Improvements in Ball. Bearings.
1, PRESTON DAVIES, of Spencer House, West Hill Road, Southfields, in the
County of Surrey, Tyre Manufacturer, do hereby declare the nature of this
invention to be as follows:-
My present invention has reference to bearings of the character patented to me
by Letters Patent No. 17,407 dated September 29th 1892.
In the Specification of that Patent there is described a bearing having inter-
mediate rows of balls constructed so as to permit of both radial and lateral
adjustment by one mechanical action, the. load being equally distributed over
the axle.
In certain bearings there is greater wear at some points of the bearing than at
others. For instance in the case of a chain driven. bicycle it is found that the
side nearest the driving chain is the part of greatest wear of the bearing, both of
the bottom bracket and of the driving wheel.
My present invention is more especially: applicable to bearings wherein this
uneven character of strain is present but is not necessarily limitedithereto.
In constructing a bearing in accordance with my invention I place towards 'one
end of the axle-in the case of a chain driven bicycle the end nearest the chain
wheel-an end cone fixed thereon. The axle.towards its opposite end is screwed
to receive a similar cone adjustable thereon.. The bearing is contained within a
suitable casing which extends between the respective end.cones and is provided
interiorly with two ball cups which instead of being at each end of the bearing as
now generally made one cup is at the end.and the other-the one nearer the
driving chain is more towards the centre of the bearing to allow. of the
introduction of other cups and cones such as hereinafter described:.. A collar
having its two faces suitably bevelled fits loosely over the axle and is located
between the fixed end cone and a double cone which is on the axle. This collar is
intended to be free of the axle and fixed to the casing in such a manner that while
it cannot move separately in a radial direction it is free to slide laterally for which
purpose it may have a lateral slot on its periphery into which atpin or key from
the casing passes.. The double cone herein before mentioned. also has its faces
suitably bevelled and is similarly fixed to the axle.. That is.to say while it is free to
move laterally it is prevented from moving radially except in conjunction with the
axle. This may be effected by slotting the axle into which slot a pintor. key
attached to the cone engages. Rows of balls are placed at each end of the bearing
and at each side of the. double cone.
By operating the adjustable end cone the whole-bearing is adjusted and fall balls
thrust equally on to their paths.
Although above described as having four rows of balls, three at one end and one
at the other, I do not limit myself to the use of that number. in the construction.of
my bearing: The number of rows of balls as well as the disposition of the conce
and collars may be varied without departing. from my tinvention:

1, PRESTON DAVIES, of Spencer House, West Hill Road, Southfields, in the
County of Surrey, Tyre Manufacturer, 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:-
My present invention. has reference to bearings of the character patented to me
by Letters Patent No. 17,407 dated September 29th 1892.
In the Specification of that Patent there is described a bearing having inter-
mediate rows of balls constructed so as to permit of both radial and lateral
adjustment by one mechanical action, the load being equally distributed over
the axle.
In certain bearings there is greater wear at some points of the bearing than at
others. For instance in the case of a chain-driven bicycle it is found that the side
nearest the driving chain is the part of greatest wear of the bearing both of the
bottom bracket and of the driving wheel.
My present invention is more especially applicable to bearings wherein this
uneven character of strain is present but is not necessarily limited thereto.
The accompanying drawings, which are sectional elevations, illustrate my
invention, Figure 1 showing its application to the hub of a bicycle driving wheel
and Figure 2 to that of a bottom bracket.
In constructing a bearing in accordance with my invention I place towards oue
end of the axle in the case of a chain-driven bicycle the end nearest the chain
wheel A-an end cone B which when once adjusted in position is intended to be
kept stationary and not used for the ordinary adjustment of the bearing, and at
the opposite end of the bearing is an adjustable end cone B. The whole bearing
is contained within a suitable casing D which is provided interiorly with, or
contains, two ball cups or paths E and E¹ which instead of being at each end of
the bearing as now generally made one cup or path E' is at or near one end while
the other one E is more towards the centre of the bearing to allow of the
introduction of other cups and cones sugh as hereinafter described. Figure 1 shows
the cups E and E' free of the axle and designed to revolve with the casing which
is formed or provided with internal flanges or annular collars d, d' as abutments
for such cups.
A collar F fits loosely over the axle while a double cone G is
secured to the axle. These parts F and G are capable of sliding laterally along
the parts to which they are secured but they are prevented from independent radial
movement. . For this purpose .the parts may engage, with a feather or key f while
the parts G may each have a ping passing through them and engaging with a
slot g formed on the axle. The parts B, E and F have faces bevelled suitably.or
similarly to the cones described in my said prior Specification. Rows of balls H
are placed at each end of the bearing and at each side of the movable cones.
Figure 2. shows the axle itself formed with ball paths E, E¹ (in that case the
flanges d, d may be dispensed with) and the end cones B, B' screwed into the
casing and held in position by set-screws K, K' which in the case of K may engage
with an aperture k in the end cone B and in the case of K' may pass into the
cusing D and bear on a plug k¹ of soft metal which in its turn bears on the thread
of B'. The set-screws are secured in position by the lock nuts k³.
It will be seen that by operating the end cone B₁ the whole bearing is adjusted
and all balls thrust equally on to their paths.
Although above described as having four rows of balls three at one end and one
at the other, I do not limit myself to the use of that number in the construction of
my bearing. The number of rows of balls as well as the disposition of the cones
and collars may be varied without departing from my invention. Nor is the

page_text: application of my invention limited to velocipede wheels, it being obvious that it
may be applied with equal or greater advantage to the bearings of other vehicle
wheels and rotatory bodies.
Having now particularly described and ascertained 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. In a ball bearing having more than two, rows of balls the combination of one
or more collars such as F and one or more cones such as G, one keyed to the
casing and the other to the axle and both adapted to move laterally thereon, with
end cones one of which serves as a stationary abutment and the other as a means
of adjustment for the whole bearing.
2. A ball bearing having in combination three or more rows of balls at its one
end and a single row at its other end, a casing with internal flanges such as d, d',
fixed cups or paths such as E, E' and cups and cones such as F, G secured
respectively to the casing and the axle but adapted to move laterally thereon, and
means for effecting the adjustment of the bearing by one mechanical operation
substantially as set forth.
3. The construction and arrangement of parts constituting my improved bearing
substantially as set forth.
