Abstract
Abstract A new curb and gutter machine used in combination with a vehicle and characterized by its construction to include an adjustable cutter for trimming along the side of a roadway or curb, a sweeper for removing not only trimmed material but also other debris which might be along the side of the roadway, and a vacuum head for transferring the debris into a receptacle that is preferably mounted at the rear of the vehicle. The machine of this invention is further characterized by its utilization of braided cable to accomplish both the cutting operation and the sweeping operation, thereby significantly increasing the useful life of both the cutter and the sweeper.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
160 words
A curb and gutter machine used in combination with a vehicle, said machine comprising: a housing assembly attached to the vehicle frame, said housing assembly being adjustable with respect to the vehicle and with respect to the supporting surface along which the vehicle moves; cutter means operatively attached to said housing assembly, said cutter means comprising a cutting head whereby material adjacent the supporting surface may be trimmed; a sweeper means operatively attached to said housing assembly, said sweeper means comprising a brush head whereby material trimmed by said cutting head may be swept; vacuum head means mounted on said housing assembly in receiving relation to material swept from the supporting surface by said sweeper means; and material collection means attached to the vehicle, said vacuum head means being in interconnecting relation between said housing assembly and said material collection means whereby material swept from the supporting surface may pass through said vacuum head means into said material collection means.
Claim 2
Dependent Claim
160 words
A curb and gutter machine used in combination with a vehicle, said machine comprising: a housing assembly attached to the vehicle frame, said housing assembly being adjustable with respect to the vehicle and with respect to the supporting surface along which the vehicle moves; cutter means operatively attached to said housing assembly, said cutter means comprising a cutting head whereby material adjacent the supporting surface may be trimmed; a sweeper means operatively attached to said housing assembly, said sweeper means comprising a brush head whereby material trimmed by said cutting head may be swept; vacuum head means mounted on said housing assembly in receiving relation to material swept from the supporting surface by said sweeper means; and material collection means attached to the vehicle, said vacuum head means being in interconnecting relation between said housing assembly and said material collection means whereby material swept from the supporting surface may pass through said vacuum head means into said material collection means.
Claim 3
Dependent Claim
