    Mystery clock, knife edge suspension, pin wheel escapement, Huguenin a Paris

    Yes, the movement itself is 13", dial 4". One thing to look for in copies, and this was mentioned earlier is the rolled brass. All pre-1890 or so skeleton clock frames were made from casting of either the frame design or a cast/hammered brass sheet. These inevitably has some tiny and sometimes...

    Mystery clock, knife edge suspension, pin wheel escapement, Huguenin a Paris

    I have recently purchased a clock nearly identical to the one you describe, however it is the original upon which all those Chinese copies are based. Hopefully other folks will refer to this web page to check for the differences. The first thing to look for is the difference in the hands and...

    Has anyone seen this type of Seth Thomas movement?

    You are right, Time locks and alarm timers were marketed to the people who had valuables to safeguard. I have added a page with more views of the movements as well as the time lock here: Seth Thomas

    Has anyone seen this type of Seth Thomas movement?

    Pictured is what I believe to be a bank alarm timer, may be an experimental or prototype. It has a pair of what look to be high quality jeweled Seth Thomas movements. Damascened plates, dust cover and dual springs. Have these movements been used in other applications? I know that there are other...

    Telechron Type C master clock - anyone out there with one??

    I have recently obtained a Telechron Type C master clock, s/n 7, circa 1921. I am wondering if anyone else has seen or has one. Mine is missing the mercury switch tilt table and I'd like to get better photos for duplication than are available in the NAWCC Bulletin article August 1991: the only...

    Clock Kinetic Sculpture

    John, Thanks for the vote of confindence. This is exactly what we were hoping to acheive. In January of this year I began to be concerned with the pillar and plate design that we had originally developed.

    Jump Minute Tower Clock?

    While I cannot comment on the movie, or whether the movie did any tricks to get a minute jump, minute jumping tower clocks are not uncommon. They use a remontoire that has a one minute duration. Some used 30 seconds while others had 15 or even 10 to 5 seconds. One minute being most common for...

    The day I've been dreading!

    I was approached by owners of a former factory building (since converted to condominiums)here in Chicago about modernizing their clock tower. In this case the entire motion works were broken and the hands seized. The price of repair was more than the price to put in seperate motors behind the...
