Espacenet patent
Report data errors or omissions to steward Stan Schulz
Description:
Ratchet action accomplished by opposite facing sets of teeth on "handle" portion and two "tool driver" portions that swivel on a common center shaft. The patent includes a supplemental crank handle.

The "FERRET" ratchet spanner based on the patent did not include the supplemental crank handle; the "tool driver" portions fit a set of tubular steel wrench sockets.

Earliest 1910 trade announcements listed production by County Chemical Co. Ltd. (Birmingham); subsequent production by ACCLES & POLLOCK, Ltd. continued for a least a decade.

The patent # used in DATAMP represents the year of registration and the patent # (with "leading zeros" interposed to make the number total nine digits). This patent is #6,435 of the year 1910.
