Abstract
ABSTRACT
A portable food processor comprising a basic unit made up of a base containing an electric motor having a handle portion by which the apparatus may be lifted and an upper portion which includes a feed tube through which foodstuffs can be fed the base and the upper portion being constructed so that the upper portion can be assembled to the base in two different configurations in one of which the basic unit receives a food processing unit consisting of a container having a food processing blade rotatable therein to be driven by the electric motor and in the other of which the basic unit receives a slicing or shredding unit which includes a substantially horizontally arranged disk and an outlet though which sliced or shredded material is delivered. Preferably, a control for the electric motor is provided including a manually operable switch and a set of contacts arranged so that in both configurations of the apparatus the switch cannot be closed manually and unless the upper portion is properly engaged with the base and with either the slicing or shredding unit or the food processing unit.

Claims (3)
1. A portable food processor characterised in that it comprises a basic unit consisting of a base constructed and arranged to stand on a work surface, an electric motor contained within the base arranged to drive either a slicing or shredding unit or a food processing unit and an upwardly projecting handle portion by which the apparatus may be lifted attached to the base, there being associated with the base and removable therefrom an upper portion including a feed tube through which foodstuffs can be fed vertically, the base and the upper portion being constructed so that the upper portion can be assembled to the base in two different configurations in one of which the basic unit receives a food processing unit consisting of a container having a food processing blade rotatable therein to be driven by said electric motor and in the other of which the basic unit receives a slicing or shredding unit including a substantially horizontally arranged disc arranged to be driven through said electric motor, the disc being associated with means defining a space connected to an outlet member constructed and arranged to deliver material sliced or shredded by the disc in a downward direction to a receptacle, the slicing or shredding unit and the food processor unit being of different heights.
2. A portable food processor as claimed in claim 1 wherein means are provided for controlling the operation of the electric motor including a manually operable switch and a set of contacts, means on said upper portion coacting with said switch whereby in both said configurations the contacts cannot be closed manually unless the upper portion is properly engaged with the base and with either the slicing or shredding unit or the food processing unit.
3. A portable food processor as claimed in claim 2 wherein the manually operable switch and the set of contacts are contained within the handle portion, a switch button being provided on the handle portion for manual operation.
