AN IMPROVED PAVING FOR ROADS, WAYS, AND OTHER PLACES."
Year: 1877

page_text: LETTERS PATENT to John William Dennison, of 33, King Street, Cheapside,
in the City of London, Architect, for the Invention of "AN IMPROVED PAVING
FOR ROADS, WAYS, AND OTHER PLACES."
ed the 21st December 1877, and dated the 1st September 1877.
PROVISIONAL SPECIFICATION left by the said John William Dennison at
the Office of the Commissioners of Patents on the 1st September 1877.
JOHN WILLIAM DENNISON, of 33, King Street, Cheapside, in the City of London,
Architect. "AN IMPROVED PAVING FOR ROADS, WAYS, AND OTHER PLACES."
This Invention relates to improvements in the manner of laying and securing
granite and other block paving with a view to increasing its solidity and imperme
ability, and of lessening the noise and other disadvantages of paved roads.
In carrying out my Invention, on the ordinary concrete or other suitable bed I
spread a layer of felt or other non-conductor of sound, and upon this place the
blocks; and in lieu of the ordinary method of grouting I fill in the joints partly
with sand, or tow, or asphalte, or other non-conductor of sound, say to within an
inch of the top; I then fill up the remaining part of the joints with molten lead.
The blocks are advantageously considerably less in depth than those usually
employed; and where very small blocks are used a number of them may be
previously secured together, as above described, in a frame, and the paving is then
laid in large slabs.
I do not restrict myself to any particular description of paving, or size or form of
block or joint, as my Invention consits in the novelty of running in the joints of
paving with lead, so that each block may be isolated and firmly embedded in and
upon an efficient non-conductor of sound, and so that the isolating material is
protected from weather and other influences in a practical manner, and as hitherto
unapplied.

JOHN WILLIAM DENNISON, of 33, King Street, Cheapside, in the City of London,
Architect. "AN IMPROVED PAVING FOR ROADS, WAYS, AND OTHER PLACES."
This Invention relates to improvements in the manner of laying and securing
gracite and other block paving with a view to increasing its solidity and imperme-
ability, and of lessening the noise and other disadvantages of paved roads.
In carrying out my Invention, on the ordinary concrete or other suitable bed I
spread a layer of felt or other non-conductor of sound, and upon this I place the
blocks; and in lieu of the ordinary method of grouting I fill in the joints partly
with sand, or tow, or asphalte, or other non-conductor of sound; I then fill or nearly
fill up the remaining part of the joints with molten lead.
The blocks are advantageously considerably less in depth than those usually
employed; and where very small blocks are used a number of them may be
previously secured together, as above described, in a frame, and the paving is then
laid in large slabs.
I do not restrict myself to any particular description of paving, or size or form of
block or joint, as my Invention consists in the novelty of running in the joints of
paving partly with lead, so that the blocks may be isolated from each other, as
previously described, and firmly imbedded in and upon an efficient non-conductor of
sound, and so that the isolating material is protected from weather and other
influences in a practical manner, and as hitherto unapplied.
Having thus described the nature of my improvements, and the manner of
performing or carrying the same into practice, I would remark that I am aware that
it has before been proposed to combine blocks of granite or other stone together by
a certain alloy or compound of metals into slabs for paving roads, I therefore make
no claim broadly thereto; but what I claim is, the improved method of paving
roads, ways, and other places with granite or other paving blocks isolated from each
other, and between which and the ordinary concrete or other suitable bed a layer of
felt, sand, or other non-conductor of sound is placed, the interstices between the
blocks being partly filled in with lead, substantially as herein-before described.
In witness whereof, I, the said John William Dennison, have hereunto set my
hand and seal, this Twenty-sixth day of February, in the year of our Lord
One thousand eight hundred and seventy-eight.
