Abstract
A horizontal disc-like tool head is detachably mounted on an upper coupling portion of an elongated hub, while a lower coupling portion of the hub is adapted to be coupled to and rotated by the tool drive shaft of a food processor. The tool head has a socket underneath it adapted to receive the upper coupling portion of the hub, which is inserted into this socket by motion in a horizontal, i.e. radial, direction parallel to the plane of the tool head, being held in the socket by a pair of detents. The elongated hollow hub includes a spring-loaded push rod or bolt lock in its bore which can be elevated into locking position between the detents and inserted into the socket to prevent the release of the socket from the hub during operation. This push rod includes a manual release button for withdrawing the push rod from the socket, thereby returning the detents to their original unlocked condition. By providing a variety of disc-like tool heads having different cutting structures for performing different food processing functions, a variety of operations may be performed conveniently by changing the tool heads, without requiring a separate hub for each rotary tool. Convenience is provided to the user, for the flat disc-like tool heads can be easily and compactly stored.
