    摘要： A reciprocating sensing shield for use in connection with a power press such as a press break or bending machine is operatively mounted on the press ram for relative vertical movement and is controlled to be positioned to guard the "pinch point" of the dies and furthermore to stop downward movement of the ram should an operator's fingers or hands be in the proximity to the "pinch point" just prior to the movable die arriving thereat. The ram and shield descend as a unit until the ram reaches the "pinch point" at which time the shield is positioned to cover the break thereby to prevent an operator from inserting his hands or fingers into the break. As the ram reaches the "pinch point", the sensing shield immediately raises clear of the break. As the work piece is formed by continued descent of the ram, the ram reverses (rises) and the sensing shield is carried upwardly with it. When the ram is top dead center, the sensing shield is caused to drop into its lowermost position relative to the ram and the system is in readiness for another cycle. Should an operator's hand be in the danger area beneath the sensing shield as the ram and shield are lowering, engagement with the operator's hand triggers a mechanism which stops the ram. Thus, both shielding and sensing functions are provided.

    摘要： A clutch or coupling device for interconnecting a drive shaft to an axially aligned driven shaft which supports drive sprockets for chain belt conveyor of a press characterized by a disk member connected to the drive shaft for rotation therewith and having a plurality of recesses which have converging planar side walls and are circumferentially spaced on a circle coaxial with the axis of the drive shaft to receive circumferentially spaced dogs which have slanting plane surfaces extending substantially parallel to the side walls of the grooves and are mounted on a flange member which is connected by a mounting device to the driven shaft. The mounting device directly transfers rotational motion between the flange member to the driven shaft but enables relative axial movement of the flange member from a first position with the slanting plane surfaces of the dogs engaged with the side walls of the recesses to transfer torque between the shaft to a second position with the slanting plane surfaces withdrawn from engagement and includes a spring device for biasing the flange member to the first position. In operation, when an overload occurs, the increased torque acting on the engaged slanting surfaces of the dogs and recesses overcomes the force of the spring device and urges the flange member axially to the second position to disengage the coupling between the drive shaft and driven shaft.
