Abstract
A method of supporting an elongated member in a bowl without marking the surface of the elongated member by providing a pair of intermediate surfaces between the tapered surface of the bowl and the contact surface with the elongated member which are approximately perpendicular to each other in order to amplify the force against the pipe in comparison to the force from the bowl.
Claims20
A support assembly for supporting an elongated member within a bowl comprising:
- one or more inclined surfaces within said bowl,
- one or more slip carriers engaging said one or more inclined surfaces,
- two or more slip segments engaging one of said slip carriers on first and second surfaces, said first and said second surfaces being proximately perpendicular to each other,
- such that the force between said slip carrier and said bowl is amplified by the angles between said first surface and said second surface to provide a higher force against said elongated member than said slip carrier provides against said bowl.
A support assembly for supporting an elongated member comprising
- a bowl member with one or more bowl sloping surfaces which slope from a distance further from said elongated member to closer to said elongated member in the direction against which support is provided,
- a slip member with
- one or more slip back surfaces to contact said tapered surfaces,
- two or more slip front surfaces to contact said elongated member,
- said two or more slip front surfaces having an angle between themselves such that the sum of the contact load between said slip front surfaces and said elongated member on one or more of said slip members exceeds the load between said slip back surface and said bowl tapered surface.
A friction support assembly which provides for the assurance of support of an elongated member within a sloping bowl by providing a higher force against said supported member than the force against the supporting bowl, comprising
- a slip carrier to engage said bowl,
- two slip segments to engage said elongated member,
- said two slip segments engaging said slip carrier on intermediate surfaces which are at and angle of approximately ninety degrees relative to each other.
