Abstract
Abstract Following is disclosed a method and apparatus for improving the alignment of ''''work'''' and ''''blind side'''' bushings with eccentric bores through utilization of a shaft sized to extend into the bores. A latch element is laterally carried by the shaft and adapted to extend into and retract from indentations in the bores for orienting the bushings. An alignment collar is also carried by the shaft and has an aperture that receives the shaft, with the collar having a larger diameter than the diameter of an engaged bushing to enable application of torque and to give a visual reference for axial angularity misalignment between said bushing and its receiving hole in the structural member. The alignment collar makes more exacting alignment of the bushings possible, particularly when an initial limited interference fit between the bushing and its receiving hole (before final seating) is utilized in the installation procedure.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 words
In a fastener and assembly means including a work side bushing, a blind side bushing, each having eccentric, axially extending bores to receive a shaft and a latch element that extends into an indentation in one of said bushings, all of which cooperate to connect structural members having misaligned fastener receiving holes, the improvement comprising: an alignment collar having aN aperture that receives aid shaft, said collar having a large diameter shoulder that faces and engages the work side bushing; said work side bushing having a planar, exposed surface perpendicular with its axially extending bore; said alignment collar having a planar surface perpendicular with the axis of its aperture and larger than said planar surface of the work side bushing; both said planar surfaces selectively engaging for application of axial force and torque from the collar to the work side bushing whereby the work side bushing may be adjusted with limited interference fit and the collar visually inspected for space between the periphery of the collar and the associated structural member.
Claim 2
Dependent Claim
171 words
In a fastener and assembly means including a work side bushing, a blind side bushing, each having eccentric, axially extending bores to receive a shaft and a latch element that extends into an indentation in one of said bushings, all of which cooperate to connect structural members having misaligned fastener receiving holes, the improvement comprising: an alignment collar having aN aperture that receives aid shaft, said collar having a large diameter shoulder that faces and engages the work side bushing; said work side bushing having a planar, exposed surface perpendicular with its axially extending bore; said alignment collar having a planar surface perpendicular with the axis of its aperture and larger than said planar surface of the work side bushing; both said planar surfaces selectively engaging for application of axial force and torque from the collar to the work side bushing whereby the work side bushing may be adjusted with limited interference fit and the collar visually inspected for space between the periphery of the collar and the associated structural member.
Claim 3
Dependent Claim
182 words
In a fastener and assembly means including a work side bushing, a blind side bushing, each having eccentric, axially extending bores to receive a shaft and a latch element that extends into an indentation in one of said bushings, all of which cooperate to connect structural members having misaligned fastener receiving holes, the improvement comprising: an alignment collar having an aperture that receives said shaft, said collar having a large diameter shoulder that faces and engages the work side bushing; said work side bushing having a peripheral edge perpendicular with its axially extending bore said alignment collar having a planar surface perpendicular with the axis of its aperture and larger than the peripheral edge of the work side bushing; both the peripheral edge of the work side bushing and the shoulder of the alignment collar selectively engaging for application of axial force and torque from the collar to the work side bushing, whereby the work side bushing may be adjusted with limited interference fit and the collar visually inspected for space between the periphery of the collar and the associated structural member.
Claim 4
Dependent Claim
182 words
In a fastener and assembly means including a work side bushing, a blind side bushing, each having eccentric, axially extending bores to receive a shaft and a latch element that extends into an indentation in one of said bushings, all of which cooperate to connect structural members having misaligned fastener receiving holes, the improvement comprising: an alignment collar having an aperture that receives said shaft, said collar having a large diameter shoulder that faces and engages the work side bushing; said work side bushing having a peripheral edge perpendicular with its axially extending bore said alignment collar having a planar surface perpendicular with the axis of its aperture and larger than the peripheral edge of the work side bushing; both the peripheral edge of the work side bushing and the shoulder of the alignment collar selectively engaging for application of axial force and torque from the collar to the work side bushing, whereby the work side bushing may be adjusted with limited interference fit and the collar visually inspected for space between the periphery of the collar and the associated structural member.
Claim 5
Dependent Claim
21 words
The fastener and assembly means of claim 1 in which the work side and blind side bushings have tapered body portions.
Claim 6
Dependent Claim
21 words
The fastener and assembly means of claim 2 in which the work side and blind side bushings have tapered body portions.
