Improvements in White Edged Copings or Slabs for Railway
Platforms and the like.
I, EDWIN BREADNER, of Ogden's Chambers, Deansgate, Manchester, in the
County of Lancaster, Engineer do hereby declare the nature of this invention
to be as follows:-
0.
It consists in certain improvements upon my invention described in the Speci-
fications of my Letters Patent No. 6190 dated March 26th 1895, and consists in
means for forming a more durable white edge than is therein described.
It consists in making the white edge in small slabs or tiles of ironstone or other
suitable pottery. or earthenware and afterwards adding the concrete backing so
as to form the rest of the slab or coping, or in some cases the white slabs may be
attached to the edges of stone slabs either in situ or before laying, or to the edges
of wooden platforms.
The best combination for the white tiles consists of ironstone, china and other
clays in suitable proportion, hardfired, and in the biscuit" or bisque condition.
Dated this 3rd day of May 1899.

Improvements in White Edged Copings or Slabs for Railway
Platforms and the like.
I, EDWIN BREADNER, of Ogden's Chambers, Deansgate, Manchester, in the
County of Lancaster, 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: -
It consists in certain improvements upon my invention described in the Speci-
fications of my Letters Patent No. 6190 dated March 26th 1895 and consists in
means for forming a more durable white edge than is therein described. It con-
sists in making the white edge in small slabs or tiles of ironstone or other suitable
pottery or earthenware and afterwards adding the concrete backing so as to form
the rest of the slab or coping, or in some cases the white slabs or tiles may be
attached to, the edges of stone slabs in situ or before laying, or to the edges of
wooden platforms.
The white slabs or tiles I compose of the usual foundation of ball or black clay

page_text: mixed with the usual sands, to this I add a sufficient quantity of powdered iron-
stone to give it density and strength. I then obtain the necessary whiteness by
mixing with the foregoing a sufficient quantity of china clay and flint. These
ingredients are mixed, pressed in a suitable mould, and dried in the usual manner.
The tiles are then hard fired in one operation and are then ready for use, being
left in the biscuit" or bisque condition.

The concrete back is then added either by using a mould, in the manner
described in the specifications to my previous patent, the tiles in this case being
placed in the mould and the concrete added as described, or the concrete slab is
moulded with a suitable keyed recess upon its front edge into which the tiles are
afterwards cemented.
The tiles can also be attached in a similar manner to stone slabs in situ, or
before laying, or to wooden platforms, a suitable recess keyed or otherwise being
cut or formed in the stone or wood and the tiles inserted and cemented in place.
The tiles' may be formed with a suitable key or recess upon their under surface
to assist this operation.
Referring to the drawing sent herewith:-
:-
The figure shows a concrete slab a with a white edge formed of white tiles or
slabs the white tiles in this case being formed with a dovetail key c to strengthen
their hold upon the concrete slab a.
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:
1st. The improved white tile or slab, composed of the clays and other sub-
hereinbefore and in the accompanying drawings for the purposes set forth.
stances and made, substantially as, and in the manner, described and shown
2nd. The combination of the improved white tile or slab with a concrete slab
or foundation, substantially as described and shown, herein before and in the
accompanying drawings, for the purposes set forth.
3rd. The combination of the improved white tile or slab, with a stone or wood
foundation substantially as described and shown, herein before and in the accom-
panying drawings, for the purposes set forth.
Dated this 2nd day of March 1900.
