Patent number: 7784799Abstract: The apparatus and method for sealing at least two surfaces includes a sealing member with an attachment portion fixed to one of the surfaces, and a seal portion connected to the attachment portion. The seal portion of the sealing member includes a deformable segment that may be received and retained by a receiving aperture that is defined by at least one of the surfaces. The receiving aperture may further be defined by at least one engagement member extending from at least one of the surfaces. At least one coating, such as paint, may also be located on a side of the sealing member opposite the surfaces. The seal may be engaged and disengaged without requiring reapplication of the coating. Thus, the present invention provides an effective technique for sealing parts of an object, such as sealing a door, panel, cover or the like to a surrounding structure.Type: GrantFiled: December 31, 2003Date of Patent: August 31, 2010Assignee: The Boeing CompanyInventor: Keith A.

Patent number: 7775770Abstract: A flexible, resilient seal protects a bearing in a pitch joint of a helicopter blade assembly from contaminants. The seal includes a flexible, resilient body having a first end bonded to a stationary portion of the joint, and a second end biased into sealing engagement with a displaceable portion of the joint. The body includes an intermediate bellows section surrounding the bearing that expands and contracts to accommodate displacement between the stationary and movable portions of the joint. The second end of the seal includes a lip that rubs on a sacrificial wear layer formed on the second portion of the joint.Type: GrantFiled: December 21, 2006Date of Patent: August 17, 2010Assignee: The Boeing CompanyInventor: Steven R. Carbaugh

Patent number: 7735836Abstract: A hollow oven gasket has a flexible tubular member with tubular wall and fasteners in the form of clips that are captured within and extend through the wall. First and second free ends of a length of the gasket material are brought together in a termination to form a closed loop gasket member. The first end of the device is at least partially collapsed to form a male end. The second opposing end is left uncollapsed to form a female end. The male end is received within the female end to form a joint held together by engagement of the clips adjoining the joint with an oven face surrounding an oven mouth or an oven door.Type: GrantFiled: September 11, 2006Date of Patent: June 15, 2010Assignee: Davlyn Manufacturing Company, Inc.Inventor: James J. Bono, Jr.
