Abstract
An apparatus for connection to a periodic, pulsed air supply for providing an indication of time based on receipt of the air pulses comprises a rotor having an externally visible pointer. The rotor is mounted in a cylindrical housing and includes a first section which moves axially of the housing under the force of an air pulse. Teeth are formed on the rotor first section which coact with stationary teeth mounted on the housing interior to force the rotor first section to rotate a predetermined amount. This rotation is transmitted to a second axially stationary rotor section by a keyed connection between the rotor sections. The axially movable section is forced to its original position by a spring mounted in the housing.
