I, WILHELM GÜRTLER of Vassily Ostroff, 14th Line, No. 5, St. Petersburg, Russia,
Engineer do hereby declare the nature of this invention to be as follows:-
Asphalte has heretofore been used for covering floors, roadways, roofs, and also for
pipes of moderate length and diameter, but it has not been possible to employ it for
independent structures such as large tanks, walls, ceilings, columns, and the like.
According to the present invention asphalt is applied for the construction of such
independent structures by combining therewith a woven metallic framework. For
this purpose a pattern or ternplate of the article to be produced is made of wood, by
the aid of which a metal framework by preference of iron and wire, is woven in such
manner that the pattern forms a core between which and the framework sufficient
space is left for forming the inner coating of asphalte on the latter, the asphalte being
then applied hot both on the inner and the outor surface of the framework, between
the interstices of which it is pressed.
When the asphalte has cooled and solidified the cores are removed and the surfaces
are smoothed if necessary and coated with hot asphalte, varnish when used as tanks
pits or pipes. The strength of the metal framework and thickness of the enclosing
asphalte covering will vary according to the purpose to which it is applied.
The metal framework for prismatic or circular tanks, conduits, pipes, and railway
sleepers may consist of two helices of wire wound in opposite directions, between
which are arranged at distances apart vertical or longitudinal bars or rods securely
woven in at the points of intersection of the helices. Such framings withstand strains
or pressures in all directions.
In the case of objects with flat surfaces such as slabs, walls, ceilings &c. the frame-
work consists of longitudinal and transverse wires interwoven at their points of
intersection.
In forming slabs and pipes the hot asphalte is introduced into moulds containing the
metal framing and is then subjected to pressure in the same, either by hand or suitable
power. In certain cases these structures may be made in situ by means of moveable

page_text: moulds or ternplates. Railway sleepers may also be made in the same manner as
slabs and pipes, and they may be supported when placed in position by firmly
imbedding them in the permanent way. Pits may be constructed as shown at fig. 7
of the accompanying drawings being entirely enclosed, with hermetically closed
openings and be provided with pumps for emptying their contents without requiring
to be opened.
Such structures while affording the requisite strength will also have a certain degree
of elasticity and will be exceedingly cheap, and durable and at the same time easily
and quickly made.
On the accompanying drawings are shewn by way of example various structures
constructed according to my above described invention.
For the sake of clearness the metallic helices are shewn single, although in reality
they are made double as above explained.

page_text: Structures Formed of Asphalte and Metal Framework in
Combination.
I, WILHELM GURTLER of Vassily Ostroff 14th Line, No. 5, St. Petersburg, Russia,
Engineer, 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:-
Asphalte has heretofore been used for covering floors, roadways, roofs and also for
pipes of moderate length and diameter, but it has not been possible to employ.
it for independent structures such as large tanks, walls, ceilings, columns and
the like.
According to the present invention asphalte is applied for the construction of such
independent structures by combining therewith a woven metallic framework.
For this purpose a pattern or tern plate of the article to be produced is made of
wood by the aid of which a metal framework by preference of iron and wire, is woven
in such manner that the pattern forms a core between which and the framework
sufficient space is left for forming the inner coating of asphalte on the latter, the
asphalte being then applied hot both on the inner and the outer surface of the framework,
between the interstices of which it is pressed.
When the asphalte has cooled and solidified the cores are removed and the surfaces
are smoothed if necessary and coated with hot asphalte, varnish when used as tanks,
pits or pipes. The strength of the metal framework and thickness of the enclosing
asphalte covering will vary according to the purpose to which it is applied.
The metal framework for prismatic or circular tanks, conduits, pipes, and railway
sleepers may consist of two helices of wire wound in opposite directions between which
are arranged at distances apart vertical or longitudinal bars or rods securely woven in
at the points of intersection of the helices.
Such framings withstand strains or pressures in all directions.
In the case of objects with flat surfaces such as slabs, walls, ceilings &c. the frame-
work consists of longitudinal and transverse wires interwoven at their points of
intersection.
In forming slabs and pipes the hot asphalte is introduced into moulds containing
the metal framing and is then subjected to pressure in the same either by hand or
suitable power.
In certain cases these structures may be made in situ by means of moveable moulds
or ternplates.
Railway sleepers may also be made in the same manner as slabs and pipes, and they
may be supported when placed in position by firmly imbedding them in the permanent
way.
Pits may be constructed as shewn at fig. 7 of the drawings accompanying my
Provisional Specification being entirely enclosed with hermetically closed openings

page_text: and be provided with pumps for emptying their contents without requiring to be
opened.
Such structures while affording the requisite strength will also have a certain degree
of elasticity and will be exceedingly cheap and durable and at the same time easily
and quickly made.
On the drawings accompanying my Provisional Specification are shewn by way of
example various structures constructed according to my above described invention.
For the sake of clearness the metallic helices are shewn single, although in reality
they are made double as above explained.
Figure 1 shews a longitudinal section and plan of a flat or curved structure for
floors.
Figure 2 shews a section of an asphalte slab with wire framework imbedded
therein.
Figure 3 shews the mode of constructing pipes.
Figure 4 shews a perspective view of a railway sleeper and Figure 5 shews the
application to roofing tiles and to a floor.
Figure 6 shews a longitudinal and transverse section of a casing for coffins.
Figure 7 shews a section of a pit for water closets &c. and Figure 8 shows a
perspective view of the method of forming tanks and pipes.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The herein described improved manufacture of structures consisting of a combination
of metal framework and asphalte.
