PROVISIONAL SPECIFICATION.
Improvements in Blocks or Slabs for Paving and other Purposes.
I ALEXANDER MOLEAN of 20 Reservoir Road, Brockley in the County of Surrey,
Cement Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide a non slipping surface for blocks or
slabs of concrete, artificial stone, or other material for paving and other like purposes.
In carrying out my invention, I prefer to manufacture the blocks or slabs by
pressure in porous moulds in the manner described in the specification of Letters
Patent granted to me, and dated June 9th 1884, No. 8747, but I do not intend to
confine myself to such mode of manufacture.
The non-slipping surface consists of rings, strips, or small blocks of lead, zinc, or
other suitable material, which are let into the slab or block during manufacture, and
lie flush with the surface.
These rings, strips, or blocks will be placed in the slab from two to three inches
apart, or they may be arranged in patterns. They may be also arranged to give the
name of a street or a railway station, or in any other convenient manner.
The strips, rings, or blocks wear down evenly with the slab, and will always preserve
its non slipping properties.
Although I have more particularly referred to concrete or artificial stone slabs or
blocks, the invention will be equally applicable to asphalte.

COMPLETE SPECIFICATION.
Improvements in Blocks or Slabs for Paving and other Purposes.
I, ALEXANDER MCLEAN, of 20 Reservoir Road, Brockley in the County of Surrey,
Cement Manufacturer, 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 provide a non-slipping surface for blocks or slabs
of concrete, artificial stone, or other material for paving and other like purposes.
In carrying out my invention, I insert rings, strips, or small blocks of lead,
zinc, or other suitable material, in the slab or block, during manufacture, so that they
will lie flush with the surface. These rings, strips, or blocks will be placed in the slab
at from two to three inches apart, or, they may be arranged in patterns. They may
be also arranged to give the name of a street or a railway station, or in any other
convenient manner.
The strips, rings, or blocks will wear down evenly with the slab, and will always
preserve its non-slipping properties.
Although I have more particularly referred to concrete or artificial stone slabs or
blocks, the invention will be equally applicable to asphalte.
In the accompanying drawing, I have shown, at Fig. 1, the face of a slab fitted with
the non-slipping material; Fig. 2 being a longitudinal vertical section on the line x, x,
Fig. 1. A represents the slab, and B, C, D, the rings, block, and strip.-These pieces
are let into the slab or block for any desired depth, but in general will not exceed half
an inch, and where the traffic is not great, it may be much less.

page_text: 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
1 claim is:
The production of a non-slipping surface for blocks or slabs as herein shown and
described.
