Abstract
A powered shrimp deveining assembly includes a motor coupled to an output and a secondary shaft both housed in a removable enclosure, the output shaft and the secondary shaft extending through an adapter to turn a cutter against the rotation of a pair of guide disks. The adapter is provided with a boss in which one end of a bell crank is engaged, the other end of the bell crank extends in a threaded projection through an arcuate slot formed in a cover that is mounted on the adapter to shield the cutting mechanism. An idler roller on the bell crank is thus pivotally spaced from the guide disks to direct shrimp bodies against the cutter, the same bell crank fixing mechanism also retaining the cover in place.

In a powered shrimp deveining apparatus, characterized by a source of rotary power provided with an output shaft, said source being mounted in a housing including an end wall perforated to receive said output shaft, and a rotary cutter mounted on said output shaft external to said housing, the improvement comprising:
- a frame structure mounted in the housing and engaged to the source of rotary power, said frame structure including a first bearing means for supporting the output shaft, a second bearing means for supporting a secondary shaft, said second bearing means aligned in parallel with said first bearing means, said secondary shaft extending through the end wall adjacent the output shaft;
- pulley means interconnected between the output shaft and said secondary shaft, said pulley means located exterior to said frame structure and distal to said end wall;
- a generally circular adapter mounted on the end wall, said adapter mounted exterior to the housing, said adapter including a peripheral bead and a boss within the periphery of said bead aligned adjacent said output and secondary shafts;
- a bell crank having a first and second end and pivoted at said first end in said boss, said bell crank including an idler roller on said second end, said second end of said bell crank extending in a threaded projection beyond said roller;
- a generally hollow cover provided with a skirt conformed for engaging fit with said peripheral bead, said cover including an arcuate slot conforming in the dimensions thereof with the pivotal motion of said threaded projection;
- and
- engaging means selectively engageable to said threaded projection external of said cover upon the engagement of said skirt with said peripheral bead.
A rotary cutting apparatus comprising:
- means for coupling a source of rotary power to an output shaft;
- a housing including an end wall perforated to receive said output shaft;
- a rotary cutter mounted on said output shaft external to said housing;
- a frame structure mounted in said housing, said frame structure including a first bearing means for supporting said output shaft, a second bearing means for supporting a secondary shaft, said second bearing means aligned in parallel with said first bearing means, said secondary shaft extending through said end wall adjacent said output shaft;
- coupling means interconnected between said output shaft and said secondary shaft, said coupling means located exterior to said frame structure and distal to said end wall;
- a generally circular adapter mounted on said end wall, said adapter mounted exterior to said housing, said adapter including a peripheral bead and a boss within a periphery of said bead aligned adjacent said output and secondary shafts;
- a bell crank having a first and second end and pivoted at said first end in said boss, said bell crank including an idler roller on said second end, said second end of said bell crank extending in a threaded projection beyond said roller;
- a generally hollow cover provided with a skirt conformed for engaging fit with said peripheral bead, said cover including an arcuate slot conforming in the dimensions thereof with the pivotal motion of said threaded projection;
- and
- engaging means selectively engageable to said threaded projection external of said cover upon the engagement of said skirt with said peripheral bead.
A deveiner attachment for a food processor, the food processor including a vertical output shaft for delivering rotary motion, said attachment comprising:
- means for coupling the vertical output shaft to an output shaft;
- a housing including an end wall perforated to receive said output shaft;
- a rotary cutter mounted on said output shaft external to said housing;
- a frame structure mounted in said housing, said frame structure including a first bearing means for supporting said output shaft, a second bearing means for supporting a secondary shaft, said second bearing means aligned in parallel with said first bearing means, said secondary shaft extending through said end wall adjacent said output shaft;
- coupling means interconnected between said output shaft and said secondary shaft, said coupling means located exterior to said frame structure and distal to said end wall;
- a generally circular adapter mounted on said end wall, said adapter mounted exterior to said housing, said adapter including a peripheral bead and a boss within a periphery of said bead aligned adjacent said output and secondary shafts;
- a bell crank having a first and second end and pivoted at said first end in said boss, said bell crank including an idler roller on said second end, said second end of said bell crank extending in a threaded projection beyond said roller;
- a generally hollow cover provided with a skirt conformed for engaging fit with said peripheral bead, said cover including an arcuate slot conforming in the dimensions thereof with the pivotal motion of said threaded projection;
- and
- engaging means selectively engageable to said threaded projection external of said cover upon the engagement of said skirt with said peripheral bead.
