PROVISIONAL SPECIFICATION.
Improvements in Sea or River Walls for Piers, Harbours, Quays,
Groynes, or other and similar Structures.
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 take concrete composed of any water repelling material and while in a plastic
condition I mould it into slabs or blocks by preference of oblong or square shapes
and of large dimensions I prefer to form these slabs or blocks to correspond with
others described in my Patent No. 14,733 dated 18th Septr. 1889 except that at
parts requiring to be very strong I increase the tenon and mortise arrangements
described in the said Patent and I also perforate the said slabs or blocks so as to
admit of the passage of an Iron Column.
The bottom slab or block I prefer to describe as the base slab or block as it would
be made usually of larger dimensions than other slabs or blocks forming the super-
structure. To the Iron Column I attach a footing or shoe with an iron projection
or socket at the points of junction with corresponding and joining base slabs or blocks.
I then pass the Iron Column through the perforation in the base slab or block from
which it extends sufficiently high to appear above the surface of the entire structure
thus forming a stanchion for mooring vessels or for other purposes the Sea or River
Wall for preventing encroachments would be completed by the ordinary slabs or
blocks passing over the Iron Column by means of the perforations described or the
slabs or blocks may be cemented together but for the erection of Piers Harbours or
Quays I use a double line of these Walls running parallel to each other and so
extending into the Sea or River as the case may be I then temporarily face the
entrance to the passage formed between the Walls and I fill the space with any cheap
form of concrete which as it is poured in drives out superabundant water and by
oozing through the fissures of the joints of the Walls the same are stopped and made
watertight and as the filling in concrete consolidates a tramway may be placed
thereon to convey materials for the extension of the work into deep water.
Dated this Sixteenth day of November 1889.

Improvements in Sea or River Walls for Piers, Harbours, Quays,
Groynes, or other and similar Structures.
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 take concrete composed of any water repelling material and while in a plastic
condition I mould it into slabs or blocks by preference of oblong or square shapes and
of large dimensions I prefer to form these slabs or blocks to correspond with others
described in my Patent No. 14733 dated 18th Septr. 1889 except that at parts
requiring to be very strong I increase the tenon and mortise arrangements described
in the said Patent and I also perforate the said slabs or blocks so as to admit of the
passage of an Iron or other metal Column. The bottom slab or block I prefer to
describe as the base slab or block as it would be made usually of larger dimensions
than other slabs or blocks forming the superstructure. To the Iron or other metal
Price A7

page_text: Column I attach a footing or shoe with an iron or other metal projection or socket at
the points of junction with corresponding and joining base slabs or blocks. I then
pass the Iron or other metal Column through the perforation in the base slab or block
from which it extends sufficiently high through the other blocks to appear above the
surface of the entire structure thus forming a stanchion for mooring vessels or for
other purposes. The Sea or River Wall for preventing encroachments would be
completed by the ordinary slabs or blocks passing over the Iron or other metal
Column by means of the perforations described or the slabs or blocks may be cemented
together but for the erection of Piers Harbours or Quays I use a double line of these
Walls running parallel to each other and so extending into the Sea or River as the
case may be I then temporarily face the entrance to the passage formed between the
Walls and I fill the space with any cheap form of concrete which as it is poured in
drives out superabundant water and by oozing through the fissures of the joints of
the Walls the same are stopped and made watertight and as the filling in concrete
consolidates a tramway may be placed thereon to convey materials for the extension
of the work into deep water.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed 1 state that when the structures have
to resist great pressure or force I do not restrict myself to the use of one penetrating
Iron or other metal Column but may employ an additional Column to pass through
the several slabs or blocks and for their shoes or connexions to be made solid so that
the Columns thus joined may more securely bring adjoining slabs or blocks firmly
together I declare that what I claim is
Substantially the use of tiers of slabs composed of any water repelling material
capable of being moulded into the required form while in a plastic condition and of
being perforated by an Iron or other metal Column or Columns which connect or
bracket together adjoining slabs or blocks in situ and thus to prevent the shifting
of the said slabs or blocks from the tenon and mortise formation provided for the
completion of the structure.
