I ANTON HARTMANN Junr. of Frankfort on the Main, in the Empire of Germany
do hereby declare the nature of this invention to be as follows:
This invention relates to dams or dikes for preventing the encroachment of rivers,
lakes, seas or the like, and protecting the adjoining land against inundation. Along
the banks or shores to be protected, iron standards are firmly secured at suitable
distances so that they will offer sufficient resistance against the pressure of large-
masses of water. This can be effected by letting the lower end of the said standards
and the end of the struts supporting them into masonry_or concreting; the standards
can howevor be fixed in any other suitable manner. The several standards are not
connected with each other except by a stone socle or base which extends on the ground
at their foot. At their two inner sides the standards are provided with grooves or
channels designed to receive the lateral edges of an iron plate which is reinforced by
angle iron rivetted to it and forms a watertight wall by which the bank or shore is
protected against inundation. The plates slid between every two standards can be
made of several parts the lower edge of the lowest part being placed upon the
aforesaid socle or base and the lower edge of the following part or parts
being inserted in a channel between anglo irons rivetted to the upper edge of the
part beneath, so that all the parts together constitute a closed wall. The height of
the standards and of the plates slid between them can of course be varied. It depends
on the level of the land to be protected and in the case of a river on the size thereof
and on the masses of water which it may convey under abnormal conditions.
In order to keep the bank or shore free from obstructions the said plates are usually
removed from between the standards and put in a convenient place. In case of
danger from inundation the plates are slid between the standards, all the lover parts
being first put in their place, then all the parts immediately above the lowest and so
on thus increasing the height of the dam or dike as the water rises.
-

page_text: As soon as the danger from inundation may be regarded as past, and the river or
the like has fallen again to its normal level, the plates can be removed again to keep
the banks or shore free. If no importance is attached to the last mentioned point, the
plates constituting a wall can of course be permanently connected with the standards
so that the wall is stationary.

J, ANTON HARTMANN, the younger, of Frankfort on the Main, Germany, 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 dams or dikes for preventing the encroachment of rivers,
lakes, seas or the like, and protecting the adjoining land against inundation.
The accompanying drawing shows a dam or dike constructed according to the said
invention, the figures being hereinafter referred to.
Along the banks or shores to be protected, iron standards A are firmly secured
at suitable distances so that they will offer sufficient rosistance to the pressure of large
masses of water. This can be effected by lotting the lower end of the said standards A
and the end of the struts supporting them into masonry or concreting M; the
standards can, however, be fixed in any other suitable manner. The several standards
are not connected with each other except by a stone socle or base C which extends
along the ground. At their two inner sides the standards, as shown in Figure 3, aro
provided with grooves or channels designed to receive the lateral edges of an iron
plate B, which is reinforced by angle-iron riveted to it, and forms a water-tight wall,
by which the bank or shore is protected against inundation. The plates B slid between
every two standards can, as shown in Figure 2, be made of several parts, the lower edge
of the lowest part being placed upon the aforesaid socle or base C, and the lower edge of
the following part or parts being inserted in a channel between angle-irons riveted
to the upper edge of the part beneath, so that all the parts together constitute a closed
wall. The height of the standards and of the plates slid between them can of
course be varied. It depends on the level of the land to be protected, and, in the
case of a river, on the size thereof and on the masses of water which it may
convey under abnormal conditions.

page_text: In order to keep the bank or shoro free from obstruction, the said plates B are
usually removed from between the standards A and put in a convenient place. In
case of danger from inundation, the plates are slid between the standards, all the
lower parts being first put in their place, then all the parts immediately above
the lowest and so on, thus increasing the height of the dam or dike as the water
rises.
As soon as the danger from inundation may be regarded as past, and the river
or the like has fallen again to its normal level, the plates B can be removed again
to keep the banks or shore free. If no importance is attached to the last-mentioned
point, the plates B constituting a wall can of course bo permanently connected with
the standards A so that the wall is stationary.
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 ;-
An iron protecting dike, consisting of the stationary standards A arranged at
certain angular distancos on the bank or shore to be protected, which standards are
provided at their inner side with grooves into which are slid the transportablo
walls B consisting of thick sheet-iron and strengthened by angle-irons riveted
thereto, the said walls consisting of one or more parts, and forming eventually a
firm connection of the standards A with the walls B.
