I got a gift the other day from ettrick, it was a sweetener he said relating to a deal we worked out a while back. I had never expected any such thing so it was a surprise to me. I don't suppose it is worth a great deal of money but it certainly meant a lot to me.

Anyway, it is an Oregon Universal Depth Gage No. 540. US Patent number 2622338 says it was invented by Joseph B. Cox in 1951 and patented in 1952. Mr. Cox invented chipper chain and founded the Oregon Saw Chain Manufacturing Corporation. I choose to declare that this one in my hand is the very first one sold, (unless somebody has another one.)

It is pretty cool, it has numbers to dial in the depth and it is made of steel, very sturdy. It has great patina, almost as if it was rust blued like a muzzle loader rifle. Other than the patina, it looks brand new, no damage of any kind.

There is a small "hook" under the depth dial that engages the cutting edge, for what purpose I do not know. Mr. Cox must have thought it important as there is a find number on the patent referring to it. (#29) This picture also shows a wrinkle in the steel just left of the pin that I think came from bending the L part of the gage down to get the "hook" under the bottom leg of the gage. If the L was initially formed out at an angle, then bent into position, manufacturing would be greatly simplified. (Can you tell I like looking for clues?)

The patent text is not available on line, the patent is too old, so we will have to be content with just the drawing.

Has anyone seen or have one of these?
Thanks ettrick,
