Abstract
Abstract A multipurpose, two-position ladder attachment for extending a ladder above overhanging roofs while bridging the eaves and gutters, for leaning against weak siding, and for installing heavy or bulky panels or windows in elevated openings. Elongated channels formed in two cantilevered brackets are clamped about the stiles of the ladder by a rod and wing nuts. The rod passes through hollow rungs of the ladder or in close proximity to the stiles if the rungs are not hollow. A flat padded board connected across the free ends of the brackets is positionable with its broad side horizontal or vertical when the ladder is leaned at a recommended angle.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
115 words
A multipurpose fixture for a ladder comprising, in combination: a pair of juxtapositioned brackets each including symmetrically opposite elongated channel means for engaging the outer sides of the ladder stiles, and support means extending from said channel means having a first edge at an obtuse angle with the length thereof for bearing a vertical load and a second edge normal to said first edge for bearing a lateral load, said obtuse angle being supplementary to a predetermined leaning angle of the ladder; securing means coupled to said brackets for clamping said channel means about the stiles engaged therein; and transverse means operatively connected to said brackets for selectively positioning against said first or second edge.
Claim 2
Dependent Claim
115 words
A multipurpose fixture for a ladder comprising, in combination: a pair of juxtapositioned brackets each including symmetrically opposite elongated channel means for engaging the outer sides of the ladder stiles, and support means extending from said channel means having a first edge at an obtuse angle with the length thereof for bearing a vertical load and a second edge normal to said first edge for bearing a lateral load, said obtuse angle being supplementary to a predetermined leaning angle of the ladder; securing means coupled to said brackets for clamping said channel means about the stiles engaged therein; and transverse means operatively connected to said brackets for selectively positioning against said first or second edge.
Claim 3
Dependent Claim
35 words
A fixture according to claim 1 wherein: said securing means includes a rod extending between said brackets, and a first fastener at one end of said rod for engaging said channel means about the stiles.
Claim 4
Dependent Claim
60 words
A fixture according to claim 2 wherein: said brackets include a first aperture positioned in each of said channel means for aligning with a hollow rung in the ladder; and said rod extends through said first apertures and for passing through the hollow rung, and said first fasteners clamp said brackets to the stiles at either end of said rod.
Claim 5
Dependent Claim
51 words
A fixture according to claim 2 wherein: said brackets include a first aperture positioned in each of said support means adjacent to said channel means; and said rod extends through said first apertures for extending across the exterior of the ladder, and first fasteners for clamping said brackets to the stiles.
Claim 6
Dependent Claim
52 words
A fixture according to claim 4 wherein: said brackets include a second aperture positioned in each of said channel means for aligning with a hollow rung in the ladder; and said rod is selectably removable from the hollow rung for extending across the exterior of the ladder adjacent to said channel means.
Claim 7
Dependent Claim
14 words
A fixture according to claim 1 wherein: said obtuse angle is substantially 1041/2 degrees.
Claim 8
Dependent Claim
38 words
A fixture according to claim 1 wherein: said transverse means includes a flat crossbar with one side connected to said brackets, and a resilient pad contiguously fixed to the other side and the long edges of said crossbar.
Claim 9
Dependent Claim
104 words
A fixture according to claim 1 wherein: said support means includes first apertures disposed a preselected distance from said first and second edges; and said transverse means includes a crossbar, a pair of angles with each having a first leg and second leg orthogonal to each other, said first legs secured to said crossbar and said second legs contiguous with respective ones of said support means and each having a second aperture disposed said preselected distance from said first leg, and first fasteners extending through said first and second apertures for fixing said angles to said support means in one of the selected positions.
Claim 10
Dependent Claim
31 words
A fixture according to claim 8 wherein: said first leg of each of said angles is interposed between said member and the upper edge or forward edge of said support member.
Claim 11
Dependent Claim
139 words
A two-position fixture for supporting a forwardly inclined ladder with hollow rungs a spaced distance from an upright surface, comprising, in combination: a pair of brackets each having an elongated channel for engaging opposite outer sides of the ladder at a selected rung, and a cantilever extending forwardly from said channel having an upper edge at an obtuse angle with the length of said channel, and a forward edge extending downwardly at a right angle from said upper edge, said obtuse angle being supplementary to a predetermined leaning angle of the ladder; a rod secured at its ends to said channels for extending through the selected rung and clamping said brackets to the ladder; and a crossbar operatively connected on one side to respective forward ends of said cantilevers for selectively engaging said upper edge or said forward edge.
Claim 12
Dependent Claim
139 words
A two-position fixture for supporting a forwardly inclined ladder with hollow rungs a spaced distance from an upright surface, comprising, in combination: a pair of brackets each having an elongated channel for engaging opposite outer sides of the ladder at a selected rung, and a cantilever extending forwardly from said channel having an upper edge at an obtuse angle with the length of said channel, and a forward edge extending downwardly at a right angle from said upper edge, said obtuse angle being supplementary to a predetermined leaning angle of the ladder; a rod secured at its ends to said channels for extending through the selected rung and clamping said brackets to the ladder; and a crossbar operatively connected on one side to respective forward ends of said cantilevers for selectively engaging said upper edge or said forward edge.
Claim 13
Dependent Claim
26 words
A fixture according to claim 10 further comprising: first fasteners threadingly connected to the ends of said rod for engaging said channel means about the stiles.
Claim 14
Dependent Claim
43 words
A fixture according to claim 11 wherein: said brackets include a first aperture positioned in each of said channels for aligning with a hollow rung in the ladder; and said rod extends through said first apertures and for passing through the hollow rung.
Claim 15
Dependent Claim
39 words
A fixture according to claim 10 wherein: said brackets include a first aperture positioned in each of said cantilevers adjacent to said channel; and said rod extends through said first apertures for extending across the exterior of the ladder.
Claim 16
Dependent Claim
50 words
A fixture according to claim 13 wherein: said brackets include a second aperture positioned in each of said channels for aligning with a hollow rung in the ladder; and said rod is selectably removable from the hollow rung for extending across the exterior of the ladder adjacent to said channels.
