ABSTRACT:
Vibration sensing and responding apparatus which includes a concave spherical surface and a ball disposed on said surface. Spring loaded means extends through said surface and is retained in position by said ball. Should the ball be displaced by horizontal vibration of the surface or be displaced by a mechanism responding to vertical vibration, the spring loaded means will move upwardly and in so doing actuate a device coupled thereto.
