PROVISIONAL SPECIFICATION.
Improvements in Street Paving, having Special Reference to the
Covers of Apertures for Access to Underground Cavities.
We, PEARSON JACQUES JACKSON, of Grainger Street, Advertising Agent, and
ALFRED Fox, of Collingwood Street, Tobacconist, both in the City and County
of Newcastle-upon-Tyne, do hereby declare the nature of said invention to be as
follows:-
Our invention relates specially to paving the surfaces of the covers of access
shafts to sewers or other underground cavities, the objects being to provide a
pavement which will secure a better foothold and prevent accidents by slipping.
It consists in using blocks of natural or artificial stone, cement or other com-
position, or wood blocks, fitted in a frame, alone or in combination with other
substances or compositions, and having on their upper surfaces, which may be plain,
or, as we prefer, have in diagonal or transverse lines, or in any other way or shape,
cavities for the reception of some suitable substance or composition such as will
afford a "grip" for the feet over the entire surface.
As applied to cavities on the foothpaths or roadway such as for "coal-shoots,"
access boxes of telegraph or telephone wires, or other like underground openings,
we propose to fit the blocks into a frame in such manner that their upper surface
is flush or level with the surface of the flags or surrounding pavement, without any
metal appearing on said surface, which frame by suitable keys being introduced
can be bodily lifted. We may leave grooves or cavities between the blocks, open
so as to form a rough and secure foothold in walking over them, or may partially
fill them with some suitable substance or composition such as Stonoma" described
in P. J. Jackson's Patent No. 3429 of February 16 1893.

PEARSON JACQUES JACKSON Advertising Agent, 17 Grainger Street
Newcastle-on-Tyne and ALFRED Fox Tobacconist 26 Collingwood Street
Newcastle-on-Tyne 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 :-
Our invention, relates to paving the lids or covers of access boxes to any
underground aperture the object being to provide a surface securing a perfect foot-
hold and the prevention of accidents from slipping that are so common on the
metal or other surfaces at present used in street box or lid covers. It consists in
using blocks of natural or artificial stone wood cement or other composition such

page_text: blocks being fitted into a well-lid or frame the bottom of which frame may be solid
perforated or fully or partially open as is found necessary after taking into con-
sideration the position it is to occupy. Such blocks may be formed of one entire
piece or they may be used in sections in combination with any one or more other
substances and may where required have on their upper surfaces diagonal
transverse or other lines or be made leaving at intervals cavities or open spaces
which may be filled with any substance desired. When applied to openings in
footpaths or roadways such as coal shoots telegraph telephone or electric boxes
man holes pavement footlights cellar flaps sewers or other similar openings to
underground cavities we propose to fit the block or blocks into a well-lid or frame
made of metal or other material and in such a way that their upper surfaces are
level or flush with the surface of the surrounding pavement and that without any
metal or other material appertaining to or, being part of the well-lid or frame
coming to or appearing on the. top surface while the entire lid or frame and its
filling can be lifted from the cavity it covers by means of keys being inserted into
apertures provided for that purpose thus in cases where the bottom of the frame is
solid the cover is made air and watertight or the frame can be so made if desired
as to provide for purposes of ventilation. Where natural stone is used the
diagonal or transverse or other lines are unnecessary but they may if considered
necessary be cut in such stone and where artificial stone or other material is used
it is advisable to roughen the top surface in that way or preferrably to leave larger
and deeper cavities which may be filled in with any composition or substance say
such as that mentioned in P. J. Jacksons Patent No. 3429 of February 1893.
