Scrapers? but for what?

[Billman49]

Well done - I did think that if they were scrapers they'd be good for de-coking heads & exhaust manifolds etc - I remember having the head of my old side valve (1950's) UK made Ford fairly regularly and using wire brushes on my dad's old B&D drill for the same job..

It goes to show just how similar shaped tools can be for widely varying jobs....

Look like older versions of tools I have used on a Wood Lathe, the shaft would rest on the Support and the Tip cut patterns in the wood

Into the Sixties we often "Decoked" heads and cylinders on small engines. Back in my bike shop days I spent a lot of time scraping on small bike engines. Can you imagine how caked up the exhaust ports got on small two-stroke engines?

I've had the exhaust plug up so bad from carbon on 2 cycle engines the engine wouldn't run .
Rochester products came out with a product called X66 , you ran it through the intake system to dissolve the carbon. Lead deposits were part of the problem , along with poor burning fuel.  When unleaded gas came out , decarbonizing was another lost auto service , along with valve grinds.
Those are a nice set of scrapers , I wouldn't have guessed there use , but I can see how they would be useful.

NOTE; very hard to read, but looks like "Mound Tool & S. Co. St. Louis  U.S.A.
I just googled Mound Tool & S. Co.  and it comes up with Mound Tool & Scraper Co.
1606-1608 N. Broadway,   St. Louis, Mo.   in business since 1899

today they are;  Mound Tool Co. 9301 Watson Industrial Park, St. Louis, MO
Making meat processing and packing tools,  yup, tools like knifes, hooks, scrapers, etc.
