Stook.
I, HAROLD IMRAY, of No. 28 Southampton Buildings, Chancery Lane, in the
County of London, Chartered Patent Agent, do hereby declare the nature of this.
invention to be as follows:-
This invention relates to a construction of dust shield for axles of railway rolling
stock in such a manner as, not only to prevent access of dirt and grit, but also to
prevent issue and waste of oil.
Fig. 1 of the accompanying drawings is a section of the back part of the axle
box shewing the dust shield and axle in place; Fig. 2 is a sectional plan of the
same, Fig. 3 is a front view of the plate of the shield, and Fig. 4 is a section on X X
of Fig. 3.
A plate A of suitable metal, such as galvanised iron, is formed with a hole fitting
the axle and around the hole a flange B turned back so as to be at an acute angle
with the surface of the plate. Parts C of the plate are punched so as to
project as spring tongues on the other side of the plate.
The axle box is made with an internal recess D which on the upper side is open
and is covered by a plate E. The plate A is introduced through the opening into
the recess D, and then a wooden plate F, having a hole through it for the axle, is
pushed down behind the plate, the springs C pressing the wood back and the plate
forward. The axle box with the dust shield in place is then put upon the axle.
The flange B catches most of the oil that might otherwise leak out past the shield,
and returns it to the axle box.

Stock.
I, HAROLD IMRAY, of No. 28 Southampton Buildings, Chancery Lane, in the
County of London, Chartered Patent Agent, 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 :-
This invention relates to a construction of dust shield for axles of railway rolling
stock in such a manner as, not only to prevent access of dirt and grit, but also to
prevent issue and waste of oil.
Fig. 1 of the drawings accompanying my Provisional Specification is a section of
the back part of the axle box shewing the dust shield and axle in place; Fig. 2 is

page_text: a sectional plan of the same, Fig. 3 is a front view of the plate of the shield, and
Fig. 4 is a section on X X of Fig. 3.
A plate A of suitable metal, such as galvanised iron, is formed with a hole fitting
the axle and around the hole a flange B turned back so as to be at an acute
angle with the surface of the plate. Parts C of the plate are punched so as
to project as spring tongues on the other side of the plate.
The axle box is made with an internal recess D which on the upper side is
open and is covered by a plate E. The plate A is introduced through the
opening into the recess D, and then a wooden plate F, having a hole through it
for the axle, is pushed down behind the plate, the springs C pressing the wood
back and the plate forward. The axle box with the dust shield in place is then put
upon the axle. The flange B catches most of the oil that might otherwise leak out
past the shield, and returns it to the axle box.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
A dust shield for an axle of railway rolling stock consisting of a front metal
plate made with a hole having its edge inwardly flanged, and with spring tongues
in combination with a wooden back plate, substantially as described.
