Improvements in Ball Bearings.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 ball-bearings, such as those employed for the wheels
and cranks of bicycles, and it has for its object to reduce the number of
balls employed in such bearings, and prevent rubbing contact between the balls.
The invention consists in the improvements which I will now proceed to describe
and claim.
Of the accompanying drawings, forming a part of this specification,-
Figure 1 represents a longitudinal section of a bicycle-wheel hub, and an
elevation of the axle on which it is mounted.
Figure 2 represents an end elevation of the same.
Figure 3 represents a perspective view of the separating device, detached.
The same letters of reference indicate the same parts in all the figures.
In the drawings-
a a represent the balls, which are interposed between the cones b b on the axle f
and the cups on the hub d. The said cones and sockets are or may be of
the usual general form and relative arrangement, the balls being interposed
between them, as shown.
In carrying out my invention, I provide spacing-plates g, which are formed
and arranged to project outwardly from the bases of the cones into the ball-
receiving spaces between the cones and the cups, the said plates having recesses g¹
formed to receive the balls, and intermediate projections 9 which project between
the balls and keep the balls of each series separated from each other, as indicated
in Figure 2.
The said projections are preferably formed as fanges projecting from one
side of the plate g, extending partly across the ball-containing space. The
separating-plates are revolubly mounted, so that their ball-engaging projections
are kept in their operative position with relation to the balls, without liability
of displacement, and are at the same time free to revolve with the balls,
about the axle f. The plates gare here shown as provided with flanges g
surrounding the axle and adapted to rotate thereon, the said flanges projecting
between the axle and the cups b. The inner ends of the cones form shoulders,
which prevent the plates g from moving laterally in one direction, the inner
portions of the cups preventing lateral movement of the plates in the opposite
direction.
I do not limit myself to the means here shown for revolubly mounting the
separating-plates, and may mount said plates in any other suitable way.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondents, I declare that what I claim is :-

a separator-plate revolubly mounted between the cup and cone and notched to
receive said balls.
