Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
89 words
An end cap for use with a tubularly shaped flexible element comprising: a flanged hub tapered substantially throughout its length and having a plurality of spaced axially aligned convex grooves; and a corrugated sleeve axially aligned with and spaced radially away from said tapered hub to define a generally divergent and undulating annulus for rEceiving the flexible element, said sleeve having one end flared radially outward and the other end attached to said flange in such a manner to hold said sleeve in juxtaposed axial alignment with said hub.
Claim 2
Dependent Claim
89 words
An end cap for use with a tubularly shaped flexible element comprising: a flanged hub tapered substantially throughout its length and having a plurality of spaced axially aligned convex grooves; and a corrugated sleeve axially aligned with and spaced radially away from said tapered hub to define a generally divergent and undulating annulus for rEceiving the flexible element, said sleeve having one end flared radially outward and the other end attached to said flange in such a manner to hold said sleeve in juxtaposed axial alignment with said hub.
Claim 3
Dependent Claim
25 words
An end cap as set forth in claim 1 and further including means on said hub for aligning said hub axially with said corrugated sleeve.
Claim 4
Dependent Claim
24 words
An end cap as set forth in claim 1 and further including means for adapting the sleeve and end cap to a rotatable shaft.
Claim 5
Dependent Claim
31 words
An end cap as set forth in claim 1 wherein the maximum diameter of the tapered hub is a predetermined amount greater than the minimum internal diameter of the flexible element.
Claim 6
Dependent Claim
40 words
An end cap as set forth in claim 1 wherein one end portion is flared radially outward, curled and crimped radially inward around said flange in such a manner to hold said sleeve in juxtaposed axial alignment with said hub.
Claim 7
Dependent Claim
88 words
An end cap for use with a tubularly shaped flexible element comprising: a flanged tapered hub having a plurality of spaced axially aligned grooves, said flange having a fluted circumferential edge; and a corrugated sleeve axially aligned with and spaced radially away from said tapered hub to define a generally divergent annulus for receiving the flexible element, said sleeve having one end flared radially outward and the other end attached to said flange in such a manner to hold said sleeve in juxtaposed axial alignment with said hub.
Claim 8
Dependent Claim
88 words
An end cap for use with a tubularly shaped flexible element comprising: a flanged tapered hub having a plurality of spaced axially aligned grooves, said flange having a fluted circumferential edge; and a corrugated sleeve axially aligned with and spaced radially away from said tapered hub to define a generally divergent annulus for receiving the flexible element, said sleeve having one end flared radially outward and the other end attached to said flange in such a manner to hold said sleeve in juxtaposed axial alignment with said hub.
Claim 9
Dependent Claim
55 words
An end cap as set forth in claim 6 wherein said flange has at least the same number of flutes at an angular spacing substantially equal to the spacing of the corrugations and wherein a portion of the corrugations partially extend into a portion of the flutes to further interlock said flange and corrugated sleeve.
Claim 10
Dependent Claim
107 words
An end cap for use with a tubularly shaped flexible element comprising: a flanged tapered hub having a plurality of spaced axially aligned grooves; and a corrugated sleeve axially aligned with and spaced radially away from said tapered hub to define a generally divergent annulus for receiving the flexible element, the number of axial grooves corresponding to the number of corrugations and the radially inward extending portions of the corrugations in radial alignment with the grooves, said sleeve having one end flared radially outward and the other end attached to said flange in such a manner to hold said sleeve in juxtaposed axial alignment with said hub.
Claim 11
Dependent Claim
107 words
An end cap for use with a tubularly shaped flexible element comprising: a flanged tapered hub having a plurality of spaced axially aligned grooves; and a corrugated sleeve axially aligned with and spaced radially away from said tapered hub to define a generally divergent annulus for receiving the flexible element, the number of axial grooves corresponding to the number of corrugations and the radially inward extending portions of the corrugations in radial alignment with the grooves, said sleeve having one end flared radially outward and the other end attached to said flange in such a manner to hold said sleeve in juxtaposed axial alignment with said hub.
Claim 12
Dependent Claim
143 words
An end cap adapted for use with a tubularly shaped flexible element having an internal diameter, said end cap comprising: a hub tapered substantially throughout its length and having a plurality of spaced axially aligned convex grooves, the largest portion of the tapered hub having a diameter that is larger than the nominal inside diameter of the flexible element; a corrugated sleeve axially aligned with and spaced radially away from said tapered hub to define a generally divergent and undulating annulus with the hub for receiving the flexible element; and means for attaching the sleeve to the hub in such a manner to hold said sleeve in juxtaposed axial alignment with said hub; whereby the tapered hub in combination with the corrugated sleeve flare end portions of the element radially outward in undulating fashion securing the hub and sleeve to the flexible element.
Claim 13
Dependent Claim
143 words
An end cap adapted for use with a tubularly shaped flexible element having an internal diameter, said end cap comprising: a hub tapered substantially throughout its length and having a plurality of spaced axially aligned convex grooves, the largest portion of the tapered hub having a diameter that is larger than the nominal inside diameter of the flexible element; a corrugated sleeve axially aligned with and spaced radially away from said tapered hub to define a generally divergent and undulating annulus with the hub for receiving the flexible element; and means for attaching the sleeve to the hub in such a manner to hold said sleeve in juxtaposed axial alignment with said hub; whereby the tapered hub in combination with the corrugated sleeve flare end portions of the element radially outward in undulating fashion securing the hub and sleeve to the flexible element.
Claim 14
Independent Claim
79 words
A method of making an end cap comprising the steps of: forming a flanged hub tapered substantially throughout its length and having a plurality of spaced convex axial grooves; corrugating a major portion of tubing of predetermined length and diameter; flaring both end portions of the tub radially outward; and curling and crimping one end portion around the flange in such a manner to position the corrugated sleeve radially away from and in substantially axial alignment with the hub.
Claim 15
Independent Claim
79 words
A method of making an end cap comprising the steps of: forming a flanged hub tapered substantially throughout its length and having a plurality of spaced convex axial grooves; corrugating a major portion of tubing of predetermined length and diameter; flaring both end portions of the tub radially outward; and curling and crimping one end portion around the flange in such a manner to position the corrugated sleeve radially away from and in substantially axial alignment with the hub.
