Apparatus for installing shingles onto a roof

A cart-like apparatus for applying shingles to a roof comprising:

• (a) a rigid framework having front, rear and upper portions and uphill and downhill side portions,
• (b) a pair of rear wheels positioned at opposite extremities of an axle pivotably mounted adjacent its center to the lower rear portion of said framework, said axle being disposed substantially perpendicularly to said side portions,
• (c) a storage compartment positioned adjacent the upper portion of said framework and adapted to hold flexible roofing shingles,
• (d) handle means associated with said framework and disposed substanially above said rear wheels,
• (e) a conduit guide adapted to receive and direct said shingles downwardly into proper position on a roof,
• (f) a stabilizer wheel mounted adjacent the lower front portion of said framework, the plane of rotation of said wheel being substantially perpendicular to said pivotably mounted axle,
• (g) an activator wheel positioned in opposed relationship to said stabilizer wheel, mounted so as to have a vertically adjustable axis of rotation, and adapted to roll upon a roof in non-slipping engagement therewith,
• (h) spaced control means associated with said activator wheel and
• (i) automatic fastener means associated with said framework in a manner adapted to undergo repetitive lifting and falling movement in response to said spaced control means, whereby fasteners are forced at spaced intervals into underlying shingles with each falling movement of said fastener means.
