Description: |
| Machine translation edited from ESPACENET: [Round-headed wrench] "in which the adjustable jaw can be adjusted precisely to the respective jaw width by avoiding any toothing and automatically locks in the given clamping position. The guide leg of the adjustable jaw is held immovably in every clamping position on its slanting back by means of a covered spring wedge piece and can be released from the outside with a jerk."
Marketed as "VELOX;" see entry for matching U.S. patent 1,382,248 for English ad example, photo, etc. This patent (granted in several European countries & the U.S.) is noted as end note 21, vol. 2 of THE ADJUSTABLE SPANNER, by Ron Geesin.
Note: Some machine translations will transliterate Schäfer into Schaefer. |
