Complete Specification Left, 12th July, 1894-Accepted, 18th Aug., 1894
PROVISIONAL SPECIFICATION.
Improvements in Axle Boxes for Rolling Stock.
1, GEORGE WILSON of Thirteen Victoria Street in the City of Westminster
Civil Engineer do hereby declare the nature of this invention to be as follows:-
The invention consists in forming on the back of the bearing or the inside of the
crown of axlebox, where the bearing takes its seat, a transverse ridge or projection,
angular or rounded, or the back of the bearing or its seating may be curved so as
to enable the bearing to accommodate itself to any angle of the axle, the oscillation
being lengthways of bearing. This projection fits, with a certain amount of side
play, into a similar shaped recess so as to take the longitudinal thrust of axle, or if
the back of bearing or its seating is curved the bearing is then formed with a small
projection at its sides or ends so that it may not be displaced longitudinally with
the thrust of axle.
The axlebox and bearing may be of the usual pattern the only difference being
the formation of a ridge and a corresponding recess or the curving of the back of
bearing or its seating so as to enable the bearing to rock lengthways in its place.

1, GEORGE WILSON of Thirteen Victoria Street in the City of Westminster
Civil Engineer 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 :-
The invention consists in forming on the back of the bearing or the inside of the
crown of axlebox, where the bearing takes its seat, a transverse ridge or projection,
angular or rounded, or the back of the bearing or its seating may be curved so as
to enable the bearing to accommodate itself to any angle of the axle, the oscillation
being lengthways of bearing. This projection fits, with a certain amount of side
play, into a similar shaped recess so as to take the longitudinal thrust of axle, or if
the back of bearing or its seating is curved the bearing is then formed with a small
projection at its sides or ends so that it may not be displaced longitudinally with the
thrust of axle.
.
The axlebox and bearing may be of the usual pattern the only difference being
the formation of a ridge and corresponding recess or the curving of the back of
bearing or its seating so as to enable the bearing to rock lengthways in its place.
In order that my invention may be more readily understood I have attached
hereunto a sheet of drawings to which I will now refer.
In the said drawings-
Figure 1 is a longitudinal section of an axlebox shewing the bearing with a curved
ridge or projection on its back and fitting with a certain amount of play into a
similar shaped recess in the crown of axlebox thereby allowing the bearing to
Oscillate lengthways.

page_text: Figure 2 is a cross section of an axlebox shewing that the ridge or projection on
back of bearing extends across the back so that there can be no movement or
oscillation sideways.
A is axlebox.
D the ridge or projection on back of bearing.
E the recess in crown of axlebox.
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 :-
So forming a bearing that it is free to oscillate longitudinally in its seating by
curving the back of bearing or its seating or forming on either a ridge or projection
so as to allow the bearing to accommodate itself to any angle of the axle.
Dated this Tenth day of July 1894.
