Abstract
An elevator belt monitoring apparatus includes a housing for receiving an elevator belt and a plurality of blade contacts which are operable to pierce the belt and engage the spaced parallel cords arranged within the belt.

An elevator belt monitoring apparatus, comprising
- (a) a housing for receiving an elevator belt;
- and
- (b) a plurality of belt-piercing contacts arranged in an array within said housing, each belt-piercing contact being configured to contact at least one cord within the belt and having a blade configuration including a top edge, side edges and a bottom edge including at least one projection, said top edge of said belt-piercing contacts containing a receptacle within which a tool may be arranged to force said belt-piercing contacts into the belt a sufficient distance to pierce at least one cord within the belt, said plurality of belt-piercing contacts including a pair of signal contacts having a single projection configured to pierce the cords adjacent to opposite side edges of the belt, respectively, said signal contacts containing an opening for connection with a signal wire.
A belt-piercing contact for an elevator belt monitoring apparatus, comprising
- a blade member having a top edge, a bottom edge, and side edges, said top edge containing a receptacle within which a tool may be arranged to force said belt-piercing contacts into the belt a sufficient distance to pierce at least one cord within the belt and said bottom edge including at least one projection, said at least one projection including an end portion terminating in a point for piercing an elevator belt and a cord arranged in the belt to electrically and mechanically connect said blade member with the cord, said blade member containing an opening for connection with a signal wire.
