PROVISIONAL SPECIFICATION.
An Improved Method of and Means for the Construction of
Public Roadways.
I, DONALD NICOLL of 12 Buckingham Street, Charing Cross in the County of
London, Civil Engineer do hereby declare the nature of this invention to be as
follows:-
I prepare by any suitable means on the site of the contemplated roadway a firm
surface with a fall from its centre to each of its sides on that surface I bend water-
proof slabs prepared by the use of substances described in the Specification of a patent
granted to me 28th September 1888 No. 13,971 but under certain conditions I may
add to the compound therein described any or all of the ingredients set forth in a
Specification of a patent granted to me on the 31st August 1867 No. 2480, and any
or all of the ingredients described in a patent granted to me in the year preceding
viz. 1866, dated 15th February No. 480, the said waterproof slabs are formed of any
suitable dimension or thickness and prepared at the edges so that they lap over for
junction which operation is effected by a heated iron being passed over the over-
lapping parts. I then take blocks of granite or any other suitable substance capable
of receiving the percussion and wear and tear of vehicular and other traffic these
blocks I shape so as to exhibit surfaces which by preference do not exceed 3 inches
square and round these blocks which may be of any suitable depth I wrap slips of the
waterproof substances herein before mentioned, the thickness of these wrappings
I prefer should not exceed a quarter of an inch these blocks when much worn on the
surface may be raised and the lower ends brought to the top they are laid by
preference diagonally over the curved slabs or substratum hereinbefore described the
blocks are made to adhere together by heat or flame being applied at the points
of junction and by pressure produced by leverage from apparatus adapted for that
purpose.

An Improved Method of and Means for the Construction of
Public Roadways.
I, DONALD NICOLL of 12 Buckingham Street, Charing Cross in the County of
London, Civil 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 :-
I prepare by any suitable means on the site of the contemplated roadway a firm
surface with a fall from its centre to each of its sides on that surface I bend water-
proof slabs prepared by the use of substances described in the Specification of a
patent granted to me 28th Septr. 1888 No. 13971 but under certain conditions
may add to the compound therein described any or all of the ingredients set forth
in a Specification of a patent granted to me on the 31st August 1867 No. 2480 and
any or all of the ingredients described in a patent granted to me in the year preceding
viz. 1866 dated 15th February No. 480 the said waterproof slabs are formed of any
suitable dimension or thickness and prepared at the edges so that they lap over for
junction which operation is effected by a heated iron being passed over the over-
lapping parts. I then take blocks of granite or any other suitable substance capable
of resisting the percussion and wear and tear of vehicular and other traffic these
blocks I shape so as to exhibit surfaces which by preference do not exceed 3 inches

page_text: square and round these blocks which may be of any suitable depth I wrap slips of
the waterproof substance herein before mentioned the thickness of these wrappings
I prefer should not exceed a quarter of an inch these blocks when much worn on the
surface may be raised and the lower ends brought to the top they are laid by preference
diagonally over the curved slabs or substratum herein before described the blocks are
made to adhere together by heat or flame being applied at the points of junction and
by pressure produced by leverage from apparatus adapted for the purpose.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed, I state that in respect to road-
ways for foot passengers only I do not restrict myself to the size of the blocks I may
use or to the distances they may be kept asunder by intervening substances neither
do I restrict myself to a flat surface being given to substratum slabs as I may by
compression or otherwise make recesses therein to receive tubes cables or wires for
the service of electric conductors but I declare that what I claim is
The use of blocks adapted substantially for paving purposes which except on their
exposed surfaces I swathe by wrappings of vegetable fibre in combination with
bituminous substances and which wrappings are made to adhere together by the
leverage of a clamping machine the said blocks and wrappings being in situ and
I use such an amount of pressure as may fill up any inequality of the covered lateral
surfaces and I thus prevent water penetrating to the foundations of the completed
roadway.
