Year: 1875

page_text: LETTERS PATENT to James London Wood, of the Retreat, New
Southgate, Middlesex, for the Invention of "MAKING A NEW BLOCK OR
BRICK FOR BUILDING PURPOSES."
Sealed the 31st March 1876, and dated the 18th October 1875.
PROVISIONAL SPECIFICATION left by the said James London Wood
at the Office of the Commissioners of Patents, with his Petition,
on the 18th October 1875.
I, JAMES LONDON WOOD, of the Retreat, New Southgate, Middlesex,
do hereby declare the nature of the said Invention for "MAKING A
NEW BLOCK OR BRICK FOR BUILDING PURPOSES," to be as follows:-
:-
The block or brick will be composed of a mixture of either or any of
the following materials, (namely,) stone, lime, cement, breeze, shingle,
granite, marble, plaster, chalk, and clay, and moulded, cast, or worked
by hand, and of any size requisite for building purposes, the external
face of the block or brick will be bevelled on each edge to form a V joint
when fixed, and grooved with a hollow groove up the centre of sides

page_text: and ends as a provision for a proper and substantial bond when fixed.
After laying cach course the groove or hollow will be filled in with a
grouting of a mixture composed of cement or lime and sand, or any
other material required. The blocks or bricks will be laid on each
other without the grouting, so that they will take an equal bearing,
leaving no joint of mortar or any other substance between the blocks or
bricks when fixed.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
LONDON WOOD, of the Retreat, New Southgate, Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of October, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said James London Wood,
Her special license that I, the said James London Wood, my exc-
cutors administrators, and assigns, or such others as I, the said
James London Wood, 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 "MAKING A NEW BLOCK OR BRICK FOR
BUILDING PURPOSES," upon the condition (amongst others) that I, the said
James London Wood, my executors or administrators, by an instru-
ment 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.

page_text: NOW KNOW YE, that I, the said James London Wood, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, that is to say :-
The object of this Invention is to manufacture a block or brick
having a groove or hollow (shewn at d on the accompanying Drawing)
formed around its four sides, or such groove or hollow may be formed
around one, two, or three of its sides only, as occasion may require; such
groove or hollow is for bonding purposes. Into such grooves or hollows
when building I introduce grouting or any other suitable material, after
which I place another brick or block thereon when they firmly adhere
together. By this means I am enabled to construct any building,
ornamental or otherwise, without marring its appearance as is ordinarily
done by the seams of mortar between each course of bricks, and to
build with much greater rapidity than has hitherto been practicable.
Such improved blocks or bricks may be moulded either by hand or
machinery, and may be made to any suitable size, shape, and thickness,
and either with or without the bevel or V joint shewn at b in the
accompanying Drawing, according to the work for which the blocks or
bricks may be required. They can also be made with ornamental faces
by inserting tiling, glazed, or any enamelled material of such color and
design as may be desirable.
Any of the following materials may be employed in the manu-
facture thereof, that is to say :-Clay, lime, and sandstone, chalk, blue
lias, and other limes, Portland and other suitable cements, plaster, burnt
ballast, gravel, sand, shingle, breeze, glass, shells, marble, any kind of
metallic or minerals, or any other suitable material; and oil, tar, or any
other suitable liquids may be used for drying or mixing the same.
The accompanying Drawing represents one of my improved blocks or
bricks. a represents the face; represents the bevel on face; c, d, and
e, the top bed; d, channel groove or hollow sides, top, and bottom of
cach bed to receive grouting for bonding purposes.
Having thus described the nature of my said Invention and the
manner of carrying the same into effect, I would have it understood that
what I claim is,-
First. The formation of the groove or hollow on one or more sides of

page_text: the block or brick to any suitable depth and width for bonding purposes,
as heroin-before described.
Second. The formation of the V joint in such block or brick, as
herein-before described.
In witness whereof, I, the said James London Wood, have here-
unto set my hand and seal, this Eighteenth day of April, in
the year of our Lord One thousand eight hundred and seventy-
six.
