Claims18
An insert, comprising, in combination:
- a sleeve,
- an exterior thread formed on said sleeve,
- an interior thread formed in said sleeve,
- a shoulder on one end of said sleeve,
- a bore in said shoulder axially aligned with said exterior thread, and
- a pin passing through said bore;
- wherein said exterior thread has an upper surface angle less than or equal to a lower surface angle.
A device for providing a lining in an object, comprising, in combination:
- a sleeve having an exterior diameter substantially complemental to a bore in the object to be lined,
- a peripheral shoulder emanating from one end of said sleeve,
- a pin dimensioned to lodge in said shoulder and along an interface between said sleeve and the bore including an exterior thread on said device wherein said exterior thread has an upper surface angle less than or equal to a lower surface angle.
A sleeve having an interior thread and an exterior thread, said exterior thread includes a vertically aligned clearance to receive a pin therewithin wherein said exterior thread has an upper surface angle less than or equal to a lower surface angle.
A sleeve having an interior thread and an exterior thread, said exterior thread includes a vertically aligned clearance to receive a pin therewithin including a shoulder emanating from one end of said sleeve, said shoulder having a cusp on a bottom surface thereof.
An insert, comprising, in combination:
- a sleeve having interior and exterior threads,
- a shoulder on one end of said sleeve having a hole passing therethrough,
- clearance in said exterior threads aligned with said hole, and
- a pin dimensioned to pass through said hole and reside within said clearance;
- including sealing means on said insert to provide an impervious barrier.
An insert, comprising, in combination:
- a sleeve having interior and exterior threads,
- a shoulder on one end of said sleeve having a hole passing therethrough,
- clearance in said exterior threads aligned with said hole, and
- a pin dimensioned to pass through said hole and reside within said clearance,
- wherein said shoulder includes means for causing metal deformation upon installation.
A method for repairing or fabricating a receiving area for an object, the steps including:
- providing a thread within a bore to receive an insert,
- forming said insert with a shoulder having a cusp on a surface adjacent a length of said insert;
- threading said insert into said threaded bore,
- fixing said insert into said bore by inserting a pin into the bore's and insert's threads to preclude further rotation of said insert,
- and installing the object in said insert.
