Greetings from Monterey Bay's Historic Cannery Row !
My great grandfather, Francis Harley Davis, inventor/patent attorney delivered that steam engine. It was used to provide power to his patented Davis Calyx Drill. A hydraulic drill used for "core boring" in bedrock, strata exploration, and to take coal samples and was used to drill the 60 inch diameter holes that anchor the Grand Coulee Dam.
Many units were produced and delivered. Some had more powerfull steam engines than others. Your engine could be used for alot of things like pumping water, drilling, sawing wood, generating electricity etc... the one you have was probably used for making "water pressure" that went down into the bedrock cooling and lubricating the teeth, the shaft was turned from the surface by yet another steam engine. A 12HP steam engine drove the shaft. "Davis Calyx Drill". From the Davis Drilling Co. N.Y. City.

That lil' jenny is probably not worth very much money. They made millions of steam engines and most of them are just rusty scrap iron by now. It might be worth about ten thousand bucks??
