1,603,894 Oct. 19, 1926 Clamp screw for saw swages Frederick K. Benedict Big Rapids, MI "This invention relates to saw swages of that class in which a head comprising a piece of metal of cylindrical or other suitable shape is formed with a slit to receive a saw blade and has a threaded hole therein at right angles to the plane of the slit. In such swages a clamping screw is inserted in the threaded hole, and is tightened to clamp the saw, or loosened to release it, usually by a handle secured to a shank formed on the outer end of the screw... The present invention is found in my novel construction of the slightly articulated joint by which the saw-engaging end-member or cap is joined to the threaded body of the screw."

2,249,743 Jul. 22, 1941 Saw sharpening apparatus Elroy J. Bucknam ON, Canada This patent is notable because it introduced a new design of handheld sharpening machine for inserted-tooth circular sawblades that dominated the industry even 60 years later. The 2005 specification for patent 6,958,004 says the following: "Over the years, many devices have been used to sharpen the teeth of the saws. The most popular saw grinders typically employ a power-driven rotary grinding wheel mounted on a grinder carriage. Such devices are well known in the art; however, there have been no significant advances therein for some time. U.S. Pat. Nos. 2,249,743, 2,439,279, 2,651,219, 3,880,019, and 4,711,142 each relate to hand-held, motor driven saw blade sharpeners. Of these devices, only the grinder disclosed in U.S. Pat. No. 2,249,743 and the improvements thereto are readily available and commonly used in the industry today. The most popular of these improvements is a saw sharpener referred to as the 'Jockey Grinder,' produced by Hanchett Manufacturing in Big Rapids, Mich."

Manting Big Rapids, MI "The present invention relates to a magnetic dial chuck feeder mechanism for the very rapid and effective continuous feeding of piston rings or similar rings between grinding wheels which continuously operating at high speed, serve to simultaneously grind the opposite sides of the castings..."
This patent is referred to in a number of subsequent patents for similar inventions. The assignee company was established in 1948 by Ralph V. Hanchett and two sons-in-law; Hanchett had earlier established Hanchett Swage Works. In 1970, Hanchett Magna-Lock was renamed to Magna-Lock Corp., and then in 1974 the company was acquired by Hitachi Metals America, Ltd., and renamed to Hitachi Magna-Lock Corp. In 1985 a former employee purchased the lift-magnet and permanent chuck lines to form Magnetic Specialties Corp.; the remaining products were purchased by Mattison Machine Works. Mattison Machine Works failed in 1997 and the assets were acquired by DeVlieg-Bullard, who in that same year sold the magnetic products to Centro-Metalcut, Inc. In 2002, Tri-CAM, Inc., was established and took over all products from Centro-Metalcut. In 2007, Tri-CAM went under; Magna-Lock USA, Inc., was created to continue the Magna-Lock product line. In 2010, Magnetic Specialties (remember them, from 1985?) went under and its product lines were picked up by Magna Lock USA, Inc.
