The focus of this patent is on the steeper pitch and deeper threads (apparently made possible by its overall taper) of the double threaded lead screw. In addition to the location of the threads being aligned with the cutting lips, they also extend down into the body of the bit for a short distance. Researcher Geoff Emmes reports a couple of bits in Australia branded "Cox's Patent" and made by Wm. Marples & Sons of Sheffield, England. There is no mention of these bits in any Marples catalogue issued in Britain so it seems this auger was produced only for the Australian market. Geoff reports a couple other examples of this patent in Australia, one branded Ridgeway and the other branded Mathieson; neither mention Cox but have the patent lead screw.

Manufactured by House Cold Tire Setter Co. - St. Louis MO

An example of this patent tenon cutter is reported. Other than the patent date (on the end of the adjusting screw) and scale markings the only text is "The Kelly Jr." The inventor owned and operated the House Cold Tire Setter Co., and searching on that name uncovered a 1912 ad for the Kelly Jr. hollow auger from the House Cold Tire Setter Co. Note that this ad is from before the patent application so this patent is for an improved version that nevertheless strongly resembles the device shown in the ad.

Manufactured by Otis A. Smith - Rockfall CT

The first of four patents issued to Fales on a combination plane. The other utility patents are 295916 and 348198; and there is one design patent for a V-blade D18381 to fit this plane. The instruction sheet for a Fales Patent Variable Bench Plane states "constituting Carpenter's Plow, Dado, Filletster, Matching, Sash, Snipe Bill, Case Molding, Chamfer, Quarter Rounds, Nosing, and V Planes, etc., etc. This tool combines over EIGHTY DIFFERENT WOOD-WORKING PLANES, forming a very complete, economical, and low price Set of Tools." They sold for $19.25 in 1884 and for $34.50 in 1889. Otis Smith contracted with Fales to produce this plane. They were sold until 1917, but evidently had a rocky start as Roger Smith in PTAMPIA1 reprints a letter from Otis Smith to a Mr. C. C. Crossely in Danbury CT, "This is the slowest sale article I ever had anything to do with. There may be better times but I see no indication of it. Mr. Fales thinks the only way to sell is to get agents that are located to canvas. - I am sick of the whole thing but have put out so much money in it that I must stick a while longer."
