Year: 1875

page_text: LETTERS PATENT to Marie Antoine Jules de la Coux des Roseaux,
of Asnières, near Paris, France, for the Invention of "IMPROVEMENTS
IN LUBRICATORS AND OIL FEEDERS."
i
Sealed the 4th January 1876, and dated the 13th September 1875.
PROVISIONAL SPECIFICATION left by the said Marie Antoine, Jules,
de la Coux des Roseaux at the Office of the Commissioners of,
Patents, with his Petition, on the 13th September 1875.
I, MARIE ANTOINE JULES DE LA COUX DES ROSEAUX, of Asnières,.
near Paris, France, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN LUBRICATORS AND OIL FEEDERS," to be as follows:-..
My Invention relates to improvements in lubricators and oil feeders
for machinery, and consists, first, in the application to lubricators+of
different kinds of a filter of wire cloth or perforated metal, by which any
foreign substances that may be contained in the oil are retained and
prevented from clogging the oil passage to the bearing or other part of
the machine to be lubricated. This filter is preferably in the form of a

page_text: cylinder closed at top, and fitting at bottom over the tube or other
outlet, so as to prevent any outflow of the oil except through the meshes
or perforations of the filter.
Another improvement consists in providing glass lubricators with two
openings, one at top and the other at bottom. The upper one is closed
by a plug or a screw cap, and it has for its object to enable the lubricator
to be refilled with oil when required without the inconvenience of having
to dismount the entire lubricator for the purpose, as is the case with
those lubricators which have but one aperture. The lower aperture is
closed by a plug or screw cap, to which is fitted the tube by which the
oil is conveyed where. required. This lower aperture admits of ready
access to the filter and oil passage to clean the same when necessary.
Another improvement in glass lubricators consists in the means of
making a joint at the lower aperture by the direct contact of the glass
mouth with the leather or other packing in the screw cap. Hitherto it
has been usual to cement upon the neck of the oil receptacle a metal
collar having an inwardly projecting flange covering the edge of the
glass, the flange forming the joint with the leather packing. By this
arrangement the oil comes in contact with and destroys the cement by
which the collar is fixed, and the collar is liable to become loose in
consequence; but by my improvement I prevent all contact of the oil
with the cement by prolonging the glass beyond the screw collar, so that
the glass will come in direct contact with the packing of the collar.
The collar is fixed by cement, and also by a liead or shoulder on the
glass, over which the metal is turned down, so as to firmly retain the
collar; or the collar may consist of an alloy of tin or other metal cast
directly upon the glass.

the oil in the reservoir may be seen. In lubricators this frame consists
of top and bottom sockets in which the glass is fixed with leather 3
packings, the sockets being connected either by pillars or by a cylindrical

through which the oil receptacle may be seen.
For oil feeders having a glass receptacle the protecting envelope
consists of a network of wire enclosing the receptacle at a sufficient
distance therefrom to prevent the glass being broken by a blow or
fall.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Maric Antoine Jules de la Coux des Roseaux in
the Great Seal Patent Office on the 8th March 1876.
TO ALL. TO WHOM THESE PRESENTS SHALL COME, I, MARIE
ANTOINE JULES DE LA COUX DES 'ROSEAUX, of Asnières, near Paris,
France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of September, in the
year of our Lord One thousand eight hundred and seventy-five, in
the thirty-ninth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Mario Antoine Jules de
la Coux des Roscaux,. Her special licence that I, the said Marie
Antoine Jules de la Coux des Roseaux, my executors, administrators,
and assigns, or such others as I, the said Maric Antoine 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 thercin 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 LUBRICATORS AND OIL FEEDERS,"
upon the condition (amongst others) that I, the said Marie Antoine
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 performed, 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 Marie Antoine Jules de la Coux
des Roseaux, 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 accompanying Sheet of Drawings, and to the letters
and figures marked thereon, that is to say :-
My Invention relates to improvements in lubricators and oil feeders
for machinery, and consists, first, in the application to lubricators of
different kinds of a filter of wire-cloth or perforated metal, by which any
foreign substances that may be contained in-the-oil-are-retained_and
prevented from clogging the oil passage to the bearing or other part of
the machine to be lubricated. This filter is preferably in the form of a
cylinder closed at top, and fitting at bottom over the tube or other
outlet; so as to prevent any outflow of the oil except through the meshes
or perforations of the filter.
•
Another improvement consists in providing glass lubricators with two
openings, one at top and the other at bottom. The upper one is closed
by a plug or a screw cap, and it has for its object to enable the lubricator
to be refilled with oil when required, without the inconvenience of having
to dismount the entire lubricator for the purpose, as is the case with
those lubricators which have but one aperture. The lower aperture is
closed by a plug or screw cap, to which is fitted the tube by which the
oil is conveyed where required. This lower aperture admits of ready
access to the filter and oil passage to clean the same when necessary.
"'
Another improvement in glass lubricators consists in the means of
making a joint at the lower aperture by the direct contact of the glass
mouth with the leather or other washer or packing in the screw cap.
Hitherto it has been usuäl to cement upon the-neck of the oil.receptacle
å metal collar having an inwardly projecting flange covering the edge
of the glass, the flange forming-the-joint. with the leather washer. By
this arrangement the oil comes in contact with and destroys the cement
by which the collar is fixed, and the collar is liable to become loose in
consequence-but-by-my-improvement. I prevent all-contact-of-the-oil-
with the cement by prolonging the glass beyond the screw collar, so that
the glass will come in direct contact with the washer in the cap. The
collar is fixed by cement, and also by a bead or shoulder on the glass,.
over which this metal is turned down, so as to firmly retain the collar;

