HENRY F. KIEIIJIJNEB, 0F SILYEB LAKE, KANSAS.

To all whom it may concern:

Be it known that I, Harm: Knnnmm, a citizen of the' United States residing at Silver Lake, in the county of Stateof Kansas, have invented'certain new and useful'lmprovements in Jetty Construction, of which the following is a specifics tion. I

This invention relates to an improvement in jetty construction, and has for one of its objects to; rovideself sinking, angular frames or de 'ectors of such construction that hey will,=engage...:the..bed of a water channel to advantage and will not be readily overturned -by-awater current. The invention also'relates to deflectors so constructed that strands, when connected to opposed parts thereof will 0 crate to advanta e in maintaining the' de ectors substantial y in line. 'Thef'inventiom also has reference to simplicit' and durability of parts 'so-that' practical, convenient The novel features of the inventiofiare fully describedihereinand are pointed out in t e appended claims, and are illustrated in the accompanying drawing, wherein,'

Figure 1- is a perspectivevie'v of one of the angle irons employed. Fig. 2 is a perspective view, illustrating a plurality of angular frames'or current deflectors maintained in linein a silt-bearing stream. Fig.

3 is a side or end view of a current deflector, the strands being omitted, Fig. 4 is a side or end view of a current-deflector provided with cable "or strands. V

I provi e a plurality of angular frames or current deflectors 5, each consisting -of stri s orbars of angle irons, substantially of uni orm length, as the strips-""6, 7 an 8 *-1,.having one of'its flanges provided Wi semhled w apertures9,its other flange being-provided with a ertures 10, said apertures 9 and 10 "being isposed midway between the ends of the strip, each "stripalso being providednear its respective ends with apertures 11 formed ineach flange.

By use of the strips thus described an angular f ame" may be conveniently asifch, when placed in swiftly moving water I overturned, since it will provide three prongs, as will be seen, which will engage the bed) of the channel, each flange of an angle iron being in engagement witha flange Specification of Letters Patent.

of an adjacent angle-iron strip, rivets or equivalent keepers 12 being employed and Patented Oct. 8,'1918.-

traversin the apertures 9 and -10, and thereby pro'vi mg a connection for the strips midway'between their ends, each end of each stri being connected with an end of each of t e remaining strips by means of strands 13, whereby stresses directed to the outwardly pro eCting prongs or end portions of the strips will be adequately resisted.

Means are provided for maintaining the angular frames thus provided in connected relation when placed in a stream or water channel, as the strand 14, which is secured to each frame at its middle, and 'which'is secured to an anchor-post 15 upon the bank,

as shown in Fig. 2.

Also means are provided for preventing inversionof the deflectors or frames, consisting of the strands 16 and 17 these being secured, respectively, to the two adjacent upper ends of two of flector, the strand 16 being secured to an anchor-postl8 on said bank and the strand 17 being secured to the anchor-post 19 on the bank. It will be understood that if the posts 18 and '19 are spaced apart transversely of the line of the deflectors, as shown in the drawing, this arrangement will tend t'he-strips of each deto prevent inversion of the frames, and on account of their form and Wei ht, .the

frames will so engagethe bottom where the water moves very swiftp'andin such instances additional anchorage (not shown) may be provided.

The construction thus described is'of advantage in the formation of all-uvia de posits in silt bearing streams. Since-all of" the parts areconstructed of iron, the frames will readily sink, and on account of the peculiar form the force of moving "water, the outwardly divergent prongs normally engaging the bed of a stream regardless of the position of the frames. i l

In operation, several of the frames may be connected and, secured "to the bank 20 of a stream2l, the straight or curved lineof the connected frames water carrying silt or sand and moving the direction indicated by the arrow shown in Fig. 2, will causeal 5 being transverse to the-liowing water and disposed at any desired angle with reference thereto 5 and 110 o a channel that they will maintained in line transversely thereof except in instances for the frames they will resist uvial deposits 22 i below or down stream from the deflectors or frames 5, the object, in some instances, being 'toprevent the water from cutting away the land or banks of a stream; also to change the direction of water currents, and also to cause accumulation of land at a water front. In the for1nation-of jetties in tide waters the frames, when connected, are disposed transverse to the flow of the tides, the result being that sand bars will form at each side of the line of the connected frames, and since the frames are ,durable and on account of their form, they tend to maintain the sand-bars as permanent supports for a roadway or for piers or wharves.

Having fully described my invention,- what I claim and desire to secure by Letters Patent is,-

1. In jetty construction, a pluralit of current defiectois disposed substantial y in line in a water current, each consisting of a pair of bars of angle iron disposed at right angles and connected midway between their ends and a third bar of angle iron disposed at right angles to each barof the first pair of bars ofan le iron and connected therewith midway etween its ends. 2. In jetty. construction, .a plurality of" current deflectors disposed substantially in -line in a water current, each'consist-ing of a trinity of apertured angle-iron strips subother two strips, rivets traversing the apertures of theengaging flanges and met-Quie strands connecting the terniinals of each strip with the terminals of the remainin in strips. 3. In 'jettyconstruction, a plurality of current deflectors each consisting of a pair of strips of angle iron disposed substantially at right angles and engaging each other 1nidway between their ends, at-hirdstrip of angle iron disposed at Substantially right connected therewith-"midway between its ends, strands connecting the ends of each strip 'with the ends. of the other strips of angle iron, a cable connected with a strip of. each deflector; a second cable connected with a stri of each deflectorg said cables being secure to a stationarysupport for maintaming the deflectors in line in a Water current. v
