Improvements in the Application of Ball-bearings to the Wheels of
Vehicles.
I, JOHN PUGSLEY, of Shaftesbury Street, in the County Borough of Newport,
Blacksmith and Wheelwright, do hereby declare the nature of this invention to
be as follows:-
This invention relates to the application of ball-bearings to the axles of the
wheels of carts, carriages, trucks and other vehicles, the object being to reduce the
friction and wear incidental to the bearings usually employed, easier running of
such vehicles resulting.
In carrying out my invention, I fit onto an ordinary axle two concave cones of
hardened steel. These cones are placed upon the axle so that they cannot revolve
by flattening the axle on one side and making a corresponding flat surface in the
hore of the cones. The cones are disposed a suitable distance apart, according to the
size of the axle-box, and with their concave surfaces facing each other. I then take
an ordinary iron axle-box, and, having turned out a portion of the bore at each end,
I fix therein two cups of hardened steel having concave inner surfaces which corre-
spond to and fit over the cones on the axle, and into the intervening space between
the two concave surfaces a number of small steel balls are placed the latter taking
the whole bearing of the wheel. The cups and cone on the inner side, or that side
nearest the vehicle, is fixed at the extreme end of the axle-box, while the other cup
and cone are situate a short distance within the outer end of the axle-box; the space
thus left between the bearing and the end of the axle-box serving to accommodate
an adjusting nut for regulating the bearing. For this latter purpose, the axle is
tapped with a right-hand thread whereon is screwed a nut the inner side of which
bears against the cone on the axle. Outside this nut the axle is reduced slightly
and tapped with a left-hand thread on which fits a lock-nut for locking the adjust-
ing nut. The end of the axle-box may be covered by a cap whereby the ingress
of dust or dirt to the parts of the bearing is prevented.

I, JOHN PUGSLEY, Wheelwright & Smith, Shaftesbury Street, Newport, Mon.,
do hereby declare the nature of this invention and in what manner the same is to
[Price 8d.1

statement—
This invention relates to the application of ball bearings to the axles of wheels
of carts, carriages, trucks, and other vehicles, the object being to reduce the friction
and the wear incidental to the bearings usually employed, the easier running of
such vehicles resulting. In carrying out my invention I fit to the axle A, two con-
cave cones of hardened steel B, B. These cones are placed upon the axle so that
they cannot revolve. The cones are disposed upon the axle a suitable distance
apart according to the size of the axle box and with their concave surfaces facing
each other. [This cone C may be made separate from the box D which is usually
made of cast iron or C & D may be one solid piece of steel or other metal.] I fix
therein two cups of hardened steel C having concave inner surfaces
which correspond to and fit over the cones on the axle, and into the
intervening space, between the two concave surfaces of B & C a number of small
steel balls are placed E, the latter taking the whole bearing of the wheel. The
cups and cones situated on the outer end of the axle box are of sufficient distance
from the end of the axle to accomadate an adjusting nut G for regulating the
cones B B to CC as required to take up wear. A lock nut H is provided to keep
the adjustment safe screwed upon a reduced part of the axle F.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
(1) Reduction of friction incidental to pressure of weight on axle.
(2) Simplicity of construction of the working parts.
(3) Durability of working parts conbined with accessibility for renewals.
(4) Adjustment of working parts to take up wear.
