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.

798,519 Aug. 29, 1905 Adjustable band-saw Edward Tiers Manning Knoxville, TN "The present invention relates to band-saws where the frame carrying the saw-blade is adjustable, so as to set the saw at different oblique positions in order to adapt it to cut bevels and any desired angles. It is desirable where the saw-blade is adjustable in this way that the work-supporting table through which the saw passes should also be adjustable to follow the different positions of the saw; and the present invention relates specifically to means for effecting the adjustment of the saw-carrying frame and also to means for automatically effecting an adjustment of the table to correspond with the different positions of the saw."
