Abstract
A motion picture film shipping and handling system is adaptable for use on either a platter-type movie projector system or on a reel-type movie projector system. The system includes two film supporting flanges with a collapsible hub located therebetween. A central supporting hub is releasably connected to the collapsible hub, and fasteners releasably attach the elements together. A shipping case contains the flanges and the film in a manner which dissipates impact forces to protect the film and the flanges.

A motion picture film shipping and handling system comprising:
- A) a case which includes
- (1) two substantially identical case half sections, with each half section having
- (a) an annular outer wall having an inner and an outer diameter,
- (b) an annular inner wall having an inner and an outer diameter,
- (c) an annular central wall connected to said inner wall and to said outer wall,
- (d) a hub section connected to said inner wall,
- (2) said inner and outer walls and said central wall of one half section contacting, respectively, the inner and outer walls and the central when one case half section is in contact with the other case half section,
- (3) a case closing means for holding said case half sections together, and
- (4) a plurality of shipping screws threadably mounted on each of said case sections near said hub section of each case section;
- B) a film supporting means accommodated in said case and which includes
- (1) two annular flanges, each flange having
- (a) a central opening with an inner diameter sized so said case inner wall slidably fits into said flange central opening, and
- (b) an outer edge with an outer diameter sized so said annular flange fits snugly against said case outer wall,
- (2) an annular locking ring having an outer surface with an outer diameter greater than the flange central opening inner diameter,
- (3) fastening means releasably connecting said locking ring to each of said flanges,
- (4) a shipping means mounted on said locking ring outer surface, and
- (5) an annular film winding ring which surrounds said locking ring, said film winding ring being resiliently biased towards said locking ring and having an inner surface and an outer surface, said shipping means being located between said film winding ring inner surface and said locking ring outer surface, said shipping means moving from a locking position biasing said film winding ring radially outward away from said locking ring outer surface to an unlocking position permitting said film winding ring to move towards said locking ring outer surface;
- and
- C) hub means for attaching said film supporting means to a spindle, said hub means including
- (1) a center hub element located adjacent to said annular locking ring central opening and having means for releasably mounting said center hub element to the spindle, and
- (2) fastening means releasably mounting said center hub element to said film supporting means.
