摘要： A three position cylinder assembly having an outer cylinder connected between two bases defining a cap end and a head end. A stationary tubular member is secured to the cap end of the outer cylinder at a port to provide fluid access into the outer cylinder. A first and second piston are disposed within the outer cylinder and have reciprocal movement therein. Each piston is connected to a rod which is concentric with the tubular member. The head end has an aperture for receiving the rods for extension beyond the outer cylinder. The tubular member has a stop at an end and the first piston and rod have reciprocal movement along the tubular member, wherein the stop defines a stable mid-position of the cylinder assembly. The second piston and rod have reciprocal movement along the first rod between the first piston and head end, wherein the head end defines a stable fully extended position of the cylinder assembly.

摘要： The subject invention provides a locating assembly for centering and securing a work piece. The locating assembly includes a body. The body defines an internal cavity and an opening from the cavity to the exterior of the body. A locating pin is disposed in the cavity and extends along an axis out of the opening. An actuator moves the locating pin rectilinearly along the axis. A pair of fingers are supported by the locating pin and move radially into and out of the locating pin, transversely to the axis. A central post rotates in response to the rectilinear movement of the locating pin. A dowel extends from an end of the central post into a slot in the finger. The central post moves the dowel in an arcuate path through the slot to radially move the finger simultaneous with the rectilinear movement of the locating pin.

摘要： A closed circuit synchronizing cylinder assembly for synchronously moving at least two external devices such that the devices move at the same rate and maintain essentially the same level within a small deviation. The synchronizing cylinder assembly has a cylinder with a movable piston and rod for each external device. The piston divides the interior of the cylinder into a rod outer diameter chamber, a rod inner diameter chamber and a third chamber. The rod outer diameter chamber and rod inner diameter chamber have equal areas and hydraulic fluid therein and third member is open to atmosphere. The hydraulic fluid in the rod outer diameter chamber of one cylinder communicates with the rod inner diameter chamber of another cylinder driving the reciprocal movement of the piston and rod. An equalizing vent located in each cylinder communicates between the rod outer diameter chamber and the rod inner diameter chamber to allow passage of hydraulic fluid between chambers to allow the cylinders to fully stroke and re-synchronize each cycle automatically.
