Improvements in Means for Lubricating the Hubs of Wheels.
We, JOHN ARCHER SMITH, of 271, Southwark Bridge Road, Timber
Merchant, and JOSIAH CLEMENT CHANDLER, of 234, Kennington Park Road,
Engineer, both in the County of London, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to improvements in lubricating-hubs for the wheels of
velocipedes and other carriages the object being to provide a self contained and
independent oil chamber adapted to be inserted into and connected with the bub
proper.
Our oil container is constructed of a cylindrical or other suitably shaped chamber
adapted to slide and fit into the hub proper and is provided with a central sleeve
adapted to slide and fit over the spindle of the wheel.
The container is fixed in any suitable manner, such as by means of a screw, to
the hub, in which case it would revolve with the hub, or we may fix it to the
spindle and allow the hub to revolve free of the oil chumber. On the sleeve we fix a
short bell mouth tube having its top covered but provided with a small hole. The
bell serves as a receiver and collects a small quantity of the lubricant as the
chamber revolves and the said receiver being much larger below the hole the oil
sinks to the spindle and gets away to the ball bearings in the usual way.
Amongst the advantages derived from our improved hub for automatically
supplying bearings of wheels with oil may be mentioned :—
That the oil chamber is independent of the hub proper.
That the chamber can be easily removed from the hub proper and be as easily
replaced.
That the whole can be taken to pieces for cleaning if necessary.
That no charging hole is necessary through the hub proper.

We, JOHN ARCHER SMITH, of 271, Southwark Bridge Road, Timber
Merchant, and JOSIAH CLEMENT CHANDLER, of 234 Kennington Park Road,
Engineer, both in the County of London, 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 improvements in lubricating-hubs for the wheels of

page_text: velocipedes and other carriages the object being to provide a self contained and
independent oil chamber adapted to be inserted into, and connected with, the hub
proper.
The oil container is constructed of a cylindrical or other suitably shaped chamber
adapted to slide and fit into the hub proper and is provided with a central sleeve
adapted to slide and fit over the spindle of the wheel."
The container is fixed in any suitable mauner, such as by means of a screw, to
the hub, in which case it would revolve with the hub. On the sleeve is fixal a
short bell month tube having its top covered but provided with a small hole. The
bell serves as a receiver and collects a small quantity of the lubricant as the
chamber revolves and the said receiver being much larger below the hole the oil
sinks to the spindle and gets away to the ball bearings in the usual way.
In the accompanying drawing,
Figure 1 is at elevation of a lubricating-hub constructed according to this
invention:
Figure 2 is a longitudinal section of the same.
Figure 3 is a longitudinal section of the container.
a is the hub of the wheel, the spindle or axle passing through the same
and c, e the ball bearings upon which the hub rotates all of ordinary construction.
d is the cylindrical chamber of the oil container which is, as shewn clearly in
Figure 2, adapted to slide and fit into the hub a and e is the central sleeve of the
.container which passes through the chamber d and is adapted, as shewn in Figure 2,
to slide and fit over the spindle b, of the wheel. In the drawing one end of
the sleeve e is shewn rigidly secured to one end d' of the container d, the Baid
sleeve e and end dheing secured in position by means of a nute screwed upon the
other end of the sleeve e which end projects through the chamber d, as clearly
shewn.
fis the short bell mouth tube fitted to the sleeve e, and f' is the cover of the
same the said cover being provided, as shewn, with a central hole ƒ³.
As above mentioned. the oil container can be secured by means of a screw or the
like or by other suitable means to the hub a of the wheel in which case it would
revolve with the said bub. When the wheel is revolving the bell serves as a
receiver and collects a small quantity of lubricant as it revolves and the said
receiver being much larger below the hole f, as shewn in the drawing, the oil
which passes into it sinks to the spindle b and passes to the ball bearings in the
usual manner.
Amongst the advantages derived from the use of this improved hub for
automatically supplying bearings of wheels with oil may be mentioned :-
That the oil chamber is independent of the hub proper.
That the chamber can be easily removed from the hub proper and be as easily
replaced.
That the whole can be taken to pieces for cleaning if necessary.
That no charging hole is necessary through the hub proper.
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. In lubricating-hubs for the wheels of velocipedes and other carriages the
employment of an oil container of suitable shape adapted to slide and fit into the
said hub and having a central sleeve with an outlet for the lubricant the said sleeve
being adapted to slide and fit over the axle or spiulle of the wheel substantially as
bereinbefore described.
2. A lubricating-hub for the wheels of velocipedes and other carriages con-
sisting of an external hub proper and an internal oil container fitting into the saine
and having a central sleeve adapted to fit over the axle of the wheel and being
provided with a bell month tube having e cover provided with a hala subotantialle
