Improvements in Ball Bearings for Axles.
We, WILLIAM JOSEPH BUSSE, of No. 84 Market Street, Machinist, and
GEORGE FREDRICK LOCHNER, of No. 112 West Maddison Street, Merchant,
both of Chicago, in the County of Cook, and State of Illinois, 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:-
This invention relates to that type of axle bearings in which a series of balls
are interposed between the axle and hub to form a rolling anti-friction bearing
between the two.
And the object of the present invention is to provide a simple and efficient
construction of such bearings, in which a sliding of one ball upon another, as well
as upon the bearing surfaces, is entirely prevented and at the same time a
substantial bearing of the different balls is provided that will resist in a very
perfect manner the end thrust of the axle, in use.
We attain such object by the construction and arrangement of parts illustrated
in the accompanying drawings, in which:
Figure 1, is an enlarged elevation of a bicycle axle and hub, with parts in
sections, and with other portions broken away, illustrating the present invention.
Figure 2, a side elevation of the inner bearing collar of the bearing in a modified
form from that shown in Figure 1.
Similar letters of reference indicate like parts in both views.
Referring to the drawings, 1 represents the axle, and 2 the hub or shell provided
at each end with the usual enlarged cavities, in which are arranged the annular
lining or bearing sleeve 3 of steel or like hardened metal, and which constitute
an internal circular track for the movement of the bearing balls.
4, is a bearing collar of the axle, having a central bore to fit that axle, which
axle is formed with a stop shoulder 5, against which such collar abuts when in
position.
6 is a nut screwing upon the axle, and adapted to hold the bearing collars 4 in
proper position.
The bearing collar is formed with a circumferential groove 7, and with a circular
outer rim 8, that constitute circular tracks for the balls of the bearing, the rim 8
being of a diameter about equal to the internal diameter of the lining sleeve 3, so
as to constitute a closure for the outer end of the hub cavity.
The bearing collar 4 may be made of a single piece of metal as shown in Figure 1,
or in sections as shown in Figure 2, without departing from the spirit of the
present invention.
9 are the main bearing balls, a series of which are arranged in the circumferential
groove 7 and between the same and the inner surface of the bearing sleeve 8, as
shown.
10 and 11 are counterpart series of intermediate or auxiliary balls, smaller in
size than the main balls 9, and arranged at each side and between the series
of main balls 9, as shown, so as to hold such main balls 9 in separated relation.
Such series of intermediate balls 10 and 11, have bearing against the main
balls 9, the inner surface of the bearing sleeve 3, and vertical wall 12 of the bub,
and the outer rim 8 of the bearing collar 7, respectively.
13, is a cap adapted to fit upon the ends of the hub or shell 2, the head 14 of

page_text: which is formed with a central orifice for the movement of the nut 6, such head 14,
fitting against the outer surface of. the bearing, collar 4, a constitute a dust proof
joint between such collar and the hub, to prevent entrance of dust, etc. to the ball
bearing proper....
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
A ball bearing for axles, comprising in combination a hub 1, having an enlarged
bearing.cavity for, the balls, an.axle, a bearing collar as 4; a series of main.balls 9,
and; two series of auxiliary balls 10 and 11, arranged. at the. sides. and between
the. main series of balls 9, and having bearing against the inain balls, and.
the, concentric inuer surface and the end surfaces of the ball hearing, cavity,
substantially as set forth.
Dated this 29th day of September 1896.
