page_text: LETTERS PATENT to William Robert Lake, of the "International
Patent Office," Southampton Buildings, London, Consulting
Engineer, for the Invention of "IMPROVEMENTS IN AXLES AND AXLE
BOXES FOR WHEELED VEHICLES."-A communication from abroad by
Ernest Von Jeinsen and James Monroe McDonald, both of San
Antifoxin Tnited States of America. Gentlemen
PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition, on
the 2nd December 1870.
I, WILLIAM ROBERT LAKE, of the "International Patent Office,"
Southampton Buildings, London, Consulting Engineer, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN AXLES
AND AXLE BOXES FOR WHEELED VEHICLES," a communication, to be as
follows:-
:
The said Invention relates to certain improvements in axles and axle
boxes for wheeled vehicles, and is designed for excluding dust, retaining
the box on the axle, and thoroughly lubricating the various parts.

page_text: A
The said Invention consists in certain details of construction and
arrangement .herein-after fully described. The axle has a cylindrical
part, a collar, and a conical or taper part. The conical part of the axle
is provided with a longitudinal cylindrical oil passage concentric with or
parallel to the axis of this part of the axle, and extending from the end
of the axle to near the collar, where it joins a radial passage com-
municating with an annular recess or oil reservoir. The said oil reservoir
is filled by first revolving the wheel in which the box is placed until a
screw therein is uppermost, then removing the said screw, and pouring
in the oil. The top of the head of the screw may be flush with the
outer surface of the hub. Feathers are provided to prevent the turning
of the box on the hub. The box has a recess at its inner end into
which the aforesaid collar fits, and the inner side of the collar is flush
with the inner end face of the box. The box is kept from slipping off
of the axle by a plate which is firmly secured to the box by screws.
ring or rings of leather or india-rubber or both may be placed between
this plate and the box for the purpose of making an elastic joint and
allowing more end motion if required. The oil from the reservoir fills
the longitudinal oil passage, and through this passage fills any space
that may be between the end of the axle and the end of the box, the
oil being thus supplied. at or near both ends of the conical part will
find its way to every part of the surface of the said part; the slight
endlong or jarring motion of the parts will drive the oil with violence
into any space that may exist between the axle and the box, and will
also force the oil with more or less violence back and forth through the
oil passages and prevent the choking or stopping of such
passages, and
provide a constant and effective means for the lubrication of all of the
parts. A cap is secured to the wood of the hub by means of nails or
screws passing through holes. These holes may be countersunk on the
outside for receiving the heads. This cap makes a neat finish for the
outer end of the hub.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of December, in the
year of our Lord One thousand eight hundred and seventy, in the
thirty-fourth-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 AXLES AND AXLE BOXES FOR WHEELED VEHICLES," a com-
munication to me from abroad by Ernest Von Jeinsen and James
Monroe McDonald, both of San Francisco, California, United States of
America, Gentlemen, upon the condition (amongst others) that I, the
said William Robert Lake, my executors or administrators, by an instru-
ment 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.
The said Invention relates to certain improvements in axles and
axle boxes for wheeled vehicles; and is designed for excluding dust,
retaining the box on the axle, and thoroughly lubricating the various
parts.
The said Invention consists in certain details of construction and
arrangement herein-after fully described.

page_text: Figure 3 is an elevation, and Figure 4 a section of a cap for covering
the end of the hub of a carriage wheel in which this Invention is
employed.
A is the axle having a cylindrical part 1, a collar 2, and a conical or
taper part 3. The conical part of the axle 3 is provided with a
longitudinal cylindrical oil passage 4, concentric with or parallel to the
axis of this part of the axle, and extending from the end of the axle to
near the collar 2 where it joins a radial passage 5, communicating with
the annular recess or oil reservoir 6 of the box B. The said oil
reservoir 6 is filled by first revolving the wheel in which the box is
placed until the screw 7 is uppermost, then removing the screw, and
pouring in the oil. The top of the head of the screw may be flush with
the outer surface of the hub. 8, 8, are feathers for preventing the box
from turning on the hub. The box has a recess at its inner end, 'into
which the collar 2 fits, and the inner side of the collar is flush with the
inner end face of the box. The box is prevented from slipping from
the axle by the plate C, which is firmly secured to the box by screws 9.
A ring or rings of leather or india-rubber or both may be placed between
the plate C and the box for the purpose of making an elastic joint and
allowing more end motion if required. The oil from the reservoir 6 fills
the passage 4, and through the passage 4 fills any space 10 that may be
between the end of the axle and the end of the box; the oil being thus
supplied at or near both ends of the conical part 3 will find its way to
every part of the surface of this part 3, and the slight endwise or jarring
motion of the parts will drive the oil with violence into any space that
may exist between the axle and the box, and also force the oil with more
or less violence back and forth through the passages 4 and 5, preventing
the choking or stoppage of the said passages, and providing a constant
and effective means for lubricating all the parts.
The cap represented in Figures 3 and 4 is secured to the wood of the
hub by means of nails or screws passing through holes 11. The said
holes may be countersunk on the outside for receiving the heads. This
cap makes a neat finish for the outer end of the hub.
It will here be observed that in the construction of axles and boxes
not only is the amount of friction reduced by lessening the wearing or
bearing surfaces but the axle is much less liable to break near the collar
or shoulder, and is constantly supplied with lubricating material in the
oil-tight reservoir or box, which seldom need be replenished.

page_text: Having thus fully described the said Invention as communicated to
me by my foreign correspondents, I claim,—
First. Providing the axle A with a longitudinal oil passage 4 and
radial passage 5 as described and for the purpose set forth.
Second. In an axle and box for vehicles, the combination of the
recess or oil reservoir 6 and space 10 with the passages 4 and 5 arranged
as described and for the purpose of lubricating the wearing surface.
Third. Securing the plate O by screws 9 as described instead of by
long bolts passing through the wood or otherwise.
Fourth. The combination of the axle A as described with the box B,
plate C, and cap, Figures 3 and 4, substantially as and for the purpose
set forth.
In witness whereof, I, the said William Robert Lake, have here-
unto set my hand and seal, this First day of June, in the year
of our Lord One thousand eight hundred and seventy-one.
Witness,
E. W. TYNDALL.
WILLIAM ROBERT LAKE. (L.S.)
