JAMES DAVY DENNY Newbridge, Ruabon N. Wales (Manager at Mr. J. C.
Edwards Encaustic Tile Works Ruabon N. Wales) I do hereby declare the nature
of my invention for BRICKS, FACED BRICKS AND ORNAMENTAL BRICKS
GLAZING OR OTHERWISE ALSO IN THE Box & PLATES FOR MAKING THE SAID
BRICKS to be as follows:-
FOR
The Bricks to be made out of Plastic Clay & Moist Ground Clay-also out of all
Plastic Clay and likewise of all Moist Ground Clay, as described in the Provisional
Specification.
The Box & Plates used for making the Bricks are fully explained in the
Provisional Specification-Four ornamental faces or four plain faces can be
put on a Brick by this process and of a good thickness.
Terra Cotta Brackets &c can be pressed by this process and will not require any
touching" up like those inade in plaster moulds.
BRICKS MADE FROM PLASTIC & MOIST GROUND CLAY,
Take a piece of Plastic Clay and put it in the Box as shown by transverse
section marked B on Drawing, then lower the top die gently down sufficient to
force the Plastic Clay as shown by transverse section marked B. then pull out
Plate C to whatever thickness you require for the face of the Bricks, also draw out
the "Plate Lid" and fill in the opening for the face with Moist Ground Clay as
shown by transverse section marked B, then push in the Plates C by aid of the
screw, also push in the lid, after which lower the top die down to its proper place,
then the Brick is made, see transverse section marked A on Drawing, by pushing
in the Plates C about a sixteenth of an inch in to the Box, the Brick may be
easily lifted out of the Box, by raising the bottom Plate. Bricks can be made
entirely of Plastic Clay by this process viz the centre of the Brick may be of Red
or Fire Clay (or any Plastic Clay) and faced with White Blue or Green Plastic
Clay.
Bricks can be made of entirely Moist Ground Clay, by keeping Plates (Blush
with the inside of the Box, then lower the top die down suflicient to make the

page_text: Clay firm, then draw out the Plates C to the thickness you require the face of the
Brick, 6 in with Clay of the color required, as shown by transverse section
marked B, then push in Plates C after which lower the top die down as required
the Brick is then inade.
Bricks by this process may be made of various sizes out of this Box, by pushing
in the Plates C to the size required, this may be done by slipping a piece or pieces
of different sizes on the Plates C as to the sizes required.
Four faces, plain or ornamental can be put on a Brick at once, and of any
patterns, by slipping the facing Plates on Plate C.
By this process a plain face you can get better and thicker than on the face of
Bricks that are made now, they only being dipped on the face with slip.
Terra Cotta Brackets &c may be made out of the Box by having ornamental
facing Plates slipped on Plates C.

Improvement in Making Bricks, Faced Bricks, and Ornamental
Bricks for Glazing or otherwise, also in the Box and Plates
for Making the said Bricks.
JAMES DAVY DENNY Newbridge, Ruabon N. Wales, Manager at Mr. J. C.
Edwards' Encaustic Tile Works Ruabon N. Wales) I do hereby declare the
nature of my invention for IMPROVEMENT IN MAKING BRICKS, FACED BRICKS
& ORNAMENTAL BRICKS FOR GLAZING OR OTHERWISE, ALSO IN THE BOX AND
PLATES FOR MAKING THE SAID BRICKS, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
The Bricks to be made out of Plastic Clay and Moist Ground Clay, also out
of all Plastic Clay, and likewise of all Moist Clay Ground, as described in the
Specification.
The Box and Plates to be used for making the Bricks are fully explained in the
Specification Four ornamental faces, or four plain faces can be put on a Brick by
this process, and of a good thickness.

touching" up like those made in plaster moulds.

