Improvements in Antifriction Bearings.
We, CONRAD BENDER, of Main Street, Builder, and CHARLES GODFRIED
SIEGMUND MUELLER, of Washington Street, Architect, both of Indianopolis,
Indiana, U.S.A., do hereby declare the nature of this invention to be as follows:
In this invention the shaft or axle (say of a bicycle), as usual in ball bearings,
carries the inner bearings for the balls forming part of the ball races. Between
the balls are arranged discs to separate the balls. As the balls revolve in one
direction the discs are driven in the other direction substantially independent of
the other working parts. The edges of the discs are preferably grooved to fit the
balls. The balls and discs are carried in an annular path formed by two rings.
and between the innermost of the two rings and the shaft or axle are carried small
balls to serve as a ball bearing. The discs which separate the balls in the ball
race are kept in their vertical position by means of small balls arranged in circular
grooves in the two hub parts-one fixed and the other adjustable composing the
ball race and bearing laterally against each side of the discs to keep them in
the vertical position.

We, CONRAD BENDER, of Main Street, Builder, and CHARLES GODFRIED
SIEGMUND MUELLER, of Washington Street, Architect, both of Indianopolis,
Indiana, U.S.A., 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 consists in combining with the usual balls of ball bearings
certain discs and rings in such a manner thall all surfaces which take any consider-
able portion of the weight shall have a revolving in the same direction.
In the accompanying drawing Fig. 1 is a sectional view on line 1-1 of Fig. 2

page_text: of a bearing embodying this invention. Fig. 2 a transverse section on line 2-2
of Fig. 1. Fig. 3 a view similar to Fig. 2 but with the balls, discs, and rings
removed to shew the interior surfaces.
A is an axle. B a hub in the form of a casing surrounding the axle. C the
balls which carry the load. D the intermediate discs. E, F, rings between which
the discs, are placed.
The axle A, as is usual in ball bearings, carries the inner bearings for the balls,
forming part of the ball races usually termed "cones." There are two of these cones
at each end, one a being formed integrally with or secured to said shaft and the
other, a¹ being centrally perforated and screw threaded, both for convenience in
adjustment and ease in assembling the parts, the portions of the shaft upon which
said cones are mounted being correspondingly screw threaded.
The hub B is shewn reduced in size centrally for the purpose of reducing some-
what its weight and bulk, and is composed of a central section of tube with hub
like portions secured thereon and extending outwardly therefrom to a sufficient
size to receive the mechanism of the bearing, and thence in a plane parallel with
the centre to the ends. It will be understood that this construction may be varied
as may be desired. The larger or end portions of this hub B contain the outer
halves of the ball races or cones, and these, like those upon the shaft A are two in
number, the inner ones being forced to position in such a manner as to be held
stationary with the surrounding casing and the outer ones 61 being screw threaded
exteriorly, both so they may be conveniently adjusted and that they may be
assembled with the other parts easily. In the construction shewn, the cones 6 have
flanges which extend to the extreme ends of the bearing structure, and these are
internally screw threaded to receive and carry the outer cones b¹. When these
outer cones are all in place, lock nuts a², 62, are driven in after them, whereby they
are securely locked in position.
The balls C are in themselves ordinary balls and rest in the ball races formed by
the cones a, a, b, b¹, and carry the hub B upon the axle A in a known manner,
except that the balls are somewhat larger in diameter than are commonly used in
bearings of corresponding size, while they are fewer in number, as a portion of
the space ordinarily occupied by balls is occupied by the discs D.
'The discs D are arranged between the balls C and serve to prevent them from
rubbing against each other as the parts revolve. Obviously as the balls revolve in
one direction the discs, which are driven thereby, are driven in the other direction.
The discs may better serve their purpose and remain more easily in place if their
peripheries are somewhat grooved or concaved as shewn in the drawing.
The rings E, F, form tracks for the discs D one interior and the other exterior
thereof, and they serve to hold said discs in place. Said discs are intended to
run as free from contact with other parts as is possible and in no case carry
much weight or are subjected to much strain. Nevertheless, to insure that they
shall maintain exactly the desired position, small balls e are interposed between
the inner ring E and the axle, and this latter is grooved slightly at the point where
the balls rest for the purpose of retaining them in place. The balls e receive what-
ever strain may come upon the rings, and thus not only is the structure as a whole,
consisting of the discs D and rings E, F, maintained in place, but friction is reduced
to a minimum.
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:
-
F1: The combination, in a ball bearing, of the axle, a surrounding hub, suit-
able ball races composed of cones secured to said axle and to said hub, balls in said
ball races, discs between the respective balls, and rings forming tracks for said
discs, substantially as described and shewn.
2. The combination, in a ball bearing, of the axle, the hub, ball races formed
on said axle and said hub, balls in said ball races, discs interposed between the

page_text: balls, rings forming tracks for said discs, and balls interposed between the inner
ring and the axle, substantially as described and shewn.
