JOHN G. BRUGGEMAN, 0F CLEVELAND, OHIO.
IMPROVEMENT IN BREAKWATERS.
Specification forming part of Letters Patent No. [75,270, dated March 28, 1876; application filed February 11, 1876.
To all whom it may concern Be it known that I, JOHN G. BRpGGEMAN, of Cleveland, in the county of Guyahoga and State of Ohio, have invented a new Method of Constructing Breakwaters, of which the following is a specification:
This invention relates to a method for constructing cribs for breakwaters, piers, and the like; and consists of walls constructed of boards or planks, cross-tied and braced in such a manner that it shall possess adequate strength, and be sufficiently tight to hold a sand filling.
The object being to lessen the cost of construction, as hereinafter fully shown.
In the accompanying drawing, Figure 1 is a perspective view of the said crib. Fig. 2 is a sectional view, showing the manner of constructin g the same. i
I take boards or planks of two or three inches in thickness, and eight to twelve inches in width, planed or dressed on one side, and first make a foundation-frame of two courses, A, Figs. 1 and 2, taking care in each and every course to break joints, each course of plank being spiked to the next below, using spike of sufficient length to reach through three thicknesses of planksr Upon the said frame A I next lay a floor of' plank, B, crosswise, over which I lay a second floor, G, in like manner, but breaking the joints as shown; then over this 1 lay a third floor, D, the planks lying lengthwise of the crib, and crosswise of the planks of the two first floors. Upon this bottom or base I lay the walls for the sides and ends of the crib, and at suitable intervals placing cross-pieces E between the side walls, and braces F F at the corners to give strength to the structure. The difierentlayers ,of plank composing the walls are arranged so as to break joints, and, being firmly spiked together, form tight walls, capable of holding and retaining a filling of sand or common earth.
This makes a substantial and durable breakwater, which may be built and towed to the Witnesses:
