Abstract: The drawing shows a section of an ordinary sized smelting-furnace on a scale of an inch to a foot, and represents such part thereof as is necessary to a clear understanding of my invention, which consists in a mode of introducing the air from the blowing apparatus diffusedly-without impinging upon the ignited fuel, as it does when introduced through the tuyere in the ordinary way, by which diffusion there is an essential difference in the results produced, the action of the air being, from the very commencement of its introduction, by gradual and easy pressure. Claim: The diffusing of the blast in a chamber as it enters a furnace.

The patent is for the two-piece construction of the shank and handle; this design was to be made of malleable iron. Shepard's other wrench designs were produced by Peck, Stow & Wilcox. A known example somewhat resembles the malleable iron wrenches made by O.B. North 186,185, and can be mistaken for one.

Manufactured by H. Mathews Co. - Dayton OH

The basic tool is a large pliers, with nail claw and screwdriver handle tips, wire cutter, thread dies, and a "monkey wrench" adjustable jaw wrench on the side of one jaw. One version of the tool was produced with a thumb screw through the other jaw to turn the jaws into a bench clamp. A third variant has a "hammer poll" instead of the adjustable wrench, and a 4th (shown in Devitt's OHIO TOOLMAKERS) has matching "pliers" jaws. This tool was marketed as NEVERSTAll through "become a sales agent" ads in multiple magazines, etc., and resulting direct sales.

Manufactured by Hammond Mfg. Co. - Boston MA
Assigned to Hammond Mfg. Co. - Eastport ME

Structure of adjusting means allows for screw- and quick-adjust. The quick-adjust feature is a thumb piece with an off-center bore such that 1/4 turn of the thumb piece releases grip on the main adjusting screw. A modification of that principle appears together with aspects of 646,565 and 769,605 in the HAMMOND MFG. Co. nut wrench. At the time, laws relating to business incorporation led companies to incorporate in Maine regardless of the location of their business offices and manufacturing facilities.
