Specification of Letters Patent.

Patented Aug. 24, 1915.

Application filed June 23, 1914. Serial No. 846,775.

To all whom it may concern: 1

Be it known that I, WILLIAM HENRY DEAN, a citizen of the United States, and a resident of Sioux City, in the county of l/Voodbury and State of Iowa, have invented a new and Improved Stream-Deflector, of

which the following is a full, clear, and exact description.

The invention relates to streamdeflectors for use in rivers and other waterways and such, for instance, as-shown and described in the Letters Patent ofthe United States, No. 1,080,049, granted to me on December 2, 1913. r

The object of the invention is to provide a new and improved stream deflector arranged to cause the current in the-waterway to form a building current and to prevent the current from digging into the shore or, bank of the waterway.

In order to accomplish the desired result use is made ofotwo aprons disposed vertically and extending at an acute angle one relatively to the other, the apex of the aprons being in the waterway a distance from the shore thereof and the aprons extending toward the shore, the lower edges of the aprons being spaced from the bottom of the waterway for the current to flow under the upstream apron and rise between the aprons to then flow downward and under the downstream apron.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of the stream deflector as applied; Fig. 2 is a cross section of the same; Fig. 3 is a sectional side elevation of the same.

The stream deflector consists essentially of two vertically-disposed aprons A and B extending at an acute angle one relatively to the other, the apex of the aprons being in the waterway C a distance from the shore C thereof and the aprons extending toward the shore. The aprons A and B are inclined at their lower edges to follow the bottom of the waterway, and the said lower edges are provided with openings or serrations A, B for the current to-flow through the openings A to rise between the aprons A and B and to then flow down adjacent the inner face of the downstream apron B to finally pass through the openings B the current thus forming a building current for forming a bar by depositing sand or other material below the apron B as inclicated in Fig. 3; When the water in the waterway is low the lower edges of the aprons A and B rest on the bed of the waterway C-but when the water rises the aprons A and B float and rise a distance which is limited by anchored flexible connections E and E of which the flexible connection E is attached to. the apex of the aprons and is connected with an anchor F embedded in the bed of the waterway C. The flexible connections E are connected with the shore ends of the aprons A and B and are attached to anchors F embedded in the bed of the waterway G. In case the water rises very high it can flow over the upper edges of the aprons A and B.

' 'In' order to hold the'aprons A and B in position against the force of the current, use

is made of flexible connections G and G connected with the ends of the aprons A and B and with anchors H and H arranged in the bed of the waterway on the upstream and downstream sides of the deflector, as will be readily understood by reference to Fig. 1. The aprons A and B are connected with each other at the upper edges by spaced beams I and I and braces I to give the desired rigidity to the aprons. Below the rear beam I is arranged a beam I and to thebeams I and I are secured vertically disposed slats I to provide a space between the shore ends of the aprons A and B for the reception of brush or similar filling material to prevent the current from cutting the bank at the shore line.

The apex end of the connected aprons A and B is provided with a box or shelf J containing rocks 'K or other weighting means to hold the stream deflector downward in proper relation relatively to the bed of the waterway O.

In constructing the aprons A and B use is preferably made of vertical planks at tached to transverse top and bottom beams, the lower ends of the planks being alternately longer and shorter so as to provide the openings or serrations A and B previously mentioned.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

1. A stream deflector, comprising conand adapted to be set in thewaterway transversely to the current therein with the apex end in the waterway a distance from the shore, the aprons being connected by transverse partition formed of upper and lower beams and vertical spaced slats and forming a space for a fillingmaterial, the lower edges of the aprons being spaced from the bed of the waterway for the. current to flow under the aprons to form a building 'curren'tfor forming a sand bar a distance-down stream beyond the apron. i,

' 3; stream deflector, comprising connected vertically disposed aprons set in the waterway-transversely to the current'there'iii an diverging 50m a edmindn point in the waterway toward the back thereof, the lower edges of the aprons being for the current to fiow through the said apron to form a ,4. A stream deflector, comprising connected and; Vertically disposed aprons arranged at an angle to each other and adapted to beset in the waterway transver'sely to the current, each apron comprising upper and lower beams'and verticalboards-secured to thebeanis with alternate boards eXtending below the lower beam, and means for anchoring the deflector whereby it can rise; and fall with the water of the waterway; I y

In testimony whereof I have signed my nameto this specification. iii the presence of two subscribing witnesses; I
