Description: |
| "This invention relates to a torque indicating wrench for accurately tightening threaded elements such as, bolts, nuts, studs, screws, etc. to a uniform predetermined tightness."
"One of the principal objects of this invention is to provide the torque scale of a torque indicating wrench with a simple and highly efficient reading-retaining device which will -travel along the torque scale when force is being applied to the wrench and which will retain its maximum force position when the force is released so as to make it unnecessary for the operator to keep his eyes on the scale while exerting force on the wrench. He can make all the necessary force adjustments of the threaded element to attain the tightness desired by inspection of the position of the reading-retaining device at his convenience."
"Another object of this invention is to provide a sturdy, relatively simple, and exceedingly accurate wrench construction which will, when a preset torque is reached will give a positive, sensitive mechanical signal to the hand of the operator so that the application of force can be stopped at the exact preset point. without reference to the scale."
B.K. Sweeney Mfg. Co. produced specialty tools including torque wrenches, torque testers, etc. |
