Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
129 words
A separation device for separating a down flowing stream of water containing debris, such as leaves, comprising in combination: a. a path for water generally downwardly through the separator, b. a grating interposed in said path, said grating comprising a plurality of roughly parallel bars, said bars being set at an acute angle of less than 30° to the vertical whereby water passing downwardly through said separator flows through said bars and debris contained in said water will be caught by said bars and separated from said downflowing stream of water and whereby said debris is caried downwardly along said grating and exteriorly of the separator through an opening in the separator, and c. the lower terminal end of each of said bars being bent to be substantially vertical.
Claim 2
Dependent Claim
