Maker and Role
Wooden box with rectangular glass window on top surface, black, with eight circular clear holes to see 'drops' below. Properly called a ‘Semaphore Gravity Drop Annunciator', a bell was mounted on a board above the box containing the ‘drops’. The annunciator, which was battery operated, could be activated by any one of four push buttons, each in a different locality. One push on a button would cause one disc or target to drop as well as ring the bell. The drops are restored to the ‘normal’ position by pushing the rod on the right hand side of the box. The annunciator was commonly used as paging indicators in servants quarters, (this one was probably used in a large house),or as fire alarms. Larger devices were used in hotels and rail stations.
