Patent number: 8919004Abstract: The present application provides for feeler gauges. The feeler gauges include a plurality of elongate measuring leaves rotatably coupled on a common axis of rotation with an elongate housing. The leaves may be manually, selectively rotatable between a “home” position wherein the leaves are substantially aligned with the housing and an “extended” position wherein the leaves are spaced from the housing.

One or more extended leaves may be used to measure the thickness of a clearance or gap. The gauges may be configured to detect, determine or measure the thickness of the leaves that are in the “home” position and/or the “extended” position, and thereby determine the total thickness of a clearance or gap measured by the extended leaves.Type: GrantFiled: December 31, 2012Date of Patent: December 30, 2014Assignee: General Electric CompanyInventors: Juntao Wu, Robert William Tait, Cheryl (Chun) Zhan, John Brandon Laflen, Steven William Wik, John Herbold, S.
