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.

1,336,209 Apr. 06, 1920 Saw-blade Charles H. Driver Racine, WI
1,728,673 Sep. 17, 1929 Joint for abrasive belts Charles H. Driver Racine, WI The invention is an abrasive-belt joint that is very slightly thinner than the rest of the belt, so that the joint is less subject to heating and wear. The paper backing has perforations to allow it to be separated, and the backing is stepped in thickness on either side of the perforations so that two layers of adhesive tape—one narrow piece over the joint and another wider piece for further reinforcement—join the ends together while establishing that slightly thinner cross-section.
Co-assignee John D. Rowland (1863-1952) was a prominent local businessman who had made his money in banking, real estate and insurance.

The innovations are intended to make it easier to change sandpaper and also to keep the paper pulled tight on the drum, even if the paper stretches in use.yy
