Abstract
A fluid actuated tool for pressing work pieces with a controlled force and dwell time is provided. The tool includes a fixed jaw and a movable jaw which is movable toward and away from the fixed jaw which arrangement allows a work piece to be squeezed between the jaws. A fluid actuated cylinder is provided which is connected to the movable jaw. The connection includes a coil spring and link and slot arrangement wherein force is transmitted to the work piece between the jaws by compression of the coil spring independent of the fluid force, and the link and slot arrangement allows limited movement of the piston independent of the movable jaw when the jaw meets the resistance of the work piece. The spring thus allows for a dwell time as well as a force independent of the fluid pressure.
