  • Patent number: 5245898
    Abstract: A safe lift device for a slicing machine as provided which enables at least a portion of the slicing machine to be raised from the table or counter upon which it rests. Intermediate the two legs to be raised, a retention leg is pivotally attached to the slicing machine. Also connected to the slicing machine and the retention leg is a lever arm assembly. As the lever arm is raised, the retention leg descends toward the table or counter. Continued raising of the lever arm causes the retention leg to exert a downward force on the table, and thus an upward force on the slicing machine. A ratchet and pawl mechanism connected to the retention leg and the lever arm assembly allows the user to lock the lever arm while the slicing machine is in a raised position thus preventing the slicing machine from falling. A safety switch disenables the motor driving the slicing knife as soon as the machine is lifted approximately one inch or more.
