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
1,364,356	Jan. 04, 1921	Sawing-machine	Arthur E. De Koning	Portland, OR	Invention is a tablesaw where the blade is mounted like an inverted swing saw: the work is held stationary on the table and the blade is pivoted through the workpiece. Springs are used to limit the travel in either direction and provide a restoring force to the swinging motion.
1,778,971	Oct. 21, 1930	Sawing machine	Arthur E. De Koning	Portland, OR	Improvements to the inventor's inverted-swing-saw crosscut saw (as in patent 1,364,356) to reduce cost and weight while avoiding any risk of overturning while in use: the reciprocating mass of the saw was apparently prone to tipping the base when the saw completed the cut and was returning to its home position.
1,780,176	Nov. 04, 1930	Sawing machine	Arthur E. De Koning	Portland, OR	Further improvements to the inventor's inverted-swing-saw crosscut saw, with the goal of reducing foot-pedal effort.
1,793,544	Feb. 24, 1931	Cut-off saw machine	Arthur E. De Koning	Portland, OR	The main focus of this improvement on the inventor's inverted-swing-saw cutoff saw is to make the saw swing faster through the cut then would normally be possible when just using the operator's foot power.
1,800,450	Apr. 14, 1931	Cut-off sawing machine	Orrin K. Hill	Portland, OR	Improvements to the Irvington cutoff saw to allow control of the position and speed of the oscillating mechanism.
1,808,453	Jun. 02, 1931	Combination sawing machine	Arthur E. De Koning	Portland, OR
2,007,563	Jul. 09, 1935	Mechanical movement	Arthur E. De Koning	Portland, OR	This patent covers an over-table circular crosscut saw.
2,016,799	Oct. 08, 1935	Trimmer saw	Arthur E. De Koning	Portland, OR
2,711,197	Jun. 21, 1955	Selectable latch for trimmer saw	Edwin W. De Koning	Portland, OR
2,881,811	Apr. 14, 1959	Trimmer saw machine and selective control therefor	George Haumann	Portland, OR
2,882,039	Apr. 14, 1959	Shock absorbing mechanism	George Haumann	Portland, OR
580,911	Aug. 04, 1959	Shock absorbing mechanism	George Haumann	Portland, OR
580,910	Aug. 04, 1959	Trimmer saw machine and selective control therefor	George Haumann	Portland, OR
2,905,087	Sep. 22, 1959	Printing mechanism	Edward George Farrell	Portland, OR	This print mechanism is intended for "the end printing of lumber, wherein boards are moved continuously and rapidly past a printing unit where a mark is imprinted on their ends. The rapid movement of the boards past the printing unit, the viscous nature of the ink employed, and the operating conditions generally existing in a lumber plant creates peculiar problems in printing which have been overcome quite satisfactorily by the printing mechanism of this invention."
2,918,951	Dec. 29, 1959	Control mechanism for lumber processing	George Haumann	Portland, OR
597,036	Apr. 26, 1960	Printing mechanism	Edward George Farrell	Portland, OR	This is the Canadian equivalent of US patent 2,905,087.
597,450	May. 03, 1960	Control mechanism for lumber processing	George Haumann	Portland, OR
2,958,348	Nov. 01, 1960	Circular saw	Alvin R. Bueneman	Portland, OR
3,080,969	Mar. 12, 1963	Sorting apparatus	Robert E. Blake	BC, Canada
678,591	Jan. 21, 1964	Lumber sorting apparatus	Robert E. Blake	BC, Canada	This is the Canadian equivalent of US patent 3,080,969.
