Year: 1876

City of London, for the Invention of "IMPROVEMENTS IN MEANS FOR THE
PREVENTION OF SLIPPING ON ROADWAYS, FOOTWAYS, STEPS, LANDINGS, AND
OTHER SIMILAR THOROUGHFARES AND PLACES."
PROVISIONAL SPECIFICATION left by the said Charles William Hoe at
the Office of the Commissioners of Patents on the 19th February 1876.

MENTS IN MEANS FOR THE PREVENTION OF SLIPPING ON ROADWAYS, FOOTWAYS,
STEPS, LANDINGS, AND OTHER SIMILAR THOROUGHFARES AND PLACES."
It is
This Invention has for its object the introduction of means for preventing the
slipping of horses and pedestrians in passing along roadways, footways, steps,
landings, and other similar thoroughfares and places, whether the same be paved
with asphalte, stone, wood, iron, or concrete; but it is more especially designed to
prevent the slipping of horses upon roads covered with asphalte, and consists in
introducing at suitable distances while the asphalte is soft, plugs of lead, of about
half to three-quarters of an inch (more or less) square, or in diameter.
preferred that these plugs shall be made rather larger at the base than at the top,
and that they shall be so long that when inserted they shall lic a little above the
surface of the asphalte, so that when the latter is cold and hard a few blows of a
hammer will bring the surfaces of, the lead and asphalte flush, and by swelling the
lead in diameter cause the plug to retain a firm hold. The course of proceeding is
very similar when the road or footway is made of concrete.
When the paving is of stone or wood it will be necessary to drill or otherwise
form holes in it of suitable depth and at the requisite intervals, and to fill the holes
so made with plugs of lead, as before described, the holes in such case being undercut
or not, as may be found expedient.
In the case of paving of footways, curbs, or gutters with iron, the plates may
be cast with holes in them, of such size and shape as may be found most
convenient.
Although lead is the metal of which it is preferred to make the plugs the
Invention is not limited thereto, as they may be made of copper or any other
suitable metal or alloy.

It is
This Invention has for its object the introduction of means for preventing the

with asphalte, stone, wood, iron, or concrete; but it is more especially designed to

introducing at suitable distances while the asphalte is soft plugs of lead, of about
half to three-quarters of an inch [more or less] square, or in diameter.
preferred that these plugs shall be made rather larger at the base than at the top,
and that they shall be so long that when inserted they shall lie a little above the
surface of the asphalte, so that when the latter is cold and hard a few blows of a
hammer will bring the surfaces of the lead and asphalte flush, and by swelling the
lead in diameter cause the plug to retain a firm hold. The course of proceeding is
very similar when the road or footway is made of concrete.
When the paving is of stone or wood it will be necessary to drill or otherwise
form holes in it of suitable depth and at the requisite intervals, and to fill the boles
so made with plugs of lead, as before described, the holes in such case being undercut
or not, as may be found expedient.
In the case of paving of footways, curbs, or gutters, with iron, the plates may
be cast with holes in them, of such size and shape as may be found most
convenient.
Although lead is the metal of which it is preferred to make the plugs the
Invention is not limited thereto, as they may be made of copper or any other
suitable metal or alloy.
In order that the foregoing may be more easily understood, Drawings are attached
hereto, of which the following is a description:-Figs. 1 and 2 are plans of the
asphalte road A, A, with the leaden plugs B, B; Fig. 3 is a section of such a road-
way; A being the asphalte; B, B, the metal plugs; C, the concrete foundation for
the asphalte; and D, the soil.
The Invention is not confined to the shape of the plugs in plan, as they may be
square as in Fig. 1, or round as in Fig. 2, or they may be hexagonal, or any other
suitable form; nor is it limited to the distances the plugs shall be apart, as variations
may be found desirable under different circumstances.
Having now described and particularly set forth the nature of this Invention, and
.the manner in which the same is or may be used or carried into effect, I would observe
in conclusion that I do not confine or restrict myself to the precise details or arrange-
ments which I have described or referred to, as variations may be made therefrom
without deviating from the principles or main features of this Invention, but what
I consider to be novel and original, and therefore claim as the Invention secured to
me by the herein-before in part recited Letters Patent is, the construction of
roadways and footways in which metal plugs are inserted in the material of which
the upper surface of the road or footway is composed, as described, and shown on
the Drawings.
In witness whereof, I, the said Charles William Hoe, have hereunto set
my hand and seal, this Eleventh day of August, in the year of our Lord One
thousand eight hundred and seventy-six.
