Abstract
An improved hollow grinder bevel angle control wherein a height-attitude coupling mechanism links the height and attitude motions of an adjustable tool-rest, and a scale on a stationary portion of the grinder cooperates with a pointer on the height-attitude coupling mechanism to indicate a relationship between bevel angle and grinding wheel radius. The coupling mechanism is implemented with a linkage mechanism that provides a wide range of tool-rest adjustment, subject to the height-attitude relationship defined by the linkage. The pointer is mounted for rotation with the linkage mechanism about its fixed pivot point, and is user-adjustable so that a dimension from the fixed pivot point to the tip of the pointer coincides with the radius of the grinder wheel. The bevel angle scale is stationary with respect to movement of the linkage mechanism, and arranged so that the tip of the pointer sweeps across the scale as the linkage mechanism is adjusted through its full range of movement. The indicia on the scale reflect the height-attitude relationship defined by the linkage mechanism, such that the indicia coinciding with the tip of the pointer denotes the achieved bevel angle. A tool-…
