Abstract
Abstract Following are disclosed methods and apparatus for facilitating the alignment of the eccentric bores of ''''work side'''' and ''''blind side'''' bushings used in the misaligned, fastener receiving holes of structural members. A shaft is sized to extend into the eccentric bores, and a latch element is laterally carried by the shaft and adapted to extend into, and retract from at least one indentation in the bore of a selected bushing for rotational orientation thereof. An adjustment bushing is carried by the shaft and has a uniform cylindrical wall thickness equal to the minimum wall thickness of the work side bushing. An alignment collar is also carried by the shaft and has an aperture that receives the shaft, the collar having a larger diameter than the diameter of an engaged bushing to enable application of torque and visual reference for detecting axial angularity misalignment between said bushing and its receiving hole in the structural member. When used with the alignment collar, the adjustment bushing gauges and establishes the position of the blind side bushing to enable insertion of the work side bushing and a fastener in a more efficient manner without need for additional rotation of either the blind side or the work side bushing. Hence, the work side and blind side bushings may be accurately aligned through the utilization of both the alignment collar and the adjustment bushing.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
266 words
A method of assembling work side and blind side structural members having generally misaligned, fastener receiving holes through utilization of work side and blind side bushings, said method comprising the steps of: forming eccentric, axially extending bores and exterior lateral surfaces in two bushings; forming an indentation in a selected one of the bores, and an exterior surface of at least one of said bushings; inserting a bushing in the hole of the blind side structural member to define the blind side bushing; inserting an alignment collar onto a shaft; inserting a cylindrical, adjustment bushing onto said shaft, the adjustment bushing having a uniform wall thickness that is equal to the minimum thickness defined by the eccentric bore of the work side bushing and its exterior surface; inserting the shaft through the work side structural member into the bore of the blind side bushing; positioning a latch element carried by the shaft within the said indentation; positioning the alignment collar in contact with the work side structural member; rotating the blind side bushing with the shaft until the exterior wall of the adjustment bushing engages the hole in the work side structural member; inspecting the alignment collar for contact with the work side structural member; retracting the shaft and the adjustment bushing from the vicinity of the structural members; inserting a work side bushing into the receiving hole of the work side structural member with its eccentric bore axially aligned with the eccentric bore of the blind side bushing; securing a fastener in the eccentric but aligned bores of the work side and blind side bushings.
Claim 2
Independent Claim
266 words
A method of assembling work side and blind side structural members having generally misaligned, fastener receiving holes through utilization of work side and blind side bushings, said method comprising the steps of: forming eccentric, axially extending bores and exterior lateral surfaces in two bushings; forming an indentation in a selected one of the bores, and an exterior surface of at least one of said bushings; inserting a bushing in the hole of the blind side structural member to define the blind side bushing; inserting an alignment collar onto a shaft; inserting a cylindrical, adjustment bushing onto said shaft, the adjustment bushing having a uniform wall thickness that is equal to the minimum thickness defined by the eccentric bore of the work side bushing and its exterior surface; inserting the shaft through the work side structural member into the bore of the blind side bushing; positioning a latch element carried by the shaft within the said indentation; positioning the alignment collar in contact with the work side structural member; rotating the blind side bushing with the shaft until the exterior wall of the adjustment bushing engages the hole in the work side structural member; inspecting the alignment collar for contact with the work side structural member; retracting the shaft and the adjustment bushing from the vicinity of the structural members; inserting a work side bushing into the receiving hole of the work side structural member with its eccentric bore axially aligned with the eccentric bore of the blind side bushing; securing a fastener in the eccentric but aligned bores of the work side and blind side bushings.
Claim 3
Dependent Claim
33 words
The method defined by claim 1 in which the work side bushing is manipulated by the engaged alignment collar after the bushing is inserted into the hole of the work side structural member.
Claim 4
Independent Claim
264 words
A method of assembling work side and blind side structural members having generally misaligned, fastener receiving holes through utilization of work side and blind side bushings having eccentric, axially extending bores, said method comprising the steps of: inserting a bushing in the hole of the blind side structural member to define the blind side bushing; inserting an alignment collar onto said shaft; inserting a cylindrical, adjustment bushing onto a shaft that also extends into the bore of the blind side bushing, the adjustment bushing having a uniform wall thickness that is equal to the minimum thickness defined by the eccentric bore of the work side bushing and its exterior surface; positioning a latch element carried by the shaft in engagement with the blind side bushing; positioning the alignment collar in contact with the work side structuraL member; rotating the blind side bushing with the shaft until the exterior wall of the adjustment bushing engages the hole in the work side structural member; inspecting the alignment collar for contact with the work side structural member; retracting the shaft and the adjustment bushing from the vicinity of the structural members; replacing the adjustment bushing on the shaft with a work side bushing; inserting a work side bushing into the receiving hole of the work side structural member by replacing the shaft through the work side structural member into the bore of the blind side bushing; engaging the work side bushing with the adjustment collar and manipulating the work side bushing into the hole of the work side structural member; securing a fastener in the aligned bores.
Claim 5
Independent Claim
