A knife insert for use with a knife holder of a grinder, such as a meat grinder, is adapted to be positioned within a slot formed in the knife holder. The knife insert extends outwardly from the outer end of the knife holder, and a beveled edge is formed adjacent the outer end of the knife insert. The beveled edge is adapted to be engaged by a punch, which is struck such as by a hammer to dislodge the knife insert from the knife holder when it is desired to change knife inserts. The beveled edge enables the punch to be held at an angle relative to the knife holder and the adjacent components of the grinder, to allow the punch to easily be held in place. The hammer, which is used to apply the striking force to the punch, can easily be swung clear of the components of the grinder head to facilitate easy and quick removal of the knife insert.
In a grinding apparatus including a knife holder having a slot for receiving a knife insert extending along a longitudinal axis and defining a forward edge extending outwardly of the slot, a rearward edge disposed within the slot, and inner and outer ends, the improvement comprising a beveled edge oriented non-parallel to the longitudinal axis of the knife insert forming at least a part of the outer end of the knife insert, the beveled edge being adapted for engagement by a striking tool having its longitudinal axis oriented non-perpendicular to the longitudinal axis of the knife insert for use in removing the knife insert from the slot, wherein the knife holder defines an outer end onto which the slot opens, and wherein the knife insert extends outwardly of the knife holder outer end when the knife insert is received within the slot, and wherein the beveled edge of the knife insert extends inwardly from the outer end of the knife holder into the slot.
In a grinding apparatus including a knife holder having a slot for receiving a knife insert extending along a longitudinal axis and defining a forward edge extending outwardly of the slot, a rearward edge disposed within the slot, and inner and outer ends, a method of removing the knife insert from the slot, comprising the steps of:
