Title: Self releasing clamp for cine film joining machine - opens on return stroke of movement needed to make joint
Inventor: SCHROEDER ROLF ING GRAD
IPC: G03D15/04
Filed: 1975-04-11
Abstract: After the film had been placed in position, the toggle (3) was pressed down to hold it (at 3b). This made the spring (9) tip the bird-shaped lever until its beak (7a) was on the same horizontal level as a fixed stop (8c), but at that stage in front of it. A spring-loaded peg (4) was moved across a nose (to 2d) to hold the clamp latched. The clamp was then moved back and forth as required for fastening the joint. This left the beak behind the stop, as illustrated. Now, as the clamp continues to move, the bird lever is held back by the stop. Eventually a peg (7c) on the bird's head will be brought against the toggle and will tip it over, releasing the clamp from the film. The toggle, in tipping, will strike the bird's tail (7d), returning that lever to its starting position, and it will also release the latch (4).
