Abstract
Abstract A method and construction of a saw blade whereby the ends of a saw blade are secured to define an endless saw blade construction which has a series of cutting teeth progressively arranged from leading to trailing end so that the respective teeth are rendered self-feeding. Each cutting tooth is formed with a relatively wide root which is inclined to define a clearance angle of 10° to 15°.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
49 words
A method of forming an endless band saw blade comprising the steps of: forming a saw blade so as to place the opposed ends of the blade into abutting relationship, offsetting the abutted ends with respect to one another, and securing the abutted ends together in said offset relationship.
Claim 2
Independent Claim
49 words
A method of forming an endless band saw blade comprising the steps of: forming a saw blade so as to place the opposed ends of the blade into abutting relationship, offsetting the abutted ends with respect to one another, and securing the abutted ends together in said offset relationship.
Claim 3
Dependent Claim
31 words
The method as defined in claim 1 and including the steps of: shaping the back edge of the blade to define a back edge which is coincidental to a common plane.
Claim 4
Independent Claim
86 words
A method of forming an endless saw blade comprising the steps of: joining together in end to end relationship a plurality of saw blade segments having a series of cutting teeth formed along one edge thereof whereby the adjacent end of successive saw blade segments are in offset relationship, securing the abutted adjacent ends to one another in said offset relationship, and forming the back edge of the respective saw blade segments so as to define a back edge which is coincidental to a common plane.
Claim 5
Independent Claim
86 words
A method of forming an endless saw blade comprising the steps of: joining together in end to end relationship a plurality of saw blade segments having a series of cutting teeth formed along one edge thereof whereby the adjacent end of successive saw blade segments are in offset relationship, securing the abutted adjacent ends to one another in said offset relationship, and forming the back edge of the respective saw blade segments so as to define a back edge which is coincidental to a common plane.
Claim 6
Dependent Claim
26 words
The method as defined in claim 3 wherein the cutting teeth are formed as to be progressively disposed at an angle to the said back edge.
Claim 7
Dependent Claim
32 words
The method as defined in claim 2 wherein said saw blade has its cutting teeth progressively sloped so that each tooth effects a progressive cut when the blade is placed in use.
Claim 8
Independent Claim
70 words
A method of forming a saw blade comprising the steps of: forming a saw blade with a plurality of cutting teeth, offsetting sections of said saw blade with respect to one another, and shaping the back edge of the blade to define a back edge which is coincidental to a common plane, and whereby the cutting teeth of the respective sections are progressively sloped with respect to said back edge.
Claim 9
Independent Claim
70 words
A method of forming a saw blade comprising the steps of: forming a saw blade with a plurality of cutting teeth, offsetting sections of said saw blade with respect to one another, and shaping the back edge of the blade to define a back edge which is coincidental to a common plane, and whereby the cutting teeth of the respective sections are progressively sloped with respect to said back edge.
Claim 10
Dependent Claim
19 words
The method as defined in claim 6 and including the step of forming each tooth with a clearance angle.
Claim 11
Dependent Claim
42 words
The method as defined in claim 6 wherein the respective teeth are progressively sloped in a diverging manner relative to the direction of cutting so that each succeeding tooth makes a progressively deeper cut in a work piece during a cutting operation.
