PROVISIONAL SPECIFICATION.
A Dust and Dirt Shield for Corners of Stairs, Rooms, and the like.
CHARLES ARLISS 31 Museum Street London W.C. Letterpress Printer do
hereby declare the nature of this invention to be as follows:-
This invention is for the prevention of the accumulation, of dust and dirt in
the corners of stairs, steps, rooms, cupboards, drawers, &c., but more especially
for application-to wooden staircases and rooms with boarded flooring. It may
be briefly described as follows:--
It is a piece of sheet brass, iron, copper, or other suitable metal of a trian-
gular shape its edges being slightly hollowed, it is stamped in a mould so that
it becomes concave on one side and convex on the other, the moulding being
equal to the hollowing of the edges. This plate when fixed in the angle of a
stair, formed by the stair-tread, the rise and the wall or end it will effectually
prevent any accumulation of dust or dirt, as it completely covers the corner
and presents only a slightly concave front, which is easily cleaned or brushed.
It is intended to apply the plate to all similar corners for the same dust and
dirt preventing purpose, and to fix the plate in position by means of screws,
nails or other suitable means.
In addition to the moulding I propose embossing the plate in such a manner
as shall ensure the amount of rigidity necessary.

A Dust and Dirt Shield for Corners of Stairs, Rooms, and the like.
CHARLES ARLISS 31 Museum Street London W.C. Printer 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 is a shield made of metal or other suitable substance and is
intended for the prevention of the accumulation of dust and dirt in the corners
of rooms, cupboards, stairs, steps, drawers and the like, and is also intended to
be an ornament when fitted to corners as hereinafter described.
It consists of a piece of sheet brass, copper, iron tin or other suitable substance
of a triangular shape, its edges being slightly hollowed. It is stamped in a
mould so that it becomes concave on. one surface and convex on the other
surface, this moulding being proportional to the hollowing of the edges. It is
also embossed with a reeding near its edges and a figure of a star, or other
design for the purposes of keeping it rigid and making it ornamental in
appearance. This plate when fixed in the corner of a stair, formed by the rise,
tread and the wall or side, will effectually prevent any accumulation of dust or
dirt, as it completely covers the corner, and presents only a slightly concave
front which is easily cleaned or brushed.
It is intended to fix the shield in position by means of a nail or screw, or other
suitable means, a hole being made in its centre for the passage of the nail or screw.
In the accompanying drawing
.
Fig. 1 represents the shield full size, A is the embossed figure, C the hole for the
nail or screw and D is the reeding already described. Fig. B shows the application
of the shield to a stair corner.
