Abstract
Abstract A sliced food article such as an onion, is quickly diced into a number of rectangular shaped pieces by forcing it through an upper and lower rack of parallel spaced blades such that the upper racks is at right angles to the lower rack forming a rectangular grid. The article, such as an onion, is forced through the rectangular spaces between the two racks of blades by a rectangular array of circular fingers depending from a plunger. The plunger slides along a pair of vertical guides towards and away from the blade. When the plunger is fully engaged with the blades, the free end of the fingers extend completely through the lower rack of blades. The base has four legs to give the device a steady foundation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
233 words
A device for dicing a sliced food article comprising: a base; a slide guide means connected to the base; a removable rectangular shaped blade assembly with four sides, said blade assembly contains slide guide ways in which said slide guide means pass through; said blade assembly rests on said base an upper rack of parallel spaced tensioned blades mounted within said blade assembly and fastened to two opposing sides of said blade assembly; a lower rack of parallel spaced tensioned blades mounted within said blade assembly in a plane parallel with the upper rack of blades and rotated ninety degrees such that said upper rack and said lower rack form a substantially rectangular shaped grid; a plunger having slide guide ways located at the outer perimeter of the plunger in which the slide guides engage, the plunger transversing towards the base and returning along the slide guide means; a rectangular array of fingers depending from the plunger which freely engage within the rectangular spaces between the upper and lower racks of blades when the plunger is moved towards the blades, the fingers each comprising a linear element having two ends, one end of each finger being attached to the plunger and the other end being free, the fingers being long enough to substantially pass through the lower rack of blades when the movement of the plunger into engagement with the base is terminated.
