USPTO = U.S. Patent Office . Images of the actual patent can be viewed on the U.S. Patent Office web site but a special TIFF viewer must be installed with your browser in order properly work. More information on how to configure your computer to view these patents can be found at TIFF image Viewers for Patent Images.
DATAMP = Directory of American Tool And Machinery Patents . A sister site to VintageMachinery.org with information on patents related to machinery and tools. A much easier user interface than the USPTO's for finding information on machinery patents.

Patent Number	Date	Title	Name	City	Description
2,722,784	Nov. 08, 1955	Buffing head	Otto Thiel	Detroit, MI	The assignee, Midwest Supply & Mfg. Co., was established by George R. Carlson in 1947. Carlson was the son of Gustave A.

3,012,381	Dec. 12, 1961	Flat stock finishing machine	Adam Zimmerman	Birmingham, MI	In manufacturing sheet metal, finish sanding of thicknesses less than 0.026 inches (0.66 mm) caused buckling of the sheet. The method previously used was to have pinch rollers push a web of sheet metal below a rapidly driven abrasive belt, with an idler roller ("billy roll") pressing the sheet metal against the abrasive belt. The pushing of the pinch rollers before the belt caused the sheet metal to buckle when pushed against the outfeed pinch rollers. The improvement is to drive the billy roll at the same speed as the pinch rolls, which is less than that of the abrasive belt. With this improvement sheet metal as thin as 0.012 inches (0.30 mm) can be successfully finished.

3,144,777	Aug. 18, 1964	Compound motion adapter for buffing machine	John G. Hackert	Birmingham, MI	Improvement to patent 3,099,902 to retrofit a reciprocating motion to the polishing or buffing spindle.

3,220,146	Nov. 30, 1965	Flat stock finishing machine	John Ross	Southfield, MI	Improvements to patent 3,012,381; see that patent for a description of of this machine for manufacturing thin sheet metal. See also patent 3,220,146 which is a companion to this improvement patent. The improvement is intended to avoid a problem where the leading edge of the sheet metal web contacting the abrasive belt caused a transverse region of high wear on the belt which leads to shadow lines on the rest of the web of sheet metal. The improvement shifts the axis of the billy roll relative to the forward edge of the abrasive belt as the stock advances so that the leading edge of the sheet metal will ride up on the billy roll ahead of the belt.
3,224,147	Dec. 21, 1965	Method of finishing flat stock	John Ross	Southfield, MI	This patent is a companion to patent 3,220,146.
