The Wall Motion Picture Camera
The Wall camera (Fig. 5) was originally developed in 1926 and 1927 for newsreel work and has recently been redesigned for use either in the studio or in the field. The camera can be equipped with either light-valve, flashing lamp, or galvanometer. It is driven by a direct-drive, 12-volt, dc. motor of approximately l/20 hp. The motor can be of the interlocking type, if desired, to run with a 12-volt motor of the same type upon a sound recorder. The camera can also be furnished with a synchronous motor for synchronizing with a sound recorder, if desired. Each motor has but one bearing fitted at the outer end of the armature shaft. The inner end of the armature shaft is direct coupled to the shutter shaft, providing a direct form of drive. The outer end of the shutter shaft constitutes the inner bearing for the armature shaft.
