Improvements in Ball Bearings for Velocipedes and other Vehicles.
We, WILLIAM GEORGE PRICE and JOHN ENOCH NAGLE, both of 23 to
29, Frodsham Street, Chester, Cycle 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 :-
Our invention relates to improved means for locking or securing the adjustable
cones or ball cups used in ball bearings of cycles and other vehicles. Such cups or
cones as at present employed usually screw into the hub or equivalent part adapted
to receive them, which is formed with an internal thread for that purpose, such
thread being of reverse direction on opposite sides of the wheel or pedal on which
they are fitted.
According to our invention all such cups or cones are provided with the same
thread, namely a right-handed thread, irrespective of the side of the bearing of
which they form part, and are thus interchangeable with each other.
The means for securing such cups or cones when adjusted within their hubs or
equivalent parts, consists primarily of a locking nut or follower having the same
thread as the cup or cone which it locks, and which screws into the hub mouth or
equivalent part and abuts against the rear of such cone. The back of the cone is
provided with a neck or shoulder which projects through an aperture formed in the
locking nut, such neck or shoulder being threaded with a left hand thread and
adapted to receive a second locking nut. The function of this second locking nut
is to abut against and lock the first mentioned lock-uut, and so doubly secure
the cone.
In a rear driven bicycle the cones and each pair of locking nuts are identical for
each hub, with the exception of the secondary locking nut on that side of the rear
hub upon which is screwed the chain or sprocket wheel, which nut is of larger
diameter in order that it may also lock such wheel in its position, together with
the cone or cup, such chain wheel being screwed onto the hub with a right hand
thread.
In the drawing bereto annexed
Fig. 1 is a sectional elevation shewing the application of our invention to the hub
of a wheel.
Fig. 2 is an end view of the hub shewn in Fig. 1, with the second locking nut
removed.
Fig. 3 is a view of the second locking nnt.
Figs. 4 and 5 are elevation and end view shewing the application of our invention
to the hub of a rear or driving wheel of a cycle.
With reference to the drawings, a a denote the ball cups or cones of the hub,
said cups being screwed into the mouths bb of the hub. cc are the primary lock-
nuts of our invention, which also screw into the mouths bb, bcth cones and lock-nuts
being provided with a right hand thread. dd are the secondary lock nuts of our
invention, which screw onto the necks ee of the cups a a with a left hand thread.
Both primary and secondary lock nuts are provided with holes ff to receive a key,
whilst flats g g are formed on the necks ee of the cups aa, by which the latter may
be adjusted.
It will be seen upon reference to the drawings that the primary and secondary
lock-nuts c and d provide a double security against the possibility of the cones a a
rotating when once they have been adjusted and locked.

page_text: Figs. 4 and 5 shew the application of our invention to the hub of a driving wheel,
the only difference with reference to the front hub, being that the locking nut d
next to the chain wheel h is of larger diameter, so as to abut against and lock such
chain wheel upon the hub to which it is screwed. The primary lock nut c may
sometimes be dispensed with in this application.
We would have it understood that although we have more particularly described
our invention as applied to the wheel hubs of cycles, the invention is equally
applicable to all ball bearings, such as the bottom bracket, pedals, or steering head.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
:-
1. The employment, for the purpose of securing the ball cups or cones of ball
bearings, of locking nuts having the same thread as the cups themselves. and
arranged to screw into the mouth of the hub or equivalent part in which they are
fitted and abut against such cups,, in combination with secondary locking nuts
provided with a thread of opposite direction to that of the cones and first mentioned
locking nuts, and arranged to screw onto a neck or shoulder formed upon said
cones and abut against said first mentioned locking nuts; arranged and operating
as herein set forth.
2. The employment, in ball bearings of cycles and other vehicles, of cones or ball
cups having the same thread irrespective of the side of the bearing into which they
are screwed, said cups being locked in position substantially in the manner herein
set forth.
3. The combination, arrangement, and disposition of parts forming means for
securing the cones or ball cups of ball bearings, substantially as.herein set forth.
4. The particular arrangement and disposition of parts herein set forth with
reference to the drawings.
