Abstract
Abstract An elongated handle has mounted on one end thereof a plurality of spring fingers in side by side relation with toothed rotable cutter disc on free ends of the fingers. The free ends of the fingers are movable toward and away from each other to adjust themselves to the spacing of the grooves in the grill to be cleaned and are movable in a perpendicular direction to adjust themselves to the thickness of deposits in the grooves. The handle also carries a brush to sweep out debris loosened by the cutter discs.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
173 words
A grooved grill cleaner comprising an elongated handle, a plurality of spring fingers extending in side by side relation in a common plane from the distal end of said handle, and cutters mounted on free ends of said fingers for movement along the grooves in said grill to clean the grooves, the free ends of said fingers being movable relative to each other in said common plane to adjust themselves to the spacing or irregularities of said grooves and movable perpendicular to said common plane relative to each other to adjust themselves to the thickness of deposits in the grooves, said cutters being disposed transversely of said fingers for said movement along said grooves, said cutters comprising cutter discs rotatably mounted on said fingers, each of said cutter discs comprising a washer having teeth formed by perpheral radial cuts in the washer, said teeth being twisted out of the plane of the washer with the ends of the teeth presenting a substantially continuous circumference on the washer without circumferential gaps between the teeth.
Claim 2
Dependent Claim
173 words
A grooved grill cleaner comprising an elongated handle, a plurality of spring fingers extending in side by side relation in a common plane from the distal end of said handle, and cutters mounted on free ends of said fingers for movement along the grooves in said grill to clean the grooves, the free ends of said fingers being movable relative to each other in said common plane to adjust themselves to the spacing or irregularities of said grooves and movable perpendicular to said common plane relative to each other to adjust themselves to the thickness of deposits in the grooves, said cutters being disposed transversely of said fingers for said movement along said grooves, said cutters comprising cutter discs rotatably mounted on said fingers, each of said cutter discs comprising a washer having teeth formed by perpheral radial cuts in the washer, said teeth being twisted out of the plane of the washer with the ends of the teeth presenting a substantially continuous circumference on the washer without circumferential gaps between the teeth.
Claim 3
Dependent Claim
26 words
A grill cleaner as defined in claim 1, there being a pair of said cutter discs axially apart from each other on each of said fingers.
Claim 4
Dependent Claim
59 words
A grill cleaner as defined in claim 1, each finger having a cutter disc pivot pin angled in one direction away from the direction of the finger, said teeth being twisted further in the same direction as said pivot pin to cause the cutter disc to rotate when said fingers are pulled lengthwise in said grooves of the grill.
Claim 5
Dependent Claim
162 words
A grooved grill cleaner comprising an elongated handle, a plurality of spring fingers extending in side by side relation in a common plane from the distal end of said handle, and cutters mounted on free ends of said fingers for movement along the grooves in said grill to clean the grooves, the free ends of said fingers being movable relative to each other in said common plane to adjust themselves to the spacing or irregularities of said grooves and movable perpendicular to said common plane relative to each other to adjust themselves to the thickness of deposits in the grooves, said cutters being disposed transversely of said fingers for said movement along said grooves, a flat plate on said distal end of the handle, said fingers comprising flat strips of spring material pivotally mounted on said plate for said movements in said common plane, and said free ends of said fingers supporting said cutters being bent substantially perpendicular to said common plane.
Claim 6
Dependent Claim
162 words
A grooved grill cleaner comprising an elongated handle, a plurality of spring fingers extending in side by side relation in a common plane from the distal end of said handle, and cutters mounted on free ends of said fingers for movement along the grooves in said grill to clean the grooves, the free ends of said fingers being movable relative to each other in said common plane to adjust themselves to the spacing or irregularities of said grooves and movable perpendicular to said common plane relative to each other to adjust themselves to the thickness of deposits in the grooves, said cutters being disposed transversely of said fingers for said movement along said grooves, a flat plate on said distal end of the handle, said fingers comprising flat strips of spring material pivotally mounted on said plate for said movements in said common plane, and said free ends of said fingers supporting said cutters being bent substantially perpendicular to said common plane.
Claim 7
Dependent Claim
48 words
A grill cleaner as defined in claim 4, said pivotal mounting of said fingers on said plate comprising a pair of pins in each finger extending through holes in said plate which are larger than the pins to allow limited pivotal movement of the fingers on said plate.
Claim 8
Dependent Claim
39 words
A grill cleaner as defined in claim 4 including a pivot pin in said bent free end of each finger, said cutters comprising a pair of cutter discs rotatably mounted on said pin on opposite sides of said finger.
Claim 9
Dependent Claim
32 words
A grill cleaner as defined in claim 4, said plate extending along said fingers in divergent relation thereto to limit the bending of the fingers when they are pressed into said grooves.
Claim 10
Dependent Claim
23 words
A grill cleaner as defined in claim 4 including a brush mounted on said plate to sweep out debris loosened by said cutters.
