AN IMPROVED APPARATUS FOR THE LUBRICATION OF BEARINGS SHARTS OR OTHER PARTS OR MACHINERY SUBIECT TO FRICTION."
Year: 1863

page_text: LETTERS PATENT to Pierre Augustin Sautreuil, of Fécamp, France,
for the Invention of "AN IMPROVED APPARATUS FOR THE LUBRICATION OF
BEARINGS SHARTS OR OTHER PARTS OR MACHINERY SUBIECT TO FRICTION."
PROVISIONAL SPECIFICATION left by the said Pierre Augustin Sautreuil
at the Office of the Commissioners of Patents, with his Petition, on the
4th November 1863.
I, PIERRE AUGUSTIN SAUTREUIL, of Fécamp, France, do hereby declare
the nature of the said Invention for "AN IMPROVED APPARATUS FOR THE
LUBRICATION OF BEARINGS, SHAFTS, OR OTHER PARTS OF MACHINERY SUBJECT TO
FRICTION," to be as follows:-
The physical principle of acting of this improved lubricator is based on the
resistance offered by the atmospheric air against the exit of a lubricating
liquid contained in a vessel with narrow neck turned upside down, with the
exit opening situated in close contact with the moving part to be lubricated
so as to cause the liquid to be drawn off from the vessel by the effect of the
frictional motion of the moving parts.
My improved lubricator is intended for the lubrication of bearings, journals,
steps, shafts, axles, spindles, or other parts of machinery subject to friction
arising either from rotary or reciprocating motion, the same consists of a
suitable vessel or phial of glass, metal, or other suitable material, in the neck
of which is cemented or otherwise air-tight fixed a metal tube, in the free end

page_text: of which fits a stopper pierced in the direction of its axis with a narrow hole
for the exit of the oil or other suitable lubricating liquid from the vessel
when this latter after having been filled with this liquid is inserted upside
down in a corresponding perforation provided in the cap or upper part of the
bearing in such manner that the opening of the stopper hole be in close
contact with the shaft axle or other moving part to be lubricated, the mole-
cular or capillary attraction resulting from the frictional motion, causing the
liquid to be drawn off by little and little from the interior of the vessel,
whereas the vacuum which forms in this latter above the lubricating liquid
will prevent the exit of this latter when the motion of the shaft or other
moving part is interrupted.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Pierre Augustin Sautreuil in the Great Seal Patent Office
on the 4th May 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PIERRE
AUGUSTIN SAUTREUIL, of Fécamp, France, 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 sixty-three, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Pierre Augustin Sautreuil, Her special licence that I, the said
Pierre Augustin Sautreuil, my executors, administrators, and assigns, or such
others as I, the said Pierre Augustin Sautreuil, my executors, adminis-
trators, 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 APPARATUS FOR THE LUBRICATION OF
BEARINGS, SHAFTS, OR OTHER PARTS OF MACHINERY SUBJECT TO FRICTION," upon the
condition (amongst others) that I, the said Pierre Augustin Sautreuil, 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.

page_text: NOW KNOW YE, that I, the said Pierre Augustin Sautreuil, 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:-
The Invention consists in a lubricating apparatus to be applied to the
frictional parts of machinery to be lubricated; the physical principle of acting
on which the arrangement of the apparatus is based is the resistance exerted
by the air against the exit of any suitable lubricating liquid, such for instance
as oil or others, from an inverted vessel with narrow outlet opening in which
the said oil or other lubricating liquid is contained, and which is prevented
from flowing out of the vessel unless solicited by the motion and the friction
of the moving parts to which the apparatus is applied, in such manner that
the quantity of lubricating liquid which leaves the vessel is in direct ratio
with the speed of the motion imparted to the frictional parts, the flow of the
lubricating liquid consequently ceasing entirely during the time the moving
parts are at rest.
In the annexed Drawings the apparatus is represented in Fig. 1 in outside
elevation, and in Fig. 2 in sectional view over the line x, y, of the plan view
Fig. 3; in these three Figures the same letters of reference indicate corre-
sponding parts.
a is the vessel for containing the oil or other suitable lubricating liquid,
the said vessel is made of glass, metal, or other suitable resisting material,.
and in the neck thereof is cemented or otherwise hermetically sealed a tube 6
of brass or other suitable metal or material, in the free end of which tube fits
a plug c of metal, wood, or other suitable resisting material provided in the
direction of its axis with a perforation or hole d forming the exit opening for
the lubricating liquid, the diameter of which hole or perforation depends on
the average speed and the amount of frictional surface to be lubricated by the
apparatus, consequently spare plugs with holes of various diameters must be
provided. In Fig. 2 the apparatus is represented ready for working, the
exit opening of the plug c resting on the trunnion or revolving arbor G,
the tube b being inserted freely in a corresponding hole perforated in the cap
F and upper brass H of the bearing H'.
The mode of applying the apparatus to frictional parts of machinery, and
the mode of acting of the same is as follows:-The plug c having been
removed from the tube b the vessel a and the tube bare filled with oil or
other suitable lubricating liquid to be made use of, after which the plug c is
replaced in the tube b; the vessel is now turned upside down and in this
position inserted in the manner as represented in Fig. 2, in the perforation

page_text: provided in the cap F and upper brass H when by its own weight the free
end of the plug c will bear against the revolving shaft or trunnion G to be
lubricated, for which purpose the diameter of the said perforation although
corresponding nearly with that of the tube 6 and plug c, must allow these
latter to descend freely by their own weight till the plug comes in contact
with the shaft or trunnion G, which latter by being in contact with the end
of the exit opening d and by the effect of the revolving motion will constantly
draw off a small portion of the lubricating liquid contained in the vessel a,
whilst the vacuum thereby formed in the top of this latter will effectually
prevent the liquid from leaving the vessel unless solicited by the motion of
the frictional parts, whilst as soon as this motion ceases any further escape
of the lubricating liquid from the vessel a is at once prevented.
Having thus described and particularly ascertained the nature of my
Invention, the manner of applying the same to parts of machinery submitted
to friction, and the mode of working the apparatus, I wish it to be understood
that I do not intend to restrict or restrain myself to any special shape or size
of the apparatus described, but what I consider to be novel and original and
therefore claim as the Invention secured to me by the herein-before in part
recited Letters Patent, is, the general arrangement of the apparatus and
its mode of acting when applied in the manner described to moving parts of
machinery subject to friction.
In witness whereof, I, the said Pierre Augustin Sautreuil, have here-
unto set my hand and seal, this Sixteenth day of April in the year
of our Lord One thousand eight hundred and sixty-four.
Witness,
A. POTEL.