page_text: or the collar may consist of an alloy of tin or other metal cast directly
upon the glass.
Another improvement consists in the application to lubricators of
metal, or of glass enclosed in a metal case, of a gauge tube of glass
placed outside the metal case, to indicate the level of the oil in the
lubricator.
Another improvement consists in enclosing the glass receptacle of
lubricators and oil feeders in a metal frame having openings, by which
the amount of oil in the reservoir may be seen. In lubricators this
frame consists of top and bottom sockets, in which the glass is fixed
with leather packings, the sockets being connected either by pillars or
by a cylindrical casing, out of which large pieces have been stamped to
form apertures through which the oil receptacle may be seen.
For oil feeders having a glass receptacle the protecting envelope
consists of a network of wire enclosing the receptacle at a sufficient
distance therefrom to prevent the glass being broken by a blow or
fall
Figures 1, 2, 3, 4, 5, 6, and 7 are central vertical sections of different
kinds of lubricators to be fixed on bearings and other parts of machinery,
the said lubricators being provided with the improvements of my
Invention.
The same letters of reference indicate similar parts in all the Figures
wherever they recur.
Figures 1, 2, 3, 4, show various kinds of lubricators of ordinary con-
struction, with the metallic filter of my Invention applied. a is the oil
receptacle, made of glass, its mouth closed by a metal cap b screwing on
to a metal collar of the ordinary kind fixed on the neck of the vessel a.
In Figure 4 an ordinary wood plug is substituted for the screw cap b.
The means by which the oil is conveyed from the reservoir to the
bearing or other part of the machine to which the lubricator is applied
are different in these four Figures, but being all well known and forming
no part of my Invention it is unnecessary to describe them; they are
merely shown to illustrate the facility with which the first improvement
of my Invention may be applied to different kinds of lubricators. This

fixed by cement to prevent it turning when screwing on the cap.
glass neck passes completely through and projects beyond the collar f,
so that the glass mouth (which is ground true to make a tight joint)
alone comes in contact with the leather or india-rubber washer / in the
cap.
Instead of using.cement the collar may be in some cases cast directly
on the glass neck provided with a bead or shoulder g as before.
Figure 7 illustrates another construction of lubricator, more par-
ticularly intended for locomotives; it is provided with a metallic filter,
as before described, and is constructed in the following manner :- -The
glass vessel a has cylindrical sides, and a central aperture in the bottom
for the passage of the oil tube and filter; it is closed at top by a metal
cap forming part of the casing by which it is enclosed. The glass vessel
is enlarged at i, i, to fit the casing, as shown, to keep the latter at a
proper distance from the sides of the vessel a. The casing is composed
of a metal cylinder k having openings (or it may be an open frame),
and top and bottom covers m, n, screwed to the ends of the cylindrical
part . o, o, are leather seatings, by which the glass is fitted tightly in
the oncis

the ordinary opening at bottom) closed by a screw cap or plug, as and
for the purpose specified.
3rd. The means herein described of fixing the screw collars and
making a tight joint by the direct contact of the washer in the screw cap
against the glass mouth, as and for the purpose specified.
4th. The application to glass lubricators and oil feeders of a protective
metal-casing or envelope-of-wirework, substantially-as-shown-and-
described in Figures 7-and 8.
. 5th. The application to lubricators of the kind shown in Figure 7,
enclosed in a solid metal casing, of a glass gauge tube, as and for the
purpose set forth.
In witness whereof, I, the said Marie Antoine Jules de la Coux des
Roseaux, have hereunto set my hand and seal, this Sixth day of
March, in the year of our Lord One thousand eight hundred and
seventy-six.
