Abstract
Abstract A tubular attachment for portable air blowers to allow the cleaning of rain gutters and the like, wherein flowing air is conducted from the blower upwardly to approximately the height of the gutter, turned horizontally to pass over the gutter lip and then turned downwardly into the gutter trough to blow out leaves, twigs and other debris. The blown air is directed into the gutter through an adjustable elbow arrangement in which a terminal section of the elbow is rotatable with respect to an inner section of the elbow to allow the angle of air flow to be varied, so that cleaning may be accomplished from left-to-right or right-to-left along the gutter.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
164 words
For use with a hand-held air blower, an attachment for cleaning out leaves, twigs and other debris from the trough of a rain gutter, comprising: an extension for conducting the air flow from the air blower to approximately the height of the gutter; an elbow to direct the air flow from said extension into the trough, said elbow including an inner section attached to said extension to conduct the air flow over the lip of the gutter, a terminal section to receive the air flow from said inner section and direct the air flow into the trough, and a joint allowing rotation between said inner section and said terminal section about an axis lying generally horizontal with respect to the ground, whereby the operator of the air blower may selectively direct the air flow to the left or to the right and set the downward inclination of the air flow into the trough by rotating the terminal section with respect to the inner section.
Claim 2
Dependent Claim
164 words
For use with a hand-held air blower, an attachment for cleaning out leaves, twigs and other debris from the trough of a rain gutter, comprising: an extension for conducting the air flow from the air blower to approximately the height of the gutter; an elbow to direct the air flow from said extension into the trough, said elbow including an inner section attached to said extension to conduct the air flow over the lip of the gutter, a terminal section to receive the air flow from said inner section and direct the air flow into the trough, and a joint allowing rotation between said inner section and said terminal section about an axis lying generally horizontal with respect to the ground, whereby the operator of the air blower may selectively direct the air flow to the left or to the right and set the downward inclination of the air flow into the trough by rotating the terminal section with respect to the inner section.
Claim 3
Dependent Claim
38 words
The apparatus of claim 1, wherein said terminal section is curved to deflect the air flow through about 90 degrees, and said inner section is curved to deflect the air flow through about 75 to about 85 degrees.
Claim 4
Dependent Claim
177 words
An improved attachment to a hand held air blower for cleaning out leaves, twigs and other debris from the trough of a rain gutter, said attachment having an extension for conducting the air flow from the air blower to approximately the height of the gutter and an elbow for directing the air flow from the extension into the trough, the improvement comprising: a joint in said elbow, said joint dividing the elbow into an inner section attached to the extension to conduct the air flow over the lip of the gutter and a terminal section to receive the air from the inner section and direct the air flow into the trough, said joint allowing rotation between the inner section and the terminal section about an axis lying generally horizontal with respect to the ground, whereby the operator of the air blower may selectively direct the air flow to the left or to the right and set the downward inclination of the air flow into the trough by rotating the terminal section with respect to the inner section.
Claim 5
Dependent Claim
