Manufactured by Davenport Tool Co. - Rochelle IL

The patent covers the processes used to assemble the parts of the handle. ABSTRACT; "A method of manufacturing hand wrenches having a relatively long handle attached at one end to a yoke pivotally carrying the housing of a ratcheting socket drive mechanism fabricates the yoke, instead of casting or forging it, and employs a separate ferrule at the joint between the handle and the yoke, the parts being held in assembled relation and rotated while during a two step operation weld metal is deposited between the ferrule and the yoke, the legs of the yoke at the same time being compressed upon the ratchet housing." Produced as the SIDE WINDER swivel head ratchet wrench. The offset in the handle and "free rotation" of the end piece would enable use as a "speed wrench." Patent nos. 1,307,485, 1,524,035, 1,888,885, 2,720,127 and 2,977,824 are cited as references.
