Abstract
In collating packaging equipment and the like, a novel flight that comprises a flight body including at least one spring loaded arm that engages the conveyor drive chain to allow rapid and simplified interchangeability of flight arrangements, i.e. pitch or pocket size, without the need for disassembly and re-assembly of the entire flight drive mechanism.
Claims16
A flight for use in collating packaging equipment and the like comprising:
- A) a flight body having first and second extremities;
- B) a spring mounted in at least one of said extremities;
- C) a first arm attached to said spring and extending from said flight body;
- D) a first chain drive engagement pin attached to said first arm and extending in the direction of said flight body;
- E) a second arm extending from the other of said extremities;
- and
- F) a second chain drive engagement pin attached to said second arm;
- said first arm and said spring connected such that when said first arm is drawn away from said first or second extremity said spring acts to draw said first arm and said attached first chain drive engagement pin and said second arm and said second chain drive engagement pin back toward said flight body.

In combination a flight and drive chain comprising:
- A) a flight body having first and second extremities;
- B) a spring mounted in at least one of said extremities;
- C) a first arm attached to said spring and extending from said flight body;
- D) a first chain drive engagement pin attached to said arm and extending in the direction of said flight body;
