JOHN B. CYR, OF SEATTLE, WASHINGTON.
SECTIONAL BREAKWATER.
Application filed April 2, 1918.
To all whom it may concern Be it known that 1, JOHN B. CYR, a citizen of the United States, and resident of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Sectional Breakwaters; and the following is a clear and exact specification of the same.
This invention relates to improvements in sea wall or break-water construction, and the object of this improvement is to provide a sea wa ll or break-water of this class that may be built in sections which may be floated to the location where the sea wall is to be built, and then sunk by filling them with heavy material as sand or gravel.
A further object is to provide a device of this nature that is strong and durable in construction and that will last for a long period of time.
A still further object is to provide wall sections composed of cribs that are mounted on platforms constructed of rough logs thatare of larger size than the cribs whereby they form a broad footing and a bottom for the cribs and prevent the water from undermining the cribs.
The invention consists in the novel construction of a sectional break-water and in the novel construction of the cribs of which such break-water is formed as will be more clearly hereinafter described and claimed.
In the accompanying drawings Figure 1 is a view in perspective of one section of a breakwater constructed in accordance with this invention. Fig. 2 is a plan view of the same. Fig. 3 is a view in vertical cross section substantially on broken line 3-3 of Fig. 2 and Fig. 4L is a somewhat diagrammatic plan view on a reduced scale showing a plurality of sections secured together to form a break-water.
Referring to the drawings throughout which like reference numerals indicate like parts, the numeral 5 indicates a base or platform that is preferably constructed of rough logs or timbers 6 disposed side by side in parallel relation crosswise of theplatform and secured together at both ends by means of longitudinally extending logs 7 that are bolted thereto by bolts 8.
Extending lengthwise of the platform 5 and centrally arranged thereon is a crib, preferably of rectangular shape and formed of side walls 10 and end Walls 11. The crib may be constructed of squared timbers of Specification of Letters Patent.
Patented Dec. 17, 1918.
Serial No. 226,149.
large size and the timbers that form the end walls may be mortised into the timbers that form the side walls in a well known manner which is indicated in Fig. 1.
The side walls of the crib which extend lengthwise of the raft or platform 5 and crosswise of the logs that form the plat form are secured to the logs 6 by long bolts or rods 12 that extend downwardly through the sides of the crib and through the logs and are rigidly secured thereto by nuts 13.
For the purpose of bracing the crib structure and securing it more firmly to the platform 5, I have provided a plurality of oppositely disposed angular brace rods let that are secured to the longitudinally extending logs 7 by bolts 15 and are each connected with each other and with the crib by transversely disposed bolts or rods 16 that extend crosswise of the crib as more clearly shown in Fig. 3 and are rigidly secured to the crib and to the rods 14 and nuts 17.
Disposed within each of the 4. corners of the crib are upright posts 18 that are bolted or otherwise rigidly secured to the timbers of which the crib is formed and that may be used as anchor posts around which cables 19 may be tied to secure adjacent sections of the crib together in end to end relation, as more clearly shown in Fig. 4. The posts 18 may also serve as anchor posts for vessels that are lying alongside of the breakwater. i
The crib when thus constructed is rigid with the platform 5 and is adapted to withstand a heavy pressure of the water from either side.
In forming a breakwater or jetty the cribs, which are sufiiciently buoyant to float, are towed to the location where the breakwater or jetty is to be constructed and are then sunk in their proper position by filling them with sand or gravel as indicated by the numeral 20 in Fig. 3. A plurality of the cribs are thus sunk in end to end relation as illustrated in Fig. 4: and are tied together by the cables 19 so that they will form a continuous breakwater.
The crib is preferably filled with sand and gravel up to a point near the top, a layer of brush is indicated by the numeral 21 in Fig. 3, is then placed on the top of the sand and gravel and large heavy stones as indicated by the numeral 22 are then placed on the brush, the stones 22 being piled up even with, or above, the top of the. crib and being large enough and heavy enough so that they are not displaced by the wash of the water if the waves wash over the crib.
After the cribs have been sunk in their proper end to end relation and anchored together as shown in Fig. & the space between the end walls of two adjacent cribs, desig nated by the numeral 23, may be filled with gravel and stone in the same manner as the space within the cribs.
The platform 5 is preferably constructed of heavy rough logs that are substantially round in cross section and form a corrugated upper surface that tends to catch the sand that washes over it.
When the breakwater sections are sunk into place the platform 5 will rest on the bottom of the river or bay in which the wall is located and will become partially embedded in the sand as shown in the Fig. 3, so that a rigid support for the crib will be formed.
The portions of the platform 5 that project outwardly from the sides of the crib serve as a footing that prevents the water that strikes against the sides of the crib from washing out a hole at the bottom of the crib and undermining the same.
t will be understood that this form of breakwater sections may be used in the construction of harbor and river jetties or piers in practically any location where such jetties or piers are required and that it may be used for various other similar purposes as for building bulkheads and groynes to prevent the Washing away of shores by flowing streams.
Where the breakwater sections are to be used in salt water as in ocean harbors the timber that enters into their construction will preferably first be treated in some well known manner as with creosote and alum to prevent rapid deterioration of the timber and to render it impervious to teredos.
It is obvious that changes in the precise form of construction of the structure herein shown and described may be resorted to' within the scope of the appended claim.
lVhat I claim and desire to protect by Letters Patent is A structure of the class described comprising a platform constructed of transversely arranged rough logs, a crib of substantially the same length and of less width than said platform secured lengthwise thereof, truss rods extending crosswise of said crib and rigidly secured thereto, angularly arranged brace rods connected with the ends of said truss rods and with the outer edges of said platform for bracing said crib, and anchor posts rigidly secured within the four corners of said crib and projecting above the top of said crib.
Signed at Seattle, Washington, this 7th day of March, 1918.
