JOIN NEWTON, Engineer, Vulcan Works, Longport, do hereby declare the nature
of this invention to be as follows:-
<<
This our invention has reference to improved dies, for use in making earthen-
ware or dust"
"slabs or tiles with undercut or dovetail recesses for facing walls
and other surfaces, and usually known as safety-back tiles.
In carrying this invention into practice we make use of dies used in making
plain tiles or slabs, by affixing either to the top or bottom die one or more straight
or curved metallic strips thereto by shellac or like suitable adhesive, such strips
being removed, when required to use such dies for making plain tiles, it of course
will be understood that such dies are attached to a fly-wheel, or like similar suitable
press in the usual way for making tiles with recesses in their back surface.

Improved Dies for Use in the Manufacture of Slabs or Tiles.
We, GEORGE ANTHONY MARSDEN, Dale Street, Burslem, Staffs, Tile Manu-
facturer, and JOHN NEWTON, Vulcan Works, Longport, Stoke-on-Trent, Staffs.,
Engineer, 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:-
This our invention has reference to improved dies for use in making slabs or
tiles of or from "dust" with one or more suitably shaped recesses or grooves in
their back surface, and usually known as safety-back tiles, the object of our said
invention being to enable slabs or tiles so recessed to be readily removed from the
die by which such recesses are formed.
In carrying our said invention into practice we make such dies of any suitable
shape; and size of or from cast-iron, cast-steel, cast-brass, wrought-iron, wrought-
steel or other similar suitable metal or metallic alloy with one or more wedge-
shaped brass, steel, iron or other suitable straight or curved detachable or remov-
able strips or projections attached to the moulding surface of the upper or lower
die used for making such slabs or tiles by means of shellac or other suitable
adhesive.

page_text: In order that our said invention may be more readily understood and explained
in detail we have hereunto annexed a sheet of drawings on which letters of reference
are marked indicating the various parts.
DESCRIPTION OF DRAWINGS.
Figure 1 is a side elevation of one shape of the body or bottom part of a metallic
die for a tile-press having detachable metallic strips attached by adhesive to its
upper surface, and Figure 2 is a plan view of the die and strips shewn at Figure 1,
three of such strips being of different shape and size.
On reference to the drawings hereto annexed a represents the body or block
of a metallic tile-die having four detachable metallic wedge-shaped strips b, c, d
ande attached to its upper surface by means of shellac or other similar suitable
adhesive.
It will be readily understood that such dies may be used as top or bottom dies,
and are attached in the usual way to the plunger of a fly-wheel press or other
suitable machine by means of a stalk f, and driven or worked by hand, or any
suitable motive power. After dust" slabs or tiles having a recess or recesses
formed in their back surface by using such dies, the tile or slab so formed is
readily removed from such dies by sliding the tile or slab in the direction indicated
by the arrow A.
One or more of the said straight or curved wedge-shaped metallic strips may be
affixed to each tile die by any suitable adhesive for forming a recess or recesses
in the back surface of tiles or slabs, the strips on each tile die if more than one
strip is used may be similar or of different sizes and shapes as shewn on the
drawings hereto annexed, and when such metallic strips have been removed from
such tile-dies, such dies may be used for making plain tiles or slabs.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
The method of readily adapting dies used for making plain back tiles or slabs
for use in making what are known as safety-back tiles or slabs by attaching to
such plain tile-dies any suitable number of straight, curved, or straight and
curved detachable wedge-shaped metallic strips of any suitable size by means of
shellac or similar suitable adhesive as herein substantially described and set
forth.
