Abstract
Abstract A fastening device for cooling tubes which are uniformly distributed circumferentially about the circumference on the outlet end of a rotary tube, particularly a rotary kiln, and which are connected with the interior of the rotary tube, wherein a dish-shaped saddle is provided at at least two points on the rotary tube sleeve for receiving a cooling tube, each saddle having a closure bracket with openings therethrough for receiving bolts. The closure bracket is preferably constructed in two parts and embraces the remaining circumference of the cooling tube not disposed within the dish-shaped saddle, the closure bracket constructed is a web shaped member and arranged on edge or upright with respect to the axis of the cooling tube.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
93 words
A fastening device for cooling tubes which are uniformly distributed about the circumference on the outlet end of a rotary tube, at least two fastening devices provided in an axial spaced relationship for each cooling tube, said fastening device comprising: a dish-shaped saddle for receiving and embracing a portion of the circumference of a cooling tube, and a web-shaped closure bracket including two parts each arranged on edge with respect to the axis of the cooling tube and loosely pivotally connected to said saddle for embracing the remaining circumference of the cooling tube.
Claim 2
Dependent Claim
93 words
A fastening device for cooling tubes which are uniformly distributed about the circumference on the outlet end of a rotary tube, at least two fastening devices provided in an axial spaced relationship for each cooling tube, said fastening device comprising: a dish-shaped saddle for receiving and embracing a portion of the circumference of a cooling tube, and a web-shaped closure bracket including two parts each arranged on edge with respect to the axis of the cooling tube and loosely pivotally connected to said saddle for embracing the remaining circumference of the cooling tube.
Claim 3
Dependent Claim
54 words
A fastening device according to claim 1 wherein the pivotal connection of a closure bracket part comprises a bolt and a hole extending through the end of said bracket part in the axial direction for receiving said bolt, said hole having a greater dimension in the radial direction than the diameter of said bolt.
Claim 4
Dependent Claim
27 words
A fastening device according to claim 2 comprising cams fixed to the outer surface of the cooling tube for forming a form-lOcking connection with said closure bracket.
Claim 5
Dependent Claim
109 words
A fastening device for cooling tubes which are uniformly distributed about the circumference on the outlet end of a rotary tube, at least two fastening devices provided in an axial spaced relationship for each cooling tube, said fastening device comprising: a dish-shaped saddle for receiving and embracing a portion of the circumference of a cooling tube, and a web-shaped closure bracket including two parts each arranged on edge with respect to the axis of the cooling tube and pivotally connected to said saddle for embracing the remaining circumference of the cooling tube, adjacent ones of said saddles arranged offset with respect to each other in at least two rows.
Claim 6
Dependent Claim
109 words
A fastening device for cooling tubes which are uniformly distributed about the circumference on the outlet end of a rotary tube, at least two fastening devices provided in an axial spaced relationship for each cooling tube, said fastening device comprising: a dish-shaped saddle for receiving and embracing a portion of the circumference of a cooling tube, and a web-shaped closure bracket including two parts each arranged on edge with respect to the axis of the cooling tube and pivotally connected to said saddle for embracing the remaining circumference of the cooling tube, adjacent ones of said saddles arranged offset with respect to each other in at least two rows.
Claim 7
Dependent Claim
51 words
A fastening device according to claim 4, wherein adjacent offset ones of said saddles extend circumferentially so as to overlap each other as viewed in the axial direction, and comprising at least one web plate in the area of such overlap extending in the axial direction and connecting said adjacent saddles.
Claim 8
Dependent Claim
55 words
A fastening device according to claim 4, wherein said saddles each extend circumferentially so that adjacent saddles overlap as viewed in the axial direction of the rotary tube, and wherein the pivotal connection of adjacent closure bracket parts include a common bolt extending through such adjacent parts and the overlapping portions of said adjacent saddles.
