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.
A set of sine bar gage elements for use in conjunction with a sine bar unit of predetermined length having a surface thereon adapted to support an article to be marked, cut, milled or the like at a selected angle with respect to a reference plane, each said element being marked with the number of an angle, said elements being adapted to be disposed between the reference plane and one end of said sine bar unit and having a height serving to elevate said one end with respect to the other to dispose said surface at an angle with respect to the reference plane corresponding to the number of the angle as marked on said element disposed beneath said one end of said unit, said set including a carrying tray for holding each of a predetermined number of said gage elements forming said set, said tray including a base of predetermined thickness, openings formed into said base dimensioned to snugly receive each of said gage elements of said set, and vent openings coupling the bottoms of said first named openings to the surrounds when the elements are disposed within said first named openings to prevent the gage elements from being retained by vacuum within the first named openings.
A carrying tray for holding each of a predetermined number of gage bar elements forming a set thereof, said tray including a base of predetermined thickness, openings formed into said base to snugly receive each of the gage elements of the set, and vent openings coupling the bottoms of said first named openings to the surrounds when the elements are disposed within said first named openings to prevent the gage elements from being retained by vacuum within the first named openings.
