Abstract
Abstract A mobile crane rides on rails in a trench. The trench is provided with a pluality of vertical serrations. Pads having mating serrations are provided on the crane. A wedge is movable behind each pad to force the serrations of the pad into engagement with the serrations on the trench. The wedge locks the crane against movement transversely of the rail while the serrations lock the crane against longitudinal movement. Modifications are shown using pins rather than serrations and multiple wedges rather than single wedge and pad.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
194 words
Restraint apparatus for large mobile structures movable along a path and having to be temporarily locked in both the longitudinal and transverse directions in the path, comprising: a mobile structure having rotatable support members, means for supporting the rotatable support members along said path, fixed anchoring means along said path and spaced from a rotatable support member supporting means, and means for wedging and clamping the mobile structure to the fixed anchoring means for positively locking the mobile structure in both the transverse and longitudinal directions, regardless of the position of the mobile structure relative to said supporting means, said wedging and clamping means including a movable main wedge, said anchoring means including a first set of surfaces extending generally transversely of said path, said wedging and clamping means including a second set of generally transversely extending surfaces coupled to said mobile structure and movable into and held in overlapping engagement with said first set of surfaces by movement of said movable main wedge, with the wedge precluding movement of said second set of surfaces laterally of the path and locking means precluding movement of said second set of surfaces longitudinally along said path.
Claim 2
Dependent Claim
194 words
Restraint apparatus for large mobile structures movable along a path and having to be temporarily locked in both the longitudinal and transverse directions in the path, comprising: a mobile structure having rotatable support members, means for supporting the rotatable support members along said path, fixed anchoring means along said path and spaced from a rotatable support member supporting means, and means for wedging and clamping the mobile structure to the fixed anchoring means for positively locking the mobile structure in both the transverse and longitudinal directions, regardless of the position of the mobile structure relative to said supporting means, said wedging and clamping means including a movable main wedge, said anchoring means including a first set of surfaces extending generally transversely of said path, said wedging and clamping means including a second set of generally transversely extending surfaces coupled to said mobile structure and movable into and held in overlapping engagement with said first set of surfaces by movement of said movable main wedge, with the wedge precluding movement of said second set of surfaces laterally of the path and locking means precluding movement of said second set of surfaces longitudinally along said path.
Claim 3
Dependent Claim
36 words
The restraint apparatus of claim 1, said first set of surfaces including vertical serrations spaced along said path, said second set of surfaces including mating vertical serrations engageable, when extended, with said first set of serrations.
Claim 4
Dependent Claim
31 words
The restraint apparatus of claim 1, said first set of surfaces including a transverse opening in said anchoring means, said second set of surfaces including a pin insertable into said opening.
Claim 5
Dependent Claim
78 words
The restraint apparatus of claim 1, said wedging and clamping means including a laterally movable pad, said locking means including guide surfaces fixed against movement relative to said mobile structure in a direction longitudinally of said path, said second set of surfaces being provided on said movable pad, said main wedge being movable between said pad and said mobile structure for extending said pad laterally toward said anchoring means, and means for retracting the main wedge and pad.
Claim 6
Dependent Claim
179 words
The restraint apparatus of claim 1, said mobile structure having a transverse opening formed by longitudinally spaced end walls and a sloped rear wall, said movable main wedge including a slope rear wall engageable with said opening rear wall for laterally extEnding the main wedge when moved along said opening rear wall and an opposite front wall, said second set of generally transversely extending surfaces being provided on the main wedge front wall in confronting relation with said first set of surfaces, movement of said main wedge to extend said second surfaces into locking engagement with said first surfaces causing free longitudinal movement of said main wedge between said opening end walls to allow unrestricted overlapping engagement of said first and second sets of surfaces, said locking means including a set of side wedges insertable between said movable main wedge and said respective end walls of said opening to lock the movable main wedge against longitudinal movement in said opening whereby the movable main wedge prevents lateral movement of said mobile structure and the side wedges prevent longitudinal movement.
Claim 7
Dependent Claim
85 words
The restraint apparatus of claim 1 wherein said anchoring means includes an additional set of opposite, generally transverse surfaces, said wedging and clamping means including an opposite movable main wedge and an additional set of opposite, generally transverse surfaces movable by said opposite movable wedge into overlapping engagement with said additional set of opposite, generally transverse surfaces of said anchoring means to attach to said anchoring means along opposite sides of said rotatable support members to preclude longitudinal and lateral movement of said mobile structure.
Claim 8
Dependent Claim
19 words
The restraint apparatus of claim 6, said anchoring means including an elongated bar between said wedging and clamping means.
Claim 9
Dependent Claim
23 words
The restraint apparatus of claim 6, said anchoring means including a trench having sidewalls on either side of said clamping and wedging means.
Claim 10
Dependent Claim
53 words
The restraint apparatus of claim 5, said first and second sets of generally transverse surfaces including vertical serrations, said movable main wedge also including opposite end walls, each having a vertical keying member, said side wedges each having a mating keying member to slidably position the side wedges aganist the movable main wedge.
Claim 11
Dependent Claim
14 words
The restraint apparatus of claim 9, said main and side wedges being manually positionable.
