WALTER AIRHART, OF HIGI-IMORE, SOUTH DAKOTA.

BIPRAP.

To all whom it may concern:

Be it known that I, TVALTER AIRHART, a citizen of the United States, residing at Highmore, in the county of Hyde and State of South Dakota, have invented certain new and useful Improvements in Riprap; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the protection of the banks of rivers and streams from being washed away by the current.

The particular device comprising this invention is commonly called a riprap. It is placed against the bank of a river or stream and by means of the protection it affords not only prevents the current from washing away the shore but also turns the channel and makes new land. This device is especially designed for use along such rivers as the Missouri where millions of acres of most valuable land have been cut away by the current.

My invention may also be employed for damming streams for the purpose of obtaining water power.

The main object of the invention is to provide a durable framework which will catch debris carried by the river and retain an accumulation of said debris thereon which will be suflicient to protect the bank from washing away and will ultimately form new land.

Another object is to reduce the expense of protecting such streams as the Missouri river.

My riprap is made in sections which can be conveniently placed in position at proper places along the side of the bank, each section consisting of a rigid framework suitably braced and carrying parallel strands of barbed wire placed at proper intervals, the general shape of the whole section being triangular in longitudinal vertical section. When in position, the hypotenuse of the triangle, which is substantially right-angular, rests upon the bottom of the stream, while the longer leg faces up stream and forms the front of the riprap when the debris has accumulated on it.

The invention also consists in the features of construction and combinations of parts hereinafter described and specified in the claims.

Specification of Letters Patent.

Application filed September 30, 1909.

Serial No. 520,300.

In the accompanying drawings illustrating the preferred embodiments of my invention: F igure 1 is a side View. Fig. 2 is a plan view. Fig. 3 is a rear end view. Fig. at is a plan view of the device in a river, and Fig. 5 is a sectional view of the river.

Referring more particularly to the drawing, 1 designates the rim, of the longer front side or leg of the riprap, which is preferably made of four inch pipes forming three sides of said rim, and the strip or plate 3 completing a rectangle. Said rim has longitudinal braces 2 and a cross brace 2 longitudinal braces project some distance in front of the plate 3 and are curved as at 8, so that their extremities lie flat on the bottom of the stream when the device is in position.

From the rear top edge of said rim 1 there extends a plurality of vertical parallel bent pipes 4 similar to those composing said rim. These bent pipes extend first vertically downward and thence horizontally rearward, the last named portions, designated 5 in the drawing, forming a part of the hypotenuse of the triangle. The remaining part of said hypotenuse is formed by strands of barbed wire as will be hereinafter explained. Two strips or plates, 6 and 7 respectively, are secured across the portions 5 of said bent pipes, one of said strips being arranged at the extreme rear end of the de vice and the other near the bend at the lower ends of the vertical portions of said bent pipes. Braces 8 connect the lower ends of the vertical portions of the outside bent pipes 41: to the sides of the rim 1 about midway thereof at the juncture of the cross brace 2 therewith. Other braces 9 extend from the points of attachment of the cross brace 2 horizontally to the vertical portions of the outside bent pipes of the rim. Another brace or pipe 10 is arranged crosswise from the junctures of the braces 9 with the bent pipes and is suitably secured to each of said bent pipes. Upon the framework thus formed, there are placed parallel strands of No. 7 barbed wire 11 at preferably three inches apart extending from the plate or strip 6 forwardly to the strips 7 and 3, thence upwardly and rearwardly to the apex of the device at the upper edge of the rim 1 and thence downwardly and rearwardly to the strip 6. The portions of these strands of wire 11 extending between the strips 3 and 7 complete the hypotenuse of the trian- The side and gle as noted above. Other strands of similar barbed wire 12 are secured to the strip 3 and pass first upwardly and rearwardly over the cross brace 2 of the rim 1, thence horizontally to the cross brace 10 and thence down wardly and rearwardly to the strip 6. The latter strands of barbed wire help to brace the device as well as accumulate debris. The section is moored to the shore by

cables

13 and 14 attached to the ends of the upper rear edge of the rim 1. When in position, as illustrated in Fig. 4:, the cable 13 nearest the bank is fastened to a stake 15 or other suitable projection. The other cable l l is fastened diagonally across the device and secured to another stake 16 on the bank farther up stream. The front strip or plate 3 is weighted down by rocks 17 or other suitable means. When the riprap has been in place for a time, roots, leaves, sand and waste matter will accumulate thereon from the current -and a most effective protection for the shore will be thereby afforded.

I claim:

1. The combination, with a device of the character described, which is triangular in longitudinal vertical section, of means to secure said device on the bed of a stream with one of its lateral edges arranged substantially parallel and in juxtaposition to the bank.

2. The combination, with a device of the character described, which is rectangular in plan and triangular in longitudinal, vertical section, of means to secure said device on the bed of a stream with one of its lateral edges arranged substantially parallel and in juxtaposition to the bank.

3. The combination, with a device of the character described, which is triangular in longitudinal vertical section, of means for securing said device 011 the bed of a stream with its longest side down and one of its lateral edges arranged substantially parallel and in juxtaposition to the bank.

4:. The combination, with a device of the character described, which is triangular in longitudinal vertical section, of means for securing said device on the bed of a stream with its longest side down, its next longest side facing upstream and one of its lateral edges arranged substantially parallel and in juxtaposition to the bank.
