Patent number: 11193726Abstract: Trigger assemblies are provided for restraining a firing pin of a firearm on a selective basis. The triggers assemblies include a first and a second lever mounted for rotation within a housing. The first lever is configured to be rotated by the user, and rotation of the first lever imparts rotation to the second lever to initiate the discharge of the firearm. The trigger assemblies also include a safety mechanism having a safety lever that is movable between a first and a second angular position. The safety lever is configured to prevent movement of the first and second levers when the safety lever is in its first angular position, thereby preventing discharge of the firearm.Type: GrantFiled: May 1, 2020Date of Patent: December 7, 2021Assignee: WHG Properties, LLCInventors: William H. Geissele, David Duhaime

Patent number: 10809030Abstract: Trigger assemblies are provided for initiating the discharge of a firearm. The triggers assemblies include a first and a second lever mounted for rotation within a housing. The first lever is configured to be rotated by the user, and rotation of the first lever imparts rotation to the second lever to initiate the discharge of the firearm. The trigger assemblies have a safety mechanism that includes an interfering member configured to be positioned in proximity to the first and the second levers on a selective basis so that the interfering member simultaneously interferes with movement of both the first and the second levers, and thereby provides multiple points of interference that each prevent discharge of the firearm.Type: GrantFiled: September 25, 2018Date of Patent: October 20, 2020Assignee: WHG Properties, LLCInventors: William H. Geissele, David Duhaime

Methods of manufacturing a segmented brush seal for sealing between stationary and rotary components
Publication number: 20070214628Abstract: A method of forming brush seal segments includes mounting a pair of full form plates having opposite arcuate edges in back-to-back relation and wrapping wire about the form plates in multiple passes to form wire runs at angles, e.g., 35-45° relative to radii of the arcuate edges. Half form plates are assembled to opposite sides of the full form plates adjacent one edge of the subassembly. The wire wrap adjacent the one edge of the full form plates is removed. Welds are applied between each adjacent half and full form plates. The inner edges of the wrapped wire and inner frame members of the full form plates are removed. The assembly is then separated to form a pair of arcuate brush seal segments.Type: ApplicationFiled: March 17, 2006Publication date: September 20, 2007Applicant: General Electric CompanyInventors: William Adis, David DuHaime, Michael Mack
