page_text: LETTERS PATENT to William Robert Lake, of the Firm of Haseltine,
Lake, & Co., Patent Agents, Southampton Buildings, London, for
the Invention of "IMPROVEMENTS IN JOURNAL OR AXLE BOXES."-A com-

PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition,
on the 15th May 1873.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
Patent Agents, Southampton Buildings, London, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN JOURNAL OR AXLE BOXES,"
à communication, to be as follows:-
This Invention relates to journal
or axle boxes for railway carriages,

page_text: movement of the journal in its box being by this Invention converted
into a movement of the equalizer or carriage bearing upon its seat.
Second. In the arrangement of lubricating devices with a perforated
lubricating cylinder.
And third. In the construction of the axle box in sections, with 1
sliding connections.
The lower section of the box constitutes an oil holder, and it tapers
from each side to a narrow channel at the base, within which rotates a
perforated oil-distributing cylinder. The journals of the said cylinder
are seated upon spring bearings, which serve to keep it always in contact
with the under side of the carriage wheel journal.
Within the upper section of the box are located the bearing rollers;
they are usually made of equal diameter with the wheel journal, and
provided with elongated journals to give the lateral play required by the
longitudinal shifting of the journal in the box.
Externally the said box is provided with journals, having their axis of
rotation at right angles with and a little above the axis of the wheel
journal. It is also provided with a convex bearing seat, concentrically
arranged above each of the said journals by a shoulder face. Between
these convex seats is arranged a rise or convex rib, which acts as a stop
to keep the bearing block from sliding longitudinally from the seat.
Hook connections are used to secure the sections of the box together, a
latch being employed to screen them.
The bearing block has a concave bearing face at each end, and a slot
or other device on the upper surface to receive the end of the equalizer
bar or carriage bearing proper, a cleft or recess being left between the
bearings to receive the stop ridge.
Immediately within the orifice through which the journal enters the
box are broad flanches, which embrace the journal. A channel extends
around the inner surface of the flanches to guide the surplus oil back
into the oil chamber through the perforation leading to the inner journal
of the oil cylinder. The upper section of the box is a strong casting,
and is provided inside with slightly concave bearing faces, against which
the antifriction rollers move in their revolution.

filed by the said William Robert Lake in the Great Seal Patent
Office on the 14th November 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of May, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Robert Lake, Her special
Licence that I, the said William Robert Lake, my executors, adminis-
trators, and assigns, or such others as I, the said William Robert Lake,
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
"IMPROVEMENTS IN JOURNAL OR AXLE BOXES," a communication to me from
abroad by Russell Brewer, of the City and State of New York, United
States of America, Merchant, upon the condition (amongst others) that
I, the said William Robert Lake, 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.
NOW KNOW YE, that I, the said William Robert Lake, do hereby
declare the nature of the 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
Drawing, forming a part of this Specification:-
This Invention relates to journal or axle boxes for railway carriages,
and it consists,―
First. In the construction and novel arrangement of devices, whereby
the boxes are rendered steady upon the journals, the usual grinding ·

page_text: Secondly. In the arrangement of lubricating devices with a perforated
lubricating cylinder.
And thirdly. In the construction of the axle boxes in sections, with
sliding connections.
DESCRIPTION OF THE DRAWING.
Figure 1 is a vertical section, and Figure 2 a horizontal section of this
Invention.
A is the carriage wheel journal; B, the lower section of the box C.
This lower section constitutes an oil holder, and it tapers from each side
to a narrow channel at the base, within which rotates a perforated oil-
distributing cylinder D. The journals of the said cylinder are scated
upon spring bearings, which serve to keep it always in contact with the
under side of the said journal.
Within the upper section E of the box are located the bearing
rollers a, usually made of equal diameter with the journal A, and pro-
vided with elongated journals to give the lateral play required by the
longitudinal shifting of the journal A in the box.
Externally the box C is provided with the journals b, having their
axis of rotation at right angles to and a little above the axis of the
journal A. It is also provided with a convex bearing seat c, concentrically
arranged above each journal 6 by a shoulder face d. Between the
convex seats c is arranged a rise or convex rib e, which acts as a stop to
keep the bearing blocks from sliding longitudinally from the seat. The
hook connections, by means of which the sections of the box are secured
together, are shewn at m, a latch n being employed to screen them.
G represents the bearing block, having a concave bearing face i at each
end, and a slot or other device on the upper surface to receive the end
of the equalizer bar or carriage bearing proper, a cleft or recess being
left between the bearings to receive the stop ridge. The journals 6 aro
designed to play up and down in the slots of tho pedestal, and to have a
free rotary movement therein, while the bearing block G has a free
movement on the convex bearing seats c.
Should it be found in practise that the journal 6 will tend to wear in
the pedestal disadvantageously, a sliding seat may be introduced into the
pedestal slot to receive said journal.

page_text: Immediately within the orifice through which the journal A enters
the box are broad flanges, which embrace the journal. A channel r
extends around the inner surface of these flanges to guide the surplus oil
back into the oil chamber through the perforation 8, leading to the
inner journal of the oil cylinder. The upper section of the box is a
strong casting, and is provided inside with slightly concavo bearing
faces t, against which the antifriction rollers a move when in revolution.
Having thus fully described the said Invention, as communicated to
me by my foreign correspondent, and the manner of performing the
same, I wish it understood that I claim,-
First. The bearing block G, having concave bearing surfaces, or an
equivalent device, in combination with an axle box having convex
bearing seats, as herein specified.
Second. An axle box provided with journals b, arranged at right
angles with the carriage wheel journal, as herein specified.
Third. An axle box provided with journals at right angles with the
carriago wheel journal, and with convex bearing seats c concentric or
nearly concentric therewith, as herein specified.
Fourth. The axle box, consisting of an upper section and a lower
section, or oil reservoir, attached by sliding connections, and secured by
a latch or equivalent contrivance, as herein specified.
Fifth. The combination with an angle box having the concave bearings
and rotating oil cylinder D of the antifriction rollers a, as hercin
specified.
In witness whereof, I, the said William Robert Lake, have hereunto
set my hand and scal, this Fourteenth day of November, in the
year of our Lord One thousand eight hundred and seventy-
