Earthquake isolating support
First Claim
1. In apparatus to isolate an object or structure from earthquake motion, and support it on a floor surface the combination comprising:
- (a) rollable bearing means supporting one of said object or structure for lateral motion generally parallel to a support, and(b) other means including a bowl element and a roller element which are interengaged to yieldably resist said lateral movement of the structure, said bowl element defining a bowl-shaped surface having an upright axis, and the roller element comprising a ball urged into engagement with said surface to exert lateral load on one of the object and structure when the ball engages the bowl surface in laterally spaced relation to the bowl axis, one of the elements carried by said one of the object and structure to move laterally therewith and the other element carried by the support,(c) said rollable bearing means laterally spaced from said other means including said bowl shaped surface and ball, said rollable bearing means including multiple floor engaging bearings extending at the same level below the level of the bowl-shaped surface.

Abstract
Apparatus to isolate an object or equipment from earthquake motion comprises:
(a) rollable bearing means supporting such structure for lateral motion generally parallel to a support;
(b) and other means including interengaged bowl and roller elements to yieldably resist such lateral movement of the structure.
Typically, the bowl element defines a bowl-shaped surface having an upright axis, and the roller element comprises a ball urged into engagement with that surface to exert lateral load on the object or equipment when the ball engages the bowl surface in laterally spaced relation to the bowl axis, one of the elements carried by the object or equipment to move laterally therewith and the other element carried by the support.
