Sine bar grinding wheel dresser

A grinding wheel dresser comprising a base and a column supported on the base and extending upwardly therefrom and fixed thereto,

• said column having two forwardly extending bosses fixed to its upper end,
• an arm having a first end and a second end,
• said base being fixed to said second end of said column and disposed generally perpendicular to said column and underlying said arm, said base having a lower surface adapted to rest on a magnetic table,
• said first end of said arm being received between said bosses,
• an axle extending through said bosses and through said first end of said arm,
• a cylinder fixed to said arm adjacent said second end on the side thereof adjacent said column, said arm terminating adjacent said base and providing a space between said cylinder and said column to receive a gauge block resting on said base and against said column with said cylinder disposed against the block,
• a T-shaped slot in the arm,
• said T-shaped slot extending from said first end to a position adjacent said second end,
• a slider having a follower received in said T-shaped slot and sliding on the outer surface of said arm remote from said column,
• a diamond point on said slider adapted to engage a wheel to be dressed whereby said slider can be slid up and down on said arm to move said diamond point in a path disposed at an angle to the vertical determined by the thickness of said gauge block.
