HIDING OR FILLING UP RE-ENTERING OR CONCAVE CORNERS OR ANGLES, SUCH
AS THE CORNERS OR SKIRTINGS OF ROOMS OR STAIR-CASES." A communication
from abroad from Duncan McFee and Robert Arthur Kellond, of the City of
Montreal, and Donald Eden McFee, of Lennoxville, both in the Province of Quebec,
in the Dominion of Canada.
This Invention is designed to provide a means whereby corners or internal
angles caused by the junction of two vertical surfaces with a horizontal plane
may be shielded or filled up, in such a manner as to prevent the accumulation of
dust and dirt, and allow the same to be easily cleaned, the Invention being specially
adapted to and intended for the angles of skirtings or bases of rooms, of stair-cases,
window linings, et cetera, and while efficiently fulfilling its purpose as above will
render ornamental and improve the appearance of the corner in which the shield
is placed.
'
It may be described as a triangular plate, usually and preferably equilateral,
formed with a regular internal curve and concave edges.
This plate is cut or stamped out of thin metal or any suitable material, and bent
by swaging or pressing in dies, preferably into such a shape that a line drawn
from either of the apices through the centre will give an equal and the same
curve.
The shield is secured after having been set in place by driving in the points of
the triangular plate (these points having been previously turned over), but it must
be understood that it can be fastened into the corner in any desired way by pins,
or screws, or even by cementing.

page_text: The concavity of the edges allows the plate to fit so closely against each of the
surfaces as to make a dust proof joint.
In cases where the vertical meeting surfaces are to each other at an angle
greater than a right angle, the shape of the plate will be modified accordingly.
To render the shields highly ornamental they may be plated with any suitable
metal or their surfaces painted or grained, as found desirable.
Similar shields can also be used, if desirable, to fill a corner formed by the
intersection of two planes at right angles. In such case the shield is a long strip
stamped out with points on each edge bent over so as to enter holes pierced
for the purpose. This however will not be found so useful as the triangular shield, 1
as it can only be applied where carpets are not required to be laid down.
