    Dr Jon, I believe these were called "Bean Pots". I have serial 2E12656. I think they were used for surveying.

    That is my belief also but they might also be useful for bodybuilding if worn as wrist watch, or even a fanny pack

    Well, don't visit the board for a while, and look what happens. A fun new forum shows up!

    Instead of posting my chronometers, here's a link to my John Bliss virtual museum with my Bliss chronometers: http://blisschron.org/

    SN 4E009 was one of two civilian 221's owned by a family operating two tuna boats on the west coast. This is likely why the serial numbers match on the chronometer and inner and outer boxes. It has been in my collection since 1996.

    I wonder if their fishing took them across the date line. It was my understanding that the date line service was what led to the 221 design.

    Here is mine. J/5816 chronometer by McGregor of Glasgow and Greenock, movement No. 5763 (possibly by Johannsen). Double auxiliary of Poole (for extreme cold) and Eiffe (for extreme hot). Fancy coromandel box by George Thompson of Hull. With carrying case.

    Bought by the Admiralty in 1916 and assigned to HM tug "Golden Crown". Documented in Sidney, Freetown and Gibraltar.

    Very nice and complete. :coolsign: The Eiffe auxiliary looks a lot like Airy's bar except that there is no bar to turn it on. Can someone describe the theory of operation of the Eiffe?

    Re: Marine Chronometer Gallery

    Two symmetric springs are screwed to the internal part of the balance rims (corresponding to the timing screws). These springs have additional weights at their free extremities. With medium or low temperature the balance rims do not touch the free extremities of the internal springs. When the balance rims contract in high temperature, at a certain point they come in contact with the springs and start carrying the two weights toward the center of the balance, causing an additional decrease in the balance inertia. (I hope my English is understandable...)

    Hi Tom,

    Marco's explanation is excellent. The basic concept is the same as Molyneux', and Airy knew of both more or less at the same time, but it was Molyneux who secured the patent. See page 181 of Gould.

    Regards,

    Graham

    Re: Marine Chronometer Gallery

    In Airy's implementation, there is no "middle temperature" effect, it just changes the "set point" for the compensation to adapt to average heat or cold. The weights are always in contact with the inner side of the rim.

    Those weights out there at the end of a light spring seem like they would be subject to centrifugal error which would harm isochronism. i.e. their average radius would change with amplitude.

    I guess I need to sit down and read Gould again.

    Hi Tom,

    This was in the context of Sir George Airy's rôle as Astronomer Royal rather than as an inventor himself.

    Hi Alan,

    I see both text and pictures here on my browser (Google Chrome) so I don't know what to tell you. Are you signed in? Maybe try a different browser to see if your results change?

    It just occurred to me that you may not be able to read my note here, so I'll PM you! lol

    Tom - Allan has also posted the same problem here

    Roskells of Liverpool and London

    It looks as if he has been hitting his keypad, almost at random, possibly because he doesn't see the characters - I wonder if it is something to do with an incompatible character set on the browser he is using.

    I am sure it is very frustrating for Allan. I see some unlauts in his random typing so I presume he is using a German keyboard. I wonder if his isp may object to something on our site and is trying to protect him?

    If he is using a high contrast display, the text color may fall under some threshold and render as white on white also.

    He also says he cannot see the login indicator unless he hovers over it, which may be a clue.

    Here is a wonderful chronometer circa. 1860 built by Charles Frodsham for the Allegheny Observatory located at Pittsburgh, Pa. It is in a really nice figured box made of rosewood and has a 24 hour silvered dial. The dial is marked with the famous address of 84 Strand,London. It is also of the break circuit design. Derek Roberts writes in his book "English Precision Pendulum Clocks" that in addition to Frodsham's astronomical regulator clocks, (he) "was heavenly involved in chronometer design,caring out research into quick trains,balances and middle temperature compensation among-st several other matters" This chronometer and its precision clock were both timed to sidereal rate and were used in the distribution of accurate time to the city of Allegheny, Pittsburgh and much of the Pennsylvania railroad as well as to celestial navigate the telescopes located at the observatory. I also thought I would include the Frodsham regulator in these pictures. (credit Louis Coban,Allegheny Observatory for the first 3 pictures)

    Here is an early Bond marine chronometer with a really great history of service with the U.S. Navy. While it is pictured in a thread on its story I just wanted to place it in the picture gallery where I think it belongs. Completely overhauled and in great working condition its second generation box has been restored to "like new". This chronometer is heading to a museum in its future.

