Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
91 words
In a blade cleaning apparatus for removing residual material from a moving imaging surface of a reproducing machine, said apparatus comprising: a blade for engaging said surface to remove said material; means for supporting said blade for movement between a position wherein it is in operative engagement with said surface, and a position wherein it is separated from said surface; the improvement wherein, said apparatus further comprises: means for vibrating said blade when it is separated from said surface for shaking off said residual material and foreign material from said blade.
Claim 2
Dependent Claim
91 words
In a blade cleaning apparatus for removing residual material from a moving imaging surface of a reproducing machine, said apparatus comprising: a blade for engaging said surface to remove said material; means for supporting said blade for movement between a position wherein it is in operative engagement with said surface, and a position wherein it is separated from said surface; the improvement wherein, said apparatus further comprises: means for vibrating said blade when it is separated from said surface for shaking off said residual material and foreign material from said blade.
Claim 3
Dependent Claim
76 words
An apparatus as in claim 1, wherein said blade support means includes a support member, a blade holder supported by said support member, and means for pivotably supporting said blade holder for movement about an axis extending longitudinally of said surface, and wherein said vibrating means comprises means for rocking said blade holder about said axis so that it alternately collides with said support member, whereby said blade is caused to vibrate to remove said materials.
Claim 4
Dependent Claim
68 words
An apparatus as in claim 2, wherein said support member is arranged for pivoting movement so as to pivotally support said blade holder and said blade for movement between said positions and wherein said means for moving said blade between said positions comprises a solenoid connected to said support member, which is operative to move said blade to said separated position upon the stopping of said imaging surface.
Claim 5
Dependent Claim
65 words
An apparatus as in claim 3, wherein said vibrating means further comprises a first solenoid and a second solenoid arranged at respective ends of said support member, and adjacent corresponding ends of said blade whereby alternate actuation of said first and second solenoids causes said blade holder to rock about said axis so that said ends of said blade alternately collide with said support member.
