Abstract
A torque-measuring wrench that effectively and accurately translates the twist in a work-engaging member to a calibrated meter spaced therefrom through an improved elongate twist-translating member operatively disposed therebetween that maintains a fixed meter-actuating moment arm for each setting, and provides for the convenient straight line moment arm adjustment between the translating member and the calibrated meter to enable simple and accurate calibration corrections by the user to insure precise measurements commensurate with the applied turning load. The translating member is of comparatively light nonflexible construction to render such irresponsive to abnormal deflections when the prescribed manual application of the turning force is inadvertently applied during the use thereof. This is accomplished with an improved twist-translating arm and mount therefor which embodies an improved straight line moment arm that is capable of adjustable setting with the calibrated meter operating lever through a removable housing closure without dismantling any part of the wrench assembly.
