a bearing member or plate 88 a machinery supporting member or housing 86 is arranged or disposed above the bearing member 88 and normally is of such a size that a foot 12 of a machine to be supported thereon will seat or engage the uppermost planar surface thereof supporting member 86 is provided with a centrally disposed threaded aperture 92 for threaded engagement with the externally threaded portion 18 of adjustment member 16 in this manner adjustment member 16 is rotatably engagable with the supporting member 86 the bottom of adjustment member 16 abuts the top surface of the bearing member 88 it will be observed that upon rotation of the adjustment member 16 one can vary the distance between machinery supporting member 86 and the bearing member 88 a locking nut 94 is also provided to fix the adjustment member 16 in place relative to the machinery supporting member 86 upon adjustment of the adjustment member 16 it will be observed from an examination of fig6 and 7 that the machinery supporting member 86 is spaced from the building floor 14 which supports the elastomeric cushion 90 thus any vibrations transmitted through the floor 14 or foundation below the cushion member 90 will be dampened and not fully transmitted to any equipment resting on the machinery supporting member 86 similarly any vibration or impact forces generated by the operation of a machine resting on member 86 will be only partially transmitted to the floor through mount 84 and adjustment member 16 as shown in fig7 located adjacent the adjustment member 16 is a load relieving means.
