Abstract
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 and inwardly directed bends formed therein in an alternating pattern 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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
154 words
A joint construction comprising: a plurality of work pieces having aligned holes therethrough of a nominal first prescribed diameter; a fastener through said holes having a second nominal working diameter; a sleeve member between said fastener and said work pieces within said holes including a resilient tubular metal side wall having a predetermined thickness, said side wall having formed therein a plurality of outwardly directed bends and a plurality of inwardly directed bends, said outwardly and inwardly directed bends alternating to form external ridges and valleys and internal ridges and valleys, the resiliency of said side wall urging said external ridges toward a substantially constant maximum unrestrained outside diameter along the length of said side wall a prescribed amount larger than said first prescribed diameter of said holes and urging said internal ridges toward a substantially constant minimum unrestrained inside diameter a prescribed amount smaller than said second nominal working diameter of said fastener.
Claim 2
Dependent Claim
154 words
A joint construction comprising: a plurality of work pieces having aligned holes therethrough of a nominal first prescribed diameter; a fastener through said holes having a second nominal working diameter; a sleeve member between said fastener and said work pieces within said holes including a resilient tubular metal side wall having a predetermined thickness, said side wall having formed therein a plurality of outwardly directed bends and a plurality of inwardly directed bends, said outwardly and inwardly directed bends alternating to form external ridges and valleys and internal ridges and valleys, the resiliency of said side wall urging said external ridges toward a substantially constant maximum unrestrained outside diameter along the length of said side wall a prescribed amount larger than said first prescribed diameter of said holes and urging said internal ridges toward a substantially constant minimum unrestrained inside diameter a prescribed amount smaller than said second nominal working diameter of said fastener.
Claim 3
Dependent Claim
184 words
A joint construction comprising: a plurality of work pieces having aligned holes therethrough of a nominal first prescribed diameter; a fastener through said holes having a second nominal working diameter; a sleeve member between said fastener and said work pieces within said holes including a resilient tubular metal side wall having a predetermined thickness, said side wall having formed therein a plurality of outwardly directed bends and a plurality of inwardly directed bends, said outwardly and inwardly directed bends alternating to form external ridges and valleys and internal ridges and valleys, the resiliency of said side wall urging said external ridges toward a substantially constantly decreasing maximum unrestrained outside diameter from one end of said side wall to the other and urging said internal ridges toward a substantially constantly increasing minimum unrestrained inside diameter from said one end of said side wall to said other, the smallest maximum unrestrained outside diameter being a prescribed amount larger than said first prescribed diameter of said holes and the largest minimum unrestrained inside diameter being a prescribed amount smaller than said second working diameter of said fastener.
Claim 4
Dependent Claim
184 words
A joint construction comprising: a plurality of work pieces having aligned holes therethrough of a nominal first prescribed diameter; a fastener through said holes having a second nominal working diameter; a sleeve member between said fastener and said work pieces within said holes including a resilient tubular metal side wall having a predetermined thickness, said side wall having formed therein a plurality of outwardly directed bends and a plurality of inwardly directed bends, said outwardly and inwardly directed bends alternating to form external ridges and valleys and internal ridges and valleys, the resiliency of said side wall urging said external ridges toward a substantially constantly decreasing maximum unrestrained outside diameter from one end of said side wall to the other and urging said internal ridges toward a substantially constantly increasing minimum unrestrained inside diameter from said one end of said side wall to said other, the smallest maximum unrestrained outside diameter being a prescribed amount larger than said first prescribed diameter of said holes and the largest minimum unrestrained inside diameter being a prescribed amount smaller than said second working diameter of said fastener.
Claim 5
Dependent Claim
16 words
The joint construction of claim 1 wherein the material of said sleeve member is stainless steel.
Claim 6
Dependent Claim
23 words
The joint construction of claim 1 wherein said sleeve member includes an annular head flange at one end of said tubular side wall.
Claim 7
Dependent Claim
18 words
The joint construction of claim 1 wherein said predetermined thickness of said tubular side wall is .006-.016 inch.
Claim 8
Dependent Claim
29 words
The joint construction of claim 1 wherein said bends extend circumferentially about said side wall and lie in a plane generally normal to the centerline of said sleeve member.
Claim 9
Dependent Claim
29 words
The joint construction of claim 6 wherein said tubular side wall of said tubular member terminates at one end so that said bends define an inwardly tapering flange thereat.
Claim 10
Dependent Claim
51 words
The joint construction of claim 7 wherein said sleeve member includes an annular head flange integral with that end of said tubular side wall opposite said inwardly tapering flange, and wherein said tubular side wall is made of stainless steel having a predetermined thickness along the length thereof of .006-.016 inch.
