Adjustable timing mechanism for shrimp processing machine cutter assembly

The invention generally relates to mechanical timing mechanisms and, more particularly, relates to timing mechanisms for shrimp processing machines. A timing mechanism for a shrimp processing machine including a cam wheel having a recess therein adapted to receive an end of a cutter bar to which a cutting blade is rotatably mounted. Rotation of the cam wheel causes the cutter bar, and the cutting blade to move. The cutter bar and blade are positioned proximate a main gear wheel to which shrimp are mounted, such that movement of the cutter bar and cutting blade causes the cuts to be placed into each shrimp. The timing mechanism includes mating gear teeth on the cam wheel and indexing gear mounted proximate the cam wheel. The cam wheel and indexing gear are held into engagement by the biasing force of a spring. The indexing gear may be disengaged from the cam wheel to allow the cam wheel to be rotated to change the timing of the cutting blade.
