COMPLETE SPECIFICATION.
An Improved Non-slipping Tile or Tread for Floor or Stair Surfaces
and like purposes.
We, ALFRED JOHNSON, and FREDERICK GEORGE JOHNSON, of Trent Works,
Hanley, Staffordshire, Pottery Manufacturers, 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 refers to tiles of some durable material such as stoneware semi-
porcelain, iron-stone or the like which are inserted in or laid on the wearing
surfaces of stairs or floors and especially in sanitary buildings and for similar
purposes; and consists of a narrow piece of such material of special section,
adapted for inserting in grooves or channels formed in or on such surfaces and
which can be fixed therein by means of cement or in any suitable manner.
The ordinary dimensions of these tiles would be nearly as follows, but we do
not bind ourselves to any particular size as they would probably be made in
various sizes:-height about one inch, width at top about three quarters of an
inch to one inch, at bottom about one inch to one and a half inches.
Our improved tiles are designed to project somewhat from the floor so as to
afford a secure foothold and are intended to be laid in parallel lines or rows at
suitable distances from each other. The space between them may be filled up
with flat tiles, stone, wood or any other suitable material.
We will now describe the invention with reference to the accompanying draw-
ings in which:—
Fig. 1 shows a sectional elevation of a step in which four of the tiles are shown
embedded.
Fig. 2 shows a sectional view of one tile in position on a step or floor.
a is the body of a step into which the tiles are inserted.
b is a recess for cement of dovetailed section within the tile c. On the top of
the tile is formed the rounded face d which is curved as shown. The block is
made with sloping sides as shown and is firmly secured in place by cement at e
the channel in the step being made with vertical sides.
The mode of fixing is as follows:-
The hollow space beneath the tile is filled with cement and the tile is then
laid in the groove or channel formed to receive it. Cement is then laid in the
spaces e on each side of the tile, the top being allowed to project above the
level of the step or floor, shown in the drawing. In this way complete immunity
from slipping with great durability are obtained.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
1. A tile or tread for taking the wear of stairs or floors and preventing slipping
thereon, as herein described and set forth.

page_text: 2. In a tile or tread for stairs, floors or the like the special section of strip or
ridge, of stone-ware, porcelain, semi-porcelain vitreous or other similar material,
as herein described, and set forth.
Dated this 11th day of August 1898.
