Abstract: An implement for cutting grass or weeds or the like wherein a Weedeater type cutting head is provided on which a cutting line or blade or the like cutting element is mounted for rapid whirling motion, wherein protective shielding is provided on the implement and interposed between the cutting element and the normal position of the operator, and a skirt-like mat of tough, resilient, flexible plastic filaments are provided on the implement for extending downwardly toward and preferably into contact with a terrain surface when the implement is in its operative posture, the filaments being sufficiently flexible to readily conform to the terrain surface when brought into contact therewith to thereby afford greatly enhanced protection against flying debris while providing substantially unhindered freedom of motion to the cutting head.

Abstract: An apparatus for plugging the interior of a pipe that is penetrated by an axis opening including an upright tubular plugger housing attachable at its lower end to have communication with the interior of the pipe through the opening. An elongated vertical cylindrical control bar is provided with a plugger at its lower end, the plugger being positioned through the opening into the interior of the pipe to close against further flow of fluid through the pipe. A jack is affixed to the plugger housing upper end and telescopically receives the control bar, the jack being pivotally affixed to the housing so that the control bar, having a plugger on the lower end thereof, can be pivoted relative to the housing and thereby relative to the pipe for proper positioning of the plugger in the pipe.
