PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Pavement, Floor Coverings, and
the like of Rubber or Rubber Compounds.
I, JOHN COCKBURN, Assistant Manager to the North British Rubber Company
(Limited), Castle Mills, Edinburgh, do hereby declare the nature of this invention
to be as follows:-
This Invention relates to the manufacture of pavement and floor coverings for
lobbies, door entrances, halls and like situations of rubber or rubber compounds, and
it consists in forming therein coloured patterns or designs to produce the appearance
of tiles or mosaic work or of ordinary floor cloth or carpeting the said patterns or
designs being however, unaffected by wear of the surface.
In carrying out the invention I employ sheets of rubber or rubber compounds
which are partially vulcanised in order to permit facility of cutting or perforating
them. A sheet or sheets constituting the ground work (which may be of any
colour) is perforated or cut to produce the outline of any desired pattern or design
and from sheets of coloured rubber or rubber compounds pieces are cut to fill up
the interstices in the ground work. The cut edges of the coloured filling up pieces
are coated with suitable cementing material so that when fitted in position they
adhere to the corresponding edges of the groundwork sheets, and the variegated
sheets so produced are subsequently vulcanised. The sheets are then ready for laying
as floor coverings or paving but I prefer, more especially in cases where considerable
thickness is required, to cement the variegated sheet, either prior to or after filling in
the coloured pieces to a plain backing sheet of partially vulcanised rubber and sub-
sequently vulcanise the composite sheet thus formed.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Pavement, Floor Coverings, and
the like of Rubber or Rubber Compounds.
I, JOHN COCKBURN, Assistant Manager to the North British Rubber Company
(Limited) Castle Mills, Edinburgh 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 the manufacture of pavement and floor coverings for
lobbies, doors entrance halls and like situations of rubber or rubber compounds or
substitutes and it consists in forming therein coloured patterns or designs to produce
the appearance of tile or mosaic work or of ordinary floor cloth or carpeting the
said patterns or designs being however unaffected by wear of the surface like painted
designs.
In carrying out the Invention I employ two layers of the materials an under one
of a uniform colour and an upper one of variegated colour wherewith to bring out the
intended design. Both layers are partially vulcanized and the under one may be a
piece of canvas or sheeting coated with rubber or rubber compound or substitute.
The upper layer may be formed either wholly or partially in two ways, firstly by a
sheet of the same size as the under layer which sheet having been partially vulcanized
is perforated with openings to be filled with pieces of coloured material to bring out
the intended design. This may be called inlaying the coloured pieces of material and
Price 6d 1

page_text: is convenient for forming the borders and centre of such a design as shown in the
accompanying illustration; secondly by laying the coloured pieces of the upper layer
side by side on to the under layer which is convenient for formning the design between
the borders and centre piece of said illustration and may be called onlaying the
coloured pieces of the material to the under layer. The materials are as stated
partially vulcanized for facility and accuracy of cutting so that the design may be
finished with the needful artistic accuracy a result unattainable with raw or
unvulcanized materials combined to form a sheet. It is desirable and convenient to
apply a thin brush coating of india rubber cement (or solution of india rubber and
sulphur well known to rubber manufacturers) to the under surfaces of the materials
forming the upper layer and to the edges of the pieces composing the same so that
more perfect adhesion may be got between these pieces and between the upper and
under layers when heated to accomplish the full or final vulcanization.
In the accompanying drawing Figure 1 is a plan and Figure 2 a cross section
showing an example of a sheet or piece of paving or floor covering produced in the
manner herein before described. C is the under layer. The ornamentation in the
borders A and centre is produced by inlaying and the design in the middle by
onlaying the pieces of coloured materials such as B, 61, 62, 63, 64, and the black thick
lines forming the divisions by which the squares are brought out.
Having now particularly described and ascertained the nature of the said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is: :-
The manufacture of pavement floor coverings and the like of rubber or rubber
compounds or substitutes in the improved manner hereinbefore described.
