Patent number: 8794313Abstract: A debris barrier snap fits to a tubular groove of one of the tubulars that define the annular gap in which the barrier is to be mounted. It is loosely mounted so that it can center itself in the annulus as the relatively moving members go out of a concentric arrangement. The continuous carbon fiber material used for the debris barrier has lubricious qualities to act as a bushing when the annulus shape changes due to movement of the tubulars out of a concentric relationship. An outer or inner groove on the barrier acts to trap and retain small particles that manage to advance between the barrier and the outer tubular. The snap fit is accomplished with flexible spaced apart fingers with grip surfaces to engage a groove on one of the tubulars. The barrier has low expansion under thermal loads that acts to stop the entrance of debris.Type: GrantFiled: August 5, 2011Date of Patent: August 5, 2014Assignee: Baker Hughes IncorporatedInventors: Donald T. Heckel, James R. Zachman

Patent number: 6557941Abstract: Three mechanical locks are part of a mechanism for adjusting and dumping a vehicle seat. A master mechanical lock attaches to the seat back. When it is unlocked, depending on the condition of the other locks, one can adjust or dump the seat. A dumping mechanical lock also attaches to the seat back through an intermediary of a slave mechanical lock. When the dumping mechanical lock is unlocked, a connection to the master mechanical lock also opens that lock to allow the seat back to dump. When one unlocks just the master mechanical lock, a connection between that lock and the slave lock unlocks the slave lock. When that lock is unlocked, one can adjust the distance of dumping mechanical lock to the seat back. Because the slave lock remains locked during dumping, the distance between the dumping mechanical lock and the seat back remains constant after dumping. A latch mechanism keeps the dumping lock unlocked until the dumping lock returns to a predetermined position.Type: GrantFiled: January 7, 2000Date of Patent: May 6, 2003Assignee: Porter Engineered Systems, Inc.Inventors: Donald T. Heckel, Jr., Kevin N. Tribbett

Patent number: 6315361Abstract: A system for adjusting and dumping the position of a seat, such as a vehicle passenger or driver's seat, utilizes simultaneously translating master and slave adjustment rods to pivot the seat back frame about a pivot point. Each adjustment rod is locked in a passenger pre-set position by a corresponding locking mechanism. This preset position is “remembered” by way of a marker selectively engaged to the master adjustment rod, and is restored when the marker resides within a marker dock affixed to the locking mechanism. A user adjustment input is operable to release the two locking mechanisms and the marker from the corresponding rods so that the rods can freely translate as the passenger adjusts the angle of inclination of the seat back. When the adjustment input is released, the locking mechanisms and marker re-engage to provide the memory function for the system.Type: GrantFiled: April 24, 2000Date of Patent: November 13, 2001Assignee: Porter Engineered Systems.Inventors: Joseph Mark Stone, Donald T. Heckel, Jr.

Patent number: 6116103Abstract: A threaded leadscrew moves axially within the housing of a linear actuator. The leadscrew's movement rotates a threaded gear nut that surrounds the leadscrew. Stopping the gear nut rotation prevents leadscrew translation. The locking mechanism for selectively blocking rotation of the gear nut includes a cam mounted on the housing, which connects remotely to a user actuated handle. A lever, which mounts on the cam, has a tooth movable between adjacent teeth on the gear nut. The cam also has a blocker that engages the lever. When the cam is in the closed position, the blocker prevents the lever from moving to its released position away from the gear nut's teeth. When the cam is moved to the released position, the blocker releases the lever and allows it to move away from the gear nut. The lever has an opening that is somewhat bigger than a pin on the cam that extends into the opening. When the pin reaches one surface of the opening, it pulls the lever out of its engaged position.Type: GrantFiled: May 29, 1998Date of Patent: September 12, 2000Assignee: P. L.

Patent number: 6003394Abstract: The actuator includes a housing (12) and a gear nut (64) within the housing (12). A leadscrew (78) on which the gear nut (64) is threaded traverses the housing (12). As the leadscrew (78) moves axially, the gear nut (64) rotates. To prevent misalignment between the gear nut (64) and leadscrew (78), the gear nut's outer walls (74 and 76) and bearing surfaces (30 and 46) within the housing (12) permit the gear nut's axis of rotation to pivot in any direction along with any pivoting of the leadscrew (78), while allowing the gear nut (64) to rotate about the leadscrew (78). Therefore, if the leadscrew (78) is not aligned with the housing (12), the leadscrew will pivot the gear nut (64) so that the gear nut (64) remains aligned with the leadscrew (78) and movement of the leadscrew (78) can continue.Type: GrantFiled: July 31, 1998Date of Patent: December 21, 1999Assignee: P.L. Porter Co.Inventor: Donald T. Heckel, Jr.

Patent number: 5689995Abstract: The actuator includes a housing and a gear nut within the housing. A leadscrew on which the gear nut is threaded traverses the housing. As the leadscrew moves axially, the gear nut rotates. The actuator allows a manually controlled ball in a groove to project into castellations on the outside of the gear nut to prevent the nut from rotating. This locks the leadscrew. Disengaging the ball from the gear nut releases the gear nut and leadscrew. To prevent misalignment between the gear nut and leadscrew, the gear nut's outer walls and the housing's inner walls are spherical against each other. A bearing may be in between. This permits the gear nut's axis of rotation to pivot in any direction along with any pivoting of the leadscrew while the gear nut still can rotate about the leadscrew. Therefore, if the leadscrew is not aligned with the housing, the leadscrew will pivot the gear nut so that the gear nut remains aligned with the leadscrew and movement of the leadscrew still occurs.Type: GrantFiled: February 1, 1996Date of Patent: November 25, 1997Assignee: P.
