PROVISIONAL SPECIFICATION.
An Improved Method of Laying Wood Pavements.
I, FRIEDRICH MILLER, of Bockenheim, near Frankfort on the Main, in the
Empire of Germany, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to the production of a wood pavement which is not
easily deteriorated by outer influences and consists in a method of laying such a
pavement.
I have found that iron cement made substantially of pulverized iron, sulphur
and sal-ammoniac water will under the action of moisture enter wood which has
been coated with the same, settle in its pores and harden so that a more or less
deep layer at the surface of the wood will form a hard crust which protects the
wood from decaying by the action of the atmosphere, and which moreover wears
very little or not at all by reason of its hardness.
According to my said invention wood blocks are bedded on a foundation con-
sisting of a mixture of pulverized iron (iron filings) sulphur and sal-ammoniac, so
much water with some vinegar having been added to this mixture as is necessary
to render the material very plastic. It is expedient to use a sufficiently large
quantity of water in order that the material shall not harden too rapidly and have
time to enter the pores of the wood. With the said mixture the joints between
the several blocks are filled up and finally the finished pavement receives a thin
coating of the same material.
.
This coating is pressed into the fibre of the wood by means of a roller or other
apparatus, enters the pores of the wood, hardens therein and also on the outer
surface of the pavement, which thus receives all round a crust which protects it
from decay and against wear. The crust surrounding the wood is as hard as iron,
therefore by my method the advantages of iron and wood pavements are combined
in a very effectual manner.
To the above mentioned mixture may be added other materials, more especially
finely ground silicate.
In lieu of sulphur, use may also be made of other substances which by the
action of alkaline lyes will form with iron solid and insoluble compounds.

COMPLETE SPECIFICATION.
An Improved Method of Laying Wood Pavements.
I, WILHELMINA FRANZISKA MÜLLER of 24 Christ Church Road Folkestone
in the County of Kent, Administratrix of the late Friedrich Miller, of Bockenheim
near Frankfort-on-the-Main in the Empire of Germany, and lawful Attorney of
Rosa Therese Maria Gabriele Miller, the widow of the said Friedrich Miller 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:-
This invention relates to the production of a wood pavement which is not
easily deteriorated by outer influences and consists in a method of laying such a

from decaying by the action of the atmosphere, and which moreover wears very

According to my said invention wood blocks are bedded on a foundation con-

surface of the pavement which thus receives all round a crust which protects it
from decay and against wear. The crust surrounding the wood is as hard as iron
therefore by my method the advantages of iron and wood pavements are combined
in a very effectual manner.
To the above mentioned mixture may be added other materials more especially
finely ground silicate, such as silicate of magnesia, silicate of manganese, silicate
of potash, the choice being only regulated by the cost of the material.
In lieu of sulphur, use may also be made of other substances which by the
action of alkaline lyes will form with iron solid and insoluble compounds, as for
example, sulphate of alumina, sulphate of potash and all sulphuret combinations.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
The method of laying wood paving which consists in bedding the wooden blocks
on a mixture of finely comminuted iron sulphur vinegar water, and sal-ammoniac,
sometimes with the addition of pulverized silicate and filling the interstices between
the blocks with the mixture the upper surfaces of the said blocks when laid in
place being impregnated with the aforesaid mixture by forcing same into them by
means of a roller substantially as and for the purpose hereinbefore described.
