ABSTRACT:
In summary, this invention is a rain gutter debris removal system, including a rain gutter and a debris removal device operable within the gutter. The gutter includes a back wall and a bottom channel member. The debris removal device includes an upright scavenging blade mounted within and lengthwise of the channel for movement between a home position retracted against the back wall, and an extended forward position across the channel. An actuator moves the scavenging blade between home and extended positions, whereby to expel debris from the channel. The scavenging blade includes a wiper blade along its bottom for wiping engagement with the gutter channel. The actuator includes a reciprocable expansible chamber device positioned between the back wall and the scavenging blade, and connected to the back wall for pivotal movement up and down, the wiper blade thereby maintaining wiping engagement with the gutter channel as the blade traverses the channel. A system having a number of these devices will include remote control to selectively operate the several devices.
