Vibratory roller

Claim 2

In a vibratory roller machine having a roller body and a vibratory system for said roller body, said system comprising two elongated eccentric masses rotatably mounted in said roller body, means for releasably locking said masses in radially angularly adjusted position one with respect to the other and driving means for rotating said two masses as a unit, said roller body having hollow stub axles, one of said eccentric masses consisting of a tubular member having eccentrically disposed tubular stub shafts rotatably mounted within the hollow stub axles of said roller body, the other of said masses consisting of a rod member disposed within said tubular member and having eccentric stub shafts rotatably mounted within the hollow stub shafts of said tubular member, all of said stub axles and stub shafts being coaxial with the axis of rotation of said roller body, said driving means including a driving rotary member secured to one of the stub shafts of only one of said tubular member and rod member and disposed outside said roller body stub axles, said releasable locking means operable on at least one pair of interengaged stub shafts of said tubular member and said rod member so arranged as to adjustably vary the amplitude of vibrations produced in the roller body by rotation of the two eccentric masses as a unit.

Claim 3

In a vibratory roller machine as claimed in claim 1, further including means to releasably lock said tubular member against rotation with respect to said roller body and operable only when said first locking means are released.

Claim 4

In a vibratory roller machine as claimed in claim 1, further including a frame, elongated support members in which the stub axles of said roller body are journaled and having upwardly converging end faces, brackets secured to said frame and providing upwardly converging faces parallel to the faces of said support members and spaced therefrom, and rubberlike blocks inserted between the bracket and support member faces and adhering thereto, to provide a suspension for said roller body which substantially prevents transmission of vibrations from said roller body to said frame.

Claim 5

In a vibratory roller machine as claimed in claim 3, further including means for driving said roller body, said means comprising a pinion journaled in said elongated support member on an axis spaced from the rotary axis of said roller body, said roller body having a crown gear secured thereto at one end thereof and having inwardly directed teeth loosely meshing with said pinion.

Claim 6

In a vibratory roller machine having a roller body and a vibratory system for said roller body, said roller body having hollow stub axles, said system comprising two elongated eccentric masses rotatably mounted within said roller body, means for releasably locking said masses in radially angularly adjusted position one with respect to the other and driving means for rotating said two masses as a unit, one of said eccentric masses consisting of a tubular member having eccentrically disposed tubular stub shafts rotatably mounted within the hollow stub axles of said roller body, the other of said masses consisting of a rod member disposed within said tuBular member and having eccentric stub shafts rotatably mounted within the tubular stub shafts of said tubular member, all of said stub axles and stub shafts being coaxial with the axis of rotation of said roller body, said driving means including a driving rotary member secured to one of the stub shafts of only one of said tubular member and rod member, said locking means including a locking cap mounted for nonrotary but longitudinal movement on one end of a stub shaft of said tubular member, and spring biased into a limit position in which said cap is locked on said rod member to prevent rotation of the latter relative to said tubular member, axial displacement of said cap out of said limit position releasing said cap from engagement with said rod member to allow rotation of said rod member relative to said tubular member, and interengageable means on said locking cap and on the adjacent stub axle of said roller body, interengageable only when said locking cap is displaced out of said limit position, to releasably lock said locking cap and, consequently, said tubular member, against rotation relative to said roller body.

Claim 7

In a vibratory roller machine having a roller body and a vibratory system for said roller body, said roller body having hollow stub axles, said system comprising two elongated eccentric masses rotatably mounted within said roller body, means for releasably locking said masses in radially angularly adjusted position one with respect to the other and driving means for rotating said two masses as a unit, one of said eccentric masses consisting of a tubular member having eccentrically disposed tubular stub shafts rotatably mounted within the hollow stub axles of said roller body, the other of said masses consisting of a rod member disposed within said tuBular member and having eccentric stub shafts rotatably mounted within the tubular stub shafts of said tubular member, all of said stub axles and stub shafts being coaxial with the axis of rotation of said roller body, said driving means including a driving rotary member secured to one of the stub shafts of only one of said tubular member and rod member, said locking means including a locking cap mounted for nonrotary but longitudinal movement on one end of a stub shaft of said tubular member, and spring biased into a limit position in which said cap is locked on said rod member to prevent rotation of the latter relative to said tubular member, axial displacement of said cap out of said limit position releasing said cap from engagement with said rod member to allow rotation of said rod member relative to said tubular member, and interengageable means on said locking cap and on the adjacent stub axle of said roller body, interengageable only when said locking cap is displaced out of said limit position, to releasably lock said locking cap and, consequently, said tubular member, against rotation relative to said roller body.
