Abstract

595,727. Linear - dimension gauges. JONES, W. E. Jan. 23, 1945, No. 1779. [Class 106 (ii)] In a hand held calliper gauge for measuring external diameters of the type comprising a fixed and a movable anvil and wherein the movable anvil has lever means for bringing the movable anvil into contact with the workpiece, the movable anvil is formed with a slot which is engaged by one end of the controlling lever. The gauge comprises a body 5, a fixed anvil 7 and a spring-controlled movable anvil 6 slidably mounted in a vertical bore 5b. Towards the upper end of this anvil is a slot 6b engaged by one end of an even-armed lever 14, the other end of which engages the plunger 8a of a dial indicator 8. The lever 14 is fixed to a spindle 15 which in turn is fixed to one end of the operating lever 16. In a modification shown in Fig. 3, the lever 14 is loosely mounted on the spindle 15 which is provided with an arm 14a which engages the slot 6b. In a further modification, the plunger of the dial is in direct contact with the movable anvil.
