PROVISIONAL SPECIFICATION.
Improvements in Locking Devices for Anti-friction Ball-bearing
Races, Cups, Discs, or the like.
I, ISAAC WHITEHOUSE, of 56, Hampton Road, Birchfield, Birmingham, in the
County of Warwick, Machinist, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in devices for locking the anti-friction
ball-bearing races, cups discs or other like parts, such for example as those em-
ployed in what is known as a disc adjusting wheel hub, or a bottom bracket bear-
ing of a bicycle or like vehicle.
According to this invention a ball race cup, disc, or other like part is formed
with an external screw thread and is screwed into, and is adjustable in the main
part in the usual manner.
It is also formed with a reduced outer part or extension, the inner end of which
is formed preferably conical, and the outer end with a screw thread.
Fitting on the conical part of the extension is a washer provided with an open-
ing corresponding to that of the said conical part, whilst on the screwed portion
is a nut, by means of which the washer is forced on to and locked on the conical
part.
The washer fits within the main part, and its periphery is formed with one or
more extensions, which take into recesses in the said main part, so that it cannot
possibly rotate.
It therefore follows that when the cup or disc is locked to the washer in the
manner described, the former cannot be rotated until released from-said washer,
but when released, the cup or disc may be moved any distance relatively to the
main part without readjustment of the locking device, as the latter moves bodily
with the cup or disc.
The screw on the extension of the cup or disc may be cut the same or the reverse
hand to that on the main part as preferred.
When it is desired to permanently lock one of the cups or discs of a ball bear-
ing to the main part into which it is screwed, the said cup is preferably formed
with a flange the diameter of which is equal to the diameter of a preferably
reduced part at the end of the main part.
Fitting over the flange and the reduced end of the main part, is a ring provided
with a key or internal projection which engages with a key way or recess cut
in both the flange of the cup or disc, and the end of the main part.
This ring may be held in position by a ring or nut which is screwed on to an
extension of the cup or disc.

Races, Cups, Discs, or the like.
I, ISAAC WHITEHOUSE, of 56, Hampton Road, Birchfield, Birmingham, in the
County of Warwick, Machinist, 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 improvements in devices for locking anti-friction
ball bearing races, cups, discs or the like, such for example as the bearing cups
or discs of what is known as a disc adjusting wheel hub, or a bottom bracket bear-
ing of a bicycle, or like bearing.
The invention will be best understood by reference to the accompanying draw-
ings, in which
Fig. 1 is a longitudinal section showing my invention applied to a wheel hub.
Fig. 2 is a side view, and
Fig. 3 an end view showing one of the ball race cups or discs.
Fig. 4 is a side view, and
Fig. 5 a face view showing the corresponding locking washer.
Fig. 6 is a side view, and
Fig. 7 an end view showing the other ball race cup or disc.
Fig. 8 is a side view, and
Fig. 9 an end view of the corresponding locking ring.
Like letters indicate like parts throughout the drawings.
!
According to this invention both the adjustable and fixed ball race cups or
discs A and B respectively, are formed with an external screw thread, and are
screwed into the main part C, (which as shown in the present case is a wheel hub)
in the usual well known manner.
The adjustable ball race cup or disc A which is shown detached in Figs. 21
and 3, is formed with a concentric cylindrical extension A¹ of reduced diameter,
the outer end of which is formed with a screw thread, and the inner end with a
plain conical part A³.
Fitting on the conical part A3 of the cup or disc A, is a washer D, which is
shown detached in Figs. 4 and 5, whilst on the screwed part A¹ is a nut E by
means of which the washer D, is forced on to and thus locked on the conical
part A on which it is placed.
The washer D fits loosely within the end of the main part or hub C, but on its
periphery are one or more projections D¹ which engages in longitudinal recesses
or keyways formed within the main part C and thus prevent one from possibly 3
rotating relatively to the other.
It therefore follows that when the cup or disc A is locked to the washer D, by
means of the conical part A2 and nut E on the reduced extension of the said cup
or disc, it cannot be rotated within the main part C until released from the
washer D, but when released the cup or disc A may be moved any distance rela- 4
tively to the main part C without re-adjusting the locking device described, as
the latter moves bodily with the cup or disc.
The screw thread on the reduced extension A¹ of the cup or disc A. may be cut
the same or reverse hand to that on the body of the cup or disc as preferred.
The extension A¹ of the cup or disc A may also be formed with flat parts as 4
shown so that a spanner may be placed thereon to adjust the said cup.
The fixed bearing cup or disc B which is shown detached in Figs. 6 and 7 is

page_text: formed with a flange B³ which is equal in diameter to the end C³ of the main
part or hub C.
Fitting over the flange B and the end C2 of the hub, is a ring G which is
shown detached in Figs. 8 and 9. This ring G is provided with a key or internal
projection G which engages in a recess B³ in both the flange B2 and end C2 of
the hub, and thus prevents the rotation of one relatively to the other.
The ring G may be held in position by a nut H which is screwed on to an
extension B of the cup or disc B as shown.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is;-
--
1. In a locking device for anti-friction ball bearing races, cups, discs or the like
the combination with an adjustable cup or disc such as A provided with a screwed
extension A' and a conical part such as A2 of a washer such as I fitting on the
conical part A2 and engaging with the main part or hub C and a nut E on the
screwed part A¹ for locking the washer on the conical part A² substantially as
described.
2. In a locking device for anti-friction ball bearing races, cups, discs or the like
the combination with an adjustable cup or disc such as A provided with a screwed
extension A and a conical part such as A2 of a washer such as 1 fitting on the
conical part A2 provided with one or more projections such as D₁ which engages
in recesses C in the main part C and a nut E on the screwed part A¹ substantially
as and for the purpose described.
3. In a locking device for anti-friction ball bearing races, cups, discs or the like
the combination with a fixed cup or disc such as B provided with a flange 132 of
a ring such as G fitting over the flange 12 and end 2 of the main part provided
with a key or internal projection G¹ which engages in a corresponding recess in
both the flange B2 and main part and a nut H for holding the ring G in
position substantially as described.
4. The combination and arrangement of parts constituting the complete locking
device for the adjustable anti-friction ball bearing race, cup, disc or the like sub-
stantially as described and illustrated in the accompanying drawings.
5. The combination and arrangement of parts constituting the complete lock-
ing device for the fixed anti-friction ball bearing race, cup disc or the like sub-
stantially as described and illustrated in the accompanying drawings.
Dated this 4th day of October 1898.
