Abstract:
A torque wrench comprising:an elongated torque input beam having a handle end and a work end,a work-engaging head rotatably carried by said input beam at the work end thereof,an elongated output beam disposed substantially parallel to said input beam and having an output end fixed to said head for rotation therewith and an input end,a bias mechanism coupling said input beam to the input end of said output beam and resiliently urging said input end to a neutral position relative to said input beam while accommodating continuous movement of said input end from said neutral position a distance which is a function of the amount of torque applied,said bias mechanism including two springs respectively engaging opposite sides of said output beam and respectively urging it in opposite directions, andan indicator responsive to movement of said input end from said neutral position for providing an indication of torque applied.
