COMPLETE SPECIFICATION filed by the said William Robert Lake at
the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 29th November 1869, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the "International Patent Office," Southampton
Buildings, London, Consulting Engineer, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS

page_text: LUBRICATING THE SAME," and have petitioned Her Majesty to grant unto
me, my executors, administrators, and assigns, Her Royal Letters
Patent for the same, and have made solemn Declaration that it has
been communicated to me from abroad by Isaac Pennington Wendell
and Stephen Paschall Morris Tasker, both of Philadelphia, Pennsylvania,
United States of America.
NOW KNOW YE, that I, the said William Robert Lake, do hereby
declare that the following Complete Specification, under my hand and
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 relates in the first place to a journal bearing for railway
carriages constructed with an oil chamber in the body of the bearing
and vertical tubes within the chamber, which tubes extend to the
wearing surface of the bearing, and are supplied with wicks or fibrous
cords, which lie in the bottom of the chamber, and pass into the tops of
the tubes and extend down the same to the face of the bearing with
their ends touching the journal. The main portions of the wicks lie in
the oil in the chamber, and are thereby well saturated with oil, the
latter passes through the wicks by capillary attraction, and supplies the
face of the bearing and the journal with oil as the latter revolves. The
upper ends of the tubes are higher than the surface of the oil in the
chamber to prevent a too rapid passage of the oil to the surface of
the bearing.
In the second place, the said Invention relates to recesses formed in
the face of the bearing at suitable distances apart with small openings
communicating with the said oil chamber, and filled with leather or
other porous material, whereby the oil is gradually brought to the
journal at different points on the face of the bearing, oozing gently
through the porous material as it passes through the small openings
leading thereto, so as to insure a proper distribution of the oil on
the face of the bearing and the periphery of the journal. When the
journal is in motion, if there were many of the oil feeding cords in the
bearings there would be too great a supply of oil to the journal, but
when there are but two, when the recesses and porous material are used
in conjunction with the cords, the oil may be supplied gradually enough,
and at the same time be evenly distributed. Under some circumstances

page_text: the tubes and cords may answer very well without the aid of the porous
material within the recesses, and the latter may in other cases answer
well without the tubes and cords.
Having thus stated the character of the said Invention, I will now
proceed to give a detailed description thereof, reference being had to the
accompanying Drawings making a part of this Specification, in which
Figure 1 is a plan or top view of the improved bearing adapted to a
railway carriage; Figure 2 is a vertical longitudinal section of the same
at the line a, b, of Figure 1; Figure 3 is a cross section at the line c, d,
of Figure 1; Figure 4 is a horizontal section at the line e, f, of Figure 2.
Like letters in all the Figures indicate the same parts.
A is the improved bearing whose upper surface is made of such form
as to conform to the surface of the journal box. The piece is cast with
a chamber B to contain the oil for lubricating the journal. The requisito
strength of the bearing is preserved by making its central part solid,
as represented in the Drawings. Other solid parts in the area of the oil
chamber may be made without decreasing too much the capacity of the
chamber. There are tubes or openings C which extend from the wearing
or concave surface a of the bearing to the upper part of the chamber. I
place cotton or woollen cords D, or other suitable material in the
chamber B and extend them through the tubes C.
In order to distribute the oil very evenly over the face of the bearing
and the journal, there are recesses c in the face a of the bearing which.
are filled with leather d, or compound of asbestos, plumbago, and paper
pulp, or other porous material, and leading from these recesses to the
chamber B are small openings e, through which the oil passes to the
porous material, and then gently oozes through the latter to the face of
the bearing. But two recesses c are shown in the Drawings, yet in
practice it may be well to have more distributed diagonally, so that an
oiled surface shall be presented to the whole length of the journal.
Having thus fully described the said Invention as communicated to
me by my foreign correspondents, and shewn how the same may be
conveniently and advantageously carried into practice, I claim,―
First. The journal bearing A constructed with an oil chamber B
and tubes or openings C, which are provided with a cord D or other
fibrous material, substantially in the manner and for the purpose herein-
before described.

page_text: Second. The recesses c and holes e communicating with the oil
chamber B, the said recesses being filled with a porous material,
substantially as and for the purpose set forth.
In witness whereof, I, the said William Robert Lake, have hereunto
set my hand and seal, this Twenty-ninth day of November, in t
the year of our Lord One thousand eight hundred and sixty-
nine.
WILLIAM ROBERT LAKE. (L.S.)
