"Vintage Machinery" entry for J. P. Grosvenor.
Description:
This appears to be the first commercially-available tilting-arbor tablesaw, as evidenced by ads in Scientific American and Manufacturer & Builder. See also patent 96,224.

The innovations are a sliding journal-box for the saw-arbor, which moves to adjust the depth of cut; and a miter gauge that flips up into position, or down out of the way.
