Abstract

Abstract A scraping blade, for the removal of various surface coatings in combination with a scraping device, providing substantially flat rectangular angularly separate laterially connecting portions being primarily angularly divided and thereafter arranged so as to form a pair of individual angularly outspread apart principally similarly configured distinctly separate blade members, so as to be reversible in being attached or mounted to a scraping device by one blade member, with the other successive blade member, being angularly separated and disposed, entirely and completely independent of further support or support apparatus, having a cutting edge located on the outermost extreme, so as to engage and perform scraping on a work surface.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 114 words
A scraping blade, for use on a dual blade scraping device, for the removal of various surface coatings, said scraping blade comprised of substantially flat rectangular separate laterally connecting portions being angularly disposed and arranged so as to form a pair of individual angularly outspread apart principally similarly configured distinctly separate blade members, being initially adjoining and, therefrom, being immediately subsequently thereafter outwardly disposed and angularly divided apart, said blade members individually comprising, an initially outwardly disposed portion, which may have a opening near midway, thereon, of which a securing device might pass through, and a then inwardly disposed portion, having a bevelled cutting edge, thereon, inwardly inclined and located on the outermost extreme.
Claim 2
Dependent Claim 114 words
A scraping blade, for use on a dual blade scraping device, for the removal of various surface coatings, said scraping blade comprised of substantially flat rectangular separate laterally connecting portions being angularly disposed and arranged so as to form a pair of individual angularly outspread apart principally similarly configured distinctly separate blade members, being initially adjoining and, therefrom, being immediately subsequently thereafter outwardly disposed and angularly divided apart, said blade members individually comprising, an initially outwardly disposed portion, which may have a opening near midway, thereon, of which a securing device might pass through, and a then inwardly disposed portion, having a bevelled cutting edge, thereon, inwardly inclined and located on the outermost extreme.
Claim 3
Dependent Claim 32 words
The scraping blade of claim 1, wherein, said scraping blade being principally so configured to be attached or mounted to said dual blade scraping device to perform scraping on a work surface.
Claim 4
Dependent Claim 61 words
The scraping blade of claim 1, wherein, said scraping blade having a pair of individual angularly outspread apart distinctly separate blade members, to be attached or mounted to said dual blade scraping device by one blade member, thereof, with the other successive blade member, thereof, being angularly disposed and separated, therefrom, entirely and completely independent of further support or support apparatus.
Claim 5
Dependent Claim 69 words
The scraping blade of claim 1, wherein, said scraping blade having a pair of individual angularly outspread apart distinctly separate blade members, to be attached or mounted to said dual blade scraping device by one blade member, thereof, with the other successive blade member, thereof, being angularly disposed and separated, therefrom, having a cutting edge, thereon, located on the outermost extreme, thereof, so as to engage a work surface.
Claim 6
Dependent Claim 37 words
The scraping blade of claim 1, wherein, said scraping blade comprising a pair of principally similarly configured blade members so as to be optionally attached or mounted to said dual blade scraping device by either blade member.
Claim 7
