Patent search

[STP]

Tried to locate a patent from the 18oo`s...fruitless. Suggestions?

we had even the sketchiest details.

Even the patent office's search hasn't loaded in the early stuff.

I think you have to go to the Patent office in DC and do a manual search of the archives. A lot of it isn't online.

STP,
It is a bit of drudgery, but if you search similar modern (post 1978) patents, you may find the referenced patents to contain your patent. If you have the ccl, you can narrow the dates to find a smaller list to search.
How much information do you have to start with? What do you seek?
My wife gave me a 2 847 895 (of August 1958) for Christmas, and on the last page there are 13 references dating back to 1883 to look at and the ccl/86/23 and 86/36 to advanced search for similar items. You can narrow the search by date by using the old trial and error to narrow down the time span. The on line list claims 1790 to present by number, and 1978 to present with much more ease of recovery.
Part of the problem doing the search is that the "misses" are so interesting that they lead me off on to paths away from the search, and far into the night. But then self-discipline has avoided me all my life.
By the way, If you find a powder trickler patent, I'd be glad to see it.
Cheers from Darkest California,

university library...

you need to contact them and see if they have the books...before the internet, they would buy books with patents in them...

Contact the Linda Hall Library in Kansas City. This is the biggest technical
library in the US, and has a LOT of patents. I have used it for research,
in person, for years. Don't know what they can do long distance, tho.

The library it is! Will seek the assistance of my friends at Cornell University.
I want to view Dr. Maynard`s patents up to 1859.
Geo. Layman`s book has raised more questions than it answers...
