I, HORMUSJEE MERWANJEE JAORAWALA, of Jaora, Central India, Merchant, do
hereby declare the nature of this invention and in what manner the same 18 to
be performed to be particularly described and ascertained in and by the following
statement.
-
My said invention relates to improvements in axle boxes Its object 18 to reduce
the friction between an axle and its bearing by using a single roller carried on
conoidal pivots above the axle The roller and the bearing end of the axle are
enclosed in a tight metallic case having a stuffing box at the point of issue of the
axle Oil 18 supplied to the pivots from lubricators fixed on the top of the case or
axle box and this oil when used falls into the bottom of the box and 18 preserved
for use.
In order that my said invention may be more clearly understood I will describe
it with reference to the accompanying drawings in which
Fig. 1 is a plan of an axle box constructed in accordance with my said invention.
Fig. 2 18 an end view of the same
Fig. 3 18 a longitudinal section.
Fig. 4 18 a transverse section
In all the figures the same letters refer to the same parts.
a 18 the axle b is the antifriction roller having conoidal journals c The anti-
friction roller b is made by preference not less than twice the diameter of the axle
and in the case of large sizes it may be cast hollow.
The journals c take into suitable recesses in the plates dd which are formed with
projecting cheeks entering into recesses at each end of the antifriction roller so
that should either or both the journals break the roller may still be held in
position
One of the supporting plates d has a gap at e to allow the passage of the axle
The other plate d is solid and carries a set screw ? which controls the end play of
the axle. This arrangement may be modified by forming gaps in both the plates d
so that the axle may traverse both plates In this case the set screw I will be
fixed in the door h.
The side plates d which have oil channels
the points of the journals are held in their
four bolts f having double nuts at each end
by preference of steel
to carry oil from the lubricators to
proper relative positions by means of
The side plates and roller are made
The axle box forms a tight case around the roller and axle The object of
the stuffing box at the point of issue of the axle is to prevent the escape of oil,
or the entry of dust.
Access is had to the box by the door h
My said invention is applicable to the axles of tramway railway and the like
carriages and by suitably arranging the relative positions of the antifriction
roller and the axle it may also be used for the shafts of fixed machinery.