page_text: BRICKS MADE FROM PLASTIC & MOIST GROUND CLAYS.
Take a piece of Plastic Clay and put it in the Box as shown by transverse
section marked B. on Drawing then lower the top die gently down sufficient to
force the Plastic Clay (as shown by transverse section marked B) then pull out
Plate (or side die) C to whatever thickness you require for the face of the Brick,
also draw out the Plate Lid, and fill in the opening for the face of the Brick with
Moist ground Clay, as shown by transverse section marked B on Drawing, then
push in the Plates (or side dies) C by aid of the screws, and at the same time
push in the lid, after which lower the top die down to its proper place, the Brick
is then made, see transverse section marked A on Drawing, by pushing in the
Plates (or side dies) C about a sixteenth of an inch in the Box, the Brick may
be easily lifted out of the Box, by raising the bottom Plate. The Brick is then
allowed to dry, after which it is dipped in a glaze and fired in the ordinary way.
BRICKS MADE ENTIRELY OF PLASTIC CLAY.
Roll out a piece of facing Clay, of the color you want say 3 feet wide by
1 foot 6 ins long and of an inch in thickness, then cut it, with wire, in pieces the
size of the faces or ends of the Bricks as may be required, then take a piece of
body Clay of any color, and face it with the rolled facing Clay, after which put it
in the Box, lower the top die down to the proper level in the Box, as shown by
transverse section marked A on Drawing, then push in all the Plates (or side &
end dies) C, the Brick is then made, raise the bottom plate, and take the Brick out
of the Box. Dry it and dip it in the glaze, it is then ready for firing.
BRICKS MADE OF MOIST GROUND CLAY.
Push the Plates (or side & end dies) C flush with the inside of the Box, then fill
the Box with Moist Ground Clay (roughly ground if required) after which lower
the top die down sufficient to make the Clay firm in the Box, then pull out the
Plates (or side and end dies C to the thickness for which you require to face
the Brick then fill in the thicknesses of the faces and ends of the Bricks (as the
case may be), with the facing Moist ground Clay, then push in the Plates C (or
end & side dies) by aid of the screws, then lower the top die down with a good
force, the Brick will be then made, after which raise the bottom Plate, and take
the Brick out of the Box-dry it, dippet in the glaze and fire it in the ordinary
way.
Briks by this process may be made of various sizes out of the same Box, by
bevelling the Plates C (or side and end dies) on the ends of the Plates C. and then
pushing the Plates C farther in the Box, as may be required.
Four faces, plain or ornamental, can be put on Bricks at the same time, and of
any patterns, still retaining the Plates (or side and end dies) C by slipping on the
facing Plates of different patterns on the Plates (or side & end dies) C as shown by.
full size diagram on Drawing.
By this process, plain or ornamental faces can be put on Bricks, of a good
thickness say "to of an inch in thickness, (thicker if required) so different to
the Bricks that are now made they are pressed in the ordinary way and then
taken out of the Box, allowed to dry, afterwards dipped in slip which when dry is
only of the thickness of a wafer, again allowed to dry, then dipped in glaze ready
for firing.
The slip on the Bricks on being exposed to the air invariably chip off, or shell
off, causing the body of the Brick (which in most cases is of a different color
to the slip) to be visible. Bricks made by my process will not shell off, will
"stand" the weather, and sea water, should a portion of the glaze be chipped off
by accident, you do not see the body of the Brick, but the color of the face of the
Brick, which in most cases will be of the same tint as the glaze or enamel.

page_text: Terra-Cotta Brackets, Cornices, Mouldings, Coping &c can be made by this
process, Cornices, Mouldings & Coping may be made in ordinary lengths say
2 feet lengths (in fact in any size that will burn straight in the firing) by the aid
of steam power attached to the Plates (or side & end dies) C.
Fenders may also be made by this process as shown by Fig. No 1 on Drawing,
by having an ornamental top die, in addition to Plates C. the angle pieces would
require the Plates C to be bevelled at the side of each Plate.
The "Arris" can be taken off the Brick at the same time it is being made,
by having a projection on the facing Plates, as shown by full size diagram on
Drawing.
I claim as my Invention as follows,
Uniting Plastic Clay with ground moist Dust Clay in any colors of an inch
thick, or more as the case may be, on the face or faces of a Brick, or Cornices,
Paterns &c in Terra Cotta, the body of the Bricks &c being made of and Plastic
rough Clay, and the faces of ground moist Dust Clay.
Also Plastic Clays may be used entirely, viz for the body and face of what is
required.
I also claim as my Invention the introduction of the side dies marked C (on
Drawing) with the lid, and the facing, plain, ornamental and arrising Plates, the
side dies when screwed in and the top die lowered gives the Bricks &c a double
pressure.
