Abstract

5929. Marks, E. C. R., [Hutchings, G. B.]. April 20. Moving and changing apparatus.-Relates to display apparatus for producing motion picture or sign effects, of the type comprising a box containing a screen member and a composite picture member, the screen member having opaque portions with clear spaces between, and the two members having relative movement to display the different parts of the composite picture member at different times through the clear spaces of the screen member. The screen member 1 is supported on a rest 3, 3', and the picture member 2 on a device 4, 41 having guides 5, whereby it may be quickly removed and replaced through an opening in the box. Both of the members may be so removed and replaced. The rest 3, 3<1> is suspended by links 6, 7, whereby the screen member 1 can be moved laterally a small distance. The means for oscillating the member 1 comprise a rod 11 carrying pins 14, whereby it is operated by a heart-shaped cam 13 driven by a train of gear-wheels 21. The member 1 can be adjusted to bring it into exact register with the picture member 2 by raising and lowering the link 6, this being effected by a screw 14<h> which, when turned, moves a sliding block 14<a> from which the link 6 hangs.
