PROVISIONAL SPECIFICATION.
Improvements in Ball Bearing Hubs for the Wheels of Velocipedes,
and the like Vehicles.
I, GEORGE TOWNSEND, of Aston Cantlow Mills, Alcester, in the. County of
Warwick, Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to an improvement in ball bearing hubs for the wheels of
velocipedes and the like vehicles, and it consists of an improved method of locking
the cups or cones threaded into the ends of the hub, one of which cups or cones is
adjustable for the purpose of compensating for wear.
The non-adjustable cup or cone is threaded into the end of the hub by a left-
handed thread and is locked thereto by means of a nut having a left-
hand thread which is screwed on to the cup or cone and bears against the end of
the hub. The adjustable cup or cone is threaded into the other end of the bub by a
right-hand thread and it is locked by means of a right-hand threaded nut screwed
thereon and abutting against the end of the hub. The exterior of this end of the
hub is threaded with a left-hand thread on which is mounted a lock nut adapted to
be locked back into contact with the right-hand threaded nut on the cup or cone.
The nuts and lock nuts are preferably of the milled edge type, and are also provided
with one or more cross slots or holes to enable then to be operated by means of
a pin spanner.

I, GEORGE TOWNSEND of Aston Cantlow Mills, Alcester, in the County of Warwick
Manufacturer, 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 improvement in ball bearing hubs for the wheels of

the cups or cones threaded into the ends of the hub, one of which cups or cones is

page_text: The accompanying drawing is a view in front elevation partly in section of a hub
constructed according to this invention.
The non-adjustable cup or cone A is threaded into the end of the hub X by a left-
hand thread and is locked thereto by means of a nut B having a left-hand thread
which is screwed on to the cup or cone and bears against the end of the hub. The
adjustable cup or cone C is threaded into the other end of the hub X by a right-hand
thread and it is locked by means of a right-hand threaded nut D screwed thereon
and abutting against the end of the hub. The exterior of this end of the hub
is threaded with a left-hand thread on which is mounted a lock nut E adapted to be
locked back into contact with the right-hand threaded nut on the cup or cone. The
nuts and lock nuts are preferably, though not of necessity, of the milled edge type,
and are also provided with one or more cross slots or holes to enable them to be
operated by means of a pin spanner.
Having now particularly described and ascertained the nature of iny said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
An improved method of mounting and locking the cups or cones of ball bearing
hubs, consisting in threading the non-adjustable cup or cone into one end of the
hub by means of a left-hand thread and locking the said cup or cone by means of a
left-hand nut threaded on to the cup or cone and adapted to bear against the end
of the hub, in threading the adjustable cup or cone into the other end of the hub
by means of a right-band thread and locking the said cup or cone by means
of a right-hand nut threaded on the said cup or cone and adapted to hear against
the end of the hub, and in threading on the end of the hub into which the adjust-
able cup or cone is threaded a left-hand nut adapted to be locked back against
the right-hand nut on the adjustable cup or cone, as herein set forth.
