Improvements in and connected with Ball Bearings for Cycles
and other Vehicles.
We, WILLIAM HENDRY MILLIGAN, of 47, Walkenshaw Street, Bridgeton,
Glasgow, Mechanic, and ANDREW HENDERSON, of 24, Dalmarnock Road, Bridge-
ton, Glasgow, Mechanic; do hereby declare the nature of this invention to be
as follows:-
This invention relates to the ball bearings for cycles and other vehicles. The
invention is specially applicable to the ball bearings. of the hubs.and the bottom
bracket of bicycles.
The object of the invention is to improve the construction of such ball bearings
and the parts connected therewith.
In carrying out our invention for, say, the hub of the rear.oradriving..wheel
of a bicycle we fit loosely upon the spindle two double cone sleeves one at each
end and these sleeves are made with recesses or teeth or equivalent whereby they
may be clutched to clutch pieces screwed on the ends of the spindle. Besides
the usual cup made at each side of the hub there is a second adjustable cup
screwed into each side of the hub and which can be locked in place by..means of
a lock or jam nut.
The double cone sleeve together with the double cups at each side of the hub
constitute double ball races (instead of single ball races as at present). round
which two sets of balls run at each side of the hub.
Each double icone sleeve preferably takes the form of a tubular piece having a
circumferential ridge at or near the centre. which is carefully. turned on both
sides so as to form a double cone. The end of the tubular piece is made with
two projections or teeth for clutching the clutch piece as aforesaid.
Each clutch piece may take the form of a nut with recesses on one side which
catch the projections on the double cone sleeve.
With this construction of the ball bearing and the parts connected therewith
by simply screwing off the clutch piece at one end of the spindle the latter can
be taken out of place without disturbing the position of the balls in any way.
The bearings can be very easily and delicately adjusted and there is not the
same liability of the balls being pinched as at present where single sets of balls
are used.

We, WILLIAM HENDY MILLIGAN, of 47, Walkenshaw Street, Bridgeton,
Glasgow, Mechanic, and ANDREW HENDERSON, of 24, Dalmarnock Road, Bridge-
ton, Glasgow, Mechanic, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to the ball bearings for cycles and other vehicles. The
invention is specially applicable to the ball bearings of the hubs and the bottom
bracket of bicycles.
The object of the invention is to improve the construction of such ball bearings
and the parts connected therewith.
In order that our said invention may be properly understood we have hereunto
appended an explanatory sheet of drawings, whereon,
Fig. 1 is a section taken through the hub of the steering wheel of a bicycle
and showing a double set of balls at each side.
Fig. 2 is a similar section with a single set of balls at each side.
Fig. 3 is another section.
Fig. 4 is a section showing the axle with its sleeves.
Figs. 5, 6 and 7 are details.
The hub of the steering wheel of a bicycle is merely shown on the drawings
by way of example.
In carrying out our invention for, say, the hub of the steering wheel of a
bicycle we fit loosely upon the spindle or axle a two double cone sleeves b, b¹,
one at each end and these sleeves are made with teeth or equivalent c whereby
they, may be clutched to corresponding recessed clutch pieces d, di, screwed on
the ends of the spindle. Besides the usual cup e fitted at each side of the hub
there is a second adjustable cup f screwed into each side of the hub and which
can be locked in place by means of a lock or jam nut g. h are balls. i is the
hub. the fork and k nuts.
The double cone sleeve together with the double cups at each side of the hub
constitute double ball races (instead of single ball races as at present) round
which two sets of balls run at cach side of the hub.
The
In Fig. 2 there is only a single set of balls h running against the cups f and
in Fig. 3 there is but a single set of balls h running against the cups e.
single set of balls may be used when so desired, and when one bearing is worn
the balls may be changed to the other bearing. In cases where there are two
sets of balls one set can be withdrawn when so desired.
Each double cone sleeve 6 (or b¹) preferably takes the form of a tubular piece
(Fig. 5) having a circumferential ridge c which is carefully turned on both sides
so as to form a double cone. The end of the tubular piece is made with two
projections or teeth c for clutching the clutch piece as aforesaid.
Each clutch piece (d or d¹) may take the form of a nut (see Fig. 6) with
recesses on one side which catch the projections c on the double cone sleeve.
With this construction of the ball bearing and the parts connected therewith,
by simply screwing off the clutch piece at one end of the spindle the latter can
be taken out of place without disturbing the position of the sleeves and the balls
in any way. The bearings can be very easily and delicately adjusted and there
is not the same liability of the balls being pinched as at present where single
sets of balls are used.

page_text: Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we consider novel and desire to claim is:-
1. Ball bearings and the parts connected therewith made substantially as
herein before described and shown on the drawings annexed.
2. In a ball bearing the combination of a spindle (or axle), coned sleeves
fitted loosely upon the spindle, and clutches for clutching the sleeves to the
spindle, substantially as hereinbefore described with reference to the drawings
annexed.
