Description:
Improvement to the design in patent no. 2,125,945. As with some other "war-time" patents, free use for government purposes is included in the specifications.

The main "bar" of the wrench handle is divided into parallel square "leaves." The relative movement of the leaves when the wrench is operated is shown by a dial indicator.

The patent number appears on an APCO-MOSSBERG TORQUE TOOL "deflection beam" type torque wrench.
