Description: |
| The patent covers a screw and rack adjusting wrench. The screw has one conical shaped end with the other end riding on a pin, with a spring-loaded ball bearing. There is also a spring catch that serves as an adjustment lock.
This is an evolution from Wenger's previous patent (no. 572,185); pat. No. 837,254 is a further refinement. |
