Abstract
A vernier caliper includes a main beam body consisting of two round rods parallel to each other and connected together at one end by a jaw, and at the other end by a rear frame. A vernier is supported freely and slidably on the rods. The rods can be hollow and can have their respective ends inserted into openings of the jaw and rear frame and secured in the openings with adhesive, solder, or screws. A rack can be formed on one of the rods to drive, for example, a dial indicator, and graduations can be provided on a rod to read the measurement taken with the vernier. This construction provides a more accurate vernier caliper which can be precisely assembled without grinding, for example, jaw faces, after assembly to calibrate the caliper.
