Abstract

720,660. Testing hardness of materials. MACDOUGALL, D. Feb. 3, 1953. No. 3038/53. Class 106 (2). An instrument for testing the hardness of materials comprises a liquid-filled cylinder 10 having a shank extension 11 for enabling the instrument to be used in a conventional drill stand, a piston 12 in the cylinder 10, the piston 12 being attached to a rod 15, carrying an indenter 19, calibrated micrometer screw means for applying pressure to the liquid within the cylinder 10, and a pressure gauge 21 connected to the cylinder 10. The shank extension 11 is tapered and the indenter 19 may be a diamond, a steel ball, or if rubber is being tested, a member with a flat circular end. The cylinder 10 may be filled with lubricating oil or glycerine. The micrometer means 29 operates a plunger 23.
