Improvements in Ball Bearings.
I, JULIUS PREUSSGER of No. 1º Berg Street, Zittau, Kingdom of Saxony,
Germany, Mechanic, do hereby declare the nature of this invention to be as
follows:-
The present invention relates to a ball-bearing axle for cycles which entirely
does away with the breaking or bursting of the cones which bear the balls, at the
same time enabling the cones to be made very small.
The cones, which used to be screwed on to the axle are now welded on, and then
hardened, so as to form one part with the core. This permits of making the walls
of the cones very thin, and although the ball bearing surfaces are very small, great
strength is obtained because the tenaceous core, which is made of soft iron, is
always borne upon in common with the cones. In order to adjust a bearing
carrying such axle, either a piece is inserted between the nuts, which close up the
balls, and the nave, so that the piece can be screwed into the nave, or the axle is
divided and its ends are screwed into a screw socket. By turning the axle, the
bearing can thus be easily adjusted.
Dated this 30th day of May 1893.

Improvements in Ball Bearings.
1, JULIUS PREUSSGER of 1B Berg Strasse, Zittau, Kingdom of Saxony, Germany,
Mechanic do hereby declare the nature. of this invention and in what manner the
saine is to be performed, to be particularly described and ascertained in and by
the following statement :-
The present invention relates to ball-bearing axle for cycles which entirely does
away with the cracking of the cones which bear the balls, at the same time enabling
the cones to be made very small.
Fig. 1 of the accompanying drawing shows this axle in connection with a ball-
bearing, and
Fig. 2 shows how the axle can be adjusted.
The cones b, which used to be screwed on the axle f, are now welded on or
soldered on, and then hardened, so as to form one piece with the core f. This
permits of making the walls of the cones very thin, and although the ball bearing
surfaces are very small, great strength is obtained because the tenaceous core
which is made of soft iron, is always borne upon in common with the cones b.
order to adjust a bearing carrying such axle, either a piece d is inserted between
the nuts c, which close up the balls, and the nave e, so that the piece d can be
screwed into the nave, or-as shown by Fig. 2-the axle is divided and its ends
are screwed into a screw socket g. By turning the axle, the bearing can thus be
easily adjusted.
Having now particularly described and ascertamed the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. A ball-bearing axle for cycles with which the bearing cones are metalically

page_text: connected by being welded or soldered on, instead of being screwed on as heretofore
substantially as set forth.
2. The adjusting of a ball-bearing provided with the above axle, either through
dividing the latter and joining it by means of a screw-coupling, or through the
insertion of part d into the nave substantially as set forth.
Dated this 24th day of February 1894.
