PROVISIONAL SPECIFICATION.
Improvements in Paving Bricks, Paving and Facing Tiles, and
Quarries.
I, THOMAS PHILIP BAYLIS, Civil Engineer, of 3 Park Road, Redditch,
Worcestershire do hereby declare the nature of this invention to be as follows :-
An improvement in paving bricks, tiles, quarries, encaustic tiles (for floors or
walls) or any other brick or tile coming within the meaning of paving brick or tile,
the improvement is made by having the paving brick or tile grooved on one side
and one end, and on the other side and end of the brick or tile to be made with a
tongue so that each brick or tile shall dovetail or fit in each other so as to cause
the paving to be always an even surface, to secure them from rocking or tipping
out of their original position, and to thereby avoid the splashing up in wet
weather.
The tongue to be made a shade less in thickness than the groove so as to allow
its easy insertion, the groove to be made a third of the thickness of the brick or
tile, or any thickness that may be required to suit the various thicknesses of the
brick or tile..

COMPLETE SPECIFICATION.
Improvements in Paving Bricks, Paving and Facing Tiles, and
Quarries.
I, THOMAS PHILIP BAYLIS, Civil Engineer, of 3 Park Road, Redditch,
Worcestershire, 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 object of this invention is to obtain a true and even surface in pavements,
floors, wall linings, and other things which may be covered or faced with bricks
tiles quarries or other similar things, also to prevent them from becoming loose,
from tipping or rocking, also to prevent any soft material which may exist under
the pavement from oozing through in wet weather.
The manner in which I secure these objects is as follows:-In the brick or
tile or other article used for the purpose of paving covering or facing as before
mentioned, I form in the case of bricks or tiles either square or oblong or as the case
may require a groove on one side and one end, and on the other side and end of the
brick or tile I form a tongue slightly thinner than the width of the groove. In laying
the pavement or otherwise employing the article mentioned the tongues of one
brick or tile are slipped into the grooves of the bricks or tiles adjacent thereto.
By this means all the pieces become interlocked or dovetailed together, and the
tongues prevent any material which may be under the bricks or tiles from oozing
through the joints.
On the drawing accompanying this Specification,
Fig. 1 is a cross section of paving bricks or tiles shewing the tongue on one end
and the groove on the other end.
Fig. 2 is a plan shewing the groove by dotted lines and the tongue projecting.
Fig. 3 is a cross section shewing the tongue on one side and the groove on the
other side of the paving brick or tile.
Fig. 4 shews the position of the paving bricks or tiles when placed to form a
pavement or floor.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,
The application to bricks tiles quarries and other similar things used for paving
lining or facing, of tongues and grooves substantially as and for the purpose
hercinbefore described..
