Abstract
Abstract A manually held and manipulated knife for trimming a comestible product such as meat having a frame or frame assembly including a hand grasp or handle part extending radially outwardly from a ring-like part of short axial length and of considerable greater diameter than its axial length, a power driven ring-like blade also of short axial length rotatably supported in the ring-like part of the handle and having a radially inwardly facing circular cutting edge at one axial end, and a ring-like depth of cut control or gauge member within the blade and connected to the frame assembly for adjustment lengthwise of the axis of the blade by screws located radially outwardly of the gauge member. Clearance is provided between the blade and the depth of cut control or gauge member which clearance increases in the direction away from the cutting edge of the blade. The part of the depth of cut control or gauge member spaced from its connection to the frame assembly is flexible.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
A gauge for a hand-held and manipulated knife for trimming a comistable product, such as, meat, and having a handle projecting radially from an annular ring-like member of short axial length in which a ring-like blade of short axial length having an annular cutting edge at one end is rotatably supported and power driven, said gauge assembly comprising an annular tubular-like member having a base part at one side adapted for connection to the knife and a flexible ring-like gauge part proper integral with said base part, at least one end of said gauge member being planar and joined by an exterior conical surface diverging therefrom.
Claim 2
Dependent Claim
106 words
A gauge for a hand-held and manipulated knife for trimming a comistable product, such as, meat, and having a handle projecting radially from an annular ring-like member of short axial length in which a ring-like blade of short axial length having an annular cutting edge at one end is rotatably supported and power driven, said gauge assembly comprising an annular tubular-like member having a base part at one side adapted for connection to the knife and a flexible ring-like gauge part proper integral with said base part, at least one end of said gauge member being planar and joined by an exterior conical surface diverging therefrom.
Claim 3
Dependent Claim
35 words
A gauge as claimed in claim 1 in which said conical surface of said gauge member diverges from said planar end surface of said gauge member at an angle of from about 110° to 130°.
Claim 4
Dependent Claim
28 words
A gauge as claimed in claim 1 in which said conical surface of said gauge member diverges from said planar end thereof at an angle of about 120°.
Claim 5
Dependent Claim
162 words
A hand-held and manipulated knife for trimming a comistable product such as, meat and having a frame assembly including a handle projecting radially from an annular member of short axial length in which a ring-like blade of short axial length having an annular cutting edge at one end is rotatably supported and power driven, a gauge assembly comprising an annular tubular-like member within and concentric with said blade and having a base part at one side connected to said frame assembly of said knife and a flexible ring-like gauge part proper connected to said base part, the end of said gauge member adjacent to the cutting edge of said blade being planar and joined by an exterior conical surface diverging therefrom and spaced from the interior surface of said blade to provide a gap or space between said blade and said gauge member for the passage of a slice therethrough and means for adjusting said gauge member axially of said knife blade.
Claim 6
Dependent Claim
162 words
A hand-held and manipulated knife for trimming a comistable product such as, meat and having a frame assembly including a handle projecting radially from an annular member of short axial length in which a ring-like blade of short axial length having an annular cutting edge at one end is rotatably supported and power driven, a gauge assembly comprising an annular tubular-like member within and concentric with said blade and having a base part at one side connected to said frame assembly of said knife and a flexible ring-like gauge part proper connected to said base part, the end of said gauge member adjacent to the cutting edge of said blade being planar and joined by an exterior conical surface diverging therefrom and spaced from the interior surface of said blade to provide a gap or space between said blade and said gauge member for the passage of a slice therethrough and means for adjusting said gauge member axially of said knife blade.
Claim 7
Dependent Claim
31 words
A knive as claimed in claim 4 in which said conical surface of said gauge member diverges from said planar end thereof at an angle of from about 110° to 130°.
Claim 8
Dependent Claim
28 words
A knife as claimed in claim 4 in which said conical surface of said gauge member diverges from said planar end thereof at an angle of about 120°.
Claim 9
Dependent Claim
68 words
A knife as claimed in claim 4 in which said means for adjusting said gauge member axially of said blade comprises at least one flanged threaded fastener in a tapped aperture in the frame assembly of the knife the flange of which fastener engages in a slot in the circumference of the base part of the gauge member, said flanged fastener being radially outwardly of the gauge member.
