Patent ID: 6874834

Claim:
A linear slide gripper assembly comprising: a linear slide assembly comprising: a slide having first and second receiving ports both in fluid communication with a fluid source to move the slide between extended and retracted positions; a valve assembly comprising a check valve located within a cavity; wherein both the first and second receiving ports are in communication with the check valve, and each direct a portion of the fluid through the valve and into the cavity; a switch having a chamber that is in fluid communication with the cavity; wherein upon activation of the switch the chamber becomes in selective communication with first and second conduits; a trip coupled to and movable with the slide; wherein movement of the slide causes the trip to activate the switch to release fluid from the switch; and a gripper assembly comprising: an actuator in fluid communication with the first and second conduits to receive the fluid released from the switch to power the actuator; and at least one gripper arm coupled to the gripper assembly; wherein the actuator is engagable with at least one of the arms and moves the arm when the actuator is powered by the fluid from the switch.
