AN IMPROVED AUTOMATIC LUBRICATOR FOR THE AXLES OF CARRIAGES AND OTHER VEHICLES
Year: 1884

page_text: I RICHARD JAMES of Lowertown, Helston in the county of Cornwall, Farmer
do hereby declare the nature of the said Invention for "AN IMPROVED AUTOMATIC
LUBRICATOR FOR THE AXLES OF CARRIAGES AND OTHER VEHICLES," a communi-
cation to be as follows :—
The object of my invention is to provide a simple cheap and efficient lubricator
for the axles of carriages waggons and other vehicles..
In carrying out my invention I form holes or perforations in the axle-box,
extending longitudinally from the outer extremity and opening into the interior of
the said axle-box the inner extremities of the said holes or perforations opening
into the interior of the axle-box at various points throughout its length. A well
or reservoir for containing the oil is detachably secured upon the outer extremity
of the axle-box by a screw and the oil in the said well or reservoir being kept at
a bigher level than the inner ends of the holes or perforations in the axle-box, the
revolutions of the wheel cause the oil to be distributed through the said holes or
perforations to different points of the arm of the axle. The oil-well or reservoir is
provided with a hole at its outer extremity for the introduction of the oil and a
collar washer working over a collar on the axle, is secured to the inner side of the
nave of the wheel, with as many screws as are required, for the purpose of
preventing the entrance of dust into the axle-box.

I RICHARD JAMES of Lowertown; Helston in the county of Cornwall, Farmer
do hereby declare the nature of the said invention for "AN IMPROVED AUTOMATIC
LUBRICATOR FOR THE AXLES OF CARRIAGES AND OTHER VEHICLES (a communi-
cation) 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 object of my invention is to provide a simple, cheap and efficient lubricator
for the axles of carriages wagons and other vehicles.
In carrying out my invention I form holes or perforations in the axle-box
extending longitudinally from the outer extremity and opening into the interior of 1
the said axle-box, the inner extremities of the said holes or perforations opening.
into the interior of the axle-box at various points throughout its length. A well
.or reservoir for containing the oil is detachably secured upon the outer extremity
of the axle-box by a screw and the oil in the said well or reservoir being kept at
.a higher level than the inner ends of the holes or perforations in the axle-box, the
revolutions of the wheel cause the oil to be distributed through the said holes or
perforations to different points of the arm of the axle. The oil-well or reservoir is
provided with a hole at its outer extremity for the introduction of the oil, and a
collar washer, working over a collar on the axle, is secured to the inner side of the
nave of the wheel, with as many screws as are required, for the purpose of
preventing the entrance of dust into the axle-box.
DESCRIPTION OF THE DRAWING.
Figure 1 is a side elevation of my improved lubricator.
Figure 2 is a longitudinal section of the same.
Figure 3 is a section of the same on the line x figure 1,
Figure 4 is a view of the outer end of the axle-box.
Like letters indicate like parts throughout the drawing.
A is the axle, A' is the arm or, spindle and A"! is the collar on the said axle.
a is the hole for the linch-pin. B is the axle-box. In the said axle-box I form
boles or ducts b extending longitudinally from the front, or outer end of the axle- &
box and opening into the interior of the same at various points throughout its
length. The axle-box shown in. the drawing has three such holes or ducts, one
opening into the interior of the axle-box near its forward end, one at about the
centre, and the other near its rear or inner end.
C is a reservoir or well for containing the oil, the said reservoir being made with
a neck c to screw upon the outer extremity of the axle-box B as shown. The said
reservoir or well has a small hole c¹ in the centre of its outer end through which
the oil is introduced into the interior cavity or well c A supply of oil can thus
be kept in the cavity or well all above the level of the inner ends of the holes or
ducts b in the axle-box when the said holes or ducts are brought, by the revolution

page_text: of the wheel, into their lowest position, and thus by the revolution of the wheel
the oil is automatically distributed through the said holes or ducts b to the different
points of the arm or spindle A' of the axle at which the inner ends of the said
ducts open.
The reservoir C may be of the form shown in the drawing or the size and form
of the reservoir C may be varied, provided a supply of oil can be maintained
therein above the level of the inner ends of the ducts b as above described.
I provide a collar-washer D working over the collar A" on the axle. The said
collar-washer is screwed to the inner side of the nave of the wheel and prevents
the entrance of dust into the axle-box B.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
First: A lubricator for carriage and other axles in which the oil is automatically
fed or supplied to the axle from the nose or front end of the axle-box.
Second-In an automatic lubricator for carriage and other axles, an axle-box
with holes or ducts b substantially as set forth.
Third-In an automatic lubricator for carriage and other axles, the oil reservoir
or well C substantially as set forth.
Fourth-In an automatic lubricator for carriage and other axles, an axle-box B
with holes or ducts b in combination with an oil well or reservoir c substantially
as set forth.
Fifth-In an automatic lubricator for carriage and other axles, the combination
of the axle-box B, oil well or reservoir C and collar-washer D substantially as set
forth.
