Improvements in Journal Lubricators.
I, JOSEPH THOMAS KERBY, of 63 Margaret Street, Cavendish Square, in the County
of Middlesex, Railway Contractor, do hereby declare the nature of this invention,
and in what minner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
The object of this invention is to provide a lubricating device for journals which
will be simple, cheap and effective, and which may be readily applied to journal boxes
already in use.
Figure 1 of the accompanying drawings represents a longitudinal section of a car
axle-box containing this improved lubricator.
Figure 2 represents a transverse section of said axle-box on line 1-1 of Figure 1.
Figure 3 is a perspective view of the wick-holder for holding the capillary wick in
contact with the journal.
Similar numerals of reference indicate corresponding parts in the different
figures.
This improved lubricator comprises a wick-holder 10 and a flat capillary
wick 20.
The capillary wick consists of a sheet of asbestos felt, woollen felt or other suitable
material.
The wick-holder consists of a base L1, spring arms 12 extending upwards therefrom
and curved jaws 13 at the upper ends of said arms. Each of the curved jaws is
provided with short spurs 14 which project upward and corresponding spurs 15
which project downward. Each jaw is also preferably provided with a transverse
slot 16 near its upper end and with a similar transverse slot 17 a short distance
below the upper slot. The spurs 14 in this construction extend upward and inward
from the upper edge of the intermediate bar 18 between the slots, and the spurs 15
project downward aud inward from the lower edge of said bar. The spring holder
may be stamped out from sheet-metal in one piece and afterwards bent into the
form shown.
In the drawings the lubricator is shown as applied to an ordinary car axle-box 30,
in which case the base of the wick-holder extends across the lower portion of the
axle-box and the spring arms are of sufficient length to bring the curved jaws opposite
the lower face of the journal 40. The upper ends of the wicks are engaged by the
spurs on the curved jaws and gently pressed by said jaws under the tension of the
spring arms against the journal and serve to paint the oil on to the journal as the oil
is drawn up by capillary attraction.
The spring wick-holder may be of any suitable width. The oil may be filled into
the journal-box through a duct in its outer end closed by a lid or through the ordinary
lid opening.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. A wick-bolder for a journal-lubricator consisting of a base, two spring arms
extending upwardly therefrom and curved jaws at the upper ends of said arms.
2. A wick-holder for a journal-lubricator consisting of a base, two spring arms
extending upwardly therefrom and slotted curved jaws at the upper ends of said
arms.
3. A wick-holder for a journal-lubricator consisting of a base, spring arms extending
upward therefrom and curved jaws at the upper ends of said arms, said jaws being
provided with spurs.

page_text: 4. A wick-holder for a journal-lubricator consisting of a base, spring arms
extending upward therefrom, and slotted curved jaws at the upper ends of said arms,
said jaws being provided with spurs.
5. The combination of a journal-box, a capillary wick and a wick-holder for said
wick, said wick-holder being composed of spring metal in one piece and comprising
a base, arms extending upward therefrom and curved jaws at the upper ends of
said arms.
6. The combination of a journal-box, a capillary wick and a wick-holder for said
wick, said wick-bolder being composed of spring metal in one piece and comprising a
base, arms extending upward therefrom and curved jaws at the upper ends of said
arms provided with transverse slots and spurs.
Dated this 23rd day of January 1890.
