Gang,
I've tried to find the patent for the Stanley No. 35 block plane with no success. Does anyone know the patent number off hand or have better patent-foo than me?
Any help appreciated...

Hello, My guess is you would have to know the Type, that would put you into the year, or years, of production. Then you may be able to cross reference that year to a list of known Stanley Patents. I am guessing there are multiple patents to a Number 35, i.e., iron, frog, lever cap, etc. Regards, Lou

I've got a feeling IP is right. I can just imagine how each of those patents might cross reference to most of their planes.
If you haven't tried at DATAMP yet http://www.datamp.org/patents/search/xrefCompany.php?id=547 (http://www.datamp.org/patents/search/xrefCompany.php?id=547)
This is all (289) the patents listed there for Stanley Rule & Level.

Gary, I’m not sure there is a patent for the whole plane but rather a collection of patents for the various bits and pieces as Bill and Lou pointed out.
According to John Walters “Stanley” book the following patents applied to the no. 21 so by extension should apply to all the rest of the transitionals.
21,311, 67,398, 72,443, 173,177, 306,877, 386,509, 1,032,346
Check out Pat Leach’s site for some transitional plane history.

Gang,
Thanks for all your helpful suggestions. I'm still considering all options at getting thru to the relevant patent or patents.
That said, I found an excellent photo of a near NOS quality Stanley/Bailey No 35 plane and the original box. The stampings on the toe of the plane were crisp and clear and I was able to clearly make out the following info: "Pat. 6912". The possibilities are 1) this is a date, i.e. 06/09/12 or 2) this is a four digit patent number.
I pursued the patent number possibility 1st and ended up in Bizarro World. i.e. foreign patents on everything but planes.
Next, I searched the date possibility and found lot's of patents of stuff near that date but not on the date. I also got some warnings that patents were only issued on Tuesdays during this period and the 06/09/12 date is not a Tuesday, hence no exact matches.
Do any of you have any ideas on how I should proceed from here given the "Pat. 6912" stamping?

this is the patent you are referencing
(see description for an explanation)

Bill,
Thanks you so much. I think this is likely the patent I'm looking for.
I've got one question for you. This patent (US 1,032,346) is dated July 9, 1912. The factory stamping on the plane was June 9, 1912. Do you think it is likely a case of Stanley jumping-the-gun on the issue date? I've seen similar cases like this on other tools and other manufactures. Your thoughts...

I guess you missed this in the description on Datamp
The incorrect patent date of June 9, 1912 was marked on planes until 1922

Gary, I think this will explain the confusion.
“Patent was primarily for the brass bushing placed in the wooden stocks of transitional planes to provide a secure fastening for the frog. Was also used on the #12-3/4 rosewood bottomed scraper.
The incorrect patent date of June 9, 1912 was marked on planes until 1922.”