    When I was researching my own Mercer chronometer I learned that in 1985 the company had ceased making these instruments, they had produced around 31,000 pieces,more than any single manufacture. If that fact wasn't impressive enough some experts feel that their production is nearly 1/3 of all marine chronometers ever produced. I recently reported that the Mercer company is now back producing very high end marine and table chronometers under the leadership of Joel Mercer the 5th generation of family to head the company. Here is their "Shackleton Epic" marine chronometer which commemorates the famous British explorer, Sir Ernest Shackleton's 1916 crossing of Antarctica and its 2013 re-enactment.

    Well I thought I'd post the companion Deck Watch to these chronometers with a little bit of history. Built at the First Moscow Watch Factory under the brand "Kirova or Kirov" these chronometer instruments were made possible by the fruits of WWII and were used by the Soviet government and military for many years. In 1935 the name of Sergey Mironovch Kirov was awarded to the watch factory in honor of Kirov who was a high level politician in the Communist party said to have reviled Stalin himself in popularity. Well needless to say he was "assassinated" probably for his success and many cities and towns and even a "Kirov Class" battle cruiser along with the watch factory were named in his honor. No evidence was ever found that linked Stalin to his death.

    This watch was manufactured in Moscow and is a very close copy if not identical of the Ulysee Nardin model. Built in Sept-Dec.1967 and with 22 jewel movement they were excellent time keepers. This one was serviced recently and keeps time to less than one second per day about as good as my Hamilton 22. Included was the factory paperwork and certification document of the watch. The tag on the box front translates to "1st Moscow Watch Factory named S.M. Kirov". The "ROCT-17156-71" represents the GOST Standard which was what the Soviet Union used at that time to mark their technical stand for products manufactured within the country. Later built instruments both chronometer and deck watch were marked "Poijot".

    Thank you Rob!.....I'll bet there are plenty of collections, that would really knock our socks off, we just have to get more people involved in posting them! I enjoy looking and I think most collectors do also at other members collections.That was the intent of this thread and with more views than any other in the chronometer section it looks like maybe it was a good idea? No....sorry I don't read Russian but I just like to find things out. The Bond isn't mine but belongs to a friend. It was a privilege to do the article on its history.

    Here is an Eggert. I believe I have discussed this one before but I thought it might be of benefit to others under this category. This is likely a Frodsham as most of the Eggerts are. They were US distributors for Parkinson & Frodsham in NYC. As can be seen in the 2nd and 3rd pics, the P & F units have shock absorbers.

    Here is a Bliss & Creighton. This one has to be before 1855 when the company split. This is one I made the missing lid for. Though it has "Patent" on the seconds bit, it does not appear as though it has any special balance and was probably re-spring at some time.

    Here is Negus 1310. Typical Negus, I know many Negus chronometers pass through the USNO however I don't believe this one did in its early life. It looks like it probably did see USN service later in its life. A nice example.

    Now that's what I'm talking about, a wonderful collection of American chronometers! I think some of the boxes more of a form of art than just a case.

    I would like to comment on the Heinrich. A German born and trained chronometer maker,inventor and author who was refereed to as a"superb craftsman","exceptional maker" and "very fine chronometer maker" by the contemporary writers of today. Heinrich began a correspondence with the U.S.N.O. as early as 1879. Working at both 12 St.John Street (1884) and 102 Fulton Street (1896) in New York city this #505 dates to probably 1888-1889. I agree this is a very rare piece as I could find no reference to Heinrich ever building a smaller size chronometer. Some European makers did and they seem to command high prices on the market. Why it was built and for whom will probably never be found out. Heinrich would also be cut out of U.S. Naval acquisition of his chronometers that had (his) auxiliary compensating balances after 1896 but did manage to have 34 of this chronometers submitted for testing. A very special piece I think.

    Thanks for your comments Burt. I have been focusing my chronometer collection on those with American names on the dial. I think I am up to 22 marine related watches and chronometers. I doubt any of my full size chronometers are true American made except for the Bond and the Bliss & Creighton.
    I think the Heinrich is using an earlier movement then what was available at the time it was sold. I agree it was from the late 1880's but the movement is much earlier. He probably used what was available at the time.
