Abstract
Abstract A rotating member such as a turbine disk is provided with an axially extending retaining means such as a ring having a plurality of D-shaped, open-ended slots formed about an edge thereof. A collar embracing a generally radially extending tube is received within each contoured slot and a pair of laterally extending lips formed upon each collar receive and engage the ring therebetween, thereby limiting radial movement of the collar. A circumferentially extending groove about the inner circumference of the ring intersects each groove and receives a split locking ring to limit axial movement of the collars and tubes.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
82 words
Apparatus for attaching a tube to a member which is rotatable about an axis, comprising: retaining means integral with said member, said retaining means having a contoured open-ended slot and a groove intersecting said slot; a wear collar, of the same general shape as the slot, surrounding the tube and received within the slot, said collar having a pair of laterally extending lips receiving said retaining means therebetween; and locking means inserted within said groove for retaining said collar within the slot.
Claim 2
Dependent Claim
82 words
Apparatus for attaching a tube to a member which is rotatable about an axis, comprising: retaining means integral with said member, said retaining means having a contoured open-ended slot and a groove intersecting said slot; a wear collar, of the same general shape as the slot, surrounding the tube and received within the slot, said collar having a pair of laterally extending lips receiving said retaining means therebetween; and locking means inserted within said groove for retaining said collar within the slot.
Claim 3
Dependent Claim
38 words
The apparatus recited in claim 1 wherein said retaining means comprises a ring extending from said member and about the rotational axis thereof and having a plurality of circumferentially spaced, open-ended slots for receiving a plurality of tubes.
Claim 4
Dependent Claim
33 words
The apparatus as recited in claim 2 wherein said groove is formed along the radially inner edge of said ring and said locking means comprises a split locking ring inserted within said groove.
Claim 5
Dependent Claim
52 words
The apparatus as recited in claim 1 wherein said retaining means comprises a plurality of generally U-shaped retainers disposed in a circular array about the rotational axis of said member with the open end of each retainer comprising the entrance to a slot, and wherein a groove intersects each of said slots.
Claim 6
Dependent Claim
44 words
The apparatus as recited in claim 4 wherein each groove is formed along the radially inner edge of each retainer and said locking means comprises a band having two ends inserted within each groove, each end of the band being folded back upon itself.
Claim 7
Dependent Claim
16 words
The apparatus as recited in claim 5 wherein the ends of each band are joined together.
