Description: |
| "The general object of the invention is to provide a single tool, as briefly described hereinabove and as described in more detail hereinafter, which is capable of performing the functions of both a lifting jack handle and a tire-lug wrench." Compare another similar Walker patent -- 1,722,723. A combination crank handle and extension for Walker jacks appears in 1928 ads for WALKER No. 500 series jacks with "long folding crank handles."
The jack in the drawing resembles a form in patent no. RE17,050. |
