Abstract:

A set of direct-reading sine bar gages has been provided in which each of the gage elements is marked with a number corresponding to the associated angle of elevation of the sine bar when that particular element is disposed beneath the sine bar. Accordingly, when the technician is seeking to elevate the sine bar to a particular angle the technician needs only to inspect the various gage elements to determine which of them is marked with a number corresponding to the angle which he desires. A carrying tray holds each of a predetermined number of gage elements forming the set. The tray includes a base of predetermined thickness with openings formed into the base to snugly receive each of the gage elements of the set. Vent openings form flow passages between the first named openings and the surrounds. When the elements are disposed within their respective openings, the vents prevent the gage elements from being locked by vacuum within their respective openings.
