Description: |
| The handle can swivel in relation to the plane of action of the ratchet. The ratchet body and other cast portions of known examples appear to be made of bronze or other yellowish alloy. The handle and extension bars, etc. are hollow square steel tubing. Different models are named "Silver King," "Auto Queen," or are marked only with the March 15, 1910 patent date.
The wrench sets also incorporate features of Miller's parallel patent (no. 952,435) and shanks, sockets and couplers described in Miller's earlier patents (nos. 845,716, 845,717, and 853,930). |
