To all whom it may concern:

Be it known that we, JAMES M. MAHER and EDWARD BIGNELL, citizens of the United States, residing, respectively, at Fremont, in the county of Dodge, State of Nebraska, and at Lincoln, in the county of Lancaster tain new and usefullmprovements in Combination Land-Reclaiming. and Current- Controlling Means for Silt-BearingStreams, of which the following is a specification.

This invention relates to a combination landreclaiming means and current-control for silt beaki'ing streams, and has for its object to provide asystem by means of which the bed of silt-bearing streams may be narrowed and maintained-within a channel of well defined limits, the silt being deposited to fill that part of the bed not occupied-by the channel, and to fill the low lands adjacent to the stream, thereby reclaiming the low lands so that they will not be subject to overflow.

Some of the larger silt-bearing streams carry volumes of water during all parts of the year sufficient for purposes of navigation, but on account of the formation of sand bars and changes in the course of the main current of the stream, navigation has not been. practical; also large areas of land along the course of these streams are sub-' 'ject to periodical overflows, which renders them unfit for cultivation. By use of the herein described system, the stream may be.

narrowed and confined to a channel of substantially uniform width,so that navigation will be practical, the silt, at times of overfio w, being depositedupon the low lands to cause their reclamation.

vThe invention consists of the novel construction, combination and arrangement of parts as described. herein and claimed, and as illustrated in the drawings, it being understood that changes in form, size, proportion and minor details may be made within the scope of the claims without. departing from the spirit of the invention, or sacrificing any of-"its advantages.

In the drawings, Figure 1 is a plan view of a silt-bearing stream and an arrangement of levees, barriers or dikes,,and parts ported bythe dikes. Fig. 2 is a vertical sec-' tion on line a a of Fig. 1. Fig. 3 is a vertical section on line 0 0 of Fig. 2. Fig. 4 is a vertical section on line d d ofFig. 2. Fig.

5 is a vertical section on line 6 e of Fig. 1 a part of the fascines and cables bein JAMES M. MAKER, OF FREMONT, AND EDWARD BIGNELL, OF LINCOLN, NEBRASKA. I

omitted. Fig. 6' is a plan view of one o' the metallic sections for the piers or caissons. Fig. 7 is a vertical section on line 7 f of Fig. 6; and Fig. 8 is a vertical, side view of a fascine.

Referring now to the drawing for a more particulardescription, numeral 10 indicatesa silt-bearing stream with permanent, high banks 11, and temporary Banks 12 ;'and land areas, indicated at w, between these banks and known as bottom lands are usually subject to overflow, and therefore have but a limited value, comparatively. The bed 14 of streams of this class is usually of sand or light alluvial soil, and as is well known, it is readily moved'by the force of the current, and the depth of the channels of the streams are subject to frequent changes and sand bars are often formed so that navigation is not practical..- Also the temporary banks 12 are often eroded or partly re-- moved by changes of the water current and vast areas of bottom land m, between the main body of the stream and the permanent banks 11, are often submerged or removed by the changing current.

In order that deposits of silt maybe made upon the bottom land w,and erosion of the temporary banks 12 may be prevented, and to the end that the main water current may be confined in a permanent channel so that navigation will be practical, we provide barriers, levees or dikes 15 arranged opposite to each other inv pairs and parallel; they ma be formed of soil or other similar materia and may be reinforced with-piling p if desired, and each is disposed substantially at right angles to the stream and extends at a uniform" altitude from the permanent banks 11 to terminate in said stream, the terminals being provided with upright. standards, piers-or caissons 16 adapted to withstand the force of'a water current; The

barriers or dikes 15 and caissons or piers 16 have an equal height, substantially, and their upper surfaces are a suitable distance above high water mark b b. At the -lower part of Fig. 1 and in Fig. 5 a terminal air of levees or dikes are indicated at 15 or convenience of description. They are the same in all respects, however, at levees or dikes 15,

