PROVISIONAL SPECIFICATION.
Improvements in and relating to Bearings for Cycles and other
Light Vehicles.
We FREDERICK SAMUEL BUCKINGHAM Manager of Works, and WILLIAM
NEWTON, Cycle Manufacturer, both of the Elswick Cycle Works, Newcastle-on-
Tyne, in the County of Northumberland do hereby declare the nature of this
invention to be as follows:-
:-
Our invention relates to an improved construction of ball bearing for the wheels
and other parts of cycles and other light vehicles, and it consists in mounting the
adjustable cone or cones in the case of the bearing, or its equivalent, thus enabling
the cones or their equivalents on the axle to be formed or rigidly fixed thereon, the
object being to obtain an efficient bearing, simple of construction, easily adjustable,
and not liable to get out of order.
We attain this end by forming in suitable positions near each end of the axle
circumferential grooves the inner shoulders of which are made higher than the
outer ones-the axle being thickened at these places for the purpose, thus forming
a kind of combination cone and groove. Instead of forming these combination
cones and grooves direct on the axle they may be formed on collars adapted to be
fixed to the axle.
In the ends of the bearing cases, or their equivalents-such as the hub of a
wheel-are screwed cones adapted to form with the combined cones and grooves on
the axle, complete races for two rows of balls. These cones are made of such a
length that they stand proud of the ends of the cases, or their equivalents when
the bearing is adjusted, and they are locked to the said cases or their equivalents
by locknuts threaded on them and bearing against the ends of the cases or their
equivalents.

COMPLETE SPECIFICATION.
Improvements in and relating to Bearings for Cycles and other
Light Vehioles.
We FREDERICK SAMUEL BUCKINGHAM Manager of Works, and WILLIAM
NEWTON, Cycle Manufacturer, both of the Elswick Cycle Works Newcastle-on-
Tyne, in the County of Northumberland, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
Our invention relates to an improved construction of ball bearing for the wheels
and other parts of cycles and other light vehicles, and it consists in mounting the
adjustable cone or cones in the case of the bearing, or its equivalent, thus enabling
the cones or their equivalents on the axle to be formed or rigidly fixed thereon; the
object being to obtain an efficient bearing simple of construction, easily adjustable,
and not liable to get out of order.
We attain this end in the manner illustrated by the accompanying drawing, in
which
Figure 1 is a view in longitudinal section of the hub of a wheel fitted with our
improved ball bearings.

page_text: Figures 2 and 3 are views in side elevation of one of the adjustable cones and lock
nuts respectively.
Figure 4 is a broken view of a modification of our invention.
Figure 5 is a view in transverse section thereof through the ball race, and
Figure 6 is an end view thereof.
Throughout the views similar parts are marked with like letters of reference.
On each end of the axle A adapted to carry the wheel we form enlargements a
in which are formed annular grooves a', a', forming the races for the balls z, z, etc.
The inner shoulders of these annular grooves are formed higher than the outer ones
so that each groove forms a kind of combination cone and groove. Instead of forming
the enlargements a, a, on the axle they may take the form of collars adapted to be
fixed to the said axle.
The hub B of the wheel has extensions B', B', formed on its ends-outside its
flanges to form the cases for the bearings. The interior of these extensions are
threaded to receive screwed cones C, C, which are preferably made of a slightly curved
shape as shown by Figures 1 and 4 of the accompanying drawing. These cones
after the bearings are adjusted are locked to the extensions B', B', of the hub B by
lock nuts C, C, adapted to screw outo the cones C, C, and bed against the ends of
the extensions of the hub. These lock nuts C', C', preferably take the form of
rings and they and also the cones C, C, are provided with small facial holes c, c,
to enable them to be manipulated by a stud pin spanner. As a modification one
only of the cones C, C, may be made adjustable, the other one being screwed dead
up against a shoulder in the extension of the hub of the wheel and locked thereto
by a small set screw. As a further means of locking the cones C, C, to the exten-
sions B, B', of the hub B, we thread one or more small set screws b, into the said
extensións B', B', to engage with a series of notches or grooves c¹ c' etc., cut or
formed in the cones C, C, as shown by Figures 4, 5 and 6. These set screws afford
a means of locking the cones while the lock nuts are being tightened up, and they
act as a lock in case the said lock nuts work loose.
When the hub is intended for a driving wheel, a chain wheel is mounted on one
of the extensions B of the hub as shown by dotted lines in Figure 1.
It will be seen that by this construction, the bearings are made as nearly dust proof
ns is possible, that they will contain a certain amount of oil within them, that they
can with equal facility be adjusted from either side, that they do not interfere with
the adjustment of the tension of the driving chain, and that their adjustment
is not liable to be accidentally varied when removing the axle from the frame of a
machine.
We wish it to be particularly understood that we do not limit ourselves to the
precise details of construction herein before described and illustrated by the accom-
panying drawing, but that we hold ourselves at liberty to make such changes and
alterations as fairly fall within the spirit and scope of our invention.
We are aware that it is not broadly new to use adjustable cones in combination
with annular grooves and balls or spheres and we do not therefore broadly claim
such as our invention, but what we do claim and desire to secure by Letters
Patent is :-
1. The improved construction of ball bearing hub for the wheels of cycles and
other light vehicles constructed, arranged, and operating specifically as set forth.
2. The combination with the hub of a wheel for velocipedes and similar vehicles,
of extensions on the ends of the said hub forming cases for the bearings, of adjust-
able cones screwing into the said extensions so as to be capable of adjustment
therewith, of lock nuts screwing on to the said cones and adapted to lock them to
the said extensions of the hub, of enlargements formed on or attached to the axle
at or near each end thereof, of annular grooves formed in the said enlargements,
and of balls or spheres interposed between the adjustable cones and the annular
grooves, as set forth.
3. In a wheel for velocipedes and similar vehicles the combination with the hub

page_text: and axle thereof, of adjustable cones screwed into extensions of the hub and locked
thereto by suitable lock nuts, of enlargements formed on or fixed to the axle, of
annular grooves formed in the said enlargements each having its inner shoulder
higher than the outer one forming a kind of combined cone and groove at or near
each end of the axle, and of balls or spheres placed in the races formed by and
between the said adjustable cones in the extensions of the hub and the annular
grooves in the enlargements on the axle, as set forth.
4. The combination with the hub of a wheel for velocipedes and similar vehicles,
of extensions on the ends of the said hub forming cases for the bearings, of adjust-
able cones screwing into the said extensions so as to be capable of adjustment there-
with, of lock nuts screwing on to the said cones and adapted to lock them to the
said extensions of the hub, of set screws threaded into the extensions of the hub and
adapted to engage with notches or grooves in the adjustable cones, of enlargements
formed on or attached to the axle at or near each end thereof, of annular grooves
formed in the said enlargements, and of balls or spheres interposed between the
adjustable cones and the annular grooves, as set forth.
5. In a wheel for velocipedes and similar vehicles the combination with the hub
and axle thereof, of adjustable cones screwed into extensions of the hub and locked
thereto by suitable lock nuts and set screws, of enlargements formed on or fixed to
the axle, of annular grooves formed in the said enlargements each having its inner
shoulder higher than the outer one forming a kind of combined cone and groove at
or near each end of the axle, and of balls or spheres placed in the races formed by
and between the said adjustable cones in the extensions of the hub and the annular
grooves in the enlargements on the axle, as set forth.
