PROVISIONAL SPECIFICATION.
Improvements in Lubricating Cycles.
We, SAMUEL CHANDLER, Junior, and JOSIAH CHANDLER, both of Central
Works, Kennington Oval, in the County of London, Engineers, do hereby declare
the nature of this invention to be as follows:-
This invention relates to an improved arrangement for lubricating cycles.
In carrying out our invention we provide around the hub of the wheel a reservoir
for lubricant by means of a jacket arranged around the hub, the space between the
hub and jacket forming the said reservoir in which is placed either a semi-solid or
a liquid lubricant. Communication between the jacket and the bearings is effected
by means of small holes through the hub proper or by means of a tube or tubes
attached to the inside of the jacket.

Improvements in Lubricating Cycles.
We, SAMUEL CHANDLER, Junior, and JOSIAH CHANDLER, both of Central
Works, Kennington Qval, in the County of London, 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 arrangement for lubricating cycles.
In carrying out our invention we provide the hub of the wheel with a reservoir
to receive a semi-solid or a liquid lubricant, the said reservoir being formed either
by hollowing the hub and screwing it on to a sleeve for receiving the axle, or by
placing a jacket around the ordinary hub. Communication between the reservoir
and the bearings is effected by means of a hole in the hub or by a tube or tubes or
by means of a wick or wicks passing through a tube or tubes in the reservoir and
extending through a hole or holes in the hub.
To enable our invention to be fully understood we will describe it by reference
to the accompanying drawing, in which :-
Figure 1 is a longitudinal section of a hub (shewn applied to the axle of a cycle)
constructed according to our invention and shewing the arrangement wherein the
hub is formed hollow and screwed on to a sleeve the lubricant being fed to the axle'
through à hole in the sleeve.
Figure 2 is a longitudinal section of a hub similar to that shewn in Figure 1 but
provided with a tube for feeding the lubricant to the axle.
Figure 3 is a longitudinal section in which the reservoir is formed by a jacket
around the hub, and provided with tubes and wicks for feeding the lubricant to the
axle, and,
Figure 4 is a longitudinal section of a hollow, hub provided with tubes similar to
those shewn in Figure 3 but without wicks.
Similar letters in all the figures represent similar or corresponding parts.

page_text: In the several figures a is the hub, 6 the axle, c the ball bearings and d the chain
wheel all of ordinary construction.
In the arrangement shewn in Figure 1, the reservoir e for the lubricant is
formed in the hub a, the hub being screwed on to the sleeve which receives the
axle b; g is a hole in the sleeve through which the lubricant passes from the
reservoir e to the axle b; is a filling hole closed by a cap i.
The arrangement illustrated in Figure 2 is substantially the same as that shewn
in Figure 1, except that the lubricant passes from the reservoir e to the axle b
through the tube g'.
Figure 3 illustrates the arrangement where a jacket j is placed around the hub a
thereby forming the reservoir e for the lubricant which is introduced as before
through the filling hole h.
k, kare the tubes fixed to the jacket j one end of each tube being bent inwards
towards the axle b and fitting into holes in the hub a the other end of each tube
opening into the reservoir e."
1, are wicks inserted in the tubes k, k one end of each wick just touching the
axle 6 and the other end dipping in the lubricant in the reservoir e.
In the modification shewn in Figure 4 the wicks are dispensed with and the
reservoir e is formed by a jacket j which consists of a cylinder formed in two parts
and connected to the inner faces of the flanges m, m of the hub a the lubricant
being fed to the axle through the tubes k, k.
By the above described arrangements it will be obvious that as the axle revolves,
the lubricant will be automatically fed to it in a regular and even manner, and in
cases where the machine may be laid on its side no lubricant will be able to pass
from the reservoir it being understood that the reservoir is never to be quite filled
with lubricant.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. A hub for automatically lubricating the axles of cycles wherein the lubricant
is contained in a reservoir within or around the hub and is fed to the axle either
directly through holes in the side of the reservoir surrounding the axle or through
tubes, or by means of wicks in tubes, substantially as described.
2. A hub for automatically lubricating the axles of cycles having a reservoir e
for the lubricant formed within the hub a itself and provided with a hole or holes g
through which the lubricant is fed to the axle, substantially as described and
illustrated in Figure 1 of the accompanying drawing.
3. A hub for automatically lubricating the axles of cycles, having a reservoir
for the lubricant, formed within the hub a and provided with a tube g¹ through
which the lubricant is fed to the axle substantially as described and illustrated in
Figure 2 of the accompanying drawing.
4. In hubs for automatically lubricating the axles of cycles the combination with
the hub of a jacket having a filling hole h, wick tubes and wicks l, the said wick
tubes passing through holes in the hub the several parts being arranged and
operating, substantially as described and illustrated in Figure 3 of the accompanying
drawing.
5. The modified construction described and illustrated in Figure 4 of the
drawing.
6. The manufacture and use of the improved hubs for automatically lubricating
the axles of cycles herein before described and illustrated in Figures 1, 2, 3 and 4
respectively of the accompanying drawing.
