OCEAN PIER;

Patented July .25, 192.2

Application lcd February 10, 1920. Seria1.No.v357,6S1.

To all wlw/m tmay concern:

Be it known that I, ALLAN CYRUs RUsH, aL citizen ofthe United States, residing at 1636 McCullom Street, Los Angeles, in the county of LosAngelesand State of California, have invented a new land useful Improvement in Ocean Piers, of which-the following is a speciiication.

lThis invention is more particularly intended for piers subjected to ocean wave action, but it is understood that it ymay be employed wherever desired. y

An object ofthe invention is to provide practical means for extending land for the landings of vessels, pleasure resorts or warehouses into the ocean or other bodies of water and to insure against the` destruction of` the'same by wave action, and also to provide against iiooding or spraying the surface of the land, promenade, roadway or the like by high seas or other wave action.

The invention comprises a wave resisting structure of an elongate horse shoe form. The arch of the horseshoe being seaward and the terminals of the horse shoe landwardand extending indefinitely parallel to each other as occasion may demand, and spaced fronithe land or connected-thereby directly or by any suitable means,psuch as draw,

bascule or stationary bridges.

A feature of the invention consists in a new and useful form imposed upony the upper portion of the structure and consists in' a wave deflecting bead or ledge arranged above normal high water level and surmounted by a guard extending above the deflecting bead a sufHcient distance to intercept'the ksplash and sloppings from the waves.

Another feature of the invention is the use of a shorter pile driven in between any four adjacent piles, toI increase the. solidity ,of the sub-foundation, and also serves as an additional anchor for the concrete matrix above.

Other objects, advantages andI features of invention may appear from the accompany-.

ing drawings, the subjoined detailed description and the appended claims.

The accompanying drawings illustrate the invention.

Figure l is a perspective view of a, pier constructed in accordance with this invenpartly exposed for section of one of the driven, intosuch bottom, and by means of Colfer-dams, not shown, the heavy structure of` the pier will be constructed ou thesub foundation' thus formed with such bottom und piles.

In such case thepiling will first be driven into the soft bottom and will then be cut 0H to leave the tops thereof a desirable distance, say five or more feet below the normal level of the ocean Hoor. Then a concrete or other suitable superfoundation rwill be imposed upon the sub foundation formed by said piles and the earth into which they have been driven.

In practicethe concrete may extend below the tops of the piles so that the concrete forms a matrix which is embedded inthe earth and in which matrix the tops ofthe piles are embedded and held in place.

The superfoundation Q laid may be of any suitable thickness, sa f two to sixpfeet, more; or less, and will preferably be in the form of the frustum of a triangle, the apex a of which would terminate approximately at the level of the surface 3 ofthe pier when completed.

When the concrete foundation or bed has thus been completed, its top surface should be somewhat below thenormal level of the oceaniioor Thezbottom of the concrete super base thus formed may in the instance illustrated, be considered to be about five feet below the normal level of the ocean floor. Upon this concrete bed, courses CZ of granite or other substantial stone is well constructed, and in the form shown, the same is built of blocks 4 of granite hewn to form and secured of concrete thus f o ether by dowel pins 5 and concrete mor- .a 6; and said'stonev is laid with broken `oints and the individual stones are of as large dimensions as available and convenient.

The granite or other heavy stone structure will extend as a facing 7, toward the wave receiving side at the arch and along both legs 9 and will extend a requisite distance toward the inner Ytace of the pier.

ln practice it is deemed advisable to eX- tend said cut stone work well in beyond the central plane of the stone structure and against the inner 'faces oi such structure there may be formed a backing l0 of broken stone or any suitable material.

rlhe exterior face at about eight feet above normal high water level c is formed as a ridge or bead ll and the surface 12 of the structure below the ridge is an ogee, tangent to the upward inward slope oi the base. Above said ridge the surface is formed with a substantially upright `tace 13 extending 'from the horizontal surface 3 of the structure, downward to the formation ot a smaller ogee tangent tothe inward slope of the upper face of said ridge or bead.

The piles l are spaced apart a distance oit eight 'teet more or less in each direction; and where it is deemed advisable, an extra, shorter pile may be driven in the center between any four adja'centpiles, to render its own service and to brace the other piles by crowding the sand tighter against them.

During the building or after the structure has been completed, the space confined by the arch and legs or' the structure'and such Cotter-dams as may be required at the terminals, will be filled with land forming material such as sand or other loose material which may be pumped from the ocean bed to deepen the channels outside the pier or Yfrom the main land. Such material may be pumped from any practical distance either from the ocean bed or the shore until, when the pier is completed, an internal vfilling lei will have been made entirely 'within the stone structure. Said stone structure may have. a. width at the surface ot about 25 .feet more or less for a pier of 600 feet in width.

It is deemed advisable to construct the pier of such length as to provide a site for pleasure grounds or ttor commercial manufacturing or other purposes and tor the landing ot vessels.

The piles are preferably arranged quincuncially as shown in Fig. a and one of each live piles may be shorter than the otherfour piles and may be driven centrally or the quincunx so as to be alined in two directions with other piles. ln Fig. 5 the shorter piles l are driven between longer pilesA l after the longer. piles have been driven. The purpose of this is to 'form a iii-nier and more solid and substantial bottom upon which the concrete 'foundation 2 may be laid, This is done by crowding said shorter piles into the ocean floor between'the previously driven long piles.

fitter the soit bottom has been removed and the upper ends ot the piles cut oil 'to a somewhat common level. the great mass 2 oi? concrete is poured upon said piles and the solid and moist ocean bed and becomes integral with same.

Any sand which may have been loosened at the surface, especially around the piles by operations or other causes will be compressed and held tast as it is enveloped by the great body of concrete which is established upon it.

I claim.

l. A pier wall having an outer ilace provided with a bead, said Jface 'sloping 'from its base upward and inward toward the bead and trom the ridge of the bead downward to said upwardly and inwardly slopingface, the upper tace ot the bead sloping upwardly and inwardly and a guard extending outwardly to intercept the splash and slosh.

2. A pier wall having an outer tace pro` vided with a bead, said Yface sloping Vfrom its base upward and inward toward the bead and from the ridge ot the bead downward to said upwardly and inwardly sloping lace. the upper tace of' the bead sloping upwardly and inwardly and a guard extending upward to intercept the splash and slosh, the iace ot the guard overhanging outwardly.

3. A pier wall having an outer tace provided with a plurality o'll beads the outer surfaces ot which extend upwardly iu an inwardly and outwardly direction, one ol said beads acting as a wave dellecting bead, and another olf' said beads acting a guard to intercept the splash and sloppings trom said wave detlecting bead. y

el. A. pier wall having an outer tace pro'- vided with a pluralityot beads, aud an ogee surface below said beads. l

In testimony whereof. l have hereunto my hand at Los Angeles, California. this 20th day of January, i920.
