A servant bell or service bell is a bell used to call the attention of an in-house servant.
In the 18th century, British country houses grew in size and servants were moved to separate service wings. Servants were further moved out of sight with the use of service tunnels, basement walkways and utility rooms. With this followed a need for new methods of communication.
Rooms were fitted with bell pulls or levers which a household member could pull. A system of wires connected the pull to a bell in a service area, in stairwells, outside servants' quarters, or in servants' rooms.
The bells were fixed to a board and each bell was individually labelled so servants could see which room requested service.
Bells hung from coiled springs. A pendulum connected to the spring continued to swing so servants could see which bell had rung. Bells could be of different sizes and emit different sounds, allowing servants to audibly identify specific bells.
How quickly the bells were answered was often a matter of complaint.
Marilyn Palmer commented, "No object is more evocative of historic household communication than the sprung bell."
