Patent Number	Date	Title	Name	City	Description
188,580	Mar. 20, 1877	Improvement in wood-polishing machines	Almon Bridgman	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.

881,086	Mar. 03, 1908	Variable-speed mechanism	Burt D.

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.
913,924	Mar. 02, 1909	Feed-roll for planers	Burt D. Stevens	Beloit, WI	Improvements to patent 771,501.
931,223	Aug. 17, 1909	Feeding mechanism for saw	Harry B. Ross	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."
