Abstract
Abstract A road surface removing machine including a modular assemblage, having a rotary cutter drum unit with flailing arms adapted to impact upon a road surface for disintegration of the surface, said drum unit having four degrees of movement, boom means associated with a rail means assemblage for operative movement of the cutter drum, outrigger means for stabilizing the machine, a vacuum operated system for picking up disintegrated road surface debris and depositing it in a separation bin, and an hydraulic circuitry for operation of the components of the machine.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
191 words
A machine for cutting a road surface to a predetermined depth, said machine comprising a modular assemblage mountable upon the chassis of a motor vehicle of the truck type, said modular assemblage including a cutter drum unit having a cutter drum assemblage, first means to move the cutter drum unit along a vertical axis, second means to rotate the cutter drum unit 90° about the vertical axis, third means to move the cutter drum unit laterally relative to the chassis, fourth means to move the cutter drum unit longitudinally relative to the chassis, a control console having means arranged for operation of said first, second, third and fourth means either individually or in combination, said cutter drum assemblage having a pluraity of cutter arms each rotatable 360° in planes parallel with said cutter drum unit vertical axis, each of said cutter arms having a cutter bit at one end an enlarged portion at the opposite end arranged to have the center of percussion of the cutter arm coincide with the cutter bit and means to rotate the cutter drum assemblage whereby the cutter bits will successively impact upon the road surface.
Claim 2
Dependent Claim
191 words
A machine for cutting a road surface to a predetermined depth, said machine comprising a modular assemblage mountable upon the chassis of a motor vehicle of the truck type, said modular assemblage including a cutter drum unit having a cutter drum assemblage, first means to move the cutter drum unit along a vertical axis, second means to rotate the cutter drum unit 90° about the vertical axis, third means to move the cutter drum unit laterally relative to the chassis, fourth means to move the cutter drum unit longitudinally relative to the chassis, a control console having means arranged for operation of said first, second, third and fourth means either individually or in combination, said cutter drum assemblage having a pluraity of cutter arms each rotatable 360° in planes parallel with said cutter drum unit vertical axis, each of said cutter arms having a cutter bit at one end an enlarged portion at the opposite end arranged to have the center of percussion of the cutter arm coincide with the cutter bit and means to rotate the cutter drum assemblage whereby the cutter bits will successively impact upon the road surface.
Claim 3
Dependent Claim
74 words
A machine according to claim 1, wherein said first means includes a piston assemblage operatively connected to the cutter drum unit, said second means includes a cylinder and linkage assemblage operatively connected to the cutter drum unit, said third means includes a screw shaft operatively connected to the cutter drum unit, and said fourth means includes a cylinder and piston assemblage which is operatively connected to a horizontal rail means supporting said screw shaft.
Claim 4
Dependent Claim
63 words
A machine according to claim 1, wherein said modular assemblage has a debris pickup means including a nozzle and hose arrangement wherein a suction condition may be generated to pick up road surface cuttings for delivery to a bin mounted upon the chassis, said bin being tiltable for discharge of the debris therein when such discharge action is desired by the machine operator.
Claim 5
Dependent Claim
35 words
A machine according to claim 3, wherein said nozzle is positioned in close proximity to the road surface and adjacent the cutter drum assemblage to directly collect the debris being produced by cutter bit action.
