page_text: I, GEORGE BONEHILL of 107 Grosvenor Street, Oxford Road, Manchester, in tho
county of Lancaster, Brass Finisher, do hereby declare the nature of this Invention
to be as follows:-
:-
My invention consists of an improved method of constructing wearing surfaces.
applicable for the purposes as set forth in the title hereto.
The wearing parts of such surfaces I make of Indian rubber, wood, glass or
other suitable material and such wearing parts may be in the form of strips,
rectangles, squares, circles, ovals, letters of the alphabet, numerical figures, or in any.
other shape or formn desired.
I make the sides or edges of the said parts to slope inwards so that the base is
wider than the upper surface, or I may form a flange or fillet around the base to
have the same effect.
I cut or stamp a metal plate in such a manner, that small portions can be bent or
turned up to project at an angle above the surface, such portions being bent at such
an angle and so arranged that they will retain the wearing parts securely in
position upon the said plate.
In certain cases it may be necessary to bend the said cut portions quite vertically
in order to place the wearing parts therein, and then bend them partly back to fix
the said wearing parts.
I prefer to groove, corrugate or otherwise suitably form the upper surface of the
wearing, parts in order to increase the security of the foothold, and such wearing
parts are so disposed on the surface of the plate that they alone come into contact
with the feet.
Wearing surfaces made according to my invention afford good foothold, are easily
cleaned and the wearing parts can be readily replaced when worn.

page_text: I, GEORGE BONEHILL of 107 Grosvenor Street, Oxford Road, Manchester in the
county of Lancaster Brass Finisher, 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:-
My invention consists of an improved method of constructing wearing surfaces
applicable for the purposes as set forth in the title hereto.
In the accompanying sheet of drawings, Figure 1 is a vertical section through the
line X X in Figure 2, and Figure 2 is a plan of part of the "tread" of a staircase
having my improved wearing surface applied thereto.
Figures 3 and 4 are cross sections of parts of my improved wearing surface shewn
to an enlarged scale.
Similar letters refer to similar parts throughout the figures.
The wearing parts of the surface consist of blocks A, formed preferably of
Indian Rubber. The sides or edges of these blocks slope inwards as shewn clearly
at B in Figures 1 and 2 and in the enlarged sectional view of a block in Figure 3,
so that the base is wider than the upper surface. In place of these inclined edges
the blocks may be formed, if desired, with a flange or fillet C around the edge, as
The
shewn in Figure 4. A metal plate D forms the foundation for the blocks A.
said plate is cut or stamped in such a manner that small portions E can be bent or
turned up to project at an angle above the surface in order to retain the blocks A
securely in position upon the plate D.
In certain cases it may be necessary to bend the said cut portions E quite
vertically, in order to place the blocks therein, and then bend them partly back to
fix the said blocks.
The blocks are preferably grooved or corrugated on their upper surface, as shewn,
in order to increase the security of the foothold, but I do not confine myself to the
precise number or shape of the grooves or corrugations shewn.
The blocks A are so disposed on the surface of the plate D, that they alone come
into contact with the feet, and when the said blocks become worn they can readily
be removed and new ones inserted, without disturbing or taking up the plate D.
Wood, glass or other suitable material as well as Indian Rubber may be used for
the blocks A, glass being especially applicable in cases where light is required to be
admitted through the wearing surface, as for instance in the case of pavement
lights over cellars or basements.
The blocks A, may not only be in the form of short rectangular strips, as shown,
but they may be in the shape of squares, circles, ovals, letters of the alphabet,
numerals, or other desired patterns, provided that their edges be in all cases Bo
shaped as to be securely held by the bent portions E of the plate D.

page_text: The drawings, although only shewing the application of my invention to the
surface of a staircase " tread," will clearly explain how flooring, mats, and other
similar surfaces may in like manner be treated.
The plate D may be fastened in position by means of screws, nails, or other
suitable devices.
A mat made according to my invention may consist simply of the plate D and
blocks A, or it may have a frame or plate of wood or other suitable material
attached to the underside of the plate D, if desired.
Wearing surfaces made according to my invention afford good foothold, are easily
cleaned and the wearing parts can be readily replaced when worn.
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:-
(1)-The improvements in the manufacture of stair-nosings, mats, flooring and
other wearing surfaces from sheet or other metal, substantially as herein set forth.
(2)-In the construction of wearing surfaces for stairs, mats, flooring and other
like purposes, the use of a metal plate D, having projections E formed thereon,
substantially as and for the purposes herein set forth.
