BEACH-RECLAMATION SYSTEM.

Application filed February 4, 1924. Serial No. 690,377.

To all whom it may concern Be it known that I, LEWIs. M. HAUrT, a

, citizen of the United States, residing in Gynwyu, county of Montgomery, State of Pennsylvania, have invented a new and useful Beach-Reclamation System, of which the following is a specification. My invention relates to a beach reclama- 1 tion and protection system or work, and has to relation to the system described in my Letters-Patent No. 1,010,139, dated November 28, 1911. i As in the case of that invention, the general purpose of the present invention is to control and direct the natural forces of 5 wind, wave, current and tide in such manner that they will accomplish the useful ends of protection and reclamation, instead of destruction. i V v Specifically, the objects of the present invention are to increase greatly the efficiency of the work referred to, especially for the re covery and restoration of beaches which have been carried away, whether by gradual and continuous tidal and wave action; or

suddenly, by violent storms; and to accomplish this result at a cost materially less, both for construction and maintenance, than is obtained by the usual'bulkheads supplemented by spur-jetties or groins. The principal features of the present invention are the combination with the wave decomposing jetties (such as are described in myformer patent) of an impounding basin or basins, adjacent to the shore-end thereof which serve to decompose the attacking maritime forces, and render them inert from harm and to form impounding sandy barriers or reservoirs at their bases, especially where aubtments are necessary to 40 avoidya flanking movement, and toprotect the .reentrant angle caused by bulk-heads andthe normal spur. vjetties, thus affording rotection to life andproperty and increasmg the durability of the structures. By the means indicated, and hereindescribed, later,

in detail, the winds are caused to cooperate with the waves, in reinforcing the strand and reclaiming a more permanent beach, automatically. 7 The 1nvent1on conslsts of the novel construction hereinafter described and finally claimed. l j

The nature, characteristic features an scope of the invention will be more fullyun derstood from the following description taken in connection with the accompanying drawings forming part hereof, and in which:

Fig. 1, is a view of a reclamation jetty with its supplementary devices for the decomposition of the erosive forces and their conversion into constructive elements, by precipitating the sand or shingle within the retaining enclosures, thus building dunes.

Fig. 2, is a detailed viewindicating the character of the structure and the means employed to render it relatively permanent by connecting it with the strand to be protected, instead of laying it on the surface of the ground, to be swept off by storms.

For the purpose of illustrating my invention I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice togive satisfactory and reliable results, althoughit is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized-and that my invention is not limited to the precise a'r rangement and organization of the instru- 30 mentalities as herein shown and described, but can. be adapted to local physical conditions. r

The function of the reclamation jetty portion is to retard and decompose the 0E shore forces and to direct them obliquely up the beach without at the same time arresting the drift entirely on the windward side, and robbing the leeward sector; while the purpose of the impounding reservoirs in the 9 groins, is to create, incombination with the reclamation jetty, as a feeder, a trap to receive and store the driftthus driven up by the sea, and to protect the hinterland from overflow by storm tides, which destroy, or impair the use of highways, roads, or dwellings. V I

Referring. to the drawings specifically, there is shown in Fig. 1, a typical reaction jetty in combination with the buffers 1, comentrances 4 at both ends which are con-tract ed so that the waves are broken and the segments entering the curved fl'anks made to:

meet inside in the broader sections and by opposition check the advance and prec1p1- tater their sediment, thus constituting a set,-

tling basin 2 and wave breaker at small cost,

and rapidly protecting the jetty and the adjacent property from loss. The buffers l arebraced; by strips of timber 6.

In Fig. 2, there is shown the character of the construction and the general method of bracing consisting of piles 5', having the proper: penetrationthus anchoring them to the subsoil and! bracing them, as at 6", so rigidly as to prevent vibration from the most violent storms, and causing the structure to deposit and hold the drift so that in many cases it becomes buried under the deposits which, it creates and thus becomes permanent. The bracing 65 consists of crisscross struts arranged, between adjacent lines ofpiles 5.

No claim is made however for connecting the structure with the foundation, which is the usual method, but merely the adjustment of'the cooperative devices for the retention and rapid upbuildingiof these additional factors to increase efiiciency and permanency while reducing cost by thev omission of rock and brush filling, so generally required in-t'his class of structures.

In carrying out my invention, I dispense,

therefore, with all dikes, sea-walls, spurs.

groins and similar structures of earth, stone, Wood, or other materials singly or in combination. 'The only n'laterial required is wood in the form of piles 5'- and bracing 6, (not as in that of cribs or caissons,) With the necessary bolts, spikes, stringers and batter-piles and other attaching devices to maintain the rigidity of the structure, which is not designed to be water-tight, but on the contrary to be sufficiently permeable and non-resistant so as. to permit said to pass freely through, while higl'i'enougli to check the Waves of' ordinary storm-tides.

Thus economy in first cost as well as economy in maintenance is effected; the efficiency of the system is readily increased by the more rapid accumulation of sand impounded in situ; and eventually is reduced to little or nothing for maintenance, when the structure is buried under the sand which. it has impounded" on both flanks and beyond its extremitv.

cavely: arranged with respect to advancin The lengths, grades, radii, and locationas well as the degrees of curvatures of its several elements may vary within Wide limits, depending upon the local physical conditions and the exposures to the attacking forces of the seas.

An additional? factor in the protection and reclamation of alluvial beaches is that g ofpermeability, for in practice it is customary to build them, tight, whether of stone or wood, to prevent the waves from passing tliroughand: to! arrest the sediment they may carry and retain it in the windward groin, thus robbing the- Ice, and converting the jetty into a hurdle, causing the surge to, roll over and. denude the opposite flank, with injury to abutting properties; V 1 This, may readily be revent'ed bydispensing with the rock an brush filling, or the use of tight sheathing piles, and by placing only the barrier piles, whether in one or two rows, as may be required, inxjuxtaposition as shown in Fig 2,, so that; the surcharged waves may be checked, in. part, yet pass through and, deposit their sediment equally in both. flanks or groins, and, thus not destroy the continuityof the surface of the beach, while at the sametime, the cost is reducedand" the efii'ciency nearly doubled, as the number of such jetties will be re duced somefifty per cent ormo're, iii-addition to the saving in the cost' of construction.

I It will now be apparent that I have devised a, novel and useful combination which i embodies the features of advantage "enu merated as desirable in the statement of the invention and the above description and wl'ii-l'e I have inthe present instance shown and described the preferred embodiment thereof which has been found. in practice to give satisfactory and reliable; results, it is to be understood that the same is susceptible of modification in; various particulars without departing from the spirit or; scope of the invention or sacrificing any of its advantages.