j The caissons or piers may be of any pre- 'ferred form or material and may consist of any "desired number of parts, and may be sunk to bed rock'18 or other permanenthard bottom by any referred means,'and they are disposed su stantially VGItlCflL, They may-be constructed to advantage of metallic sheets formed into sections 19, each havmg'a convexed front surface and,a concaved rear surface 21 to form a crescent-shaped casing, each section or casing having, at one of its ends, areduced part to form a flange 22. The sections, if formed in this manner, may be disposed one upon the other, the flange of each up er section being disposed 15 upon the inner s1 e ofthe nextlower section to provide the complete caissonor p1er 16, the hollow crescent-shaped sections being filled with cement or other heavy filling material. Before the piers' or caissons have been sunk, sand bars may be formed at the desired points as foundations for the parallel dikes or levees. These sand bars are preferably formed in the stream by use 'of the riprapping system described in Letters Patent to James M. Maher, No. 975,551, dated Nov. 15, 1910, or by an other suitable -means. The dikes are pre erably formed with fiat upper surfaces and upwardly-convergent side walls, and upon their sides may be supported, by flexible strands or cables 23 passing transversely through the dikes, the fascines 24; and fascines 24 may have bearing upon either or both sides of the dikes and may be used to substantially cover the sides of the dikes from the piers to the permanent banks of the stream, the function of the fascines, in this instance, being to revent disintegration or erosion of said dlkes from action of the water at times of an overflow of the areas m-of the land. Fascines 24 and other fascines hereinafter mentioned may be of any suitable construction, but, preferably, they consist of a plurality of slats 31, disposed side-by-side in a single plane, wire 32, or other strong, flexible material being used to secure the slats togither; and diagonal braces or Wires 33 may employed to maintain the frame, thus provided, in rectangular form, and, as shown in Fig. 8, the lower part of the fascines should be weighted at or near their bottoms, so that by operation of gravity, they will remain, normally, in an upright position, when suspended in a water current, as hereafter explained.

At 25 are indicated primary cables exfending between and secured to the piers or caissons at the same side of the stream, and upon these primary cables, at, lon itudinal .9 intervals thereof, and by any suitab e means, may be secured fascines 26; and secondary or cross-cables 27 may be employed, these being secured upon and at. longitudinal intervals of the primary cables at one of their 5 ends, their opposite ends being anchored at 28 in areas X of the-land, and-bearing, at

longitudinal intervals, fascines 29.

Posts or piling 30, referably of metal, may be driven in the ed of the stream at points'belowor down-stream from the terminal pair 15 of levees, for the support of one terminal of primary cables 25, their op-.

'osite ends being supported by the iers of evees 15', and secondary or cross-ca les 27' may be employed, these primary and crosscables bearing fascines indicated, respectively at 26' and 29', the arrangement of the cables and fascines last described being substantially the same an d for the same purposes as those mentioned in the preceding paragraph. By the arrangement of arts as described each fascine is disposed su stantially parallel with the cable by which it is supported, and the primary and secondary fascines are disposed at, substantially, r i ht angles to each other; and each pair ofikes or levees form, between their adjacent piers, a passageway g. This passageway may have any desired width, and there will be a tendency for the water to move; in a channel or ourrent directly from one passageway g to another. Silt carried" by the current will, of course, be moved down stream to points below each caisson or pier, and on accountof the usual formation of eddies the silt will be moved toward the shore, resulting in'the formation of sand bars upon areas b, said areas being between. fascines 26 and the temporary shore line 12, fascines 29 aiding in these formations or deposits. This is desirable, since it limits the width of the main channel. After sand bars have been. formed to fill areas k, the fasoines and cables remain buriedin the soil to thereafter prevent erosion. 7 During periods of high water, areas :0

and lt-may be covered with water, but fascines 24 tend to prevent erosion of the dikes,

and the operation of

fascines

26 and 29 will cause additional deposits to be formed upon these areas, and by reason of repeated over flows, said areas will be gradually covered With'soil to a-height substantially equal to the high water mark I) b, and these areas will therefore be reclaimed, and will be transformedto valuable land. As described,

a channel will be formed to include each of the pasageways g, and since the current will be confined to this channel, the carrying force of the water willcause a comparatively deep channel to be maintained, the

stream thereupon beingavailable and practical for purposes of navigation.

While we have shown the-pairs of levees v at substantially uniform distances apart, longitudinally of the stream, we do not limit ourselves to this feature, for the course and fall of the stream must be considered.

- While we have shown both primary and 1 secondary cables, with fascines, in many ingle levee, if maintained in a. position to extend partly across a silt-bearing stream substantially at right angles to the current,

would operate in a measure to control thecurrent and to cause deposits of silt at points down-stream therefrom, and would be especially effective for these purposes, if fascines are used and are supported as illustrated in thedrawings.

In addition to the advantages thus enumerated of the hereindescribecl system, it

maybe stated that the channel maintained will be of less length than formerly, this feature being of especial importance when distance for navigation is considered. Also fascines 26 and 29 during local storms and rains, tend to prevent the Wash of soil from the permanent banks into the stream.

Having fully described the several parts and their uses, a further explanation relating to operation is not required.
