Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
144 words
An earthworking machine comprising a chassis, a first turret mounted for rotation about an axis of rotation on said chassis, a first beam means having one end connected to said first turret and extending from said first turret, an earthworking implement mounted on the end of said first beam means opposite the end of said beam connected to saId first turret, a second turret mounted for rotation on said chassis coaxially with said first turret, a second beam means having one end connected to said second turret and extending from said second turret and a second earthworking implement mounted on the end of said second beam means opposite the connection of said second beam to said second turret whereby either of said earthworking implements is usable as a counterweight to the other earthworking implements during operation of the other earthworking implement of the machine.
Claim 2
Dependent Claim
144 words
An earthworking machine comprising a chassis, a first turret mounted for rotation about an axis of rotation on said chassis, a first beam means having one end connected to said first turret and extending from said first turret, an earthworking implement mounted on the end of said first beam means opposite the end of said beam connected to saId first turret, a second turret mounted for rotation on said chassis coaxially with said first turret, a second beam means having one end connected to said second turret and extending from said second turret and a second earthworking implement mounted on the end of said second beam means opposite the connection of said second beam to said second turret whereby either of said earthworking implements is usable as a counterweight to the other earthworking implements during operation of the other earthworking implement of the machine.
