page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRIEDRICH
GESSWEIN, of Cannstadt, in the Kingdom of Wurtemburg, in Germany, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of
Great Britain and Ireland, bearing date at Westminster, the Sixth day of
July, One thousand eight hundred and fifty-two, in the sixteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Friedrich Gesswein, my exors, admors, and assigns, Her especial
licence, full power, sole privilege and authority, that I, the said Friedrich
Gesswein, my exors, admors, and assigns, or such others as I, the said
Friedrich Gesswein, my exors, adñors, or assigns, should at any time agree
with, and no others, from time to time and at all times during the terin of
fourteen years therein expressed, should and lawfully might make, use, exercise,
and vend, within England, Wales, and the Town of Berwick-upon-Tweed, and
in the Islands of Jersey, Guernsey, Alderney, Sark, and Man, and also in all
Her said Majesty's Colonies and Plantations abroad, my Invention of "A
METHOD OF PREPARING FOR BAKING AND BURNING MASSES OF CLAY OF ANY GIVEN
FORM AND SIZE, AND BAKING AND BURNING THE SAME WHEN SO PREPARED AS
THOROUGHLY AND COMPLETELY AS A COMMON BRICK CAN NOW BE BAKED OR BURNT;"
in which said Letters Patent is contained a proviso that I, the said Friedrich
Gesswein, shall cause a particular description of the nature of my said In-

page_text: vention, and in what manner the same is to be performed, by an instrument
in writing under my hand and seal, to be enrolled in Her Majesty's High
Court of Chancery within six calendar months next and immediately after
the date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Friedrich Gesswein, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and ascer-
tained in and by the following statement thereof, reference being had to the
Drawings hereunto annexed, and to the figures and letters marked thereon,
that is to say:-
My Invention consists of a mode of preparing clay when in moulds, in
order that the masses may be caused to fill the moulds with exactness, and at
the same time render the moulded masses more suitable for burning, by
reason of there being numerous perforations made therein. And in order
that my Invention may be most fully understood and readily carried into
effect, I will proceed to describe the means pursued by me.
DESCRIPTION OF THE DRAWING.
Figure 1 shows a side view, Fig. 2 an end view, and Figure 3 is a longi-
tudinal section of a moulded mass or block, there being longitudinal per-
forations through the same. In making such a block or mass I employ a
mould with perforated ends, into which mould is placed a quantity of clay to
fill it, the cover is then to be put on to the mould, and the parts thereof all
secured; the series of rods with pointed ends are then to be forced through from
one end to the other of the mould, and through the clay therein, by which the
clay will be forced or driven in all directions, and by which the mould will be
more exactly filled in all parts. The rods are then withdrawn, and the parts of
the mould are to be removed. I would state, that according to the character
of the surfaces of the moulded blocks or masses, so will be the nature of the
moulds, and the manner of putting together of the parts, as will readily
be understood by a workman. To the constructing of such moulds I make
no claim except the constructing them with perforations suitable for the
passage of rods, and the employment of such rods for the purpose of causing
the clay shut or enclosed in such moulds to be forced in various directions by
the passage of the rods into or through the same, and by which the clay will
be caused to enter and fill all the ornamental as well as other parts very
intimately. The blocks or moulded masses will also dry and keep their form
better than when light masses are moulded solid, and they will also burn moro

page_text: completely than solid masses. The other Figures of the Drawing shew
various forms of blocks moulded in like manner to what has been above
described in respect to Figures 1, 2, and 3, the moulds however employed for
such blocks being different in form and pattern, but similar in respect to being
constructed suitable for the passage of perforating rods through the moulds,
and through the clay therein after the moulds have been shut or closed.
I would remark that in like manner may other forms of blocks than those
shewn be made in suitable moulds constructed in such manner as to admit
of the passage of perforating rods, as above explained.
I would further remark, that bricks, blocks, tiles, and other articles have
been before made with numerous perforations through them, but such bricks,
blocks, and tiles have been produced by forcing clay through orifices provided
with suitable cores. I do not therefore claim the making of bricks, blocks, or
tiles with numerous perforations therein when produced by such means; but
what I claim is the mode of making perforations in blocks or masses of clay
whilst in suitable moulds, as herein explained.
In witness whereof, I, the said Friedrich Gesswein, have hereunto set my
hand and seal, this Thirteenth day of December, in the year of our
Lord One thousand eight hundred and fifty-two.
