Abstract

A food slicer to slice food items in variable widths or thicknesses, the slicer has a frame with an upper and lower platform guide plate to slice food. It also has a translational guide system which moves the top guide plate within a parallel plane between the longitudinally aligned side rails. The translational guide system takes on many forms. One form is a rack and pinion system where the rack is attached to the top guide plate and the pinion is attached to one of two transversely aligned axles. The axles allow for range of movement of the guide plate between an upper location and a lower location. By adjusting the translational guide system, the top guide plate can move up and down between the upper and lower limits or locations which creates differing widths of the cutting slot. The top guide plate has a removable julienne blade plate portion. The bottom guide plate has a removable horizontal blade portion. Moving the food up and down the guide plates passes the food items over the julienne blades and the horizontal blade and cuts the food item which drops through the cutting slot.
