on a kiln to dry, then ground into powder or dust, damped on a plaster of Paris
bed, or otherwise, again sieved through a wire sieve of the mesh required, ready
for use.
Hereafter the ground moist clay will be called "dust." After you have placed the
wire cut Brick in the box as shown by Fig. No. 1, take some of the "dust" of the
color required, and fill in the space from L to L (on Fig. No. 1) with it, then with a
straightedge strike off the "dust" so that it shall be level with the top of the box,
as shown on Fig. No. 2, then take plate G and put it on the opening on the top of
the box, press it down until the plate finds its level on the box, by so doing the
"dust 25
is pressed slightly, except in the open portion of the plate as shown by
Fig. No. 3, then take dust" of another color and fill in the opening from M to M.
Strike of the dust with a straightedge, leaving the dust level with the face of the
plate, as shown by Fig. 4. Take plate H and put it on the top of plate G. Then
tap or gently knock it, down until it is level with the top of plate Ġ as shown on
Fig. No. 5 afterwards lift off the two plates, by the aid of the handles at each end ;
and, at one operation, the Brick is then ready to be pressed see Fig. No. 6. (The
plate J on Fig. No. 1. which is "slipped" by a dovetail on the face of the top die or
plunger, as shown on Fig. No. 7. has a rim or projection on its face, corresponding
with the opening in plate G, thus preventing the several dusts from getting mixed.)
Lower the top die or plunger down and the Brick is made.

Fig. No. S. shews the face of plate J with the ornament inside the rim or projection.
Ornamental Tiles, terra cotta &c. can be made in like manner.

JAMES DAVY DENNY, Meadow Cottage Llangollen, N. Wales, Manager at the
Ruabon Brick and Terra Cotta Company Limited, Ruabon, N. Wales do hereby declare
the nature of this invention and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:-
For facing Bricks, Tiles, Terra Cotta &c. the body of the Bricks &c. to be of plastic
clay and then faced with ground moist clays in various patterns, (by the aid of the
plates) and in different colors.
"
The Bricks, Tiles, Terra Cotta &c. after being faced with the ground moist clays, to
be dried white hard then dipped in water, afterwards dipped in a white frit glaze,
or enamel, as may be required, then burnt in a "muffle
or glazed kiln.
The Bricks, Tiles, Terra Cotta &c. after being faced, may be dried, and then burnt,
not glazed, for external work.

Fig. No. 1 shews a wire cut Brick of plastic clay in a stiff state, put in the box,
ready to receive the facing, viz. the ground moist clay. The moist ground clay is
composed of several clays, (as may be required) mixed and blunged together into a
slip state, then stained as to color wanted, it is afterwards lawned, through a fine
copper sieve, and then put on a kiln to dry, then ground into, powder, or dust, after-
wards damp it on a plaster of Paris bed or otherwise, again sieve it through a wire
sieve of the "mesh" required, ready for use.
Hereafter the ground moist clay will be called "dust."
After you have placed the wire cut Brick in the box, as shown by Fig. No. 1, take
some of the dust of the color required, and fill in the space from L to L (on Fig. No. 1)
with it, then with a straightedge, strike off the "dust" so that it shall be level with
the top of the box, as shown on Fig. No. 2; then take plate G and put it on the
opening on the top of the box, press it down until the plate finds it level on the box,
by so doing the dust is pressed slightly, except in the open portion of the plate, as
shown by Fig. No. 3, then take dust of another color and fill in the opening
from M to M, strike off the "dust" with a straightedge, leaving the "dust" level
with the face of the plate, as shown by Fig. No. 4, take plate H and put it on the top
of plate G, then tap, or gently knock it down until it is level with the top of plate G,
as shown on Fig. No. 5, afterwards lift off the two plates, by the aid of the handles,
at each end, and at one operation, the brick is then ready to be pressed,
see Fig. No. 6. (The plate J on Fig. No. 1, which is "slipped" by a dovetail on the
face of the top die or plunger, as shown on Fig. No. 7, has a rim or projection on its
face, corresponding with the opening in plate &, thus preventing the several "dusts"
from getting mixed) Lower the top die or plunger down and the Brick is made..
Fig. No. 8 shews the face of plate J with the ornament inside the rim or projection.
Ornamental Tiles, Terra Cotta &c. can be made in like manner.
Bricks &c. can be made; with only the ground moist clay being used for the
ornamental portions, for instance say for a Brick, cut a piece of clay the size required
to fill the box, to within 1 of an inch of the face of the box, put it in the box, then
put on the box the 1st plate, after doing so, fill in the openings of the plate, with
ground moist clay, colors as may be required then put on 1st plate, the 2nd plate,
just tap, or knock, this plate, so as to press the ground moist clays to the face of the
piece of clay, afterwards take off the plates, it is then ready for the top die (with the
plate with the projections upon it, to keep the ground moist clay from mixing with
the face of the piece of clay) to be lowered down to make the Brick.
