Improvements in and relating to Tiles, Mosaics or the like and
Means for Interlocking same.
I, HENRY FITZROY WEBB, Gentleman, residing at Greensburg, in the County of
Westmoreland and State of Pennsylvania, United States of America, do hereby
declare the nature of this invention to be as follows:-
This invention relates to mosaic-work and most especially to the elements-
tiles comprising the same. The primal object of the invention is the provision
of a tile which will have a porous backing fused thereto and of a kindred nature
to the stucco, whereby the bed is homogeneous and the tile prevented from leaving
the bed when subjected to stress or a smart blow which frequently is the case.
The tile when finished is a complete structure comprising a facial layer of glass
or porcelain, a porous backing constituting a rear or inner layer, and an inter-
mediate bonding layer caused to adhere to the facing and backing by fusion. In
order that there may be a positive interlocking between the tile and the stucco,
the backing of the tile has keys formed therein.
For a full description of the invention and the merits thereof and also to
acquire a knowledge of the details of construction of the means for effecting the
result, reference is to be had to the following description.
While the essential and characteristic features of the invention are necessarily
susceptible of modification, still the preferred embodiment of the invention is
described as follows:-
The tile proper may be a slab, tablet or block of glass, porcelain or kindred
vitrified material and may be of any desired size, shape and thickness. This
tile is strengthened and braced by a backing of porous material fused thereto
be being baked at a relatively low temperature.
The backing is composed of any good cement and enough flux to give it
body but not enough to impart a glaze thereto. The cement and flux when
mixed are applied to the rear side of the tile and form the backing. This
backing is baked at a comparatively low temperature to fix it by fusion The
fused joint constitutes a layer intermediate of the tile and backing.
The tile in its general character is a composite structure, being composed of
an intermediate and outer layers, the said layers being secured together by
fusion. The porous backing is well adapted to co-operate with the stucco,
because-of-the-affinity_of_the_two_substances, whereby a firm bonding is effected
when the tile is properly positioned and applied. The backing of the tile and the
stucco become homogeneous in the formation of the mosaic.
A key may be provided to form a positive interlocking connection between the
tile-and-bed or stucco. This key-may-consist of a series of depressions in the outer
face of the backing formed therein while the composition is still plastic and
prior to the baking operation. These diaphragms may be of any form and are
preferably undercut to retain the stucco or plaster forming the bed for the mosaic-
work.

page_text: In another form the key consists of a series of pyramidal-shaped projections
formed by intersecting grooves or channels having a relative right angular
disposition. This arrangement provides an adhering surface of greater superficial
extent than the tile because of the sloping sides of the projections.

Improvements in and relating to Tiles, Mosaics or the like and
Means for Interlocking same.
I, HENRY FITZROY WEBB, Gentleman, residing at Greensburg, in the County of
Westmoreland and State of Pennsylvania, of the United States of America, 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 invention relates to mosaic-work and most especially to the elements-
tiles comprising the same. The primal object of the invention is the provision
of a tile which will have a porous backing fused thereto and of a kindred nature
to the stucco whereby the bed is homogeneous and the tile prevented from leaving
the bed when subjected to stress or a smart blow which frequently is the case.
The tile when finished is a composite structure comprising a facial layer of glass
or porcelain, a porous backing constituting a rear or inner layer, and an inter-
mediate bonding layer caused to adhere to the facing and backing by fusion. In
order that there may be a positive interlocking between the tile and the stucco,
the backing of the tile has keys formed therein.
For a full description of the invention and the merits thereof and also to
acquire a knowledge of the details of construction of the means for effecting the
result, reference is to be had to the following description and the drawings hereto
attached.
While the essential and characteristic features of the invention are necessarily
susceptible of modification, still the preferred embodiment of the invention is
illustrated in the accompanying drawings, in which:-
Fig. 1 is an edge view of a tile constructed in accordance with this invention.
Fig. 2 is a similar view showing the manner of forming the key.
Fig. 3 is a view of the rear side of a tile showing a different formation of key.
The tile 1 proper may be a slab, tablet or block of glass, porcelain or kindred
vitrified material and may be of any desired size, shape and thickness. This
tile is strengthened and braced by a backing 2 of porous material fused thereto
by being baked at a relatively low temperature.
The backing 2 is composed of any good cement and enough flux to give it body
but not enough to impart a glaze thereto. The cement and flux when mixed
are applied to the rear side of the tile and form the backing. This backing is
baked at a comparatively low temperature to fix it by fusion. The fused joint 3
constitutes a layer intermediate of the tile and backing.
The tile in its general character is a composite structure, being composed of
an intermediate and outer layers, the said layers being secured together by
fusion. The porous backing is well adapted to co-operate with the stucco,
because of the affinity of the two substances, whereby a firm bonding is effected

page_text: when the tile is properly positioned and applied. The backing of the tile and the
stucco become homogeneous in the formation of the mosaic.
As shown in Fig. 2 a key may be provided to form a positive interlocking
connection between the tile and bed or stucco. This key 4 consists of a series of
depressions in the outer face of the backing 2, formed therein while the com-
position is still plastic and prior to the baking operation. These depressions
may be of any form and are preferably undercut to retain the stucco or plaster
forming the bed for the mosaic-work.
As shown in Fig. 3 the key consists of a series of pyramidal-shaped projec-
tions 5 formed by intersecting grooves or channels having a relative right angular
disposition. This arrangement provides an adhering surface of greater super-
facial extent than the tile because of the sloping sides of the projections 5.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
-
1. A composite tile composed of a facial layer of vitrified material and a stucco
backing fused thereto, said backing being formed of cement and a flux and
applied to the facial layer in a plastic state.
2. A tile consisting of a vitrified tablet or slab and a stucco backing affixed
to the tablet by fusion and having a series of projections at its rear side said
stucco comprising cement and a flux and applied to the tablet in a plastic state.
