My Invention relates to improved apparatus for lubricating railway carriage
axles, and shafts of machinery in general. In the annexed Drawing I have
represented a railway carriage axle fitted with the improved lubricating
apparatus of my Invention.
Fig. 1 shows a longitudinal vertical elevation; Fig. 2, a transverse vertical
section; and Fig. 3, a plan of this improved lubricator; while Figs. 4 and 5
show details of the same.

page_text: On examining these Figures, the method of operation and the arrangement
of the apparatus will be readily understood. a, b, c, is a cast-iron axle box
formed of three parts united together; the part a is furnished with a brass
lining d, for receiving the friction of the journal; the part 'b encloses the
under part of the same; while part c forms the front plate enclosing the
lubricator e of my Invention. This lubricator is formed of a ring:f fixed on the
end of the journal; on the periphery of this ring are formed two projections. e
each of an extent equal to about one-fourth of its circumference, and at opposite
diameters thereof, the ends of these projections are cupped or curved obliquely
to the axis in contrary directions in order to raise the lubricating liquid during
the rotation of the journal in either direction. The number of these cupped
projections may be varied, as also, their form and inclination, without departing
from the principle of my Invention. h, fixed disc, on which the ring f carrying
the cup projections bears in its rotation; this disc has an opening at the upper
part communicating with a chamber at the upper part of the axle box a,
into which the liquid raised by the cups e passes; c,.front plate before mentioned,
having a cap i adjusted to disc h, and surrounding the cupped projections so
as to prevent the liquid from splashing; k, lid closing a rectangular opening
in box c for the introduction of the liquid ; m, coupling, furnished with
circular grooves, made in the bottom plate 6 of the axle box, to prevent friction
and waste of liquid contained therein. I may also make a small channel
connecting the bottom of the grooves with the interior of b, to allow of an
escape for any liquid, that may be in the spaces of the circular grooves ;. n
covering disc, represented in longitudinal section at Fig. 1, and in detail,
Fig. 5. This disc is formed of two parts, and embraces a circular flange o on
the axle box, which enables it to be easily mounted and dismounted when
required.
From the foregoing description it will be readily understood that the journal
being in motion carries with it the cupped projections carried by the ring
keyed on its end, which from their form and inclination, as also by reason of
their contact with disc h, carry with them a quantity of liquid, which will be
projected through the opening in disc h, and thence fall into chamber j, where
it distributes itself within the lining d of the journal. It will be understood
that this improved lubricator may be applied to all kinds of bearings, what-
ever may be their form and arrangement or the nature of the liquid to be
raised.
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,-

page_text: First, the application of a ring furnished with cupped projections turning in
contact with a fixed disc for the purpose of raising any liquid suitable for lubri-
cating the frictional surfaces of bearings in general, as herein described and
represented in the Drawings annexed.
Secondly, I claim the improved coupling or junction piece m, with circular
grooves, whereby to prevent all friction and loss of liquid contained in the axle
boxes, which couplings are applicable to railway carriages or for machinery in
general as described.
Thirdly, I claim the use and application of a covering disc, or annular plate
n, adjusted on a circular flange at the back part of the axle box, as before
described.
And, lastly, I claim the arrangement and combination of parts con-
stituting a lubricating apparatus, as and for the purposes herein-before
described.
In witness whereof, I, the said Jean Baptiste Gabriel Marie Frédéric
Piret, have hereunto set my hand and seal, this Fifth day of
September, in the year of our Lord One thousand eight hundred and
sixty-two.
