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."
Sealed the 6th April 1863, and dated the 15th October 1862.
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 15th October 1862.
J, JEAN BAPTISTE GABRIEL MARIE FRÉDÉRIC 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 oil box for lubricating all kinds of
axles and bearings, and especially carriage axles; it consists, 1st, in obtaining
a continual rise and spread of the oil from a lower reservoir over the surface
of the axle. 2nd, by a partition placed at the lower part of the axle box,
which prevents any escape of oil at the back of the reservoir caused by the
motion of the vehicle. 3rdly, of an improved coupling fixed behind the
journal, which prevents all lateral spread of the oil from the box along
the axle. 4thly, in. the application of a guard plate for preventing the intro-
duction of any foreign matter into the oil-box.
In the annexed Drawing is represented one arrangement of this improved

page_text: oil box, Fig. 1 of which shows a central vertical section of the box on line
1, 2, Fig. 3; Fig. 2 shows a central vertical section of the same on line 3, 4,
Fig. 1; while Fig. 3 shows a plan of the oil box. The same letters of reference
indicate the same parts in the three Figures seen in different positions.
d
a, upper part of the box, having a reservoir b, into which the liquid is
distributed when raised; c, lining on the under part of a; d, lower part of the
oil box; e, diaphragm cast on part d, of curved form, forming with part
a box from which the oil cannot escape; f, emptying plug of box d; g, ring
furnished with curved projections so arranged as to work in both directions,
and turning freely between surface h in front of box a, d, and surface i of
cover of said box. The ring rotates on the end of the journal, being fixed
thereto by a small key k. It will be readily understood that by the rotation
of ring g the curved projections of the latter will raise the oil from lower
part d, and deliver it into upper part 6 over the journal of the axle; j, cover
enclosing ring g, which turns in an inner circular rim ; this cover is fixed to
the two parts a, d, of the oil box, and has at the upper part a small opening m
for the introduction of the oil; n, disc, furnished with a rim o cast on the
parts a, d, of the oil box; the object of this arrangement is to prevent dust
and foreign matters penetrating into the oil box; p, ring fixed on the axle,
for preventing the oil from escaping from the oil box.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jean Baptisto Gabriel Marie Frédéric Piret in the Great
Seal Patent Office on the 13th April 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
BAPTISTE GABRIEL MARIE FRÉDÉRIC PIRET, of 29, Boulevart St. Martin,
Paris, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letter's
Patent, bearing date the Fifteenth day of October, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Jean Baptiste Gabriel Marie Frédéric Piret, Her special licence,
that I, the said Jean Baptiste Gabriel Marie Frédéric Piret, my executors,
administrators, and assigns, or such others as, the said Jean Baptiste
Gabriel Marie Frédéric Piret, my executors, administrators, and assigns,
should at any time agree with, and no others,, from time to time and at all

page_text: 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 Frédéric Piret, 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 per-
formed, 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 Jean Baptiste Gabriel Marie Frédéric
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.an improved oil box, or that of any other liquid or
lubricating apparatus. for. lubricating all kinds of axles, and especially railway
carriage axles, the characteristics of which are, 1st, a continual rise and spread
of the liquid obtained from a lower reservoir over the surface of the axle.
2ndly, a partition placed at the lower part of the axle box, which prevents any
escape of the liquid at back of the reservoir caused by the motion of the
vehicle. 3rdly, an improved coupling or stuffing box fixed behind the journal,
which prevents all lateral spread of the liquid from the box along the axle.
4thly, the application of a guard plate for preventing the introduction of any
foreign matter into the box.
.
In the annexed Drawing is represented one arrangement of this improved
lubricating apparatus, Fig. 1 of which represents a central vertical section of
the box; Fig. 2, a transverse section of the circular chamber; Fig. 3, plan;
Fig. 4, detail of the liquid-raising apparatus acting in either direction; Fig. 5,
detail of another arrangement of the helical wheel of modified form; and
Fig. 6, detail of packing with inner stuffing box. The same letters of reference
indicate like parts in all the Figures seen in different positions.
A, upper part of the box on which the carriage spring rests; B, reservoir
for receiving the liquid when raised; C, brass lining for receiving the whole
friction of the journal; _D, lower-part-of the box containing the reservoir for
oil or any other liquid, and having at the front on the exterior an opening E,

page_text: closed hermetically, by which the liquid is introduced from time to time, as it is
used; a partition F is placed in the interior, inclining forwards to prevent too
great agitation of the oil by the motion of the carriage; G, ear piece cast on
part D, carrying the screw of the axle packing ring; the two parts A; D,
forming the axle box are connected together by two strong bolts, which serve
at same time for securing the box to the points of suspension from the
carriage; H, screw plug, by which access is had for cleaning and emptying
the box; I, helical wheel with curved projections or cups for raising the
liquid; this wheel turns in a circular recess contrived in front of the two
parts of A, D, and solidly secured on the end of the journal by means of two
rivets J with dovetail beads received in a groove of similar form made longi-
tudinally in the end of the journal. The helical wheel I may be modified in
the form of its inclined planes, as seen in Figs. 4 and 5, in order that the
liquid shall be always raised, whatever may be the distance between it and.
the vertical plate in from of which it turns.
In the arrangement seen at Fig. 4 the helical wheel is intended to turn in
contact with the vertical plate, and in Fig. 5 it turns about half an inch from
it, in order to prevent friction. L, M, stuffing box formed of two parts fitting
one in the other, and receiving the packing in the interior; this stuffing box.
is placed on the exterior of the box, and bears on a leather collar between it.
and the rear face of the axle box A, D; this said stuffing box is held rigidly
in position and pressed by the conical frame N, which is slid vertically between
clamps O by means of bolt P, Q.
Fig. 6 represents another arrangement of packing formed of two parts
enclosed one within the other, and fitted in a groove cast on the rear end
of the journal box A, D. R, leather collar for preventing the admission of
dust.
Having described the nature of my Invention, and the manner of per-
forming 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, the application of a wheel or disc with projecting cup arms for con-
tinuously raising the liquid from the lower to the upper part of the box, and
distributing it over the surface of the journal, as described and represented in
the Drawing.
Secondly, I claim the application of a partition for preventing the escape of
the liquid, in the manner described.
Thirdly, I claim the application of a coupling or stuffing box in combi-
nation with the axle to prevent the liquid escaping along its surface.

page_text: Fourthly, I claim the application of the mode of fixing the helical wheel
to the end of the journal, as it is described above and represented in the
Drawing.
Fifthly, I claim the application of a guard plate for preventing the intro-
duction of any extraneous matters, all as described and represented in the
Drawing annexed.
In witness whereof, I, the said Jean Baptiste Gabriel Marie Frédéric
Piret, have hereunto set my hand and seal, this Eighth day of April,
in the year of our Lord One thousand eight hundred and sixty-three.
