Information requested

[leghorn]

I'm posting this here,because it's too big to be called a Pocket Watch, although it has more of a P/W movement than a clock works.It originally came in a leather case,now almost non-existant. The movement from what I can tell, is 15 jewels. I am posting a couple of pictures.Any information on the maker and date would be appreciated. The name on the face is "E. Caldwell", probably the name of the retailer. Any questions,please ask.

Hi Leghorn,
DRP175275 (german patent) was issued 9/22/1906. I downloaded the patent info but it is in german and I don't read it.
The US Patent 816321 was issued 3/27/1906. The patent is for an invention that allows 8 days of operation without increasing the mainspring size.
All together there are 5 PDF files, 3 german and 2 US. Email me at:
<n0fnf@sbcglobal.net >
and I will send them to you.

That looks just like what was called a 'portmanteau watch' which was held in a folding 3-part leather case by the screwed-on bezel.
However, these obtained the running time by using a barrel nearly the diameter of the movement - yours has done it by an extra wheel in the train, and a normal barrel.

Joe, thanks for those patient office files. It seems that he applied for the same patient, in two countries. Pretty neat how his patient works.

Mike, thanks for that bit of information, about what that type of Watch was called.As I stated, the case for it is long-gone.

I have one more question; the name on the movement,"A. Comman - France", is that the maker of the movement,and would it be collectable in it's present condition.
