page_text: I, THOMAS JONES Fitter, of 200 Pershore Road, Selly Park, Birmingham do
hereby declare the nature of this invention to be as follows:-
This invention relates to an improvement in connection with the hubs of cycle
wheels, and has for its object to provide a simple means by which the cup or ball
race may be securely locked in position.
In carrying out my invention I propose to form the outer face of the cup with
a sloping surface so that a projection is formed at one side, the surface sloping
in a spiral manner from the projecting point.
On the sleeve of the cup, which is preferably provided with two flat surfaces,
permitting a wrench to be applied, a small ring is fitted, the inner face of which
is formed in a corresponding manner to the face of the cup.
The two parts
will thus fit firmly together, and will engage with each other.
The ring and cup are both screw threaded externally, and are screwed into the
hub by means of a key inserted in two holes formed in the ring. The latter
owing to its peculiar shape forms a secure locking ring, and in order to render
it more effective the inner surface may be provided with a thin layer of soft
solder or other suitable material.

I, THOMAS JONES, Fitter, of 200 Pershore Road, Selly Park, Birmingham, 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 connection with wheel hubs and
like parts of cycles and has for its object to provide a simple means by which
the cup or ball may be securely locked in position.
to.
In the accompanying sheet of explanatory drawings to be hereinafter referred
Figure 1 is a sectional elevation of part of a cycle wheel hub fitted with my
cup or ball race locking device.
Figure 2 is an elevation of the cup and locking ring. Figure 3 is a plan of
the cup and Figure 4 a plan of the locking ring.

page_text: The same reference letters in the different views indicate the same parts.
In carrying out my invention I form the outer face of the cup A with a
sloping or inclined surface so that a projection as a is formed at one side, the
surface sloping in a spiral manner from such projection.
On the sleeve end A¹ of the cup A, which is preferably provided with two
flat surfaces, permitting a wrench to be applied, a lock nut or ring B is placed
having its inner face formed in a corresponding manner to the adjacent face of
the cup. The two parts will thus fit together, or will engage with each other.
The ring B and cup A are both screw threaded externally, and are screwed
into the hub by means of a key inserted in two holes formed in the outer face
of the ring, or in any other convenient manner. When the cup and ring are
screwed into the required position such as illustrated at Figure 1, the cup A is
held or prevented from rotation by a spanner or other suitable tool, whilst the
ring B with another tool is made to turn slightly in the reverse or un-screwing
direction with the result that the inclined inner face 6 of the ring will move
up the inclined adjacent face a of the cup A, and as the inclination of such
faces is greater than the inclination of the screw threads, both the cup and the
ring are securely fixed by the locking or jamb action produced by the inclined
plane between their adjacent faces whereby the two parts are forced away from
each other and their threads pressed tightly upon the internal threads of the
hub into which they are screwed.
I sometimes provide a thin layer of soft solder or other like material upon the
inclined faces of the cup A and ring B.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
1. The improved means for locking a ball bearing cup in position sub-
stantially as described.
2. A lock nut or ring having its under or bearing face of a spiral or inclined
form, such spiral or inclination being of a greater pitch than the pitch of the
screw thread on its exterior surface, substantially as described.
