page_text: I, AMOS FRANK SUDBURY TATHAM Belper Street Works Ilkeston Derbyshire, Lace
Manufacturer, do hereby declare the nature of this invention-to-be as follows:-
This invention relates to improvements in ball bearings, the object being to more
equally distribute the weight or wearing strain and at the same time in the case of a
bicycle or the like bearing enable an ordinary spindle to be used, and the same is
carried out as follows:-
Upon the outer ends of the hub or bearing supports I form a ball race or races in
which the balls run and caps having corresponding ball races are provided through
which the spindle passes.
The balls run between the races formed on the outer ends of the hub or bearing
and the caps aforesaid, said caps being secured in the required position by means of
lock nuts or other well known con renient means.
By this arrangement it will be seen that the spindle is quite free and the weight
and bearing strains are more equally distributed upon the balls.
Dated this 4th day of January 1897.

Improvements in Ball Bearings.
I, AMOS FRANK SUDBURY TATHAM Belper Street Works Ilkeston Derbyshire, Lace
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 improvements in ball bearings, the object being to more
equally distribute the weight or bearing strain and at the same time in the case of a
bicycle or the like bearing enable an ordinary spindle to be used, and the same is
carried out as follows:-
Upon the outer ends of the hub or bearing supports carried in same I form a ball
race or races in which the balls run and caps having corresponding ball races are
provided through which the spindle passes.
The balls run between the races formed on the outer ends of the hub or bearing
and the caps aforesaid, said caps being secured in the required position by means of
lock nuts or other well-known convenient means.
By this arrangement it will be seen that the spindle is quite free and the weight
and bearing strains are more equally distributed upon the balls,

page_text: In order that my invention may be fully understood, I will now refer to the annexed
drawings, in which :-
Figure 1. is a sectional view of my invention.
a is the spindle which carries the crank levers 6 which are secured in position by
means of the keys c or the like. The parts d having the grooves or ball races e upon
same in which the balls f run, the cap g is provided with corresponding ball races or
grooves h. The screwed end or boss i of the cap g engages in a screw thread in the
crank lever b.
By this arrangement it will be seen that the spindle a is of any ordinary
construction, and does not require to be specially screwed as the keying or fixing of
the crank levers upon the spindle a will ensure the adjustment of the grooves or ball
races or balls.
The, parts d are carried or secured to the bracket j or the like in any suitable
manner such as by the screw threads k upon same, being a lock nut for securing the
し
part in its adjusted position. The screw or bolt m is employed to secure the chain
driving wheel to the pedal crank lever. Of course it will be understood that any other
suitable ineans of securing the chain driving wheel to the crank lever or the like
may be employed. By this arrangement the wear and strains upon the bearing are
more equally distributed and at the same time the construction of same is greatly
simplified. The form of the grooves or ball races may be of any convenient and
suitable shape. Although for purposes of illustration I have shewn the ball bearing
in a form applicable to velocipedes, it will be seen that this form of bearing may be
employed for various purposes such as upon vehicles or machines.
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. The combined construction and arrangement of the various parts substantially
as and for the purpose set forth and illustrated herein.
:
2. In ball bearings a bearing part or parts having grooves or ball races upon its
outer end or surface, a cap having corresponding grooves or ball races and a screwed
boss which engages in a screw thread in the crank lever, said crank lever being
secured to the spindle passing through the bearing by means of keys or such similar
fastening; a lock nut for securing the bearing part or parts in position substantially
as described and illustrated herein.
3. In ball bearings: grooves or ball races formed upon the ends of a hub at right
angles to the spindle or rotating axis and in which balls are carried, substantially as
described and shewn.
