    While disassembling a Gilbert clock, I noticed that the loops of both springs were slit across the width of the spring [Picture below] The slits are straight and even, and do not appear to be stress breaks. They do not interfere with the loop of the spring held around the post or the operation of the clock. I'm wondering if there is a reason for these slits? Slit Spring.jpg
    Thank you!

    Paul not sure I understand..It looks to me that is just the end of the spring and then the part that goes around a post is riveted on. Perhaps I am not seeing the same slit that you are.

    I'm seeing the same as David, and think perhaps the loops were added to new springs, perhaps the new springs were too long, hence them being riveted to the ends.

    Paul,
    They are made that way. The clock does not need to be disassembled to replace or service a spring. Just let the spring down into a retainer clip, remove the special collar at the winding arbor and unsnap the spring from around the post, your done, spring is out.

    Interesting, don't see many US clocks myself willie. Is it just Gilbert that made the ends open like that as opposed to the closed loop ends seen on other US clocks?

    Out of all the clocks, Gilbert included, I've not seen this, I'd guess it was modified to keep from taking the movement apart.

    Haven't seen a set of those in a while. Like Willie said,they were made that way but you still have to blow the movement apart to remove them from the winding arbors.

    After removing the screws in the retainer, the spring and its arbor just slides out. Spring clips allow easy removal of the spring from its post. No movement disassembly required. Not really that practical today as you can't buy the springs with special clips and it's a good bit of trouble to make them.

    ST made a late #89 (D?) with removable half plate. This was a much more practical approach, as you can use common loop end springs.
