Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
108 words
Deflector apparatus for a harvesting topper, said deflector apparatus comprising: an upstanding carrier having an upstanding axis and a surface facing laterally outwardly with respect to said axis; a deflector on said carrier, and projecting laterally outwardly therefrom, said deflector having two side edges circumferentially spaced from each other on the laterally outwardly facing surface of said carrier and a curved outwardly convex deflector surface extending between said two side edges, said deflector surface facing generally laterally outwardly with respect to said laterally outwardly facing surface of said carrier; and means connected to said carrier for mounting said deflecting apparatus for rotation about the axis of said carrier.
Claim 2
Dependent Claim
108 words
Deflector apparatus for a harvesting topper, said deflector apparatus comprising: an upstanding carrier having an upstanding axis and a surface facing laterally outwardly with respect to said axis; a deflector on said carrier, and projecting laterally outwardly therefrom, said deflector having two side edges circumferentially spaced from each other on the laterally outwardly facing surface of said carrier and a curved outwardly convex deflector surface extending between said two side edges, said deflector surface facing generally laterally outwardly with respect to said laterally outwardly facing surface of said carrier; and means connected to said carrier for mounting said deflecting apparatus for rotation about the axis of said carrier.
Claim 3
Dependent Claim
34 words
Deflector apparatus according to claim 1 wherein said laterally outwardly facing surface of said carrier is circular in cross-section transverse to said axis, said deflector being rigidly attached to said laterally outwardly facing surface.
Claim 4
Dependent Claim
11 words
Deflector apparatus according to claim 2 wherein said carrier is cylindrical.
Claim 5
Dependent Claim
24 words
Deflector apparatus according to claim 2 wherein said deflector, in cross section transverse to said axis, is symmetrical about a radius of said carrier.
Claim 6
Dependent Claim
19 words
Deflector apparatus according to claim 4 further comprising a plurality of said deflectors symmetrically circumferentially spaced about said carrier.
Claim 7
Dependent Claim
14 words
