PROVISIONAL SPECIFICATION.
Improvements in Treads for Floors, Stairs, and the like
We JONATHAN MASON and JOSEPH MASON Contractors of 15 Barbican in the City
of London, and WILLIAM SQUIRES CODNER Iron Merchant of 10 Queen Elizabeth
Walk Stoke Newington in the County of Middlesex do hereby declare the nature of
this invention to be as follows:―
This invention relates to certain improvements in treads for floors, stairs and the
like the object being to combine chilled steel or iron or other metal in combination
with lead, fibre of this or that kind, india-rubber or composition, so as that there shall
bè provided a combined wearing surface of different material the one surface serving
as means for holding or keying the flooring or treads together and at the same time
providing antiwearing surfaces-whilst the other or softer material presents a non-
slipping and noiseless or deadened footing or foothold surface.
In carrying this invention into effect we proceed as follows:-
According to one construction bars or pieces of metal are employed laid upon the
tread, flooring, or proper surface to be covered or secured at intervals by screws
dowels or other convenient or available means and between the bars or pieces of metal
are laid the softer material. For instance taking a rolled bar or strip or pieces of
lead formed with lower expanded portion or flange a metal bar or pieces with
corresponding upper expanded portion or flange will be laid alongside of the softer
material and so on row after row or pattern by pattern, according whether the fixing
metal pieces be in bars or pieces.

We JONATHAN MASON and JOSEPH MASON, Contractors of 15 Barbican in the City
of London and WILLIAM SQUIRES CODNER Iron Merchant of 10 Queen Elizabeth's
Walk Stoke Newington in the County of Middlesex 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 follo wing statement:-
This invention relates to certain improvements in treads for floors, stairs, and the
like, the object being to combine chilled steel or iron or other hard metal with lead,
fibre (of this or that kind) indiarubber, or composition, so as that there shall be
provided combined wearing surfaces of different material the one surface serving as
means for holding or keeping the flooring or treads together and at the same time
providing antiwearing surface whilst the other or softer material presents a non-
slipping and noiseless or deadened footing or foothold surface.
In carrying this. invention into effect we proceed as follows:-
According to one construction bars or pieces of metal are employed, laid upon the
tread flooring or proper surface to be covered and secured at intervals by screws,
dowels or other convenient or available means and between or in the bars or pieces of
metal is laid the softer material.

page_text: For instance taking a rolled or cast bar or strip or pieces of lead formed with
lower expanded portion or flange a harder metal bar or pieces with corresponding
upper expanded portion or flange will be laid alongside of the softer material and so
on row after row or pattern by pattern according whether the fixing metal pieces be
in bars or pieces.
In order that the invention may be clearly ascertained we have annexed herewith a
sheet of drawings wherein Fig. 1 is an isometric view of a tread for a stair fitted
according to this invention and Fig. 2 is a sectional side view taken at line A. B
of Fig. 1. but upon larger scale. Fig. 3 to 5 illustrate modifications of applications
of the invention.
a represents hard metal strips prepared with openings expanded above and below
from the centre b, so as to constitute means of holding the filled in and expanded
lead pieces or buttons c. The buttons or pieces c are in this case expanded both
above and below the harder metal so as to hold in both directions. In making these
buttons the lead may be cast with a surface which will be approximately such as it
shall be when inserted in the harder metal but with a shank piece which will pass
through the openings b of the harder metal and then be hammered out to expand the
softer metal say on the under side or it may be the upper side or both.
In the arrangement shown in Fig. 3 there are combined strips made up as in Figs. 1
and 2, a being the harder metal c buttons of expanded lead c¹an intermediate row of
lead blocks or it may be a strip expanded at c², below the overlapping portion a¹ of
the harder metal. d is a filling of any required kind to make up the height of the
expanded portions c², or in a modified form the parts a¹, and d may be of a piece of
and with the harder metal a. The intermediate rows c¹ may be of alternate pieces
of harder or softer material.
Fig. 4 represents a modified form of the softer material the expanded portion c²
being expanded and formed at an angle. These may be in strips or blocks as before
described in reference to Fig. 3 and as shown in Fig 5,--in this fig. the filling d is
not used,
According to a modification we may make the intermediate strip or blocks c¹
between the continuous buttoned strips as shown in Figs. 1 and 2 of other softer
material than lead such as india-rubber or wood, or it may be of blocks of such
material placed side by side or placed in alternation with metal whether soft or hard.
The arrangement is convenient for laying out broad surfaces and in conveying the
material to the spot at which it has to be laid the lead buttoned strips or sheets
alternating with the intermediate rows c¹.
The strip shown upon the lower tread of Fig. 1. represents the softer metal pieces c,
of different form to those shown on the upper tread and although the harder metal
strips are shown with longitudinally corrugated roughings this may not always be
followed, as a pointed-square,or diamond form of roughing of the harder metal surface
may be adopted but furnished with the buttons c.
These treads may be employed as coverings for hall floors entrance ways and
passages, stairs, and stairways, coverings to sewer holes, hydrant boxes, cellar
coverings, coal-shoot covers, telegraph wire boxes in streets and such like
and for such may be made up in a proper framing for placing the covers in
position.
The hardened metal strips or sheets provided with the lead buttons may be of
brass or other similar alloy of the metals giving the requisite hardened antiwearing
surface.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The improvements in treads for floors stairs, coverings and the like combined and
daahad in nafananan to and shown be the manastira fioun of

page_text: Secondly: In treads as herein specified the strips sheets or pieces of chilled or
hardened metal combined with the lead buttoning as set forth.
