Continuous motion picture projector apparatus

A continuous motion picture projection apparatus comprising:

• a. an elongated strip of film having imprinted thereon in a side by side relationship along substantially its entire length first and second image tracks each comprising a series of sequential photographic images;
• b. illumination means disposed on one side of said strip of film including a light source and first optical means for receiving rays of light from said light source and passing them through the photographic images on the film, said illumination means being movable relative to said film from a first position in alignment with said first image track to a second position in alignment with said second image track;
• c. projection means disposed on the opposite side of said film strip for receiving the rays of light passing through the film and projecting them onto a screen, said projection means being movable relative to said film from a first position in alignment with said first image track to a second position in alignment with said second image track;
• d. drive means for moving said strip of film between said first optical means and said projection means in a first direction and then in a second direction said driving means comprising:
• 1. a rotatable drive shaft;
• 2. reversible motor means for rotatably driving said drive shaft;
• 3. film feed means operably coupled with said drive shaft and adapted to engage said film to move it between said first optical means and said projection means;
• and
• 4. first and second film carrying reel means driven by said drive shaft for alternately reeling in and reeling out said strip of film relative to said film feed means;
• e. reversing means operatively associated with said drive means and said film strip for sensing an indicating point on said film and thereupon reversing said drive means to reverse the direction of travel of said film;
• f. first means operatively coupled with said drive means and said illumination means for moving said illumination means alternately between its first and second positions upon reversal of said drive means, said first means comprising a first friction clutch means operably coupled with said drive shaft and interconnecting said drive shaft with said illumination means for moving the latter alternately between the first and second positions upon a reversal of the direction of rotation of said shaft;
• and
• g. second means operatively coupled with said drive means and said projection means for moving said projection means alternately between its first and second positions upon reversal of said drive means, said second means comprising a second friction clutch means operably coupled with said drive shaft and interconnecting said drive shaft with said projection means for moving the latter alternately between the first and second positions upon a reversal of the direction of rotation of the shaft.
