We, SAMUEL CHANDLER Junior and JOSIAH CHANDLER, both of Central
Works, Kennington Oval, in the County of London, Gas Engineers, do hereby
declare the nature of this invention to be as follows:-
-
This invention relates to an improved method of lubricating the bearings of
bicycles and tricycles whereby the ordinary oil can is dispensed with and the
liability of dust and grit getting into the bearing precluded while the trouble
caused by the oiling process is reduced to a minimum.
According to our invention each axle passing through the hubs is hollow and
has a small hole or holes in or about the centre and to one end of the hollow axle
we attach a lubricating box with a movable head either screwed or otherwise.
This box is charged with the lubricating material before starting and if found
necessary to lubricate the axle on the road it is accomplished by simply turning
the box head which forces the lubricant into the bearing of the hub. It will be
obvious that, the lubricant being conducted from an enclosed box, grit or dust is
forced out from rather than into the bearing of the machine.

Improvements in Lubricating Cycles.
We, SAMUEL CHANDLER Junior and JOSIAH CHANDLER, both of Central
Works, Kennington Oval, in the County of London, Gas Engineers, 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 an improved method of lubricating the bearings of
bicycles and tricycles whereby the ordinary oil can is dispensed with and the
liability of dust and grit getting into the bearings precluded while the trouble
caused by the oiling process is reduced to a minimum.
According to our invention each axle passing through the hubs is hollow and
has a small hole or holes in or about the centre and to one end of the hollow axle
we advantageously attach a lubricating box with a movable head or cover either
screwed or otherwise. This box and the hollow axle are charged with the
lubricating material before starting and if found necessary to lubricate the axle on
the road it is accomplished by simply turning the hox head or cover which forces
the lubricant into the bearings of the hub. It will be obvious that, the lubricant
being conducted from an enclosed box, grit or dust is forced out from rather than
into the bearings of the machine.
To enable our invention to be fully understood we will describe how it can be
carried into practice by reference to the accompanying drawings, in which :-

chain driven safety bicycle provided with our improvements:

manner; or the box may be dispensed with, in which case a cap or a

By this construction if the box and the bollow axle are charged with lubricant
it will be obvious that in order to force the lubricant into the bearings b, bit will
only be necessary to turn the cover (or the cap or plug) as required.
Although we have described our invention in connection with the hub and axle
of the driving wheel of a chain driven safety bicycle it will be obvious that it is
equally applicable to the hub and axle of the steering wheel of the bicycle, or to
the hubs and axles of other velocipedes.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The herein described method of lubricating bicycles by forcing the lubricant
into the bearings from a hollow axle substantially as described.
2. A bicycle or other velocipede having a hollow axle in communication with
the bearings, the said hollow axle serving to receive the lubricant and being
provided with a movable head, cover, or plug for forcing the lubricant into the
bearings as herein before described and illustrated in the accompanying drawings.
3. The manufacture and use of a lubricating axle for velocipedes constructed as
hereinbefore described and illustrated in the accompanying drawings.
