Abstract
Abstract A positioning device for positioning mating members of a turbine apparatus casing. Two threaded pins are retracted within one of the mating members before the members are placed in their assembled mated relationship. The pins are advanced after assembly to within a predetermined operating clearance of the other member to maintain the members a predetermined distance from each other.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
59 words
A casing for an axial flow turbine apparatus comprising: an inner cylinder, an outer cylinder surrounding and mating with said inner cylinder, and, means for positioning said inner cylinder with respect to said outer cylinder, said positioning means being disposed within said inner cylinder, said positioning means being adjustable after said inner cylinder is mated with said outer cylinder.
Claim 2
Dependent Claim
59 words
A casing for an axial flow turbine apparatus comprising: an inner cylinder, an outer cylinder surrounding and mating with said inner cylinder, and, means for positioning said inner cylinder with respect to said outer cylinder, said positioning means being disposed within said inner cylinder, said positioning means being adjustable after said inner cylinder is mated with said outer cylinder.
Claim 3
Dependent Claim
109 words
The casing of claim 1 wherein: said outer cylinder has a slot therein, said inner cylinder has a mating flange thereon, said flange being disposed within said slot to provide mating relationship between said inner and said outer cylinders, said flange having a threaded bore extending therethrough, said positioning means comprising a threaded pin, said pin being threaded into said bore in said flange before said flange is disposed within said slot, said pin being displaceable within said bore after said flange is disposed within said slot until a predetermined clearance between said pin and said outer cylinder disposes said flange a predetermined distance away from said outer cylinder.
Claim 4
Dependent Claim
35 words
The casing of claim 2 wherein: said bore extends axially through said flange, and, wherein abutting contact between said pin and said flange disposes said flange axially away from said outer cylinder said predetermined distance.
Claim 5
Dependent Claim
15 words
The casing of claim 3 further comprising: means for securing said pin within said bore.
Claim 6
Dependent Claim
134 words
The casing of claim 1 wherein: said outer cylinder has a slot therein, said inner cylinder has a mating flange thereon, said flange being disposed within said slot to provide mating relationship between said inner and said outer cylinders, said flange having a threaded bore extending axially therethrough, said positioning means comprising a first and a second threaded pin, said first and said second pins being threaded axially into said bore in said flange before said flange is disposed within said slot, said first and second pins being advanceable within said bore after said flange is disposed within said slot until a predetermined clearance between said fIrst pin and said outer cylinder and between said second pin and said outer cylinder disposes said flange in a predetermined axial position relative to said outer cylinder.
Claim 7
Dependent Claim
20 words
The casing of claim 5 further comprising: means for securing said first pin and said second pin within said bore.
Claim 8
Independent Claim
100 words
A device for positioning a first member relative to a second member, said first and said second members being in a mated relationship, said first member having a threaded opening therein, said device comprising: a threaded pin extending into said bore, said pin being disposed within said bore before said first and said second members occupy said mated relationship, said pins being advanceable within said bore after said first and said second members occupy said mated relationship until a predetermined clearance between said pin and said second member disposes said first member a predetermined distance away from said second member.
Claim 9
Independent Claim
100 words
A device for positioning a first member relative to a second member, said first and said second members being in a mated relationship, said first member having a threaded opening therein, said device comprising: a threaded pin extending into said bore, said pin being disposed within said bore before said first and said second members occupy said mated relationship, said pins being advanceable within said bore after said first and said second members occupy said mated relationship until a predetermined clearance between said pin and said second member disposes said first member a predetermined distance away from said second member.
Claim 10
Dependent Claim
39 words
The device of claim 7 wherein said bore extends axially through said first member and, said abutting contact between said pin and said second member disposes said first member axially away from said second member for said predetermined distance.
