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.

Patent Number Date Title Name City Description
188,580 Mar. 20, 1877 Improvement in wood-polishing machines James Lyman Perry Berlin, WI This patent is especially notable because it heralds the beginning of what eventually became P. B. Yates Machine Co., which was one of the largest woodworking machinery makers in the world.

908,513 Jan. 05, 1909 Multiple-board gage Burt D. Stevens Beloit, WI
913,641 Feb. 23, 1909 Multiple gage Gilbert O. Hammer Beloit, WI An ingenious gage so that a saw can be set up to do any of, say, a half-dozen different widths at a time. The gage has multiple fingers that each can be independently set to the appropriate distance from the blade. A board is butted against the desired gage and pushed forward; the other gage fingers are pushed up out of the way.

931,223 Aug. 17, 1909 Feeding mechanism for saw John P. Gates Beloit, WI "In double cut-off saws it has been usual to employ a feeding mechanism consisting of a pair of chains passing around sprocket wheels and having conveyer blocks or flights attached thereto at intervals and to corresponding links of the pair of sprocket chains, to feed or push the boards forwardly to the companion cut-off saws. Use of these machines has shown and demonstrated that the hinge pins or links of the chains not only become worn but that they wear unevenly, destroying the alinement of the pushing or feeding blocks or abutments, and causing improper and untrue sawing of the boards. To overcome this difficulty we have devised a feeding mechanism of the same general character as that outlined above but in which endless steel bands, which cannot stretch, take the place of the objectionable chains."

3,374,816 Mar. 26, 1968 Bandsaw guide John A. Alich Burlingame, CA A previous patent awarded to this inventor was assigned to Turner Machinery Co., Inc. of San Francisco. This patent here was assigned, by mesne (indirect) assignments, to P. B. Yates Machine Co. in Canada. It is plausible that the Turner company was bought out by the Yates company.
