Abstract
Abstract A damping body composed of two substantially parallel, oppositely situated support surfaces for supporting a machine mounting base or foundation frame and for contact with a machine pedestal or socket arrangement. To obtain a uniform damping of sound and vibrations and to achieve a certain leveling of the machine mounting base, the damping body comprises at least two substantially wedge-shaped partial bodies which, in their unloaded state, can be shifted relative to one another along parting surfaces which are not in parallelism with the support surfaces. The damping body may be particularly advantageously employed for mounting elevator drive machines or the like.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
131 words
A damping body for machine support arrangements comprising: at least two superimposed substantially wedge-shaped partial bodies formed of elastic damping material and defining two substantially parallel and mutually oppositely situated support surfaces respectively serving for supporting a machine mount base and bearing upon a machine pedestal; said wedge-shaped partial bodies containing separation surfaces, dispositioned in nonparallel relationship with respect to said support surfaces; said wedge-shaped partial bodies being shiftable relative to one another along said separation surfaces in the unloaded condition of said damping body; and at least one of said partial bodies being provided with a metallic plate member embedded in said elastic damping material in a position substantially parallel to said support surfaces defined by said wedge-shaped partial bodies of the damping body, to dampen or reflect sonic energy.
Claim 2
Dependent Claim
131 words
A damping body for machine support arrangements comprising: at least two superimposed substantially wedge-shaped partial bodies formed of elastic damping material and defining two substantially parallel and mutually oppositely situated support surfaces respectively serving for supporting a machine mount base and bearing upon a machine pedestal; said wedge-shaped partial bodies containing separation surfaces, dispositioned in nonparallel relationship with respect to said support surfaces; said wedge-shaped partial bodies being shiftable relative to one another along said separation surfaces in the unloaded condition of said damping body; and at least one of said partial bodies being provided with a metallic plate member embedded in said elastic damping material in a position substantially parallel to said support surfaces defined by said wedge-shaped partial bodies of the damping body, to dampen or reflect sonic energy.
Claim 3
Dependent Claim
51 words
The damping body as defined in claim 1, wherein: each separation surface of the related substantially wedge-shaped partial body possesses parallel rib means extending transversely with respect to the direction of displacement of the relatively shiftable partial bodies; and said rib means positively interengaging said wedge-shaped partial bodies with one another.
Claim 4
Dependent Claim
21 words
The damping body as defined in claim 1, wherein: said substantially wedge-shaped partial bodies are essentially identical in shape and size.
