PROVISIONAL SPECIFICATION.
Improvements in Treads for Stairs, Coal Plates, and like Covers
and other Surfaces Subjected to Foot Traffic.
1, JESSE RUST, of Garden Wharf, Battersea, in the County of London,
Manufacturer, do hereby declare the nature of this invention to be as
follows:-
--
This invention relates to the manufacture of improved stair treads, covers or
lids for openings in pavements, and other surfaces subjected to foot traffic.
In carrying out my invention I provide a metal frame of the required size, and
place the same face downwards on a plate or slab. I then fill in the frame with
tesseræ of suitable vitreous or ceramic ware and pour molten lead over the
whole surface so as to fill in the spaces between the tessera and to form a
backing.
By this means the tessera are thoroughly bound together and the combined
surface of tesseræ and lead forms a tread which possesses the advantages of
durability and non-slipperiness, and one which can be easily kept clean.

Improvements in Treads for Stairs, Coal Plates, and like Covers
and other Surfaces Subjected to Foot Traffic.
I, JESSE RUST,. of Garden Wharf, Battersea, in the County of London,
Manufacturer, do hereby declare the nature of this invention and in what
manner the saine is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention relates to the manufacture of improved stair-treads, covers or
lids for openings in pavements, and other surfaces subjected to foot traffic.
In carrying out my invention I provide a metal frame of the required size, and
place the same face downwards on a plate or slab. I then fill in the frame with
tesseræ of suitable vitreous or ceramic ware and pour molten lead over the
whole surface so as to fill in the spaces between the tesseræ and to form a
backing.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is a cross section of a stair-tread constructed according to my
invention, and,
Figures 2 and 3 are similar views illustrating modifications of my invention.
Similar reference letters indicate corresponding parts throughout the drawing.
a is the metal frame which, as shewn in the drawing, is shaped at one edge to
form the edge of a stair-tread but which may be otherwise shaped according to
the particular purpose for which my invention is required. b, bare the tesseræ,
and c is the filling and backing for retaining the tesseræ in place.

page_text: As shewn in Figure 1 the tread is represented as being made in the manner
hereinbefore indicated, that is to say, the frame a and the tesseræ b, b are
placed face downwards upon a plate or slab d and then a filling of lead is
poured over the whole to fill in the spaces between the tesseræ and to form a
backing.
In the arrangement shewn in Figure 2 the lead is only used for partially filling
the spaces between the tesseræ, the remainder of the spaces and the backing being
formed of cement. When this filling and backing of two materials is employed,
I may place the frame right way up, as shewn in Figure 3, and then partly fill
the same with cement and bed the tesseræ thereon, the spaces between the
tesseræ not filled with cement being filled with lead.
It will be obvious that whichever mode of construction is adopted the result is
the same, that is to say, a surface is produced composed of tesseræ the spaces
between which are of lead.
By the means herein before described the tesseræ are thoroughly bound
together and the combined surface of tessera and lead possesses the advantages
of durability and non-slipperiness, and is also one which can easily be kept
clean.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. Stair-treads and other articles or covers the surfaces of which are subjected
to foot traffic, composed of a number of tesseræ of vitreous or ceramic ware the
spaces between which are filled in with lead in such a manner that a combined
surface of tesseræ and lead is produced substantially as described.
2. Stair-treads and other articles or covers the surfaces of which are subjected
to foot traffic, composed of a series of tesseræ arranged in a frame and filled in
and backed with lead, or with lead and cement, substantially as hereinbefore
described.
3. The manufacture and use of stair-treads, coal plates and like covers and
other surfaces subjected to foot traffic substantially as hereinbefore described and
illustrated in the accompanying drawing.
