  • Patent number: 5615591
    Abstract: A food product slicing machine includes a coupling and associated interlock mechanism for connecting and disconnecting a carriage arm of the food slicing machine to and from a reciprocating carriage base mounted to the housing of the machine. The coupling includes a cylindrical mounting head which is rotatably mounted in the carriage base by a bracket. The mounting head contains a slot for slidably receiving a foot of the carriage arm, and the bracket also contains a slot with which the mounting head slot can be aligned through rotation of the mounting head within the bracket. The mounting head slot and bracket slot must be aligned in order to attach or remove the carriage arm's foot to or from the carriage base. The interlock mechanism is provided to prohibit the alignment of the slots when the gauge plate of the slicing machine is not in a safe position. Accordingly, the carriage arm may not be removed from the carriage base when the gauge plate is not in the safe position.
