Rectangular notice used on an incline at Dinorwig Quarry. The notice informed quarry staff of the signalling method used on the inclines - when a bell rang once it meant that the incline was stopping; when a bell rang twice it meant that the incline was starting.

Dinorwig Quarry had a series of inclines - inclines were an inventive, cost effective way of transporting slate down the mountain. It worked on a very simple principle - loaded wagons would travel down the incline, and their weight would haul empty wagons back up to the quarry using the force of gravity. Dinorwig Quarry had four main series of inclines - the ‘A’ inclines (operating from the Gilfach Ddu to the ‘Garret’ section of the quarry); the ‘B’ inclines (mainly ‘tank’ inclines situated in the middle section of the quarry); the ‘C’ inclines (operating from the ‘Hafod Owen’ section to the ‘Braich’ section of the quarry); and the ‘V’ inclines (operating at Vivian Quarry).

This notice was used on the ‘A’ series of inclines.
