Early breechloading cannon patents

[cannonmn]

Here's something intersting to do when you are snowed or iced-in.

Go to this site:

http://www.google.com/advanced_patent_search


Where it says "all words" put in "breechloading cannon"

In the dates section at bottom, put some range you want to look in, like 1776-1870.

"Search."

cannonmn,
   Were you able to find you Mississippi Pat.s on the list of CSA pat.'s for breechloading guns?
Looking at patent's and trying to match them to something that has been produced can be difficult. My own gun was produced off the Joslyn rifle Patent and does not look alot like it in operation. It doesn't look much like the earlier version "Thayer" gun either. The same applies to the two known Hughes guns with one being exactly like the 1863 Patent drawings and the earlier one in operation being different.
   Thanks for the link. It works really well and beats trying to work with the search feature at the U. S. patent office.

Sorry I did't look.  The page I found I think was done for one state only (Alabama,) since it was done by the Birmingham public library.

I was kind of amazed while I was browsing thru them, I saw one that looked awfully familiar.  Sure enough, went and got it, and what I have has to be the patent model shown in the patent drawing.  The breech screw and carriage are missing, but now at least I have something to go on if I want to re-create them.  I'm sure I'll at least make a breech screw one of these days.  One reason I never looked for it in US patents before was that it has Beaulieu System rifling, for studded shells, which I've never seen any evidence of in the US before, to me it was always a European thing.  But here's evidence it was at least being considered here in the US.

cannonmn,
    Most certainly an interesting model. Quite a number of patents for the early breechloading guns featured the breech that would swing out of the way. I wonder how many were ever built.  The only one I have seen was built for the C.S. navy in Ga.

There were a number and we've had previous discussions on this board, which you can still find. with photos of the real things.  Usually only one full-scale firing example was built, but a number are still around today.   Someone find that discussion, maybe about a year back, and give us a link please.

The one I'm thinking of concerned Kabar's gun in NY, he mentioned it, and a friend of mine found it and took pix.  The big one looks exactly like the patent drawing, remember the spear-point-shaped take-up nuts ahead of the trunnions?

Where's Kabar?

Thanks Allen, you will see I revived that fascinating discussion since you were kind enough to locate it for me.
