An Improvement in Ball Bearings.
I, TIES FONGERS of 219 and 220 Nieuwe Kerkhof, Groningen, Holland,
Manufacturer do hereby declare the nature of this invention to be as follows:-
My invention consists in introducing between the axle spindle or equivalent and
the hub of a wheel or its equivalent an intermediary loose sleeve or false hub of
such diameter as will enable it to ride clear of the axle, spindle or shaft. This
sleeve or false hub carries at each end double cups or cones one pair of which are
curved inwardly so forming the outward bearing or race for the usual ring of balls
which bear upon cones screwed on over ends of axle or shaft or on bearings
formed on shaft in any well known manner.
The upward or outwardly cupped portions of ends of loose sleeve form a second
lower or inner bearing for another set or ring of balls thus interposed between the
loose sleeve or false hub and the hub proper which is internally screwed to receive
at each end a coned cap shaped internally to form outer bearing or race for the
outer and extra tier or ring of balls.
I have described my invention more particularly as applied to the wheels of
cycles but it will be seen that with slight modification it may be used for pedals,
lower brackets, shafting, carriage wheels and various analogous purposes.

I, TIES FONGERS, of 219 and 220 Nieuwe Kerkhof, Groningen, Holland,
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 :-
My present invention consists of an improvement in ball bearings, by the use of
which friction is reduced to a minimum.
I will describe my invention more particularly as applied to velocipedes and
light vehicles, but it will be seen that with slight modifications, it may be used
for shafting (machinery), ordinary carriage wheels, and various analogous
purposes.
The accompanying sheet of drawings shows sections of my improved ball bearing
as applied to a velocipede,

Figure 2, a bottom bracket,
Figure 3, a front hub, and
Figure 4, a rear hub.
In Figure 3, are also shewn portions of the two

page_text: In carrying out my invention, I introduce between the spindle A or its equivalent
and the hub B of a wheel, pedal, or its equivalent, an intermediary loose sleeve
or false hub C of such diameter as will enable it to ride clear of the said
spindle A.
This sleeve or false hub C carries at each end double cups or cones, one of which
is curved inwardly, as at D, so forming the outer bearing or race for the usual set
or ring of balls E, said balls bearing upon cone A¹ screwed on over the ends of the
spindle A, or on bearings formed there on in any well known manner.
The upward or outwardly cupped portions F of the ends of the loose sleeve C
form a second lower or inner bearing or race for another set or ring of balls G
thus interposed between the loose sleeve or false hub C and the hub proper B,
which is internally screwed to receive at each end a coned cap or plate H or H¹,
shaped internally to form the outer bearing or race for the outer and extra tier or
ring of balls G before mentioned.
The cap H aforesaid (Figures 3 and 4) is made of sufficient size to render the
ball bearing as nearly as possible dust-proof, and I may extend the edge and cut
it into a series of notches J by which means the bearing may be adjusted and
locked by a pin or projection K (or more than one) fixed on the hub by a set
screw L, or any other like means may be employed for locking the plate in
position.
In order to economize space, and especially for use on the bottom bracket, I may
screw the plates or caps H₁ right into the hub on one or both sides without
providing any overlapping edge, and fix by means of a set screw M (or more than
one), holes N being made to facilitate unscrewing when necessary.
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 :-
A ball bearing consisting of a loose sleeve or false hub C surrounding the
spindle A, and provided at each end with a double race D F in which may work two
sets or rings of balls E G, the two inner rings or sets E bearing also upon cones A',
and the two outer sets or rings G bearing also upon coned caps or plates H H',
substantially as hereinbefore described and shewn on the accompanying sheet of
drawings.
