Year: 1856

page_text: LETTERS PATENT to John Taylor, of Spring Grove, Hounslow, in the
County of Middlesex, for the Invention of "AN IMPROVEMENT IN BUILDING
WALLS."
Sealed the 6th March 1857, and dated the 10th September 1856.
PROVISIONAL SPECIFICATION left by the said John Taylor at the Office
Petition, on the 10th
of the Commissioners of Patents, with his Petition, on
September 1856.
I, JOHN TAYLOR, of Spring Grove, Hounslow, in the County of Middlesex,
do hereby declare the nature of the Invention for "AN IMPROVEMENT IN
BUILDING WALLS," to be as follows:-
This Invention has for its object an improvement in building walls. For
this purpose face plates or slabs either of brick, earth, stone, or artificial stone,
or composition are used, each being made with a flange or projection on its
inner lower edge, which slabs or plates are similar to what have been made
and employed by me according to Inventions described in the Specifications of
former Patents granted to me. These facing plates or slabs are used in com-
bination with concrete in the following manner:-The slabs or facing plates
are used in pairs, so as to form blocks of concrete faced on the two surfaces; or,
what is preferred, several of the facing plates or slabs are arranged end to end
in two parallel lines, at a distance apart depending on the intended thickness
of the wall, the flanches being inwards. Concrete is to be poured into the
space between the parallel lines of facing slabs or plates, but
partially fill such space, and the concrete is to be allowed to set. The space is
then to be completely filled with concrete, the upper surface thereof being
struck off or made level with the upper edges of the facing slabs or plates.
only so as to

page_text: Other facing slabs or plates are then placed in a similar manner in parallel
lines on those previously mentioned, these slabs or plates by preference break-
ing joint with those below, and the spaces between these slabs or plates are
then to be filled, as above described, with concrete.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Taylor in the Great Seal Patent Office on the
10th March 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
TAYLOR, of Spring Grove, Hounslow, in the County of Middlesex, send

One thousand eight hundred and fifty-six, in the twentieth year of Iler reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
John Taylor, Her special licence that I, the said John Taylor, my executors,
administrators, and assigns, or such others as I, the said John Taylor, my
executors, administrators, and assigns, should at any time agree with, and
no others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "AN IMPROVEMENT IN BUILDING WALLS,"
upon the condition (amongst others) that I, the said John Taylor, my executors
or administrators, by an instrument in writing under my, or their, or one of
their hands and seals, should particularly describe and ascertain the nature of
the said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said John Taylor, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
This Invention has for its object an improvement in building walls. For
this purpose face plates or slabs either of brick, earth, stone, or artificial stone,
or composition are used, each being made with a flange or projection on its
inner lower edge, which slabs or plates are similar to what have been made

page_text: and employed by me according to Inventions described in the Specifications of
former Patents granted to me. These facing plates or slabs are used in com-
bination with concrete in the following manner: -The slabs or facing plates
are used in pairs, so as to form blocks of concrete faced on the two surfaces;
or, what is preferred, several of the facing plates or slabs are arranged end to
end in two parallel lines, at a distance apart depending on the intended thick-
ness of the wall, the flanches being iuwards. Concrete is to be poured into
the space between the parallel lines of facing slabs or plates, but only so as to
partially fill such space, and the concrete is to be allowed to set. The space
is then to be completely filled with concrete, the upper surface thereof being
struck off or made level with the upper edges of the facing slabs or plates.
Other facing slabs or plates are then placed in a similar manner in parallel
lines on those previously mentioned, these slabs or plates by preference break-
ing joint with those below, and the spaces between the slabs or plates are then
to be filled, as above described, with concrete.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
The Drawing represents sections and plans of blocks and wall constructed
according to my Invention, the facing slabs or plates having a flange or pro-
jection on the lower edge, and the concrete before described. In the Drawing,
Section 1, A, A, are the pair of slabs or facing plates; B is the concrete
partially filling up the space; C, Section 2, is the concrete completely filling
up the space. Plan 1 shows the slabs before being filled with concrete; Plan 2,
when filled with concrete; Plan 3, D, D, are the slabs placed apart in parallel
lines, filled in with concrete, as bofore described; Plan 4 is the course above it,
the joints of the facing slabs breaking joint with those below. Section 3 shows
three courses of slabs filled with concrete.
In witness whereof, I, the said John Taylor, have hereunto set my hand
and seal, this Ninth day of March, in the year of our Lord One
thousand eight hundred and fifty-seven.
