ABSTRACT:
An elongated, conical cage of spaced-apart rods is disclosed, each rod having a first and secured to the apex of the cone, and a second end terminating in the open of the cone which is formed by a circular ring-shaped rod. The open end of the conical cage and the circular rod forming the open end are secured to a band preferably constructed of metal which forms a fixation device for securement to the exposed end of the pipe. Preferably, the rods forming the conical cage are spaced apart by approximately six inches, a distance which has been found sufficiently wide to enable debris to flow through and out of the apparatus, and sufficiently narrow to prevent entry of small animals such as beavers into the apparatus. The elongated concial cage of rods forming part of the present invention is preferably constructed approximately six feet long, a distance which has been found sufficiently long to enable large twigs, branches, and other debris flow smoothly out of the device without becoming jammed within it or against the interior of the apex of the conical cage. The position of the rods will cause the sticks which block the pipes to turn inward under pressure of water flow and thus permit passage of the sticks and refuse thorugh the pipe. The device thus allows an unrestricted flow of water through outdoor drainage piping by preventing debris, trash and animals such as beavers from stopping up the pipes.
