1 ALFRED DICKINSON of Darlaston in the County of Stafford, Tramway Manager
do hereby declare the nature of my invention for "IMPROVEMENTS IN AXLE BOXES "
to be as follows:-
My invention consists of an axle box with cylinder so annexed thereto or produced
therefrom that it shall work upon another and smaller cylinder around the axle.
This inner cylinder may form part of the boss of the wheel or may be fixed around
the axle outside such boss. The inner cylinder acts as a piston within the outer
cylinder of the axle box so far as to permit the play of the axle within the axle box
but being affixed to the axle or the boss of the wheel as aforesaid the inner cylinder
or piston of necessity revolves with such axle and wheel and within the outer cylinder
of the axle box. To secure a perfect fitting of the parts the surface of the inner
cylinder may be fluted or grooved with rings of suitable material sprung into the
grooves and the axle box thus made impervious to the finest dust.
Dated this Third day of November 1886.
ALFRED DICKINSON.

page_text: I ALFRED DICKINSON of Tramway Depot Darlaston in the County of Stafford
Tramway Manager do hereby declare the nature of my said invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement:
This invention consists of an axle box with cylinder so annexed thereto or produced
therefrom that it shall work upon another and smaller cylinder around the axle.
This inner cylinder may form part of the boss of the wheel or may be fixed around
the axle outside such boss. The inner cylinder acts as a piston within the outer
cylinder of the axle box so far as to permit the play of the axle within the axle box but
being affixed to the axle or the boss of the wheel as aforesaid the inner cylinder or
piston of necessity revolves with such axle and wheel and within the outer cylinder of
the axle box. To secure a perfect fitting of the parts the surface of the inner
cylinder may be fluted or grooved with rings of suitable material sprung into the
grooves and the axle box thus made impervious to the finest dust.
In order that my invention may be clearly understood and easily carried into
practice I have illustrated one form thereof upon the accompanying sheet of drawings
which will be sufficient to enable practical men to apply the principle to other
conditions.
Figure 1 is a longitudinal sectional elevation of an axle box A upon the end of
an axle F.
Figure 2 is a cross section of the same axle box and axle.
My axle boxes are constructed with a cylinder or internal recess a¹ at the wheel end
thereof and the axle F has fixed upon by keying, shrinking or otherwise the collar D
the outside of which is turned to fit and turn in the cylinder a¹ of the axle box A.
To secure a constant fit between the internal cylinder or collar D and the internal
part of a¹, I use one or more spring rings E which is or are sprung into the recess d¹
(or recesses as the case may be) of the collar D and thus the box is secured against
the entrance of dust. The bearing B may be removed or examined at any time by
taking off the door (which otherwise seals the front end of the axle box. The
lubrication is effected by the pad G which is supported upon a tin or other frame
and kept to its work by suitable springs g¹ and g².
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 :-
The improved grit proof axle box formed to embrace the inner cylinder or collar D
substantially as and for the purpose herein set forth.
