Abstract
Abstract A tool for removing vanes from a jet engine compressor casing in the form of an arcuate plate having a plurality of projecting blades on one side thereof spaced apart and angulated to fit between the vanes in a jet engine together with projections on the outer end of each blade for engaging corresponding openings in the vane assembly in the jet engine compressor casing. The opposite surface of the arcuate plate is provided with an angulated socket having a rounded inner end for receiving the output member of an impact tool such as an air hammer to apply a driving force to the tool.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
71 words
A tool for removing vanes from a jet engine compressor casing comprising an arcuate member having a plurality of radially extending blades mounted on the convex side thereof, said blades on the arcuate member adapted to extend between the vanes in the compressor casing, and means on said member for rEceiving an external force, whereby said force causes said vanes to move arcuately along the inner surface of the compressor casing.
Claim 2
Dependent Claim
71 words
A tool for removing vanes from a jet engine compressor casing comprising an arcuate member having a plurality of radially extending blades mounted on the convex side thereof, said blades on the arcuate member adapted to extend between the vanes in the compressor casing, and means on said member for rEceiving an external force, whereby said force causes said vanes to move arcuately along the inner surface of the compressor casing.
Claim 3
Dependent Claim
36 words
The structure as defined in claim 1 wherein said blades on the arcuate member have axial projections thereon for reception in correspondingly spaced apertures in the base of a group of vanes in the compressor casing.
Claim 4
Dependent Claim
57 words
The structure as defined in claim 2 wherein said means on said member includes an impact receiving socket thereon, said impact receiving socket having a rounded bottom surface for engaging a correspondingly shaped impact imparting member to enable forces to be exerted on the tool at various angular relations between the tool and the impact imparting member.
Claim 5
Dependent Claim
95 words
The structure as defined in claim 3 wherein said arcuate member includes a side plate having an arcuate outer edge curved to conform generally with the inner surface of the compressor casing, said blades being rigid with and coextensive with the arcuate side plate, and an inner plate connected with the inner edges of the blades with the width of the blades being substantially equal to the width of the inner arcuate plate and the total width of the tool being substantially equal to the width of a group of vanes in the compressor casing.
Claim 6
Dependent Claim
25 words
The structure as defined in claim 4 wherein said axial projections on said blades are oriented adjacent the juncture between the blades and side plate.
Claim 7
Dependent Claim
28 words
The structure as defined in claim 5 wherein said impact receiving socket is oriented adjacent one end of the side plate and adjacent the arcuate outer edge thereof.
Claim 8
Dependent Claim
36 words
The structure as defined in claim 6 wherein said blades are angularly disposed in relation to the side plate and radiate from a common point generally conforming with the center of curvature of the compressor casing.
Claim 9
Dependent Claim
45 words
A tool comprising an arcuate member, a plurality of radially extending members on the convex side of said arcuate member, means on each radially extending member to engage a workpiece, and means on said arcuate member to receive an external force applied to said tool.
Claim 10
Dependent Claim
45 words
A tool comprising an arcuate member, a plurality of radially extending members on the convex side of said arcuate member, means on each radially extending member to engage a workpiece, and means on said arcuate member to receive an external force applied to said tool.
Claim 11
Dependent Claim
50 words
The tool as defined in claim 8 wherein said radially extending members are substantially the same length and disposed in alignment for engaging an arcuate workpiece, said means on said arcuate member including a curved surface to receive forces as the tool moves in an arcuate path along the workpiece.
Claim 12
Dependent Claim
26 words
The tool as defined in claim 8 wherein said means on each radially extending member includes a radial projection for reception in recesses in a workpiece.
