Improvements in Axles and Axle Boxes for Railway Rolling
Stock.
I, EDWARD BOND BAKER, of Suffolk House, Laurence Pountney Hill, in the
City of London, Gentleman, do hereby declare the nature of this invention 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 the construction of axles and axle boxes for railway
rolling stock in such a manner as to ensure continuous and effective lubrication and
to prevent waste of the lubricant.
For this purpose I provide at the end of the axle an appliance by which lubricant
is constantly raised from the space in the box below the axle, and delivered on to
the axle, this appliance being either a wiper revolving with the axle, or a chain
passing over a pulley attached to the axle and revolving with it.
Fig. 1 of the accompanying drawings is a longitudinal section, Fig. 2 is a plan
and Fig. 3 a transverse section on X X Fig. 2 of an axle provided with a wiper,
Fig. 4 is a part longitudinal section and Fig. 5 a part transverse section shewing
the pulley and chain for lubrication.
Referring first to Figs. 1, 2 and 3, the axle A has fixed on its end by screws Ca
wiper B, which is a piece of plate of segmental form bent at its end as shewn in
Fig. 1 so as to extend quite over the axle collar, or not so far as indicated by the
dotted lines. The axle box D has in its front a recess E giving space in which the
wiper B can freely revolve, and at its back a recess N; its bottom part F forms a
reservoir for lubricant supplied at Q, and is preferably divided into two com-
partments by a perforated partition P.
The bearing J may have at its front projections indicated by the dotted lines H,
to aid in directing along the bearing lubricant raised by the revolving wiper and
delivered on the collar and front of the bearing. The hind collar of the axle has
grooves L turned in it with ridges M between them, from which lubricant instead
of passing towards the dust guard is thrown off by centrifugal force, the lubricant
descending the walls of the recess N to the reservoir F whence it is again raised by
the wiper.
Referring now to Figs. 4 and 5 in which parts corresponding with those in
Figs. 1, 2 and 3 are marked by similar reference letters, a pulley R is fixed by
screws C on the end of the axle, and this pulley carries a chain S which dips into
the lubricant in F and as it revolves with the axle carries lubricant up delivering it
on the front and collar of the axle.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. In combination with the axle of a railway vehicle an appliance such as a
wiper or chain which as it revolves with the axle dips into lubricant in the axle box
and raises portions thereof which it delivers on the collar of the axle and the front
of the bearing, substantially as and for the purposes set forth.
2. For an axle having a lubricating appliance such as is above referred to, an
axle box recessed and partitioned, substantially as described.

the purpose set forth.
