    Scored a lucky find on EBay the other day! A nice 1 day torsion escapement iron clock by Theodore Terry, patented but S B Terry.
    Needs a little tidying up like servicing the movement, glueing the mounting blocks to the back board and a few other things.
    Any advice or comments greatly appreciated.

    Nice find. It took me a while, but I guess the holes in the dial are" left - regulator lever, below center - to view the motion of the pendulum balls. Interesting design. Thanks for sharing.

    Hi Tom,
    Yes you’re correct and thanks. The pendulum weights also screw in and out, I’m guessing for major adjustment and the lever is fine adjustment.
    I’m not quite sure how well the pend swing Can be seen through the lower viewing hole. I’m hoping to post a video once I have it back together.
    This is actually my 2nd one I own, the first was worked over pretty badly by someone and I’m hoping to finally figure out what’s wrong and what might be missing.
    Cheers,
    James

    Great acquisition!!

    Theo was SBT's cousin and the main stockholder and president of the firm. SB left the firm after about a year and Theo took over. His name is not found on labels nearly as often which makes your clock more interesting.

    I've previously posted a sub-miniature steeple labelled by Theo.

    Thanks for sharing your clock, James!

    Here's a thread that might provide more insight on these clocks.

    Thanks PatH,
    I forgot about this post, and I had actually commented as well to this post as well back in 2013! It reminded me that I actually have another of these clocks and had resigned it to the back of repair list as it had been badly damaged by inept hands, incorrect suspension spring, bent/damaged verge, globs of solder/lead added to the weight balls!
    Now I have a know good example so I can order/make the appropriate parts!
    Cheers,
    James

    Hi RM,
    Great looking steeple clock! Interesting there is no viewing opening for the weights? I’ve always hoped to find one of these styles.
    Going by the info on Theodore, I’ll guess the one I have is then a later production, with later modifications (adjustable weights, and slide regulator) and brass caps on the weights. Presumably Theodore was using up the remaining stock of SB as well as coming up with improved/updated cases and movements as he would have also received the patent rights. I’ve searched and haven’t seen the slide style regulator like is on my movement. Also, the other movement I have, has a Geneva stop works (attached to the front plate inside) and this movement is missing and appears to have never been fitted?
    Cheers,
    James

    Here’s the other one I have. I picked it up about 10 years ago!
    The dial was even butchered so I’m suspecting it is a replacement as the original was missing.
    Also, notice the difference in the methods of regulating between this movement (patented version), and the other.
