GRYP Ratchet Spanner - edited (FLICKR)
Description:
Modification to the design in GB-190401868 where the effective angle of the head and jaws is altered by re-positioning the two handle sections. Rack teeth in the handle sections mesh to hold the angle adjustment. U.S. patent 912,507, German patent DE-194499 and French patent FR-371433 show the same handle structure with an adjustable jaw "head." That form with "CLYBURN" type head and adjustable jaw was produced as the GRYP spanner by F.M. Russell and Co.
