ABSTRACT:
The invention is related to a safety device for a press machine or the like. The safety device includes a first guard plate which slidably extends over the machine access area and is powered by an air cylinder having a movable rod connected to a movable arm of the first guard plate. The device also has a second guard plate slidably attached to the first guard plate which has a switch means for deactivating the air cylinder and therefore stopping the forward motion of the first guard plate whenever the second guard plate exhibits movement toward said first guard plate. For example, when a user's hand is in the access area and the second guard plate strikes the hand thereby slidably moving the second guard plate toward the first, the safety device is deactivated and the guard plates move away from the machine access area.
