Improvements in Railway Carriage and Wagon Axle-boxes.
1, EDWARD BEST, of Carleton Place, in the County of Lanark, in the Province of
Ontario, and Dominion of Canada, Machinist, do hereby declare 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:-
My invention which will be hereinafter fully set forth and claimed relates to devices
for lubricating the axles of railway-carriages and wagons.
The object of my invention is to provide an oiler for railway-carriage and wagon
axles that will work automatically giving a continuous and sufficient supply of oil to
the bearing as long as the axle is moving.
and
Referring to the drawings,
Figure 1 is a longitudinal section of my improved axle box.
Fig. 2 is a transverse section of the same.
Fig. 3 is an underside view of the removable top of the oil vessel.
Fig. 4 is a horizontal section on lineæ æ.
Figs. 5 and 6 show modifications of the construction of the axle box and oiler,
Fig. 7 is a cross section of the oiler shown in Fig. 6.
The outer casing A of the axle box is provided with grooves for the reception of the
sliding door B, which extends from the top to within a short distance of the bottom a
chain C is provided to prevent the door being removed or lost, this chain is attached
to lugs b and a cast integrally with the door B and outer casing A, a spring latch D
holds the door in place. This door B may be made in two pieces and extended down
to the bottom of the box as shown in Fig. 5 or hinged as shown in Fig. 6.
An opening is provided at the inner side of the box A for the entry and vertical
play of the axle, is the bushing and F the filler.
The oil vessel G is made preferably nearly the whole length of the bearing surface
of the axle, a projecting cup and screw cap are provided in front for filling the vessel,
the ends g are inclined and provided with cleats H on which rests the removable top 1,
having a concave surface J where it fits the axle and provided with perforations; the
edges of the concave portion J project slightly and perforations i are formed through
which any surplus oil finds its way back into the vessel, it has been found by experi-
ment that owing to the continual jarring of the axle boxes the oil at or near the
surface becomes considerably aerated and this impairs the suction power of the moving
surfaces, in order to obviate this an inverted trough is cast integrally with the top I
composed of the sloping sides K and the ends L, thus the oil for lubricating is taken
from near the bottom of the vessel G and completely prevents the induction of air.
These oiling boxes I prefer to make of cast metal but they may be made of hardened
rubber or other substance.
A strong spring M is provided to keep the oil vessel in contact with the axle, in Fig. 6
four of these springs are shown placed at the corners of the vessel.
My device operates as follows:-
The box is attached in the usual manner, and the oil vessel placed under the axle
and held thereto by the spring or springs, the oil is then placed in the vessel and the
door of the box closed, the revolving motion of the axle sucks up the oil which is
evenly distributed over the whole of the bearing surface of the axle.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-

removable, substantially as set forth.
2. An oil vessel for an axle box provided with a concave top having openings
therethrough for the emission and admission of the lubricant, substantially as set
forth.
3. An oil vessel for a railway carriage or wagon axle having its top formed with
the bearing surface adapted to be maintained in contact with the bearing surface of
the axle the said top being provided on its underside with a depending spout communi-
cating with the bearing surface of the top through opening substantially as set
forth.
4. A removable oil vessel for railway carriage or wagon axle boxes, having
attached to the under surface of its top side an inverted trough composed of the
downwardly and outwardly sloping sides K and L, substantially as set forth.
5. The combination with a railway carriage or wagon axle box of the removable oil
vessel G provided with cleats H the removable cover or top I, J, perforations ij, the
inverted trough K, L, and the spring M, substantially as set. forth.
