    Abstract: A torque wrench tester is mounted upon an adjustable bracket so that it may be changed from one angle to another with respect to horizontal. The purpose is to check torque wrenches at a plurality of positions because their calibration may vary from one to another. The embodyment shown combines two torque wrench testers of different capacities connected by common spacer bars so that wrenches of different capacities may be tested.

    Abstract: CALIBRATING APPARATUS FOR TORQUE WRENCHES AND OTHER FORCE MEASURING INSTRUMENTS. A FRAMEWORK SUPPORTS A MEANS FOR MOUNTING A TORQUE WRENCH ALTERNATELY FOR EITHER CLOCKWISE AND COUNTERCLOCKWISE APPLICATION OF FORCE. A FORCE IS TRANSMITTED TO THE TORQUE WRENCH HANDLE THROUGH A GEAR REDUCTION UNIT AND A SPROCKET AND CHAIN TRANSMISSION ELEMENTS. THE TORQUE TRANSMITTED TO THE WRENCH IS TRANSMITTED THROUGH ADDITIONAL LINKAGE TO A PLATFORM SCALE FOR COMPARISON WITH THE TORQUE WRENCH

    READING. IN ADDITION A STEEL CABLE IS PROVIDED BETWEEN THE FORCE APPLYING AND MEASURING UNITS WHICH CAN BE USED FOR A VARIETY OF TESTING PURPOSES.
