Patent number: 8561974Abstract: A pin clamp assembly having a housing, locating pin, at least one finger, a drive rod and an actuator is provided. At least a portion of the locating pin may be extendable exterior of the housing. The finger is located adjacent the locating pin and movable relative thereto. The drive rod is movable and is engagable with the finger to move the finger between clamped and unclamped positions. The actuator drives the locating pin and the drive rod. Movement of the locating pin and drive rod is linear only and no rotational movement of the locating pin and drive rod is employed to move the finger between clamped and unclamped positions.Type: GrantFiled: November 10, 2008Date of Patent: October 22, 2013Assignee: PHD, Inc.Inventors: Kenneth A. Steele, Bruce D. McIntosh, Steven M. Moilanen, William E. Davenport, William D. Givens, Parag Patwardhan

Patent number: 8366085Abstract: A locating pin assembly is provided. The assembly includes a body and a cylinder assembly for moving a ram in a reciprocally linear manner. A bearing is coupled to the ram and configured to engage a bearing wedge to reduce “play” between the ram and the assembly. Illustratively, the bearing and bearing wedge reduce or substantially eliminate this “play” to prevent axial rotation of the ram.Type: GrantFiled: June 19, 2008Date of Patent: February 5, 2013Assignee: PHD, Inc.Inventors: Clinton L. Alexander, Parag Patwardhan, Bruce D. McIntosh

Patent number: 8136803Abstract: An armover clamp assembly is provided that includes a housing, an actuator, a cam, a first link, a pivot pin, a driver, a rotating pin, and an arm. The cam includes a cam slot disposed therethrough and is attached to the actuator for linear movement inside the housing. The cam slot has a cam path that includes a locking portion and an extended travel portion. The first link is movably coupled to the cam slot via a cam pin coupled to the link. The cam pin is disposed in and configured to follow the cam path. The pivot pin is coupled to the first link at a position spaced apart from where the cam pin is coupled to the link. The driver is pivotally attached to the pivot pin. The rotating pin extends exterior of the housing and is attached to the driver inside the housing at a location spaced apart from the pivot pin.Type: GrantFiled: January 14, 2008Date of Patent: March 20, 2012Assignee: PHD, Inc.Inventors: Bruce D. McIntosh, Clinton L. Alexander, Parag Patwardhan

Patent number: 7815176Abstract: A pin clamp assembly is provided. The assembly includes a housing, a locating pin, a body, and first and second locks. The locating pin extends from the housing. The body extends from the locating pin. At least a portion of the body is located interior of the housing. The body and locating pin are movable with respect to the housing. The first lock is located on the body and the second lock is configured to selectively couple with the first lock. Selective coupling of the locks prevent the body from moving.Type: GrantFiled: September 27, 2006Date of Patent: October 19, 2010Assignee: PHD, Inc.Inventors: Bruce D. McIntosh, Parag Patwardhan, Kenneth A. Steele

Publication number: 20070267795Abstract: A pin clamp transfer assembly may provide first and second pin clamps. The first pin clamp has a pin that extends from a body with a first end located distal from the body. The second pin clamp also has a pin that extends from a body with a second end located distal from the body. The first end of the first pin is engagable with the second end of the second pin to align the first and second pins. A pin clamp transfer assembly may alternatively have a pin clamp assembly that includes a transfer assist to move a workpiece relative to the pin clamp's pin.Type: ApplicationFiled: January 31, 2007Publication date: November 22, 2007Inventors: Parag Patwardhan, Bruce McIntosh
