Abstract
The present invention relates to tools for removing shingles, nails and other materials from a roof or other surface. A tool of the invention, in certain embodiments, comprises blades that move in preferably a reciprocating manner to pry up shingles, nails and other materials. A tool of the invention, in certain embodiments, can be powered through a remote power source to move the blades. In certain other embodiments, a tool of the invention comprises a drive-wheel which is rotated through force form a remote power source.
Claims9
A tool for removing shingles comprising:
- a bar;
- a handle;
- a spade assembly, said spade assembly comprising from 2 to 2000 blades;
- a drive-wheel;
- a powering mechanism to facilitate a powered reciprocating motion of said blades and a powered rotation of said drive-wheel, said powering mechanism being operably coupled with the drive-wheel for said powered rotation of said drive-wheel moving the tool forward, said powering mechanism also being operably coupled with a drive shaft connected to said blades resulting in said reciprocating movement of said blades moving the blades forward and backward;
- a guide including a guide shaft moveable therein said guide shaft connected to the blades, wherein said guide facilitates said blades engaging in said reciprocating movement without rotation around said drive shaft;
- wherein power is delivered through said bar to said powering mechanism;
- wherein said blades comprise a leading edge and a body, said leading edge engaging said shingled surface at a shallower angle than said body;
- and
- wherein said blades are capable of prying up shingles on a roof through forward motion.

A method for removing shingles comprising the steps of:
- providing a tool having a bar, a handle, a spade assembly, said spade assembly comprising from 2 to 2000 blades, a drive-wheel, a powering mechanism to facilitate a powered reciprocating motion of said blades and a powered rotation of said drive-wheel, said powering mechanism being operably coupled with the drive-wheel for said powered rotation of said drive-wheel moving the tool forward, said powering mechanism also being operably coupled with a drive shaft connected to said blades resulting in said reciprocating movement of said blades moving the blades forward and backward, a guide including a guide shaft moveable therein said guide shaft connected to the blades, wherein said guide facilitates said blades engaging in said reciprocating movement without rotation around said drive shaft, wherein power is delivered through said bar to said powering mechanism, wherein said blades comprise a leading edge and a body, said leading edge engaging said shingled surface at a shallower angle than said body;
- and
- removing shingles by said blades capable of prying up shingles on a roof through forward motion.
