Key to Links for Patent Information

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.

869,649 Oct. 29, 1907 Gage John L. Pringle ON, Canada A beautiful tool, and perhaps the culmination of the designs based on W. Brodhead's original patent (76,884). This tool uses a metal sheathed bar for wear protection, and also adds a split-bar design to allow it to be used to mark mortises.
This tool was assigned to the Union Manufacturing Company, but between when the patent was applied for and when it was granted, Union was acquired by the Stanley Rule & Level Company.
This tool was produced (a single example is known extant), but the merger of Union and Stanley probably killed the production.
