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
236,968 Jan. 25, 1881 Reciprocating saw mill Theodore S. Wilkin East Saginaw, MI
259,068 Jun. 06, 1882 Machine for stretching saws Theodore S. Wilkin East Saginaw, MI Wilkin sued Milo Covel for infringing this patent. In 1891 the Circuit Court, N. D. Illinois, found in favor of Covel because this patent covered only the combination of elements, all of which were already known. Wilkin argued that the convex roller was new. The drawing does show a convex roller but its shape was never mentioned in the specification and so the court rejected Wilkin's argument and essentially ruled that the patent was meaningless.

335,168 Feb. 02, 1886 Saw-mill set-works Theodore S. Wilkin Milwaukee, WI "My invention relates to saw-mill set-works, and is designed as an improvement upon the mechanism for which Letters Patent of the United States were granted to me bearing the date the 3d day of March, 1885, and numbered 313,396. In the aforesaid patent the knees were advanced and receded by fluid-pressure from a source outside of the carriages; but in the present apparatus the movements in both directions are effected by pneumatic pressure accumulated through the operation of a pump carried upon the carriage and operated through the travel thereof."
393,802 Dec. 04, 1888 Bandsaw mill Theodore S. Wilkin Milwaukee, WI Mechanism for adjusting the upper wheel to control tracking.
D. C. Prescott's 1910 monograph, "The Evolution of Modern Band Saw Mills for Sawing Logs", says, "...in 1888 The Wilkin Mfg. Co., of Milwaukee, Wis., advertised and marketed a Band Mill designated as 'the most common sense Band Mill made.' It had overhanging wheels of wood with rubber faces.
"In one respect this mill demonstrates how easy it is for one to imagine a trouble and then spend a lot of money to correct a trouble that really has no existence.
"It was known, of course, that a band saw under stress would be inclined to gravitate to the rear. In this mill the attempt is made to prevent this and compel the saw to follow its proper path around the wheels by raising or depressing the tail end of the top wheel shaft; and in order to do this automatically a steel trolley was applied to the rear edge of the saw, closely following it, whatever its position might be; but any movement of the trolley towards the front or rear was followed by a corresponding adjustment of the tail box of the top shat. The effect of the trolley on the edge of the saw was bad; and besides that there really was no special need of any device of the kind..."
