Abstract
Abstract A soil compacting machine comprising three interarticulated units, two of which are interconnected for universal relative swinging movement about three orthogonal axes, with hydraulic power means for effecting the swinging about at least two of these axes. The swinging between the other two units is also powered, the drive to the connections between the units being alternative so that when one pair of units is being swung relative to each other the other pair will idle, and vice versa.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
83 words
A multiple machine for compacting soil and the like, comprising three compacting units interconnected by steering articulated joints, at least one of said joints interconnecting the two adjacent units for rotation relative to each other about three orthogonal axes, and power means for selectively controlling the swinging of said two units relative to each other about at least two of said three orthogonal axes thereby to permit control by an operator of the position of said two adjacent units relative to each other.
Claim 2
Dependent Claim
83 words
A multiple machine for compacting soil and the like, comprising three compacting units interconnected by steering articulated joints, at least one of said joints interconnecting the two adjacent units for rotation relative to each other about three orthogonal axes, and power means for selectively controlling the swinging of said two units relative to each other about at least two of said three orthogonal axes thereby to permit control by an operator of the position of said two adjacent units relative to each other.
Claim 3
Dependent Claim
45 words
A machine as claimed in claim 1, and power means for swinging the other two units relative to each other about at least a vertical axis, and means for selectively actuating the power means associated with only one pair of said units at a time.
Claim 4
Dependent Claim
40 words
A machine as claimed in claim 1, said power means comprising means for selectively swinging said two units relative to each other about a vertical axis and about a horizontal axis transverse to the path of movement of said machine.
Claim 5
Dependent Claim
105 words
A machine as claimed in claim 1, the connection of said two units for rotation about said three orthogonal axes comprising an upright body mounted for rotation about a vertical axis on one of said units, a cylindrical body mounted on said upright body for vertical swinging movement about a first horizontal axis passing through said vertical axis, and means secured to the other said unit of said two units and rotatable on and relative to said cylindrical body about a second horizontal axis coaxial with said cylindrical body and perpendicular to said first horizontal axis and perpendicular to and passing through said vertical axis.
Claim 6
Dependent Claim
18 words
A machine as claimed in claim 4, said second horizontal axis being disposed above said first horizontal axis.
Claim 7
Dependent Claim
66 words
A machine as claimed in claim 4, said cylindrical body encompassing said means on said other unit, a hydraulic jack interconnecting said cylindrical body and said one unit to swing said two units relative to each other about said vertical axis, and a hydraulic jack interconnecting said cylindrical body and said upright body to swing said units relative to each other about said first horizontal axis.
Claim 8
Dependent Claim
35 words
A machine as claimed in claim 4, and latch means selectively engageable between said cylindrical body and said other unit to prevent rotation of said units relative to each other about said second horizontal axis.
