Abstract
Abstract A blade for a material stripping machine including a movable carriage on which is located a motor for providing reciprocating motion to a blade member having a cutting edge for stripping material. The cutting edge of the blade member comprises a series of beveled teeth, and the body of the blade member has projecting upwardly therefrom at least one subsidiary cutting member having a cutting edge facing the cutting edge of the blade member for cutting through material stripped by the blade. The blade may also be provided in the form of a hand tool which may be used to remove shingles. Preferably a plurality of slots are provided in the recesses between the teeth to enable removal of shingle nails.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
117 words
A manual stripping tool for stripping material such as shingles comprising a shovel-like stripping member adapted to be attached to a handle member for manipulating the stripping tool, said stripping member comprising a body having a flat plane surface for receiving stripped material and further having a cutting edge at its front end comprised of a plurality of beveled teeth for stripping material, and said body further having a pair of laterally spaced subsidiary members projecting upwardly from said body for wedging upwardly material to be stripped by said cutting edge, said subsidiary member being flanged outwardly from said flat plane surface so that they meet said plane surface at an obtuse angle between 90* and 180*.
Claim 2
Dependent Claim
117 words
A manual stripping tool for stripping material such as shingles comprising a shovel-like stripping member adapted to be attached to a handle member for manipulating the stripping tool, said stripping member comprising a body having a flat plane surface for receiving stripped material and further having a cutting edge at its front end comprised of a plurality of beveled teeth for stripping material, and said body further having a pair of laterally spaced subsidiary members projecting upwardly from said body for wedging upwardly material to be stripped by said cutting edge, said subsidiary member being flanged outwardly from said flat plane surface so that they meet said plane surface at an obtuse angle between 90* and 180*.
Claim 3
Dependent Claim
55 words
The manual stripping tool of claim 1 wherein said subsidiary members project upwardly only a slight amount adjacent said cutting edge and are tapered gradually upwardly as they extend rearwardly away from the cutting edge so that they project upwardly from said flat surface a greater amount at a point rearward of said cutting edge.
Claim 4
Dependent Claim
21 words
The manual stripping tool of claim 1 wherein said subsidiary members are formed with knife-edge cutting edges on their uppermost surfaces.
Claim 5
Dependent Claim
60 words
The manual stripping tool of claim 1 wherein said cutting edge has a number of elongated slots opening into the cutting edge between adjacent teeth for receiving and removing nails or tacks, the width of said slots being less than the diameter of the head of the nail to be pried out by engagement of the blade under the head.
Claim 6
Dependent Claim
146 words
a manual stripping tool for stripping material such as shingles comprising a shovel-like stripping member adapted to be attached to a handle member for manipulating the stripping tool, said stripping member comprising a body having a surface for receiving stripped material and having a cutting edge at its front end comprised of a plurality of beveled teeth for stripping material, and a pair of laterally spaced subsidiary members projecting upwardly from said body for wedging upwardly material to be stripped by said cutting edge, and wherein said cutting edge has a number of elongated slots opening into the cutting edge between adjacent teeth for receiving and removing roofing nails or tacks, the width of said slots being less than the diameter of the head of the nails to enable the nail to be pried out by engagement of the blade under the head of the nail.
Claim 7
Dependent Claim
146 words
a manual stripping tool for stripping material such as shingles comprising a shovel-like stripping member adapted to be attached to a handle member for manipulating the stripping tool, said stripping member comprising a body having a surface for receiving stripped material and having a cutting edge at its front end comprised of a plurality of beveled teeth for stripping material, and a pair of laterally spaced subsidiary members projecting upwardly from said body for wedging upwardly material to be stripped by said cutting edge, and wherein said cutting edge has a number of elongated slots opening into the cutting edge between adjacent teeth for receiving and removing roofing nails or tacks, the width of said slots being less than the diameter of the head of the nails to enable the nail to be pried out by engagement of the blade under the head of the nail.
