  • Patent number: 4521147
    Abstract: A double action blind rivet assembly comprising an outer sleeve member with an annular head flange at one end and having an initial outside diameter such that it is receivable through the holes in the workpieces and a length such that it projects from the blind side of the workpieces for the formation of a blind head therein; an inner sleeve member with an annular head flange at one end and having an outside diameter larger than the inside diameter of the outer sleeve member so that, when the inner sleeve member is driven into the outer sleeve member from the accessible side of the workpieces, it will expand the outer sleeve member into a prescribed interference fit by expanding the holes through the workpieces with the inner sleeve member also having a length such that it projects from the blind side of the workpieces after it is driven into the outer sleeve member; and internally supporting the inner sleeve member while it is being driven into the outer sleeve member with a blind head former section thereon

  • Patent number: 4405256
    Abstract: A method of forming a fastener joint in a composite material work piece subject to an operating load comprising the steps of forming a hole of a prescribed hole diameter through the composite material work piece placing a tubular metal sleeve member with a compressible cushion layer around the outside thereof within the hole through the work piece; non-elastically expanding the tubular metal sleeve member radially and circumferentially to force the cushion layer into contact with the hole surface and compress the cushion layer; and placing a fastener in the tubular metal sleeve member to maintain the sleeve member radially and circumferentially expanded and the cushion layer compressed to a thickness to transmit the operating load from the work piece to the fastener through the cushion layer and sleeve member. The joint formed by the method is also disclosed.

  • Patent number: 4164807
    Abstract: A method of coldworking a hole through a work piece which includes placing a seamless tubular member within the hole with a prescribed hoop strength to allow the tubular member to be expanded and prescribed column strength which prevents axial movement of the outside of the tubular member as the tubular member is expanded, holding the tubular member within the hole so that the tubular member is substantially axially fixed with respect to the hole, and passing an expansion mandrel through the inside of the seamless tubular member to radially and circumferentially expand the tubular member sufficiently to induce a compressive stress gradient of a prescribed magnitude in the material of the work piece substantially uniformly about the entire inside surface of the hole so as to increase the fatigue strength thereof.

  • Patent number: 4102030
    Abstract: A sleeve member for positioning between the fastener and work pieces within aligned holes through the work pieces. The sleeve member has a tubular side wall with outwardly directed bends formed therein which are partially flattened out during the assembly of the fastener in the work pieces so that the natural resiliency of the sleeve member compensates for discrepancies in the holes and fastener and which may be coated with a sealant prior to assembly so that the bends act as reservoirs for the sealant to insure sealing of the fastener joint.
