do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE CONSTRUCTION OF AXLE BOXES,” to be as follows :---
This Invention relates to certain improvements in the construction of
axle boxes applicable to the axles of wheeled vehicles, and whereby the
perfect and continuous lubrication of the same is effected in a simple
manner.

page_text: The axle box is constructed of an elongated cylindrical form, with one
or more tubular chambers attached to or formed in the mass of metal
of which the axlo box is constructed; such chambers being placed in
connection with the cylindrical portion of the axle box, and properly
closed at either end so as to prevent any escapo of the lubricating 5
material employed. Each end of the axle box is provided with a cap
capable of being fixed in position by means of pins, and provided with

page_text: NOW KNOW YE, that I, the said Edward Davis, do hereby declaro
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 annexed Drawings, and
to the figures and letters marked thereon, that is to say :—
My said Invention relates to certain improvements in the construction
of axle boxes applicable to the axles of wheeled vehicles of various
kinds, and whereby the perfect and-continuous lubrication of the same is
effected in a simple and advantageous manner..
The axle box is of an elongated cylindrical shape, with one or more
´tubular chambers attached to or formed in the mass c of metal of which
the axle box is constructed, the interior of such chamber or chambers
being placed in communication with the cylindrical portion of the axle
box, and being properly closed at either end so as to prevent any escapo
of the oil or other lubricating material employed. Each end of the axle
box is provided with a cap, which is capable of being fixed in position
by means of pins or other suitable contrivances, and provided with
apertures through which the oil or other lubricating material can be fed
to the axle.
•
Any suitable kind of metal may be employed for the construction of
the axle boxes.
I will now proceed to refer to the annexed Drawings, from which the
nature of my said Invention will be more clearly understood.
Figure 1 is a view in elevation of an axle and axle box constructed in
accordance with my said Invention. A is the axle; B, the axle box ;
and D, D, the caps at the ends of the same.
Figure 2 is a longitudinal section shewing the axle at A. The axle
box is shewn at B, and the tubular chambers at C, C, the caps being
shewn at D, D. The oil or other lubricating material is introduced at
the aperture, which is ordinarily closed by the screw d.
Figure 3 is a transverse section of the axle box and tubular chambers.
Having thus declared and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I would observe in
conclusion that what I consider novel and original, and therefore claim
as constituting the Invention secured to me by the said herein-before

page_text: in part recited Letters Patent is, the construction of axle boxes as and
for the purpose herein-before substantially set forth and described, or
any mere modifications thereof.
In witness whereof, I, the said Edward. Davis, have hereunto set
my hand and seal, this Seventeenth day of April, in the year of 5
our Lord One thousand eight hundred and seventy-two.
any mere modifications thereof.
