  • Patent number: 6386786
    Abstract: A clamp that is particularly suitable for automated manufacturing or assembly environments, such as on a transfer press, includes a first and a second clamp which engage each other via a joint. The joint is adapted to allow the first and second clamps to both pivot and rotate with respect to each other. A third clamp fits over the joint and selectively secures the first and second clamps in a desired orientation when the third clamp is tightened. The joint may be a ball and socket joint.

  • Patent number: 6182491
    Abstract: A tool mount for mounting tool assemblies on a transfer press, or other type of automated assembly line, includes a bayonet which can be selectively inserted into a receiver mounted on the transfer press rail. The receiver includes a generally tapered channel which receives a tapered portion of the bayonet. The receiver and the bayonet thereby form a dove tail type of junction. The direction of taper is oriented such that the bayonet must be inserted from the back end of the receiver and pushed forwardly to secure it therein. A lock selectively secures the bayonet within the receiver. The lock includes a latch that engages a first cam surface to push the bayonet inwardly into the receiver and thereby prevent it from being removed, while simultaneously insuring a tight fit between the receiver and the bayonet. The lock latch further engages a second cam surface of the bayonet when the bayonet is to be removed from the receiver.
