Description: |
| The patent is an improvement to the Frederick P. Robert February 21, 1922 patent (no. 1,407,578). The patented features are the spring, and the stop which hold the jaws slightly gapped -- "in inopperative position."
Many wrenches marked with the Feb. 21, 1922 patent date correspond to this patent's features. Subsequent improvements especially applicable to larger sizes were patented by Robert Hoe in no. 1,681,184. |
