Abstract
Abstract A self-cleaning gutter system formed from two, horizontal, longitudinal halves interlocked along the gutter bottom longitudinal axis. The back half, immediately adjacent to the house or building is fixedly attached thereto. At either end of the gutter a piece transverse to the gutter's longitudinal axis protrudes from the ends of the gutter half fixedly attached to the house or building. A rod is positioned within the gutter along the gutter's longitudinal axis protruding at either end of the gutter through the transverse piece. The front half of the gutter has arms extending therefrom which are journaled to the rod. A gearing system attached to said protruding end engages an actuator shaft which extends vertically to ground level. The ground end of the vertical shaft is journaled to a simple geared handle. The operation of the handle will cause the front half of the gutter to open 180°, thereby dumping debris, ice and snow to the ground.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
147 words
A self-cleaning gutter system for a house or building which may be easily cleaned of debris remotely, comprising: a horizontal gutter formed from two longitudinal halves, a front half and a back half, wherein said two halves are interlocked along the gutter bottom longitudinal axis; a rod positioned within the gutter along the gutter's longitudinal axis between said halves, above said gutter bottom; a plurality of bracket assemblies interconnecting said gutter halves and engaging said rod, whereby said assemblies open and close as said rod is axially rotated in one direction or another; and an actuator shaft gearingly engaged at one end with a protruding end of said rod and extending vertically downward near to ground level, and having means by which the shaft may be rotated about its radial axis, whereby radial twisting of the actuator shaft causes said rod to turn on its radial axis.
Claim 2
Dependent Claim
147 words
A self-cleaning gutter system for a house or building which may be easily cleaned of debris remotely, comprising: a horizontal gutter formed from two longitudinal halves, a front half and a back half, wherein said two halves are interlocked along the gutter bottom longitudinal axis; a rod positioned within the gutter along the gutter's longitudinal axis between said halves, above said gutter bottom; a plurality of bracket assemblies interconnecting said gutter halves and engaging said rod, whereby said assemblies open and close as said rod is axially rotated in one direction or another; and an actuator shaft gearingly engaged at one end with a protruding end of said rod and extending vertically downward near to ground level, and having means by which the shaft may be rotated about its radial axis, whereby radial twisting of the actuator shaft causes said rod to turn on its radial axis.
Claim 3
Dependent Claim
25 words
A gutter system as recited in claim 1 wherein: said back half is immediately adjacent to the house or building and is fixedly attached thereto.
Claim 4
Dependent Claim
31 words
A gutter system as recited in claim 2 wherein: said back half has a piece at either end transverse to the gutter's longitudinal axis protruding outwardly from said house or building.
Claim 5
Dependent Claim
25 words
A gutter system as recited in claim 3 wherein: said rod protrudes at either end through said transverse pieces before gearingly engaging said actuator shaft.
Claim 6
Dependent Claim
31 words
A gutter system as recited in claim 4 wherein: said front half has a flange at either end transverse to the gutter's longitudinal axis protruding inwardly toward said house or building.
Claim 7
Dependent Claim
22 words
A gutter system as recited in claim 5 wherein: said transverse pieces overlap said flanges and the combination form the gutter ends.
Claim 8
Dependent Claim
45 words
A gutter system as recited in claim 6 wherein: said halves each have horizontal lower edges curved backward toward said house or building wherein the back half lower edge fits snugly within the front half lower edge forming a continuous hinge along the gutter bottom.
Claim 9
Dependent Claim
74 words
A gutter system as recited in claim 7 wherein: said back half is horizontally formed along its longitudinal axis into two portions, an upper portion and a bottom portion, whereby said upper portion lies in a generally vertical plane flat against said house or building and fixedly attached thereto, and said bottom portion is bent forward and outwardly from said house or building at an angle in the range of 30° to 45° .
Claim 10
Dependent Claim
27 words
A gutter system as recited in claim 8 wherein: said bracket assemblies lie in radial planes about said rod transverse to the longitudinal axis of the gutter.
Claim 11
Dependent Claim
44 words
A gutter system as recited in claim 9 wherein: each bracket assembly has two parts, a curved arm fixedly attached at one end to said gutter front half and a curved sleeve-type housing fixedly attached to and extending through said back half's bottom portion.
Claim 12
Dependent Claim
21 words
A gutter system as recited in claim 10 wherein: the curved arm's unattached end slideably fits into said curved, sleeve-type housing.
Claim 13
Dependent Claim
37 words
A gutter system as recited in claim 11 wherein: said curved arm has an opening defined along its central axis with upper and lower edges and has gear teeth along one of said edges of said opening.
Claim 14
Dependent Claim
34 words
A gutter system as recited in claim 12 wherein: said rod has a knurled gear formed concentrically about its surface circumference at each place on the rod where said rod engages a bracket assembly.
Claim 15
Dependent Claim
78 words
A gutter system as recited in claim 13 wherein: said rod is positioned through the bracket assembly arm opening so that the rod's knurled gear engages and meshes with the arm opening's gear teeth, such that as the rod is rotated about its radial axis said curved bracket arm will move out of or into the curved bracket housing causing the gutter front half to open or close accordingly, rotating about an axis formed along said continuous hinge.
