PROVISIONAL SPECIFICATION.
Non-slipping Road Paving.
LEWIS CLEMENT Editor of the "Shooting Times" 2 Whitefriars Street, Fleet
Street, London, E.C. do hereby declare the nature of this invention to be as
follows:-
In the wood-blocks actually laid; or in the wood-blocks actually to be used for
road paving, alternate rows of holes (each hole one inch in diameter, and half an
inch in depth) to be drilled, and the said holes filled with rough granite cement,
trowelled perfectly level with the surface of the blocks, so as to prevent horses
from slipping, in wet weather.
In asphalte paving already laid, the said alternate rows of holes to be drilled; in
asphalte pavement actually being laid, the said alternate rows of holes to be
punched, an inch apart, as above, and filled, similarly as above, with rough granite
cement, thus giving a safe footing to horses, in slippery weather.
The rough granite cement to be, in all cases, trowelled perfectly level with the
wood or the asphalte surfaces.

COMPLETE SPECIFICATION.
Non-slipping Road Paving.
I, LEWIS CLEMENT, Editor of the Shooting Times," 2 Whitefriars Street,
London, E.C. 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 prevent the too frequent accidents to horses,
vehicles and human beings caused by the slippery nature of the materials now in
use for paving roads and streets.
Now according to this invention I pave roads and streets with wood blocks or
asphalte having holes therein filled with a mixture of cement and crushed granite,
marble chippings, firebrick or furnace slag to afford a good grip to the feet of
horses and other animals, pedestrians and the wheels of vehicles.
And in order that my invention may be fully understood I will proceed to
explain the same with reference to the accompanying sheet of drawings in
which
Figure 1 represents the upper surface of a wood paving block constructed
according to my invention.
Figure 2 is a section of same on line A. B. Figure 1.
Figure 3 is a section of a modified form of block hereinafter referred to.
The same letters denote the same parts in all the figures.
a is a wood paving block having holes 6 formed therein by drilling or punching
preferably by drilling, these holes are then tapped so as to form a female screw in
the bole as shewn at c Figure II. These holes are then filled with a mixture of
cement and crushed granite, firebrick, marble chippings, or furnace slag. The
granite, marble, or other material is crushed to about the size of ordinary peas, or
small enough to pass through a sieve or riddle of about three sixteenths or one
quarter of an inch mesh. The screw thread is used to prevent the mixture when
set from working out of the holes.
Or the wood blocks may be formed as above described and the holes filled with

page_text: plugs composed of a mixture of crushed granite, niarble, firebrick, or furnace slag
the said plugs being formed by moulding.
Or the holes in the wood blocks may be formed conical as shewn in Figure 3
with the smaller diameter upwards these holes are then filled with the mixture of
cement and other material herein before described and (as is also the case when the
screw threaded holes are used) the said mixture is finished off flush with the surface
of the block.
In applying my invention to asphalte paving already laid I drill holes therein
which may have screw threads formed therein and fill the said holes with the
mixture of cement and granite or other suitable material above described.
When applying my invention to asphalte pavements or roads in the course of
construction I provide suitable screwed or conical plugs of cement and granite or
other material which are placed in the asphalte at required distances apart.
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 :-
I. Constructing wood paving blocks and asphalte pavement with holes therein
the said holes being filled with a mixture of cement and crushed granite, marble,
firebrick, or furnace slag substantially as described and for the purpose stated.
II. Constructing wood paving blocks with conical holes or holes having a female
screw therein to receive a mixture of cement and crushed granite, marble, firebrick
or furnace slag substantially as described and for the purpose stated.
III. Constructing asphalte paving and roads with plugs formed of a mixture of
cement and crushed granite, firebrick marble or furnace slag inserted therein at
suitable intervals, substantially as described and for the purpose stated.
Dated this 14th day of February 1893.
