Abstract
Abstract A rainwater ducting system mounted adjacent the eaves of a building is comprised of a horizontally disposed open gutter containing horizontally directed auger means and a communicating downspout containing vertically directed auger means. The auger means are designed to occlude less than 50% of the cross sectional area of the trough and downspout, and are separately activated by waterproof motors remotely controlled and adapted to provide variable forward and reverse speeds. In operation, the auger means advance solid debris toward and downward through said downspout.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
205 words
A rainwater ducting system for use adjacent the eaves of a building comprising: (a) a horizontally disposed open gutter trough located beneath the terminal edge of a roof of said building in a manner to receive rainwater therefrom, horizontally directed auger means positioned within said trough adapted for rotative movement therein without contact with the inside walls of said trough, a first electric motor supported by said trough and operatively coupled to said auger means, and (b) a vertically disposed tubular downspout communicating with said trough adjacent at least one end thereof, vertically directed auger means positioned within said downspout depending from attachment with a second electric motor mounted atop said trough and positioned directly above said downspout, (c) said horizontally directed and vertically directed auger means each occupying less than 50% of the cross-sectional areas of said trough and downspout respectively, (d) said first and second motors being of waterproof design and capable of variable forward and reverse speeds, and (e) electrical control means for said motors located within said building remote from said trough and downspout, (f) whereby activation of said motors causes the associated auger means to advance solid debris along said gutter to said downspout and thence downwardly through said downspout.
Claim 2
Dependent Claim
205 words
A rainwater ducting system for use adjacent the eaves of a building comprising: (a) a horizontally disposed open gutter trough located beneath the terminal edge of a roof of said building in a manner to receive rainwater therefrom, horizontally directed auger means positioned within said trough adapted for rotative movement therein without contact with the inside walls of said trough, a first electric motor supported by said trough and operatively coupled to said auger means, and (b) a vertically disposed tubular downspout communicating with said trough adjacent at least one end thereof, vertically directed auger means positioned within said downspout depending from attachment with a second electric motor mounted atop said trough and positioned directly above said downspout, (c) said horizontally directed and vertically directed auger means each occupying less than 50% of the cross-sectional areas of said trough and downspout respectively, (d) said first and second motors being of waterproof design and capable of variable forward and reverse speeds, and (e) electrical control means for said motors located within said building remote from said trough and downspout, (f) whereby activation of said motors causes the associated auger means to advance solid debris along said gutter to said downspout and thence downwardly through said downspout.
Claim 3
Dependent Claim
23 words
The rainwater ducting system of claim 1 wherein said horizontally directed and vertically directed auger means have the configuration of a ribbon helix.
Claim 4
Dependent Claim
28 words
The rainwater ducting system of claim 1 wherein said control means comprises an on-off switch, a rheostat, and means for reversing the direction of operation of said motors.
Claim 5
Dependent Claim
25 words
The rainwater ducting system of claim 1 wherein said vertically directed auger means extends downwardly within said downspout for at least 1/3 the height thereof.
Claim 6
Dependent Claim
23 words
The rainwater ducting system of claim 1 wherein the axes of said auger means are coaxially coupled to the shafts of said motors.
Claim 7
Dependent Claim
37 words
The rainwater ducting system of claim 1 wherein the axis of said horizontally directed auger means is disposed at a right angle with respect to the shaft of said first motor, and coupled therewith by gear means.
Claim 8
Dependent Claim
17 words
The rainwater ducting system of claim 6 wherein said gear means are contained within a protective enclosure.
