PROVISIONAL SPECIFICATION.
Improvements in and relating to Bearings for Velocipedes and the
like.
I, JOHN WILLIAM PARKER, of 27, Alexandra Road, West Kensington Park, in
the County of Middlesex, Mechanic, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to an improved device for locking the adjustable cups
or cones of ball bearings and as it has no exterior excrescence it is particularly
adapted for use with ball bearing hubs though it is also applicable to pedal-crank
axle brackets and the other bearings of velocipedes.
According to this invention the adjustable cup or cone is threaded externally
and is screwed into the hub, bracket or socket as the case may be, the outer end
of the cup or cone being reduced in diameter and the outer end of the hub,
bracket or socket being enlarged in diameter so that an annular recess is formed
by and between them the shoulders formed by the reduction and enlargement
respectively being bevelled or chamfered. In this annular recess is placed a
split or divided ring of copper or other ductile metal and in the enlarged end
of the hub, bracket or socket is threaded a ring having a coned or bevelled inner
face adapted to engage the soft metal ring which it squeezes up and jams between
the adjustable cup or cone and the hub, bracket or socket as the case may be,
the said ring being operated by means of a pin spanner or its equivalent engaging
holes in its outer face.
Improvements in and relating to Bearings for Velocipedes and the
like.
I, JOHN WILLIAM PARKER, of 27, Alexandra Road, West Kensington Park, in
the County of Middlesex, Mechanic, do hereby declare the nature of this inven-
tion 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 device for locking the adjustable cups
or cones of ball bearings and as it has no exterior excrescence it is particularly
adapted for use with ball bearing hubs though it is also applicable to pedal-crank
axle brackets and the other bearings of velocipedes.

page_text: In the accompanying drawing which illustrates two forms my invention may
assume:-
Figure 1 is a sectional view in end elevation of a pedal-crank axle bracket
showing the two cups locked by different methods, and
Figure 2 is an end view thereof with the threaded locking ring and washer
removed.
Throughout both views similar parts are marked with like letters of reference.
Referring to the left hand side of Figure 1, the adjustable cup or cone A is
threaded externally and is screwed into the bracket X or bearing case, the outer
end of the cup or cone being reduced in diameter and the outer end of the
bracket or bearing case being enlarged in diameter so that an annular recess Y
is formed by and between them, the shoulders formed by the reduction and
enlargement respectively being rounded, bevelled or chamfered.
In this annular recess Y is placed a split or divided ring B of copper or other
ductile metal and in the enlarged end of the bracket or bearing case is threaded
a ring C having a coned or bevelled inner face adapted to engage the soft metal
ring B which it squeezes up and jams between the adjustable cup or cone A and the
bracket X or bearing case, the said ring being operated by means of a pin
spanner or its equivalent engaging holes in its outer face."
A preferential construction is that illustrated by the right hand side of Figure 1
wherein the threaded locking ring C is made with a flat inner face instead of
being coned or bevelled and a washer C¹ is interposed between the inner face
of the ring C and the outer face of the soft metal ring B.
It will be understood that as usual one of the cups or cones may be fixed and
the other adjustable, and locked by either of the methods hereinbefore described
or both of the cups or cones may be locked by either of the above described
methods.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
(1) In a bearing for velocipedes or the like, locking the cups or cones by means
of a soft or ductile metal ring so arranged as to be adapted to be squeezed or
jammed to engage both the cup or cone and the bearing case.
(2) The improved bearing for velocipedes and the like constructed and arranged
substantially as hereinbefore described and sliown with reference to the left hand
side of Figure 1.
(3) The improved bearing for velocipedes and the like, constructed and arranged
substantially as herein before described and shown with reference to the right
hand side of Figure 1.
