Abstract
A gage block is designed as a stepped sine block to produce commonly used angles when used with a conventional sine bar without the use of conventional gage blocks. Reference surfaces parallel to one or more bases are provided to produce the desired number of commonly used angles.
Claims12
A combination gage block and sine bar for setting up a plurality of commonly used angles comprising:
- said gage block having a planar base and a plurality of planar reference surfaces parallel to said base at different distances from said base;
- and
- said sine bar having a measuring surface for engaging a respective one of said planar reference surfaces to establish a different reference angle for different ones of said reference surfaces;
- wherein at least one of said reference surfaces extends beyond a projected area of said base.

A gage block for use with a sine bar to set up a plurality of commonly used angles comprising:
- a first planar base;
- a first plurality of planar reference surfaces parallel to said first base at different distances from said first base to establish a different reference angle for different ones of said reference surfaces when used with said sine bar;
- a second planar base normal to said first planar base;
- a second plurality of planar reference surfaces parallel to said second base at different distances from said second base to establish a different reference angle for different ones of said reference surfaces when used with said sine bar;
- and
- connecting surfaces for joining said reference surfaces of said first and second planar base both to their respective parallel planar bases and to other said parallel reference surfaces, some of said connecting surfaces which join parallel reference surfaces of a said planar base also serve as reference surfaces when said gage block is placed on the other said planar base.
