I picked up an old junker cheap on eBay, just because it intrigued me and looked like it might be pretty old.

I checked it against a couple of different type study websites, and it checks out as a Type 6 in every respect. My question is this: Both sites show that Type 6 planes were manufactured between from 1888-1892. They also show that these planes have the logo below on the iron:

I have always assumed this marking meant that the date of the patent application was April 19th, 1892. If this is the case, how could a plane made in 1888 have this marking? Am I misinterpreting the marking?

I thought pat ap’l was short for patent application…as in number rather rather than date. But I really have no basis for this : )

The simplest answer is the original cutter wore out and he walked around the corner to the hardware and picked up one of the latest on the shelf. Or, since there are no dates on those early beds, the eBay’er wanted it to look like it was old and truly an antique and put that type cutter in it. I assume the lateral adjustment lever has the appropriate stampings since you confirmed it was a Type 6, so I doubt the second answer is valid.

Shane, that makes sense.

Michael, the eBayer actually advertised the plane as vintage 1992!

Charlie, your question was interesting, so I did a little research. The patent (PAT, APL 19,92) stands for April 19th, 1892. Its for theCutting Iron with Circular Opening and Slot.

It was applied for in Jan. 08, 1891. Granted in Apr. 19, 1892.

SO to answer your original question, here is my quess.
Hyperkitten makes this statement. “some of these irons can be found with just “STANLEY” and not the patent date”

So my guess is you’ll find type 6s with and without the date, The ones made after Apr. 19, 1892 with it, the ones before Apr. 19, 1892, without it.

Don, thanks for the research. You are right… if the patent mark refers to the 1892 date, I don’t see any other possible explanation.
