Company, Patent Agents, of 5, Southampton Buildings, Holborn,
in the County of Middlesex, for the Invention of "AN IMPROVED
LUBRICATOR." -A communication from abroad by Isidore Dreyfus,

Scaled the 9th June 1874, and dated the 10th December 1878.
COMPLETE SPECIFICATION filed by the said Alexander Browno at tho
Office of the Commissioners of Patents, with his Petition and
Declaration, on the 10th December 1873, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
BROWNE, of the Firm of Browne and Company, Patent Agents, of 5,
Southampton Buildings, Holborn, in the County of Middlesex, send
greeting.
WHEREAS I am in possession of an Invention for "AN IMPROVED
LUBRICATOR," and have petitioned Her Majesty to grant unto me, my
executors, administrators, and assigns, Her Royal Letters Patent for

page_text: the same, and have made solemn Declaration that it has been com-
municated to me from abroad by Isidore Dreyfus, of New York, in the
United States of America.
NOW KNOW YE, that I, the said Alexander Browne, do hereby
declare that the following Complete Specification, under my hand and 5
seal, fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed, in and by the following
statement :-
This Invention consists in the novel construction of a cup or vessel
for bubricating steam chests or cylinders with oil, tallow, congealed 1
or solidified grease, and other lubricating material or compound
automatically by the action of steam as hereafter described.
In order to explain this Invention I will now proceed to describe its
construction and operation, reference being had to the illustrative Sheet
of Drawings accompanying these Presents.
Figure 1 represents an external view of the cup or vessel as it actually
appears; Figure 2, a sectional view showing its interior construction and
working; Figure 3, a plan view of the points of connection of the yoke
Hand with the stationary pins G and G', and the slotted recess
H", as hereafter explained; and Figure 4, a plan view of the top of the
cup A and the position of the stationary pins G, G'. Similar letters
of reference are used to denote corresponding parts.
A. is the body of the oil cup which may be mado of glass, porcelain,
metal, or other suitable substance, and of any convenient size or shape
to hold oil or other lubricating material; B is a hollow stem or con-
nection between the body of the cup A, and the steam chest or cylinder
into which it may be screwed in the ordinary way. This stem or
connection is provided with a valve or cock C by means of which
communication between the cup and the steam chest or cylinder is
opened and closed at pleasure. It is also provided with a waste or
blow-off cock D for draining the cup A of its contents at such times and
in such manner as hereafter set forth. Both of these valves or cocks
are provided with handles or cranks that act independently of each other
in opening and closing the same. From the upper portion of the
stem B, as may be seen in Figure 2, projecting upwards into the centre

page_text: of the cup A is a tube E with an opening Y at the top and a hole X on
the side near the top; this tube is capable of being raised or lowered in
the cup A by the set screw F, F, in the upper portion of the stem B or
other suitable means for the purposes which shall be explained hereafter
when describing the operation of the cup A, and the functions of tho
tube E in connection therewith. The two stationary pins G and G'
screwed firmly into flanged projections in the upper part of the cup A,
the moveable yoke H and H, and the screw stem and handle I, is a
device to cover and uncover at will by means of the loose disc or cap J,
an opening in the centre of the top or covering of the cup A, for the
purpose of supplying that vessel with lubricating material when
necessary without the possibility of such disc or cap getting lost or
mislaid by accident or neglect.
Having thus explained its construction I will now explain by what
means and in what manner the action of the steam on the lubricating
material in the cup or vessel A is made by its peculiar construction, as
heretoforo described, to perform the desired automatic lubrication.
The cup A being nearly filled with oil, tallow, or other lubricating
material and screwed in the steam chest or cylinder, and the valvo or
cock C opened the steam rushes up through the stem B, and the tube E
melting by its heat and vapour the lubricating material to a liquid state,
and striking the top of the cup inside condenses and falling down in
drops of water at intervals in the oil or other lubricant sinks through, it
being heavier, to the bottom of the cup, displacing by this action an
cqual quantity of the lubricating material, and causing it to rise in the
cup, as may be seen in Figure 2, and flow over into the tube E through
the hole X, and trickling down through the tube and stem into the
steam chest or cylinder, by its own gravity reaches the parts to bo
lubricated, and steadily and surely accomplishes its work. Besides the
perfect circulation obtained between the steam chest or cylinder, and the
cup in imparting the steam and receiving the oil in return, the oil,
tallow, or other lubricating substance is refined and purified from the
acids and impurities inherent to them in their natural state by this
process, and remaining in the bottom of the cup can be drawn off or
blown out through the waste cock D when desired.
of the cup A into the cylinder or steam chest, as before described, is
The flow of oil out
regulated in quantity by raising or lowering the tube E in the cup by

page_text: the set screw F, F, as before explained, the effect of which is to increase
or diminish the condensing space in the cup above the oil level, producing
more or less water, and displacing more or less lubricating material to
feed the steam chest or cylinder as previously explained.
The method of filling the cup with the lubricant and the manner of
opening and closing the aperture in the cover of the cup for that
purpose by the mechanism before described is as follows:-The screw
stem I being relaxed the right arm of the moveable yoke H' slides out
from under the shoulder of the check pin G', where it has been held in
position by a slotted recess cut in its base at H" into which the stationary
pin G enters and holds fast when closed by the pressure of the screw
stem I, and the yoke thus loosened at this point swings round on the
other stationary pin G, which acts as a pivot, carrying with it the disc or
cap J and uncovering the aperture before-mentioned. The lubricant
being then placed in the cup the moveable yoke is turned round back
again to its usual position, and closing on the check pin G' by the
slotted recess in the base of the right arm of the moveablo yoko at H",
as shown in Figure 3, and the screw stem I being tightened up the
aperture is closed up steam and air-tight by the disc or cap J, the yoke
is held firmly in position and the operation is complete. I do not limit
myself however to this way of closing or covering the cup A or rather
the opening in the top of the same, as may be seen in sectional Drawing,
Figure 2, where the cap or cover is screwed on in the ordinary way.
When the supply of oil or other lubricating material is exhausted and
the cup becomes full of water (condensed steam), the connecting valve
or cock C should be closed and the waste cock D opened to allow the
water and impurities remaining in the cup to be drawn off; these may
be also blow out if necessary by opening the connecting valve O and
letting steam into the cup, sufficient for that purpose; the cup can then
be refilled as before described.
Having now described the nature and object of this Invention for
"An Improved Lubricator," and in what manner the same may be
carried into practical effect, I would remark in conclusion that what I
claim as new and desire to secure by Letters Patent is, constructing a
cup or vessel for lubricating steam chest or cylinders with oil, tallow,
congealed or solidified grease, and other lubricating material or compound

page_text: automatically by the action of steam, substantially as described and
represented.
In witness whereof, I, the said Alexander Browne, have here-
unto set my hand and scal, this Tenth day of December, in
the year of our Lord One thousand eight hundred and seventy-
three.
