I | Intermittent Movement -[ FAFM '24 ]-

A crucial component of a 35mm motion picture projector, an intermittent movement performs the task of shuttling the film one frame at at time, then holding the frame absolutely still while the projector shutter allows light to be sent through the film and on the way to the screen, all in the span of 1/24th of a second.

 

Housed in this device's midsection is a Geneva cross (or Maltese Cross) mechanism which runs in an oil bath. This intermittent relies on an oil feed from the projector's recirculating lubrication system; others usually hold a supply of oil which must be maintained at a safe level and changed occasionally.
