Description:
In this improvement on pat. no. 743,360 there is a spring and ball bearing at each end of the adjusting worm, and the adjustment lock feature compresses the springs rather than bearing on the outside of the adjusting worm.

The YEMCO (York Electric and Machine Co.) ball bearing wrench is based on these patents.
