PROVISIONAL SPECIFICATION left by the said Henry Avins and
George Tarplee at the Office of the Commissioners of Patents,
with their Petition, on the 29th January 1853.
WE, HENRY AVINS, of Birmingham, in the County of Warwick,
Timber Merchant and Sawyer, and GEORGE TARPLEE, of Birmingham,
aforesaid, Clerk of Works, do hereby declare the nature of the said
Invention for "A NEW OR IMPROVED BRICK" to be as follows: -
Our Invention consists in making bricks hollow in the manner
represented in the Drawing. Fig. 1, represents a brick made according
to our Invention, the said brick being represented in longitudinal
section; and Fig. 2, represents a transverse section of the same; a, b,
is an opening in the brick, the said opening being vertical; that is
to say, extending from the top to the bottom face of the brick; the
said opening is divided by the partition c, so that at its lower part

page_text: the said opening is divided into two openings. The partition c,
may be omitted, or more partitions than one inay be used, the
essential feature in our Invention being making bricks with
hollows or openings situated vertically that is to say, extending
from the top face to the bottom face of the said bricks.
SPECIFICATION in pursuance of the conditions of the Letters
Patent, filed by the said Henry Avins and George Tarplec in
the Great Scal Patent Office on the 29th July 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, WE,
HENRY AVINS, of Birmingham, in the County of Warwick, Timber
Merchant and Sawyer, and GEORGE TARPLEE, of Birmingham afore-
said, Clerk of Works, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of January, in the
year of our Lord One thousand eight hundred and fifty-three, in the
sixteenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Henry Avins and George Tarplee,
Her special licence that we, the said Henry Avins and George
Tarplec, our executors, administrators, and assigns, or such others
as we, the said Henry Avins and George Tarplee, our 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 "A NEW OR IMPROVED BRICK," upon the condition (amongst others)

page_text: that we, the said Henry Avins and George Tarplee, by an instru-
ment in writing under our hands and seals, or under the hand
and seal of one of us, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Henry Avins and George
Tarplee, 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,
reference being had to the accompanying Drawing, and to the
figures and letters marked thereon (that is to say):
e,
Our Invention consists in making bricks hollow in the manner
herein-after described, and illustrated by the accompanying Drawing.
Figure 1, represents a plan of the lower face of the brick made
according to our Invention; and Figure 2, represents a plan of
the upper face of the same; Figure 3, represents a longitudinal
horizontal section of the said brick, the said section being taken
through the line a, Figure 1; Figure 4, represents a transverse vertical
section taken through the line b, Figure 1; and Figure 5, represents
a transverse vertical section taken through the line c, Figure 1; d,
is an opening or hollow in the brick, the said opening being ver-
tical, that is to say, extending from the top to the bottom face of
the said brick; the said opening d, e, is divided by the partition f
which said partition may either extend from the top to the bottom
of the brick, as represented, or the said division may not extend
beyond the line g, Figure 3. Each of the parts d, e, of the
opening is subdivided into two openings d', d, e, ell, as illustrated
in Figure 3, so that on one face of the brick there are four openings
d', d, e, e, Figures 2 and 3, and on the other face of the said
brick two openings d, e, or where the division f, Figure 3, does not
extend beyond the line g, Figure 3, only one opening. We some-
times omit the partition f, and we sometimes insert other partitions,
the essential feature in our Invention being making bricks with

page_text: hollows or openings situated vertically, that is to say, extending
from the tops to the bottoms of the said bricks. In using our
improved bricks we prefer laying the face represented in Figure 1,
downwards, so that the face, Figure 2, shall be at top for the
purpose of receiving the mortar. Our improved brick is much
lighter than the ordinary brick, and contains less clay; it con
sequently dries much quicker, and is less likely to crack in burning.
In constructing buildings our improved brick combines lightness
and strength and security against damp.
Having now described the nature of our said Invention, and the
manner in which the same is to be performed, we wish it to be
understood that we do not limit ourselves to the precise method of
carrying our Invention into effect herein described, as the same may
be varied without departing from the nature of our said Invention;
for example, the hollows or openings, instead of passing completely
through the bricks as described, may be made to pass nearly, but
not quite, through the same. But we claim as our Invention the
inaking of bricks with hollows or openings situated vertically, that
is to say, extending from the top to the bottom face of the same, as
herein described, and represented in the accompanying Drawing.
In witness whereof, we, the said Henry Avins and George
Tarplee, have hereunto set our hands and seals, this Twenty-
sixth day of July, in the year of our Lord One thousand
eight hundred and fifty-three.
Witness,
GEORGE SHAW.
