Abstract
A gripper assembly for clamping articles comprises a first clamp member and a second clamp member pivotal relative to the first clamp member. An actuator pivots the second clamp member relative to the first clamp member from an open position into a closed position. A coil spring is compressed when the second clamp member is in the open position. A pin engaging in a slot maintains the coil spring in the compressed condition when the second clamp member is in the open position. A releasable locking device holds the second clamp member in a closed position. The locking device includes a latch that can be mounted in one of two positions on the first clamp member. The latch is biased into engagement with one of two latch blocks, depending on the position of the latch, to hold the second clamp member in the closed position.
