I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Charter Patent Agent, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object a double axle-box for carriages and vehicles
comprising two bearings for the axles which may be closed or open, and a hollow
space or chamber between said bearings which receives any suitable lubricating
material.
A hole closed by a screw plug serves for introducing the lubricant into the
hollow space or chamber.
In the interior of the chamber there are arranged one or more balls or rollers
which, under the influence of of the motion of the carriage roll about on the slightly
arched floor of the chamber thus forcing the lubricant into the bearings through
slots or passages formed between the lubricant chamber in axle bearings.
The lubricant which is contained in the chamber and lasts for several months
cannot become stiff and unfit for use owing to the constant motion of the balls.
The discharge of the lubricant from the chamber except under the influence of
the moving balls, is prevented by the special arrangement or form of the slots or
openings.
This invention seeks to effect the best utilisation and the smallest expenditure of
lubricant in the axle-boxes, at the same time reducing friction at the bearing sur-
faces to a minimum. Owing to this arrangement the axle boxes have to be sup-
plied with lubricant only at long intervals.
Dated this 8th day of November 1897.

Figures 4 and 5 are sections on the lines A B and C D Figure 2.
A hole c closed by a screw plug serves for introducing the lubricant into the
hollow space or chamber b.
In the interior of the chamber there are arranged one or more balls or rollers d
which, under the influence of the motion of the carriage roll about on the slightly
arched floor of the chamber thus forcing the lubricant into the axle bearings a a
through slots or passages e e formed between the lubricant chamber and the axle
bearings.
The lubricant which is contained in the chamber b and lasts for several months
cannot become stiff and unfit for use owing to the constant motion of the balls.
The discharge of the lubricant from the chamber except under the influence of
the moving balls, is prevented by the special arrangement or form of the slots or
springs e e.
This invention seeks to effect the best utilisation and the smallest expenditure
of lubricant in the axle-boxes, at the same time reducing friction at the bearing
surfaces to a minimum. Owing to this arrangement the axle boxes have to be
supplied with lubricant only at long intervals.
Having now particularly described and ascertained the nature of this invention
as communicated to me by my foreign correspondent and in what manner the
same is to be performed, I declare that what I claim is :-
1. A double axle-box for vehicles with automatic lubricating means whereby
the lubricating material is forced automatically and in a sufficient quantity into
the bearings by one or more balls or other rolling bodies contained in a hollow
chamber containing the lubricating material and communicating with the axle
bearings the balls rolling about under the influence of the motion of the carriage,
and preventing, at the same time, the lubricant from becoming stiff or unfit for
use, substantially as described.
2. The axle box for vehicles and means for lubricating the same substantially
as described and illustrated in the accompanying drawings.
Dated this 22nd day of July 1898.
