Improvements in Ball and Roller Bearings.
We, JONATHAN WATERBURY, of Number 221, Ralph Avenue, Borough of
Brooklyn, in the City of New York, Kings County and State of New York, U.S.A.,
Engineer, and HERMAN GEIGER, of Number 104, South Street, City of New York,
in the County and State of New York, U.S.A.. Fish Dealer, do hereby declare
the nature of this invention to be as follows:-
A ball cup is used consisting of an annular band, and a flange which projects
inwardly at right angles to said band; a cone is mounted upon the axle in an
adjustable manner in the open end of said cup, and forms a ball race in which
the balls will have two tangential points of contact; viz., with the cone, and
with the flange, and will have a third point of contact, substantially tangential,
with the annular band. A plate is mounted in the cup against the said flange,
and is provided with radial arms, on the side of which opposite to said flange,
are mounted one, or more, rollers, which are less in diameter than the said
balls, and by which the balls are separated.

Improvements in Ball and Roller Bearings.

We, JONATHAN WATERBURY, of Number 221, Ralph Avenue, Borough of
Brooklyn, in the City of New York, Kings County and State of New York, U.S.A.,
Engineer, and HERMAN GEIGER, of Number 104, South Street, City of New York,
in the County and State of New York, U.S.A., Fish Dealer, 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 and roller bearings; and the object thereof is
to provide a bearing of this kind in which the bearing-balls are separated by
rollers which do not come in contact with the ball race but simply serve to
separate the bearing-balls so that all the rotating bodies have adjacent sides
rotating in the same direction at the point of contact with each other thereby
avoiding friction.
In the accompanying drawing:
Figure 1 is a view of a portion of a shaft with a sectional view of one form of
my invention applied thereto;
Figure 2 is a plan view of the bearing-balls and separating rollers; and,

page_text: Figure 3 shows a modified form of construction.
In the practice of our invention we provide a plate 5, which we mount loosely
in the cup 6, which is mounted in the hub, or bracket of a bicycle, or in any
journal box, in a manner well known and therefore not described, in this con-
nection. The shaft is, indicated by 7, and the plate 5 is provided with a central
aperture 8, which is greater in diameter than the shaft 7, and with radial arms 9,
to each of which is secured a short shaft 10, having a head 11, and on each
shaft 10, we mount a small roller 12. The plate 5 is so proportioned in size that
when placed in the cup 6 the peripheries of the rollers 12 will not come in con-
tact with the inner wall of the cup; however, the aperture 8 may be of such
a size as to permit one, or more of the rollers to touch the wall of the cup.
Between each of the radial arms 9, we mount a bearing-ball 13, which balls
are so proportioned in size that they will fit loosely between the rollers 12, and
the diameter of the balls is greater than the diameter of the rollers.
On the shaft 7 we mount a cone 14, which bears against, the balls, as shown
at 15, whereby the shaft 7 is supported by the balls 13 and no part of it comes
in contact with any part of the cup 6. The cup. 6 is the ordinary cup used in
bicycle construction, and consists of an annular band and an inwardly-directed
flange, and the cone 14 fits in the open end of said cup, so that the bearing-balls
have but three points of contact in the raceway-viz., against the inner wall of
the annular band of the cup, against the inwardly-directed flange, and against
the cone. It will thus be seen that we have adapted our device to the most im-
proved method of forming a raceway without sacrificing any of the. essential
features thereof.
..
The plain side of the plate 5 rotates in contact with the inwardly-directed
flange of the cup; but as the rollers 12, which are mounted on stub-shafts. on
the opposite side of said plate, are less in diameter than the bearing-balls the
plate is practically carried by the bearing-balls and the friction between the
plate 5 and flange of the cup will be inappreciable...
In antifriction-bearings where balls are used exclusively the balls all rotate
in one direction, so that the sides adjacent to each other rotate in opposite direc-
tions thereby causing friction. As the rollers 12 in this construction do not
come in contact with the cone 14 nor with the cup 6, they are rotated by the
balls alone, and, therefore, always with, the balls, so that there is no friction
between the balls and rollers which would be in any wise appreciable. Another
advantage is that the balls are always kept at equidistant points, so the cone is
supported and held at every point, while with balls alone it is impossible to
place them so close together in the cup but that there will be a slight space left
between them at the upper side of the cup when in use, thereby causing a slight
play of the axle.
In Figure 3 we have shown a slight modification in which the radial arms 91
are reduced in number and made larger, and two.rollers 121 are mounted upon
each arm.
A possible advantage of this construction lies in the 'fact that fewer
bearing-balls 13 are required and the adjacent balls do not come in contact, with
the same roller, so that if for any reason the balls did not rotate in unison there
would be no friction between the balls and the rollers.
While we have particularly described our invention as being applicable to
antifriction-bearings in connection with shafts, we do not wish to confine our-
selves to that use, as the bearing is applicable to other uses, such as sheaves,
and we claim the right to make any changes or alterations which fairly come
within the scope of our invention.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what
we claim is: -
