## Abstract

A food cutting machine for cutting food into strips or cubes has first and second rotatable shafts, each having an array of cutter discs thereon. The cutter discs on one shaft are offset from corresponding discs on the other shaft and form cutter pairs therewith, the spacing between pairs being substantially greater than the spacing between the discs forming the pairs. Guide means extending between cutter pairs define the maximum thickness of meat that can be cut, and the discs forming a pair overlap a distance equal to or greater than one-half the spacing between the guide means.

## Claims

### Claim 1

A food slicing machine comprising, a first frame member having side walls and a second frame member having side walls adapted to be superposed on said first frame member, said second frame member having a top surface and an aperture therein;
said first and second frame members together defining a plurality of apertures in the side walls thereof;
first and second parallel shafts mounted in said apertures and extending between opposed side walls;
an array of a plurality of first spaced cutting discs mounted on said first shaft;
first means for maintaining said first discs in a first spaced relationship;
a second array of a plurality of second spaced cutting discs mounted on said second shaft;
second means for maintaining said second discs in a second spaced relationship;
said first and second arrays defining a cutting region;
each of said second discs on said second shaft being offset from a corresponding first disc on said first shaft a distance of from the thickness of a disc to twice the thickness of a disc and forming a disc pair with said corresponding first disc for forming a single cut by said pair in the food being sliced, each of said disc pairs thus formed being spaced from adjacent disc pairs a distance substantially greater than the distance between the discs forming a pair and substantially equal to the desired thickness of the slices to be cut in the food;
first and second food guide means extending substantially normal to the axes of said first and second shafts and extending into the spaced between disc pairs, said first guide means being spaced from said second guide means a distance defining the maximum allowable thickness of food to be cut;
the diameter of each of the discs in a disc pair and the spacing of said first and second shafts being such that the discs in each disc pair overlap a distance equal to or greater than one-half the spacing between said first and second guide means;
means for altering the spacing between said first and second guide means; and
means for rotating said first and second shafts to cut the food.

### Claim 2 (depends on 1)

A food slicing machine as claimed in claim 1 wherein said means for rotating comprises means for rotating said first shaft in counter relationship to the rotation of said second shaft.

### Claim 3 (depends on 1)

A food slicing machine as claimed in claim 1 wherein said means for rotating comprises means for rotating said first shaft at a different speed of rotation than said second shaft.

### Claim 4 (depends on 1)

A food slicing machine as claimed in claim 1 and further comprising bushing means through which said first and second shafts extend mounted in each of said plurality of apertures.

### Claim 5 (depends on 1)

A food slicing machine as claimed in claim 1 wherein each of said first and second guide means is mounted on said top surface and comprises a plurality of fingers extending through said cutting region, each pair of adjacent fingers straddling a cutter pair.

### Claim 6

A food slicing machine for slicing food into strips comprising a frame;
first and second spaced parallel shafts mounted in said frame;
means for rotating said first and second shafts;
an array of spaced cutter blades mounted on said first shaft;
an array of spaced cutter blades mounted on said second shaft forming a cutting region with the blades on said first shaft, each cutter blade on said first shaft being closely adjacent to a corresponding cutter blade on said second shaft to form an overlapped cutter pair for making a single cut in the food;
adjacent cutter pairs being spaced from each other a distance substantially greater than the distance between the discs forming a cutter pair and equal to the desired thickness of the food strip to be produced;
first and second spaced guide means extending from above said frame to the cutting region and between adjacent cutter pairs for defining the maximum allowable thickness of food to be cut;
the cutter blades forming each overlapped cutter pair being overlapped a distance equal to or greater than one half other spacing between said first and second guide means within the cutting region.

### Claim 7 (depends on 6)

A food slicing machine as claimed in claim 6 wherein said means for rotating said first and second shafts comprises a gear member mounted on each shaft adapted to mesh with the gear mounted on the other shaft, and a handle for rotating one of said shafts.

### Claim 8 (depends on 7)

A food slicing machine as claimed in claim 7 wherein one of said gear members is of larger diameter than the other gear member.

### Claim 9 (depends on 6)

A food slicing machine as claimed in claim 6 wherein said arrays of cutter blades define a cutting region interiorly of said frame, and interior means on said frame for separating said cutting region from said means for rotating said shafts.

### Claim 10 (depends on 6)

A food slicing machine as claimed in claim 6 wherein said first and second guide means each comprises a plurality of fingers.

### Claim 11 (depends on 10)

A food slicing machine as claimed in claim 10 wherein adjacent fingers straddle a cutter blade.

### Claim 12 (depends on 10)

A food slicing machine as claimed in claim 10 wherein each of said fingers substantially fills the space between adjacent cutter blades mounted on the same shaft.

### Claim 13 (depends on 6)

A food slicing machine as claimed in claim 6 wherein the spacing between adjacent cutter blades forming a cutter pair is from a cutter blade thickness to twice a cutter blade thickness.
