hello everyone
i am looking for information on a spanner i had left to me by my deceased brother.
it is engraved with original clyburn number 1 and from what i can gather is around 150 years old.
any information on this would be appreciated.
thanks mr c pass {uk}

Any photos?

do you have an email address i have 4 pictures but the files too large to post

is it a serial no or a patent no?that way you may be able to identify it.
brian

Ironically, the No 2 is also engraved "The Original"

It would be interesting to see what number is on yours, I have never seen a reference to an actual patent number, tho everyone seems certain of the invention date (how?)

i think the original is on all clyburn spanners whatever number they are,

done some googling,found that the patent date is said to be-15th oct 1843.no patent number yet.

This is why I don't trust data from the net, when everyone knows something, but nobody can give a reference ;P

There were no Utility patents issued Oct 15, 1843 whatsoever.

There was a patent issued to Richard Clyburn on Sep 5th , 1843 however.

(Note: 1842 on the table is a typo, the succeeding tables are dated 1843, in sequence, and it is from the 1844 register, which is likely where the 1842 claims come from)

From: The Mechanic's Magazine, Museum, Register, Journal and Gazette, Volume 39
(google books)

PS: The actual patent number is  3

is that your anglophobia rearing its ugly head again crusty?

Just dataphobia ;P
I have also seen Sep 13 claimed ....

here are some photos of the clyburn spanner
