page_text: Sealed the 10th November 1865, and dated the 26th June 1865.
PROVISIONAL SPECIFICATION left by the said Thomas Lewis Jowett at
the Office of the Commissioners of Patents, with his Petition, on the
26th June 1865.
1, THOMAS LEWIS JOWETT, of Swansea, in the County of Glamorganshire,
Architect, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN BRICKS," to be as follows:-
The object of this Invention is to afford means for the better adherence of
plaster or cement with which the interior or exterior surface of brickwork is
often coated, and the improvements consist in forming bricks with dovetailed-
The
shaped grooves or indentations on one or more of their sides or faces.
grooves are made either parallel to any one of their sides, or at any convenient
angle thereto, or they may be made parallel to the said sides on one or more
faces, and angular on one or more of the others.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Lewis Jowett in the Great Seal Patent Office on the
23rd December 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, 1, THOMAS
LEWIS JOWETT, of Swansea, in the County of Glamorganshire, Architect, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of June, in the year of our Lord One
thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Thomas Lewis Jowett, Her special licence that 1, the said Thomas Lewis
Jowett, my executors, administrators, and assigns, or such others as 1, the
said Thomas Lewis Jowett, 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 " IMPROVд-
MENIS IN Baicks," upon the condition (amongst others) that I, the said
Thomas Lewis Jowett, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 1, the said Thomas Lewis Jowett, 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, reference being had to the accompanying Drawings, that is to
say:-
These improvements consist in the formation of bricks in such manner as
to ensure a more perfect attachment of plaster, cement, or other material
wherewith it is necessary or desirable they should be covered, or partially
covered, or fastened to; and in order to effect this the bricks are formed with
dovetailed-shaped grooves or indentations on one or more of their sides or
faces. The grooves may be made parallel to any one of their sides, or at any
convenient angle thereto, or they may be made parallel to the said sides on
one or more faces, and angular on one or more of the others. By the use of
bricks so formed the liability to the peeling or falling off of plaster or cement

page_text: is greatly diminished, if not wholly prevented, and greater facility is afforded
for the attachment of other materials, while the expense of their manufacture
is not increased.
In order that no misapprehension may exist, Drawings are attached hereto
showing the form and manner in which the said bricks are used.
Figs 1, 2, 3, and 4 are perspective views of the bricks showing the grooves;
Fig. 6, a section of a nine-inch wall, with common face on one side and lined
with plaster on the other; Fig. 7 is also a section of a nine-inch wall, faced
with cement on the exterior and lined with plaster on the interior; while
Fig. 5 shows the section of a four-and-a-half inch partition faced with plaster
on both sides.
In some of the illustrations referred to, for the sake of simplicity, one
groove only is shown in each brick, and indeed this is considered sufficient
under some circumstances, but for other purposes the grooves may be
increased in number and varied in direction.
Having now described and particularly set forth the nature of this
Invention, and the manner in which the same is or may be used or carried
into effect, I would observe in conclusion, that I do not confine myself to the
precise details or arrangements which I have described or referred to, as
variations may be made without deviating from the principles or main features
of this Invention; but what I consider to be novel and original, and therefore
claim as the Invention secured to me by the herein-before in part recited
Letters Patent, is the formation of bricks either of clay, cement, or other
suitable material capable of being moulded or shaped substantially as herein
described.
In witness whereof, I, the said Thomas Lewis Jowett, have hereunto
set my hand and seal, this Twenty-second day of December, in the
year of our Lord One thousand eight hundred and sixty-five.
THOS. LEWIS JOWETT. (L.S.).
