3 Claims. (Cl. 61--28)
A double system of triangularly disposed bars
is employed for reinforcing the framework I5.
Thus, the adjoining end portions of the sec—
This invention relates to dams and more par
ticularly to movable dam structures of the roller
type.
An object of the invention is to provide an im
5 proved movable dam structure in which the
damming element consists of a front wall formed
of ?at sheets of plate steel, which wall is sup
ported from a rotatable hexagonally shaped
torsion-proof skeleton frame adapted to be oper
10 ated from only one end.
Another object of the invention is to provide
an improved movable dam-v structure of the above
type in which the front damming wall consists
of a central substantially vertically disposed sec
15 tion and upper and lower rearwardly inclined
sections, all of the sections of the front wall being
supported from a skeleton framework hexagonal
ly shaped in cross section, and one of the sides
of which abuts the central section of the front
wall and has substantially the same width as the
2
width of the central section of the front wall.
With the foregoing and other objects and ad
vantages in view, the invention consists in the
preferred construction and arrangement of the
N On several parts which will be hereinafter fully de
scribed and claimed.
In the accompanying drawings:
Figure 1 is a front elevation of a movable dam
structure embodying the present invention, the
30 supporting structure therefor being shown in
section;
Fig. 2 is a rear elevation;
Fig. 3 is a vertical transverse section taken on
the line 3—3 of Fig. 1; and
Fig. 4 is a horizontal section taken on the line
4-4 of Fig. 3.
Referring to the drawings, the movable dam
structure comprises a front wall II formed of
three sections, including a central section I2, an
40 upper section l3 and a lower section [4. When
the device is in damming position, as shown in
Fig. 3, the central section I2 is adapted to be sub
stantially vertically disposed, and the upper and
lower sections I2 and M, respectively, are adapted
to extend at an angle rearwardly or downstream
from the central section I2.
For the purpose of supporting the front wall
II, I utilize a structural steel framework l5
which is hexagonal in cross section.
The framework I5 has a front side IE, to which
is secured the central section I 2 of the front wall
II, and ?ve other sides, indicated at I1, l8, I9,
20 and 2i, Fig. 3. The sides of said framework
each have a breadth corresponding substantially
to the breadth of the central section I2.
tions l1 and [B are connected to the adjoining
end portions of the sections i6 and 2! by bars 22
and to the adjoining end portions of the sections
!9 and 28 by bars 23.
-
The adjoining end portions of the sections 56
and 2| are connected to the adjoining end por
tions of the sections 19 and 20 by bars 24.
V
The bars 22, 23 and 24 are arranged in the
form of a triangle.
The adjoining end portions of the sections 16
and I‘! are connected to- the adjoining end por
tions of the sections 20 and 2: by bars 25, and to
the adjoining end portions of the sections l8 and
I9 by bars 26.
The adjoining end portions of the sections i8
and i9 are connected to the adjoining end por
tions of the sections 20 and 2| by bars 27.
The bars 25, 26 and 21 are arranged in the
form of a triangle, similar in size to the triangle
formed by the bars 22, 23 and 24, said triangles,
however, being so disposed within the device that
the apexes thereof are disposed equal distances
apart and the sides of one triangle cross the sides
of the other triangle in such a manner that a
hexagonally shaped opening is formed longitudi
nally through the center of the device by the bars
22 to .21, inclusive, as shown in Fig. 3. The
braces 22 to 21, inclusive, are all of substantially
the same length and connect the apexes of the
several sides of the hexagonally shaped frame
work.
The sections l3 and M of the front wall of the
device are supported from the framework l5 by
struts 28 and 29, respectively.
.
Mounted on each end of the framework 15 are
cylindrical end sections 30 and 3! (see Fig. 2) , in
the form of drums.
40
Both end sections 30 and 3| carry toothed seg
ments, indicated at 32 and 33, respectively,‘the
teeth of which segments are adapted to mesh
with the teeth of inclined tracks 34 and 35, re
spectively, so as to guide the movable dam struc
ture in a straight path when the same is being
raised or lowered.
The movable dam structure is adapted to be
raised and lowered by rolling the same up and
down the inclined tracks 34 and 35, said struc
ture being operated only from one end by means
of a chain 36 (Fig. 3), the upper end of which is
connected to suitable hoisting mechanism (not
shown). The double triangularly shaped frame

As shown in Fig. 1 the frontwall of the device A claim is:
1. A movable dam structure comprising a front 10

In fact, the whole device, with the exception of wall having a ?at central longitudinal section
the toothed segments 32 and 33, and the toothed
adapted to be disposed in a substantially vertical

plane when the dam is in damming position, up
tural steel shapes in the form of channels, angles,
15 beams, and sheets of plate steel, the several parts
being united into an integral structure by welding
the joints therebetween.
The end sections 30 and 3| are connected to the
extremities of the framework l5 by brackets 38,
20 as shown in Fig. 4, said brackets preferably being
formed from plate steel sheets and angles.
At each end; the movable. dam structure car
ries a flap 39 (Figs. 3 and 4) adapted to engage
the adjacent wall structure of the dam and there
25 by seal the joints between the ends of the mov
able dam structure and the wall structure.
Also, the lower edge of the section M is formed
with a sealing strip 40 for engaging the sill of the
dam and thereby seal the joint along the bottom
30' of the movable dam structure.
The movable dam structure is adapted to be
disposed transversely across a stream, being con
?ned between stationary end walls 4| and 42, as
shown in Fig. 1. In cases where the breadth of
35 the streams are extensive, two or more, movable
‘dam structures may be employed, and in such in
stances the intermediate stationary end walls. can
be in the form of piers with niches on the opposite
sides thereof for the end portions of the movable V
v40 dam structures.
The framework I5 is' enclosed throughout its
length by sheets of plate steel 43 so as to prevent
foreign matter such as logs, branches of trees,
and the like from lodging in the framework when

or damming position.
