page_text: I, MAGNUS LEOPOLD JAMES HILLESTROM, of Ash Villa, Black Weir, Cardiff,
in the County of Glamorgan, Accountant, do hereby declare the nature of this in-
vention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to constructing railway carriage, wagon or other axle
boxes, and is specially arranged for those axle boxes that require oil for lubri-
cating the journals. The box itself has an opening in the front above the axle,
through which opening the bearing brass passes. The brass has a pair of
projecting flanges upon the sides, these flanges rest upon corresponding projec-
tions on the internal sides of the axle box, the top of the brass being made flat
and of large surface, upon which rests a removable oil chamber, which is a
rectangular casting which fits into an opening in the top of the axle box, after
the manner of a drawer, the oil box having an enlarged mouth-piece, carried
upwards to a certain extent above the front of the axle box, a suitable lid or cover
being provided at this part to facilitate supplying the oil chamber with oil.
Projecting tubes are formed at the bottom on the inside of the oil chamber, into
which tubes is inserted worsted or other absorbent material, for conveying the
oil by capillary attraction, from the oil chamber to the bearing below; oil holes
being made through the bearing brass immediately beneath the lubricating or
syphon holes before described, and leather or other washers, being inserted in a
recess in the top part of the brass to prevent the lubricating oil escaping between
the top of the brass and the bottom of the oil chamber. A suitable door or slide
is made in the top of the oil chamber, so as to facilitate access to its interior, for
renewing and adjusting the Syphon, supplying the oil and other arrangements.
The bottom of the axle box is closed in, and takes the form of a hollow cup,
secured in place by any convenient method. The object of this cup is to catch
and retain the oil that has run through from the oil chamber above, and thus
entirely prevents waste of oil.
To the hollow cup, or part forming the bottom of the axle box and which
retains the oil that has run through from, the oil chamber above, I attach an
arrangement for lubricating the under part of the journal, which consists of strips
of metal secured to the sides and bent round to come nearly in contact with the
under part of the journal as shown at in the drawings.
Upon these strips I place worsted or other similar material, the ends of which
hang down into the bottom of the oil cup or bottom of the axle box, the oil
lubricating the under part of the journal by means of the worsted becoming
saturated and which the journal rubs against when in motion.

page_text: To the suspended ends of these strips, I attach another strip, which runs in lin
with the journal for nearly its length, and on to this latter strip, I place a pad
which catches a portion of the oil and which assists as well as the worsted, it
thoroughly lubricating the journal.
A lubricating brush or swab, may be placed in the centre of the cup and
pressed upwards, by means of a spiral or other suitable spring, and which may be
used instead of the arrangement shown, for lubricating the under part of the
journal; but to this arrangement I attach no special importance.
A plug is placed in the bottom of the oil cup, so. that the oil may be drawn
away when necessary, the same oil being placed back in the oil chamber above,
if desired.
In the accompanying drawings:-
Figure 1 is a section of the axle box complete, at A B.
Figure 2 is a half elevation, of the front of the axle box, the other half being
a section at C D.
Figure 3 is half plan and half section of the axle box, through the oil chamber
or drawer containing the oil for lubricating the journal.
Figure 4 is a plan of the brass.
E is the main body of the axle box, and F is the opening at the top for placing
the brass in position on the journal and G is the rectangular drawer or oil chamber
having an enlarged mouthpiece, on to which is fitted a suitable lid or cover H. I
is a suitable slide or cover in the top of the oil chamber or drawer, provided to
get at the interior for renewing or adjusting the syphons when necessary.
The drawer, or oil chamber slides and fits into the top of the axle box, and is
secured in position by bolts, J, J, which may easily be removed when the drawer
is required to be taken out. K, K, are the projecting tubes, through which the
oil passes down, by means of the worsted arrangement L, the oil passing down
through the brass M, and on to the journal N. 0, 0, are leather washers, to
prevent the oil from escaping between the top of the bearing brass and the bottom of
the oil chamber. P is a groove cut in the bottom of the brass, into which the
oil runs to lubricate the whole length of the top of the journal. The brass M
rests on the journal, the flanges Q, Q, of the brass M being supported by correspond-
ing projections R, on the inside of the axle box.
S is the oil cup forming the bottom of the axle box, for containing the oil run
through from the oil chamber above.
T, T are the metal strips secured to the sides of the oil cup, and which are bent
round under and close to the bottom of the journal. U is the worsted, which is
supported on same, the ends of which hang down into the oil cup, the bottom of
the journal being lubricated by the action of the oil through the worsted, which
the journal rubs against when in motion..
V is another metal strip, suspended from the ends of the strips T, on which is placed
a pad which becomes saturated and assists in thoroughly lubricating the bottom
of the journal, and
W is a plug, temporarily secured in the bottom of the oil cup to facilitate the
release of the oil contained therein, when necessary.
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:
In an axle box, for supplying a liquid lubricant, of the type characterised by a
main casting or box proper having an opening in front above the level of the
axle, through which opening is inserted the bearing-brass and a removable drawer
for containing the supply of lubricant; the provision of wick-tubes and wicks
and top opening with sliding cover to the said removable drawer, the arrangement
consisting of strips of metal bearing an absorbent material and a pad adapted to
lubricate the under part of the journal, and the cup-like or concave bottom and

page_text: plug, adapted to catch the surplus oil and re-supply it to the bearing, all con-
structed, operated, and working substantially as herein described and set forth.
Dated this 20th day of July 1897.
