Title: Mechanical snubber
Inventor: SALZER HARRY E
IPC: G12B3/08
Filed: 1979-12-22
Granted: 1984-03-16
Abstract: The mechanical, seismic-shock-absorbing snubber for interposition between heavy, relatively movable structures employs, as its damping mechanism, an escapement wheel.  The wheel rotates in response to relative movement of the structures and employs a cooperating, pivoted, pallet member of a predetermined effective mass driven by the escapement wheel into oscillation.  The oscillation of the pallet member, the rate of which is limited by the pallet member's mass and natural period of oscillation, restricts or damps the velocity and acceleration of relative motion between the structures with which the snubber is associated.
