PROVISIONAL SPECIFICATION left by the said Jules de la Coux des
Roseaux at the Office of the Commissioners of Patents, with his Petition,
on the 6th April 1867.
1, JULES DE LA COUX DES ROSEAUX, of No. 60, Boulevart de Strasbourg,
Paris, in the Empire of France, Merchant, do hereby declare the nature of
the said Invention for "AN IMPROVED LUBRICATOR FOR OILING AXLES AND OTHER
MOVING PIECES OF MACHINERIES," to be as follows:-
This improved lubricator is on the same principle as the one already
Patented by me on the 6th April 1864, under the No. 855, the lubricating
liquid being introduced in a glass or other rather small vessel tightly stopped;
a thin metallic tube entirely open at one end, and closed at the other by a
little cap perforated at its centre by a very small hole, is introduced through
the stopper, the open end being turned upward; the oiling vessel being then
overturned, the open end of the tube is introduced through the cap of any
axle bearing or other moving piece of machinery which the tube must not
touch; the oil or other lubricating liquid according to physical law cannot run
out, but the motion of the axle or other moving piece will carry away a small

page_text: drop of the liquid which causes a partial vacuum in the vessel, then the
pressure of the atmosphere will force in the vessel a small air bubble to supply
the escaped liquid, which in the same time runs through a small side perforation
of the tube and supplies the drop carried away; the same effect takes place as
long as there is lubricating liquid in the vessel.
The principal improvement in this lubricator consists in the small thinly
perforated cap for stopping the upper part of the tube, permitting this latter
to be cleaned out when clogged by coagulated oil.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jules de la Coux des Roseaux in the Great Seal Patent
Office on the 5th October 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JULES DE
LA COUX DES ROSEAUX, of No. 60, Boulevart de Strasbourg, Paris, in the Empire
of France, Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of April, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Jules de la Coux des Roseaux, Her special licence that I, the
said Jules de la Coux des Roseaux, my executors, administrators, and assigns,
or such others as I, the said Jules de la Coux des Roseaux, 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 "AN IMPROVED LUBRICATOR FOR OILING AXLES
AND OTHER MOVING PIECES OF MACHINERIES," upon the condition (amongst
others) that I, the said Jules de la Coux des Roseaux, 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 Jules de la Coux des Roseaux, do
hereby declare the nature of my said Invention, and in what manner the

page_text: same is to be performed, to be particularly described and ascertained in and
by the following statement :-
This little apparatus of very easy application and essentially practical, is
intended to lubricate in a self-acting and regular and continuous manner all
the rubbing parts of machines or mechanical apparatuses. It is composed of a
very thick glass réservoir of a suitable shape having a somewhat narrow orifice,
in which if desired a screw thread may be formed to receive a copper ferrule
or collar, this latter, which may be fitted and cemented outside, is itself tapped
exteriorly at the part which comes outside the reservoir to receive a cover or
lid which hermetically closes the reservoir by means of a leather or india-rubber
washer. The lid receives in its centre a small tube made adherent by solder
or otherwise, the upper part of which plunges in the reservoir, and is closed by
a small cap entering exactly, in order to intercept the passage of the lubricating
fluid which cannot issue from the reservoir but by a small hole of the diameter
of a rather fine needle pierced in the tube a little above the joint of the lid.
The reservoir being filled with oil its lid is screwed on the ferrule or collar.
The small tube forming neck, and which is open at its upper part, is then turned
over and is placed in the central lubricating hole of the cap, and of the upper
bearing, where turns the shaft or axle as may be seen on the Sheet of Drawing
hereunto annexed, care being had that the end of the tube comes very near the
axle but without touching it.
This lubricator is shewn full size on the accompanying Sheet of Drawing
forming part of this my Specification; Figs. 1 and 2 are separate views of the
pieces which compose it represented in section; and Fig. 3 represents the
lubricator in position on a revolving shaft pedestal.
The oil or other Inbricating liquid cannot issue from the reservoir A to
which air has no access, but the little rounded drop which slightly projects at
the orifice of the tube D is drawn and carried away by the movement of the
shaft B on which it comes in contact, this carrying away of liquid molecules
naturally creates a vacuum in a corresponding space of the reservoir into
which the outer air penetrates in small air bubbles which pass by the small
hole a pierced in the centre of the stopper or cap 6, and this air in penetrating
into the reservoir expels the same quantity of oil which passes by the small
hole c of the tube D and descends in its turn until in contact with the shaft B.
To fill the reservoir A with oil it is only necessary on reversing this reservoir to
unscrew the lid C, and to pour in the oil by the aid of an oil can, then to
rescrew the lid on the ferrule or collar F, and to place the tube D in the hole
of the cap E; if this hole is too small it is bored, if on the contrary it is too
large the tube D is surrounded with tow to form a tight packing, if this tube

page_text: is thick enough it may even be tapped to be screwed in the bearing, but it
must never touch the shaft, therefore if this tube D were too long it would
be requisite to cut it, but it must always enter very exactly into the lubricating
hole in order to intercept all passage of air. The little cap a enters with
friction into the tube D of which it stops the upper part in order that it may
be lifted out if necessary to clean this latter. When it is desired to place
this lubricator on a pedestal, the bearings must first be carefully cleaned
in order that there may not be left a trace of coom or gome; the oil drawn
away by the rotary motion of the shaft issues drop by drop, this oil is replaced
by as many air bubbles; it ceases to flow only with the cessation of the motion,
and only recommences with the first evolutions of the shaft, and always in
proportion to the speed until there is no more oil in the reservoir, which is
easily perceived because the reservoir is transparent.
In conclusion, I claim as my exclusive property the particular arrangement
of the self-acting lubricator above described, based solely on a physical law
which renders its action regular and certain.
In witness whereof, I, the said Jules de la Coux des Roseaux, have
hereunto set my hand and seal, this First day of October, in
the year of our Lord One thousand eight hundred and sixty-
seven.
