Abstract
A beam-type torquing and measuring tool having two telescoping members rotationally attached together at a first end of each, and they are relatively rotatable at the other end. One member transmits torque to the workpiece and has a pointer thereon, and the other member has a scale readable relative to the pointer to measure the torque being applied. The members have a central opening extending axially therethrough for canalization, and there may be adapters threadedly attached to the tool ends, and the scale and pointer can be read in their two diametrically opposite locations.
Claims20
A beam-type torsion applying and measuring tool comprising:
- a first and a second cylindrical member with each thereof having first and second ends and a length extending between said ends and having a central axis along said length and a hollow interior along said axis and extending completely through said members,
- said first ends being connected together for identical rotation together about said axis,
- said first end of said first member having a portion for engaging a fastener of a threaded type,
- said first member having resilient torsion-responsive beams extending between its said ends and being radially spaced from said axis for rotation about said axis of said second one of its said ends relative to said first one of its said ends upon torsional twisting of said first member, and
- a pointer and a scale respectively separately attached with said first and said second members at said second ends thereof, whereby rotation of said second end of said first member about said axis relatively rotates said pointer and said scale whereby said pointer indicates relative to said scale the amount of relative rotation between said members and thereby indicates the amount of torque being applied to the fastener.

- said first end of said first member having a portion for engaging a fastener of a threaded type,
- said first member having resilient torsion-responsive beams extending between its said ends and being radially spaced from said axis for rotation about said axis of said second one of its said ends relative to said first one of its said ends upon torsional twisting of said first member,
- a pointer and a scale respectively separately attached with said first and said second members at said second ends thereof, whereby rotation of said second end of said first member about said axis relatively rotates said pointer and said scale whereby said pointer indicates relative to said scale the amount of relative rotation between said members and thereby indicates the amount of torque being applied to the fastener, and
- said ends of said first member being threaded for respectively threaded receiving adapters connectable to said first member.
