I, JAMES WILLIAM SMALLMAN, of Camp Hill Grange, near Nuneaton, in the
County of Warwick, Engineer, do hereby declare the nature of this invention
to be as follows:-
-
My invention relates to ball-bearings for bicycles and other vehicles.
The adjustable cup has studs that slide into and project from slots in the end
of the hub; the projecting ends of the studs lying between two locking nuts
screwed on the end of the hub. The studs may be pins screwed tightly into the
cup with heads formed to fit the slots; or they may be solid with the cup; and they
may be concealed by flanges on the nuts or by a flange on one of the nuts.
The bearing adjusted by screwing one nut away from the studs and then
tightening the other nut.
One of the nuts may be split and have a conical part and the other nut may be
adapted to engage with said conical part to contract the split nut and cause the
end of the hub to grip the cup.
The invention may be applied to bottom brackets and to pedals.
The balls may lie between the cups or the cups between the balls. I prefer to
have the balls between the cups for hubs and pedals and the cups between the
balls for bottom brackets.
When the balls are between the cups, the fixed cup may be provided with
studs and be locked by a nut or nuts. Or an ordinary fixed cup screwed up
to a shoulder may be used.
When the cups are between the balls, an oil-retaining cap and a nut (instead of
two nuts) may be employed to bed against the studs and lock the adjustable
cup. The fixed cup may also have studs and be locked by an oil-retaining cap
or by an oil-retaining cap and a nut. Or the fixed cup may be screwed in and
locked by an oil-retaining. cap. The cone near the adjustable cup would be
detachable.

When the balls are between the cups, the fixed cup may be provided with
studs and be locked by a nut or nuts. Or an ordinary fixed cup screwed up
to a shoulder may be used.
When the cups are between the balls, an oil-retaining cap and a nut (instead of
two nuts) may be employed to bed against the studs and lock the adjustable
cup. The fixed cup may also have studs and be locked by an oil-retaining cap
or by an oil-retaining cap and a nut. Or the fixed cup may be screwed in and
locked by an oil-retaining cap. The cone near the adjustable cup would be
detachable.
Reference will now be made to the accompanying drawings.
Fig. 1 is a side elevation of a hub fitted with a cup-adjusting ball-bearing
constructed in accordance with my invention.
Fig. 2 is a corresponding end elevation.
Fig. 3 is a view of the hub and bearing partly in longitudinal section and
partly in side elevation.
Fig. 4 is a side elevation of one of the locking nuts.
Fig. 5 is a similar view of the other locking nut.
Fig. 6 is a side elevation of the adjustable cup.
Fig. 7 is a view of one of the locking nuts in section.
Fig. 8 is a similar view of the other locking nut.
Fig. 9 shows the adjustable cup in section.
Fig. 10 is an end elevation of the hub.
Fig. 11 is a view, partly in longitudinal section and partly in side elevation,
illustrating another way of carrying out my invention.
Fig. 12 is a corresponding end elevation.
Fig. 13 represents the locking nut in section.
Fig. 14 is a similar view of the oil-retaining locking cap..
In Fig. 15, the adjustable cup is shown in section.
A is the shell of the bearing having slots a. B and B are cups with the
balls between them. B is the adjustable cup and has studs b. B₁ is the fixed
cup. C and C are locking nuts that are screwed on the end of the shell. These
locking nuts have flanges c for covering the studs b. The flange c* on the nut C
covers the last turns of the screw-thread on the end of the shell. D is a spindle
with shoulders d and d¹. E and E are cones fixed on the spindle against the
shoulders.
The bearing is adjusted: by screwing the nut C away from the studs and then
tightening the nut C¹. The cup B is securely held against the friction of the
balls owing to the engagement of the studs b with the slots a.
A cap may be used instead of the nut C₁

page_text: A is a shell having cups F and F1 placed between the balls. F is the adjust-
able cup with studs of passing through slots a' in the shell. F is the fixed cup
with studs f engaging in slots a* in the shell. G and G¹ are oil-retaining caps.
The cap G and the nut C* lock the adjustable cup. The cap G¹ locks the fixed
cup. His a spindle with shoulders h and h¹. K and K' are the cones. The cone K
is detachable and the cone K¹ fixed.
To adjust the bearing, the cap G is screwed away from the studs f; the nut C*
being afterwards tightened.
Although bottom brackets and pedals are not shown in the drawings, it will
be readily understood how the invention is applied to them.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. Ball-bearings constructed substantially as described.
.
2. In a ball-bearing, the employment of an adjustable cup locked to the shell
substantially as described.
3. In a ball-bearing, the employment of a cup having studs the ends of which
project from slots in the shell and lie between two nuts (or between a nut and a
cap) substantially as described.
4. In a ball-bearing, the combination of a shell having slots, a cup with studs
projecting from the slots, and nuts (or a nut and a cap) screwed on the shell to
bed against the studs, substantially as set forth.
5. For bicycles and other vehicles, ball-bearings constructed substantially as
described with reference to Figs. to 10 of the accompanying drawings.
6. For bicycles and other vehicles, ball-bearings constructed substantially as
described with reference to Figs. 11 to 15 of the accompanying drawings.
