Abstract
A double plate retrofit assembly for a meat grinder includes a centering pin adapted for insertion into a longitudinal bore provided in the feed screw of the meat grinder. Primary and secondary knife holder assemblies are adapted for mounting to the centering pin, and primary and secondary orifice plates are mounted adjacent the primary and secondary knife holder assemblies, respectively. Adapter mounting rings are employed for affixing the orifice plates to the end of the meat grinder. A spring washer mechanism is disposed adjacent each knife holder assembly for biasing the knife holder assemblies against the orifice plates to improve grinding performance. The amount of bias provided by the spring washers is adjustable by adjusting the position of the mounting rings.

A double plate retrofit assembly for a meat grinder or the like, said grinder having a rotatable feed screw to which one of more first cutting elements are mounted adjacent an end thereof, said end of said feed screw having a substantially central longitudinal bore defined by one or more inner walls, said bore extending throughout a portion of the length of said feed screw, said first cutting elements being disposed adjacent a first orifice plate, said double plate retrofit assembly comprising:
- a second orifice plate adapted for mounting downstream of said first orifice plate and spaced therefrom;
- one or more second cutting elements disposed adjacent said second orifice plate and downstream of said first orifice plate;
- mounting pin means having a portion adapted for insertion into said longitudinally extending bore provided in said feed screw and a portion projecting from the end of said feed screw, said portion of said mounting pin means adapted for insertion into said bore being not engaged with the one or more inner walls defining said bore, said projecting portion of said mounting pin means being adapted to receive said one or more first cutting elements and said one or more second cutting elements for mounting said cutting elements thereto;
- and
- drive means disposed between said feed screw and the portion of said mounting pin means projecting from the end of said feed screw for rotatably driving said mounting pin means and said one or more first and second cutting elements in response to rotation of said feed screw.
An assembly for grinding meat or the like, comprising:
- a feed screw housing having a discharge end;
- a rotatably driven feed screw disposed within said housing and having an end adjacent the discharge end of said feed screw housing, with said end of said feed screw having a substantially central bore defined by one or more inner walls, said bore extending longitudinally throughout a portion of the length of said feed screw;
- a mounting pin having a portion disposed within the longitudinal bore of said feed screw and a portion projecting therefrom, said portion disposed within the bore of said feed screw being not engaged with the one or more inner walls defining said bore;
- a first orifice plate disposed at the discharge end of said feed screw housing;
- first rotatable cutting means mounted to said mounting pin and disposed adjacent said first orifice plate;
- a second orifice plate mounted downstream of said first orifice plate;
- second rotatable cutting means mounted to said mounting pin and disposed downstream of said first cutting means and adjacent said second orifice plate;
- and
- drive means disposed between said feed screw and the portion of said mounting pin projecting from the end of said feed screw for rotatably driving said mounting pin and said first and second cutting means in response to rotation of said feed screw.
A double plate retrofit assembly for a meat grinder of the like, said grinder having a rotatable feed screw to which one or more first cutting elements are mounted adjacent an end thereof, said end of said feed screw having a substantially central longitudinal bore extending throughout a portion of the length of said feed screw, said first cutting elements being disposed adjacent a first orifice plate, said double plate retrofit assembly comprising:
- a second orifice plate adapted for mounting downstream of said first orifice plate and spaced therefrom;
- one or more second cutting elements disposed adjacent said second orifice plate and downstream of said first orifice plate;
- mounting pin means having a portion adapted for insertion into said longitudinally extending bore provided in said feed screw and a portion projection from the end of said feed screw, said projecting portion of said mounting pin means being adapted to mount said one or more first cutting elements and said one or more second cutting elements;
- means disposed between said one or more first cutting elements and said feed screw for rotatably driving said one or more first cutting elements in response to rotation of said feed screw;
- pin drive means disposed between said one or more first cutting elements and said mounting pin means for directly rotatably driving said mounting pin means solely in response to rotation of said one or more first cutting elements;
- and
- means for rotatably driving said one or more second cutting elements in response to rotation of said one or more first cutting elements.
An assembly for grinding meat or the like, comprising:
- a feed screw housing having a discharge end;
- a rotatably driven feed screw disposed within said housing and having an end adjacent the discharge end of said feed screw housing, with said end of said feed screw having a substantially central bores extending longitudinally throughout a portion of the length of said feed screw;
- a mounting pin having a portion disposed within the longitudinal bore of said feed screw and a portion projecting therefrom;
- a first orifice plate disposed at the discharge end of said feed screw housing;
- first rotatable cutting means mounted to said mounting pin and disposed adjacent said first orifice plate, said first rotatable cutting means being rotatably driven in response to rotation of said feed screw;
- a second orifice plate mounted downstream of said first orifice plate;
- second rotatable cutting means mounted to said mounting pin and disposeds downstream of said first cutting means and adjacent said second orifice plate;
- pin drive means disposed between said first rotatable cutting means and said mounting pin for directly rotatably driving said mounting pin solely in response to rotation of said first rotatable cutting means;
- and
- means for rotatably driving said second rotatable cutting means in response to rotation of said first rotatable cutting means.
