Improvements in or relating to Ball-bearings.
EZRA BLAKE LAKE, of Ocean City, County of Cape May, State of New Jersey,
United States of America, 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:-
The invention relates to an anti-friction ball-bearing for waggon and bicycle
wheels, and general anti-friction purposes. It consists in the combination in an
anti-friction ball-bearing of a hollow truncated cone ball spacer, having elliptical
or like curved openings therein, which openings are internally tapering or cone-
shaped, and alternately reversed, by which the anti-friction balls carry said spacing
cone evenly between the ball-bearing cones without contacting with said ball-
bearing cones, said anti-friction balls turn in said openings on opposite or axial
points, for reducing the frictional contact with said openings.
On reference to the accompanying sheet of drawings making part of the
Specification;
Figure 1 is a side-view of an anti-friction ball bearing which shows my inven-
tion.
Figure 2 is a side-view of the ball spacer, showing the elliptical or like curved
openings which are internally tapering, or cone-shaped, and alternately reversed.
Figure 3 is a diametrical section of the ball-spacer through opposite openings.
Figure 4 is a sectioned and shortened view of the wheel hub showing the ball-
bearing cone formed in one end of it;
Figure 5 is a sectional view of the outer cone ball-bearing. Figures 3, 4 5
are shown aligned for closing together; and,
Figure 6 is a top or plan view of the ball-spacing cone.
Similar letters refer to similar parts in the several views.
A is the axle and B the hub of bicycle or other vehicle wheel. C is a conical
ball-bearing in the end of the hub B, D) is a conical ball-bearing on the outer
end of the axle A and E a conical anti-friction ball-spacer which is loosely on the
axle A between the conical ball-bearings C, D. Said anti-friction ball-spacer E
is provided with a suitable number of elliptical or like curved anti-friction ball
openings a a¹ a² a³ a¹ a³ aº a² for the reception of the anti-friction balls F which
project inwardly and outwardly and roll between and in contact with the cone
ball-bearing C, D) on axial or opposite points. G is a nut of the axle A for
binding together and adjusting the contact of said cones C, D, E.
The ball-spacing cone E must not contact with the cones C, D and thus produce
friction. The construction by which their proper separation is obtained is clearly
shown in the accompanying drawings, in which the elliptical or other like curved
openings a a¹ a² a²³ a² a² a² a² are tapering or conical and reversed that is the
base of one opening is in alignment with the apex of its adjacent one, and the anti-
friction balls are alternately inserted in said openings from the inside and outside
respectively, by which the bearing of the anti-friction balls and openings is so
adjusted that the openings cannot slide over the balls and cause a frictional contact

page_text: between the ball-spacing cone E and either of the anti-friction ball-bearing
cones C, D. The tapering of the openings cannot conflict with the anti-friction
balls F rolling on opposite or axial points in the elliptical or like curved openings
in the spacing cone, for vastly reducing the friction between said openings and
said anti-friction balls. As shown in Figures 2, 3, 6, said anti-friction balls F
are inserted in the openings a, from the outside of the cone, in a from the inside
in a from the outside, and so on throughout the entire series of ball-openings.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
In an anti-friction ball bearing the combination of a cup and cone ball-
bearing anti-friction balls and a cone-shaped anti-friction ball spaces provided
with elliptical or like curved ball-spacing openings which are tapering and alter-
nately reversed for carrying said ball-spacer evenly between the cup and cone for
the purpose shown and described.
