## Abstract

A cutting accessory for a food processor has a body that fits within the food processor's bowl and lid. The body supports a cutting disc that is offset to the food processor's spindle. The cutting disc is driven by the rotation of the spindle.

## Claims

### Claim 1

A food processor, comprising:
a lid;
a bowl;
a spindle rotatably arranged with the bowl; and
an accessory device, the accessory device comprising:
a body having an exterior shaped to cooperate with an interior surface of the bowl such that the body is immobilized against rotation relative to the bowl and the lid;
the body having a first opening that receives an end of the spindle and a second through opening for locating a cutting disc, wherein the cutting disc is a spiral cutting disc;
when the cutting disc is aligned with the second through opening, the cutting disc is offset from a rotational center of the spindle; and
rotation of the spindle causes rotation of the cutting disc relative to the body, such that a food is processable by the food processor to a spiral cut food.

### Claim 2 (depends on 1)

The food processor of claim 1, wherein: the bowl has an internal rim and the accessory device rests on the rim.

### Claim 3 (depends on 1)

The food processor of claim 1, wherein: the accessory device fits within the bowl when the lid is on.

### Claim 4 (depends on 1)

The food processor of claim 1, wherein: the first opening is a through opening.

### Claim 5 (depends on 1)

The food processor of claim 1, wherein:
the spindle passes through the first opening so that a tip of the spindle is stabilized by a bush accessible from an underside of the lid.

### Claim 6 (depends on 5)

The food processor of claim 5, wherein: the bush is supported by a resilient polymer.

### Claim 7 (depends on 5)

The food processor of claim 5, wherein: the lid has a feed tube with an insert that aligns with the second opening and that cooperates with a safety cut-out mechanism.

### Claim 8 (depends on 7)

The food processor of claim 7, wherein: the safety cut-out mechanism passes through a handle of the bowl.

### Claim 9 (depends on 1)

The food processor of claim 1, wherein: a locating key extends between the body and the bowl.

### Claim 10 (depends on 1)

The food processor of claim 1, wherein: a rotational speed of the cutting disc is less than a rotational speed of the spindle.

### Claim 11 (depends on 1)

The food processor of claim 1, further comprising an output gear supported for rotation by the second through opening in the body, whereby rotation of the spindle results in rotation of the output gear.

### Claim 12 (depends on 11)

The food processor of claim 11, wherein: the output gear has a second bore in which the cutting disc is removably received, the second bore aligning with the second opening.

### Claim 13 (depends on 1)

The food processor of claim 1, wherein:
the body supports a drive gear that cooperates with the first opening for engaging the end of the spindle, whereby rotation of the drive gear causes rotation of the cutting disc.

### Claim 14 (depends on 13)

The food processor of claim 13, wherein: the drive gear is part of a planetary gear train.

### Claim 15 (depends on 14)

The food processor of claim 14, wherein:
the body is sealed such that the cutting disc is isolated from the planetary gear train.

### Claim 16 (depends on 14)

The food processor of claim 14, wherein: the planetary gear train has one or more fixed planet gears.
