Abstract

A food product slicer with a rotatable slicer knife includes a ring guard disposed about a portion of the peripheral cutting edge of the slicer knife. A removable ring guard cover includes a food catching wall positioned in the gap between the peripheral cutting edge of the knife and the ring guard.

Claims

1. A slicer for use in slicing a food product, the slicer comprising:

a slicer body;

a circular slicer knife mounted for rotation relative to the slicer body, the slicer knife having a peripheral cutting edge;

a carriage mounted for moving food product back and forth past the circular slicer knife;

a ring guard disposed about the peripheral cutting edge along at least a portion of a non-cutting zone of the circular slice knife, a gap between ring guard and the peripheral cutting edge;

a ring guard cover including a food catching wall positioned in the gap for catching food product thrown off the circular slicer knife toward the ring guard, the ring guard cover removable for cleaning,

wherein the ring guard cover is removable by movement in a direction outward from the slicer body and away from the ring guard while the ring guard remains in place.

2. The slicer of claim 1 wherein an upper portion of the non-cutting zone has a knife sharpening assembly located therealong, the food catching wall includes an upper portion positioned in a gap between the knife sharpening assembly and the peripheral cutting edge.

3. The slicer of claim 2 wherein a movable knife guard member is positioned adjacent the peripheral cutting edge of the knife proximate to the knife sharpening assembly, the upper portion of the food catching wall positioned between the movable knife guard member and the peripheral cutting edge.

4. The slicer of claim 2 wherein the ring guard has a rectangular cross-section, the ring guard cover has a u-shaped cross section in a region where it aligns with the ring guard, the ring guard cover has an L-shaped cross-section in a region where it aligns with the knife sharpening assembly.

5. The slicer of claim 1 wherein the ring guard cover is integrated into a cover plate that is positioned over an outwardly facing surface portion of the knife, the food catching wall extends from an interior side of the cover plate into the gap, an exterior side of the cover plate includes a food product slide face.

6. The slicer of claim 1 wherein a cover plate is positioned over at least portions of the ring guard cover, an exterior side of the cover plate includes a food product slide face, the cover plate aids in holding the ring guard cover in place and is removable.

7. The slicer of c1aim 1 wherein:

the ring guard includes a first portion aligned with the knife edge and located radially exterior the food catching wall and a surface portion facing outward from the slicer body;

the ring guard cover includes an overlaying portion extending radially outward from the food catching wall over and adjacent to the surface portion of the ring guard.

8. A slicer for use in slicing a food product, the slicer comprising:

a slicer body;

a circular slicer knife mounted for rotation relative to the slicer body, the slicer knife having a peripheral cutting edge;

a carriage mounted for moving food product back and forth past the circular slicer knife;

a ring guard disposed about the peripheral cutting edge along at least a portion of a non-cutting zone of the circular slice knife, a gap between ring guard and the peripheral cutting edge;

a ring guard cover including a food catching wall positioned in the gap for catching food product thrown off the circular slicer knife toward the ring guard, the ring guard cover removable for cleaning,

wherein the ring guard includes a surface portion offset from and substantially coplanar with a plane defined by the peripheral cutting edge, the ring guard cover includes an overlaying portion adjacent the surface portion.

9. The slicer of claim 8 wherein the overlaying portion includes multiple openings therein, pins extending from the surface portion pass through the openings for limiting ring guard cover movement.

10. The slicer of claim 8 wherein the gap has a thickness of between about 0.100 inches and about 0.175 inches, and the food catching wall a thickness between about 0.030 inches and 0.080 inches.

11. A slicer for use in slicing a food product, the slicer comprising:

a slicer body;

a circular slicer knife mounted for rotation relative to the slicer body, the slicer knife having a peripheral cutting edge;

a carriage mounted for moving food product back and forth past the circular slicer knife;

a ring guard disposed about the peripheral cutting edge along at least a portion of a non-cutting zone of the circular slice knife, a gap between ring guard and the peripheral cutting edge;

a ring guard cover including a food catching wall positioned in the gap for catching food product thrown off the circular slicer knife toward the ring guard, the ring guard cover removable for cleaning,

wherein the ring guard cover includes multiple openings therein, projections extending from the ring guard pass through the openings for limiting ring guard cover movement.

12. The slicer of claim 11 wherein at least one of the openings is a slot-type opening.

13. A slicer for use in slicing a food product, the slicer comprising:

a slicer body;

a circular slicer knife mounted for rotation relative to the slicer body, the slicer knife having a peripheral cutting edge;

a carriage mounted for moving food product back and forth past the circular slicer knife;

a ring guard disposed about the peripheral cutting edge along at least a portion of a non-cutting zone of the circular slice knife, a gap between ring guard and the peripheral cutting edge;

a ring guard cover including a food catching wall positioned in the gap for catching food product thrown off the circular slicer knife toward the ring guard, the ring guard cover removable for cleaning,

wherein the ring guard includes a circumferentially extending surface aligned with the peripheral cutting edge and forming a partial right circular cylinder, the food catching wall extends circumferentially and forms a partial right circular cylinder.

14. A slicer for use in slicing a food product, the slicer comprising:

a slicer body;

a circular slicer knife mounted for rotation relative to the slicer body, the slicer knife having a peripheral cutting edge;

a carriage mounted for moving food product back and forth past the circular slicer knife;

a ring guard disposed about the peripheral cutting edge along at least a portion of a non-cuffing zone of the circular slice knife, a gap between ring guard and the peripheral cutting edge;

a ring guard cover at least partially surrounding the ring guard so that a portion of the ring guard cover is positioned in the gap for catching food product thrown off the circular slicer knife toward the ring guard, the ring guard cover removable for cleaning,

wherein an upper portion of the non-cutting zone has a knife sharpening assembly located therealong, the ring guard cover includes an upper portion positioned in a gap between the knife sharpening assembly and the peripheral cutting edge, and

wherein a movable knife guard member is positioned adjacent the peripheral cutting edge of the knife proximate to the knife sharpening assembly, the upper portion of the ring guard cover positioned between the movable knife guard member and the peripheral cutting edge.

15. The slicer of claim 14 wherein the ring guard includes a circumferentially extending surface aligned with the peripheral cutting edge and forming a partial right circular cylinder.
