CERTAIN NEW METHODS OF CONSTRUCTING AND CONNECTING EARTHEN BUILDING MATERIALS
Year: 1813

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPHI
HAMILTON, of the City of Dublin, Gentleman, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of our United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twentieth day of
February, in the fifty-third year of His reign, give and grant unto me, the
said Joseph Hamilton, my exors, adiiors, and assigns, Iis especial licence, full
power, sole privilege and authority, that I, the said Joseph Hamilton, my exors,
adiiors, and assigns, should and lawfully might, during the term of years
therein mentioned, make, use, exercise, and vend, within England, Wales, and
the Town of Berwick-upon-Tweed, my Invention of "CERTAIN NEW METHODS
OF CONSTRUCTING AND CONNECTING EARTHEN BUILDING MATERIALS;" in which said
Letters Patent there is contained a proviso that if the said Joseph Hamilton
shall not particularly describe and ascertain the nature of my said Invention,
and in what manner the same is to be performed, by an instrument in
writing under his hand and seal, and cause the same to be enrolled in His
Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said Letters Patent, that then the said
Letters Patent, and all liberties and advantages whatsoever thereby granted
shall utterly cease, determine, and become void, as in and by the same
(relation being thereunto had) may more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso; I, the said
Joseph Hamilton, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are particularly described in
manner following, that is to say :-
Firstly, I do not only make, fabricate, or construct the bricks, or masses,
or lumps, or separate pieces of the said earthen building materials of the
ingredients commonly used for such purposes, and severally of the forms,
figures, sizes, and dimensions most suitable to be used or applied in and for
building walls, pavements, floors, arches, and other structures, but I do like-
wise make perforations in and thro' the same vertically, as to the position in
which the same are or may be required or intended to be laid or otherwise.
I do make the said perforations in lateral or oblique directions; but in all
cases so that the said perforations in each of the said bricks, or masses, or
lumps, or separate pieces shall or may correspond with or be opposite to
similar perforations in such other of the said bricks, masses, lumps, or separate
pieces, as shall or may be contiguous thereto when duly disposed in the build-
ings or structures intended to be made. And farther, I do make or fabricate
certain pins, bars, bolts, or nails, or pieces of the like kind or description of
baked earth, or metal, or wood, or other fit material, either round or square,
or of such other figures as may be best adapted to enter into and become
fixed in the said perforations correspondent with or opposite each other, so as
to lock or connect or firmly tie or unite the said bricks, masses, lumps, or
pieces together with or without the use of mortar, cement, putty, or other
similar binding or filling material.
And, secondly, I do connect the said earthen building materials by putting
the same together in the usual manner of laying or building in bond or other-
wise; and I do insert in the corresponding perforations of the contiguous
bricks, masses, lumps, or pieces aforesaid, such several pins, bars, bolts, nails,
or pieces before mentioned, as shall lock, connect, tie, or unite the same toge-
ther, and in so doing I do in preference make use of mortar, cement, putty, or
other similar binding or filling materials, altho' the said connection
may
be
made without the use of such or the said last-mentioned articles or otherwise;
I do connect the said earthen building materials by putting between the said
materials, or the parts thereof, some of the vitrifiable substances such as are
known to be capable of being readily fused or fluxed by heat into the state of
glass; and I do from time to time, as the building may be carried on, make
the several parts thereof in succession red hot, by means of temporary inclo-
sures or furnaces surrounding or inclosing such parts, and containing fuel in
combustion, from which the requisite heat may and shall be communicated to

page_text: the building, and into and thro' flues, if thought needful to be made in the
same, and by that means may and shall vitrify the said substances and bind
or unite the said earthen building materials together.
In witness whereof, I, the said Joseph Hamilton, have hereunto set my
band and seal, the Sixteenth day of August in the year of our Lord.
AND BE IT REMEMBERED, that on the Sixteenth day of August, in the
year of our Lord 1813, the aforesaid Joseph Hamilton came before our said
Lord the King in His Chancery, and acknowledged the Specification afore-
said, and all and every thing therein contained and specified, in form above
written. And also the Specification aforesaid was stampt according to the
tenor of the Statute made for that purpose.
Inrolled the Nineteenth day of August, in the year of our Lord One
thousand eight hundred and thirteen.
