Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
205 words
In vehicular apparatus for multiple grooving of pavement, including a vehicle frame, support means carried by the frame, a plurality of cutter assemblies supported thereby, each having a rotatable cutter head, and means for rotating the cutter heads of such assemblies to groove pavement in contact therewith, the improvement comprising a ganged arrangement of the cutter assemblies, including a first pair of cutter assemblies spaced laterally apart from one another and a second pair of cutter assemblies spaced laterally apart from one another, the respective pairs of cutter assemblies being spaced longitudinally apart from one another relative to the direction of vehicular travel, wherein the lateral spacing of a pair of cutter assemblies is variable between an extended position for use in cutting and a retracted stowed position, including auxiliary support means accommodating lateral movement of the cutter assemblies between the extended and retracted positions comprising tracks extending laterally along main support means for each such cutter assembly, and track-engaging means carried by the vehicle frame adjacent such support means of each such cutter assembly and mounted for rotation on a substantially vertical axis, providing coincident rotational movement of the track-engaging means and lateral movement of the cutter assemblies supported at least in part thereby.
Claim 2
Dependent Claim
205 words
In vehicular apparatus for multiple grooving of pavement, including a vehicle frame, support means carried by the frame, a plurality of cutter assemblies supported thereby, each having a rotatable cutter head, and means for rotating the cutter heads of such assemblies to groove pavement in contact therewith, the improvement comprising a ganged arrangement of the cutter assemblies, including a first pair of cutter assemblies spaced laterally apart from one another and a second pair of cutter assemblies spaced laterally apart from one another, the respective pairs of cutter assemblies being spaced longitudinally apart from one another relative to the direction of vehicular travel, wherein the lateral spacing of a pair of cutter assemblies is variable between an extended position for use in cutting and a retracted stowed position, including auxiliary support means accommodating lateral movement of the cutter assemblies between the extended and retracted positions comprising tracks extending laterally along main support means for each such cutter assembly, and track-engaging means carried by the vehicle frame adjacent such support means of each such cutter assembly and mounted for rotation on a substantially vertical axis, providing coincident rotational movement of the track-engaging means and lateral movement of the cutter assemblies supported at least in part thereby.
Claim 3
Dependent Claim
104 words
Vehicular apparatus for multiple grooving of pavement, wherein a vehicle frame carries support means for a plurality of cutter assemblies rotatable to groove pavement in contact therewith, comprising five cutter assemblies ganged for use in a W plane, with a cutter assembly at each apex and each end of the W, wherein the pair of cutter assemblies more widely spaced from one another, at use locations corresponding to the ends of the W, are retractable to stowed position, including auxiliary support means, the latter pair of cutter assemblies and rotatable track-engaging means adjacent each such edge, accommodating movement thereof between use and stowed positions.
Claim 4
Dependent Claim
104 words
Vehicular apparatus for multiple grooving of pavement, wherein a vehicle frame carries support means for a plurality of cutter assemblies rotatable to groove pavement in contact therewith, comprising five cutter assemblies ganged for use in a W plane, with a cutter assembly at each apex and each end of the W, wherein the pair of cutter assemblies more widely spaced from one another, at use locations corresponding to the ends of the W, are retractable to stowed position, including auxiliary support means, the latter pair of cutter assemblies and rotatable track-engaging means adjacent each such edge, accommodating movement thereof between use and stowed positions.
Claim 5
Dependent Claim
99 words
In vehicular apparatus for multiple grooving of pavement, including a vehicle frame, support means carried by the frame, a plurality of cutter assemblies supported thereby having rotatable cutter heads, and means for rotating the cutter heads of such assemblies to groove pavement in contact therewith, means for supporting at least one of such assemblies for lateral movement between an inboard stowed position and an outboard operating position comprising tracks along the main support means for each of the latter pair of cutter assemblies and rotatable track-engaging means adjacent each such edge, accommodating movement thereof between use and stowed positions.
Claim 6
Dependent Claim
99 words
In vehicular apparatus for multiple grooving of pavement, including a vehicle frame, support means carried by the frame, a plurality of cutter assemblies supported thereby having rotatable cutter heads, and means for rotating the cutter heads of such assemblies to groove pavement in contact therewith, means for supporting at least one of such assemblies for lateral movement between an inboard stowed position and an outboard operating position comprising tracks along the main support means for each of the latter pair of cutter assemblies and rotatable track-engaging means adjacent each such edge, accommodating movement thereof between use and stowed positions.
Claim 7
Dependent Claim
44 words
Pavement grooving apparatus according to claim 3, wherein a pair of laterally spaced cutter assemblies are provided with such auxiliary support means, and wherein the respective tracks are at different levels for partial overlapping and nesting thereof upon retraction to the stowed inboard position.
Claim 8
Dependent Claim
23 words
Pavement grooving apparatus according to claim 4, wherein the pair of cutter assemblies are laterally spaced on opposite sides of the vehicle frame.
Claim 9
Dependent Claim
83 words
In vehicular apparatus for multiple grooving of pavement, including a vehicle frame, a cutter assembly depending therefrom having a cutter head rotatable about a substantially horizontal axis to produce multiple grooves in pavement when in contact therewith, the improvement comprising means interconnecting the cutter assembly to the frame for vertical and lateral movement relative thereto, including substantially vertically extending means for lowering and lifting the cutter assembly and transversely extending means for moving the cutter assembly laterally substantially parallel to the head axis.
Claim 10
Dependent Claim
83 words
In vehicular apparatus for multiple grooving of pavement, including a vehicle frame, a cutter assembly depending therefrom having a cutter head rotatable about a substantially horizontal axis to produce multiple grooves in pavement when in contact therewith, the improvement comprising means interconnecting the cutter assembly to the frame for vertical and lateral movement relative thereto, including substantially vertically extending means for lowering and lifting the cutter assembly and transversely extending means for moving the cutter assembly laterally substantially parallel to the head axis.
Claim 11
Dependent Claim
33 words
Pavement grooving apparatus according to claim 6, wherein the transversely extending means includes tracks and rollers adapted to extend the cutter assembly outboard of the vehicle frame and to retract it inboard thereof.
Claim 12
Dependent Claim
25 words
Pavement grooving apparatus according to claim 7, wherein the frame carries such tracks affixed thereto, and the cutter assembly carries such rollers axially affixed thereto.
Claim 13
Dependent Claim
76 words
In vehicular apparatus for multiple grooving of pavement, including a vehicle frame, a cutter assembly depending therefrom having a cutter head rotatable about a substantially horizontal axis to produce multiple grooves in pavement when in contact therewith, the improvement in supporting means for such cutter assembly comprising a subframe carried by and movable laterally relative to the vehicle frame and carrying the cutter assembly at essentially constant height for movement horizontally outboard and inboard relative thereto.
