PROVISIONAL SPECIFICATION.
Improvements in Bearings for the Axles of Railway Vehicles and
for other like purposes.
I, JOHN BERKLEY of 12 Warwick Street, West Heaton, Newcastle-on-Tyne,
Ironmonger, do hereby declare the nature of this invention to be as follows:-
My invention consists of improvements in bearings for the axles of railway
vehicles, the shafts of screw propellers, and for other like purposes, and has special
reference to bearings of the roller type.
I,
According to my invention I construct the rollers with alternate circumferential
convex and concave parts or sections, so that they shall come into contact with
their axles, shafts or spindles only at the convex parts. These parts are rounded
or bevelled off at the sides so as to reduce the friction. also construct the rollers
with rounded or egg-shaped ends so as to reduce the friction against the sides
of the box or case in which they revolve. These rollers are arranged parallel to
and in contact with each other around the axle shaft or spindle. If the axle or
shaft is fixed to the wheel the bearing will be attached to the vehicle or other
corresponding part, but if the axle or shaft is stationary the bearing will be placed
in the centre of the wheel. The box or case containing the rollers is cylindrical
and of such diameter that the rollers just fit into the annular space between it and
the axle or shaft. The box should be filled with oil or other lubricant up to about
the level of the bottom of the axle or shaft so that the lower rollers revolve in the
lubricant and every one therefore receives a fresh supply at every revolution. In
order to prevent waste of oil a leather or other collar or washer is fitted at each
side of the box in close contact with the axle or shaft.

COMPLETE SPECIFICATION.
Improvements in Bearings for the Axles of Railway Vehicles and
for other like purposes.
I, JOHN BERKLEY of 12 Warwick Street, West Heaton, Newcastle-on-Tyne,
Ironmonger, 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 invention consists of improvements in bearings for the axles of railway
vehicles, the shafts of screw propellers and for other like purposes, and has special
reference to bearings of the roller type.
According to my invention I construct the rollers with alternate circumferential
convex and concave parts or sections so that they shall come into contact with their
axles, shafts or spindles only at the convex parts. These parts are rounded or
bevelled off at the sides so as to reduce the friction. I also construct the
rollers with rounded or egg shaped ends so as to reduce the friction against
the sides of the box or case in which they revolve. These rollers are arranged
parallel to and in contact with each other around the axle shaft or spindle. If the
axle or shaft is fixed to a wheel the bearing will be attached to the vehicle or other
corresponding part, but if the axle or shaft is stationary the bearing will be placed
in the centre of the wheel or rotating part. The box or case containing the rollers

page_text: is cylindrical internally and of such diameter that the rollers just fit into the
annular space between it and the axle or shaft.
The box should be filled with oil or other lubricant up to about the level of the
bottom of the axle or shaft so that the lower rollers revolve in the lubricant and
every one therefore receives a fresh supply at every revolution. In order to
prevent waste of oil a leather or other collar or washer may when thought necessary
be fitted at each side of the box in close contact with the axle or shaft.
The accompanying drawings represent by way of example the application of my
invention to several purposes. Figures 1 and 2 show it as arranged for the axles
of railway rolling stock and tramcars; Figures 3 and 4 as arranged for propeller
shafts Figures 5 and 6 as arranged for plummer blocks and Figures 7 and 8 as
arranged for the wheels of carriages for common roads. The same letters of
reference indicate corresponding parts in all the figures. a represents the axle,
shaft or journal; bb are the rollers which constitute the bearings. These rollers are
constructed with circumferential convex parts which come in contact with the axles,
shafts or journals, the said convex parts being rounded or bevelled off as shown so
as to reduce the friction. The other portions of the circumference of the rollers
are concave and do not come in contact with the axles, shafts or journals. The
rollers also have rounded or egg-shaped ends as shown so as to reduce the friction
against the sides of the box or case in which they revolve. c is the box or case
cylindrical internally in which the rollers bb are arranged parallel to and in contact
with each other around the axle, shaft or journal a. dd are apertures for supplying
oil or other lubricant to the box c which should be filled up to nearly the level of
the underside of the shaft a so that the rollers which are at the bottom of the case
revolve in the lubricant and every one therefore receives a fresh supply at every
revolution.
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 :-
In a bearing for the axle of a railway vehicle or for other like purpose, a set of
rollers having rounded or bevelled convex parts at their circumference and rounded
ends, the said rollers being arranged in a cylindrical box or case and parallel to and
in contact with each other around the axle, shaft or spindle, substantially as
herein before described.
