  • Safety device latch for a paper cutter
    Patent number: 5320011
    Abstract: A safety latch device for a paper cutter movably attached to the cutting arm of the paper cutter. The safety latch has a base catch, an arm catch and a trigger. The base catch engages with an extended portion of the base of the paper cutter to prevent a user from raising the cutting arm. The arm catch engages with a top surface of the cutting arm to prevent the safety latch from interfering with the cutting arm during operation. The trigger allows the user to disengage the base catch from the extended portion of the base so the cutting arm can be lifted.
