WILLIAM JOHNSTONE JEFFREY Tile Traveller Spring Bank Madeley,
Shropshire JOHN GEORGE MOWBRAY JEFFREY Tile Designer and Artist
54 Park Road, Burslem, Staffordshire 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:-
The aforesaid backs to be made with one or more undercuts or incisions, at acute
angles, placed at intervals; or in lines, curved, diagonal, triangular or parallel as
shown in section drawing marked A.
The aforesaid undercuts or incisions at acute angles to be made from a block,
plate or die constructed in one or more pieces having projections like teeth, pointed
rounded, or angular as may be deemed advisable, to form undercuts or incisions as
heretofore described, and shown in section drawing marked B.
The aforesaid tiles, bricks or briquettes made from clay, or other suitable
materials, in a dust, plastic or liquid state would be made in dies or boxes by
pressure obtained in an ordinary tile or brick press or the like. The die would be
made in three parts the middle part, or box being a fixture, the bottom die, block
or plate to be as shown in section drawing marked B working up or down the inside
aforesaid middle part or box.
The clay or other materials in the states as before described being placed in the
middle part, or box of die would rest upon the bottom die, block or plate as shown
in section drawing marked B.
The upper or top, being the third portion of complete die, would then be brought
down upon the clay or other materials in the aforesaid states, pressing the same into
the tooth like forms which stand out or project, on the die, block or plate às
shown in section drawing marked B. thereby producing a tile, brick or briquette
back, as shown in section drawing marked A, which can be drawn, or lifted from
the aforesaid die, block or plate as shown in section drawing marked B.
And we further claim, that the order or process, of the aforesaid invention as
now shown to be performed, can be reversed, using the die, block or plate and
heretofore known as the bottom die, block or plate as shown in section drawing
marked B as the top die, block or plate producing a tile, brick, or briquette as
shown in section drawing marked A.
Having now particularly described the nature of our said invention and the
manner in which it is to be performed, we declare that what we claim is
That the backs of tiles, briquettes and the like, made in the manner herein
before described are novelties, seeing that although undercut, or incised at acute
angles, the aforesaid can be easily drawn from the block, plate, or die in the usual
process of manufacture, without the u or intervention of any separate pieces of

page_text: wood, metal or other substances which might be used to form, one or more undercuts
or incisions at acute angles as described.
Dated-this 23rd day of January 1897.
