ABSTRACT:
A chime alarm apparatus having a housing having an axis and adapted to be suspended from rigid support. A first elongate annular member having upper and lower ends is suspended at its upper end from the housing and is substantially coaxial therewith, whereby the member may swing laterally relative to the housing. A disc-shaped contact member is supported by the first elongate member intermediate the ends thereof and the lower end of the first elongate member includes a pendant whereby the first elongate member may be caused to move laterally by an external force contacting the pendant. A plurality of second elongate members are suspended from the housing peripherally outwardly of and spaced a selected distance from the first elongate member and the contact member. Each second member has an area of contact between its ends, the pendant being normally below the lower ends of the second members. The disc-shaped contact member and the second members are of a material whereby a chime sound is produced when the contact member moves laterally and contacts the area of contact of at least one of the second members. An electric circuit includes a source of power, the contact member, at least each area of contact of the second members and alarm, whereby when the contact member contacts an area of contact of at least one second member, the electric circuit is closed and the alarm in the electric circuit is activated.
