Leveler for paving machine

Claim 2

A leveling attachment for pavers and the like, said attachment comprising a top member having a forward edge and a rear edge, a front wall depending from said member adjacent the forward edge thereof, means pivotally securing said front wall to said member for forward and rearward swinging movement, means limiting the forward swinging movement of the front wall, a rear wall depending from said top member generally parallel to said front wall, biasing means resiliently resisting rearward swinging of the front wall, said biasing means comprising enlarged coil compression springs engaged between said front and rear walls, and mounting means for mounting said top member on a paver in a manner whereby said front wall depends into engagement with the ground forward of the paver to define a clear path therefor.

Claim 3

The attachment of claim 1 including an upper edge on said front wall engageable with the top member upon a forward swinging of said front wall beyond a predetermined point, said upper edge constituting the means for limiting the forward swinging of the front wall.

Claim 4

The attachment of claim 1 wherein said front wall includes a vertically adjustable lower plate.

Claim 5

The attachment of claim 1 wherein said front wall is transversely angled to effect a laterally inward directing of encountered material out of the path of the traveling support means of the vehicle.

Claim 6

The attachment of claim 1 wherein said front wall is transversely angled to effect a laterally inward directing of encountered material out of the path of the paver, said front wall including a vertically adjustable lower plate.

Claim 7

In combination with a paver or the like incorporating traveling support means along the opposed sides thereof, a leveling attachment mounted forward of each of said traveling support means, each attachment including a first depending wall generally vertically orientated and angled inwardly transversely across the path of the corresponding traveling support and toward the center of the paver, means pivotally mounting said first depending wall for forward and rearward swinging movement, means limiting the forWard swinging of said first depending wall, a second depending wall disposed rearwardly of said first depending wall, and biasing means resiliently resisting rearward swinging of said first depending wall, said biasing means comprising enlarged coil compression springs engaged between said first and second depending walls.

Claim 8

In combination with a paver or the like incorporating traveling support means along the opposed sides thereof, a leveling attachment mounted forward of each of said traveling support means, each attachment including a first depending wall generally vertically orientated and angled inwardly transversely across the path of the corresponding traveling support and toward the center of the paver, means pivotally mounting said first depending wall for forward and rearward swinging movement, means limiting the forWard swinging of said first depending wall, a second depending wall disposed rearwardly of said first depending wall, and biasing means resiliently resisting rearward swinging of said first depending wall, said biasing means comprising enlarged coil compression springs engaged between said first and second depending walls.

Claim 9

The construction of claim 6 wherein said front wall is vertically adjustable.

Claim 10

A leveling attachment for pavers and the like, said attachment comprising a top member having a forward edge and a rear edge, a front wall depending from said member adjacent the forward edge thereof and transversely angled to effect a laterally inward directing of encountered material out of the path of the paver, said front wall including a vertically adjustable lower plate, means pivotally securing said front wall to said member for forward and rearward swinging movement, means limiting the forward swinging movement of the front wall, said limiting means comprising an upper edge on said front wall engageable with the top member upon a forward swinging of said front wall beyond a predetermined point, a rear wall depending from said top member generally parallel to said front wall, biasing means resiliently resisting rearward swinging of the front wall, said biasing means comprising enlarged coil compression springs engaged between said front and rear walls, and mounting means for mounting said top member on a paver in a manner whereby said front wall depends into engagement with the ground forward of the paver to define a clear path therefor.

Claim 11

A leveling attachment for pavers and the like, said attachment comprising a top member having a forward edge and a rear edge, a front wall depending from said member adjacent the forward edge thereof and transversely angled to effect a laterally inward directing of encountered material out of the path of the paver, said front wall including a vertically adjustable lower plate, means pivotally securing said front wall to said member for forward and rearward swinging movement, means limiting the forward swinging movement of the front wall, said limiting means comprising an upper edge on said front wall engageable with the top member upon a forward swinging of said front wall beyond a predetermined point, a rear wall depending from said top member generally parallel to said front wall, biasing means resiliently resisting rearward swinging of the front wall, said biasing means comprising enlarged coil compression springs engaged between said front and rear walls, and mounting means for mounting said top member on a paver in a manner whereby said front wall depends into engagement with the ground forward of the paver to define a clear path therefor.
