Abstract
Abstract In a turbomachine casing divided along a horizontal joint into upper and lower casing halves, a diaphragm is supported on each side by upper and lower lugs including shoulder portions which interlock with respective upper and lower diaphragm halves. A vertical pin is inserted through each shoulder and into abutting diaphragm portions to prevent relative movement between the turbine casing and diaphragm.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
141 words
A turbomachine including an outer casing divided along a horizontal joint into upper and lower outer casing halves and further including a diaphragm within the outer casing, the diaphragm divided into upper and lower diaphragm halves within the outer casing; and, means for mounting the diaphragm halves within their respective outer casing halves comprising: upper and lower casing lugs mounted in a cutout portion on each side of the outer casing; a shoulder formed on each lug; a slot formed on each side of a respective diaphragm half, each shoulder extending into its respective diaphragm slot; at least one substantially vertical fastener on each side of the turbomachine casing, each fastener having a portion thereof positioned in at least one shoulder and another portion thereof positioned in the diaphragm whereby movement of the diaphragm relative to the outer casing is prevented.
Claim 2
Dependent Claim
