Abstract

A novelty for apparently indicating earthquakes, including a circular base marked with concentric circles on its upper side defining different earthquake intensities, a frame upon the base supporting a freely depending electrical contact through a supported circular contact so that in case the device is tilted, the contacts touch and thus close a circuit to a warning alarm.

Claims

1. An earthquake indicator, comprising in combination, a circular base, an inverted U-shaped frame affixed on said base, a circular ring supported by strips underneath said frame, and a depending rod from said frame, passing through said ring, said rod and ring comprising contacts of a switch in a warning electric circuit, a plurality of circles marked upon said base defining earthquake intensities, and means to adjust said indicator.

2. The combination as set forth in claim 1 wherein said means comprises said ring being pivotaly mounted on said strips.

3. The combination of claim 2 wherein said means further includes a base which is pivotaly mounted on said frame.
