Apparatus Developed to Simplify Manufacture of Lens Wheels for Continuous Projectors

Arthur J. Holman

The continuous projector described briefly in Volume XII, Number 36, of the Transactions under the classification, “Symposium on New Motion Picture Apparatus,” is essentially a precise optical instrument requiring a higher degree of accuracy in manufacture than is customary in optical work. The lens wheels, shown in position in the mechanism (Fig. 1), are the essential and characteristic elements of this projector. In order that the screen image may possess the critical definition and the steadiness essential to good projection and may also have, to the fullest extent, the peculiarly pleasing qualities this system of projection is capable of producing, it is essential that the lens wheels be accurate.
