Abstract
Abstract A barrier for water carried pollutants comprises a series of end to end connectable boom sections containing a flotable material; fluid impervious connectors for the ends of the boom sections; flexible draft members and associated connectors for maintaining the integrity of the boom if it becomes necessary to replace one or more of the boom sections, and means associated with the flexible draft members and the fluid impervious connectors whereby separating stresses are minimized at the end connections of the boom sections.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
240 words
A barrier for containing and controlling water carried pollutants comprising a series of boom sections, each boom section comprising a generally tubular portion and a skirt portion, each of the tubular portions containing a flotation material, and means connecting the boom sections in end to end relationship characterized by generally liquid impervious connectors for the ends of the boom sections; a first vertical flap extending along one edge of one end of the skirt portion and the tubular portion of each boom section; a pair of flaps extending along the other edge of the opposite end of the skirt portion and the tubular portion of each boom section; said pair of flaps arranged to receive said first flap therebetween; separable connectors maintaining the first flap between said pair of flaps; a pair of rigid metallic plates at each end of each boom section; each said pair of plates being secured together on opposite sides of the skirt immediately below the tubular portion; each plate of each pair of plates having secured thereto a pair aligned eyes; a flexible draft member extending along each side of each boom section just below the tubular portion; each flexible draft member having an eye formed at each end; a double ended shackle detachable connecting adjacent eyes of each flexible draft member, and means cooperating with the flexible draft members and the aligned eyes of each plate connecting the flexible draft members to said plates.

Claim 3
Dependent Claim
37 words
The invention defined in claim 1 further including a ballist chain along the bottom edge of each skirt of each each boom section and link means connect the ends of the ballist chain of adjacent boom sections.
Claim 4
Dependent Claim
37 words
The invention defined in claim 2 wherein the pairs of plates are separately connectable to the boom skirts so that said plates, cables are ballist chains may be simply removed for reuse on a new boom fabric.
