PROVISIONAL SPECIFICATION.
Improvements applicable to the Treads of Stairs, to Door-steps,
Landings, Flooring, and the like.
I, JAMES MELLING, of Dashwood House, New Broad Street, in the City of
London, Engineer, do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to improvements applicable to the treads of stairs to door-
steps, landings, flooring and the like.
In carrying out my invention I employ a perforated plate of suitable material
adapted to fit over flanged blocks of india-rubber or other suitable elastic material,
the said blocks passing through and projecting above the surface of the plate to
form the tread or wearing surface; the said blocks being held in position by the
perforations in the plate which also bears on the flanges of the blocks; the perfora-
tions on the plate are advantageously countersunk. The plate is fixed in position
by screws, hinges or in any other suitable manner which will allow of its being
raised or moved for the purpose of changing the position of or renewing the blocks
as they become worn.
In practice I find it best to form the parts of my blocks which pass through the
perforation of elliptical or circular shape in plan, the perforations in the plate being
of corresponding shape.

COMPLETE SPECIFICATION.
Improvements applicable to the Treads of Stairs, to Door-steps,
Landings, Flooring, and the like.
I, JAMES MELLING, of Dashwood House, New Broad Street, in the City of
London, 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 :-
This invention relates to improvements applicable to the treads of stairs, to door
and other steps, landings, flooring coal plates and the like.
In carrying out my invention I employ a perforated plate of suitable material
adapted to fit over flanged blocks of india-rubber or other suitable elastic material,
the said blocks passing through and projecting above the surface of the plate to
form the tread or wearing surface. The said blocks are held in position by the
perforations in the plate which also bears on the flanges of the blocks. The plate
is fixed in position by screws or hinges or is fixed in any other suitable manner
which will allow of its being raised or moved for the purpose of changing the position
of or renewing the blocks as they become worn.
In practice I find it best to form the parts of my blocks which pass through the
perforations of elliptical or circular shape in plan, the perforations in the plate being
of corresponding shape.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which :-
Figure 1 is a transverse section of a stair-tread having my improvements applied
thereto; and,
Figure 2 is a section on the line 2-2. Figure 1 :

page_text: Figure 3 is a plan view of a part of the stair-tread:
Figures 4 and 5 are a plan and elevation respectively of one of the flanged blocks
of india-rubber or the like; and,
Figures 6 and 7 are plan views of blocks of different shape :
Figure 8 is a plan shewing my invention applied to a carriage step; and,
Figure 9 is a section on the line 9-9, Figure 8 :
Figure 10 is a plan view shewing my invention applied to a coal-plate; and,
Figure 11 is a section on the line 11-11, Figure 10:
Figure 12 is a plan view drawn to an enlarged scale of one of the blocks shewn
in Figures 10 and 11; and,
Figure 13 is a section on the line 13-13, Figure 12.
Similar letters of reference indicate corresponding parts in the several figures.
a, a are the blocks of india-rubber or other clastic material provided with
flanges b, b, and c is the tread or foundation plate or sui face upon which the said
blocks are laid. dis the perforated plate by means of which the blocks a, a are
held in position.
The wearing surfaces of the blocks a, which may be of any suitable shape for
instance elliptical as shewn in Figures to 5, round as shewn in Figure 6, or square
as shewn in Figure 7, are laid upon the surface c and the plate d, which is provided
with perforations corresponding with the size and shape of the blocks a, a, is placed
over the said blocks so as to grip the flanges b, between itself and the surface c,
the plate being bent to cover the flanges or the edges of the tread or foundation
plate c. By this construction the blocks when worn can easily be removed from
and fresh ones inserted in the perforations.
When my invention is applied to stair-treads the plate d may be fixed in position
by screws e, e as shewn but it may be hinged at the back for convenience in
raising it.
When my invention is applied to a carriage step, as shewn in Figures 8 and 9,
the plate d is bent over so as to embrace the sides of the step, as shewn, the plate
being preferably fixed by means of a screw e having a nut f on the underside.
When my invention is applied to a coal-plate the blocks a, a which, as shewn in
Figure 10, are segmental in shape are provided with holes g, g to admit light and
in order to prevent water from entering the said holes balls h, h of glass are advan-
tageously inserted therein. The plate in this case is represented as being fixed in
the same manner as the plate shewn in Figures 8 and except that the nut fis
provided with an eye for the usual chain.
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. A step or stair-tread, landing, flooring or the like consisting of a perforated
plate and flanged blocks of elastic material (preferably of elliptical or circular
shape) passing through the perforations and projecting above the surface of the
plate to form the tread or wearing surface, the said blocks being adapted to be
placed in or removed from the said perforations, substantially as described and
illustrated in the accompanying drawings.
2. A carriage-step constructed substantially as described and illustrated in
Figures 8 and 9 of the accompanying drawings.
3. A coal-plate constructed substantially as described and illustrated in Figures 10
to 13 of the accompanying drawings.
